Is training required for wearing personal protective equipment?

Training is required for the use of some types of personal protective equipment (PPE), such as respirators, safety harnesses, and protective suites for biohazards like Ebola virus. Training is not required, but may be helpful for users of other kinds of PPE, such as gloves, where the proper way of removing a glove without spreading contamination can be a useful bit of information. For other kinds of PPE, such as hard hats, safety shoes, and lab coats, no training may be required.
