EESL assures of high quality LED Street Lights conforming to BIS standards

EESL assures of high quality LED Street Lights conforming to BIS standards

Energy Efficiency Services Limited (EESL) strongly refutes all claims of having installed faulty LED street lights in their project in the South Delhi Municipal Corporation (SDMC) area.
Under the Government of India’s Street Lighting National Programme (SLNP) over 1.98 lakh conventional street lights have been replaced with LED street lights in Delhi. A social audit of about 4,500 people was conducted by Price Waterhouse Coopers (PwC) in SDMC area in May 2016. The audit shows that at an average 99.5% people feel that the LED street lights have contributed in enhancing the security of the vulnerable groups during nights. About 99.75% of the people responded that the intensity & the brightness of the LED street lights is better than the earlier street lights.
EESL procurements conform to BIS specification & carry a 7-year warranty against technical defects. EESL conducts appropriate quality checks right from the bidding stage to the field level. This has resulted in the LEDs’ overall technical fault being less than 2% in the 14 lakh lights installed by EESL in the country. As per the contract, EESL is required to maintain an uptime of 95%, which in the present case is more than 97%. This is one of the highest in the country.
EESL is also taking proactive measures for grievance redressal, such as use of social media platforms, BSES toll free helpline, email complaint system and use of mobile vans for night patrolling. EESL is installing Centralized Control and Monitoring System (CCMS) at a fast pace to enable remote operation and monitoring of the street lights across the Nation.
For complaints against non-functioning LED street lamps the consumers can send a message via WhatsApp on 7827999222 or they can send their complaints to info@eesl.co.in. Alternatively, complaints are also being recorded on the EESL social media handles.Strict action against erring vendors is being taken by EESL.
All complaints are redressed in a period of 48-72 hours and for that EESL has deployed its own staff as well as other Project Management Companies. EESL has received just 14,850 complaints in the last two months out of 1.98 lakh streets that have been installed. EESL has already resolved over 12,406 complaints in entire SDMC area.
To address all grievances, EESL has doubled its on-field teams which are deployed for maintenance. There are regular weekly meetings and reviews with SDMC to rectify the problems faced on field which are not covered in the MoU signed by the tri-parties.
EESL has guaranteed reduction in energy consumption by 53%. This project will result in annual reduction of 26.2 million kWh of energy during peak hours. SDMC will benefit by Rs. 41.47 crore over the said period without having to invest any capital upfront.

Environment Ministry holds meeting of Stakeholders on phasing down HFCs

Stakeholders across industry groups and international experts discussed the challenges faced by India in phasing down high global warming potential (GWP) hydrofluorocarbons (HFC)s at a roundtable session held here yesterday.
Speaking on the occasion, Minister of State (Independent Charge) of Environment, Forest and Climate Change, Shri Anil Madhav Dave highlighted that India leads by example through its sustainable lifestyle habits that are key to mitigating climate change issues. The Minister also encouraged all stakeholders to focus on R&D towards implementing holistic solutions that address consumption as well as emission, as well as mechanisms to finance such initiatives. The Minister also gave an assurance that India remains committed to address the issue of Climate Change. Reaffirming India’s constructive role in global efforts to mitigate climate change, the Minister said that India would seek an equitable agreement in Kigali that is in the best interests of the nation, its people, as well as the larger global community. Shri Dave also added that the need was to focus on issues like energy efficiency, using CSR for research and development, and on demand-side management – changing architecture and consumption patterns to reduce cooling needs.
The Ministry of Environment, Forests and Climate Change (MoEFCC) hosted the roundtable discussion on “Phasing Down HFCs in India: Road to the HFC amendment to the Montreal Protocol”. Representatives from MoEFCC, civil society organisations, such as Refrigeration and Air-Conditioning Manufacturers Association (RAMA), Refrigerant Gas Manufacturers Association (REGMA), Indian Polyurethane Association (IPU), Council on Energy, Environment and Water (CEEW), National Research Development Corporation (NRDC) & The Energy and Resources Institute (TERI), as well as representatives from industry, were present at the discussion. Some of the key issues discussed at the roundtable included - opportunities and challenges in the residential and commercial air conditioning sector, cost and benefits of various transition imperatives, and issues that are likely to come up during negotiations, specifically related to patents and finance.
The Ministry reaffirmed the need to develop indigenous research and development capabilities for India specific HFC alternatives. The recent collaborative R&D programme initiated by the Ministry, to develop low GWP HFC alternatives within the country, was also highlighted.
The positive nature of multilateral negotiations and recent moves to create financial incentives for energy efficiency and India’s unique position, both as a consumer and as a producer of refrigerants at the negotiations were also highlighted. The role played by industry, in facilitating transitions in compliance with various aspects of the protocol was also recognized.
A key concern that came up during the discussions was the additional cost involved in migrating to greener technologies. According to a recent research by the Council on Energy, Environment and Water (CEEW) released yesterday, the economy wide cost for transition for India between 2015 and 2050 would be 12 billion Euros for the Indian proposal and 34 billion Euros for the North American proposal. Additional Secretary, MoEFCC, Shri R.R Rashmi said, “There are different estimates as to what it will cost to make the switch. But we must emphasise in Kigali that the commitment of donor countries has to be absolute and this assurance is necessary to fulfil any commitments India makes”. “One thing is clear. The debate is not on what needs to be done, but on how to do it. We have to make sure all parties are comfortable. A fine balance has to be achieved between national interests and environmental concerns,” Shri Rashmi added.
Experts also suggested that India should assert that funding (from the Multilateral Fund) for research and development of low GWP alternatives, and for capacity building of the servicing sector should be disbursed to developing countries as soon as possible, so that this technological transition can be achieved without any delay. International experts highlighted that early funding is available for countries to choose energy-efficient alternatives and move for an earlier phase-down.
Representatives from the industry voiced various challenges they face like patent issues, cost of moving to alternatives, lack of research on performance of refrigerants in high ambient temperature regions, and competitiveness of the industrial sector. Moreover, several voices from the industry questioned the safety, flammability and toxicity issues, with some of the low GWP alternatives and emphasised on the need for creating an incentive-structure for scaling up potential alternatives. The session also focussed on issues related to further testing and mainstreaming of available alternatives in the market, like natural refrigerants.
Earlier, Joint Secretary, MoEFCC, Shri Manoj Kumar Singh, opened the session and briefed the gathering about the importance of the upcoming negotiations in Kigali (Rwanda).
During the earlier rounds of negotiations held in Bangkok, Thailand in 2015, India had, taken a leadership role by proposing an amendment to the Montreal Protocol, recognizing the need to phase out HFCs, while also rationalising the costs associated with such a transition.

