Fires are some of the most devastating kinds of disasters. They destroy everything in their wake including homes, businesses, possessions, cars, and sometimes they cause serious injuries and deaths. The earlier you detect a fire, the better your chances of survival are. Sometimes people make the mistake of trying to gather their belongings when a fire breaks out, but this is a really bad decision. As soon as you realize that there is a fire nearby, you should evacuate the premises. Your safety is far more important than any material possessions. Most items can be replaced anyway, but even irreplaceable things such as family photos are not worth losing your life for. Every company and home should have a fire alarm system installed as soon as possible. These systems monitor environmental changes like temperature and smoke in order to detect a fire rapidly. They usually emit very loud noises as a warning to anyone nearby that a fire has broken out. Since they are so noisy, they can be used to alert people that there is any kind of emergency such as an earthquake, robbery, or other disaster. These may also help the fire department and rescue services identify the location of a fire that may not be visible from the outside of a building.
