in that they are able to put out a fire before it gets a chance to spread. Fire sprinklers are the ideal defence against fires. In the YouTube film “How Are Fire Sprinklers know There’s a …” investigates the way the fire sprinklers operate.
First, the temperature at the sprinkler heads increases from 135 degrees to 165 degrees Fahrenheit during the time a fire is developing. In the process, the liquid containing glycerin inside the glass bulb enlarges, shattering the glass. The heat then turns on the fire sprinkler closest to the flames. The head of the sprinkler releases pressurized water , which smothers the flames. The layout of the sprinkler system decides how much water it releases.
Some fire protection sprinklers selectively turn on the sprinklers nearest to the fire Some are made to be able to turn on all the sprinklers within the system. It’s crucial to understand that sprinklers for fire aren’t specifically designed to extinguish fires of a significant size. Instead, they’re intended as a means of securing infernos until the fire brigade is ready.
