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 either be man-made or natural. Natural emergencies include calamities like earthquakes, tornadoes, and typhoons. Man-made disasters include fires, bombs, terrorist attacks, and riots. There are government agencies who define how to communicate, manage, and mitigate loss of life during disasters through the use of different equipment.
Of course, these tools aren't just for the government and responders. Civilians, businesses, and families can benefit from having a means to send and receive information in times of disaster. Understanding the situation can help people feel more in control, and aid them in dealing with any disaster.
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.
To coordinate and be able to respond in the correct place at the right time, medical, police, and fire departments use radio communication. There are instances when the difference between life and death could be decided upon by proper communication. If a time critical situation occurs and there are no operable phone lines, agencies make use of repeaters. These can sometimes be used to record relevant information, can be operated using electricity or batteries, portable, accessible using VHF or UHF channels, and can withstand water downpour.
Although mobile phones are highly accessible and almost everyone has one, it is highly dependent on the mobile network's capacity. Take down broadcast towers and you highly reduce the chances of getting a signal. In emergencies where people's lives are at stake, people tend to check up on loved ones, congesting networks and leaving people with no means to contact their families. In cases like these, short-wave, two-way, and weather radios are a must-have.
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.
Over the years, other emergency communication equipment have been invented and made public. These include public address or PA systems that are strategically placed in public areas, streets, and buildings. This allows information to be disseminated over a large area. To accommodate situations where hearing may be impaired, like in places where bombing occurs, LED signs are posted in public places. Other forms of communication include digital signage that appear in huge televisions and voice systems like those in military facilities and manufacturing plants.
