Firefighting foam is normally used in diluted form - 1-6% foam and 94-99% water, depending on the application. This reduces its corrosive effects, but the pure agent can be quite damaging to equipment over time.
Eg: On the Antarctic FD (Mcmurdo Station, Antarctica) we bought 4 new air rescue firefighting vehicles in 2005 which we filled with a non-freezing undiluted foam/antifreeze mix. When we attempted to use the vehicles for the first time in 2007, the brass fittings on the foam lines blew apart in several places as soon as they were charged, rendering the truck useless. This was due to corrosion by the foam agent, which had leaked past the check valves and filled the foam lines for an extended time.

What are the three ways to extinguishing fire the solid fuel?
The three primary ways to extinguish a fire involving solid fuel are: 1) Cooling the fire by applying water or other extinguishing agents to lower the temperature below the ignition point; 2) Smothering the fire by removing oxygen, such as using foam, blankets, or fire extinguishers; and 3) Starving the fire by removing the solid fuel source, ensuring that there is no material left to sustain combustion. Each method disrupts the fire triangle of heat, fuel, and oxygen.
What are the Extinguishing media used on wheel well fire on aircraft?
A wheel well fire is unique because it can be four of the five fire classes:the tires are Class A--flammable solidsthe fluids are Class B--flammable liquidsyou've probably got electrical actuators in there, so you've also got a Class C--electrical--fire on your hands.and the plane has some aluminum, magnesium and maybe titanium components; heat them up enough and you're looking at a Class D--flammable metals--fire.What it WON'T be is a Class K--kitchen flammables--fire.In the air you'll just use your Class ABC built-in suppression system. If you land the thing on fire, they'll use Aqueous Film Forming Foam.
What is hydrocarbon fire extinguisher?
A hydrocarbon fire extinguisher is a type of fire extinguisher specifically designed to combat fires fueled by flammable liquids such as gasoline, oils, and grease. These extinguishers contain agents like dry powder or foam that work by smothering the fire and cutting off the oxygen supply to extinguish the flames.
What puts out a napalm fire?
Napalm fires are typically extinguished by smothering the flames with sand, foam, or a fire-retardant chemical agent. Water may spread the napalm fire due to its flammable properties, so it is not recommended for extinguishing napalm fires. Additionally, professional firefighters with appropriate protective gear are needed to handle napalm fires safely.
What type of foam is used to extinguish a polar solvent fire?
Alcohol-resistant foam is typically used to extinguish fires involving polar solvents, such as acetone or methanol. This type of foam forms a barrier between the fuel and the oxygen in the air, smothering the fire and preventing reignition.
Can blood put out a fire, or is it not an effective extinguishing agent?
Blood is not an effective extinguishing agent for fires. Water, foam, or chemical fire extinguishers are typically used to put out fires.
What would happen if you used a foam fire extinguisher on a liquid fire?
Using a foam fire extinguisher on a liquid fire can be effective, as foam is designed to smother flames and create a barrier between the fuel and the air. However, it's crucial to ensure that the liquid is compatible with foam extinguishing agents, as some flammable liquids may react adversely. If the foam does not properly cover the fuel, it might spread the fire instead of extinguishing it. Always check the fire classification and use the appropriate extinguisher for the specific type of fire.
What type of fire extinguisher can create a corrosive compound when discharged?
Class D fire extinguishers, which are specifically designed for use on flammable metal fires, can create corrosive compounds when discharged. The extinguishing agents used in these extinguishers, such as certain powders, can react with metals like sodium or potassium, leading to the formation of corrosive byproducts. It is crucial to use the appropriate extinguishing agent for the specific type of metal fire to avoid dangerous reactions.
What is the most effective method for extinguishing an oil fire?
The most effective method for extinguishing an oil fire is to smother it by cutting off its oxygen supply. This can be done by covering the fire with a fire blanket, sand, or a specialized foam designed for oil fires. Water should not be used to extinguish an oil fire as it can cause the fire to spread.
Which type of fire extinguisher is recommended for extinguishing a metal fire?
A Class D fire extinguisher is recommended for extinguishing a metal fire.
What are the consequence of in foam incorrect fire extinguisher on fire?
Using an incorrect fire extinguisher, such as a foam extinguisher on a fire involving flammable liquids or electrical equipment, can worsen the situation. Foam extinguishers are not suitable for electrical fires, as they can conduct electricity and pose a serious risk of electrocution. Additionally, applying foam to flammable liquid fires might spread the fire instead of extinguishing it, leading to larger flames and increased danger. It's crucial to use the appropriate extinguisher type for the specific fire class to ensure safety and effectiveness.
What is blanketing of fire?
Blanketing of fire refers to the method of extinguishing a fire by covering it with a material that deprives it of oxygen, thereby smothering the flames. This technique can involve using fire blankets, foam, or other materials to create a barrier between the fire and the surrounding air. It is particularly effective for small, contained fires, such as grease fires or fires in confined spaces, where traditional extinguishing methods may not be suitable.
Is carbon dioxide the only gas that extinguishes burning?
No, carbon dioxide is not the only gas that can extinguish a fire. Other gases such as water vapor, nitrogen, and certain types of fire extinguishing agents like halon and foam can also be effective in extinguishing fires by either displacing oxygen or cooling the fuel source.
Which type of fire extinguisher is recommended for extinguishing wood fires?
A Class A fire extinguisher is recommended for extinguishing wood fires.
How does fire go out?
Fire goes out when one or more elements of the fire triangle (heat, fuel, oxygen) are removed. This can happen through extinguishing methods like smothering the fire to remove oxygen, cooling the flames to reduce heat, or removing the fuel source to starve the fire.
What class of fire extinguisher is suitable for extinguishing fires involving magnesium?
A Class D fire extinguisher is suitable for extinguishing fires involving magnesium.
Where is a labs fire extinguisher located?
Laboratory fire extinguishers shoud be located just inside each exterior door. To be as safe as possible they should probably be of the type AR-AFFF, that is Alcohol Resistant Aqueous Film Forming Foam. While these foam extinguishers are messy they extinguish the fire AND THEN they provide reflash protection. Other extinguishing agents will extinguish the fire but if all the elements of a fire are still there, oxygen fuel and temperature, then the fire can reignite. AR-AFFF prevents that and prevents the foam from degrading due to solvents which tend to be present in Laboratories.
