Main risks

• Trips and falls due to misaligned, loose or protruding gratings.
• Cuts or pinching injuries when handling gratings, sharp edges or damaged parts.
• Entrapment of footwear, wheels or fingers in unsuitable openings or open gratings.
• Breakage due to overloading if heavier vehicles than intended pass over, with a risk of collapse.
• Strain injuries when lifting heavy covers or gratings without the proper tool.
• Blockages causing overflows and local flooding.
• Standing water that encourages bad odours, algae, mosquitoes and slippery surfaces.
• Damage to buried services (cables, pipes) during excavation or installation.
• Frost and ice that can crack parts and make the area slippery.

Safe use

• Before digging, check for the possible presence of pipes and cables using plans or detectors.
• Wear sturdy gloves and eye protection when cutting, installing, opening or cleaning.
• Install the channels on a firm, level base; leave the gratings flush with the paving.
• Secure the gratings with their fixings; do not leave unprotected openings or poorly seated covers.
• Select the product according to the intended use (pedestrian, bicycle, light vehicle traffic); do not drive over or load it if it is not designed for that.
• Periodically remove leaves, mud and sediment; use the appropriate tool to lift the grating, never your fingers.
• Avoid pouring grease, paints, cement, solvents or wipes that could block or damage the materials.
• When cleaning with a pressure washer, keep a safe distance so as not to damage joints or coatings.
• After heavy rain, check that water drains correctly and that there are no displacements or settlement.

Storage and maintenance

• Store components in a dry, ventilated place protected from direct sunlight and frost, especially plastic parts and seals.
• Avoid impacts and twisting; stack flat without placing excessive weight on gratings or channels.
• Keep screws, clips and accessories together and labelled to prevent loss.
• Inspect after storms or heavy use: check the integrity of frames, fixings and gratings; replace cracked, deformed or corroded parts.
• Clean channels with water and a soft brush; avoid aggressive chemicals that could damage plastics, rubbers or galvanised finishes.
• Periodically check joints and seals; renew deteriorated seals to prevent leaks into the ground.
• If the system includes a trap or odour seal, maintain the water level to reduce odours and the ingress of pests.
• In winter, remove ice without sharp tools; the use of salts may accelerate corrosion of metal components.
• Compact and level the surroundings if settlement occurs to avoid protruding edges.

Restrictions on use

• Do not use gullies and channels to discharge high-temperature liquids, oils, fuels, solvents, acids or alkalis.
• Do not use gratings as a step, support, anchorage point or working platform.
• Do not modify, cut or drill parts in a way that affects their strength or fit; use only compatible accessories.
• Do not install in areas of heavy traffic or machinery if the product is not intended for that load.
• Do not cover gratings with soil, mats or other materials that prevent water entry.
• Do not use improvised tools to lift heavy covers; use suitable lifting keys or hooks.
• Keep children and pets away during installation, cleaning or when gratings are open.
• Installations on steep slopes, in vehicle traffic areas or next to buried service connections may require qualified personnel.
