Automatic fire extinguisher
Automatic fire protection systems are used today as the most common form of fire protection. The sprinkler philosophy is based on the action of the appropriate amount of water (the less the better) at the right place (in the center of the fire) at the right time (the sooner the better). Many common systems are supplied with water from the city network, but increasingly water tanks are installed, with pumps to ensure adequate water flow and pressure.
