Plants face the constant challenge of allocating energy between growth and defense. While growth ensures survival and reproduction, defense protects against harmful bacteria.

Until now, scientists struggled to explain how plants achieve this balance. Researchers at Princeton University recently uncovered new insights into this process, revealing the surprising role of soil bacteria in managing plants’ immune responses.

How soil bacteria help plants

Published in the journal Cell Reports, the study explores how certain soil bacteria impact plant immunity. The bacteria produce enzymes that reduce immune activity in plants, enabling their roots to grow longer.

This discovery sheds light on how plants interact with microbiomes without triggering constant immune responses.

“This is trying to get at a really big biological question where there are not good answers – about how microbiomes interface with host immune systems,” said Jonathan Conway, the study’s senior author and an assistant professor of chemical and biological engineering.

“It’s a small step in the direction of trying to understand how microbes live on hosts – either plants or humans or other animals – all the time and don’t activate our immune responses constantly.”

Balancing health and growth

The team focused on Arabidopsis, a small mustard plant often used in research. They engineered Arabidopsis seedlings with heightened sensitivity to flagellin, a bacterial protein that typically activates immune responses.

On exposure to flagellin, these plants directed energy toward immunity, resulting in stunted root growth.

To identify bacteria that could suppress this immune response, the researchers introduced 165 bacterial species to the seedlings.

Remarkably, 41% of these isolates suppressed the stunted growth response, allowing roots to grow longer. Among these, Dyella japonica emerged as particularly effective.

Enzyme regulates immune system response

The researchers discovered that D. japonica, a soil bacterium, produces an enzyme called subtilase. This enzyme breaks down flagellin, a protein that normally triggers a plant’s immune response.

By degrading flagellin, subtilase prevents the plant’s immune system from activating unnecessarily, enabling the roots to grow without being stunted.

To confirm subtilase’s role, the team used genetic and biochemical techniques. These methods demonstrated that subtilase directly modulates the plant’s immune response, proving its critical function.

Purifying the subtilase enzyme posed significant challenges, as obtaining a pure protein is essential for detailed analysis. A breakthrough came when Todd Naumann, a USDA chemist, suggested purifying the enzyme using yeast cells instead of bacteria.

This alternative approach worked effectively, allowing the researchers to proceed with advanced studies on the enzyme’s properties and functions.

“Now we can do chemistry with it, and we can actually look at this in vitro,” said co-first author Samuel Eastman.

Dual role of soil bacteria

The findings suggest that many soil bacteria may use similar enzymes to influence plant growth and immunity. This raises intriguing questions about the potential benefits for both plants and bacteria.

One theory is that the enzymes prevent pathogens from invading plant roots by disabling their flagella. Alternatively, the enzymes might help pathogens evade detection, potentially increasing the risk of disease.

“So, in that way it could be suppressing pathogens as well as the plant immune system,” Eastman noted. However, he warned of the risks in agricultural applications.

“We don’t want to compromise the immune system, but we also want plants to save that immune response for when it matters.”

Improving crop growth and plant health

The team’s work opens doors to harnessing beneficial bacteria for agriculture while minimizing risks. With further research, these findings could lead to innovative ways to improve crop growth without compromising plant health.

For now, scientists are one step closer to understanding the delicate balance of growth and defense in plants.

The study was a team effort involving nine Princeton researchers, including six undergraduates. Senior thesis projects played a vital role, such as that of Britley Jones from the Class of 2023.

During 2005 to 2021, additional carbon sink of 2.29 billion tonnes of CO2 created through forest and tree cover

Posted On: 02 JAN 2025 4:06PM by PIB Delhi

India’s 4th Biennial Update Report (BUR-4) to the United Nations Framework Convention on Climate Change (UNFCCC) was submitted on 30th December, 2024. The BUR-4 updates the Third National Communication (TNC) and contains the National Greenhouse Gas (GHG) inventory for the year 2020. The report also embodies information on India’s national circumstances, mitigation actions, an analysis of the constraints, gaps, related finance, technology, and capacity-building needs.

In a post on social media, Union Minister for Environment, Forest and Climate Change, Shri Bhupender Yadav, stated that India is leading by example in sustainable growth. These numbers reflect Prime Minister Shri Narendra Modi’s commitment to aligning economic progress with meaningful climate action, he added.