Minister of Railways Launched and Dedicated Various Services to the Nation

Shri Suresh Prabhakar Prabhu, Minister of Railways during a function held at Rail Bhawan today i.e. 29.09.2016, as a part of fulfilment of Budget Announcements 2016-17, launched and dedicated following services to the nation : -

1. Liberalised station to station special freight rates policy
2. Policy providing sub quota of 33 % to women within reserved categories for the allotment in catering units.
3. Policy giving preference to local domicile holders for commercial licenses at stations.
4. New system of allocating vacant berths after final charting to wayside stations.
5. Launch of the new “Train at a Glance” and new Time Table effective from 1st October 2016.

Shri Rajen Gohain, Minister of State for Railways was especially present on the occasion. Chairman, Railway Board, Shri A.K. Mittal, Member Traffic Mohd. Jamshed and other Railways Board Members and dignitaries were also present on the occasion.

 Speaking on the occasion, Minister of Railways Shri Suresh Prabhakar Prabhu said that the Indian Railways is striving hard to achieve full passengers’ satisfaction in all respects and today’s initiatives are part of our such endeavours.  He said that the introduction of new policy providing sub-quota of 33% to women in catering units is a step towards women empowerment and their increased participation in Railways.  He said that Railways will continue to introduce such new reformative steps.

Speaking on the occasion, Minister of State for Railways Shri Rajen Gohain said that Indian Railways being the biggest organization of the country has lots of complex projects to implement throughout the country. But overcoming the difficulties and complexities, Railways is implementing its budget announcements in a very promised manner which is a landmark in itself. 

Salient Features of the initiatives : -

POLICY PROVIDING SUB QUOTA OF 33 % TO WOMEN WITHIN RESERVED CATEGORIES FOR THE ALLOTMENT IN CATERING UNITS

·         In compliance of Budget Announcement 2016-17, a Sub Quota of 33% for women in allotment of each of the reserved catering units is being introduced on Indian Railways in order to extend economic empowerment for women.

·         Current Status of Reservation at Minor Catering Units (Stalls / Trolleys / Khomchas)

·         A1, A, B, and C Category stations – 25% of the Units are reserved for various categories like SC (6%), ST (4%), BPL (3%), OBC (3%), Minorities (3%), Freedom Fighters (4%) and Physically Challenged persons (2%).

·         D, E and F Category stations – 49.5% of the Units are reserved for various categories like SC (12%), ST (8%), OBC (20%) and Minorities (9.5%).

·         33% sub quota reservation for women shall ensure allotment of minimum 8% stalls to women at A1, A, B & C category station and minimum 17% at D, E and F category station.

·         There are approximately 8000 Minor Catering Units over Indian Railways.

·         Under this provision, Railways shall ensure that women participation does not fall below a specific level.

POLICY GIVING PREFERENCE TO LOCAL DOMICILE HOLDERS FOR COMMERCIAL LICENSES AT STATIONS

In compliance of Budget Announcement 2016-17, a process of giving weightage to district Domicile Holders for commercial licenses at stations is being proliferated at all stations over Indian Railways.

·         The proliferation would help to build local ownership and rural empowerment along with socio – economic development.

·         The weightage to district domicile holders is being proliferated for allotment of Catering Units at all categories of stations.

·         The proliferation of weightage to district Domicile Holders at all category of stations will ensure protection of livelihood of the small vendors.

·         The allotment of Minor Units over Indian Railways will ensure local ownership and will also promote regional / local cuisine, which is always a preferred choice.

·         The weightage parameter would range from 20% to the local District Domicile holders to 12% to the State Domicile holders in techno-commercial scores.

TRANSFER OF VACANT BERTHS FOR OPTIMAL UTILISATION OF BERTHS

·         IR is introducing the facility of transfer of berths remaining vacant after second charting at the train originating station to the next and subsequent stations for clearing the waitlisted passengers at such stations.

·         The PRS system will automatically allot vacant berths available at the originating stations after preparation of second chart to the subsequent stations where waitlisted passengers are available. The passenger will get SMS on his registered mobile indicating the coach and berth number allotted. This will help passengers boarding at road side stations to get confirmed berths. Presently they get their berths confirmed only if confirmed berths from the pooled quota (PQ) allotted to the station are cancelled.

·         The TTEs will be able to allot vacant berths on board after departure of the train only upto the next station where quota is available for the train. In case no person boards the train at the next station he can further allot/extend the same to the next quota station.

·         At present about 3 lakh berths per year go unutilised while there may be demand at intermediate stations. This system will help in better utilization of available berths at the time of departure of trains from the originating station and also reduce the discretion available with TTEs in allotting the berths.

LIBERALISED STATION TO STATION SPECIAL FREIGHT RATES POLICY

·         Section 32 of the Railways Act, 1989 empowers railway administration to quote Station to Station Rate (STS) in respect of carriage of various commodities. 

·         Railway Board used to issue guidelines to Zonal Railways for implementation of STS rates. Last guidelines on this subject were issued by Board in 2002, which were in operation till 2006. In November 2015, Zonal Railways were advised to exercise power vested with them to quote STS rates as per the Railways Act, 1989.

·         On request from Zonal Railways and to enable them to garner more traffic from road and other modes,   broad guidelines are being issued to Zonal Railways for finalising STS rates.

·         Salient features of the proposed policy are as under:

·         Existing as well as new traffic shall be eligible.

·         Concession shall be granted up to a maximum of 30% on the incremental traffic over and above the benchmark NTKM. Benchmark NTKM is defined as average NTKMs of corresponding periods of previous 24 months.

·         Concession shall be in the form of percentage discount over the Normal Tariff Rate (NTR). It should be ensured that the concessional freight should not be less than the NTR of Class 100.

·         Concession shall be admissible to Block rake, two/multi point rake, Mini Rake etc.

·         Concession may be granted for retention of traffic also up to maximum of 15%. In case of container traffic, STS discount upto maximum of 15% shall be given to commodities charged at Container Class Rate (CCR).  

·         STS scheme will be applicable for all terminals namely goods sheds, sidings, ports, CRTs, PFTOs etc. 

