If possible, you should try to extinguish the flames using a carbon dioxide or dry powder fire extinguisher.
Where are CO2 fire extinguishers used?
Carbon dioxide fire extinguishers are a very common form of fire extinguisher and are used in situations where traditional water and foam fire extinguishers or dry chemical fire extinguishers are not suitable. A carbon dioxide fire extinguisher is a “clean extinguisher” and leaves no residue on the area it is applied.
When any fire has been extinguished with carbon dioxide there is always a danger of the?
Asphyxiation – If a carbon dioxide extinguisher is used in an enclosed or poorly ventilated area, there is a serious risk of asphyxiation. Higher pressure – When discharged, the carbon dioxide in the extinguisher turns from liquid into gas.
Why does vinegar and baking soda put out fire?
Vinegar mixed with dissolved baking soda causes a quick chemical reaction that creates the product carbon dioxide (CO2). If the chemical reaction occurs inside a beaker containing a lit candle, the carbon dioxide created will accumulate and push out the oxygen, thus extinguishing the flame.
When should you use a CO2 fire extinguisher?
CO2 fire extinguishers are mainly aimed at electrical fires but are also suitable for Class B liquid fires and are used in different ways depending on the type of fire they are being used on. Do not use CO2 extinguishers in small rooms as CO2 gas is poisonous at only 4% concentration and can kill at just 8%.
What should you not use CO2 fire extinguisher?
Dangers: CO2 extinguishers should not be used on fires involving solid materials, such as paper, wood and fabric, and also are not suitable for use on flammable gases. How it works: The CO2 works by cutting off the fire’s oxygen supply. This then smothers it and, as it does so, extinguishes the flames.
What type of fire can we safely use CO2 on?
Carbon dioxide can be used on Class B & C fires. They are usually ineffective on Class A fires. Dry Chemical fire extinguishers extinguish the fire primarily by interrupting the chemical reaction of the fire triangle.
Why you should not use water to extinguish fire all the time?
Water is a good conductor and can increase the possibility of electrocution. Do not use water to extinguish flammable liquid or cooking oil fires. Water is ineffective as it helps to spread the liquid and the fire.
What is powder extinguisher?
Dry powder extinguishers smother fires by forming a barrier between the fuel and source of oxygen. The label colour for this type of extinguisher is yellow. Wet chemical extinguishers can also be used for fires caused by various organic materials including wood, coal, textiles, fabrics, cardboard and paper.
What kind of powder is in a fire extinguisher?
Many fire extinguishers release a fine powder. The most common is the multipurpose dry chemical type, which is used for Class A, B, and C fires. These contain monoammonium phosphate, which comes out as a yellow powder.
Can salt put out fire?
If there’s no lid nearby, douse the fire with plenty of salt or baking soda. Salt will smother the fire almost as well as covering it with a lid, while baking soda chemically extinguishes it. … Avoid using flour or baking powder, which can explode in the flames instead of snuffing them out.
What are the four main ways to control or suppress a fire?
P.A.S.S. is an acronym (Pull, Aim, Squeeze, Shoot) to help remember how to use the extinguisher.
Can elephant toothpaste stop fires?
Second, this material needs to be hot enough so that it can catch fire. The combustion reaction then has to create enough heat to sustain the fire. And lastly, a fire needs oxygen to burn. If either heat, fuel or oxygen are absent, there will be no fire.
