Bicycle Helmet Safety 3/25/2010
Do I really need a bicycle helmet?
Yes! The average careful bike rider crashes about every 4,500 miles. Head injuries cause 75% of the more than 700 bicycle crash related deaths every year in the United States. Medical research shows that bike helmets can prevent 85% of bicyclists’ head injuries. A helmet reduces the peak energy of sharp impacts caused by a crash. Even at low speeds, a fall from a bicycle can cause serious head injury.
How do I pick a good bicycle helmet?
Make sure your helmet fits well to get all the protection you are paying for. A good fit means the helmet is level on your head, touching all around. The fit of the helmet should be snug but not tight. The helmet should not move more than an inch in any direction.
The helmet must stay in place through more than one impact. For example, the helmet must stay on if a cyclist is hit by a car, then when the cyclist hits the ground. For the helmet to stay in place, it must have a strong strap and an equally strong fastener. With the strap fastened, you should not be able to remove the helmet regardless of any combination of pulling or twisting. If the helmet is removable with the strap in place, choose another helmet. The helmet should not come off or slip enough to leave areas of your head unprotected.
Choose a white or bright color for visibility. Avoid helmets with a squared off shell, thin straps, or a rigid visor that could snag in a fall. Choose a helmet with a smooth, rounded outer shell, not one with sharp ribs or snag points. “Aero” helmets are not noticeably faster and in a crash, the tail could snag or knock the helmet aside.
How often should I replace my helmet?
If you have been in a crash, replace your helmet. Although the helmet may not have visible signs of damage, the inner foam may be crushed. If the strap of fastener shows signs of wear or become damaged, replace your helmet. Many manufacturers recommend replacing your helmet every 5 years. With constant usage, every 5 years is a good rule of thumb. If you do not ride your bike often, you may go longer on one helmet. Whatever the age of your helmet, inspect the helmet often for any signs of wear or damage. If there is damage, don’t take chances with your protection. Replace your helmet.
Warning!
Do not allow children to play on playground equipment, climb trees, etc. with their bicycle helmet on. The helmet or strap could snag and choke a child.
Bicycle helmets are only for use while you are on a bicycle. If you are on a motorized vehicle, choose a different helmet.
