Final answer:
The requirement to make the exposure control plan available to OSHA falls under Health and Safety Law, which is enforced by OSHA to ensure a safe work environment.
Step-by-step explanation:
The exposure control plan that must be made available to the Assistant Secretary and the Director of the Occupational Safety and Health Administration (OSHA) pertains to Health and Safety Law. This plan is part of a set of regulations established by OSHA to ensure that workplaces are safe and free of serious hazards. Employers are responsible for adhering to OSHA standards, which include preventing exposure to harmful chemicals, providing necessary personal protective equipment, offering safety training in a comprehensive language, and maintaining records of work-related injuries and illnesses.
Employers must also notify OSHA in the case of serious workplace incidents, such as fatalities or hospitalizations. Under OSHA, workers have the right to a safe workplace, to report injuries or illnesses, to participate in OSHA inspections, and to file a complaint if they face retaliation for exercising these rights.
