Personal Protective Equipment (PPE) refers to workplace accessories that are designed to create a barrier against workplace hazards. PPE includes items such as helmets, gloves, goggles, and masks, which are worn by workers to protect themselves from potential injuries or illnesses. Unlike engineering controls, which involve modifying the workplace environment to minimize hazards, PPE directly protects the individual worker. Administrative controls, on the other hand, involve implementing policies and procedures to reduce exposure to hazards. Headphones, while they may provide personal comfort or entertainment, do not serve as protective equipment against workplace hazards.
