Fire prevention systems can save lives and limit building damage during a fire, and they are also required by code. Passive fire protection systems are designed to slow the spread of flames, smoke, and poisonous gases in a fire by filling holes in walls, ceilings, and floors created by pipe, cable, and joint penetrations in fire-rated areas. As a result, it is critical to incorporate passive fire protection. It is best to use firestop products into any building design from the start.
