Section 2: Hazardous Ingredients

Chemical Names CAS Number Quantity (Percent) Formula Exposure Limits in Air
ACGIH TLV1 OSHA PEL2
Petroleum distillate 8052-42-4 < 5 various 100 ppm none
Hydrogen sulfide 7783-06-4 < 1 H2S 10 ppm 20 ppm
  1. ACGIH TLV: American Conference of Industrial Hygienist Threshold Limit Value (TLV) time-weighted average (TWA)
  2. OSHA PEL: Occupational Safety and Health Association Permissible Exposure Limit for an 8-hour time weighted average

Section 3: Hazard Identification

  • Route of Entry:
    • Inhalation: Yes
    • Skin: Yes
    • Ingestion: No
  • Acute and Chronic Effects: Heated material may cause thermal burns or rash. When cold, no effects expected. Single short-term exposures can cause skin irritation on prolonged or repeated exposure. Inhalation: Vapors containing hydrogen sulfide that may accumulate during storage or transport.
  • Carcinogenicity: NTP, IARC, OSHA: none reported.
  • Signs/symptoms of Overexposure: Irritation to eyes, skin and lungs after repeated exposure. Eyes/skin: Permanent damage, rash, thermal burns.

Section 4: First Aid Measures

  • Eye contact: Immediately flush with plenty of water for at least 15 minutes. Get immediate medical attention.
  • Skin contact: Immediately flush with cool water for at least 15 minutes. Clean skin with waterless hand cleaner. Seek medical aid if irritation persists or develops.
  • Inhalation: Remove from exposure. Seek medical aid if respiratory difficulty persists or develops.
  • Ingestion: Seek medical aid. Do not induce vomiting.

Section 5: Fire And Explosion

  • Flash point: 200°F
  • Flash point method: COC
  • Extinguishing media: Agents approved for Class B fires (e.g., CO2, dry chemical, or foam, water fog).
  • Special Fire Fighting Procedures: Use NIOSH/MSHA approved SCBA and full protective equipment.
  • Unusual Fire & Explosion Hazard: If hydrogen sulfide is present in sufficient quantities, flammable limits can increase to 4–45% by volume and pyrophoric iron compounds can be formed.

Section 6: Accidental Release Measures

  • Spill Response Procedures: Recover spilled material and reuse.
  • Preparing Waste for Disposal: Disposal must be in accordance with applicable federal, state, and local regulations. Enclosed-controlled incineration recommended, depending on jurisdiction.

Section 7: Handling & Storage

  • Respiratory Protection: None needed at ambient temperatures. If present in high vapors concentrations or TLV is exceeded, use NIOSH/MSHA approved supplied-air respirator.
  • Eye Protection: Safety glasses with side shields should be worn at all times.
  • Gloves: Nitrobutyl rubber or neoprene.
  • Other Clothing: Long sleeves.
  • Work Practices: Do not smoke.
  • Hygiene Practices: Wash exposed skin with soap and water.
  • Other Handling Requirements: No special measures required.
  • Protective Measures During Maintenance of Contaminated Equipment: No special measures required
  • Storage: Keep adequate ventilation in outside storage. Hydrogen sulfide gas may accumulate in storage tanks and bulk transport compartments containing asphalts.

Section 8: Physical Properties

  • Vapor density (air=1): Negligible
  • Melting point: N/A
  • Specific gravity: 1.0–1.9
  • Boiling point: N/A
  • Solubility in water: Negligible, < 0.1%
  • Evaporation rate: Negligible
  • Vapor pressure: N/A
  • Appearance and odor: Black semi-solid mixture

Section 9: Stability and Reactivity

  • Reactivity: Material is stable and will not polymerize. May react with strong oxidizing agents such as chlorates, nitrates and peroxides. At room temperature, hydrogen sulfide may be given off.
  • Materials & Conditions to Avoid: High temperature heating.
  • Hazardous Decomposition Products: Heating this material may produce hydrogen sulfide.

Section 10: Toxicological Information

The International Agency for Research on Cancer (IARC) conducted a thorough literature search in 1985 and determined that there is inadequate evidence for the carcinogenicity of undiluted asphalt (the major ingredient in emulsified asphalt) in animals and humans.
