AUTO FIRE EXTINGUISHER FOR FRIG
John Hennessey:
Marc, do you have the 90 degree head? How would I mount it?
Joel Weiss:
After watching a demonstration staged by Mac the Fire Guy, we replaced our powder extinguishers with 3 aqueous foam ones (one large and 2 small). The ability of these units to deal with Class A and B fires is impressive and they don't have the residue issues associated with powder.
We're planning to buy a large automatic system for the engine compartment. Mac inspected both our electrical bay and generator compartment and didn't think either one warranted an extinguisher. I have to admit I hadn't considered the Hurricane system. We eliminated the refrigerator concern by buying a residential one.
John Hennessey:
We had a 53 foot boat that had a halon fire suppression system. It was huge and unfortunately my husband was down in the engine compartment and knocked it just a bit and it went off. So when you mount any auto system make sure nothing will accidentally trip it. The previous owner had a small engine fire and he said it worked great. The manufacture was KIDDE and they were bought out so we couldn't get it recharged. Halon extinguisher need to be refilled at the factory.

IMO a halon system wouldn't be suitable for a MH engine compartment because it the engine bay is open at the bottom. Halon is normally used in enclosed locations so it can displace oxygen and stop the fire. You could use it inside the coach but you wouldn't want to be inside if it went off. Your husband was very lucky; no one is supposed to be inside when a halon system is set off.
John Hennessey:
The ss-30 is advertised to be used in engine compartments. Aren't they open at the bottom? Also, our engine compartment wasn't totally closed. It had 2 3ft by 1 foot vents. The problem with other types of extinguishers is that they leave a residue and I would think that a CO2 extinguisher would be made less effective with an open compartment since the intro of oxygen via an open compartment or vent would be the same as halon. Halon is so much more expensive than CO2 (ours was 2K) for a fraction of the size that big tankers need that I suppose cost is a factor is which type to buy.
