SHOCK ABSORPTION / IMPACT
Bump hats are designed to keep the wearer safe from static objects (such as low ceilings or hanging impediments).
A 5 kg flat striker is dropped from a height of 250 mm into the bump cap to perform the impact test, with a maximum permissible transmitted force of 15 kN. Hits are made on the front and back of the bump cap, with the head form inclined at 30° and 60°, respectively, to match the nature of any potential impacts.
Bump caps are designed to protect you against sharp or pointy items (such as corners or protruding elements of static objects) A lower-energy penetration test is performed by dropping a 500g striker from a height of 500mm onto a bump cap attached to a fixed head form.
Was the bump hat inspired by French sailors?
French sailors used to wear caps with pom-poms on them so they wouldn't hit their heads on the ship's low ceilings and get harmed. The bobble acted as a protective cushion to prevent head damage when the sea became rough. So, it seems we should thank the French sailors for saving our head from many painful headaches or much worse.
