make fireextinguishers burst if they get too hot?

Have the fire extinguisher explode like a frag grenade.  It's contents become an aerosol dispersal in double the radius of what it would have pooled in.

Makes it less of a pipe bomb, and more of a minor chem grenade with shrapnel.

Edit: Extinguishers left in an area that gets too hot would then also explode, releasing their foam.  Might help fight the fire.  Might just injure the unwary scientist in toxins.  Huffing fire extinguisher fumes isn't healthy IRL, so maybe have it do lung and random organ damage to still keep it with some odd use as a weapon?

So like, the fire extinguisher doesn't actually explode explode so much as all the contents get smoked out?
