Helmet "Punished" by Cannon to Test Nondenting Ability

Item

Steel headgear worn by England's fire guards must be able to “take it” under a hail of antiaircraft fragments if they are to give adequate protection. In one test, shrapnel balls are fired at the helmets to make sure they will not be so dented that the metal comes into contact with the head.
