I think I read an analysis of causes of Central Office fires a few years ago, and the leading cause of fires was use of "unapproved food preparation devices" within the central office (e.g.: someone smuggled a hot-plate or microwave in).
I've joked that if I had my way, there would be no CNG lines within 1/2 mile of the DC, and no water except fire hydrants outside. Eyewash stations would be self-contained; water for the break room would come in carboys, and staff can relieve themselves in a Porta-John/Biffs outside, with hand sanitizer
