3. HAZARD IDENTIFICATION
EMERGENCY OVERVIEW: This product is a hot, black, viscous, semi-solid with a strong petroleum odor. The primary
hazards associated with this product are irritation of contaminated skin and eyes and burns from contact with the heated
material. Asphalt fumes (and other trace components of this product) are potentially carcinogenic to humans. Toxic
Hydrogen Sulfide may be evolved and can accumulate in the head-space of containers (e.g. tanks, trucks) containing
this product, especially when heated. Presence of Hydrogen Sulfide may result in exposure that can cause severe
irritation of the respiratory system, eyes, and skin and can cause central nervous system effects such as nausea, dizziness,
headaches, and collapse. Thermal decomposition of this product can also produce other irritating vapors and toxic gases
(e.g., carbon oxides, nitrogen oxides, sulfur oxides). This product may ignite if strongly heated. A fire involving this
product may produce heavy, black smoke and toxic gases (including carbon monoxide, carbon dioxide, and
hydrocarbons). This product is not reactive. Emergency responders must wear proper personal protective equipment for
the releases to which they are responding and have adequate fire protection during emergency response situations.
SYMPTOMS OF OVEREXPOSURE BY ROUTE OF EXPOSURE: The primary routes of overexposure for this material
are via inhalation and contact with skin and eyes. The following paragraphs describe the symptoms of overexposure to
this material.
INHALATION: Inhalation of excessive amounts of vapors from hot Asphalt can cause respiratory difficulty, shortness of
breath, wheezing, headache, dizziness, indigestion, and nausea. Inhalation of high concentration of vapors may result in
unconsciousness or death. Chronic over-exposures to the vapors can cause respiratory system irritation, resulting in
symptoms such as coughing and wheezing, which may take a prolonged time to disappear after the over-exposure has
ended. In addition, Fumes of Asphalt are suspected to be carcinogenic if exposure is chronic. Due to the possible off-
gassing of Hydrogen Sulfide, inhalation of fumes from Asphalt may result in Hydrogen Sulfide poisoning. A summary of
possible effects from various levels of Hydrogen Sulfide exposure are outlined on the following page.

also cause persistent low blood pressure. For Routine Industrial Use and Handling Applications
CONTACT WITH SKIN or EYES: If hot Asphalt contaminates the
See Section 16 for Definition of Ratings
eyes, pain, irritation, and tissue damage could occur. Blindness
may result if eyes are contaminated with hot Asphalt. If eye
exposure occurs to low levels of off-gassed Hydrogen Sulfide, exposure over several hours may result in "gas eyes" or "sore
eyes" with symptoms of scratchiness, irritation, tearing, and burning. Exposure to higher concentrations can result in intense
tearing, blurring of vision, and pain when looking at light. Exposed individuals may see rings around bright lights. Most eye
symptoms disappear when exposure ceases; however, in serious cases, the eye can be permanently damaged. Contact with
the vapors from the heated product can redden and irritate the eyes. If hot Asphalt contaminates the skin, pain, irritation
and tissue damage can result. Such burns can leave scar tissue. Contact with the vapors from the heated material can
cause irritation, reddening, and dryness. Repeated or prolonged exposure to the vapors can cause dermatitis
(inflammation of the skin).
SKIN ABSORPTION: Some studies of asphalt products suggest that prolonged skin contact can cause symptoms
described under "Inhalation".
INGESTION: Though not anticipated to be a significant route of occupational exposure, ingestion of Asphalt can irritate
the tissue of the mouth, throat, and other tissues of the gastro-intestinal system. Symptoms of such over-exposure can
include nausea, vomiting, and diarrhea. Ingestion of the heated material can result in burns to the mouth, throat, and other
tissues.
INJECTION: Accidental injection of this material (via cut or puncture with a contaminated object) will cause pain and
irritation in addition to the wound.
HEALTH EFFECTS OR RISKS FROM EXPOSURE: An Explanation in Lay Terms.
ACUTE: The most likely routes of over-exposure are inhalation and skin contact. Symptoms include respiratory difficulty,
shortness of breath, wheezing, headache, dizziness, indigestion, and nausea. If high concentrations of the vapors from
the heated material are inhaled, unconsciousness or death may result. The vapors can also irritate the skin and eyes.
Skin or eye contact with the heated material can result in burns and permanent damage to the contaminated area.
Ingestion may cause stomach distress, vomiting, and diarrhea.
CHRONIC: Repeated or prolonged exposure to the vapors from the heated material can cause dermatitis (inflammation of
the skin). Chronic over-exposures via inhalation of the vapor can cause respiratory system irritation, resulting in symptoms
such as coughing and wheezing, which may take a prolonged time to disappear after the over-exposures have ended.
Due to possible off-gassing of Hydrogen Sulfide, chronic overexposures may also cause persistent low blood pressure, loss
of sense of smell, or permanent eye damage. Asphalt fumes are possibly carcinogenic to humans; prolonged exposure to
this product may result in a cancer hazard. Some of the trace components of this product are known or suspected
carcinogens and/or reproductive toxins. Refer to Section 11 (Toxicological Information) of this MSDS for additional
information.
TARGET ORGANS: ACUTE: Respiratory system, skin, eyes. CHRONIC: Skin, respiratory system, blood system, central
nervous system, liver, kidneys, nerves of feet and hands.

