PPE is equipment worn by a person to minimize exposure to specific hazards. An is an example of PPE worn occasionally by people in their homes.
Oven mitts have an occupational use as well.
In the workplace known as the Purdue University Department of Chemistry we concern ourselves with PPE used in many circumstances not ordinarily found in the home of course. Chemical resistant gloves, aprons, lab coats, dust masks, goggles, face shields, for example. Using PPE is only one element in a complete safety program. A variety of strategies and safeguards are necessary to maintain a safe and healthy work environment. These include required other safety equipment and engineering controls, standard operating procedures, and worker training.
