Direct answer
First rule out immediate gas, fire, electrocution, and contaminated-water hazards. Do not test appliances one by one inside a damaged building.
Start here
Confirm people and exits are safe, then look from a distance for downed wires, sparks, smoke, leaking water, broken pipes, and gas odor. If gas is suspected, do not switch lights, use flame, or make a call inside; leave and contact fire or the gas utility from a safe place.
Work through the decision
Do not touch wet equipment, a damaged panel, or exposed wiring; wait for the utility or a qualified electrician. Use drinking water only under local utility guidance; follow boil-water or alternative-water directions after pressure loss, discoloration, or sewage backup.
Common mistake
Repeatedly testing valves or appliances, running a generator indoors, and tasting food to judge safety can create new hazards.
When to stop and get help
Evacuate for a continuing leak, fire, energized water, carbon-monoxide symptoms, or an inaccessible shutoff, and leave the work to emergency services.
Next step
Note utility status and shutoff time, keep refrigerator doors closed, and use battery radio or official channels for updates.
