Emergency evacuation sirens are an important part of emergency preparedness for many reasons. First, they allow people to be alerted if a fire breaks out or if a home is on fire while they are still inside. If people hear an audible siren and act immediately, it can help stop the fire from getting out of control. They can also be used to summon help in case of flooding in the home or apartment.
Second, the sirens are also used to summon help for a fire in progress. If people find that they cannot get out of a certain room due to the fire, the siren can be used to alert people to evacuate the room. The emergency siren is not only used for emergencies, though. There are times when regular household items are in danger, and the siren is used to make sure that people know the situation.
