Final answer:
The Occupational Safety and Health Act of 1970 requires workplace hazard assessments to ensure safe working conditions for employees.
Step-by-step explanation:
The Occupational Safety and Health Act of 1970, also known as PL 91-596, requires workplace hazard assessments. The act grants the authority to the Occupational Safety and Health Administration (OSHA) to issue regulations to ensure safe working conditions for employees. These regulations include limits on hazardous chemical exposure, requirements for the use of personal protective equipment, and measures to prevent falls and hazards from dangerous equipment. OSHA standards also require employers to provide training to workers in a language they understand, keep accurate records of work-related injuries, and notify OSHA in case of workplace fatalities or hospitalizations.
