Stay outside rooms where standing water may contact outlets, cords, or appliances, and call from a dry location. CDC flood safety guidance advises switching off power only when the main switch can be reached without entering water. An electrician should handle a switch that requires crossing a wet area.
If a plumbing leak is active, close the water shutoff only when you can reach the valve safely. Leave immediately if you smell gas; contact emergency services from outside. Keep children and pets away from floodwater or drain backups. Do not run a household vacuum or place a fan in standing water. Avoid walking beneath a sagging ceiling.
Describe the hazards during the call so the inspection accounts for them. The water damage first steps provide further safety guidance.
