https://claude.ai/share/ec4e3048-b64d... 200 Safety Questions and Answers for EHS Interviews Environmental Safety (40 Questions) 1. What is environmental health and safety (EHS)? EHS is a discipline that focuses on protecting human health and the environment by identifying, assessing, and controlling workplace hazards and environmental impacts. 2. What are the main components of environmental management? The main components include pollution prevention, waste management, resource conservation, regulatory compliance, and environmental monitoring. 3. What is a Material Safety Data Sheet (MSDS)? An MSDS, now called Safety Data Sheet (SDS), is a document that provides information about the properties, hazards, handling, storage, and emergency measures for chemical substances. 4. What are the key elements of ISO 14001? ISO 14001 includes environmental policy, planning, implementation, checking and corrective action, and management review for environmental management systems. 5. What is the difference between hazardous and non-hazardous waste? Hazardous waste exhibits characteristics like ignitability, corrosivity, reactivity, or toxicity that pose risks to health or environment, while non-hazardous waste does not. 6. What is the purpose of an environmental impact assessment (EIA)? An EIA evaluates the potential environmental effects of a proposed project or development before it is carried out. 7. What are the main air pollutants regulated by environmental agencies? Major pollutants include particulate matter, sulfur dioxide, nitrogen oxides, carbon monoxide, ozone, and lead. 8. What is the hierarchy of waste management? The hierarchy is: prevention, minimization, reuse, recycling, energy recovery, and disposal as the last option. 9. What is groundwater contamination? Groundwater contamination occurs when pollutants like chemicals, bacteria, or other harmful substances infiltrate underground water sources. 10. What are greenhouse gases? Greenhouse gases include carbon dioxide, methane, nitrous oxide, and fluorinated gases that trap heat in the atmosphere and contribute to climate change. 11. What is a spill response plan? A spill response plan outlines procedures and responsibilities for containing, cleaning up, and reporting hazardous material spills. 12. What is the purpose of environmental monitoring? Environmental monitoring tracks pollution levels, compliance with regulations, and the effectiveness of control measures over time. 13. What is secondary containment? Secondary containment is a backup system designed to contain spills or leaks from primary storage containers, typically required for hazardous materials. 14. What are VOCs? Volatile Organic Compounds (VOCs) are carbon-containing chemicals that easily evaporate at room temperature and can cause health and environmental problems. 15. What is the Clean Air Act? The Clean Air Act is legislation that regulates air emissions from stationary and mobile sources to protect public health and the environment. 16. What is wastewater treatment? Wastewater treatment removes contaminants from water before it is released back into the environment or reused. 17. What is environmental auditing? Environmental auditing is a systematic evaluation of an organization's environmental performance, compliance, and management systems. 18. What is the ozone layer and why is it important? The ozone layer is a region of Earth's stratosphere that absorbs most of the sun's harmful ultraviolet radiation, protecting life on Earth. 19. What is a carbon footprint? A carbon footprint measures the total greenhouse gas emissions caused directly and indirectly by an individual, organization, event, or product. 20. What is bioremediation? Bioremediation uses microorganisms to break down or remove pollutants from contaminated soil, water, or other environments. 21. What is stormwater management? Stormwater management controls runoff from rain and melting snow to reduce flooding, erosion, and water pollution. 22. What is the difference between point and non-point source pollution? Point source pollution comes from a single identifiable source like a pipe or drain, while non-point source pollution comes from diffuse sources like agricultural runoff. 23. What is an environmental permit? An environmental permit is official authorization to discharge pollutants, operate facilities, or conduct activities that may impact the environment. 24. What is environmental compliance? Environmental compliance means adhering to environmental laws, regulations, standards, and other requirements applicable to an organization's operations. 25. What is thermal pollution? Thermal pollution occurs when industrial processes discharge heated water into natural water bodies, disrupting aquatic ecosystems. 26. What is the purpose of an environmental management system? An EMS provides a framework for organizations to manage their environmental responsibilities systematically and improve environmen
