Asphalt Emulsion SS-1h

SECTION 2: Hazards identification

EMERGENCY OVERVIEW WARNING Do not let wet material contact skin or eyes. Contact with product can cause severe chemical burns to eyes and skin. Fumes, mists or vapors may cause eye, skin or respiratory irritation.

Potential health effects

Note: This product may be hot (approximately 140 - 170°F), and is alkaline (pH approximately 10-11). Therefore, contact with eyes and skin should be avoided. Significant airborne emissions (fumes, mists, vapors) from this product are considered unlikely under normal use and working conditions. Inhalation: Emissions from the heated material may have an unpleasant odor and may cause moderate to severe irritation of the mucous membranes and upper respiratory tract, headaches, nausea and dizziness. Toxic hydrogen sulfide gas may be released. Do not depend upon sense of smell for warning of overexposure, since the gas causes rapid olfactory fatigue which deadens the sense of smell at levels as low as 50 ppm. Unconsciousness and asphyxiation may occur in poorly ventilated or confined spaces. See Section 11 for additional information. Ingestion: May cause alkali burns. Direct contact with heated material can cause severe thermal burns. Asphalt has a low toxicity when ingested, however, chewing and swallowing asphalt may cause gastrointestinal effects. Gastric masses (Bezoars) and stomach (pyloric) obstructions have been reported in individuals who have chewed and swallowed asphalt. Aspiration of product into lungs may occur when vomiting, and may result in pulmonary edema and/or chemical pneumonia. Effects Following Prolonged or Repeated Exposure: Prolonged and repeated exposure may cause skin disorders and/or effects on the lung. See Section 11 for additional information. Carcinogenicity: The following components of this product have been listed as carcinogens by the International Agency for Research on Cancer (IARC), the National Toxicology Program (NTP), or the Occupational Safety and Health Administration (OSHA): some petroleum asphalts and heavy naphthenic distillates/aromatic extract oils. See Section 11 for additional information. Signs and Symptoms of Exposure: Repeated or prolonged exposure may cause skin disorders such as dermatitis (reddening, itching, cracking, inflammation), folliculitis, acne-like lesions, bronchitis, pneumonitis (inflammation of the lungs), reduced appetite, abnormal fatigue.

Principle Routes of Exposure

Eyes, skin, inhalation. Eye Contact: May produce severe irritation and/or chemical (alkali) burns. Symptoms may include tearing, redness or a stinging sensation. May cause swelling of the eyes with blurred vision. Can injure eye tissue. Effects may become more serious with repeated or prolonged contact. Direct contact with hot material can cause severe thermal burns. Fumes, vapors or mists may be irritating. Skin Contact: May produce irritation and/or chemical (alkali) burns. Symptoms may include redness, an itching or burning sensation, and/or swelling of the skin. May cause skin damage. Direct contact with hot material can cause severe thermal burns. There may be an increased sensitivity to the sun (photosensitization) when the skin is exposed to petroleum asphalt emissions (fumes, vapors or mists). May scratch the skin causing irritation. See Section 11 for additional information. Skin Absorption: Not expected to be a significant exposure route following short-term exposure. Repeated or prolonged exposure may result in absorption of component petroleum distillates. See Section 11 for additional information. 05/01/2012 MSDS 3239-063

Medical Conditions Generally Aggravated by Exposure

Pre-existing medical conditions that may be aggravated by exposure include disorders of the eye, skin and/or lung (including asthma and/or other breathing disorders).
