4. FIRST AID MEASURES
Inhalation: If affected, move person to fresh air. If breathing is difficult, administer oxygen. If not
breathing or if no heartbeat, give artificial respiration or cardiopulmonary
resuscitation (CPR). Immediately call a physician. If symptoms or irritation occur with
any exposure, call a physician.
Skin contact: For contact with hot molten material, immerse or flush skin with cold water for at least
15 minutes. Call a physician. Do not attempt to remove solidified material since
removal may cause further tissue injury. Cold material over a burn should not be
removed except by a physician. Remove cold material (not associated with a burn)
with waterless handcleaner and then wash with soap and water. If symptoms or
irritation occur, call a physician.
Ingestion: Ingestion not likely. If large amounts are swallowed, immediately call a physician.
Eye contact: For contact with hot molten material, flush with large amounts of tepid water for at
least 15 minutes. Immediately call a physician.
For contact with vapors or dust, flush with large amounts of tepid water for at least 15
minutes. If symptoms or irritation occur, call a physician.
Notes to physician: Recommended practice is to not attempt to remove hot material associated with a
burn. Allow the solidified material to remain in place until cooled so it can naturally
fall off. Natural separation will occur in 48-72 hours. If removal is attempted, mineral
oil may be used to remove asphalt once it is cooled. For best results, work it into the
skin around the material and allow the material to "float" off.
Medical conditions aggravated by Preexisting skin, eye and respiratory disorders may be aggravated by exposure to
exposure: components of this product.
5. FIRE FIGHTING MEASURES
Suitable extinguishing media: For small fires, Class B fire extinguishing media such as
CO2, dry chemical, foam (AFFF/ATC) or water spray can be
used. For large fires, water spray, fog or foam (AFFT/ATC)
can be used. Fire fighting should be attempted only by those
who are adequately trained and equipped with proper
protective equipment.
Specific hazards: This product is not a combustible liquid per the OSHA
Hazard Communication Standard, but will ignite and burn at
temperatures exceeding the flash point.
Special protective equipment for firefighters: Avoid using straight water streams. Water spray and foam
(AFFF/ATC) must be applied carefully to avoid frothing and
from as far a distance as possible. Avoid excessive water
spray application. Keep run-off water out of sewers and
water sources.

6. ACCIDENTAL RELEASE MEASURES
Personal precautions: Keep public away. Isolate and evacuate area. Shut off source if safe to do so.
Advise authorities and National Response Center (800-424-8802) if substance has
entered a watercourse or sewer. Notify local health and pollution control agencies, if
appropriate. Contain liquid with sand or soil. Recover and return product to source.
7. HANDLING AND STORAGE
Handling:
Comply with all applicable EPA, OSHA, NFPA and consistent state and local requirements. Use appropriate grounding
and bonding practices. Store in properly closed containers that are appropriately labeled and in a cool well-ventilated
area. Do not expose to heat, open flames, strong oxidizers or other sources of ignition. Do not cut, drill, grind or weld on
empty containers since they may contain explosive residues.
Significant concentrations of hydrogen sulfide (H2S) gas can be generated and accumulate in storage tanks and bulk
transport compartments which may require additional precautions and procedures during loading/unloading. When
opening covers and outlet caps on storage tanks, use face shield and gloves to avoid possible injury from pressurized
product. Stay upwind and vent open hatches before unloading. Keep heating coils and flues in storage tanks, trucks and
kettles covered with product (8"). Do not overheat.
Avoid skin contact. Exercise good personal hygiene including removal of soiled clothing and prompt washing with soap
and water.
8. EXPOSURE CONTROLS / PERSONAL PROTECTION
PERSONAL PROTECTIVE EQUIPMENT
Engineering measures: Local or general exhaust required in an enclosed area or when there is inadequate
ventilation.
Respiratory protection: Not required under normal conditions and adequate ventilation. When H2S vapors
exceed permissible limits, i.e., in confined spaces or bulk transport
loading/unloading, a positive-pressure atmosphere supplying respirator is
recommended. Self-contained breathing apparatus should be used for fire fighting.
Skin and body protection: Insulated gloves when handling hot material.
Eye protection: Goggles and faceshield when handling hot material.
Hygiene measures: Rubberized suits or coats may be needed for some maintenance operations with hot

