Chris,

Hangar fires, just by head:
- 30 June 1968 Hangar 10 at Amsterdam Airport
- 5 May 2006 Sabena Technics "hangar 40" at Brussels Airport.
With some googling you might even find more.
Or are we just living in a dangerous neighbourhood?

Met vriendelijke groet / Yours sincerely,

Forgot about that one. Navy and DLA yes, all others when the waters supply without the pump cannot do 25% of the design area.

The question surrounds why do the Code protect hangars so much differently than about everything else. Certainly a plane owner or insurance company might want to but where is the threat to the public or occupants that is so much greater which is where the codes should IMHO focus on. I'd also throw in the lack of known fires in hangars. The Air Force recently looked and couldn't find a single fire in the last 50 years as it was related to me.

I believe it's still required at military installations per the UFC where what's being protected and fed by the pump has been determined to be mission critical.

Can anyone definitively say where redundant fire pumps are required besides hangars per 409? I'm thinking maybe hospitals and high-rises or just super high-rises? I don't do enough of those to be sure. I'm asking required by Code not debating whether they are just a good idea in some occupancies.
