I found this old posting, I think it was from Sir. Ed Koeffman,
concering using a CO2 extinguisher for the firefighting contest:

> As previously mentioned, I used a CO2 extinguisher. 
> This worked much better than expected. A
> two second blast blows out a row of candles two feet
> long at a distance of four feet! 
> I was fortunate to find a hefty CO2 cylinder that came 
> with a handle-operated control valve. The
> extinguisher (with valve) is 7" long and 1 1/4" in 
> diameter. The cylinder holds 38 grams of CO2,
> enough gas for 10 seconds of operation. The 
> cylinder was originally sold as a duster and is
> available from Hosfelt Electronics (800.524.6464) 
> for $15 (cylinder and valve) or $5.50 for a
> replacement cylinder.
