The term "EHS" often arises in the context of Environmental & Water Treatment, representing a critical interplay between extremely hazardous substances and environmental health and safety. Understanding both aspects is paramount to ensure safe and sustainable operations within this industry.
1. Extremely Hazardous Substance (EHS):
An extremely hazardous substance (EHS), as defined by the U.S. Environmental Protection Agency (EPA), is a chemical that poses a significant risk to human health and the environment. These substances can be:
Common examples of EHS in water treatment include:
2. Environmental Health and Safety (EHS):
EHS in the context of environmental & water treatment refers to a comprehensive approach that prioritizes:
EHS in action:
EHS principles are implemented through various measures, including:
The importance of EHS:
EHS is crucial for environmental & water treatment facilities for several reasons:
Conclusion:
EHS plays a critical role in ensuring the responsible and safe operation of environmental & water treatment facilities. By prioritizing worker safety, environmental protection, and community health, the industry can contribute to a healthier environment and a sustainable future.

Scenario: You are the EHS manager at a water treatment plant. A recent inspection revealed a leak in a pipe containing sodium hypochlorite.
Task:
**1. Immediate Risks:** * **Worker Safety:** Sodium hypochlorite is a corrosive and toxic substance, posing risks of skin burns, respiratory irritation, and eye damage to workers. * **Environmental Contamination:** The leak could contaminate surrounding soil and water bodies, affecting the ecosystem and downstream water users. * **Community Health:** The leak could pose a risk to the health of nearby residents, particularly if they are exposed to the fumes or runoff. **2. Addressing the Situation:** * **Isolate the Leak:** Immediately isolate the leaking pipe by shutting off the valve or using other appropriate methods to contain the leak. * **Evacuate Personnel:** Evacuate all personnel from the immediate vicinity of the leak and establish a safe perimeter. * **Activate Emergency Response:** Call the local emergency services (fire department, hazardous materials team) and provide them with all necessary information about the leak and the substance involved. * **Use Personal Protective Equipment (PPE):** Ensure all personnel responding to the leak are wearing appropriate PPE, including respirators, gloves, and protective clothing. * **Contain the Spill:** Use absorbent materials to contain the spilled sodium hypochlorite and prevent it from spreading further. * **Neutralize the Spill:** If possible, use appropriate neutralizers to safely neutralize the sodium hypochlorite. * **Ventilate the Area:** Ventilate the affected area to remove any hazardous fumes. * **Monitor and Assess:** Monitor the situation closely and assess the extent of the leak and potential impact on the environment and community. **3. Documentation and Corrective Actions:** * **Incident Report:** Prepare a detailed incident report, documenting the date, time, location, cause of the leak, response actions taken, personnel involved, and any injuries or environmental damage. * **Corrective Actions:** Identify the root cause of the leak and implement corrective actions to prevent similar incidents from occurring in the future. This could involve replacing the damaged pipe, improving maintenance procedures, or providing additional training for personnel. * **Communication:** Communicate the incident and corrective actions taken to all relevant parties, including employees, management, regulatory agencies, and the local community.
