MATERIAL A SHEET <br />Diesel Fuel e�s_ MSDS No. 9909 <br />Electricity in Petroleum Fuel Systems" address special precautions and design requirements involving <br />loading rates, grounding, bonding, filter installation, conductivity additives and especially the hazards <br />associated with "switch loading." ["Switch Loading" is when a higher flash point product (such as diesel) <br />is loaded into tanks previously containing a low flash point product (such as gasoline) and the electrical <br />charge generated during loading of the diesel results in a static ignition of the vapor from the previous <br />cargo (gasoline).] <br />Note: When conductivity additives are used or are necessary the product should achieve 25 <br />picosiemens/meter or greater at the handling temperature. <br />STORAGE PRECAUTIONS <br />Keep away from flame, sparks, excessive temperatures and open flame. Use approved vented <br />containers. Keep containers closed and clearly labeled. Empty product containers or vessels may contain <br />explosive vapors. Do not pressurize, cut, heat, weld or expose such containers to sources of ignition. <br />Store in a well -ventilated area. This storage area should comply with NFPA 30 "Flammable and <br />Combustible Liquid Code". Avoid storage near incompatible materials. The cleaning of tanks previously <br />containing this product should follow API Recommended Practice (RP) 2013 "Cleaning Mobile Tanks In <br />Flammable and Combustible Liquid Service" and API RP 2015 "Cleaning Petroleum Storage Tanks". <br />WORK/HYGIENIC PRACTICES <br />Emergency eye wash capability should be available in the near proximity to operations presenting a <br />potential splash exposure. Use good personal hygiene practices. Avoid repeated and/or prolonged skin <br />exposure. Wash hands before eating, drinking, smoking, or using toilet facilities. Do not use as a <br />cleaning solvent on the skin. Do not use solvents or harsh abrasive skin cleaners for washing this product <br />from exposed skin areas. Waterless hand cleaners are effective. Promptly remove contaminated <br />clothing and launder before reuse. Use care when laundering to prevent the formation of flammable <br />vapors which could ignite via washer or dryer. Consider the need to discard contaminated leather shoes <br />and gloves. <br />EXPOSURE LIMITS <br />Exposure Limits <br />Components (CAS No.) Source TWA/STEL Note <br />OSHA 5 mg/m, as mineral oil mist <br />Diesel Fuel: (68476-34-6) ACGIH 100 m /m'(as totally hydrocarbon vapor) TWA <br />A3 skin <br />----------------------------------------------------------------------------------------------------------------------------- <br />OSHA 10 ppm TWA <br />Naphthalene (91-20-3) ACGIH 10 ppm TWA / 15 ppm STEL A4, Skin <br />- - <br />RING - --C-- -O-N- T--ROLS -- — -------------------------------------------------------------------------------------- <br />ENGINEE <br />Use adequate ventilation to keep vapor concentrations of this product below occupational exposure and <br />flammability limits, particularly in confined spaces. <br />EYE/FACE PROTECTION <br />-- Safety glasses or goggles are recommended where there is a possibility of splashing or spraying. <br />SKIN PROTECTION <br />Gloves constructed of nitrile, neoprene, or PVC are recommended. Chemical protective clothing such as <br />of E. I. DuPont TyChem®, Saranex® or equivalent recommended based on degree of exposure. Note: <br />The resistance of specific material may vary from product to product as well as with degree of exposure. <br />Consult manufacturer specifications for further information. <br />Revision Date: 10/18/2006 Page 4 of 7 <br />
