Main risks

• Burns from using a blowtorch and from contact with hot bitumen.
• Fire when applying heat near combustible materials, electrical or gas installations.
• Inhalation of bitumen fumes and vapours from primers or adhesives in poorly ventilated spaces.
• Cuts from utility knives, scissors and cutting tools.
• Falls and slips on roofs, especially with moisture, dust or debris present.
• Overexertion and entrapment injuries when handling heavy rolls.
• Damage to the substrate from overheating or direct flame.
• Hot particles or sparks projected during overlapping and sealing.
• Loss of watertightness due to application on substrates that are damp, dirty or unstable.

Safe use

• Read and follow the manufacturer's instructions for the membrane type, substrate and installation method.
• Prepare the surface: sound, clean, dry and free of dust; respect the overlaps and direction of installation indicated by the manufacturer.
• Avoid installing in rain, snow, frost or strong winds; plan water drainage and protect junctions, drains and perimeters.
• When using a blowtorch, keep the flame moving, avoid overheating and keep an appropriate extinguisher to hand; protect combustible elements with heat shields.
• Ensure sufficient ventilation when using heat, primers or adhesives; do not smoke or introduce flames or sparks.
• Check the condition of the gas equipment (hoses, regulator, connections) and place the cylinder upright and stable, away from sources of heat.
• Use personal protective equipment: heat- and cut-resistant gloves, goggles, long-sleeved clothing and slip-resistant footwear; at height, helmet, harness and lifeline.
• Make cuts on a stable base, with sharp blades and hands kept clear of the cutting path; retract or guard the blade when finished.
• Do not step on or load weight onto the freshly applied membrane; allow it to cool and set before walking on it.
• Keep the work area tidy, remove debris and mark off perimeters and openings on the roof.

Storage and maintenance

• Store rolls vertically, in a dry, ventilated place, protected from the weather, direct sunlight and sources of heat or ignition.
• Avoid crushing and deformation: do not overstack or place heavy loads on the rolls.
• Keep primers and adhesives tightly closed, away from sparks or flames; follow the manufacturer's temperature recommendations.
• Transport the rolls with appropriate handling aids to avoid overexertion; do not let them roll on the roof.
• After installation, keep gutters, drains and perimeters clean; remove leaves and debris that may obstruct drainage.
• Inspect the waterproofing periodically to detect punctures, cracks or delamination and repair them according to the manufacturer's instructions.
• Avoid harsh cleaning products or incompatible solvents; do not pierce the membrane to fix elements without appropriate sealing.
• If occasional traffic is expected, use walkways or suitable protection to avoid damaging the surface.

Restrictions on use

• Do not expose the membrane to permanent UV radiation unless the product is designed to remain exposed.
• Do not apply on substrates that are damp, frozen, friable or with loose dust.
• Do not use flame or solvents in enclosed spaces without adequate ventilation.
• Do not use near heat-sensitive materials without suitable barriers or protection.
• Do not use as a surface for intensive foot traffic or wheeled traffic unless systems specifically designed for this are used.
• Do not combine with adhesives, primers or coatings not specified by the manufacturer.
• Do not install near chimneys, braziers or heat sources without the appropriate flashings and protections.
• Keep the product and tools out of the reach of children and pets.
• Work at height and the use of a blowtorch must be carried out by trained persons and, where appropriate, under competent supervision.