In 2020, India’s total GHG emissions decreased by 7.93 per cent with respect to 2019. The emissions, excluding Land Use, Land-Use Change and Forestry (LULUCF), were 2,959 million tonnes of CO2e and net emissions of 2,437 million tonnes of CO2e with the inclusion of LULUCF. The energy sector contributed the most to overall emissions (75.66 percent), followed by the agriculture (13.72 percent), Industrial Processes and Product Use (8.06 percent), and Waste (2.56 percent). In 2020, India's forest and tree cover, along with other land use, sequestered approximately 522 million tonnes of CO2, equivalent to reducing 22% of the country's total carbon dioxide emissions in 2020.

India’s achievements in respect of the NDC targets:

India has progressively continued decoupling economic growth from GHG emissions. Between 2005 and 2020, India’s emission intensity of Gross Domestic Product (GDP) reduced by 36%.

By October 2024, the share of non-fossil sources in the installed electricity generation capacity was 46.52%. Total installed capacity of renewable power, including large hydropower, is 203.22 GW and cumulative renewable power installed capacity (excluding large hydro projects) has increased 4.5 times from 35 GW in March 2014 to 156.25 GW.

India’s forest and tree cover has consistently increased and currently stands at 25.17% of the total geographical area of the country. During 2005 to 2021, additional carbon sink of 2.29 billion tonnes of CO2 equivalent has been created.

Despite India's very low contribution to historical emissions and the current levels of global emissions, India has taken proactive actions to combat climate change in the context of sustainable development and its developmental aspirations. This is in light of India’s national circumstances, reflecting principles of equity and common but differentiated responsibilities and respective capabilities (CBDR-RC), as enshrined in the UNFCCC and its Paris Agreement.

The potent Synergy between Green Hydrogen & Green Ammonia: A Partnership for a Sustainable Green Economy 

In the quest for sustainable energy solutions, industries worldwide are turning their gaze towards the potent partnership of green hydrogen and green ammonia. As the spectre of climate change looms ever larger, the transition to cleaner energy sources has never been more pressing. Understanding the intricate dance between these two green powerhouses is a must for executives leading the charge in glass & ceramics, concrete production, steelmaking, fertilizers, and other heavy industries. 

Unlocking Synergies: The Green Ammonia + Green Hydrogen Nexus 

While green hydrogen holds immense promise on its own, its synergy with green ammonia unlocks even greater potential. Green ammonia serves as a carrier for hydrogen, offering a means of storing and transporting hydrogen energy efficiently. Companies can circumvent the challenges associated with hydrogen storage and distribution by converting green hydrogen into green ammonia through the Haber-Bosch process. 

At its core, green ammonia is synthesized through the sustainable production of hydrogen via electrolysis, powered by renewable energy sources such as wind or solar. This green variant of ammonia stands in contrast to its conventionally produced counterpart, which relies on fossil fuels and emits significant amounts of carbon dioxide. 

The Potentials of Green Hydrogen 

At the heart of this synergy lies green hydrogen, a clean fuel produced through the electrolysis of water powered by renewable energy sources like wind or solar. Unlike its carbon-intensive counterpart, grey hydrogen, green hydrogen emits zero greenhouse gases during production and combustion, making it a cornerstone of green economy. 

The appeal of green hydrogen lies in its versatility. From fueling transportation to storing renewable energy, its applications span far and wide. But where it truly shines is in the industrial realm. Industries grappling with decarbonization, such as glass & ceramics, concrete production, steelmaking, and fertilizers, stand to reap immense benefits from integrating green hydrogen into their operations. 

The Role of Green Hydrogen and Ammonia in Industrial Processes  

Green ammonia serves as a versatile energy vector, facilitating the integration of renewable hydrogen into existing industrial infrastructure. Its high energy density and ease of handling make it an attractive option for long-term energy storage and transportation. Additionally, green ammonia can serve as a clean fuel for heavy-duty transportation, further reducing reliance on fossil fuels. 

Green ammonia's significance extends beyond its direct applications—it serves as a linchpin for enabling a broader transition to sustainable industrial practices. By acting as a carrier for renewable hydrogen, green ammonia facilitates the efficient storage and transportation of clean energy.  

In a nutshell Green hydrogen can be converted to green ammonia to facilitate its transport and storage. When the time comes Green ammonia can again be transformed into Green hydrogen by industries to be used as a potent fuel for powering kilns and furnaces, offering a sustainable alternative to fossil fuels. 

