Blood is not an effective extinguishing agent for fires. Water, foam, or chemical fire extinguishers are typically used to put out fires.
Water, foam, powdered chemicals like sodium bicarbonate
yes, because many modern fires contain chemicals and other elements that burn hotter, and are often not affected by water. foam works better because it is specifically designed to put out fires that are either not affected by water, or become more intense when water is added, much like grease fires that arise when cooking.
No, foam is not recommended for oil fires as it can actually spread the fire and cause it to flare up. Foam is better suited for extinguishing class A and B fires, such as wood or paper fires. For oil fires, it is best to use a fire extinguisher specifically designed for class K (kitchen) fires or a fire suppression system designed for commercial kitchens.
Foam is effective at extinguishing class B fires, which involve flammable liquids such as gasoline, oil, and solvents. It works by forming a blanket over the burning liquid, smothering the flames and preventing oxygen from reaching the fuel. Additionally, foam can also be used on class A fires involving ordinary combustibles like wood and paper, but its primary application is in liquid fire scenarios.
put foam over the foam
Using foam extinguishers on certain fires can be dangerous because they are not suitable for fires involving flammable liquids (Class B fires) or electrical equipment (Class C fires). Foam can spread flammable liquids, worsening the situation, and may conduct electricity, posing a risk of shock or electrocution. It’s crucial to use the correct type of extinguisher for each class of fire to ensure effective suppression and safety.
