What would make PPE unsuitable for uses?

PPE (personal protective equipment) can be deemed unsuitable for use if it does not meet the required safety standards, is improperly fitted, or is damaged, such as through tears or contamination. Additionally, using PPE that is not appropriate for the specific hazards present—such as wearing gloves that do not protect against chemical exposure—can compromise safety. Furthermore, if PPE is uncomfortable or restricts movement, it may hinder the user's ability to perform tasks effectively and safely.
