SECTION 2: Hazards identification

Emergency Overview NFPA WARNING Contact With Hot Product Will Cause Thermal Burns May contain or release poisonous hydrogen sulfide gas Appearance: Black, viscous Physical Form: Semi-Solid Odor: Asphalt

Potential health effects

Eye: Not expected to be an eye irritant. Contact with the heated material may cause thermal burns. Vapors or fumes may cause watering of the eyes. Skin: Contact with the heated material may cause thermal burns. Fumes from the heated material can cause irritation and dermatitis after prolonged or repeated exposure. Long term skin exposure can increase sensitivity to the sun and cause discoloration of the skin. No harmful effects from skin absorption have been reported. Inhalation (Breathing): No information available on acute toxicity. May contain or release poisonous hydrogen sulfide gas - see Other Comments. Ingestion (Swallowing): No harmful effects reported from ingestion. Signs and Symptoms: Ingestion may cause irritation of the digestive tract, nausea, vomiting, and diarrhea. Breathing vapors or fumes from the heated material may cause headaches, dizziness, and lung irritation. Repeated exposure to high concentrations of fumes may cause chronic bronchitis and pneumonitis (inflammation of the lungs). Other Comments: This material may contain or liberate hydrogen sulfide, a poisonous gas with the smell of rotten eggs. The smell disappears rapidly because of olfactory fatigue so odor may not be a reliable indicator of exposure. Effects of overexposure include irritation of the eyes, nose, throat and respiratory tract, blurred vision, photophobia (sensitivity to light), and pulmonary edema (fluid accumulation in the lungs). Severe exposures can result in nausea, vomiting, muscle weakness or cramps, headache, disorientation and other signs of nervous system depression, irregular heartbeats, convulsions, respiratory failure, and death. This material may contain varying concentrations of polycyclic aromatic hydrocarbons (PAHs) which have been known to produce a phototoxic reaction when contaminated skin is exposed to sunlight. The effect is similar in appearance to an exaggerated sunburn, and is temporary in duration if exposure is discontinued. Continued exposure to sunlight can result in more serious skin problems including pigmentation (discoloration), skin eruptions (pimples), and possible skin cancers. See Section 11 for additional Toxicity Information.
