SECTION 2: Hazards identification

EMERGENCY OVERVIEW Semi-rigid protection board composed of a mineral fortified asphaltic core formed between two saturated fibreglass felts. Presents an asphalt odour Under normal use, this product is not expected to create any health or environmental hazard. Inhalation of dust or of asphalt fumes can cause a respiratory irritation. SECTION III: COMPOSITION AND INFORMATION ON HAZARDOUS INGREDIENTS NAME CAS # % WEIGHT EXPOSURE LIMIT (ACGIH) TLV-TWA TLV-STEL Oxidized Asphalt 64742-93-4 60-65 0.5 mg/m³ Not established 1 f/cc for fibres longer than 5 µm Fibreglass 65997-17-3 7-13 Not established with a diameter less than 3 µm Effects of Short-Term (Acute) Exposure Effects of Long-Term (Chronic) Exposure INHALATION SKIN CONTACT No possible health effect if the product is not heated. Oxidized Asphalt: No likely health effect if the product is not heated. Exposure to asphalt fumes may cause a severe irritation to the skin and Oxidized Asphalt: Inhalation is possible only if the product is heated or may cause dermatitis and lesions similar to acne. Long-term contact if asphalt fumes are generated. Asphalt fumes can be irritating for the may cause a change with skin pigmentation which can be worsened by nose, the throat and the upper respiratory tract causing cough, wheezing the exposure to the sun. (1) breath and/or shortness of breath. The acute effects of the exposure to the asphalt fumes include headache, tiredness and decreased appetite. INHALATION Hydrogen sulphide (H2S) can result from excessive heating, agitation Oxidized Asphalt: No likely health effect if the product is not heated. or contact with acids or acid salts. Inhaled H2S can cause a central Prolonged exposure to asphalt fumes may cause irritation to respiratory nervous system depression having for result headache, dizziness, tract. Inhalation of asphalt fumes may cause central nervous system nausea, unconsciousness, and death. (1) depression having for result headache, dizziness, nausea, unconsciousness, and death. (1) Fibreglass: Fibreglass dust may cause mouth, nose and throat irritation. (1) Fibreglass: No chronic effect on health is known to be associated with exposure to fibreglass of continuous filament. (1) SKIN CONTACT Frequent or prolonged contacts may cause skin irritation. NERVOUS SYSTEM EFFECTS No information available. Oxidized Asphalt: No likely health effect if the product is not heated. Exposure to asphalt fumes may cause a severe irritation to skin and CARCINOGENICITY may cause dermatitis and lesions similar to acne. The contact with the Oxidized Asphalt: In its 2013 monograph (Volume 103), the hot product can cause serious burns. (1) International Agency for Research on Cancer (IARC) conducted a Fibreglass: Fibreglass dust may cause skin irritation. (1) review of the potential carcinogenicity of bitumen (the European term for asphalt). One of its conclusions was "occupational exposures to EYE CONTACT oxidized bitumens and their emissions during roofing" are classified in Oxidized Asphalt: No likely health effect if the product is not heated. IARC Group 2A, "probably carcinogenic to humans.". However, due to The fumes may cause irritation and redness. The contact with the hot the product form, exposure to such component is unlikely under normal product can cause serious burns. (1) conditions of use. (1) Fibreglass: Particles or dust of the product may cause irritations. (1) Fibreglass: The epidemiological results of studies have not shown any INGESTION increase in respiratory disease or cancer. IARC classified fibreglass in It is unlikely that toxic quantities of the product are ingested under continuous filament “Not classifiable as carcinogen to humans” normal use and handling of the product.
