Firestopping restores the fire resistive ratings of building materials that have been disrupted with penetrations for plumbing, HVAC, electrical, etc. In the event of a fire, this helps prevent the spread of fire and smoke through a building. Every building is different, and every building needs to meet compliance for it's fire rating for the safety of the lives of those you use the building.
