Fire Collar – Before, During & After Fire

Many would install and specify fire collars and would know what they are designed to do. But maybe you haven’t seen an activated fire collar. This photograph here show a fire collar before exposed to fire, during, and after fire. The intumescent material expands when exposed to heat crushing the plastic pipe as it softens and plugging the hole, which therefore prevents the fire spreading to the adjourning compartment.
