3. Hazards Identification
Appearance and Odor: Brown/black viscous liquid, with an asphalt odor which may be released upon
heating or burning of product.
Under normal conditions of use, this product is not expected to create any unusual emergency hazards.
NOTE: Hydrogen sulfide (H2S), an extremely toxic gas, may be emitted from heated asphalt and may
accumulate I storage tanks and other confined spaces. At low concentrations, H2S is irritating to the
eyes, nose and throat, and at high concentrations (>500ppm) can cause rapid unconsciousness and
death. The odor of H2S cannot be used as an indicator of exposure, because the gas causes rapid
olfactory fatigue, which deadens the sense of smell. Use this product only under well-ventilated
working conditions.
Skin irritation may be treated by gently washing affected area with soap and warm water.
Flushing eyes with large amounts of water may treat eye irritation. If irritation persists, contact a
physician.
In the event of fire, follow normal fire fighting procedures to prevent inhalation of smoke and gases.

4. First Aid Measures
Inhalation
Move victim to fresh air and call emergency medical care. Apply artificial respiration if victim is not
breathing. Administer oxygen if breathing is difficult.
Skin
If material is hot, cool and allow medical personnel to remove clothing. If material is not hot, remove
and isolate contaminated clothing and shoes at the site. Immediately flush skin with running water for
at least 20 minutes. Wash skin with soap and water.
Absorption
Not applicable
Ingestion
Do not give anything by mouth to an unconscious victim. Do not induce vomiting. Get medical
attention.
Eyes
In case of contact with substance, immediately flush eyes with running water for at least 20 minutes.
Get medical attention.
Section 5. Fire Fighting Measures
Flash Point: min 500癋 Method Used: Cleveland Open Cup
Upper Flammable Limit (UFL): Not determined Lower Flammable Limit (LFL): Not determined
Auto Ignition: Not determined Flammability Classification: Not determined
Rate of Burning: Not determined
General Fire Hazards
There is potential for fire or explosion when heated.
Hazardous Combustion Products
Burning of this material will produce thick, black smoke.
Extinguishing Media
Use water spray, dry chemical, foam, or carbon dioxide. Use water spray or fog; do not use straight streams.
Special Fire Fighting Procedures
Combustible; Avoid breathing fumes. Firefighters should not enter confined spaces without wearing NIOSH
approved positive pressure breathing apparatus (SCBA) with full face mask and full protective equipment. Use
water to keep fire-exposed containers cool.
Unusual Fire or Explosion Hazards
Will be easily ignited by heat, sparks or flames. Vapors may form explosive mixtures with air. Vapors may
travel to a source of ignition and flash back. Vapors are heavier than air and will spread along ground and
collect in low or confined areas (sewers, basements, tanks). Vapor explosion hazard indoors, outdoors or in
sewers. Runoff to sewer may create fire or explosion hazard. Containers may explode when heated. Liquid is
lighter than water. May be transported hot.
Section 6. Accidental Release Measures
Containment Procedures and Clean-Up Procedures
Eliminate all ignition sources (no smoking, flares, sparks or flames in immediate area). All equipment used
when handling the product must be grounded. Do not touch or walk through spilled material. Stop leak if you
can do it without risk. Prevent entry into waterways, sewers, basements or confined areas. A vapor suppressing
foam may be used to reduce vapors. Absorb or cover with dry earth, sand or other noncombustible material and
transfer to containers. Use clean non-sparking tools to collect absorbed material. For large spills, dike far ahead
of liquid spill for later disposal. Water spray may reduce vapor; but may not prevent ignition in closed spaces.
Wastes are not hazardous as defined by the Resource Conservation and recovery Act (RCRA; 40CFR261).
Comply with state and local regulations for disposal of these products. If you are unsure of the regulations,
contact your local Public Health Department, or the local office of the Environmental Protection Agency (EPA).

Section 8. Exposure Controls/Personal Protection
Personal Protective Equipment
Eyes/Face: Safety glasses with side shields are recommended.
Skin: Nitrile, Neoprene
Respiratory: Normally not needed in well-ventilated areas. If applicable standards are exceeded or are
likely to be exceeded, use a NIOSH/MSHA approved, contaminant-specific, air-purifying respirator. If such
concentrations are sufficiently high so that a respirator is inadequate, or high enough to cause oxygen
deficiency, use a positive pressure self-contained breathing apparatus (SCBA). Follow all applicable respirator
use, fitting, and training standards and regulations.
Ventilation: Recommended. Use explosion-proof type.

Section 10. Chemical Stability and Reactivity Information
Chemical Stability
This is a stable material
Incompatibility
A very dangerous fire and explosion hazard when exposed to heat or flame; can react vigorously with oxidizing
materials.
Hazardous Decomposition
Burning can produce carbon monoxide and carbon dioxide. Carbon monoxide is highly toxic if inhaled
(200ppm OSHA Ceiling). Carbon dioxide in sufficient quantities can act as an asphyxiate. When heated to
decomposition it emits smoke and irritating acrid fumes.
Hazardous Polymerization
Will not occur.

International Agency for Research on Cancer, and/or the Occupational Safety and Health Administration:
Component Carcinogenicity
Asphalt ?Suspected carcinogen with experimental carcinogenic and tumorigenic data. A moderate irritant.
