|
|
The National Institute for Occupational
Safety and Health (NIOSH) has concluded that fumes
of heated asphalt are a potential occupational
carcinogen. Do not heat or burn this product.

EMERGENCY OVERVIEW:
WARNING!
COMBUSTIBLE
VAPORS, MISTS OR FUMES MAY IRRITATE THE EYES AND RESPIRATORY TRACT MAY CAUSE CENTRAL NERVOUS SYSTEM DEPRESSION DIRECT CONTACT MAY CAUSE EYE AND SKIN IRRITATION HEATING MAY RELEASE TOXIC HYDROGEN SULFICE GAS (H�S) WHICH MAY ACCUMULATE IN CONFINED SPACES ASPIRATION HAZARD IF SWALLOWED. ASPHALT MAY CONTAIN COMPONENTS THAT ARE SKIN CANCER HAZARDS.
Potential Health Effects
EYE CONTACT: May cause eye irritation resulting in tearing, stinging, redness or swelling. Vapors, mists, or fumes may be irritating.
SKIN CONTACT: May cause skin irritation. Redness, drying and cracking of the skin (dermatitis), may occur following prolonged and repeated contact. In a reported to cause an acne-like skin condition, skin discoloration, and my increase sensitivity to the sun (photosensitization).
SKIN ABSORPTION: Not expected to be significant with short-term skin contact. However, prolonged or repeated skin contact may result in absorption of hazardous components.
INGESTION: In general, asphalt products have low toxicity when swallowed. However, this product may cause irritation of the digestive tract followed by vomiting and central nervous system depression (see �Inhalation� for symptoms). If vomiting occurs, small amounts of material can be aspirated into the lung and cause inflammation or damage with chemical pneumonia.
INHALATION: Exposure to fumes, vapors or mists may cause irritation of the nose and throat, and possible signs of central nervous system depression (symptoms may include headache, excitation, dizziness, loss of coordination, and drowsiness). Loss of consciousness can occur in poorly ventilated or confined spaces.
Additional signs and symptoms of exposure may include reduced appetite and abnormal fatigue. Use of this product in well-ventilated working conditions is not expected to cause adverse effects.
NOTE: Hydrogen sulfide (H2S), an extremely toxic gas, may be emitted from heated asphalt and may accumulate in storage tanks and other confined spaces. At low concentrations, H2S is irritating to the eyes, nose and throat, and at high concentrations (>500 ppm) 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.
MEDICAL CONDITIONS AGGRAVATED BY EXPOSURE
Pre-existing medical conditions that may be aggravated by exposure include disorders of the skin and respiratory tract including asthma.

From MSDS
This product contains petroleum asphalt. Petroleum asphalt is not listed as a The International Agency for Research on Cancer (IARC) has determined there is inadequate evidence that asphalt alone is carcinogenic to humans, and that there is inadequate evidence for the carcinogenicity of undiluted air-refined asphalts in experimental animals. The National Institute of Occupational Safety and Health (NIOSH) has concluded that at higher temperatures roofing occupational carcinogen. If this product is heated or comes in contact with heated material, avoid breathing fumes.
This material contains a hydrocarbon solvent. When dissolved in hydrocarbon solvents, asphalt has produced skin tumors in animals following prolonged and repeated contact. Consequently, IARC has determined that there is sufficient evidence that extracts or cutbacks (asphalts dissolved in hydrocarbon
solvents) are carcinogenic to experimental animals.
This product may contain small amounts of polyaromatic hydrocarbons which are recognized carcinogens in humans and experimental animals.
This material contains a hydrocarbon solvent. Reports have associated prolonged or repeated occupational overexposure to solvents with permanent brain and nervous system damage (sometimes referred to as �Solvent or Painters Syndrome�. Intentional misuse by deliberately inhaling vapors of this product may be harmful or fatal.
This product contains small amounts of respirable crystalline silica (quartz and cristobalite). IARC and NTP have determined that there is sufficient evidence for the carcinogenicity of respirable crystalline silica in experimental animals and limited evidence for its carcinogenicity in humans. The presence of crystalline silica in this product is not expected to present an inhalation hazard since the material is not a dust and is typically troweled onto a surface and allowed to harden. In addition, the hardened product is not anticipated to present a health hazard unless is subjected to mechanical forces including grinding, drilling, or other demolition work. In such cases, the silica may be liberated in dust form. Prolonged and repeated exposure to respirable silica-containing dust may have serious lung effects, including silicosis, bronchitis, and lung cancer.
WARNING: This product contains a chemical known to the State of California to cause cancer and birth defects or other reproductive harm.

From MSDS
EYE CONTACT:
Immediately flush eyes with plenty of water for at least 15 minutes, occasionally lifting the eye lids to ensure thorough rinsing. Get medical attention if irritation persists. Get immediate medical attention if there is direct eye contact with hot material.
SKIN CONTACT:
Clean exposed skin with warm soapy water. Use a waterless hand cleaner to help remove the asphalt. Do not use solvents or thinners to remove material from skin. Get medical attention if irritation persists or develops.
INGESTION:
If swallowed, do not induce vomiting because of danger of aspirating material into lungs, resulting in damage and chemical pneumonia. Never give anything by mouth to an unconscious person. If vomiting occurs, keep head lower than hips to prevent aspiration. Get immediate medical attention.
INHALATION:
If inhalation overexposure to vapors, mists, or fumes occurs, remove person to fresh air. If not breathing, give artificial respiration or give oxygen by trained personnel. Get immediate medical attention.
NOTES TO PHYSICIAN:
Medical personnel can soften and remove asphalt with petroleum jelly or white mineral oil. In general, emesis induction is unnecessary in high viscosity products. Also contains mineral spirits that, when aspirated into the lung, may result in chemical pneumonia. If large volumes have been swallowed, gastric lavage should be considered. Patients may be predisposed to pneumonia during convalescence, and should be kept under observation. Inhalation exposure of hydrogen sulfide may also result in pulmonary congestion. Contact a Poison Center for additional treatment information.

Handling/Disposal
|
From MSDS
Store away from heat and all ignition sources and open flames in accordance with applicable laws and regulations.
Avoid all ignition sources. Storage areas should be ventilated to reduce fire and explosion hazards, and possible overexposure of personnel to fumes and vapors . Keep containers closed when not in use. Do not store near food and beverages or smoking
materials.
NOTE: Hydrogen sulfide (H2S), an extremely toxic gas, may be emitted from heated asphalt and may accumulate in storage tanks and other confined spaces. Empty containers retain residue (liquid and/or vapor) and can be dangerous. DO NOT PRESSURIZE, CUT, WELD, BRAZE, SOLDER, DRILL, GRIND OR EXPOSE SUCH CONTAINERS TO HEAT, FLAME, SPARKS, OR OTHER SOURCES OF IGNITION. THEY MAY EXPLODE AND CAUSE INJURY OR DEATH. Do not attempt to clean since residue is difficult to remove.
