Emergency water may be obtained from such sources as hot water tanks, toilet tanks, and melted ice cubes. Check to see that sewage lines are intact before permitting continued flushing of toilets. Check chimneys for cracks and damage. Unnoticed damage could lead to fire. The initial check should be made from a distance.
Approach chimneys with great caution.
Do not touch downed powerlines or objects touched by downed lines. Do not eat or drink anything from open containers near shattered glass. If power is off, check your freezer and plan meals to use foods which will spoil quickly. Stay out of severely damaged buildings. Aftershocks can shake them down.
