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.
