How do fire sprinklers work?

Fire sprinklers, also known as fire sprinkler systems, are vital safety devices designed to detect and control fires in commercial, industrial and residential buildings. They operate automatically, helping to contain and extinguish the fire before it spreads. Here is an explanation of how fire sprinklers work:

1. Heat detection: Fire sprinklers are activated by a heat detection mechanism. Each sprinkler has a fragile glass bulb or a thermosensitive element that contains a heat-sensitive liquid. The melting point of this liquid is designed to correspond to a certain temperature. When this temperature is reached due to the heat of the fire, the liquid expands and breaks the bulb or releases the activation mechanism.

2. Individual activation: Each sprinkler is independent and is activated individually, which means that not all sprinklers fire at the same time. Only the sprinklers in the area where the heat has reached the activation temperature will be triggered.

3. Water discharge: When the activation mechanism is triggered, the sprinkler releases pressurized water directly onto the area affected by the heat. The water pressure is maintained at a level that allows only the activated sprinkler to work, avoiding unnecessary activation of other sprinklers.

4. Fire suppression: The water released by the sprinkler cools the fire, reduces the ambient temperature and prevents the fire from spreading. This helps to control the fire and prevent significant damage or the spread of the fire to other areas of the building.

5. Alarm: Many sprinkler systems are also connected to an alarm system, which is activated when one or more sprinklers go off. This alerts building occupants and emergency responders to the fire in progress.

It is important to note that fire sprinklers are highly effective in containing and controlling fires. They can significantly reduce fire damage and, most importantly, save lives by providing more time for safe evacuation. However, each sprinkler system must be designed and installed in accordance with the fire safety regulations specific to the region and type of building.
