Protective equipment should not be worn just at the moment of interacting with the industrial hazard, but rather personal protective equipment should be worn long before the employee is going to come into contact with the industrial hazard. Having the protective equipment in place continually will ensure maximum safety is achieved.
An example of this concept would be having goggles in place before handling a chemical. Trying to put goggles on while a chemical is splashing will not protect your face. So remember to wear protective equipment before any accidents occur.
