Final answer:
Employers have the primary responsibility to provide and ensure the use of PPE according to OSHA, but individuals are ultimately responsible for properly using the PPE that is provided to them.
Step-by-step explanation:
Under the Occupational Safety and Health Administration (OSHA), employers have the primary responsibility to provide a safe workplace, which includes providing the necessary personal protective equipment (PPE) at no cost to workers and ensuring that it is used properly. While OSHA sets and enforces standards, and the company's management has the responsibility to comply with these standards and provide appropriate PPE, it is ultimately the responsibility of the individual employee to use the PPE properly once it is provided. Thus, employers, supervisors, and the individuals altogether bear responsibility for the proper use of PPE to ensure safety in the workplace.
