1. What does OSHA stand for? Occupational Safety and Health Administration 2. was created by the US department of labor to regulate and enforce safety and health standards to protect employees in the work place... 3. This regulates employee exposure to potentially toxic substances and inform employees about the possible hazards of materials used in the work place? 4. This requires that chemical manufacturers and im- porters assess and communicate the potential haz- ards associated with their ...
