PPE stands for "personal protective equipment." PPE Category 3 refers to equipment that is complex and provide the highest level of protection such as powered respirators, SCBA, and full body suits. In Europe, PPE Category 3 must meet certain safety standards set by the European Union, which means that it must be designed and manufactured to protect the user without causing harm. Companies that make or sell PPE must prove that it meets these standards. They also must have a quality management system in place, have to be audited regularly by a notified body and have to have a technical documentation.
