Fire Extinguisher Thought
« on: December 04, 2013, 08:24:59 PM »
I have a couple of old extinguishers.  A chemical one I have has lost all its pressure.  I unscrewed the top and found the powder inside is now a semi-solid.  I once looked into getting a Coldfire suppressor but never did.  As I understand it, one can buy Coldfire in a 13 oz aerosol can or can by the agent, which you then mix with water, and fill and pressurize the appropriate canister of your choice.

My thought was to empty out the expired extinguisher I have, drill it, install a Schraider valve, and use it to load the Coldfire agent.  What's wrong with that plan?

      If the extinguisher you have has a pressure gauge, and it holds pressure (the ColdFire might leak at a different rate to the more pressure it was made for), I can't think of anything.  I'd ask ColdFire technical service, tho.

Good suggestion although I would have expected that for liability reasons they would say absolutely no.  The guy I spoke to was very reasonable.  The problems that he brought up though dealt with the possibly different spray characteristics of the unit I was intending to use.  He was nice enough to offer to evaluate the unit for Coldfire use if I sent him a picture.  I may just put this on the back burner (pun alert) for now though.

Consider A Larger CO2 Extinguisher (Or Two) And Why?

Bigger might just be better, considering the application.  CO2 as it does not leave quite the mess. (which might be worse than the small fire)  Consider the largest one you can physically handle, (pick up and employ) plus consider mounting two (2) of them, one by the front door, and the other by the auxiliary door or secondary  escape route.  HB of CJ (old retarded firefighter coot) :)
