Manufacturing Skill Standards Council (MSSC) Safety Assessment Practice Test

Who sets the PEL (Permissible Exposure Limit) for exposure to hazardous substances?

1. OSHA

2. EPA

3. NAFTA

4. FDA

The correct answer is: OSHA

The Permissible Exposure Limit (PEL) is established by the Occupational Safety and Health Administration (OSHA) as part of its regulatory authority over workplace safety. OSHA's role includes ensuring that occupational environments are safe and healthy for workers, and setting PELs is a critical aspect of this responsibility. These limits are designed to protect workers from the health risks associated with exposure to hazardous substances, such as chemicals, dust, and gases. While the Environmental Protection Agency (EPA) also plays a role in regulating hazardous substances, its focus is primarily on environmental protection rather than on exposure limits specifically in the workplace. The North American Free Trade Agreement (NAFTA) is not related to occupational safety or exposure standards, and the Food and Drug Administration (FDA) is primarily concerned with the regulation of food, pharmaceuticals, and medical devices, not workplace safety. Thus, OSHA is the appropriate agency that sets the PEL to ensure safe working conditions regarding hazardous substances.
