What Class of Fire Require Wet Chemical Fire Extinguisher and Water Mist Fire Extinguisher
What Is Wet Chemical Fire Extinguisher?
The main ingredient in a wet chemical extinguisher is potassium acetate, often with added potassium citrate or potassium acid carbonate. When operated, a wet chemical extinguisher creates a fine mist, which cools the flames and prevents splashing.
How Does
The potassium salts then have a sanctification effect on the oil’s surface, creating a thick, slippery foam layer that smothers the fat and prevents re-ignition. The chemical foam also will cool the fat over a protracted period of your time.Unlike other extinguishers, the thought is to completely empty the contents into the fat fryer to enable the cooling process to start. A noteworthy point is that the contents are often corrosive therefore the quality extinguishers are made up of chrome steel.
Which Class Of Fire Is It Used For?
Wet chemical extinguishers are suitable to be used on Class A & F Fires. This extinguisher is to be used for cooking fires caused by fat and oils. Wet chemical fire extinguishers are ideal for restaurants and kitchens specifically being to be used on fats and oils.
Components Of Water Mist Fire Extinguisher
The most versatile of the set, the water mist extinguisher, use a more modern technology that works across most classes of fireside. The main component of this type of fire extinguisher is deionized water.
How Does Water Mist
This type of extinguisher releases microscopic water molecules that fight the hearth on a spread of levels. First, because such a lot of water is dispersed in such a microscopic fog-like form, the extent of oxygen within the air is decreased, which helps to suffocate the hearth.Second, the water particles are drawn to the hearth and, as water always does, acts to chill it, reducing the temperature.Finally, and maybe what’s most original about the water mist extinguishers, is that the water has been de-ionized (the minerals are removed). As a result, it can actually be used on electrical fires, because the de-ionized water won’t act as a conductor
For Which Type Of Fire Is It Suitable?
Water mist fire extinguishers are the all-rounders of extinguishers because they are proving to be effective, clean, and safe on many types of fires. Most can be used on Class A (combustible) and Class C (electrical) fires.
