Quoted from 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.

The extinguisher Mac recommends for engine compartments is foam, not CO2. CO2 wouldn't be effective for the reason you note. The foam leaves only a water soluble residue which can easily be removed. We watched foam be demonstrated against a variety of fires, particularly gasoline and diesel fuel. It provides protection to vertical surfaces for a considerable length of time. An engine compartment unit is supposed to be positioned over the intake side of the engine so that the spray from the nozzle can blanket the surfaces on that side.

This link this talks about a question I had on fire extinguisher placement in the refrigerator compartment.

Thoughts?

Thanks for the link, Wayne. Another link within an associated thread led me to this very interesting YouTube post, where you can learn something about your refrigerator's construction, as well as see an appropriate mid-level fire extinquisher placement that would deal with both top and bottom compartment fires, but leave the extinguisher tank and guage fully accessible.

This thread got me thinking, worrying and then pondering the installation of these automatic extinguishers; so many things to look into and learn.

Well, I found a problem after contacting a local fire/safety supplier and was told that Halon 1211/1301 is illegal in Canada unless special arrangements and licensing is in place, and then only for aircraft applications.

So I am trying to find something comparable. Any ideas?

The engine suppression system Mac The Fire Guy sells is a foam based system, correct?

Thanks,

Jeff

This thread has brought me into the whole fire safety in the RV mode. It would appear proper attention to maintenance of heat generating systems is a key factor. Then what fire controls to put in place, ranging from smoke detectors and fire extinguishers to fully automated fire suppression systems. As well as having a fire escape plan and practicing it. I'm still in the processing mode at this time. I did find the videos on "cold fire" in this link interesting http://www.coldfire.biz/CF_Video_News.htm .

I can't get your link to work. Did you intend to point here: http://www.firefreeze.com/ ? These folks appear to own the trade name "cold fire".
