Wear protective masks regardless of ventilation conditions in building. Turn off ventilation systems. Rooftop PV systems may fall inward after the roof under the systems is damaged.
UL studies have indicated that a solar PV system can generate enough DC electricity to present an electrical shock hazard. This has led to changes in firefighter safety procedures related to solar PV during periods of darkness at a working fire or an emergency scene.
Solar PV systems can present a danger due to having two electrical power sources for one building: the traditional AC electrical service provided by the PG&E power grid and the secondary electrical power source from the solar PV system.
This hazard grows if the support beams are weakened during a fire. The modules could also fall during the fire, endangering both inhabitants and first responders. Be careful during the designing process and consult with the structural engineer if necessary. Always inform firefighters of the presence of a PV system on the roof. 4.
Properly installed and undamaged PV arrays are not hazardous. The relative simplicity of PV systems makes hazards easier to predict and avoid. New technologies need to be demonstrated to be effective under the conditions in which the PV system is improperly installed or damaged.
Such hazards for firefighters caused by a rooftop PV system include: electrical shock, slips and falls, electrical arcing roof collapse, and fire risks from the PV materials. To protect firefighters and mitigate hazards, research and analyses are available to provide information on how to deal with PV components during and after firefighting.
