MAINTENANCE OF A HARDHAT SHOULD NOT BE IGNORED

The hardhat is one of the most important pieces of protective equipment worn by employees in the industry. Many people have been saved from serious injury because they were wearing this durable headgear.

The Industrial Safety Equipment Association (ISEA) points out, however, that the care and maintenance of the hardhat cannot be ignored if it is to supply the protection from which it is designed. Its useful life is affected not only by normal use but also by various environmental factors such as heat, cold, chemicals and ultraviolet rays.

The protective hat or cap consists of two basic components - the shell and the suspension - -which work together as a system. Both need regular inspection and maintenance.

The shell is rigid, light and is shaped to reflect a falling object. Wearers should inspect the shell regularly according to the ISEA. When cracks, even as small as hairlines, become apparent, the helmet should be replaced because experience has shown, these cracks will spread and widen once they begin to form. Look for signs of abuse such as scratches or gouges. Shells exposed to heat, sunlight and chemicals can become stiff or brittle. There can be visible craze pattern. It can be dull in color or have a chalky appearance. Replace these helmets also.

The ISEA also recommends that if the hat has sustained an impact from an object, it should be replaced, even though no damage may be visible. Further, whenever the fitness of a hat is in doubt, it should be taken from service immediately and destroyed.

The suspension system inside the helmet is as important as the shell itself. The obvious benefits are that it holds the shell in place on you head, so you can move around and work without losing it. Also, it holds the shell away from your head and allows air to flow freely.

The main purpose of the suspension is to absorb energy. For that reason, it is important that the suspension be in good condition to perform that function.

Over long periods use, the suspension can become damaged and worn. Wearers should look closely for cracking, torn adjustment slots, fraying material, or other signs of wear, especially at the suspension lugs. These can be caused be hair oils, perspiration, and normal wear. The ISEA recommends that suspensions be routinely replaced at least once a year under normal wear conditions.

The service life of the protective headgear can be lengthened by cleaning the suspension and shell as part of a regular inspection program. A wet sponge or soft brush with mold detergent and water will remove dirt and stains from the suspension and shell.

In addition to recommending inspection and maintenance of hardhats, ISEA has issues several notes of caution concerning their use and treatment. Employees should not carry anything inside the helmet. A clearance must be maintained inside the helmet for the system to work. In the event of a blow to the need, the space must be used to help absorb the shock of the blow.

Never alter or modify the shell other than in accordance with the manufacturers’ instructions to permit the use of accessories. Such accessory attachments may reduce the limited protection provided by the helmets. If it is necessary or desirable to use the numbers or symbols in the helmets for identification purposes, the ISEA recommends the use of reflective marking tape. Only the helmet manufacturer should paint the helmet to avoid the problem of the solvents in the paint that can make the helmets brittle and more susceptible to cracks.

The ISEA points out the hardhats have done a good job protecting workers in a variety of work environments. They will provide a reasonable service life if given a little care and regular inspection.
