How Do Multi-Class Dry Chemical Fire Extinguishers Work?

If you ask any firemen what it takes to produce a fire, you will certainly find out that you need to have 3 points:

A Fuel– some sort of flammable solid, liquid or gas
Oxygen– to respond with the gas
Heat– there have to be enough warmth to get the gas over its flash point. There is a paper on your work desk today that is surrounded by oxygen. It does not burn unless you obtain the paper warm enough.
If you want to put out a fire, you need to eliminate one of the three aspects. When you see firemen fighting a forest fire, they generally try to remove gas or warmth. Either they pour water on the fire to lower the temperature, or they try to bulldoze strips of bare earth to remove the gas.

A co2 fire extinguisher works by eliminating oxygen and also changing it with co2. You might do the exact same point with nearly any kind of non-oxidizing gas (nitrogen, for instance), yet co2 is cost-effective and also simple to shop.

An additional means to remove oxygen is to throw a covering over the fire. Treatment the fire with dust or sand does the very same point. You may have heard that you could put out a cooking area fire by throwing baking soda or salt on the fire. Tossing sand would certainly do the exact same thing, however, the majority of people have more salt in their kitchens compared to they have sand.

Dry chemical fire extinguishers are by far the most usual fire extinguishers in the residence. They could manage all 3 kinds of fires you would locate in a kitchen area or workshop: combustible solids like wood or paper, combustible liquids like gasoline or grease, and also electrical fires. The idea behind a dry chemical fire extinguisher is to bury the gas with an inert solid (just like dirt or sand). A dry chemical extinguisher sprays a really fine power of salt bicarbonate (regular sodium bicarbonate), potassium bicarbonate (virtually similar to cooking soft drink), or mono-ammonium phosphate. These solids coat the fuel and surround the fire.
