Halon 1211

Looking for business insurance I ran across an article with things you can do to lower your premium.

Setting up the maintenance in CMMS I realized we did not yet have a fire suppression plan for the enclosure.

My research led me to Halon 1211.

  • Halon is an effective agent on Class B and C fires, the ones you’re most likely to see in a simulator.
  • As a gas, it’s capable of getting into hard-to-reach places like the inner workings of your instrument panel.
  • It’s a non-corrosive clean agent, which means it won’t damage items it comes into contact with.
  • It won’t shock-cool your avionics.
  • It’s lighter and more efficient than CO2.
  • Halons are low-toxicity, chemically stable compounds.
  • It works in gas form, so it will not obscure your vision like the powder emitted from dry chemical extinguishers. Basically, it’s invisible.

The manufacturer recommends 1 pound of Halon 1211 per 140 cu. ft. of space.  I found 1.25 pound units (too small) and 2.5 pound units for about the same price.

I also inquired about using automatic discharge 165°F units about the efficacy and availability.
