Final answer:
OSHA mandates employers to provide personal protective equipment to workers, but none of the options given, such as hand sanitizer, vaccinations, etc., are specifically required for cleaning schedules. Employers must assess their specific needs to determine the required equipment.
Step-by-step explanation:
OSHA requires the regular use of personal protective equipment as part of a cleaning schedule. While OSHA has multiple regulations, when it comes to maintaining a clean environment, providing required personal protective equipment at no cost to workers is one of the mandates by OSHA. Common forms of personal protective equipment include masks, gloves, and earplugs.
However, the answer to the question is not listed as an option in the provided choices. Therefore, we are unable to pick one from the provided options (vaccinations, respirators, hand sanitizer, ear protection) that is specifically required by OSHA as a cleaning schedule routine. Instead, employers are responsible for assessing their particular situation to determine the necessary personal protective equipment needed to appropriately protect workers from hazards.
