MATERIAL SAFETY DATA SHEET Diesel Fuel - High Sulfur
Further information : Exposure to decomposition products may be a hazard to health. Isolate area
around container involved in fire. Cool tanks, shells, and containers exposed to fire
and excessive heat with water. For massive fires the use of unmanned hose
holders or monitor nozzles may be advantageous to further minimize personnel
exposure. Major fires may require withdrawal, allowing the tank to burn. Large
storage tank fires typically require specially trained personnel and equipment to
extinguish the fire, often including the need for properly applied fire fighting foam.
SECTION 6. ACCIDENTAL RELEASE MEASURES
Personal precautions : Consider wind direction; stay upwind and uphill, if possible. Evacuate nonessential
personnel and remove or secure all ignition sources. Evaluate the direction of
product travel, diking, sewers, etc. to contain spill areas. Spills may infiltrate
subsurface soil and groundwater; professional assistance may be necessary to
determine the extent of subsurface impact. Ensure adequate ventilation. Use
personal protective equipment.
Environmental precautions : Carefully contain and stop the source of the spill, if safe to do so. Do not flush
down sewer or drainage systems, unless system is designed and permitted to
handle such material. The use of fire fighting foam may be useful in certain
situations to reduce vapors. The proper use of water spray may effectively
disperse product vapors or the liquid itself, preventing contact with ignition sources
or areas/equipment that require protection. Discharge into the environment must
be avoided. If the product contaminates rivers and lakes or drains inform
respective authorities.
Methods for cleaning up : Take up with sand or oil absorbing materials. Carefully shovel, scoop or sweep up
into a waste container for reclamation or disposal - caution, flammable vapors may
accumulate in closed containers. Response and clean-up crews must be properly
trained and must utilize proper protective equipment (see Section 8).

SECTION 7. HANDLING AND STORAGE
Handling : Keep away from fire, sparks and heated surfaces. No smoking near areas where
material is stored or handled. The product should only be stored and handled in
areas with intrinsically safe electrical classification.
Advice on protection against : Hydrocarbon liquids including this product can act as a non-conductive flammable
fire and explosion liquid (or static accumulators), and may form ignitable vapor-air mixtures in storage
tanks or other containers. Precautions to prevent static-initated fire or explosion
during transfer, storage or handling, include but are not limited to these examples:
(1) Ground and bond containers during product transfers. Grounding and
bonding may not be adequate protection to prevent ignition or explosion of
hydrocarbon liquids and vapors that are static accumulators.
(2) Special slow load procedures for "switch loading" must be followed to
avoid the static ignition hazard that can exist when higher flash point
material (such as fuel oil or diesel) is loaded into tanks previously
containing low flash point products (such gasoline or naphtha).
(3) Storage tank level floats must be effectively bonded.
