Flashover is the point when everything combusts-and there is no chance of survival when it occurs. The video “Fire Power!” tells the dramatic story of how quickly fire spreads and destroys a residential home. While it was a staged fire, with working smoke alarms, it presents a clear case of why residential fire sprinkler systems can provide critical defense against a devastating fire.
In a related demonstration with side-by-side structures-one is protected with fire sprinklers, the other is not-the fire sprinkler extinguishes the fire in just 30 seconds, whereas a raging flashover in the room without a fire sprinkler system provides striking evidence that fire sprinklers can help save lives.