·         To avail STS, Rail users shall be required to apply to the DRM with details, who shall forward the same for approval of GM through CCM, COM and FA&CAO.  If Railway administration approves grant of concession under STS, an agreement shall be executed between Railway and customer.

·         The agreement shall be done for a maximum period of three years at a time and for not less than one year.  Any change in freight rate (excluding imposition of any surcharge) shall not be applicable on the customer during the currency of the agreement or for one year, whichever is less. 

·         Commodities excluded from STS are - 

o   All commodities with classification below Class-100.

o   All commodities under Main Commodity Head “Coal & Coke”

o   Iron ore (all types)

o   Military traffic, POL and RMC

·         Targeted customer:  Food grain, Cement, Clinker, Dolomite, Limestone, Steel companies, Fly ash, etc.

·         Expected additional loading: 10 million tonne per annum.

LAUNCH OF NEW TAG

            The launch of  Trains at a Glance 2016- the new Time Table effective from the 1^st October has also been launched.

A BRIEF OVERVIEW

With over 66 thousand kilometres of route ( 1/3 rd of which is electrified), more than 7000 stations, above 10,000 locomotives and more than 60 thousand coaches, Indian Railways runs above 13000 passenger carrying trains  - to take about 23 million passengers to their destinations -  everyday.

The journey in Passenger Operations in the last two years has been one of sustained efforts to provide additional capacities, improve the quality of travel experienceand to reach out to all types of passengers including those in far flung areas. As can be seen, funds to the tune of 8.56 Lakh crore are already tied up for these purposes for 2-15-19 and have started bringing results.

Additional  services provided in last 2 years include 308 new trains, 99 extensions, 118 trains whose frequency was increased and permanent addition of 1610 additional coaches.

We have also met additional demand by running more than 70 thousand special trains  including those to meet extra rush, election movements, military and para-military movements, and tourist trains. Besides, more than 2.5 lakh extra coach trips have also been provided - as per need.

We have been migrating to better coaches - with more comfort and speed.  38 trains have been provided the modern LHB coaches and 40 trains converted to the faster and superior MEMU coaches.

We have also added trains to new areas including  Sri Mata VaishnodeviKatra, Arunachal Pradesh , Barak Valley and many more.

In the current Year, the efforts to improve service levels in passenger operations have gained further momentum. What has already been done in the current year includes premium trains like Mahamana and Gatimaan express,aneven more accelerated transition to superior coaches including the new DeenDayalu coaches started from August,  More Permanent augmentations, and further efforts to meet additional demands.

The current year has seen several large religious and other congregations of people which have been managed effectively,  to the comfort of our passengers , with record running of special trains and extra coaches and effective overall bandobast,. This includes the SimhasthaMela in Ujjain, the krishnapushkaram on the Krishna Basin and so on. The arrangements for the ensuing Durga Puja rush are also completely in place.

The highlights of the improvements planned in the new Time table that will come into effect from the 1^st October, 2016, include most importantly, the specifics of the 4 new brands of train products.

Further, in this timetable, we have also reduced the journey times in 350  existing trains, 75 of which have made it to the superfast category.

We have converted 240 operational halts into commercial stoppages and have for the first time, provided in the time table, train connectivities to the North Eastern states of Tripura, Manipur and Mizoram.

Also incorporated in this  Time Table - are  36 pairs of new services, some of which have been introduced in this financial year and some that will be coming soon- like the  10 pairs of Humsafar trains, 7 Antyodaya, 3 Tejas and 3 UDAY trains besides a number of other mail express trains, extensions, increase in frequency, diversions etc.

Infact, the  4 diversions mentioned at the end of the last slide shall become effective from the 1 st October. These will cater to a long pending demand of the people of Cuttack who will now get a direct connectivity instead of the detour these trains were earlier taking.

The contours of the new train products incorporated in the New Time Table are brought out here.

Cabinet approves ratification of the Paris Agreement

Cabinet approves ratification of the Paris Agreement

The Union Cabinet chaired by the Prime Minister Shri Narendra Modi has given its approval to ratify the Paris Agreement (on Climate Change) on 2nd October 2016, the day of Gandhi Jayanti.

Paris Agreement was adopted by 185 nations last year on 12th December 2015 and India signed the Paris Agreement in New York early this year on 22nd April 2016. A total of 191 countries have signed to the Paris Agreement so far. As per the provisions of the Paris Agreement, the treaty will come into force as and when 55 countries contributing to 55 % of total global emission ratify the agreement. So far, 61 countries have deposited their instruments of ratification, acceptance or approval accounting in total for 47.79% of the total global greenhouse gas emissions.

India’s decision to ratify the agreement will take the number of cumulative level of emission of countries that have ratified the agreement so far to 51.89%. With the gathering momentum and willingness expressed by several other countries to ratify the agreement before the end of this year, it is expected that the Agreement will enter into force soon and give a thrust to the global actions to address climate change.

With its decision to ratify the Agreement, India will be one of the key countries that will be instrumental in bringing the Paris Agreement into force. Given the critical role that India played in securing international consensus on Paris Agreement, today’s decision will further underline India’s responsive leadership in the community of nations committed to global cause of environmental protection and climate justice.

While agreeing to ratify the Paris Agreement, the Cabinet has also decided that India should declare that India will treat its national laws, its development agenda, availability of means of implementation, its assessment of global commitment to combating climate change, and predictable and affordable access to cleaner source of energy as the context in which the Agreement is being ratified.

Paris Agreement pertains to post-2020 climate actions. In the pre-2020 period, developed countries are to act as per Kyoto Protocol and some developing countries have taken voluntary pledges.

