Step-by-step explanation:
Personal protective equipment (PPE) refers to clothing, helmets, goggles, or other gear designed to protect the body from injury or infection. Examples of PPE include safety helmets, gloves, masks, goggles, and earplugs. PPE should be worn whenever there is a risk of exposure to hazards such as chemicals, biological agents, physical hazards (e.g., falling objects), or loud noise.
For instance, in a science lab, students should wear lab coats, safety goggles, and gloves to protect themselves from chemicals, heat, or other potential dangers. Similarly, workers on construction sites wear hard hats to protect their heads from falling objects, and noise-canceling ear protectors should be worn by individuals working in loud environments.
