This product does not contain any materials listed by OSHA, NTP, or IARC as carcinogens.



SECTION III. HEALTH HAZARD INFORMATION



      CAUTION! HEATING MAY RELEASE HYDROGEN SULFIDE GAS (H2S)





EYE CONTACT: The cool material will cause minor eye irritation. However, thermal burns

may result form contact with the hot material. The degree of the injury will depend on the

amount of material that gets into the eye and the speed and thoroughness of the first aid

treatment. Signs and symptoms may include, pain, tears, swelling, redness and blurred

vision. This hazard evaluation is based on the data from similar materials.



SKIN CONTACT: The cool material will cause minor skin irritation. However, thermal

burns may result from contact with the hot material. The degree of the injury will depend on

the amount of material that gets on the skin and the speed and thoroughness of the first aid

treatment. Signs and symptoms may include: pain, discoloration and swelling. This hazard

evaluation is based on data from similar materials.

The systemic toxicity of this substance has not been determined. However, it should be

practically non-toxic to internal organs if it gets into the skin.



INHALATION: Fumes from the hot material can be unpleasant and may produce nausea

and irritation of the upper respiratory tract. If inhaled, this substance is considered

practically non-toxic to internal organs. This substance contains sulfur compounds which

may form hydrogen sulfide. the rotten eggs odor of hydrogen sulfide is unreliable as an

indicator of concentration. Signs and symptoms of over exposure to hydrogen sulfide

include respiratory tract irritation, headaches, dizziness, nausea, gastrointestinal

disturbances, coughing, a sensation of dryness and pain in the nose, throat and chest,

confusion and unconsciousness. Hydrogen sulfide concentrations of 1000 -2000 ppm can be

extremely hazardous. This hazard evaluation is based on data from similar materials.



INGESTION: This is an unlikely route of entry, however if swallowed, this substance is

considered practically non-toxic.



ADDITIONAL HEALTH DATA COMMENT: Studies in which mice were exposed to a

variety of whole asphalts did not result in any increased cancer rate; mice exposed to

asphalts diluted with hydrocarbon solvents had increased incidence of certain types of

cancer. Brief or intermittent skin contact with this asphalt product is not expected to produce

any delayed effects. While normal handling of this product is not likely to cause cancer in

humans, skin contact and breathing of mists or vapors should be reduced to a minimum.



FIRST AID: EYE CONTACT: Flush eyes, including under eyelids, with running water for

at least fifteen minutes. Get medical attention. SKIN CONTACT: If the hot, melted material

gets on the skin, quickly cool in water. See a doctor for extensive burns. DO NOT try to

peel the solidified material form the skin or use solvents or thinners to dissolve it. The use of

vegetable oil or mineral oil is recommended for removal of this material from the skin.

Flush exposed area with water while removing contaminated clothing. Get medical attention

if irritation persists. INHALATION: : If there are signs or symptoms of hydrogen sulfide

exposure(respiratory tract irritation, headache, dizziness, nausea, gastrointestinal

disturbances, coughing, a sensations of dryness or pain in the nose, throat and chest,

confusion and unconsciousness), move the person to fresh air. If breathing has stopped,

apply artificial respiration. Call a doctor. Note to physician: In addition to the use of 100%

oxygen and supportive care, suggested treatment for hydrogen sulfide poisoning includes

the use of nitrites. This is based on the similar mechanisms of toxicity between hydrogen

sulfide and hydrogen cyanide. The nitrite-induced methemoglobin is thought to bind the

toxic hydrosulfide ion. Initial inhalation of amyl nitrite pearls for 15 to 30 seconds if each

minute should be initiated until 10 ml of a 3% solution of sodium nitrite can be administered

intravenously at 2.5 to 5 ml per minute. While the efficacy of nitrites in hydrogen sulfide

poisoning has not been unequivocally demonstrated, their use is recommended as part of the

treatment regimen. Hyperbaric oxygen therapy has been used for cyanide poisoning with

some success and may be of benefit in hydrogen sulfide poisoning if other measures are

ineffective. INGESTION: Unlikely, if occurs give person milk or water. Keep head below

the waist. Contact a physician or Poison Control Center. Never give anything by mouth to a

person who is unconscious or having convulsions.



                 NFPA RATING: HEALTH - 1 FIRE - 2 REACTIVITY - 0



SECTION IV. FIRE AND EXPLOSION DATA



FLASH POINT AND METHOD: ~ 110 °F Tag open cup

UPPER EXPLOSIVE LIMIT: Not Available

LOWER EXPLOSIVE LIMIT: Not Available



EXTINGUISHING MEDIA: Water, carbon dioxide and dry chemical. Use water spray to

cool fire-exposed containers. A fine water mist may be used to smother fire or to disperse

vapors. Do not use a solid stream of water since the stream will scatter and spread the fire.

Fire fighters must wear self-contained breathing apparatus and full protective clothing when

fighting fires involving this material.



SECTION V. REACTIVITY DATA



CAUTION! HEATING MAY RELEASE HYDROGEN SULFIDE GAS (H2S)



This material is stable in closed containers at room temperature under normal storage and

handling conditions. It does not polymerize. It is incompatible with strong oxidizing agents.

Decomposition products can include carbon monoxide, carbon dioxide, and water vapor.



SECTION VI. PHYSICAL DATA



BOILING POINT: ~ 650 °F

APPEARANCE AND ODOR: Black liquid with organic odor



SECTION VII. SPILL, LEAK, AND DISPOSAL PROCEDURE



Notify safety personnel of large spills or leaks. Clean-up personnel need protection against

liquid contact and vapor inhalation. Absorb small spills and collect liquid, if feasible, or

absorb with vermiculite or sand. Do not flush to sewer or stream.

Dispose of liquid waste via licensed waste disposal company. Follow Federal, State and

Local regulation.



SECTION VIII. SPECIAL PROTECTION INFORMATION





Wear impervious gloves and safety glasses to prevent contact with the skin and eyes. If

repeated or prolonged contact with liquid is likely, wear protective clothing including boots,

apron, and faceshield or splash goggles. Remove contaminated clothing immediately and do

not reuse until it has been properly laundered.

Eye wash stations and safety showers should be available in use and handling areas.

Contact lenses pose a special hazard; soft lenses may absorb and all lenses concentrate

irritants.



SECTION IX. SPECIAL PRECAUTIONS AND COMMENTS



Store in closed containers in a cool, dry, well-ventilated area away from oxidizers, heat and

open flame.

Protect container from physical damage.
