The answer
Protect people first. Leave and call 911 for immediate fire, gas, electrical, structural, rapidly rising water, or other danger; use 311 and utility or qualified response channels where appropriate. Do not enter contaminated or unsafe areas. Once safe, stop the source only if you can do so without risk, photograph original conditions, contact the insurer, record every instruction, and authorize only necessary emergency stabilization with a written scope.
