Thread: Fire extinguishers

Anyone seen something similar to these in NZ ?

looks impressive.
Keen to see em used on a decent fire though. Must be a catch, they seem too good to be true.

Yeah, looking for alternatives to the normal 1kg little powder ones. Mainly for the ute for off-road.

Used a 1kg powder one on the BBQ :-) Reasonably effective, but does not last long, and recharge cost is almost more than buying a replacement...

Who would have thought of fighting fire with KNO3?

See if you can talk your VSO into buying you a couple. For, err, recruit training or something.

Wow, that sounds cool. I hope they are as good as they claim.

they work, there are also spherical ones that fit in a metal hoop and have a fuse out the bottom, they spray a foam downwards and help stop the spread of flame. i have seen a few in server rooms etc.

Hehe, that brings up a whole other story. Back in the 80's when I started computer programming, we had a fire suppression system in the mainframe room. Unbelievably toxic stuff. When the alarms went off you had a couple of seconds to get the hell out of dodge before the gas was released. Let's just say they valued their mainframe more than the human operators and techies

Most likely Halon, for which there are huge exaggerations re how quickly it kills humans. Sucks up the oxygen etc was one of the classics. Sure you need to get out but more for the toxic shite that gets released by the fire. Is doesn't kill the fire by oxygen removal.

My old company had vast clean agent fire suppression systems throughout many electric rooms containing a lot of electronics including computers and drive systems. All protected by Halon deluge systems.

Air NZ and my old company were the only ones in NZ that had dispensation to continue using Halon beyond the prohibited date. I think now the old joint may have changed to HFC-227ea in recent years.

Unfortunately, Halon was/is one of the most effective fire suppressants around with mostly minimal damage to electronic equipment it protects. It is one of those gases that mangles the ozone layer, or so I am told.

its halon type BCF, its an oxygen depleter. used to be available in fire extinguishers (usually yellow) or even large aerosol cans sold in nz by selleys.
they work bloody well but upset the greenies no end

Nope.

"The common mistaken belief is that Halon removes oxygen from the air. However, the Halon Alternative Research Corporation suggests that the agent chemically reacts with all three components of a fire (fuel, oxygen & ignition source) and not by removing the oxygen."
