Fire Extinguishers

A fire extinguisher is primarily considered pneumatic, as it uses compressed gas to propel the extinguishing agent out of the nozzle. The pressure inside the extinguisher is created by gas, which can be either stored under pressure or generated through a chemical reaction. While hydraulic systems also use fluids under pressure, fire extinguishers do not rely on liquid pressure to discharge the extinguishing agent.

Every family should create and practice a fire escape plan that includes multiple exit routes from each room and a designated meeting spot outside. They should also install smoke detectors on every level of the home and test them monthly, ensuring that batteries are replaced regularly. Additionally, families should consider having a fire extinguisher accessible in key areas, and educate all members about fire safety and prevention measures. Regularly reviewing and updating these preparations can significantly enhance safety during an emergency.

House fires can be categorized into several types based on their causes. Common types include kitchen fires, often sparked by unattended cooking or grease; electrical fires, which can result from faulty wiring or overloaded circuits; and heating-related fires, typically caused by space heaters or improper use of fireplaces. Additionally, smoking materials and candles are frequent culprits in residential fires. Each type emphasizes the importance of fire safety and prevention measures in the home.

B-I and B-II refer to the relative fire extinguishing capacity of approved USCG fire extinguishers, depending upon the type of extinguishing agent used.

Class B fires involve flammable or combustible liquids such as gasoline, kerosene, grease and oil.

The numerical rating BEFORE the letter B, for class B extinguishers, indicates the approximate number of square feet of fire it can extinguish (i.e., with no significant depth).

The numerical rating (I, II, III) AFTER the letter B indicates Coast Guard classification. For example, a UL 5-B:C, rated for 5 sq ft of liquid fire, would be a USCG B-I extinguisher (with 2 pounds of dry chemical).

To obtain a USCG B-II rating you would need the equivalent of 10 pounds of dry chemical, such as having two UL 3-A, 40-B:C extinguishers, or a 15-pound CO2 extinguisher, or 2 1/2 gallons of AFFF "foam" (UL 3-A:20B).

A 20-pound dry-chemical (120-B:C) would meet USCG B-III requirements.

USCG ratings go as high as V, which is a big extinguisher on wheels.

Fire extinguishers have exoskeletons? Usually they're called canisters, cylinders or whatever. The thickness is determined by how big it is, because the larger it is the more pressure it must hold in. A really small extinguisher has metal about as thick as a soup can. A huge extinguisher can have 5mm thick walls.

B-number ratings are used by the US Coast Guard regulations to identify the necessary capacity of a fire extinguisher, depending upon the type of extinguishing agent used. Only extinguishers meet all USCG requirements can say "USCG approved".

Class B fires involve flammable or combustible liquids such as gasoline, kerosene, grease and oil.

The numerical rating BEFORE the letter B, for UL ratings of class B extinguishers, indicates the approximate number of square feet of fire it can extinguish (i.e., with no significant depth).

The numerical rating (I, II, III, IV, V) AFTER the letter B indicates Coast Guard classification. For example, a UL 5-B:C, rated for 5 sq ft of flammable liquid fire, would be a USCG B-I extinguisher (with 2 pounds of dry chemical).

To obtain a USCG B-II rating you would need the equivalent of 10 pounds of dry chemical, such as having two UL 3-A, 40-B:C extinguishers, or a 15-pound CO2 extinguisher, or 2 1/2 gallons of AFFF "foam" (UL 3-A:20B).

A 20-pound dry-chemical (120-B:C) would meet USCG B-III requirements, 30 pounds for B-IV and 50 pounds for B-V. Similarly, carbon-dioxide or foam-type extinguishers of various capacities fall within USCG ratings (e.g. 4 pounds CO2 for B-I, 15 pounds for B-II, etc).

Fires involving live electrical equipment.

A fire extinguisher does no make dry ice. Dry Ice is the solid form of the gas Carbon Dioxide. At room temperature is you compress (and cool) CO", it turns into solid CO2 (dry ice) without forming a liquid phase.

A FM200 gas is a solvent condensed gas and is without any hue. The gas is typically stored as a fluid and distributed into a hazard box. The solution is used for fire application protection, which is found in a fire extinguisher.

Acid can corrode the metal shell of the extinguisher. When it is rapidly pressurized, it may explode. They are no longer an approved extinguisher in many nations.

A quick Google search for Fire Extinguisher Training turns up a ton of results. Finding computer-based (CBT) courses is a little trickier. I personally think Convergence Training makes nice computer-based training modules. Here's their Fire Extinguisher course:

In MOST burning liquids, the water will sink, creating an explosion of steam as it become super-heated, causing the fire to spread rapidly.

Some aqueous film-forming fire extinguishers generate a foam that floats on the surface, smothering the fire.

Check it on images. Hope this help you!

All extinguishers should be professionally inspected annually. Call your local fire department business number for advise on finding a reputable local inspector.

Refilling or recharging should be done by, and on the advice of, a professional.

just roll them into the fire and they'll be fine;)

It does not.

Technical input: compressed CO2 might be in liquid form INSIDE the fire extinguisher because it is under more than about 5 atmospheres of pressure.
