How does it work? The extinguisher’s supersonic nozzle disperses microscopic ‘dry’ water mist particles to suppress fires and extinguish burning materials. The particles are attracted by the fire and cool the fire and reduce oxygen content.

When using a water extinguisher Where should you direct the stream of water?

Aim the nozzle or outlet towards the base of the fire. Squeeze the handles together to discharge the extinguishing agent inside. To stop discharge, release the handles. Sweep the nozzle from side to side as you approach the fire, directing the extinguishing agent at the base of the flames.

How does a water misting system work?

How a Misting System Works. All misters work with evaporative cooling – the natural cooling effect that happens when water evaporates in warm air. … Water is forced through very small nozzles to create a fine mist or a very, very fine fog. As the droplets of water evaporate they cool the air immediately around them.

Is a water mist system a sprinkler system?
