=====================  Hazards Identification  =====================

LD50 LC50 Mixture:NONE SPECIFIED BY MANUFACTURER.
Routes of Entry: Inhalation:YES  Skin:YES  Ingestion:NO
Reports of Carcinogenicity:NTP:YES    IARC:YES	  OSHA:NO
Health Hazards Acute and Chronic:ACUTE: CNTCT W/HOT ASPHALT CAN CAUSE
    SEV THERMAL BURNS. VAPS CAN IRRITATE EYES/SKIN. INHAL OF FUMES FROM
    HOT ASPHALT CAN CAUSE NAUS & IRRIT OF NOSE & THROAT. EXPOS TO
    ASPHALT FUMES CAN CAUSE DERM & CA N PHOTOSENSITIZE SKIN, MAKING IT
    MORE SUSCEPTIBLE TO ADVERSE EFTS OF SUNLIGHT. CAUTION! UNDER
    CERTAIN (EFTS OF OVEREXP)
Explanation of Carcinogenicity:SILICA, CRYSTALLINE-QUARTZ: IARC MONO,
    VOL 68, 1997:GROUP 1. NTP 7TH ANNUAL REPORT ON CARCINS, 1994:ANTIC
    TO BE CARCIN.
Effects of Overexposure:HLTH HAZ: CIRCUMSTANCES, HYDROGEN SULFIDE
    (H*2S; CAS #7783-06-4), A HIGHLY FLAM & TOX GAS MAY BE RELS FROM
    MOLTEN ASPHALT. H*2S IS COLORLESS GAS W/ODOR SIMILAR TO ROTTEN
    EGGS. ODOR CANNOT BE RELIED ON  AS MEANS OF DETECTION BECAUSE SENSE
    OFSMELL RAPIDLY BECOMES INSENSITIVE TO IT. IN ADD, H*2S ODOR MAY BE
    (SUPDAT)
Medical Cond Aggravated by Exposure:INHALATION OF RESPIRABLE DUSTS MAY
    AGGRAVATE EXISTING RESPIRATORY TRACT DISEASES OR PULMONARY
    DYSFUNCTION. EXPOSURE TO DUST MAY AGGRAVATE EXISTING EYE OR SKIN
    CONDITIONS.

=======================  First Aid Measures  =======================

First Aid:INGEST: CALL MD IMMED . EYES: IF HOT ASPHALT SPLASHES INTO
    EYES, IMMED FLUSH W/COPIOUS AMTS OF WATER FOR AT LEAST 15 MIN. DO
    NOT ATTEMPT TO REMOVE PARTICLES OF ASPHALT FROM EYES. OBTAIN MED
    ATTN  IMMED. SKIN: IF MOLTEN ASPHALT CONTACTS SKIN, COOL IMMED BY
    QUENCHING W/COLD WATER. FOR EXTENSIVE BURNS, COVER W/STERILE
    DRESSING. DO NOT USE SOLVS TO REMOVE ASPHALT FROM SKIN. OBTAIN MED
    (ING 11)

=====================  Fire Fighting Measures  =====================

Flash Point:>450F,>232C
Extinguishing Media:DRY CHEMICAL, CARBON DIOXIDE, FOAM, WATER FOG.
Fire Fighting Procedures:USE NIOSH APPROVED SCBA AND FULL PROTECTIVE
    EQUIPMENT . DURING A FIRE, IRRITATING & HIGHLY TOXIC GASES AND
    FUMES CAN EVOLVE.
Unusual Fire/Explosion Hazard:WATER MAY CAUSE FROTHING.

==================  Accidental Release Measures  ==================

Spill Release Procedures:SHUT OFF ALL IGNITION SOURCES. CONTAIN SPILLED
    MATERIAL AND DO NOT ALLOW TO FLOW INTO PUBLIC SEWERS OR WATER
    SYSTEMS. ALLOW MATERIAL TO HARDEN AND TRANSFER INTO CONTAINER FOR
    PROPER DISPOSAL.
Neutralizing Agent:NONE SPECIFIED BY MANUFACTURER.

======================	Handling and Storage  ======================

Handling and Storage Precautions:USE IN WELL-VENTD AREAS. HIGHLY FLAM.
    AVOID INHAL OF FUMES! CNTCT W/HOT ASPHALT CAN CAUSE SEV BURNS! KEEP
    IGNIT SOURCES AWAY FROM VENTS & (ING 13)
Other Precautions:DO NOT STORE NEAR HEAT, SPARKS, FLAME OR STRONG
    OXIDANTS. DUSTS CREATED BY DRILLING/GRINDING CURED ASPHALT MAY
    IRRITATE EYES & RESPIRATORY TRACT. FOR SUCH OPERATIONS, USE NIOSH
    APPROVED RESPIRATORS &  AVOID BREATHING DUSTS.

=============  Exposure Controls/Personal Protection  =============

Respiratory Protection:A NIOSH APPROVED RESPIRATOR IS REQUIRED IF A TLV
    IS EXCEEDED: SUPPLIED AIR RESPIRATORS MUST BE USED IF STANDARD FOR
    HYDROGEN SULFIDE IS EXCEEDED OR WHEN ENTERING CONFINED OR ENCLOSED
    SPACES WHERE HYDR OGEN SULFIDE MAY BE PRESENT.
Ventilation:USE ONLY IN WELL VENTILATED AREAS. USE EXPLOSION-PROOF
    EQUIPMENT.
Protective Gloves:IMPERVIOUS GLOVES .
Eye Protection:ANSI APPRVD CHEM WORKERS GOGGS (ING 14)
Other Protective Equipment:ANSI APPRVD EYE WASH & DELUGE SHOWER. CHEM
    RESIST APRON. LOOSE CLTHG W/NECK CLSD, SLEEVES ROLLED DOWN. SFTY
    SHOES.
Work Hygienic Practices:REMOVE DUST FROM EXPOSED SKIN WITH SOAP AND
    WATER. WASH CLOTHING.
Supplemental Safety and Health
APPEAR/ODOR: ASPHALT ODOR. EFTS OF OVEREXP: MASKED BY GEN ODOR OF HOT
    ASPHALT. LOW CONCS (50-100 PPM) OF H*2S CAN IRRIT EYES & RESP TRACT
    & MAY CAUSE NERVOUSNESS, COUGH, NAUS & HDCH. PRLNGD EXPOS TO C ONCS
    BETWEEN 250-600 PPM MAY CAUSE PULMEDEMA (FLUID IN LUNGS) &
    BRONCHIAL PNEUM. BRIEF EXPOS TO CONCS ABOVE (ING 4)
