Lip Techinicail B.Rullefiii 41111 HEAT CONTENT OF BURNER AND DIESEL FUELS The "heat content" or Heat of Combustion of distillate fuels is correlated to the API Gravity (i.e. fuel density) and is influenced by sulfur content. Although heat of combustion best can be determined experimentally, usually it is estimated by calculation.

Gross heat of combustion is the more commonly used, It Is the l'eat released by the combustion of the fuel with all of the water formed condensed to a liquid state. Net heat of combustion is the heat released by combuslion of the fuel with the water remaining in the vapor state.

The calculated values in this table may differ from determined \Elues by up to 6-1 Btu's per pound.

Skin contact Take off all contaminated clothing immediately. Wash off immediately with soap and plenty of water. Wash contaminated clothing before re-use. If skin irritation persists, seek medical attention immediately.

Eye contact Remove contact lenses. Rinse immediately with plenty of water, also under the eyelids, for at least 15 minutes. If eye irritation persists, seek medical attention.

Ingestion Do not induce vomiting without medical advice. If a person vomits when lying on his back, place him in the recovery position. Seek medical attention immediately.

Special protective equipment Wear self-contained breathing apparatus and protective suit. Use personal for fire-fighters protective equipment.

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 2/10

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 Evacuate nonessential personnel and remove or secure all ignition sources.

Consider wind direction; stay upwind and uphill, if possible. 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. Protect bodies of water by diking, absorbents, or absorbent boom, if possible. 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).

Handle and open container with care. Use only intrinsically safe electrical equipment approved for use in classified areas. Do not smoke near areas where material is handled or stored. Remove all sources of ignition. Emergency eye wash capability should be available in the vicinity of any potential splash exposure.

Advice on protection against Keep away from sources of ignition - No smoking. Ground and bond containers fire and explosion during product transfers to reduce the possibility of static-initiated fire or explosion.

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) is loaded into tanks previously containing low flash point products - see API Publication 2003, "Protection Against Ignitions Arising Out Of Static, Lightning and Stray Currents."

Empty product containers or vessels may contain explosive vapors. Do not pressurize, cut, heat, weld or expose containers to sources of ignition. Store in a well-ventilated area. This storage area should comply with NFPA 30 "Flammable and Combustible Liquid Code". Avoid storage near incompatible materials. The cleaning of tanks previously containing this product should follow API Recommended Practice (RP) 2013 "Cleaning Mobile Tanks In Flammable and Combustible Liquid Service" and API RP 2015 "Cleaning Petroleum Storage Tanks".

Advice on common storage Keep away from food, drink and animal feed. Incompatible with oxidizing agents.

Incompatible with acids.

Eye protection Safety glasses or goggles are recommended where there is a possibility of splashing or spraying.

Hand protection Gloves constructed of nitrile, neoprene, or PVC are recommended. Consult manufacturer specifications for further information.

Skin and body protection If needed to prevent skin contact, chemical protective clothing such as of DuPont TyChem, Saranex or equivalent recommended based on degree of exposure.

Respiratory protection A NIOSH/ MSHA-approved air-purifying respirator with organic vapor cartridges or canister may be permissible under certain circumstances where airborne concentrations are or may be expected to exceed exposure limits or for odor or irritation. Protection provided by air-purifying respirators is limited. Refer to OSHA 29 CFR 1910.134, ANSI Z88.2-1992, NIOSH Respirator Decision Logic, and the manufacturer for additional guidance on respiratory protection selection. Use a NIOSH/ MSHA-approved positive-pressure supplied-air respirator if there is a potential for uncontrolled release, exposure levels are not known, in oxygen-deficient atmospheres, or any other circumstance where an air-purifying respirator may not provide adequate protection.

Hygiene measures Avoid repeated and/or prolonged skin exposure. Use good personal hygiene practices. Wash hands before eating, drinking, smoking, or using toilet facilities.

DO NOT use gasoline, kerosene, solvents, or harsh abrasive skin cleaners to clean skin. Waterless hand cleaners are effective. Promptly remove contaminated clothing and launder before reuse. Consider disposal of contaminated clothing rather than laundering to prevent the formation of flammable vapors which could ignite via washer or dryer.
