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 face piece is on. Mask or inhalation hose do not interfere. The helmet is secure while engaged in fire attack, permitting more freedom of movement. Another unique feature is that a firefighter can remove helmet without removing the face piece. There is no interruption of air supply if the helmet must be removed. The Milwaukee Chin Strap is a revolutionary method of improving firefighting safety. This weighs 2 oz. and has a length of 14”.
