Not sure if this one is for the firefighters or EMTs.
If a person's clothing is on fire due to a flamable liquid spill, is there a reason NOT to use a dry chemical fire extinguisher to put the fire out?
I know about smothering a fire, stop, drop, roll, etc, but in the event a dry chemical fire extinguisher (ABC) were at hand and the fire were extensive enough, should it be used?
Or, should it be avoided at all costs?
Obviously, not to be used in a way that would inhibit breathing, the posibility of injestion, etc.

Curious as to what you think or have been trained to do.

Disclaimer: I'm not an expert on this subject.

Absolutely I think you should use a dry chemical extinguisher on a person. I've seen it done and the person suffered no ill effects.

It was a training class for military personnel who were being posted to a remote location. A senior NCO who obviously hadn't paid attention to the firefighters' verbal instructions walked straight up to a metal bucket filled with water and burning gasoline, pointed the extinguisher straight down, and let it go full force. In other words, he did everything we had just been carefully told NOT to do. The burning gasoline splashed all over his legs and feet, setting his trousers and boots on fire; he sprayed himself with the extinguisher before he could suffer any serious injury.

The one you shouldn't use on a person is the CO2 fire extinguisher; because of the extreme cold it generates, you can cause severe frostbite (or so I was told).

ABC means just that - it can be used on any type A, type B, or type C fire.

I am a firefighter.
The steps are now
DROP - ROLL - COOL
However, an ABC dry chem extinguisher is a great solution if the fire is not out.
