Asphalt/Bitumen

Signal word

Hazards and Precautions Harmful if swallowed or if inhaled. May be harmful in contact with skin. Contact with hot asphalt will cause thermal burns. Exposure to vapors may cause respiratory tract irritation. Product may contain or release poisonous hydrogen Sulfide gas. Inhalation of vapors or mists may cause central nervous system depression, light-headedness, dizziness, headache, nausea and loss of coordination. May cause eye irritation. Water contact with hot materials can cause violent eruption

Prevention

Do not handle until all safety precautions have been read and understood. 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.

Response

IF exposed or if you feel unwell: Call a POISON CENTER or doctor/physician. If hot asphalt gets on skin, immediately immerse in water for up to 10 minutes. No attempt should be made to remove asphalt from skin in the field. Get medical attention immediately. Physical Form  Liquid (heated) Solid – cooled state Color  Black Odor  Mild Hydrocarbon.
