Other Component Information
‐
IARC has concluded that the following chemicals in this product are carcinogenic to humans
(Group 1): silica, quartz. ACGIH has designated the following chemicals in this product as
suspected human carcinogens (A2): silica, quartz. NTP has listed the following chemicals in this
product as known human carcinogens: silica, quartz. Risk of cancer depends on duration and
level of exposure to this product as a dust or aerosol mist.
Other Information
‐
This product contains petroleum asphalt. Petroleum asphalt is not listed as a carcinogen by
OSHA or NTP. The National Institute of Occupational Safety and Health (NIOSH), has
concluded that at higher temperatures roofing asphalt fumes are a potential occupational
carcinogen. If this product is heated or comes in contact with heated material, avoid breathing
fumes. This product may contain small amounts of polycyclic aromatic hydrocarbons (PAH’s)
which are recognized carcinogens in humans and experimental animals. Mouse skin painting
studies of roofing asphalt vapor concentrate have shown evidence of tumor formation
associated with localized skin irritation in recent studies. Inhalation studies of high airborne
concentrations of asphalt/bitumen fumes in rats and mice produced bronchitis, pneumonitis, and
lung changes such as fibrosis and cell damage.
