Not pertinent; Boiling Point at I atm.: Not pertinent; Freezing Point: Not pertinent; Critical
Temperature: Not pertinent; Critical Pressure: Not pertinent; Specijic Gravity: 1.00 at 20°C (liquid);
Vqor (Gas) Density: Not pertinent; Ratio ofSpecijic Heats of Vqor (Gas): Not pertinent; Latent Heat
of Vqorization: Not pertinent; Heat of Combustion: Data not available; Heat of Decomposition: Not
pertinent.
Health Hazards Information -Recommended PersonalProtective Equipment: Protective clothing; face
and eye protection when handling hot material; Symptoms Following Exposure: Contact with skin may
cause dermatitis. Inhalation of vapors may cause moderate irritation of nose and throat. Hot liquid
burns skin; General Treatment for Exposure: Severe burns may result from contact with hot asphalt.
If molten asphalt strikes the exposed skin, coll the skin immediately by quenching with cold water. A
burn should be covered with a sterile dressing, and the patient should be taken immediately to a
hospital; Toxicity by Inhalalion (Threshold Limit Value): 5 mg/m3; Short-Tern Enposure Limits: Data
not available; Toxiciv by Ingestion: Grade 1; LD, 5 to 15 glkg; Late Toxicity: None observed; Vapor
(Gas) Irritant Characteristics: Vapors cause a slight smarting of the eyes or respiratory system if
present in high concentrations. The effect is temporary; Liquid or Solid Zm'tant Characteristics: Causes
smarting of the skin and fmt-degree burns on short exposure; may cause secondary burns on long
exposure; Odor Threshold Data not available.
Fire Hazards -Flash Point (deg. F): 300 - 350 OC; Flammable Limits in Air (9%): Not pertinent; Fire
Extinguishing Agents: Water spray, dry chemical, foam or carbon dioxide; Fire Extinguishing Agents
Not To Be Used Water or foam may cause foaming; Special Hazards of Combustion Products: Not
pertinent; Behavior in Fire: Not pertinent; Ignition Temperature (deg. F): 400 - 700; Electrical Hazard
Not pertinent; Burning Rate: No data.
Chemical Reactivity - Reactivity with Water: No reaction; Reactivity with Common Materials: No
reactions; Stability During Transport: Stable; Neutralizing Agents forAcids and Caustics: Not pertinent;
Polymerization: Not pertinent; Inhibitor of Polymerization: Not pertinent.

Health Hazards Information -Recommended Personal Protective Equipment: Dust mask, goggles and
rubber gloves; Symptoms Following Exposure: Irritation of eyes and skin. If ingested, irritates mouth
and stomach.; General Treatment for Exposure: EYES - Flush with copious amounts of water for at
least 15 to 20 minutes. SKIN - Wash with large amounts of water. INGESTION - Induce vomiting and
give saline laxative and supportive therapy; Toxicity by Inhalation (Threshold Limit Value): No data;
Short-Tern Exposure Limits: No data; Toxicity by Ingestion: Oral rat LD,, = 3080 mg/kg; Late
Toxicity: No data; Vapor (Gas) Irritant Characteristics: Vapors are nonirritating to eyes and throat.;
Liquid or Solid Zrritunt Characteristics: Causes smarting of the skin and first-degree chemical burns
on short exposure and may cause second-degree burns on long exposure; Odor Threshold No data.
