The Occupational Safety and Health Administration (OSHA) requires that employers assess the workplace for hazards and select appropriate personal protective equipment (PPE) to ensure worker safety. OSHA's regulations do not specifically require that different categories of PPE meet or be equivalent. Instead, OSHA requires that all PPE be adequate to protect against the specific hazards present in the workplace and be properly fitted and maintained. This means that employers must evaluate the potential hazards in their workplaces and choose PPE that is appropriate for the specific job tasks and conditions. Additionally, employers must ensure that workers are trained on the use and care of their PPE, and that the PPE is periodically inspected and replaced as necessary.
