Check for sewage and water line damage . If you suspect damage, avoid using the toilets and call a plumber. If water pipes are damaged, contact the water company and avoid using water from the tap. You can obtain safe water from undamaged water heaters or by melting ice cubes. Check your home's structure - look for cracks in fireplace chimneys.
Cracks can be the cause of a fire years later.
Check your home's foundation to see if there has been any damage. Clean up spilled medicines, bleaches, gasoline or other flammable liquids immediately. Open closet and cabinet doors cautiously. Contents may have shifted during the shaking of an earthquake and could fall, creating further damage or injury. Help neighbors who may need special assistance.
