Staying safe after property damage

Electricity and standing water

Water and electricity are the most common hidden hazard after a loss. The CDC advises never switching power on or off, or using an electric appliance, while standing in water, and having a certified electrician inspect the property before power is restored. If you cannot reach the panel from a dry location, wait for a professional or your utility.

Floodwater and sewage

Outdoor floodwater and sewer backups are treated as contaminated. Keep children and pets away, wear boots, gloves, and eye protection if you must be near it, and wash thoroughly afterward. The CDC recommends discarding porous materials — such as drywall and insulation — that sewage or floodwater has soaked, because they cannot be reliably disinfected. Never use bleach in a closed space, and never mix it with ammonia or other cleaners.

Mold and moisture

Mold is a moisture problem. The EPA notes that drying wet materials within 24 to 48 hours usually prevents it. For existing growth on hard surfaces, the EPA suggests cleaning with detergent and water and drying completely, discarding porous materials that stay moldy, and considering professional help for areas larger than roughly 10 square feet or where sewage is involved. Judging mold by color is not reliable.

Returning after a fire

A fire-damaged building can stay dangerous after the flames are out. Wait for the fire department to declare it safe, do not reconnect utilities yourself, and treat soot as an irritant. Water left by firefighting should be dried to avoid a secondary mold problem.
