DOT Emergency Response Guidebook (ERG 2004)
Guide Number: 128
128 Flammable Liquids (Non-Polar/Water-Immiscible)
*       HIGHLY FLAMMABLE: Will be easily ignited by heat, sparks or flames.
*       Vapors may form explosive mixtures with air.
*       Vapors may travel to source of ignition and flash back.
*       Most vapors are heavier than air. They will spread along ground and
        collect in low or confined areas (sewers, basements, tanks).
*       Vapor explosion hazard indoors, outdoors or in sewers.
*       Those substances designated with a P may polymerize explosively when
        heated or involved in a fire.
*       Runoff to sewer may create fire or explosion hazard.
*       Containers may explode when heated.
*       Many liquids are lighter than water.
*       Substance may be transported hot.
*       Inhalation or contact with material may irritate or burn skin and eyes.
*       Fire may produce irritating, corrosive and/or toxic gases.
*       Vapors may cause dizziness or suffocation.
*       Runoff from fire control or dilution water may cause pollution.
*       CALL Emergency Response Telephone Number on Shipping Paper first. If
        Shipping Paper not available or no answer, refer to appropriate
        telephone number listed on the inside back cover.
*       Isolate spill or leak area immediately for at least 25 to 50 meters
        (80 to 160 feet) in all directions.
*       Keep unauthorized personnel away.
*       Stay upwind.
*       Keep out of low areas.
*       Ventilate closed spaces before entering.
*       Wear positive pressure self-contained breathing apparatus (SCBA).
*       Structural firefighters' protective clothing will only provide limited
Large Spill
*       Consider initial downwind evacuation for at least 300 meters
        (1000 feet).
*       If tank, rail car or tank truck is involved in a fire, ISOLATE for
        800 meters (1/2 mile) in all directions; also, consider initial
        evacuation for 800 meters (1/2 mile) in all directions.
CAUTION: All these products have a very low flash point: Use of water spray
         when fighting fire may be inefficient.
Small Fires
*       Dry chemical, CO2, water spray or regular foam.
Large Fires
*       Water spray, fog or regular foam.
*       Use water spray or fog; do not use straight streams.
*       Move containers from fire area if you can do it without risk.
Fire involving Tanks or Car/Trailer Loads
*       Fight fire from maximum distance or use unmanned hose holders or
        monitor nozzles.
*       Cool containers with flooding quantities of water until well after
        fire is out.
*       Withdraw immediately in case of rising sound from venting safety
        devices or discoloration of tank.
*       ALWAYS stay away from tanks engulfed in fire.
*       For massive fire, use unmanned hose holders or monitor nozzles; if this
        is impossible, withdraw from area and let fire burn.
*       ELIMINATE all ignition sources (no smoking, flares, sparks or flames
        in immediate area).
*       All equipment used when handling the product must be grounded.
*       Do not touch or walk through spilled material.
*       Stop leak if you can do it without risk.
*       Prevent entry into waterways, sewers, basements or confined areas.
*       A vapor suppressing foam may be used to reduce vapors.
*       Absorb or cover with dry earth, sand or other non-combustible material
        and transfer to containers.
*       Use clean non-sparking tools to collect absorbed material.
Large Spills
*       Dike far ahead of liquid spill for later disposal.
*       Water spray may reduce vapor; but may not prevent ignition in closed
*       Move victim to fresh air.
*       Call 911 or emergency medical service.
*       Apply artificial respiration if victim is not breathing.
*       Administer oxygen if breathing is difficult.
*       Remove and isolate contaminated clothing and shoes.
*       In case of contact with substance, immediately flush skin or eyes with
        running water for at least 20 minutes.
*       Wash skin with soap and water.
*       Keep victim warm and quiet.
*       Ensure that medical personnel are aware of the material(s) involved,
        and take precautions to protect themselves.

Additional Emergency Response Information (CAMEO Data)
Non-fire Spill Response: Keep sparks, flames, and other sources of ignition away. Keep material out of water sources and sewers. Build dikes to contain flow as necessary. Attempt to stop leak if without undue personnel hazard. Use water spray to knock-down vapors. ( AAR, 1999)
Firefighting: Do not extinguish fire unless flow can be stopped. Use water in flooding quantities as fog. Solid streams of water may spread fire. Cool all affected containers with flooding quantities of water. Apply water from as far a distance as possible. Use foam, dry chemical, or carbon dioxide. ( AAR, 1999)
Reactivity: This compound is incompatible with the following:None reported [Note: VM&P Naphtha is a refined petroleum solvent predominantly C7-C11 which is typically 55% paraffins, 30% monocycloparaffins, 2% dicycloparaffins & 12% alklybenzenes.] (NIOSH, 1997)
First Aid: Eye: If this chemical contacts the eyes, immediately wash the eyes with large amounts of water, occasionally lifting the lower and upper lids. Get medical attention immediately. Contact lenses should not be worn when working with this chemical. Skin: If this chemical contacts the skin, promptly wash the contaminated skin with soap and water. If this chemical penetrates the clothing promptly remove the clothing and wash the skin with soap and water. Get medical attention promptly. Breathing: If a person breathes large amounts of this chemical, move the exposed person to fresh air at once. If breathing has stopped, perform mouth-to-mouth resuscitation. Keep the affected person warm and at rest. Get medical attention as soon as possible. Swallow: If this chemical has been swallowed, get medical attention immediately. (NIOSH, 1997)
