Disasters and danger come in all shapes and sizes. Tornadoes and tsunamis, earthquakes and volcanoes, bombs and gunmen to name but a few have sadly become a part and parcel of everyday life. If you live in Syria or Somalia for example you may be in constant danger and therefore always alert. If you live in Europe or America you expect your government to protect you to a large extent and warn you in advance of any unfolding calamity. And so there is a call for emergency communication equipment Pennsylvania area and anywhere else disaster may strike.
Despite the advances in communications with the advent of computers and mobile phones, both have inherent problems in an emergency situation. Social media may well be able to foment the odd revolution but networks do get overloaded when panic sets in and then, like television which can also be an important vehicle for mass communication, they depend on electricity, cables and transmission towers none of which might be functional.
Television and radio can also be used to disseminate information to large numbers of people but again depend on power and cable for the most part. A battery powered radio is, however, often recommended for those who live in war zones or areas prone to natural disasters. This allows them to receive, for instance, instructions to evacuate.
Sirens or hooters are good but people must know exactly what they mean and what action they must take. Rather like the fire alarm drills often visited on school children or the notices pinned behind hotel room doors which no one ever reads. In days gone by church bells were rung if the marauding tribe from the neighboring valley was seen riding through the pass.
Perhaps surprisingly, amateur radio operators have come into their own during several recent crises due to their ability to keep in touch with each other and some of the emergency services. The services themselves really rely on 2-way radios. These are battery operated and simple to use though generally speaking effective only over short distances.
The State of Pennsylvania is aware of its responsibilities towards its citizens. It has therefore set up an Emergency Alert System using satellite based technology known as EMnet. This is linked to television and radio stations and facilitates the distribution of early warning or emergency alert. They have also established an Auxiliary Communications Service with the help of volunteers like amateur radio users.
Not all disasters demand satellite communications however. Often a mobile communication truck or digital radios are more than sufficient to handle a localized emergency. And mobile phones and television will probably still be functioning.
One major problem is making people believe that they are faced with a disaster. They may think it is a hoax if they receive a text message about, say, a freak storm if such things do not usually happen. Public address systems can help a lot in these situations and are part of the emergency communication equipment Pennsylvania area.
