154. Bicycle helmet
Abicycle helmet is protective headgear designed to reduce the risk and severity of head injuries if a cyclist falls or is involved in a collision. It normally consists of an impact-absorbing liner, an outer shell and a retention strap that keeps the helmet securely on the head.
A bicycle helmet should fit correctly, sit level on the head and be securely fastened. A damaged helmet should be replaced because its protective performance may have been reduced even when the damage is not immediately visible.
