Personal Protective Equipment (PPE) protects the user against health or safety risks. PPE includes safety helmets, gloves, eye protection, high-visibility clothing, safety footwear and safety harnesses. It also includes Respiratory Protective Equipment (RPE). Hazards addressed by protective equipment include physical, electrical, heat, chemicals, biohazards, and airborne particulate matter. Personal protective equipment reduces employee exposure to hazards but only when engineering and administrative controls are not feasible or effective to reduce these risks to acceptable levels. PPE has the limitation that it does not eliminate the hazard at source. Therefore employees may be exposed to the hazard if the equipment fails. Any item from our PPE suppliers imposes a barrier between the wearer/user and the working environment.
