Hazardous Materials Storage Safe storage, handling and transfer of hazardous materials is key to reducing chemical accidents and dangerous mixtures of incompatible materials. Close storage of incompatible chemicals could create a risk of fire, explosion, or release of toxic gases and fumes. Storage locations should be according to fire code, have proper fire protection and are structurally appropriate. The Emergency Planning and Community Right to Know Act (EPCRA) and Risk Management Program (RMP) General Duty Clause requires owners and operators of facilities that have any extremely hazardous substances to manage their chemicals safely and develop safety precaution such as instituting maintenance, monitoring, and employee training. When visiting hazardous material facilities, indicators of a well-maintained storage area are: Visible and clearly legible labels Storing like chemicals with like chemicals Safety alarms/interlocks and secondary containments are in proper working order Facilities have policies on hazardous material storage, handling, disposal, maintenance and monitoring in place Warnings and cautions for process chemicals and consequences for process deviations are clearly visible Employees are aware of chemical and reactive hazards, access to safety data sheets and emergency plans Tanks, pipes and valves are clearly labeled with chemical content; valves are locked and only accessible by authorized employees epfl.ch Resources EPA Risks of Improper Storage of Hazardous Chemicals – Common compliance concerns and actions chemical storage facilities must take to operate in a safe manner.
