Before you enter a damaged building, check for structural damage. Make sure the building is not in danger of collapsing. Look for leaning walls, sagging roofs and ceilings, and weakened support columns.
- Wear sturdy work boots.
- Turn off any outside gas lines. Let the house ventilate for several minutes to remove escaping gas.
- Be sure all electric service is turned off before entering for the first time. If the main disconnect is inside the house, you should call your utility company for assistance. Even if power is out in your neighborhood, disconnect the main switch, fuse or circuit breaker at your home, and disconnect all circuits.
- When entering the building, don’t use an open flame as a light source; use a battery-operated flashlight. Do not smoke.
- Enter carefully. Walking surfaces may be slippery or uneven. Check for sagging ceilings. Wet insulation or pocketed water can cause ceilings to fall. Once inside, unplug all appliances that have been flooded. Remember that some appliances can shock you even after the power is turned off.
When you're ready to begin work, be sure to wear protective clothing and gloves. In flood-damaged homes, a mold mask is strongly advised.
