Hazards of exposed photovoltaic support piles

What are the safety precautions when working a PV system?

When working and operating any PV system, the safeguards described below should be heeded. The best safety method is an alert mind, a doubting nature, and a slow hand. Never work on a PV installation alone. Know the PV and associated electrical system before you start to perform work. Discuss the test goals and methods with your partner.

Can a roof-mounted photovoltaic system cause a fire?

Fires on roof-mounted photovoltaic (PV) systems are rare. When they do happen, however, a combination of electrical hazards, combustible components and limited access can result in significant losses. As the technology becomes more common, this paper discusses how building owners and occupiers should approach and minimise the risks of PV systems.

What are the risk defining characteristics of a PV system?

Such PV systems have three risk defining characteristics: (1) electrical components located in exposed and often hard-to-access areas; (2) additional combustible load increasing the danger of fire spread; and (3) electrical installations that are difficult to isolate, and which firefighters may be hesitant in tackling.

What is included in a PV system Hazard Course?

Course includes description of specific hazards, their frequent causes, and ways to prevent and avoid them. PV System Characteristics and Hazards section provides the background of PV system characteristics and relevant hazards involved with PV systems. Recommended safe-guards are provided.

How safe is a PV system?

This is sufficient current and voltage to induce injury under worst case circumstances. If an array consists of more than two modules connected in series, the shock hazard grows. When working and operating any PV system, the safeguards described below should be heeded. The best safety method is an alert mind, a doubting nature, and a slow hand.

Are PV systems risk free?

Already a common feature in many countries, PV systems will become increasingly ubiquitous, as authorities seek to hit ambitious carbon reduction targets. A safe, reliable source of power, PV systems, like any technology, are not risk free; and building owners and occupiers must understand and manage that risk.
