Canned Air Cylinders

[Captainron19]

Not sure just how true this is but email was forwarded to me regarding someone that sprayed some canned air in their SUV (The kind you can buy at an office supply store to clean computer equipment). Apparently, the man lit up a cigarette in the car a little later and had a explosion giving him first and second degree burns on the arms not to mention the damage it caused to the vehicle (see Pics Below).

Apparantly, the can of air (as seen below) contains Difluoroethane which is a flammable aerosol propellant as well as an asphyxiant. I also attached the fact sheet on Difluoroethane below which shows it as having a "Severe" fire risk.

Hello guys!

I have one of those cans of air that I can re-fill with my air compressor... what i don't
have is the propellant.

If you take the same volume of air, same pressure but add a propellant to one of the cans and not the other, I'm pretty sure one of the cans of air will propel the air out of the can
at a sustained flow rate.... while the one without the propellant will not be able to sustain
the flow rate.
