FoolsHumor Posted February 4, 2014 Share Posted February 4, 2014 I have a couple of questions please in reference to the early fire extinguishers as used on Ferrets and I assume other vehicles as well. I have heard them referred to as Indian Club style and a photo of the bottle without the brass head is attached. Also 2 images of the threaded insert, one with it removed and upside down showing the spent pierceable copper disc. Can someone tell me what fire suppressant was used? There appears to be some yellow powder involved. More puzzling is how were they pressurized? No other one way valves or such is present. Were they filled with a chemical mix that somehow built its own pressure after the copper ring was seated? Forgive me if I have previously asked this. The memory is going quickly. Thanks for any help offered. Regards, Bob Quote Link to comment Share on other sites More sharing options...
Adrian Barrell Posted February 4, 2014 Share Posted February 4, 2014 They are Methyl Bromide extinguishers, only for external use as the fumes are poisonous. They came in at least two sizes, the larger, as used on vehicles, at 4 1/2" diameter and a smaller aircraft type at 2 1/2" dia. Quote Link to comment Share on other sites More sharing options...
