Yes.
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 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.
What is a continuously burning fire?
A continuously burning fire is a fire that has a fuel source that allows it to keep burning without extinguishing. This can be achieved through a consistent supply of oxygen and fuel to the fire. Maintaining a continuously burning fire requires careful management and monitoring to prevent it from spreading uncontrollably.
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 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.
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.
What is the best extinguishing agent for the oil fire?
water
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.
Is foam a good use for oil fires?
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.
Where do you aim a fire extinguishers stream when extinguishing a fire?
At the base of the fire and use a sweeping motion
How do you stop spreading fire?
For each fire and material exist a specific fire-extinguishing method.
