Do not store objects between the suspension and the shell of the hard hat because they may affect the protection capabilities of the unit. Prolonged exposure to sunlight will degrade most plastic shells. Do not store them in direct sunlight when not in use.
What are the signs of the hard hat when damaged?
Any hard hat that fails the visual inspection should be removed from service and replaced. Hard hats should be free from signs of impact (i.e. dents, cracks, or penetration) and rough treatment (i.e. abrasions, gouges, or excessive wear).
Do stickers weaken hard hats?
In most cases, the effect of stickers on hard hats does not negatively affect the safety performance provided by the hard hat. There is very little potential for chemical interaction between the type of adhesive used in typical pressure-sensitive stickers and the helmet shell.
What actions can compromise the integrity of hard hats?
Chemicals found in some paints, paint thinners, cleaning agents, and even insect repellant can interfere with the integrity of the shell and may eliminate electrical resistance, and therefore these should never be applied to a cap.
What is the lifespan of a hard hat?
5 years
MSA hard hat shells should be used no longer than 5 years, while suspensions should be replaced after 12 months. Both are the maximum time frame for replacement, calculated from date of first use. The date of manufacture is stamped or molded onto the hard hat shell, usually on the underside of the brim.
How much force can a hard hat take?
According to workingperson.me, all hard hats must achieve ANSI impact standards for worksite use. To achieve this standard, a hard hat must be able to “withstand an 8 pound ball dropped from a height of 5 feet onto the top of the hard hat. Maximum peak force here would be 1000 pounds.”
What is the OSHA standard for hard hats?

How do you inspect a hard hat?
A simple hardhat field inspection involves compressing the shell from both sides about 1 inch with your hands and releasing the pressure without dropping the shell. The shell should return to its original shape quickly, exhibiting elasticity.
Why should you never paint your hard hat?
Can I paint my hard hat? A. Never paint a hard hat. Paint may chemically attack and damage the hard hat’s shell, thereby reducing the degree of protection originally provided.
How often should a hard hat be replaced?

What may happen to your hard hat if you leave it in the sunlight for a period of time?
For hard hats exposed to heat, sunlight, or chemicals, the shell may become chalky, dull, or have a crazing pattern or be less flexible (compare a new and used hard hat by flexing the brim). If any of these characteristics is exhibited, replace the hard hat shell and/or suspension immediately.
Why do hardhats expire?
