A 40-year-old journeyman lineman working in Alaska got too close to a 17,400-volt charged circuit while replacing cables under a switchcabinet - he didn't live to tell the story. His head either touched the switch or got close enough to allow electricity to arc between the energized post and his head.

The outcome might have been much different if he'd been wearing a dielectric (non-conducting) Class E hardhat. But his "head protection" consisted of a cloth cap, which offered no protection at all.

IIn their report on the fatality, investigators noted that foreman-level and journeyman-level electricians and linemen are among the most experienced and knowledgeable workers in the electrical contracting industry, receiving extensive training in electrical safety. However, failure to use required protective equipment accounts for 55 percent of utility linemen fatalities.


So what does this have to do with you? Perhaps more than you realize. Even if you're not a lineman or electrician, your job could expose you to electrical hazards. And if you aren't wearing a non-conducting hardhat and other suitable personal protective equipment, you could be gone in a flash.

All three classes of hardhats protect the head against injury from moving or fixed objects, but only Class E and Class G hardhats also protect against electrical hazards. If your task involves the potential risk for electrocution through head contact with electrical conductors, check the label inside your hardhat.


Ray Mullin, vice-chair of the Canadian Standards Association (CSA) Z94.1-05 Industrial Protective Headwear Standard, says it is important to be aware of the dangers of modifying hardhats or wearing winter liners. It could wipe out any of the protection it is designed to provide. In particular, do not:

Choose the right hardhat for your job. But remember, staying safe is not simply a matter of using your hardhat. You must use your head, too.
