MATERIAL SAFETY DATA SHEET <br />CREOSOTE TREATED WOOD <br />PERSONAL PROTECTIVE EQUIPMENT <br />SKIN PROTECTION: <br />Wear necessary protective clothing to protect head, face, neck and uncovered skin from contact with wood dust <br />or preservative. For exposed skin, the application of a commercially available sun -blocking lotion is <br />recommended to greatly reduce the phototoxicity of creosote associated sun burning. The lotion should be <br />applied prior to the application of a barrier cream and should have a sun protection factor (SPF) of 15 or greater. <br />The application of a barrier cream (e.g. Ply 9 Gel, MSA's Fend AE -2, Kerodex 51, Jergens SBS -46) is recommended <br />to prevent coal tar containing products from contacting skin. <br />EYE PROTECTION: Safety glasses, goggles or face shield when power sawing or machining. <br />RESPIRATORY PROTECTION: <br />Not normally required except when handling procedure(s) generate dust. If ventilation does not maintain <br />inhalation exposures below PEL (TLV), use NIOSH /MSHA-approved units as per current 29 CFR 1910.134. If <br />within OSHA protection factor, air purifying OV/filter units are acceptable. Use a NIOSH -approved respirator <br />with suitable particulate cartridge. <br />ADDITIONAL RECOMMENDATIONS: <br />Showering and clothing change is strongly recommended at the end of each work shift. <br />If oily preservatives/ sawdust soil clothes, launder work clothing separately from household clothing before <br />reuse. A complete change of work clothes should be used each day if contaminated. Whenever possible, <br />sawing/ machining treated wood should be performed outdoors to avoid accumulations of airborne treated wood <br />sawdust. <br />Urethane/epoxy/shellac are acceptable sealers for creosote treated wood. Coal tar pitch and coal tar pitch <br />emulsions are effective sealers for creosote treated wood block flooring. <br />EXPOSURE GUIDELINES <br />INGREDIENT NAME <br />Creosote (measured as Coal Tar Pitch Volatiles, CTPV) <br />Wood Dust <br />Hard (certain hardwood species - oak and beech) <br />Soft <br />ACGIH TLV <br />0.2 mg/m3 <br />1 mg/m3TWA <br />OSHA PEL <br />0.2 mg/m3 <br />5 mg/m3 TWA <br />10 mg/m3 STEL <br />5 mg/m3 TWA 5 mg/m3 TWA <br />10 mg/m3 STEL 10 mg/m3 STEL <br />OTHER LIMIT <br />None <br />OTHER EXPOSURE LIMITS FOR POTENTIAL DECOMPOSITION PRODUCTS: <br />Material does not decompose.
