To put out an alcohol fire, it is important to use the appropriate type of fire extinguisher. Alcohol fires can be particularly challenging to extinguish because they burn at a high temperature and can re-ignite easily. Therefore, it is crucial to use the correct extinguishing agent to effectively combat these fires.
One recommended type of fire extinguisher to use is a CO2 (carbon dioxide) extinguisher. CO2 extinguishers work by displacing oxygen, thereby smothering the fire. They are suitable for use on alcohol fires as they do not leave any residue behind, which could potentially reignite the flames. When using a CO2 extinguisher, it is important to aim the nozzle at the base of the fire and sweep from side to side until the flames are fully extinguished.
Another option is to use a halon extinguisher. Halon extinguishers contain halon gas, which is effective in suppressing fires involving flammable liquids, including alcohol. However, halon extinguishers have been phased out in many countries due to their harmful effects on the environment. Therefore, it may be more difficult to find a halon extinguisher readily available.
Alternatively, a dry chemical extinguisher marked as B, C, BC, or ABC can also be used to put out alcohol fires. These extinguishers contain a dry chemical powder that acts as a fire suppressant. The powder works by interrupting the chemical reaction of the fire and smothering the flames. It is important to note that using a dry chemical extinguisher can leave behind a residue, which may need to be cleaned up afterward.
In the case of fuel ethanol fires, an alcohol-type or alcohol-resistant foam (ARF) can be effective in extinguishing the flames. ARF contains a special additive that helps to create a foam blanket over the fire, preventing oxygen from reaching the flames and extinguishing the fire. This type of foam is specifically designed to combat alcohol fires and can be an effective alternative to traditional fire extinguishers.
It is crucial to remember that safety should always be the top priority when dealing with fires. If the fire is too large or spreading rapidly, it is essential to evacuate the area and call emergency services immediately. Additionally, it is important to follow the manufacturer’s instructions and guidelines when using fire extinguishers to ensure their proper and effective use.
In summary, to put out an alcohol fire, the use of a CO2, halon (if available), or dry chemical fire extinguisher marked B, C, BC, or ABC is recommended. Additionally, an alcohol-type or alcohol-resistant foam can be used for fuel ethanol fires. It is important to aim the extinguisher at the base of the fire, sweep from side to side, and follow the manufacturer’s instructions. However, safety should always be the priority, and in case of a large or spreading fire, evacuation and calling emergency services is crucial.