Green Ammonia as fuel 

Green ammonia can be used as a fuel but with certain considerations and challenges. Ammonia (NH3) is a compound consisting of nitrogen and hydrogen atoms and is commonly used in various industrial applications. As a fuel, ammonia has gained attention due to its potential as a clean energy carrier, particularly for applications where direct electrification or other forms of renewable energy may not be feasible. 

Advantages of Ammonia as a Fuel: 

High Energy Density: Ammonia has a high energy density by volume, making it a potentially efficient fuel for transportation and energy storage applications. 

Carbon-Free Combustion: When burned, ammonia produces only water vapor and nitrogen gas, without emitting carbon dioxide (CO2). This makes it attractive for reducing greenhouse gas emissions, particularly in shipping and heavy-duty transportation sectors. 

Existing Infrastructure: Ammonia already has a well-established infrastructure for production, distribution, and storage, primarily due to its widespread use in the chemical industry. 

Challenges of Using Ammonia as a Fuel: 

Conversion Efficiency: Converting ammonia back into usable energy, whether through combustion in internal combustion engines or through fuel cells, can be less efficient compared to other fuels like hydrogen. 

Safety Concerns: Ammonia is toxic and can be hazardous if mishandled. Safe storage, transportation, and handling procedures are essential for its use as a fuel. 

Emission of Nitrogen Oxides (NOx): While ammonia combustion emits no CO2, it can produce nitrogen oxides (NOx) during combustion, which contributes to air pollution and may require emission control technologies. 

Cost of Production: Green ammonia production methods, such as electrolysis using renewable electricity, may currently be more expensive compared to conventional methods. However, ongoing research and advancements in technology are aimed at reducing production costs. 

Industries that directly benefit from the use of Green Ammonia as a Fuel: 

Green Ammonia

Fertilizer production: Ammonia is a key component of nitrogen-based fertilizers, is traditionally produced via the energy-intensive Haber-Bosch process, which relies on fossil fuels. Green ammonia, synthesized using renewable energy-powered electrolysis, offers a sustainable alternative. By integrating green ammonia into fertilizer production, agricultural industries can mitigate emissions and foster sustainable food systems.  

Heavy Transportation: Ammonia can be used as a fuel in internal combustion engines, fuel cells, or as a feedstock for hydrogen production It is particularly suitable for long-haul transport modes such as shipping and trucking due to dilution of the costs in large-scale operations. 

Power Generation: Ammonia can be burned directly in gas turbines or used in fuel cells to generate electricity, offering a potential avenue for decentralized power generation, especially in areas with limited access to conventional energy sources. 

Industries that can benefit indirectly from Green Ammonia: 

The industries on the list below can rely on ammonia for the storage and transportation of energy but not directly as fuel. Nevertheless, the benefits exist and can help with the decarbonization of such industries. 

Glass & Ceramics: 

Glass and ceramics production is notoriously energy-intensive, with traditional furnaces guzzling copious amounts of fossil fuels. By harnessing green hydrogen as a clean heat source, manufacturers can slash carbon emissions while maintaining production efficiency. Moreover, green hydrogen-derived electricity can power kilns and furnaces, offering a dual-pronged approach to decarbonization.  

Concrete Production: 

The cement industry, a cornerstone of modern infrastructure, is responsible for a significant chunk of global CO2 emissions. Green hydrogen presents a game-changing alternative to the fossil fuels traditionally used in cement kilns. Concrete manufacturers can drastically reduce their carbon footprint without compromising structural integrity by leveraging green ammonia combustion or incorporating green hydrogen into the cement production process. 

Steelmaking: 

Steel, the backbone of countless industries, is notorious for its carbon-intensive production process. Green hydrogen offers a lifeline to steelmakers grappling with decarbonization mandates. Through direct reduction processes or as a reducing agent in blast furnaces, hydrogen holds the key to unlocking a low-carbon future for the steel industry.  

Main Takeaways: 

The convergence of green hydrogen and green ammonia stands for an important moment in our journey towards sustainability. Executives across industries are tasked with embracing this responsibility, recognizing the transformative potential inherent in these technologies. Together, green hydrogen and green ammonia form a powerful alliance, paving the way towards a future where sustainability is not just an aspiration but a tangible reality. By harnessing the synergies between these two compounds, industries can unlock unprecedented opportunities for innovation and growth. The journey towards sustainability may be challenging, but with green hydrogen and green ammonia, we can navigate towards a future where economic prosperity and environmental stewardship go hand in hand. 

