 A very important subject, Lockout Tagout - LOTO system.

What is the lotto system?

A Lockout Tagout system is an essential security measure aimed at protecting workers during equipment maintenance or repairing from unexpected power emissions. It involves turning off and isolating power sources and securing equipment using locks and warning signs to ensure that the equipment is not operating until the work is completed.

Regime goals:

1. Protecting lives: Prevent accidents resulting from sudden turn-on of equipment.

2. Hazardous Energy Control: Securing hazardous energy sources (electricity, air pressure, heat, chemicals).

3. Everyone's commitment to safety: Fostering a culture of shared responsibility in the workplace.

---

The ingredients of the LOTTO system:

1. Lock: A physical device that prevents equipment from operating.

2. Tag: A clear alert indicates that the stomach is locked and should not be turned on, and the name of the person responsible for the lock is written on it.

3. Sources of energy: They can be electrical, hydraulic, mechanical, or chemical.

Steps for applying LOTO system professionally:

1. Getting ready for work:

Equipment Identification: Identify the equipment that will be maintained and the associated power sources.

Recognizing Risks: Understand the nature of energy that can pose a hazard (electricity, pressure, heat).

WORKER NOTICE: Make sure all staff are aware that the equipment will be isolated.

2. Turn off equipment:

Stop the stomach the right way (pause button or detach the circle).

3. Isolating power sources:

Disconnect all power sources, such as circuit breakers or valves.

Make sure you cut off all power calls.

4. Securing the locks and tags:

Installing the locks: Place the locks on each power source to secure it.

Tagging: Add the warning signs written on it:

Name of the worker in charge.

The oath.

Date and time of operation.

5. Unloading Stored Energy:

Be sure to drain all remaining energy in the equipment (such as hydraulic pressure release or static discharge).

6. Isolation check:

SAFETY TEST: Try to turn on the stomach to make sure it is completely isolated.

Check that energy doesn't come back in an unexpected way.

7. Carrying out the work:

Maintain or repair the stomach while ensuring the system stays in isolation.

8. Restarting the equipment:

After finishing work done:

Lock and tag removal by responsible person only.

Checking over equipment and making sure it’s ready to run.

Notifying all workers that the equipment is safe to operate.

---

The importance of LOTO practical training:

1. A simulation of realistic scenarios:

Training workers on isolation steps in a real work environment.

2. Boosting Commitment :

Teaching workers their responsibilities to ensure system is not overrun.

3. Limit of accidents:

Preventing injuries from inadvertent operating.

---

Tips for applying LOTO efficiently:

Conduct a periodical inspection: Ensure employees are complying with LOTO.

Using high-quality equipment: such as locks and labels, that can't be easily broken.

Documentation: Record each step of the action steps to ensure transparency and accountability.

A message of awareness:

“Lockout Tagout is not just a safety measure, it’s a commitment to protecting lives and ensuring a secure working environment. Adherence to every step protects the staff from irreparable dangers. "

The chronology of safety in India primarily revolves around the establishment of the National Safety Council in 1966

National Safety Day/Week (4-10 March)

Background

The National Safety Day/Safety Week Campaign being spearheaded by the Council since 1971 to mark its Foundation Day (4th March) has significantly contributed in spreading safety awareness in all sectors. The campaign is comprehensive, general and flexible with an appeal to the participating organisations to develop specific activities as per their safety requirements.

Objectives

to take Safety, Health and Environment (SHE) movement to different parts of the country.

to achieve participation of major players in different industrial sectors at different levels.

to promote use of participative approach by employers by involving their employees in SHE activities.

to promote development of need-based activities, self-compliance with statutory requirements and professional SHE management systems at work places.

to bring into the fold of voluntary SHE movement sectors, which have not so far been statutorily covered.

to remind employers, employees and others concerned of their responsibility in making the workplace safer.

In summary, the above objectives are part of an overall goal of creating and strengthening SHE culture in workplace and integrating the same with the 

work culture.

The chronology of safety in India primarily revolves around the establishment of the National Safety Council in 1966, which led to the official observance of "National Safety Day" on March 4th, 1972; however, significant earlier legislation like the Factories Act of 1948 marked the initial focus on worker safety in post-independence India, with further developments addressing environmental and industrial safety concerns throughout the decades. 

