fire extinguishers are pretty high pressured already, so why not make it so that at a specific temperature (a high one, the kind found in fires) the canister explodes? this would distribute fire extinguishing chemicals throughout the flaming area. with a little engineering, this could be geared to affect the ones in glass cases, so that they could blast through the covering.

effective in instances when poorly monitored buildings burn down, or when anyone who could use it has simply skedaddled to avoid the raging inferno.

Then they are recalled. [2 fries shy of a happy meal, Oct 04 2004, last modified Oct 05 2004]

Oh the irony. To barely make your way through a burning building, the wet towel over your head burning your scalp with steam and beginning to blacken at the edges. You can see daylight, just five more steps to sweet cool smokeless air. Now two. When BLAM! You’re blown to flinders by the fire extinguisher.

Isn't activation at specified temperature what automatic fire sprinkling systems are designed to do? Why rely on cabinet mounted cylinder portable extinguishers when ceiling-mounted plumbed units are so much more effective?
