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.
