Passive fire products are the first line of defence in a fire, and they work by reacting to fire without human intervention - sealing openings to contain fire in a building by means of compartmentation, by retarding the passage of flames across a surface, and by resisting the penetration of fire into structural elements such as doors. This not only limits the damage to property, but gives time for people to be evacuated safely from the building, and allows firefighters to get to the scene.
