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

First Aid:INGEST: CALL MD IMMED . SKIN: IF BURNED BY HOT PROD, OBTAIN
    MED ATTN IMMED. IN CASE OF SKIN CONTACT W/PROD UNDER OTHER CNDTNS,
    WASH THOROUGHLY W/SOAP & WARM WATER. REMOVAL OF PROD FROM SKIN MAY 
    BE AIDED BY USE OF WATERLESS HANDCLEANER. IF HOT PROD IS SPLASHED
    INTO EYES, FLUSH W/CLEAR WATER FOR AT LEAST 15 MIN & CONTACT MD
    IMMED. IF OVERCOME BY H*2S, IMMED REMOVE TO FRESH AIR & CALL (ING
    9)

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

Extinguishing Media:DRY CHEMICAL, FOAM OR CARBON DIOXIDE PREFERRED.

Neutralizing Agent:NONE SPECIFIED BY MANUFACTURER.

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

Handling and Storage Precautions:WHEN ASPHALTIC PRODS ARE HEATED, THEY
    OFTEN GIVE OFF SMALL AMTS OF HYDROGEN SULFIDE, AN EXTREMELY FLAM,
    HIGHLY TOXIC GAS. BREATHING HYDROGEN (ING 10)
Other Precautions:BREATHING ASPHALT AEROSOL OR ASPHALT SMOKE FOR
    PROTRACTED PERIODS OF TIME HAS PRODUCED DMG TO LUNGS OF MICE. AMONG
