BCF = Bromochlorodiflouromethane. So there!!!!
Yes Alan, we used to have it in all our vehicles, cars and lorries alike. (MOD).
The CO2 and the Dry Powder extinguishers we used outside on Airfields and were use to knock out fires inside aircraft engines by piercing the metal casings with a sharp pointed hollow lance where the chemicals were then fired into the wings or fuselage. Then again both the CO2 and the Dry Powder were in 47Kg Cylinders and mounted 6 to a trailer.
Our Foam came either as Animal Blood or Chemical. The Chemical stuff being a tad less smelly than the other stuff!!! This was generated directly from the water tank on the Pump.
We also had foam generators that could be used to fill a ships hold in about a minute.
One day while practising with the foam generator on an old house, we filled all 4 floors until the foam was spouting out through an attic window. The following day we went back to see what was what and found to our amazement that the foam had stripped the wallpaer off of every wall and it was all lying in little bundles along the skirting boards.
Anyways, a few months later a member of the crew noticed that a frustrated neighbour of his was struggling to remove his wall paper in his lounge and told him that he would "borrow" this fantastic stuff that he had in work and they would brush the offending paper with this magic paper remover.
Well all went according to plan, the paper was found the follwing morning on the floor as expected and the guy duly washed down the walls, repapered and went to bed pleased as Punch.
However he was not so pleased the next morning to find his new paper lying on the floor in little bundles. Indeed eventually he had to seal his walls with paint before he eventually got some paper to stick to his walls. Some things are not as Magic as they first appear.
Someday I will tell you about a terrific wheeze that you can do with the chemicals of a foam extinguisher!!!
