Everyone is given instructions on how to be ready for emergencies from childhood. Situations that have immediate and urgent effect to the environment, life, health, and property, are considered emergencies. An emergency may require assistance after the fact or intervention by government bodies to minimize negative effects. Emergency communication equipment is a common sight in these cases.
Emergencies can be grouped into natural or man-made. Natural emergencies are calamities like tornadoes, earthquakes, and typhoons. Man-made ones, on the other hand, include bombs, fires, riots, and terrorist attacks. Some government offices are responsible for defining the means to manage, communicate, and minimize death by using a number of equipment.
However, responders and government agencies aren't the only ones who should make use of these tools. Having the ability to receive and send details about an emergency can also be taken advantage of by families, businesses, and civilians. The proper information can make people believe that they have control of the situation, and can thus find ways to cope and survive.
There are various emergency communication types. These include short-wave radios, 2-way radios, repeaters, weather radios, radio dispatch and signaling equipment, repeaters, and cross link systems. These items are made to withstand situations where phone and power lines are not working.
Police, fire, and medical departments depend on having radio communication as a means of coordinating and pinpointing the proper location. Failing to communicate may turn life to death in some instances. Repeaters are useful in these specific agencies in cases where the phone lines aren't working and a time bound incident is present. Repeaters can be run in UHF and VHF bands, not easily water damaged, can record important messages, and can be run using electricity and batteries.
Mobile phones are definitely handy and most people own one, but it depends highly on the capacity of the network. Shut down broadcast stations and towers, and there's a high likelihood that signal won't be available. In situations where lives are in the balance, people will always contact loved ones, causing congestion in the networks, removing people's means to communicate with their families. In these cases, two-wave, short-wave, and weather radios can be very helpful.
A short-wave or amateur radio allows people to communicate through the use of radio waves. It runs on electricity, solar power, and batteries. People can exchange safe zones, changes in the situation, and updates if they have the correct frequency. Like short-wave radios, 2-way radios also make use of radio waves. These can be used by complete amateurs as they are easy to figure out and normally runs on battery. A major disadvantage, though, is that its use is limited by range.
Through the years, these are other forms of emergency communication equipment developed. An example is PA or public address systems often placed strategically in streets, public areas, and buildings. Through this, information is spread to a larger area. To address situations where hearing loss is possible, like during bombings, LED signs are put up in public areas. Other forms include virtual signs that appear in large projectors and voice systems similar to those found in military compounds and manufacturing sites.
