The Milwaukee Chin Strap was developed precisely for people who engage in firefighting. The ability of this chin strap to be separated and joined again when wearing breathing apparatus is its most outstanding feature. The design of the chin strap allows a firefighter to quickly and easily secure the fire helmet after a facepiece is on. Mask or inhalation hoses do not interfere. Helmet is secure while engaged in fire attack, permitting more freedom of movement. Another unique feature is that a firefighter can remove their helmet without removing the facepiece. There is no interruption of air supply if helmet must be removed. The Milwaukee Chin Strap is a revolutionary method of improving firefighting safety. Manufactured in the U.S.A. these straps have been used successfully since 1981.
