SECTION 2: Hazards identification

NOTICE Bitumen membrane laminated on asphaltic panel, rockwool panel or polyisocyanurate panel. Asphalt odour. Under normal use, this product is not expected to create any health or environmental hazard. Inhalation of dust or fumes from asphalt, rockwool or polyisocyanurate can cause a respiratory irritation and/or congestion.

The exposure to the product above the limits of exposure is not likely to occur considering its form (incorporated in the mixture) and the provided use. The limit of exposure is given for reference only. 2. A proportion of crystalline silica can be present in the sand sprinkled on the top of some membranes. The crystalline silica contained in the sand is not likely to be found in the ambient air in concentration above the limit of exposure since the sand adheres to the surface of the membrane. 3. Pentane and isopentane can be released at very low concentrations (well below the lower flammability limit) of these products when they are cut or crushed. These pentanes are not toxic at concentrations below their lower flammable limit.
