Main risks

• Falls and injuries during work at height on roofs or elevated structures.
• Impacts or entrapment when handling heavy panels, rails and anchors.
• Cuts from metal edges, swarf or tools.
• Electrical hazard due to proximity to energised modules and DC connections.
• Fire or overheating due to pinched cables, abrasion or loose connections.
• Water ingress due to poorly sealed roof penetrations.
• Detachment or instability due to insufficient anchoring under wind or snow loads.
• Corrosion and material degradation due to dissimilar metals, saline or chemical environments.
• Damage to the building structure when drilling in unsuitable areas or into concealed services.
• Additional risks from adverse weather (high winds, rain, ice or thunderstorms).

Safe use

• Verify that the structure and accessories are compatible with the roof/ground type and the intended loads.
• Plan anchorage points and weight distribution before starting; keep the work area tidy and free of obstructions.
• Use appropriate personal protective equipment (PPE): helmet, cut-resistant gloves, safety glasses, non-slip footwear and a fall-arrest system when working at height.
• Work with the photovoltaic (PV) generator de-energised whenever possible: cover modules, lock off isolators, and do not connect or disconnect under load.
• Follow the assembly sequence specified by the manufacturer; use appropriate tools and tighten fasteners without exceeding the recommended torque.
• Use compatible fixings and accessories; avoid mixing dissimilar metals that may cause galvanic corrosion, and use insulating washers or isolators where appropriate.
• Before drilling, check for hidden cables, pipes or other services; seal penetrations to maintain weathertightness.
• Manage cabling with UV-resistant ties and clips; protect sharp edges, observe bend radii, and avoid moving or hot areas.
• Maintain ventilation clearances beneath the modules and do not step on the panels; use walkways or suitable supports.
• Suspend installation in high winds, rain, ice or thunderstorms.

Storage and maintenance

• Store rails, anchors and accessories in a dry, ventilated place protected from the weather; avoid direct contact with damp floors.
• Avoid stacking that could deform profiles or frames; use stable supports and impact protection.
• Separate dissimilar metals during storage to reduce corrosion; keep connectors and terminals capped with dust plugs.
• Protect plastics and rubbers from solar radiation until installation; keep sealants and adhesives in their original packaging and within their shelf life.
• Periodically check (especially after storms) bolt tightness and the condition of anchors, seals and profiles; replace damaged or corroded parts.
• Inspect the cabling: ties, chafe points and insulation; re-route or protect where necessary.
• Clean without abrasive products or pressure jets on seals; remove leaves and debris that obstruct drainage or ventilation.

Restrictions on use

• Do not use the structure as scaffolding, a walkway or a safety anchor point.
• Do not modify, drill or cut components contrary to the manufacturer's instructions; do not reuse deformed or damaged fixings.
• Do not mix connectors or accessories from incompatible makes/models.
• Do not install on deteriorated roofs or structures, those with damp issues, or without sufficient load-bearing capacity.
• Do not exceed the specified loads for wind, snow or impact; observe minimum distances to edges and obstacles where specified.
• Do not carry out electrical connections or live work without the proper qualifications and tools.
• Do not work at height alone, and keep children and pets away from the installation and maintenance area.
• Do not assemble or handle components during adverse weather conditions.