TYPES OF CHEMICAL HAZARDS- UNDERSTANDING M.S.D.S. OF CHEMICALS

TYPES OF CHEMICAL HAZARDS- UNDERSTANDING M.S.D.S. OF CHEMICALS

People working in chemical factories and dwelling nearby are exposed to various types of chemical hazards. Inflammable, explosive, toxic, corrosive, reactive, radio active, oxidising, reducing, decomposing, compatible and hidden hazardous nature of chemicals pose material or property hazards. In process, chemical and physical change, chemical reaction, pressure, temperature, level, flow, quantity and other parameters create process hazards. The vessels and equipment in which the chemicals are stored, handled or processed, pose vessel hazards. The inadequate, defective, under designed or wrongly modified control devices or failure thereof cause control hazards. Fire or explosion cause fire hazards. Effluent disposal and gaseous emissions bring pollution and toxic hazards. Leaks, spills and splashes cause handling hazards. Absence, non-use or failure of fire fighting equipment, personal protective equipment, emergency control devices reveal accident and emergency hazards. All other unsafe working conditions and unsafe actions pose a variety of hazards that all need to be prevented and controlled. Many safety measures are available to deal with above hazards. Identification of contents, properties, hazards and quantity of chemicals, their content minimisation, proper storing, handling and packing; auto control, recording and warning devices for level, pressure, vacuum, temperature, flow, feed, speed, cooling, heating, stirring, discharge, contamination; remote control devices, proper ventilating, exhaust, scrubbing, neutralising, inactivating and incinerating devices; monitoring, measuring, recording, tripping, correcting and controlling system, fire fighting and personal protective equipment, emergency and disaster planning, controls and all engineering well designed process and plant layout and fully safe actions of work-people are utmost necessary to fight these hazards and to control over them. The basic steps in short are as follows : 1 Identification of Health (Toxic) Hazards : (a) Types of effects are - Allergy, Irritation, Oxygen deficiency (asphyxiation), Systemic poisoning (eg damage to liver, kidney, CNS, reproductive system etc.), Cancer, Damage to unborne foetus(teratogenesis), Genetic effects on future generations (mutagenesis), Dust effect (pneumoniosis). Some effects are acute (local or short term) and some are chronic (long term, delayed or after repeated exposures). (b) Factors creating effects are - Type of concentration of chemical, Combined effects of mixtures, Properties of the material including its toxicity, Work methods, Nature of exposure (short term, long term) Routes of entry (through nose, mouth or skin) and Individual susceptibility. 2 Identification of other hazards : (a) Fire and Explosion Hazards : Heat generation due to chemical reaction, Open flame, Radiant heat, Fricton, Spontaneous combustion, Electric current, Static electricity etc. (b) Fuel or Solvents - Low flashpoint and Low boiling point liquids, Gases and Solids (dusts, powders, lumps, crystals) (c) Atomic Radiation - Radioactive substances and Radiation processes (X-ray, NDT, Nuclear power plant etc.) 3. Preventive & Control Measures : (a) Six Basic Principles - · Elimination of substance or process. · Substitution of safer alternative. · Distance, Guard, Enclosure, Isolation, Shielding or Segregation of hazardous process. · Ventilation, general & local exhaust. · Personal Protective Equipment. · Personal hygiene. (b) Management Control - Identification, MSDS, Labelling, Safe storage, Safe Transfer procedure, Safe handling & use, Safe processes & operations, Safe disposal methods, Good housekeeping, Measurement & assessment (Monitoring), Medical examination, record and treatment (medical surveillance), Record-keeping of work exposure monitoring, environmental or air quality monitoring, medical and biological monitoring, Training & education to workers and Supervision including safety work permits and safe work methods. 4. Emergency Control Procedures : · Speedy Leak & Spill Control procedures. · Emergency shut-down procedure. · On site emergency plan. · Off site emergency plan. · Mutual aid arrangement with neighbouring industries. · Retainer ship for help at the time of emergency. · Regular rehearsal of emergency procedures (drill), updating and reviewing of the plan. MATERIAL (PROPERTY) HAZARDS AND CONTROL Make a list of all raw materials, products, by-products and intermediates. Identify them by their nature of hazard and risk potentials. Classify them as inflammable, explosive, toxic, corrosive, radioactive, reactive, oxidising, irritant, unstable, compressed gases, dust and others. Also note their hazardous properties viz. boiling point, flash point, LEL, UEL, LD, LC, TLV, MAC, IDLH, density, solubility etc., to understand the ill-effects of the chemical. Reference No. 1 to 4 given at the end of this chapter explain all such terms and give them for various chemicals. Reference No. 11 gives such hazardous properties of some selected chemicals. The chemicals may cause either physical hazards or health hazards. The physical hazards are caused due to dust, corrosive, explosive, flammable and reactive chemicals, compressed gases and oxidisers. The health hazards are caused due to toxic, irritant and carcinogenic chemicals. Carcinogenic causes cancer. Mutagenic causes inherited changes and teratogenic causes harm to unborn. Micro-organisms and radioactive chemicals also cause health hazards. The hazards are also classified as first and second degree hazards. The first degree hazards are caused by corrosive, flammable, explosive, toxic and oxidising chemicals, heat or ignition source, human error and failure of equipment etc. The second degree hazards injure life and property and include fire, explosion, toxic exposure, corrosive chemicals, collision, slipping, falling etc. Identification of Chemicals Identification of chemicals begins with the knowledge of basic chemistry. Refer Table No. 1 in Chapter 32 to identify first some commonly used elements and radicals. This will help to identify the chemicals. Chemicals are classified in different ways. For study (chemistry) point of view, they are broadly classified as inorganic and organic chemicals. Inorganic chemicals are subclassified as metals and non-metals. Out of 104 elements, 80 are metals and majority of them (except mercury) are solids, shining, reflecting, good conductor and forming reducing agents and basic hydroxides. In non-metals, more than half are gases and remaining are hard solid, non-shining, less reflective, bad conductor and forming oxidising agent and acidic hydroxides. Some examples are given below : Metals : Aluminium, Arsenic, Beryllium, Calcium, Chromium, Cobalt, Copper, Iron, Lead, Manganese, Mercury, Nickel, Radium, Sodium, Tin, Uranium, Zinc etc. Non-metals : Bromine, Chlorine, Fluorine, Iodine, Oxygen, Phosphorous, Sulphur etc. Organic chemicals include carbon compounds. They are subclassified as under - Aliphatic Compounds (without benzene-rings) : Hydrocarbons, Halogen derivatives of paraffin, Alcohol, Ethers, Aldehydes, Ketones, Carboxylic acids and their derivatives, organic compounds of Nitrogen and Sulphur, Carbohydrates, Alicyclic compounds etc. Aromatic Compounds (with benzene-rings) : Benzene and its derivatives, Aromatic amines, Diazo compounds, Dyes, Phenols, Aromatic alcohol, Aromatic aldehydes, Ketones and quinones and Aromatic carboxylic acids. Heterocyclic Compounds and Polymers (with other-rings) : Furan, Pyrrole, Thiophene, Pyridine, Quinoline, Isoquinoline, Alkaloids-coniine, nicotine, Drugs, Hormones, Vitamins, Enzymes and Polymers - Natural and Synthetic Rubber like neoprene, butadiene; synthetic fibres like nylon, orlon, vinyon, terylene, Synthetic plastics and resins like cellulose, formaldehyde, alkyd, vinyl, acrylate and polystyrene resins and silicones. Chemicals are also classified as under : 1. According to their Physical State i.e. solid, liquid or gases. Fine particles of solid like powder, dust, fumes and smoke are called particulate matter. Their suspension in air or gas also exists. Liquids are classified as acid, alkali, solvent, suspension, liquid mixture, aerosols etc. Gases are classified as inert (N2, CO2), reactive, toxic, irritant, corrosive etc. 2. Noxious Gases : · Irritant gases - Cl2, NH3, SO2, NO2, COCL2, Aldehydes etc. · Systemic poisons - C6H6, CS2, PH3, Stibine, Mn, Nickel carbonyl, Arsine, Halogenated hydrocarbons etc. · Simple asphyxiates - N2, CH4, CO2 etc. · Chemical asphyxiates - CO, H2S, HCN etc. 3. Dust (Particulate Matter) : · Causing plenumoconioses - Coal, Silica, Asbestos etc. · Causing Asthma - Cotton, Flour, TDI etc. · Causing allergy - fungal spores, bird fanciers, lung, bagassation etc. · Causing lung cancer - Chromium, Asbestos, Benzene etc. 4. Biological Agents and Diseases : · Virus Rickettisia - Psittacosis, rabbis etc. · Bacteria - Anthrax, Woolsorter's disease, Leptospirosis or Weal's disease, Brucellosis, Tetanus etc. · Fungi - Ringworm, Moniliasis etc. · Parasites - Hookworm · Plant products - Dermatitis due to mango tree and cashew seed processing. For details see the Schedule given under the Rules for manufacture, use, import, export and storage of hazardous micro-organism, genetically engineered organism or cells (Refer Part 2.34 of Chapter-28).

