The seven safety measures for controlling hazardous chemicals are conducting a risk assessment to identify potential hazards and determine control measures, using engineering controls such as fume hoods or exhaust systems to minimize exposure, implementing administrative controls such as limiting access to hazardous areas and enforcing safety protocols, providing proper personal protective equipment tailored to the type of chemical hazard, ensuring safe storage of chemicals in labeled, compatible containers and appropriate conditions such as temperature or humidity, educating and training individuals on chemical hazards, safe handling procedures, and emergency response, and regularly inspecting and maintaining safety equipment, storage areas, and handling tools to ensure ongoing compliance and safety.
