PPE stands for personal protective equipment.  PPE means any device or appliance designed to be worn or held by an individual for protection against one or more health and safety hazards.

Hard hats are normally supplied with an information tag attached giving advice & lifetime expectancy. Some manufacturers say 3 years, others say an in use life of up to 5 years. Obviously how much exposure that they have had, how they have been stored, how many knocks they have had will determine the replacement interval.

Generally the following advice will apply:
Safety helmets need to be changed when damaged, when they have been involved in an accident, when affected by sunlight and so forth. Hard hats will need replacing when the harness is damaged or if it is likely that the shock absorption or penetration resistance has deteriorated. For example, when the shell has received a severe impact, or if deep scratches occur (i.e. to a depth greater than 25% of the shell thickness) or if the shell has any visible cracks. Good maintenance will also keep the hat in good working order and prolong its life. Assuming they have been well maintained & none of the above apply , replace  according to manufacturer's instructions.

Safety helmets should:
(a) be stored in a safe place, e.g. on a peg or in a cupboard on site;
(b) not be stored in direct sunlight or in excessively hot, humid conditions because long-term exposure can weaken the shell;
(c) be checked regularly for signs of damage or deterioration;
(d) have defective parts replaced (if the model allows this). Parts from one model cannot normally be interchanged with those from another;
(e) have the sweatband cleaned regularly or replaced.

Certain chemicals can weaken the plastic of the shell leading to rapid deterioration in shock absorption or penetration resistance. Chemicals that should be avoided include aggressive cleaning agents or solvent based adhesives and paints. Where names or other markings need to be applied using adhesives, advice should be sought from the helmet manufacturer.