Disclaimer : 7.3 Interpretation and use of MSDS For the better understanding and use of the Material Safety Data Sheet, some terms are explained below : 1. Formula (Chemical) : It is a symbolic representation of a chemical entity or relationship between elements, molecule and atoms. e.g. H2 one molecule of hydrogen, 2H2SO4 two molecules of sulphuric acid, H2O one molecule of water wherein there are two atoms of hydrogen and one atom of oxygen. C6H6 benzene contains six atoms of carbons and six atoms of hydrogen in one molecule, group or ion. Thus by formula we can know the hazardous ingredient of a chemical. 2. Synonym : Indicates alternate name of a material. e.g. Dimethyl ketone or 2-Propanone for Acetone. 3. Trade Name : Commercial name of the product. 4. Chemical Classification : General classification is organic or inorganic. Hazardwise classification can be flammable, explosive, toxic or poisonous, corrosive, reactive, infectious, oxidising, radioactive etc. 5. CAS No. : It is Chemical Abstracts Service number to provide a single unique identifier with naming the chemical. e.g. CAS No. for acetic acid is 64-19-7. It does not indicate the hazards of a material. 6. UN No. : It is United Nations four digit number assigned to potentially hazardous material (e.g. Ammonia UN No. 1005) or Class of material (e.g. corrosive liquids UN No. 1760). These numbers are internationally recognised and used by emergency response personnel (including ire fighters) to identify material during transport emergencies. UN, Hazchem, NA and PIN numbers have the same uses. 7. Hazchem (EAC) No. : Hazchem (hazardous chemical) Code or EAC (Emergency Action Code) is an emergency code confirmed by the Health & Safety Executive, UK. It consists of a number (1 to 4) followed by one or two letters and signifies type of a fire extinguisher required, type of personal protective equipment required, whether the spillage should be contained or diluted with water, whether the material is reactive and whether evacuation of the surrounding area necessary. Hazchem No. of Sodium cyanide is 4X and that of Vinyl chloride is 2WE. 8. ADR No. : It is an Agreement concerning carriage of Dangerous goods by Road. This European agreement was arrived at Geneva by 19 European countries for the safety of international transport by road. It deals with the classification of hazardous substances, their packaging, loading and unloading, transportation and its equipment. It gives hazard identification numbers like UN hazard class number. Their comparison is given below. Classification of Dangerous Goods by UN Number ADR Number 1 Explosives. 2 Emission of gas 2 Gases- Compressed, due to pressure or liquefied, dissolved due to chemical under pressure or reaction. deeply refrigerated. 3 Flammability of 3 Flammable liquids. liquids (vapours) 4 Flammable solids. and gases. 5 Oxidising 4 Flammability of substances or gases.

