Final answer:
Employers must supply and maintain suitable personal protective equipment (PPE) for their employees as per OSHA standards, and ensure it is properly sanitized.
Step-by-step explanation:
The correct statement about personal protective equipment (PPE) is that employers must supply PPE, and they are responsible for ensuring its adequacy and maintaining and sanitizing it as necessary. While employees can indeed provide their own PPE, employers ultimately have the responsibility to ensure that it is suitable, maintained, and sanitized according to Occupational Safety and Health Administration (OSHA) standards. Employers are tasked with providing a safe work environment, and part of this involves supplying and maintaining appropriate PPE for their employees.
