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.
