What is created when CO2 displaces oxygen in a fire extinguisher?
There is no chemical reaction involved. The CO2 simply acts like a heavy blanket, pushing the air from around the fire away. A more complex physical reaction happens as the CO2 is discharged: the sudden drop in pressure as the liquified CO2 expands results in a rapid drop in temperature, producing pellets of dry ice (solid carbon dioxide). The cloud you see when a CO2 extinguisher is activated is mostly water vapor condensed from the atmosphere by the cold gas.
What does ABC on a fire extinguisher mean?
that it has been tested to the NFPA 10/UL 711 standard and that it has passed the class A, B and C test requirements to be listed as such.

What does the letter B on a B-1 fire extinguisher indicate?
The B determines the type of fire that can be extinguished, and in this case it would be flammable liquids such as gasoline, grease, oil, diesel fuel, and kerosene.
The number indicates the approximate number of square feet the unit can extinguish, so a B-1 would be a relatively small extinguisher.
How often should you inspect fire extinguishers?
NFPA 1 (National Fire Code) requires that fire extinguishers be inspected every 30 days or less and maintained no less than yearly.
The annual maintenance, if any, depends upon the type of extinguisher and the conditions under which it is kept, among other things.
Can grease fires be safely taken out with water?
Absolutely not - water just spreads the grease and makes the fire worse. Smother a grease fire with an extinguisher or a pot lid or sand or baking soda.
How many fire extinguishers are requires for an 18 foot powerboat with installed fuel tanks?
At least one USCG-approved Class B-1 fire extinguisher is required on any powerboat, unless it is under the following exception:
- "motorboats less than 26 feet in length,
- propelled by outboard motors and
- not carrying passengers for hire, need not carry such portable fire extinguishers if
- the construction of such motorboats will not permit the entrapment of explosive or flammable gases or vapors" [bullets added]
A UL-listed 5-B:C extinguisher, with 2 pounds of dry chemical, may provide the basis for the extinguisher, but it must ALSO conform to USCG-approvals (proper corrosion protection, labeling, mounting bracket, etc).
If you have a fire the size of a fire pit what household items would put it out the fastest?

What are dry fire extinguishers designed to do?
ALL fire extinguishers are designed to put out fires. A Dry extinguisher uses a powder or gas rather than a liquid, and cuts off the oxygen to the fire. They can be used in freezing conditions where a water type extinguisher would be useless.

Why would someone use a dry powder fire extinguisher rather than a foam one?
A dry powder fire extinguisher is mostly recommended for use in vehicles and in the home. So basically they are usually used for small fire emergencies.
Do you need to re-fill CO2 fire extinguisher even though its not empty?
You should always recharge an extinguisher after any use, for two reasons: 1. Using the extinguisher can disturb the sealing on the valve, allowing the pressurising gas to leak away (this is particularly a problem with dry powder extinguishers). 2. CO2 extinguishers only discharge for about 12-15 seconds for a normal-sized unit: a half-empty unit leaves the user only about 6 seconds of extinguishing time. it's illegal to replace a half-used extinguisher in a public building in most areas.
How much flammable liquid will a 10 b fire extinguisher put out?

What types of fire extinguishers are safe to use on electrical type fire?

Some new fire codes (2011) require alarm monitoring of fire extinguishers, if an alarm system is already required in the occupancy.
Is a fire extinguisher the smae foam firefighters use?
No. Fire extinguishers use a dry powder to smother the fire. Firefighters use two types of foam that can be broken down into more categories.
A class "A" foam is actually a type of soap. It is used to break up water tension so that water can seep into the ground and/or fuel better.
A class "B" foam is used to make a blanket that smothers gasoline or diesel type fires.
