Head injuries are serious and may result in headaches, concussion, brain damage and even death. Hard hats and helmets for specialized activities are designed to minimize head injuries
Use a hard hat that is correctly rated for the job and meets the appropriate CSA, ANSI or standards of the authority having jurisdiction (AHJ). There are several types and classes of hard hats. The webbing inside hard hats should provide shock absorption from falling objects, lateral impacts and help protect your head during a fall.
Use a face shield attached to the hard hat for protection from chemicals, dust or electrical sparks etc., as required.
Inspect your hard hat every day before use. Replace it if the shell is damaged, i.e., cracked, brittle, dented, discoloured or flaking, or if the strap system is frayed or torn. Hard hats should be replaced at least every three to five years as they can become brittle. The strap system should be replaced annually if it is used frequently.
Make sure the hard hat fits properly; it should stay on when you bend over but not be so tight that it marks your forehead. There should be 2.5 cm (1 in) between the shell of the hard hat and the strap system that absorbs the shock.
Never wear your hard hat backwards; in that position it cannot protect your head as it is designed to do. Do not insert anything between the webbing and the shell or the suspension will not be able to absorb an impact properly
Seasonal issues: In winter, wear a hard hat liner for warmth during very cold temperatures but make sure the hard hat fits over it correctly. In summer, hard hats may
Use a chin strap to secure the hard hat when it is windy or when working at or near a helicopter landing area
Care for the hard hat correctly. Clean and store it correctly. Do not paint it or apply solvents as these can make the shell either soft or brittle have fabric attached to protect the worker's neck from sun, but the hat must fit correctly
Regional legislation may require riders and passengers to wear government approved helmets when riding ATVs, snowmobiles or a 2-wheel motor bike. Helmets worn with a face shield provide the most protection. Refer to Chapters 14. All-Terrain Vehicles and 15. Snowmobiles for additional information
When traversing in mountainous terrain where falling rocks may be a risk, it may be advisable to wear a climbing or mountaineering helmet with a secure chin strap rather than a hard hat. Mountaineering helmets are designed with no brim to prevent them from catching on rocks should you slip and fall
Where legislation does not require the use of helmets, employees should use common sense and wear a helmet when conditions are hazardous