Key points in the timeline:

Early 1800s:

During British rule, initial concerns regarding worker safety in factories arose, leading to reports like the one by Major Moore highlighting issues like long working hours and child labor in the Bombay cotton mills. 

1875:

A Royal Commission was established by the Bombay government to investigate working conditions in textile mills and propose regulations. 

1881:

The first Indian Factories Act was enacted, introducing limited protection for workers, including restrictions on child labor and working hours. 

1948:

The Factories Act of 1948 was passed in post-independence India, considered the first major legislation directly addressing worker health and safety in factories. 

1966:

The National Safety Council (NSC) was established by the Indian government as a self-financing, non-profit organization aimed at promoting safety practices. 

1972:

March 4th was declared as "National Safety Day" marking the foundation day of the NSC, initiating a nationwide safety awareness campaign. 

1986:

The Environment Protection Act was enacted in response to major industrial disasters, further emphasizing environmental safety concerns. 

Present Day:

The National Safety Council continues to lead initiatives to promote safety awareness across various sectors in India, focusing on workplace safety, road safety, and environmental protection.

Industry-wide adoption of Circular Approaches is critical to driving Sustainable Growth and Resource Efficiency: Shri Bhupender Yadav

Four Key Strategies for a Successful Circular Economy highlighted - Redesigning Products for Circularity; Investment in Advanced Recycling Technologies; Strengthening Supply Chain Collaboration; Consumer Awareness and Behavioral Change

Posted On: 18 FEB 2025 3:43PM by PIB Delhi

Union Minister for Environment, Forest and Climate Change, Shri Bhupender Yadav today inaugurated a day-long conclave organized by the Recycling and Environment Industry Association of India (REIAI), on ‘Waste Recycling & Climate Change 2025’.

Addressing the inaugural session, the Union Minister stated, “India generates around 62 million tonnes of waste annually, with plastic, electronic, and hazardous waste growing rapidly. The traditional linear economic model of take, make, and dispose is no longer sustainable. The increasing pressure on landfills, depletion of natural resources, and environmental damage from unchecked waste disposal require urgent action. The circular economy is not just an alternative; it is essential. It marks a fundamental shift in how we produce, consume, and manage materials”. A well-functioning circular economy not only conserves natural resources but also fosters industrial innovation, economic competitiveness, and job creation, he stated.

Shri Yadav said that under the visionary leadership of Prime Minister Shri Narendra Modi, India is shifting from waste management to harnessing the economic potential of recycling through waste to wealth initiative. “The circular economy has a major role in the future including reducing, reusing, and recycling at every stage, from product design to end-of-life management. Waste should not be treated as a burden but as a resource. Adopting sustainable practices is crucial for achieving economic resilience, environmental sustainability, and social security”, he added.

The Minister further stated that by the year 2050 India’s circular economy is expected to have a market value of $2 trillion and create 10 million jobs. It a big opportunity for start-ups and new recycled product developers. It is important to align this growth with environmental sustainability, drawing inspiration from nature's efficient recycling systems as nobody recycles like Nature, he added.

Shri Yadav urged the recycling industry in the country to develop and adopt newer innovative technologies for reducing dependence on natural resources as well as cutting down imports of critical minerals needed for economic growth. “Adopting circular economy principles can bring tremendous economic benefits. This shift towards resource efficiency aligns seamlessly with our national vision of Atmanirbhar Bharat, enhancing the competitiveness of Indian industries in global markets”, the Minister added.

The Minister informed that the Ministry has been instrumental in formulating policies and regulations, including Extended Producer Responsibility (EPR) frameworks, that incentivize recyclers and integrate the informal sector into formal recycling systems. These initiatives aim to streamline waste management and promote eco-friendly production across industries. The Ministry has notified a number of market-based Extended Producer Responsibility (EPR) Regulations, including those on e-waste, end-of-life vehicles, plastic packaging, waste tyres, waste batteries, used oil. The revenue earned by registered recyclers from sale of EPR certificates is additional profit earned over and above the profit generated from the sale of recycled product, he added.

