Batteries should also be replaced on a regular basis. If you are a parent, don't assume that you will always be with your children in an emergency. Make sure they know how to protect themselves if you are not available to help.

A major chemical emergency is an accident that releases a hazardous amount of a chemical into the environment.
Accidents can happen underground, on railroad tracks or highways, and at manufacturing plants.
These accidents sometimes result in a fire or explosion, but many times you cannot see or smell anything unusual. In the event of a major chemical emergency, you will be notified by the authorities. To get your attention, a siren could sound, you may be called by telephone, or emergency personnel may drive by and give instructions over a loudspeaker. Officials could even come to your door. Your life could depend on it.
