The closest fit for disaster stuff, I assume for building design for safety would be...fire protection engineering.

There are less than 10 programs in North America that specialize in this area...but that is based on my knowledge over 20 yrs. ago. This area of engineering covers structural, mechanical, electrical but with a fire safety building design focus. Usually the engineer stumbles into it when already they are in 1 of the other engineering areas.

Best programs have a Master's focus because after all the engineer in Canada must become licensed as a professional engineer and then later they can get the SFPE designation ....

Check web site for Society of Fire Protection Engineers.

I worked for a bunch of them for a provincial regulatory body on fire code enforcement and review. (I was responsible for a fire protection engineering library...of which less than 40 llibraries exist world-wide, but that was ages no. And no full-text books on this stuff is not free, not available on the open Internet. It never will be.)
