I've made a career of breaking planes, not fixing them, so I'm not too familiar with these maintenance hangar fire suppression systems. It seems from the news accounts I've found online there is usually a 30-second warning period for folks to evacuate before the foam starts to flow. Is there no cancellation available? Or does the override stop the foam rather than start it without detection?
I remember doing a sim somewhere with the briefing that a halon or something similar cloud would fill the bay in event of a fire detection. I was told that if I didn't get out I would suffocate (but be pay protected for the remainder of the training session under the CBA
).
