Churches and Schools
Wiring found in churches and schools is most often constructed with higher capacity wiring and more rugged devices than residential structures. Because churches can accommodate a large number of people, most electrical and life safety codes have special requirements. Generally, these requirements recognize that in an emergency, a high occupancy building will take longer to evacuate than a residence. The plastic-covered cable that is typically used in homes is generally prohibited in places of assembly. Wiring should be metal-encased. While considerably more expensive, this wiring doesn't create as much toxic smoke when it burns, giving extra time to safely evacuate.
To speed up the process of emergency evacuation, churches and schools should also be equipped with emergency and exit lighting. These units are located to safely direct occupants to the nearest exits while providing constant illumination of the exit paths - even when the power may have failed in the building. It is also important that these safety devices be tested and maintained.
Most codes often require churches and schools to be covered by a fire detection system. In the case of schools, the fire alarm must automatically notify the fire department as well as alert all building occupants of a fire hazard. Again, periodic testing is required to ensure that the system would operate in a crisis
