Battery-powered lighting is the safest and easiest, preventing fire hazard for the user, occupants, and building. Examine walls, floors, doors, staircases, and windows to make sure that the building is not in danger of collapsing. Look for fire hazards. There may be broken or leaking gas lines, or damage to electrical systems. Clean up spilled medicines, bleaches, gasoline, or other flammable liquids immediately.
Fire is the most frequent hazard following other disasters.
Check for gas leaks. If you smell gas or hear a blowing or hissing noise, open a window and quickly leave the building. Turn off the gas using the outside main valve if you can, and call the gas company from a neighbor's home. If you turn off the gas for any reason, it must be turned back on by a professional. Look for electrical system damage.