Doubling (repeating) of an ADR digit indicates increase of that particular hazard. Prefix 'X' indicates that the substance can dangerously react with water. As an example ADR HIN (Hazard Identification No.) of Benzene is 33 (UN No. is 1114 and Hazchem No. is 3WE). 9. Appearance, State, Odour : Appearance includes colour. State means physical state - solid, liquid or gas. Odour indicates smell. Odour threshold is that minimum level (ppm) where the odour will start. If odour threshold is lower than the permissible safe limit (e.g. TLV, STEL, IDLH or LC), the odour indicates the presence of gas and some safety margin is available to run away or to take precautionary step. But if it is higher, the gas becomes toxic or hazardous before its odour starts and this condition is risky. In that event a reliable gas detector is useful. Sometimes odour is added to detect the gas leakage e.g. addition of mercaptan in domestic LPG. Ability to detect odour may vary from person to person and may mislead if the other odorous materials are simultaneously present. 10. Specific Gravity (water = 1) : It is the ratio of the density of a material to the density of water (which is 1 g/cc). Lighter material (Sp. gr. <1, e.g. benzene 0.88) will float and heavier material (Sp. gr. >1, e.g. sulphuric acid 1.84) will sink. This information is useful for spill or fire control. 11. Vapour Density (air = 1) : It is the vapour weight per unit volume. In MSDS it is given as the ratio of the density of a gas or vapour to the density of air. The air density is 1.293 gm/l, but here it is considered as 1 for easy comparison of gases. Lighter gases (Vd<1, e.g. ammonia 0.59) will go up (rise) in the air and heavier gases (Vd>1, e.g. chlorine 2.49) will come down on the bottom. This information is useful for ventilation design and evacuation (emergency) activity. 12. Boiling Point : It is that temperature at which the material changes from a liquid to a gas. Below this point the liquid can evaporate to form vapour but at the BP the change from liquid to vapour is faster. This increases the vapour concentration and its pressure. This condition poses higher risk of fire, explosion or toxicity. 13. Thermal Decomposition Products : If the material decomposes (breaks down) without boiling, the temperature at which it decomposes is given with the word 'dec'. Some of the decomposition products are hazardous. The thermal decomposition products may be quite different from the chemicals formed by burning the same material (hazardous combustion products). Information regarding thermal decomposition is useful to design ventilation system where a material may be heated. 14. Hazardous Decomposition Products : They are formed when a material decomposes (without heating) because it is unstable or reacts with common material like water or air (oxygen). This information is useful to design storage and handling procedures. For example, phosgene decomposes into corrosive and toxic fumes of HCl and CO because of heating or coming into contact of water or steam. Here HCl and CO are hazardous decomposition products. 15. Hazardous Combustion Products : These are the chemicals which are formed when a material burns. They may be toxic, flammable, smoke, carbon particles or other hazards. Their amount varies according to temperature and oxygen (air) available. They may be different from the thermal decomposition products. This information is useful to decide the fire fighting material and procedure. 16. Melting Point : It is that temperature at which a solid material melts and becomes a liquid. This information is useful for storage and handling purpose. A melted material may distort a container. 17. Freezing Point : It is that temperature at which a liquid material freezes and becomes solid. This information is useful for storage and handling purpose. A frozen material may burst a container. 18. Vapour Pressure : It is the pressure (mm of Hg) upon atmosphere of the vapour of a material at a fixed temperature (e.g. 20 0C). Higher vapour pressure indicates higher concentration and therefore higher hazard due to fire or inhalation. 19. Solubility : It is the ability of a material to dissolve in water or another liquid (solvent). It may be expressed as a ratio or described by words like insoluble, very soluble, sparingly soluble or miscible. This information is useful to decide a scrubbing media, spill control or fire fighting material and procedure. Such solvent should not be hazardous. 20. Scrubbing neutralising or inactivating media : These are those materials (liquids) which dissolve or react with the hazardous material (gas, liquid or solid) to diminish its hazardous exposure e.g. caustic, lime, water etc. If this is not possible, proper absorbent may be used e.g. sand, sponge rubber etc. See Part 8.5 and Table 18.6 of this Chapter and Table-17 of Chapter-32 for scrubbers. 21. pH : It is a measure of the acidity or alkalinity (basicity) of a material when dissolved in water. It is expressed in a scale from 0 to 14 as under : pH 0 - 2 Strong acidic 3 - 5 Weak acidic 6 - 8 Neutral 9 - 11 Weak basic 12 - 14 Strong basic This information is useful to select a neutralising material for scrubbing or effluent treatment or spill control. 22. Flash Point : It is the lowest temperature at which a material gives off enough vapour near its surface to form a flammable air vapour (gas) mixture so that it can be ignited if a spark is available. The lower flesh point indicates higher hazard as it can cause fire at a lower temperature. It is expressed as Closed Cup (CC) or Open Cup (OC). CC value is slightly less than the OC value. 23. Autoignition Temperature : It is the lowest temperature at which a material begins to burn in air without any contact of spark or flame. During heating if the material decomposes, the decomposed chemical may auto-ignite at some other temperature. Different test methods give different auto-ignition temperatures for the same material. Therefore this value is an estimate. The material should be stored, processed or handled well below its auto-ignition temperature to avoid the risk of self fire or explosion. Substances liable to spontaneous combustion are those liable to spontaneous heating under normal conditions or to heating up on contact with air and being then liable to catch fire. 24. Flammable or Explosive Limits (LEL/UEL) : The lowest concentration (percentage in air) of gas or vapour which will burn or explode if ignited, is called the Lower Explosive (or Flammable) Limit i.e. LEL or LFL. The upper concentration (percentage in air) of gas or vapour which will burn or explode if ignited, is called the Upper Explosive (or Flammable) Limit i.e. UEL or UFL. The range between LEL and UEL is called the Explosive (or Flammable) Range. The fire or explosion risk lies within this range but not out of it. Below LEL the gas-air mixture is too lean to ignite and above UEL it is too rich to ignite. However the concentration above UEL should be considered dangerous as due to entrainment of fresh air, it may be diluted and enter the explosive range. Similarly after LEL if gas discharge is continued in the same air, it can also enter the explosive range. Thus explosive range can be reached depending on flow of gas and air affecting their concentration. Air and gas temperature may also affect. Therefore the range should be considered as approximate values. For gas/vapour it is expressed in % of air (1% = 10,000 ppm) and for powder in gm/m3 of air. This information is useful to avoid the conditions leading to the explosive range and to ascertain it before allowing any person to enter any vessel or confined space where such air-gas mixture is suspected. Explosimeters are available to detect this range. Detection should be of percentage of LEL and all safety devices (alarms, controls, trips etc.) should operate well below the LEL. Fire hazard should be prevented at pre-determined percentage of LEL. 25. TDG Flammability : Transport of Dangerous Goods (TDG) classifies the materials according to their flammability as under - 2.1 Flammable gas. 3 Flammable liquid (Subclasses 3.1, 3.2 and 3.3 based on flash point). 4.1 Flammable solid. 4.2 Spontaneously combustible material. 4.3 Material which gives off a flammable gas on contact with water. 26. Explosion Data (Sensitivity) : It gives explosive properties of a material e.g. low, moderate or high. It gives two types of sensitivity : Explosion Sensitivity to Impact - It indicates whether or not the material will burn or explode on shock or friction, and Explosion Sensitivity to Static Electricity - It indicates how readily the material can be ignited by an electric spark or static discharge. 27. Explosive Material : An explosive material is that material which can explode on impact or by electric spark. Schedule-1 of Manufacture, Storage and Import of Hazardous Chemicals Rules, 1989 defines 'Explosives' as those chemicals which explode under the effect of flame, heat or photo-chemical conditions or which are more sensitive to shocks or friction than dinitrobenzene (old definition) or pyrotechnic substance (firework) or which is capable of producing gas at such temperature, pressure and speed to cause damage to surroundings or exothermic reaction by heat, light, sound, gas, smoke or their combination (new definition). 