Atterberg limits are a set of measures used to determine the consistency and nature of fine-grained soils, such as clay and silt. These limits are based on specific moisture content values, and can be used to distinguish between different types of clay and silt

 Atterberg limits are a set of measures used to determine the consistency and nature of fine-grained soils, such as clay and silt. These limits are based on specific moisture content values, and can be used to distinguish between different types of clay and silt. 

The Atterberg limits include: 

Liquid limit (LL)

The maximum amount of water a soil can contain before it turns into mud

Plastic limit (PL)

The minimum amount of water a soil can contain before it behaves in a plastic manner, meaning it can be molded

Shrinkage limit (SL)

The water content at which further loss of moisture will not cause any more volume reduction

Plasticity index (PI)

The range of moisture contents at which the soil remains plastic, calculated by subtracting the plastic limit from the liquid limit (PI = LL - PL)

Atterberg limits are used to classify fine-grained soils, and can also be used to predict the engineering properties of these soils. For example, the plasticity index is a useful indicator of a soil's potential to resist liquefaction. 

The Atterberg limits were developed by Albert Atterberg in 1910 and refined by Arthur Casagrande in 1927.

Geotechnical investigation of soil is a process that involves collecting and analyzing information about the subsurface conditions of a site to determine the geomaterial parameters needed for design

  Geotechnical investigation of soil is a process that involves collecting and analyzing information about the subsurface conditions of a site to determine the geomaterial parameters needed for design. It is a crucial step in the construction process, as it helps to understand the soil conditions that will affect the design and construction of a structure. 

Geotechnical investigations are necessary for any type of construction project, from a single house to a large warehouse, bridge, or infrastructure project. The information gathered from these investigations helps to determine: The type of foundation required, How the structure will be built, and The cost of the construction project. 

Geotechnical investigations typically include: 

Surface exploration

This can involve geologic mapping, photogrammetry, or simply observing the physical conditions of the site.

Subsurface exploration

This can involve soil sampling, test pits, trenching, borings, and in situ tests.

Laboratory tests

These tests are performed on the soil samples retrieved during subsurface exploration.

The information gathered from a geotechnical investigation helps design and structural engineers to recommend design criteria for the project. 

Cross-hole tests, such as cross-hole seismic and cross-hole sonic logging, can be beneficial for assessing soil and rock properties:

 Cross-hole tests, such as cross-hole seismic and cross-hole sonic logging, can be beneficial for assessing soil and rock properties: 

Cross-hole seismic tests

These tests can help identify hidden layer velocity anomalies that are not detectable using surface methods. They can also help determine the dynamic properties of soil and rock, which can be used for earthquake design, liquefaction potential studies, and more. 

Cross-hole sonic logging (CSL)

CSL is a reliable technique for assessing the structural integrity of deep foundations. It can help identify potential shaft anomalies, and can be used to collect data for engineering analysis. CSL test results are relatively easy to interpret, and are not affected by skin friction, soil stiffness, or damping characteristics. 

Ground improvement

Cross-hole geophysical testing can show that the ground has been improved in cases where cone penetration tests are unable to demonstrate the same level of improvement. 

Design verification

Cross-hole geophysical testing can be used to verify variations of commonly accepted designs, which can save construction time and costs.

Districts with excess nitrates in groundwater at seven-year high

Excess nitrates are a health hazard, especially for young children; found in groundwater largely due to subsidised fertilizer use; the situation is worsening in central and southern India with highest levels in Rajasthan, Karnataka, T.N.

There are 440 districts with excessive nitrates in their groundwater as of 2023, an increase from 359 such districts in 2017, according to a report by the Central Groundwater Board (CGWB) on Wednesday (January 1, 2025). This is a health hazard, particularly for young children, and a source of environmental toxicity.

The data suggests that about 56% of India’s districts have excessive nitrates — defined as more than 45 mg per litre — in their groundwater, largely due to the use of subsidised, nitrogenous, synthetic fertilizer, a key input for farming.

Of the 15,239 groundwater samples collected from across the country for testing, 19.8% had nitrates or nitrogen compounds above safe limits, according to the report by the CGWB, which comes under the ambit of the Jal Shakti Ministry. This proportion has not shifted much since 2017. In the 13,028 samples analysed in 2017, 21.6% had excessive nitrates.

Concerns in south, central India

Rajasthan, Karnataka, and Tamil Nadu reported the maximum nitrate contamination problem, with 49%, 48%, and 37% of their tested samples respectively reporting numbers beyond the safe limit.

