To provide adequate protection, PPE must properly fit your body. Improperly fitting PPE might not provide any protection at all and could present additional hazards. For instance, safety gloves that are too big can become dangerous if they are loose or get caught in machinery. Respirators that don't fit could expose you to chemical hazards, and ill-fitting safety harnesses could result in falls.
Your employer should provide you with properly fitting PPE. Let your employer, job steward, and/or business agent know if your PPE does not fit.