28. Combustible and Flammable Material : Flammable solid, liquid or gas which can catch fire and burn rapidly or explosively are flammable materials. The terms combustible and flammable both indicates the ability of a material to burn. Any material that will burn at any temperature is combustible by definition. Flammable are a special group of combustible materials that ignite easily and burn rapidly. For example, NaCl, CCl4 and CO2 are non-combustible while sugar, cellulose and ammonia are combustible but non-flammable. The more readily ignition occurs, the more flammable the material, less easily ignited materials are said to be combustible, but the line of demarcation is difficult to decide. Normally combustible liquids are classified as those whose flash point is greater than 37.70C (100 0F). Flammable or Inflammable liquids are classified under MSIHC Rules as (1) Extremely flammable - having FP<230C and BP<350C (2) Very highly flammable liquids - having FP<230C and BP>350C (3) Highly flammable - having FP between 230C and 600C and (4) Flammable - having flash point between 600C and 900C. Thus liquids having flash point between 37.70C to 900C can be called combustible as well as flammable, while those having flash point greater than 900C should be called combustible. Flammable liquids are extremely hazardous, as they give off vapours at low temperature and these vapours by travelling to a source of ignition can cause flash back to the flammable liquid. It is difficult to extinguish a burning flammable liquid with water because water may not be able to cool the liquid below its flash point. Flammable gases (normally boiling point < 20 0C) are equally hazardous as flammable vapours as explained above. Confined flammable gases are most dangerous. Flammable gases are also defined as those which at 200C and at standard pressure of 101.3 KPa, have LEL 13% or less or a flammable range of 12% or more regardless of the LEL. Flammable solids can be ignited due to external heat, flame, process heating by interaction with water or other substances. Flammable solids are of various types (1) Dusts or fine powders e.g. cellulose, flour etc. (2) Spontaneously ignitable at low temperature e.g. yellow phosphorous (3) Those in which internal heat is built-up by microbial or other degradation activity e.g. fish meal, wet cellulosic material (4) Films, fibres and fabrics of low-ignition point materials. Flammable solids are readily combustible or may cause or contribute to fire through friction or which are liable to undergo a strong exothermic reaction. 29. Corrosive Material : It can attack (corrode) metals or human tissues such as skin or eyes. Structure or metal container may become weak and eventually collapse or leak. Skin, eyes or other body parts can be badly affected (burning) by corrosive materials. Acids, halogen gases, chlorides, caustic, phenol etc. are corrosive. 30. Hazardous Polymerisation : A polymer is a natural or man-made material formed by combining units called monomers, into long chains. e.g. styrene is the monomer for polystyrene. Polymerisation is the process of forming a polymer by combining monomers into long chains. Uncontrolled polymerisation can be hazardous, as it can cause heat, pressure or explosion. Some chemicals can polymerise on their own without warming, others upon contact with water, air or common chemicals. Vinyl chloride rapidly polymerises in presence of light, air or heat. Therefore polymerising conditions should be controlled properly. Inhibitors(negative catalysts or compounds that retard or stop an undesired chemical reaction such as polymerisation, oxidation, corrosion etc.) are normally added to products to reduce or eliminate the possibility of hazardous polymerisation. 31. Pyrophoric Material : Any liquid or solid that will ignite spontaneously in air at about 54.4 0C (130 0F). Titanium dichloride and phosphorous are examples of pyrophoric solids, tributylaluminium and related compounds are pyrophoric liquids. Sodium, butyllithium and lithium hydride are spontaneously flammable in moist air as they react exothermically with water. Such materials must be stored in inert gas or under kerosene. Some alloys (barium, misch metal) are called pyrophoric because they spark when slight friction is applied. Pyrotechnic materials mean fireworks. Catalysts of pyrophoric material which can burn in normal air, are replaced in the atmosphere of nitrogen blanketing. The workers have to wear self-breathing apparatus while doing such job, because in the atmosphere of about 90% nitrogen, oxygen is insufficient for breathing. 32. Oxidiser and Peroxide : It is a compound that spontaneously evolves oxygen either at room temperature or under slight heating. Oxidisers include peroxides, chlorates, perchlorates, nitrates and permanganates. These can react vigorously at ambient temperatures when stored near or in contact with reducing materials (that will remove oxygen or add hydrogen) such as cellulosic and other organic compounds. Storage areas should be well ventilated and kept as cool as possible. Peroxides release atomic (nascent) oxygen readily. They pose fire hazards in contact with combustible materials, especially under high temperature conditions. They are used as oxidising agents, bleaching agents and initiators of polymerisation. Oxidizing substances are not necessarily combustible in themselves but by giving oxygen they contribute to combustion of other materials. Organic Peroxides contain bivalent 0-0-structure, are thermally unstable and may undergo exothermic self-accelerating decomposition. 33. Chemical Stability : A stable compound does not easily decompose or react readily. Chemical stability is the ability of a material to remain unchanged in the presence of heat, moisture or air. An unstable compound may decompose, polymerise, burn or explode under normal environmental conditions. Special precautions are required to store or handle unstable materials. For examples, CS2 decomposes in light and burns due to heat, spark, flame or friction and gives off toxic fumes of SOx. Caprolectum liberates NOx fumes due to heating. TNT explodes due to heavy shock or by heating. Thus conditions disturbing stability must be known. 34. Incompatibility : Compatibility means the ability of two or more materials to exist in close and permanent association indefinitely. Liquids and solids are compatible if the solid is soluble in the liquid. Water is compatible with alcohol (because it is miscible) but not with gasoline (e.g. petrol). Incompatibility means disability to co-exist permanently. Therefore incompatible materials should not be stored or kept together. For example, toluene reacts violently with some acids, plastic or rubber, therefore, these substances should be kept away. Incompatible materials can cause a fire, explosion, toxic release, violent reaction, polymerisation or destroy the structure or function of a product. This information is useful for storage and handling purposes. 35. Reactivity : Two or more chemicals can react with each other and give reaction products. e.g. 2H2 + O2 = 2H2O. A single chemical can react with air or water (which are also chemicals) and give the product. e.g. phosphorous burns in air and gives its oxides (P2O3, P2O5), sulphur burns and gives SO2 etc. Reactions are exothermic when they evolve heat and are endothermic when they need heat to maintain them. A reversible reaction is one in which the reaction product is unstable and goes back to the original substance spontaneously. In MSDS we are concerned with the hazardous reaction or reactive material which can cause fire, explosion, toxic release or violent reaction with air, water or common chemicals or under environmental conditions. Phosphorous, CS2, Sodium metal, acids (reactive with metals) etc. are known for their reactivity. This information is useful for storage, handling and process safety purposes. 36. Hazardous Reaction Products : These must be known for the safety of process, workers and environment. Here products are more important than the reaction because of their hazardous nature. e.g. Chlorine reacts with alcohol and forms explosive alkyl hypochlorite. If toxic fumes are to be generated, scrubbers are required, if flammable vapours are generated, inert gas blanketing is required and earthing of the vessel also becomes necessary. If reaction products are highly poisonous like NaCN, HCN etc., they are to be handled in a closed system. 37. Health Hazard Data : For TLV, STEL, IDLH, LD/LC etc. see Part 6.8, for routes of entry see Part 6.6, for effects of exposure see Part 6.7, for engineering controls see Part 6.12.2 and for health hazards see Part 6.1, all of Chapter-24. For emergency and first aid treatment and antidotes see Chapter-26, for fire and NFPA (National Fire Protection Association of USA) Code see Part 4.4 of Chapter-13, for ventilation see Chapter 10 and for personal protective equipment see Chapter-25. TLV and STEL are given in 2nd Schedule of the Factories Act. LD50 and LC50 are given in 1st Schedule of the MSIHC Rules for the purpose of major accident hazard. LD50 for insecticides are given in Rule 19 of the Insecticide Rules for labelling purpose. Lower these values, higher the toxicity. LD50 up to 200 mg/kg and LC50 up to 10 mg/l can cause major hazard. By local exhaust ventilation toxic gas, dust or vapour must be captured and effective PPE must be worn by the workers. Above STEL, SBA is desirable. 38. Tremcard : Transport Emergency Cards are to be given to the drivers carrying dangerous goods for emergency information which may be needed at any time during journey. The cards contain short information on nature of chemical, hazards involved, protective devices, emergency action for fire, spillage, leakage, first-aid etc.