Rajasthan, Madhya Pradesh, and Gujarat have a long-standing nitrate problem with relative levels fairly constant since 2017, the report says. However, regions in central and southern India are reporting an increasing trend, provoking worry. “Maharashtra (35.74%), Telangana (27.48%), Andhra Pradesh (23.5%) and Madhya Pradesh (22.58%) also show notable levels of nitrate contamination, pointing towards growing concern in central and southern regions of India,” the report notes.

Monsoon rainfall tends to increase nitrate levels, with 30.77% of samples contaminated in the pre-monsoon period compared to 32.66% after the rainy season.

Uranium contamination

Other major chemical contaminants affecting groundwater quality are fluoride and uranium. Fluoride concentrations exceeding the permissible limit are “a major concern” in Rajasthan, Haryana, Karnataka, Andhra Pradesh, and Telangana. Rajasthan and Punjab reported the highest number of samples with uranium concentration exceeding 100 ppb (parts per billion).

Anything over 30 ppb of uranium is considered unsafe and several of these samples were predominant in regions of Rajasthan, Gujarat, Haryana, Punjab, Tamil Nadu, Andhra Pradesh, and Karnataka, where more groundwater is being over-exploited, with more water is being drawn out than is being replenished by rains or other means. “This overlap points to the exacerbating effect of overexploitation and deepening water levels on uranium contamination in these regions,” the report adds.

In an accompanying report on the availability of groundwater across India, the CGWB estimates that on the whole, the degree of groundwater extraction across the country is 60.4%, roughly the same as it has been since 2009, when measurements began biennially (and annually since 2022). About 73% of the blocks analysed for groundwater levels are in the ‘safe’ zone, meaning that they are replenished enough to compensate for the water drawn out. This is a sharp rise from the 67.4% in 2022. However, there were 343 fewer blocks analysed for the 2024 assessment, compared to 2022.

Reforms and Initiatives

Rights of Consumers Rules: Electricity Rules were notified in February 2024 to empower electricity consumers. This framework lays down their rights and provides mechanisms to enforce them. The rules ensure timely access to services such as new connections, grievance redressal, and billing transparency while facilitating rooftop solar adoption and electric vehicle (EV) integration. Key provisions include:

Simplifying rooftop solar installation processes with exemptions from technical

feasibility study for systems up to 10 kW.

Allowing separate connections for EV charging stations to promote clean

mobility.

 Reducing timelines for new connections: 3 days in metros, 7 days in municipal areas, and 15 days in rural regions (30 days for hilly terrain).

Mandating consumer rights for separate metering and billing in residential

colonies, enhancing transparency and fairness.

Introducing mandatory check meters to verify consumption in case of

complaints.

Additional Surcharge elimination: The Electricity Rules, 2005 have been amended in 2024 to rationalise open access charges. New rules now allow large consumers (open access consumers) to buy electricity from the cheapest sources across India, not just from their local Distribution Licensee. Some State regulators charge large consumers heavily to buy electricity from other sources. In an effort to reduce these charges, the additional surcharge levied is now being gradually reduced and will be completely removed within four years. Importantly, large consumers who have never bought electricity from their distribution licensee are not required to pay additional surcharge.

Computer Security Incident Response Team – Power (CSIRT–Power): Union Minister for Power inaugurated Computer Security Incident Response Team – Power (CSIRT–Power) facility in September, 2024. Equipped with advanced infrastructure, cutting-edge cybersecurity tools, and key resources, CSIRT-Power is now well-prepared to tackle emerging cyber threats.

NFPA 30: Flammable and Combustible Liquids Code

 NFPA 30: Flammable and Combustible Liquids Code 

In industries handling flammable and combustible liquids, safety is a top priority. The NFPA 30 standard, developed by the National Fire Protection Association (NFPA), provides comprehensive guidelines to ensure safe storage, handling, and usage of these hazardous materials.

What is NFPA 30?

NFPA 30, also known as the Flammable and Combustible Liquids Code, is a globally recognized standard that helps minimize fire and explosion risks. It’s essential for industries such as:

Oil and Gas

Chemical Manufacturing

Storage Facilities

Pharmaceuticals

This code is the cornerstone for ensuring workplace safety and regulatory compliance.

 Key Highlights of NFPA 3

1️⃣ Liquid Classification

NFPA 30 divides liquids into categories based on flashpoints and boiling points:

Flammable Liquids: Flashpoint below 100°F (37.8°C).

