<<John's message
has triggered a prior question I've had... What is the best type of on
board fire extinguisher?
My limited understanding is that Halon (and/or
Halon substitutes) work by absorbing/consuming oxygen - which makes them
effective at extinguishing fires. However, it seems perhaps that isn't
something that I'd want to trigger when I'm still in the (sealed) cabin (since
I need the O2 as
well).
Thoughts/comments???>>
As of about eight
years ago when I last worked on fire suppression systems in military combat
vehicles, Halon was the only agent that could extinguish a fire and still leave
a breathable atmosphere. At the time, Halon was the only agent approved
for human occupied areas. Unfortunately it is an ozone depleting
substance, so non-occupied areas were being converted to other agents.
Halon was being recovered and banked for exclusive use in occupied areas.
Unless something new has come around in recent years, Halon is the only agent I
would discharge in a small confined space like a cockpit.
