During Hawthorne Day on September 23, 2017, the Hawthorne Fire Department will be demonstrating a live side-by-side burn of two “rooms”—both are furnished as a typical living room, bedroom or dorm room. The difference is that one of the rooms has a smoke alarm, while the other has a smoke alarm and a single sprinkler head. The demonstration will reveal the speed at which the fire sprinkler suppresses the fire in one room—usually under a minute—while the other room continues to burn and is already at flashover (the point at which everything in the room ignites) before a fire department typically arrives on scene.


Video shows two rooms set on fire; one with a sprinkler system, the other without. While the sprinklers extinguished the flames in one room within 80 seconds, the room without sprinklers was reduced to ash in a few quick minutes. Fire sprinklers truly save lives and protect property.
