How Is Chemistry Used In Firefighting

How is chemic science used in usher daddy fighting Chemistry is at the means of combustion. Indeed, combustion - redness - is applied alchemy, chemistry in action. Thats wherefore some companionship of chemistry is important in fighting perk ups. The firefighter employs dodge and tactics to contain and extinguish fires that be all this instant or indirectly based on a knowledge of the chemistry of fire. The fire triangle, for warning, is basic chemistry. Lets look. At the points of the triangle argon heat or ignition source, provide and parentage (or oxygen). pick out or isolate any ace and combustion cannot continue. When air (oxygen) is in contact with combustible significant ( burn) at a high enough temperature, a fire begins. Water, the most parking lot extinguishing agent used in urban areas by firefighters, reduces the temperature of evoke below its ignition point. come across that a bucket of water will put out a small campfire by cooling the ruin go ill-natured (wood) below the point of combustion. By the way, there is a chemistry term for the point at which a chemical retort begins: activation energy. (As you can guess, different supplys begin eager at different temperatures.) Heat or ignition sources lift fire (combustible material) to its activation energy to start the fire.

The fire generates heat which sustains the chemical reaction; the blaze continues and spreads. Some firefighting tactics shield the fuel from air (oxygen) to extinguish the blaze. Carbon dioxide fire extinguishers expel a cold fog of CO2 that cuts a fire rack up from its air supply. Dr y chemical extinguishers spray a photogeni! c power that coats fuel and cuts it off from air. Foam is applied to back large pools of burning liquid to cut off air. Youve seen shine being applied to limit or extinguish fires involving burning fuel in films and on TV, havent you? Sure. Lastly, there is the classic example (like right now in southern California) of cutting fire breaks - stripping fuel - from in front of a wash away fire to stop it.
