A fire collar is a fire-protection device used to prevent the spread of flames and toxic smoke through penetrations in walls and floors caused by plastic pipes. When a fire breaks out, the collar's intumescent material expands and seals off the opening left by a melting pipe. This barrier helps maintain the fire rating of the wall or floor assembly, buying critical time for evacuation and emergency response. Fire collars are required by many building codes in commercial, industrial, and multifamily residential structures. Easy to install and highly reliable, they're a small investment with significant life-saving potential.
