The 3M hard hat with 4-Point ratchet suspension H-700 series is comfortable, tough and lightweight safety headgear that helps protect the top of the head due to the potential hazard of small falling objects or exposed fixed objects that may be bumped into. The rigid shell of the hard hat helps reduce chances of injury by deflecting small falling objects from striking the head of the person who wears this safety headgear. The hard hat also helps protect from injuries due to bumping into stationary objects such as pipes, rods, shafts, construction timbers, branches, or exposed electrical conductors. The suspension system inside the hard hat helps absorb the effects of the impact to dissipate the force. Even small objects can cause significant injury due to the force built up from the momentum of falling. Something as small as a washer or coin can strike with the force of several pounds if it falls far enough. 3M hard hats reduce the impact if a strike occurs.
