Improving on an old classic, the water mist fire extinguisher uses different technology to spray the water which means it causes less damage, lasts longer and covers a larger area, and can tackle more classes of fire.
It is able to do this because the water is propelled in tiny particles thanks to a specifically-designed rotor generating a fine mist of 40-60 micron molecules. On contact with the flames, the mist turns to steam which envelopes the fire, cooling the blaze down and reducing oxygen levels.
Water mist and foam mist fire extinguishers work in much the same way and are safe to use on Class A (solid combustibles such as wood, paper, textiles, and rubbish) and B (flammable liquid) fires, as well as those involving live electrical equipment.
Before you use a water mist fire extinguisher, first ensure that the extinguisher is safe to use. Check it is fully charged by looking at the gauge, and ensure the safety pin is not damaged. Most importantly, make sure you can still safely exit if your attempts to put out a fire are unsuccessful.
How To Use A Water Mist Fire Extinguisher
- With the water extinguisher on the ground a safe distance from the fire, remove the safety pin and break the tamper seal.
- Aim the hose at the base of the fire with one hand. Don’t aim for the flames, but instead for the base, moving the jet across the area of fire.
- Holding the lever in your other hand, you then start to slowly squeeze it to discharge the water. As the fire starts to die down, you can then move closer.
- Using the entire contents of the water fire extinguisher, make sure the fire is fully extinguished to cool down the area to prevent it from re-igniting.