Some epidemiologic studies conducted on workers exposed to asphalt fume have shown no increased incidence of
cancer while other studies have reported a slightly increased incidence of lung, other respiratory tract or gastrointestinal
cancers. In those studies in which elevated cancer incidences were reported, concurrent or previous exposure to coal-tar
products have been documented. therefore, it cannot be concluded that cancer incidence is related to exposure to
asphalt fume.
Although early studies have some technical shortcomings, long term inhalation exposures to asphalt aerosols or fumes
did not produce evidence of carcinogenicity even though chronic inflammatory changes similar to those produced by
nonspecific respiratory irritants were observed. Inhalation of 150 mg/m3 asphalt fume (particulate + vapor) 6 hours/day, 5
days/week for 13 weeks, did not produce toxicity except for reduced body weight and irritation in nasal passages in
exposed rats.
Laboratory animals administered subcutaneous or intramuscular injections of asphalt preparations or repeated skin
applications of hot (212 F) undiluted asphalt have occasionally produced a low incidence of skin tumors at the site of
application. These findings are of questionable validity since repeated tissue trauma (and/or burns) at the application site
can induce tumors. Solvent dilutions of different types of asphalts have been tested in chronic skin painting studies. Some
of the studies have reported a low incidence of skin tumors. The use of diluents may enhance bioavailability or metabolic
activation of chemicals in the mixture in a fashion not representative of occupational exposure. Skin painting studies in
mice have been conducted using condensates from fumes generated at temperatures >450 F diluted in solvent. Asphalt
fume condensate preparations have produced skin tumors. Experimental conditions (temperature and dose) were grossly
exaggerated over that likely to occur in humans.
Extracts of whole asphalts tested in a modified Ames assay gave negative or slightly positive findings (mutagenicity index
<1.5). Fume condensates derived from heating asphalts to high temperatures (>450 F) were moderately active (MI 4-9).
Fumes generated from coal tar pitch were >1000 times more active. Asphalt fume samples collected under actual field
conditions did not show any significant mutagenic activity.
Summary of health effect data on asphalt components:
This product can contain a toxicologically significant concentration of hydrogen sulfide (H2S). Hydrogen sulfide gas (H2S)
is toxic by inhalation. Prolonged breathing of 50-100 ppm H2S vapors can produce eye and respiratory tract irritation.
Higher concentrations (250-600 ppm) for 15-30 minutes can produce headache, dizziness, nervousness, nausea and
pulmonary edema or bronchial pneumonia. Concentrations of >1000 ppm will cause immediate unconsciousness and
death through respiratory paralysis. Rats and mice exposed to 80 ppm H2S, 6 hrs/day, 5 days/week for 10 weeks, did not
produce any toxicity except for irritation of nasal passages. H2S did not affect reproduction and development (birth
defects or neurotoxicity) in rats exposed to concentrations of 75-80 ppm or 150 ppm H2S, respectively. Over the years a
number of acute cases of H2S poisonings have been reported. Complete and rapid recovery is the general rule.
However, if the exposure was sufficiently intense and sustained causing cerebral hypoxia (lack of oxygen to the brain),
neurologic effects such as amnesia, intention tremors or brain damage are possible.

Additional Information: The pronounced and easily-recognized rotten egg odor of hydrogen sulfide gas
(H2S) can be detected at concentrations as low as 0.003-0.13 ppm. Since higher
H2S concentrations (100-200 ppm) cause olfactory fatigue and other hydrocarbon
odors can "mask" H2S, the sense of smell cannot be used as a reliable indicator of
H2S exposure.
