Can firefighters work near energized PV systems?

As PV deployments have become commonplace around the world, codes and standards bodies have worked with the fire services and the PV industry to develop guidelines to address the potential hazards to firefighters working near energized PV systems.

Can a PV system be used near a fire?

The presence of a PV system near a fire may produce hazards such as heightened potential for falls, electrical shock, and collapse of roof structures. Due to these perceived hazards, there have been cases where firefighters limited their operations and the fire was allowed to expand.

How do you prevent a fire from installing a PV system?

Identify structures with PV systems installed. Minimize potential hazards in firefighter operations (e.g., ensure sufficient working space and mitigate electrical shock hazards). Prevent/contain fires originating from the PV system. Implementing technologies to minimize potential hazards from PV systems (technology implementations).

How can a PV system improve firefighters' safety?

As main activities to improve firefighters’ safety, the German guidelines explain the importance of recognizing PV systems, installation methods of DC wires to lower electric shock risks for firefighters, and a specific firefighting operation flow for fires involving PV systems.

How do ICS deal with fires involving solar PV?

“Big box” buildings may require the IC to think “outside the box” when tackling fires involving solar PV. Consider horizontal ventilation techniques using the large receiving door openings for ventilation and special call equipment as an aid (e.g., cranes, claws, lifts, and so on).

Can a fire department disconnect a PV system?

Disconnecting PV systems should normally not be left to the fire department. 23. PV systems should only be installed and commissioned by qualified contractors. Training courses and certification processes are available. 24.
