The number of high rise builings in London (and the rest of the UK) isn’t significant to the Air Cadets, as we don’t parade in high rise builings.
As to the minimum written standards we should adhere to:
Each squadron should be inspected by DFRMO and a fire risk assessment produced by them.
We should carry out fire drills with a minimum frequency of 1 every 3 months.
We should test the emergency lights once a month*. My lights have a maintenance contract in place through RFCA.
The FAFAs should be visually inspected once a month. FAFA should be serviced yearly, and replaced if needed.
The fire alarm should be tested weekly, and if you have an electronic system, you should rotate which call point you use. My alarm has a maintenance contract in place, through RFCA.
We should receive training in FAFA, but since our official guidance is to not attempt to fight the firearm, I’m guessing that the cost of providing training is prohibitive.
Monthly inspections of the building to take place, looking for building waste paper or other fire hazards.
As I’ve said, although not particularly onerous, I personally disagree with OCs taking responsibility for the hardware, especially since if there is a fault, we can do nothing to remedy it.
*Emergency lights should stay illuminated for 4 hours, but I’ll be blowed if I’m sitting in a building with no electricity for 4 hours once a month!
