Head injuries may be caused by falling or flying objects, or by bumping the head against a fixed object. Protective helmets must do three things:
- Resist penetration.
- Absorb the shock of a blow.
- Protect against electrical shock.
Head injuries may be prevented by the selection and use of appropriate head protection.
Classes of headwear can include:
- Type 1 - protection from impact and penetration at the crown (top) and
- Type 2 - protection from impact, penetration at the crown (top) and laterally (sides and back)
- Each type is also available in the following classes:
- Class E (20 000 V electrical rating) - non-conducting material (electrical trades)
- Class G (2200 V electrical rating) - non-conducting material (general trades)
- Class C (no electrical rating)
Our Product Range
- Headwear consists of a shell and the suspension. These work together as a system and both need regular inspection and maintenance.
- Do not transport headwear in rear windows of vehicles. Heat and UV light can damage the material, making it brittle and less protective.
- Inspect headwear before each use.
- Always check with the manufacturer when adding or using accessories (non-metallic stickers, tape, bandanas, hankerchiefs, welder's cap, etc.).
- Winter liners should be inspected to ensure they do not interfere with fit of headwear.
- Do not draw the chin strap over the brim or peak of the headwear.
- Do not wear baseball style hats under the headwear as it interferes with the suspension.
- Only wear the hard hat with the peak at the back, if the suspension has been adjusted so the nape strap remains at the back of the head. Check with the manufacturer to ensure the headwear was designed to be worn this way.
- If high visibility headwear is required, consult with CSA Standard Z96 for colour and retroreflective performance specifications.
- Insect repellant or other chemicals can degrade the headwear material. Ask the manufacturer if the products are compatible.
The shell is rigid and light, and is shaped to deflect falling objects. Correct maintenance is important.
- Inspect and replace a shell that shows signs of wear, scratches or gouges. Shells exposed to heat, sunlight and chemicals can become stiff or brittle. A visible pattern of tiny cracks may develop. Over time, weathered hats can become dull in colour or have a chalky appearance.
- Replace headwear when any of the above signs of wear start to appear.
- Replace headwear that has been struck, even if no damage is visible.
- Remove and destroy any headwear if its protective abilities are in doubt.
- Do not drill holes, alter or modify the shell. Alterations may reduce the protection provided by the headwear.
- Do not paint the plastic shell. Paint solvents can make plastic headwear brittle and more susceptible to cracks. Paint can also hide cracks that may develop. Instead, use reflective marking tape to make numbers or symbols for identification purposes. Some headwear may be painted, but check with the manufacturer for approval.
- Do not use winter liners that contain metal or electrically conductive material under Class G or E headwear.
- Do not use metal labels on Class G or E headwear.
The suspension system is as important as the shell. It holds the shell away from the head and acts as a shock-absorber. It also holds the shell in place on the head and allows air to flow freely.
- Adjust headband size so that headwear will stay on when the wearer is bending over, but not so tight that it leaves a mark on the forehead.
- Ensure that the suspension is in good condition. The main purpose of the suspension is to absorb energy.
- Look closely for cracked or torn adjustment slots, frayed material or other signs of wear.
- Check the suspension lugs carefully. Long periods of normal use can damage the suspension. Perspiration, hair oils, dirt, insecticides, hair sprays and hair treatments can speed up the deterioration of suspension materials.
- Replace the suspension if it has torn or broken threads.
- Only use liners if approved by manfuacturer.
- Do not put anything between the suspension and the shell. There must be a clearance inside the headwear while it is being worn. In case of a blow to the head, that space helps absorb the shock.
- Do not use a suspension made by one manufacturer with products made by another manufacturer.
- Do not change or alter any of the suspension, liner or shell.
The care and maintenance of headwear are needed if the headwear is to protect as designed. Its lifespan is affected by normal use and by heat, cold, chemicals and ultraviolet rays.