Combustible Liquids: Flashpoint at or above 100°F.

Understanding these classifications is vital for determining appropriate storage and handling methods.

2️⃣ Storage Requirements

Approved Containers: Specifies the use of certified containers and tanks.

Storage Cabinets: Requires fire-resistant cabinets for certain quantities.

Safe Distances: Outlines minimum separation between storage areas and occupied spaces.

3️⃣ Handling Best Practices

Use bonding and grounding during liquid transfers to prevent static discharge.

Ensure proper ventilation in areas with potential vapor accumulation.

Operate only explosion-proof equipment near flammable substances.

4️⃣ Fire Protection Systems

Sprinklers and Foam Systems: Essential for fire suppression in high-risk areas.

Emergency Plans: Mandates detailed procedures for fire response and evacuation.

 Why is NFPA 30 Important?

Reduces Risk: Prevents fires, explosions, and workplace accidents.

Ensures Compliance: Meets local and international safety standards.

Protects Investments: Safeguards lives, assets, and the environment.

Ventilation Safety for Gas Cylinder and Chemical Storage: A Critical Safety Measure★

 ★Ventilation Safety for Gas Cylinder and Chemical Storage: A Critical Safety Measure★ 

1. Prevents Accumulation of Dangerous Gases: Gas cylinders, particularly those containing flammable, toxic, or reactive gases, can leak and release hazardous vapors. Without proper ventilation, these gases can accumulate, leading to toxic exposure or even explosions.

2. Minimizes Fire and Explosion Risks: Many gases, such as propane, acetylene, and hydrogen, are highly flammable. Inadequate ventilation can lead to the build-up of an explosive atmosphere in storage areas, which can trigger fires or explosions if an ignition source is present.

3. Ensures Worker Health and Safety: Chemical storage areas can also release vapors, aerosols, or fumes from volatile chemicals. If the air quality isn’t adequately managed through ventilation, workers could face long-term health issues, including respiratory problems or chemical poisoning.

Best Practices for Ventilation Safety in Gas Cylinder and Chemical Storage

1. Install Local Exhaust Ventilation (LEV): Local exhaust systems should be installed to remove hazardous vapors and gases directly from the source, such as near gas cylinder storage areas or chemical transfer points. LEV systems are more effective than general room ventilation at maintaining air quality.

2. Ensure Adequate Airflow: Gas cylinders and chemicals should be stored in well-ventilated rooms or outdoor areas with sufficient airflow to disperse any harmful vapors. Mechanical fans or natural ventilation systems (windows, vents) can help ensure a constant flow of fresh air.

3. Designated Storage Areas for Gas Cylinders: Gas cylinders should be stored in a designated, ventilated space separate from other chemicals, particularly flammable or reactive materials. These areas should be equipped with explosion-proof ventilation systems and away from heat sources.

4. Proper Ventilation Ductwork: Ensure that ventilation ductwork is designed to handle the specific types of gases or chemicals stored. Ducts should be made from materials that are resistant to corrosion or damage from chemical exposure, and they should be regularly cleaned and maintained.

5. Continuous Monitoring of Air Quality: Install gas detectors and air quality monitoring systems in chemical and gas cylinder storage areas. These systems should be capable of detecting dangerous gas concentrations, triggering alarms, and activating ventilation systems if necessary.

7. Explosion-Proof Equipment: In areas where flammable gases or chemicals are stored, ensure all ventilation equipment (fans, lights, electrical systems) is explosion-proof. This reduces the risk of ignition in volatile environments.

8. Regular Inspections and Maintenance: Ventilation systems should be inspected regularly to ensure they are functioning properly. This includes checking air filters, exhaust fans, and ensuring there are no blockages or leaks in the ductwork.

9. Proper Venting of Storage Containers:

Hazard vs Risk

 HAZARD🔥

A hazard is a potential source of harm, such as stairs or a chemical. Hazards can be physical, biological, chemical, or ergonomic. They can exist regardless of exposure or vulnerability.

 

RISK☄️

Risk is the likelihood of a hazard causing harm, and how serious that harm could be. Risk considers both the probability and severity of harm. Risks can take many forms, such as physical risks like wet floors or reputational risks like bad reviews.

Understanding both hazards and risks is important for effective health and safety management. Risk assessments are scientific analyses that determine the level of exposure to a hazard that is safe.
