WATCH this before using a CO2 fire extinguisher!!!

This quick and simple guide covers the basics about Carbon Dioxide Fire Extinguishers. These are very capable extinguishers for flammable liquids and electrical fires, but there are some safety tips you should be aware of.
For more detailed information please see our CO2 information post, including how to safely use it on our website: firesafetystic...

Short, simple, and straight to the point.
Excellent work, sir.

I find this video very helpful. Interesting how the UK and US use different letters to describe the type of fuel in question. Unlike the UK that uses A, B, C, D, Electrical, and F, here in the US we have 5 classes, A, B, C, D, & K, flammable liquids and flammable gasses are class B in the US. To make it easy for us to choose the correct extinguisher we used the following acronyms. A ‐ Ashes. B - Barrels. C - Circuits. D - Dynamite. K - Kitchen.
CO² extinguishers are found extensively in industrial settings where significant quantities of flammable liquids are used and stored. And because it's non conductive and doesn't leave a residue behind, it also finds widespread acceptance in engine compartments on ships, aircraft and some large trucks, and in data centers, server rooms and similar locations with expensive and sensitive assets. CO² is often ineffective on class A fires because any glowing embers usually results in re-ignition when the CO² dissipates, this fact prevents it from obtaining an A rating. The higher temperatures and flashpoints of vegetable and animal oils and fats used in deep fat fryers also make CO² ineffective on a class K fire for much the same reason. CO² is extremely dangerous when applied to a class D fire because combustible metals burn at temperatures much hotter than othr fires, typically anywhere from 5,000 to 8,500°F and these temperatures separate the carbon and oxygen molecules, adding more oxygen to the fire. Water separates into hydrogen and oxygen, causing violent explosions.
For most homes and businesses across America the most common fire extinguisher we see is the multipurpose dry chemical ABC type because that covers pretty much any type of fire likely to occur. In areas with D or K fire hazards such as metal fabrication shops, laboratories or commercial kitchens, we typically see a class D or K extinguisher in addition to the multipurpose dry chemical ABC.

Thank you!

I have a question. What would cause the plastic sleeve around the braided discharge hose to literally shatter with explosive force? I suspect it could be the CO2 gas leaking in between the two, causing the sleeve to harden due to the extreme cold gas, and burst. But that is my opinion. We had such an event today during a fire training exercise. Fortunately no injuries, but the poor student got such a fright that he dropped the extinguisher. Needless to say we immediately stopped any further discharging. Thanking you in advance for your feedback.

What type of fire extinguisher shall i use if a person is self immolating in petrol or kerosene?

What happens if I spray my friends with it from a distance of 10 feet. It is a pressurized/liquid co2 fire extinguisher.
They should cool down on a hot day right.