• Directorate Industrial Safety and Health is a part of Labour and Employment Department, Govt. of Gujarat. Directorate Industrial Safety and Health, Govt. of Gujarat. previously was known as Factory Inspectorate, but after declaration of new designations for Factory Inspectors by state govt; this administration is now Directorate Industrial Safety and Health. It is functioning under direct control of Director Industrial Safety and Health, Gujarat State. For efficient administration and effective control, state is divided in to four administrative regions namely Ahmedabad , Vadodara, Surat and Rajkot. These regions are under control of Jt. Director Industrial Safety and Health for relevant region.The Directorate Industrial Safety and Health looks after the implementation of following statues

• The Factories Act 1948 and Gujarat Factories Rules, 1963
• The Environment Protection Act, 1986
• The Manufacture, Storage and Import of Hazardous Chemical Rules, 1989
• Chemical Accidents (Emergency Planning, Preparedness and Response ) Rules, 1996
• The Building and Other Construction Workers (Regulation of Employment and
   Condition of Service) Act, 1996
• Gujarat Building and Other Construction Workers (Regulation of Employment and
  Condition of Service) Rules-2003
• The Payment of Wages Act, 1936 and Rules there under
• The Maternity Benefit Act, 1961 and Rules there under
• The Gujarat Physically Handicapped Persons (Employment in Factories) Act, 1982
• The Gujarat Payment of Unemployment Allowance to workmen (In Factories) Act,
   1981
• The Cotton Ginning and Pressing Factories Act, 1925

The history of Factories Act is more than 100 years old. First time the Indian Factories Act was enacted in 1881.After independence, 'The Factories Act, 1948' was made applicable in the country mainly to regulate health, safety, welfare and working conditions of Industrial workers. It has been amended from time to time, but the major amendments were enacted in 1976 and in 1987, wherein emphasis has been laid on safety in general and chemical safety in particular. To strengthen safety in chemical factories, Government of Gujarat amended the 'Gujarat Factories Rules, 1963' in February 1995.

The departmental Hierarchy is Director Industrial Safety and Health > Joint Director Industrial Safety and Health >Deputy Director Industrial Safety and Health > Assistant Director Industrial Safety and Health > Industrial Safety and Health Officer
To look after welfare of female workers, Lady Inspector of Factories has also been appointed under the Factories Act, 1948.

All the inspecting officers have been declared as Assistant Public Prosecutors for purpose of Factories Act.The Directorate Industrial Safety and Health, Gujarat State has also been declared authority under certain section of Environment Protection Act, 1986 and Manufacture, Storage, Import of Hazardous Chemicals, Rules, 1989, as amended in 1994.

Under Environment Protection Act, 1986, the Government of India has framed chemical Accidents (Emergency Planning, Preparedness and response) Rules, 1996, where the Inspector of factories performs the duties as member secretary of various crisis groups constituted under these rules through out the state.

The Directorate Industrial Safety and Health officers have also been appointed as inspectors under The Building and Other Construction Workers (Regulation of Employment and Condition of Service) Act, 1996.

Construction sector has huge employment and the newly given responsibility is a real big challenge for the wing. Implementation of the new legislation is recently started.

The Directorate Industrial Safety and Health officers have also been appointed as inspectors under the Payment of Wages Act, 1936, so far as the factories registered under the Factories Act, 1948 are concerned. For effective implementation of the Act, Payment of Wages Inspector is also appointed.

The officers of this wing have also been notified as Inspectors under Maternity Benefit Act, 1961.

The Government of Gujarat has enacted Gujarat physically Handicapped persons (Employment in Factories) Act, 1982. Under this legislation all Inspecting officers under DISH have been appointed as Inspector for implementation of this Act.

The Government of Gujarat has also enacted "The Gujarat Payment of Unemployment Allowances to Workmen (in Factories) Act, 1981". The employer is required to pay 50% wages to workers in the event of power-cut, if he is unable to provide alternative employment to workers within 8 Kms form the normal working place provided that the power cut is notified by Government. This wing also looks after the implementation of this Act.

The Directorate Industrial Safety and Health implements technical in nature, the officers appointed are mostly engineers, qualified in various disciplines of engineering. Looking to major concentration of chemical factories in the state, the Directorate Industrial Safety and Health has constituted a multi-disciplinary specialist cell in each region headed by Joint Director Industrial Safety and Health. Moreover one Assistant Director Industrial Safety and Health (chemical) has been appointed for assisting and advising Chief Inspectors of Factories about hazards and safety in chemical factories.

To assist legal matters, Law officers have been appointed in Ahmedabad and Vadodara Regions.To measure and monitor the ill effects of chemicals, cotton dust, Asbestos dust and Silica dust etc., Industrial Hygiene Laboratory has been established under the Chief Inspector of Factories. It is headed by Dy. Director of occupational health and consists of Medical Inspectors of Factories, Certifying Surgeons and other technical staff.
