SECTION 2: Hazards identification

Fire retardant wood fibre board with a base sheet on the top surface. 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 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. Effects of Short-Term (Acute) Exposure information about the chronic effects of exposure to asphalt fumes on the lungs. SKIN CONTACT This product may cause skin irritation because of its rough surface. NERVOUS SYSTEM EFFECTS No information available. Asphalt: If the membrane is torch-applied, the contact with hot product can cause burns.

Asphalt fumes contain substances as benzo (a) pyrene and INHALATION dibenz (a,h) anthracene known as carcinogen to humans (IARC). (1) If the membrane is torch-applied, asphalt fumes can be inhaled. Oxidized asphalt: In October 2011, the IARC conducted a review of the Asphalt: Asphalt fumes can be irritating for the nose, the throat and the potential carcinogenicity of bitumen (the European term for asphalt). One respiratory tract. Inhalation of high concentrations of asphalt fumes can of its conclusions was "occupational exposures to oxidized bitumens and cause a central nervous system depression causing headaches, dizziness, their emissions during roofing" are classified in IARC Group 2A, nausea and unconsciousness. "probably carcinogenic to humans". (1) INGESTION Fibreglass: Fibreglass is not expected to be released. In October 2001, Exposure is not expected by this route of entry under normal product use. IARC classified fibreglass as Group 3 “not classifiable as to its carcinogenicity to humans”. The 2001 decision was based on current Effects of Long-Term (Chronic) Exposure human and animal research that shows no association between inhalation SKIN CONTACT exposure to dust from fibreglass wool and the development of respiratory Repeated or prolonged contact may cause irritation. (1) disease. This is a reversal of the IARC finding in 1987 of a Group 2B INHALATION designation (possibly carcinogenic to humans) based on earlier studies in which animals were injected with large quantities of fibreglass. NTP and If the membrane is torch-applied, asphalt fumes can be inhaled. Long- term exposure to asphalt fumes may cause a change with skin ACGIH have not yet reviewed the IARC reclassification or the most pigmentation which can be worsened by the exposure to the sun. No current fibreglass health research. At this time, both agencies continue to classify glass wool based on the earlier animal injection studies.
