Automatic Fire Extinguisher

anyway, my creaking memory bank has finally remembered why I started on this thread...

www.pyrogen.co.uk

as used by the RNLI?, no idea of the price though, and no connection to the company.
 
Spare a thought for the poor buggers who died in the Russian sub when they fired off their freon by mistake. I was in a module offshore some time ago when the halon let loose... not a pleasant experience.

That's where foam and Halon (yes, I know we aren't allowed to have it any more) excel, as compared with CO2 and powder. With the former two, once it's out, it's out

Shuuussshhhh - I have a modern replacement extinguisher, but I have kept my old Halon ones hidden - but to hand.... A little rubber hole in the side of the engine compartment - and hey presto - job done....
 
Please consider purchasing a fire extinguisher manufactured in the UK and carries a kitemark

In respect of cost would you buy the cheapest parachute

Actually I did, several times. First thing you do is pop it and have it packed by an expert packer. Adds £50 to the price but you know its right /forums/images/graemlins/smile.gif
 
The system should have an override switch so you can start the engine if you decide not having power is more risk than fire........in most situations I can think of I'd rather have the fire out I think.
 
" Produced by Pyrogen Technologies, is now ISO 9000-2000 Certified"

OK. so the website isnt the greatest, try

www.pyrogen.com

is anything manufactured in this country anymore?
Given that the RNLI use it, I would be very surprised if its "cheap"!
 
I remember - near 30 years ago - being in the bowels of a very large OBO engine room (5 or 6 storeys up from engine plates to fresh air) when the CO2 alarm went off.
I have NEVER got up so many ladders so quick in my life.
It was a false alarm, but the fear and despair I felt then is not what I want to feel the day and hour that I know my passing has come, as those guys must have known.

I hope their God keeps them safe.
 
Blimey, didn't expect to start such a debate. The issue was raised, first by my wife; a reluctant sailor, then on the RYA Diesel Maintenance course where the instructor was adamant about auto fire extinguishers, hence my question. Given that powder makes an incredible mess and at sea, cleaning it up and restarting could be an issue, even a manual point and squirt gas solution will achieve the same results as an automatic. The only differences I can see, is that I am (1) likely to have shut down the engine before putting the fire out and (2) there is no chance of the surprise of an extinguisher going off accidentally.
I thank all of you who have contributed. I enjoyed the way the thread moved from a simple request to Russian submariners. May they rest in peace. Many thanks.
 
I would not have an automatic fire Extinguisher on my boat after I had one go off due to heat from the engine without fire.

I have fitted a smoke/fire detector with a remote operated Extinguisher.

This allows me to close down the engine in a controlled manor, close engine air vents and to operate the Extinguisher without opening the engine compartment. I also have a viewing port to see if fire is out again without opening engine compartment.
 
Northup suggested Pyrogen and altho' expensive it looks the answer. RNLI use them and I've had interesting conversations today with Pyrogen, SeaStart and the local RNLI and all claim you don't need an auto shut down and the pyrotechnic trigger will not go off under 79 degres c which is hot, I mean plastic melting hot so they should be OK, however I think your solution of a smoke detector (my new engine should have stopped smoking by now!) and a hand held is probably the answer.
Thanks to all of you for contributing to this question. I think a lot of people have learned something here, I know I have.
 
As a closure to this chat, I thought I'd add the response to my e-mail re engine shut down from Carl Shuker of Pyrogen.

Richard

One application of Pyrogen is Engine Strangling on test beds if Pyrogen is sucked into the engine it will shut it down without causing damage to the engine itself. Therefore when sizing a system the volume of the engine is generally added to the net volume of the engine space to allow sufficient extinguishing agent in the area. As for any extinguishing agent being used as fuel by thier very nature they are non flammable and non combustible agents.

THe MCA design requirements for Pyrogen is 100g per M3, actual test data suggests that less than 60g is sufficient to extinguish surface class A and B fires, so by very design there is an overkill to reduce the possibility of re-ignition