Shri Yadav said that the government has laid down the policies but Industry-wide adoption of circular approaches is critical to driving sustainable growth and resource efficiency. The Minister highlighted 4 key strategies in this direction:

Redesigning Products for Circularity: Companies must move beyond single-use models and design products for recyclability. The integration of biodegradable, reusable, and modular components will help extend product life cycles and reduce waste.

Investment in Advanced Recycling Technologies: Adoption of emerging technologies can transform waste management systems, thereby improving recovery rates.

Strengthening Supply Chain Collaboration: Businesses need to collaborate across the value chain to optimize resource utilization, create closed-loop production systems, and build markets for secondary raw materials.

Consumer Awareness and Behavioural Change: Circularity requires active consumer participation. Industries must invest in campaigns to engage consumers, incentivize recycling, and promote sustainable consumption behaviours.

Dr Amandeep Garg, Additional Secretary, Ministry of Environment, Forest and Climate Change and Chairman, Central Pollution Control Board (CPCB) said, “There is a huge gap and huge potential to work towards waste recycling system, as the role of recycling industry is important cut imports of various critical products needed for economic growth”. Corporate houses should lead the transition to a circular economy by incorporating recyclable designs, promoting sustainability in dealership operations, and enhancing consumer awareness, he added.

The event witnessed the presence of Dr. Ashok Kumar, President, Recycling and Environment Industry Association of India and subject experts from the industry and about 200 delegates environmental scientists, waste management professionals and policymakers.

Five Common Problems with Raw Water Treatment and How to Avoid Them

 Five Common Problems with Raw Water Treatment and How to Avoid Them

Five Common Problems with Raw Water Treatment and How to Avoid Them

For industrial companies treating a raw water source for its processes, there are several issues that can surface during treatment that we see on a regular basis. We’ve broken out the five most common problems with raw water treatment and how to avoid them below.

Whether you’re designing a new plant or updating existing equipment, avoiding these five common raw water treatment problems might help you operate your process more efficiently down the line, so they’re important to keep in mind and plan for ahead of time, if possible:

1. Variation in turbidity

When plants begin to experience a variation in turbidity—the cloudiness of water due to the presence of a large number of particles—it can have negative effects on the quality of the process and effluent from the plant. It’s helpful to have a consistent year’s worth of data to evaluate the turbidity levels coming into the plant from season to season prior to designing the system.

When the plant is designed around the seasonal turbidity flow without taking into consideration any of the changes it might see—if the turbidity increase without the plant being ready for this change—there are several problems that might occur.

When the turbidity is too high for the plant to remove it efficiently, it often carries over to production and can be present in your discharge, contaminating your process and causing fines when local discharge regulations are not met.

Another issue we see when turbidity levels vary, is the amount of sludge that’s generated from treating the turbidity. Oftentimes secondary sludge systems can’t handle the load, and therefore the sludge backs up in the clarifier and shuts down the pretreatment system.

The best way to combat this problem is to design a slightly oversized treatment system for turbidity, anticipating that variations will occur. It’s also beneficial to design a recycle system so if the water doesn’t meet the quality requirements as it moves through the process, it can be recycled through and retreated more thoroughly.

Another way to prepare for varying turbidity is to include variable controls on your chemical feedsystems so you can adjust chemical feed rates. You can also oversize the sludge handling system so when you pump out the sludge in the clarifiers filters, you have a sludge handling system that, if the turbidity does fluctuate, has the ability to manage it.

2. Variation in flow

Many times, industrial companies make educated guesses as to what they think their flow rates are going to be. If an industrial facility is not equipped to handle these variations, they’ll likely experience upsets to the system that will carry turbidity over and plug any downstream filters.

Understanding what peak demand is and using holding tanks to try to buffer out the peak demands is one way to prepare for flow variations. Typically, you want to design the system with an excess flow buffering/holding capacity so you can run your plant as consistently as possible and then use the holding tanks downstream to handle surges in production needs.

Another thing you can do is put variable controls on your chemical feed systems, so as your flow changes, your chemical feeders can ramp up and ramp down to handle it.

With a combination of variable flows on feed treatment equipment and storage on peak demands, you can get your system to balance out more easily and increase functionality. If you don’t have the ability to automate chemicals, you will need to test more often. You can try to run your plant at a consistent flow rate to avoid these upsets and turbidity issues.

