The accumulation of fumes from their use can be deadly. Do not use your telephone except for genuine emergency calls. If you have a chimney check its entire length for cracks and damage, particularly in the attic and at the roof line. Unnoticed damage could lead to a fire or collapse in aftershocks. The initial check should be made from a distance.
Approach chimneys with caution.
Check closets and storage shelf areas. Open closet and cupboard doors carefully and watch for objects falling from shelves. Do not spread rumors. They often do great harm following disasters. Tune-in to local radio stations for information and danger reports.
