Personal Protective Equipment (PPE) is clothing or equipment designed to protect the wearer against workplace hazards. PPCE should only be considered when the hazard cannot be eliminated or where the risk cannot be controlled using other methods from the hierarchy of controls (Substitution, Isolation, Engineering, Administration and PPE).
PPE is the least effective control measure because the hazards and risks are still present. There are also issues of proper fit and design for different individuals. PPE can sometimes be awkward, uncomfortable and limiting, which may make workers less likely to use such equipment.
