Took my space cadets out for a tour of our local Defense Fire Service unit. At the end of the standard "fire extinguishers and how/when to use them" brief (water, CO2, foam, Dry Powder variants), I stoody up and said - trying to prompt the fireman,
"Of course, as Air Cadets, there is one other type of fire extinguisher that you will come accross in your activities - it is not generally available (indeed, it is now illegal except for use in aircraft)... It has a green label. Any one know what it is?"
The chief stared blankly at me, open mouthed.
He had no idea we still used halon, wondered why we couldn't use CO2 or dry powder...