Raw water treatment plants do not handle variations in flow well, so it’s helpful to design the system with this in mind from the start.

3. Changing feed chemistry

Many surface and well waters have seasonal variations in water chemistry. Industrial plants need to be very careful in the design of any raw water treatment systems to be large enough to handle these changes.

Let’s say, for example, you have a problem with raw water iron or silica and it changes seasonally. If you haven’t designed your clarifiers large enough to get the proper retention times and you haven’t designed your feed systems large enough to handle the increased load, you’ll get carryover with either silica and/or iron into the downstream equipment where they cause all sorts of problems such as scaling and fouling.

Secondarily, if you don’t anticipate the higher seasonal loads of iron and silica and try to precipitate it out, you may then have particulate carryover to your sludge handling systems, causing them to fail.

All in all, it’s very important to understand the variations of the contaminants feed water chemistry and design a system accordingly. Physical chemical processes to remove the iron and silica is typically an oxidation chemical (such as oxygen) and an aluminum-based coagulant such as alum that will precipitate out the iron and silica and allow them to settle so they can be removed in a clarification filtration system.

If you don’t have a chemical feeder size large enough, you may get carryover of iron and silica. Or if you’re able to precipitate higher, unanticipated volumes of iron and silica, your underflow handling systems such as your sludge thickening and filter pressing operations may not be able to handle the increased amount of sludge.

4. Being unaware of updates/changes to quality requirements

When you design a plant for a certain process and to make sure you meet stringent requirements, sometimes you might find out later you need to adapt your equipment to account for recent changes in regulations. This is a common occurrence that sometimes happens after plants have been installed for years. The plant may be running well and designed to deliver a certain kind of effluent quality, and then one day the standards of the quality requirements become more stringent and the plant no longer meets the requirements at the facility.

As an example, let’s say you are feeding water to a low-pressure boiler and you put in a bigger boiler that runs at a higher pressure. Depending on the requirements of the new boiler, the quality of the feed water to the boiler might no longer be adequate. You might need to ensure the feed water is a better quality and add ancillary equipment to the system.

For this reason, plants should be designed with some forward thinking in mind of what might be anticipated. It is also helpful to plant for expansion and quality improvement and allow space in the plant for adding additional equipment to handle changes in quality requirements.

5. Secondary waste

One of the biggest mistakes made in designing raw water treatment plants is not looking carefully at the secondary waste generated by the process.

Here are some safety considerations for demineralized water (DM water): 

Safety data sheet

Only trained personnel should use DM water. Follow the label warnings, even after the container is empty, as empty containers may still contain product residue. 

Storage

Store DM water in a closed original container in a cool, dry place away from direct sunlight and heat. The ideal temperature for storage is between 15°C and 25°C. 

Hazardous reactions

Avoid exposing DM water to high temperatures or direct sunlight, and avoid freezing it. 

Transport

DM water is not covered by international regulations on the transport of dangerous goods. It does not require a transport warning sign. 

Toxicity

DM water is non-hazardous and non-corrosive to skin. It is pure water and is not toxic to human health during normal use, unless it has been contaminated with other hazardous materials. 

DM water is produced by removing minerals and most ions from water through a purification process. It has a neutral pH, typically ranging from 6.5 to 7.5. It has low conductivity, usually between 1 and 5 µS/cm. 

             

De-mineralization plant is employed for removal of minerals or dissolved salts from the water. Salts on dissolving dissociate into electrically charged particles called ions: for example common salt will be split into sodium ion (a positively charged ion or cation) and chloride (a negatively charged ion or an anion). If such a solution is brought into contact with a suitable ion exchange material (called resin), some ions from the solution are taken up by the resin and an equivalent number are transferred from the resin to the solution. Ion exchange is thus a reversible interchange of ions between a liquid and a solid.

A simple Demineralization Plant consists of two beds of chemically treated resin beads operating in series. The first column- cation exchanger- converts the dissolved solids in the raw water to the equivalent acids; these acids are removed as the water passes through the second column- anion exchanger. The final product from this process consists essentially of pure water. When exhausted, the cation exchange resin is regenerated with acid and the anion exchange resin with alkali.
