hazardous substances in the air
✔✔Physical Health Hazards - ✔✔• Includes fires, dangerous reactions, and explosions
, ✔✔Workplace Communication Programs - ✔✔• OSHA requires all employers to provide
information to their employees about the hazardous materials and chemicals to which
they are exposed by means of a hazard communication program
