OSHA defines PPE as specialized equipment or clothing worn by an employee for protection against materials that may be infected. It dictates that all employees working under these conditions must be supplied with PPE and ensure that they are disposed properly. To remove PEP securely, you must have the capacity to identify what sites are considered "clean" and what are those that are considered "contaminated." In general, the outside front and sleeves of the confinement outfit and outside front of the goggles, cover, respirator and face shield are considered "contaminated," paying little mind to whether there is obvious soil. Areas considered “clean” are those that you are able to touch while removing PPE. The outside of the gloves are usually contaminated. It is therefore recommended not to touch.