4. FIRST-AID MEASURES
Victims of chemical exposure must be taken for medical attention. Rescuers should be taken for medical attention, if
necessary. Take a copy of label and MSDS to physician or health professional with victim.
INHALATION: If the vapors from the heated material are inhaled, remove victim to fresh air. If necessary, use artificial
respiration to support vital functions. Victim must seek immediate medical attention if any adverse effect continues after
removal to fresh air.
SKIN EXPOSURE: For contaminations which are associated with routine chemical use and which contaminate a small
area of the skin, wash skin thoroughly with soap and water. If irritation develops or persists, consult a physician. For
major contaminations, begin decontamination with running water for at least 15 minutes. Remove exposed or
contaminated clothing, taking care not to contaminate eyes. Victims should seek immediate medical attention. If the hot
material contaminates the skin, immediately begin decontamination with running water for at least 15 minutes. Treat
exposure areas for burns. Victim should seek medical attention if irritation or other adverse effects occur.
EYE EXPOSURE: If either the heated product or the cooled, semi-solid enters the eyes, open victim's eyes while under
gentle running water. Use sufficient force to open eyelids. Have victim "roll" eyes. Minimum flushing is for 15 minutes.
Victim should seek immediate medical attention.
INGESTION: If this product is swallowed, CALL PHYSICIAN OR POISON CONTROL CENTER FOR MOST CURRENT
INFORMATION. DO NOT INDUCE VOMITING unless directed by medical personnel. Have victim rinse mouth with water, if
conscious. Never induce vomiting or give a diluent (e.g., water) to someone who is unconscious, having convulsions, or
unable to swallow. If contaminated individual is convulsing, maintain an open airway and obtain immediate medical attention.
RECOMMENDATIONS TO PHYSICIANS: Treat symptoms and eliminate overexposure.
MEDICAL CONDITIONS AGGRAVATED BY EXPOSURE: Pre-existing dermatitis, other skin conditions, respiratory
conditions, may be aggravated by overexposure to this product.

pregnant rats to concentrations greater than 500 ppm resulted in fetotoxic effects (e.g. reduced birth weights, delay in bone
formation).
Reproductive Toxicity: This product is not reported to cause reproductive effects in humans. Clinical studies on test
animals exposed to relatively high doses of the Benzene, Ethyl Benzene, Toluene and Xylene components of this product
provided reproductive toxicity data.
A mutagen is a chemical that causes permanent changes to genetic material (DNA) such that the changes will propagate
through generational lines. An embryotoxin is a chemical that causes damage to a developing embryo (i.e. within the first
eight weeks of pregnancy in humans), but the damage does not propagate across generational lines. A teratogen is a
chemical that causes damage to a developing fetus, but the damage does not propagate across generational lines. A
reproductive toxin is any substance that interferes in any way with the reproductive process.

ALL WORK PRACTICES MUST BE AIMED AT ELIMINATING ENVIRONMENTAL CONTAMINATION.
ENVIRONMENTAL STABILITY: Hydrocarbon and cycloalkanes are the main components of this product and are rapidly
volatilized from soil and water sources. They are not photolyzed or hydrolyzed to any great extent. The biodegradation of
both an n-alkane and several carboxylated cycloalkanes was examined within tailings produced by the extraction of
bitumen from the Athabasca oil sands. The carboxylated cycloalkanes examined were structurally similar to naphthenic
acids that have been associated with the acute toxicity of oil sand tailings. The biodegradation potential of naphthenic
acids was estimated by determining the biodegradation of both the carboxylated cycloalkanes and hexadecane in oil sand
tailings. Carboxylated cycloalkanes were biodegraded within oil sand tailings, although compounds with methyl
substitutions on the cycloalkane ring were more resistant to microbial degradation. Microbial activity against hexadecane
and certain carboxylated cycloalkanes was found to be nitrogen and phosphorus limited.
