Use outdoor charcoal or propane broilers for emergency cooking. Do not bring these items indoors. The accumulation of fumes from their use can be deadly. Unnoticed damage could lead to a fire or collapse in aftershocks. The initial check should be made from a distance.
Approach chimneys with caution.
Open closet and cupboard doors carefully and watch for objects falling from shelves. They often do great harm following disasters. Tune-in to local radio stations for information and danger reports. Do not go sightseeing. Do not use your vehicle unless there is a genuine emergency.
