Do I need a firestop system if I already have a sprinkler system?
While sprinkler systems are extremely important, they suppress rather than contain the fire. In other words, sprinklers put out flames, but dont prevent them from spreading to that compartment in the first place. Furthermore, sprinklers are useless against smoke and deadly gases. And when you consider that nearly 75% of fire-related deaths are caused by smoke inhalation, the need for a firestop system is even more vital.
