SUBMITTER: KiOR USE: Used in a manner comparable to gas oil as it is currently used in industry.

. P2REC: CRSS: Forward. P2 Claim: The PMN material is a renewable crude oil substitute created from surplus biomass feedstock. This substitute can be refined and then blended into a variety of transportation fuels. It is compatible with and can be "dropped-in" to our country's existing fuel production and distribution infrastructure and used in vehicles on the road today. The PMN material delivers over 80% reduction in greenhouse gas emissions relative to current gasoline and diesel fuels.

MSDS: Yes Label: No Gen Eqpt: Eng Controls: Activities that heat this material to where a flammable atmosphere may exist must be avoided. If such an activity must be performed, use engineering controls (such as process enclosures or local exhaust ventilation) to maintain airborne contamination levels to a non-hazardous level. Also, when performing such tasks, the use of hazardous classified equipment must be considered. // Eye: For general work, a minimum of safety glasses with side shields should be used. Where a spray, mist or heavy vapor exists, use chemical safety goggles or a full-face respirator. Although face shields can be used to supplement the level of eye protection, face shields should never be used instead of primary eye protection. // Skin: Where realistic exposure exist, impervious protective clothing, including boots, gloves, apron or coveralls, as appropriate to prevent skin contact, should be used. Respirator: Where vapors are present and engineering controls have been unsuccessful or not available, use NIOSH approved respiratory protection to mitigate potential respiratory exposures. Where the concentration of vapors is uncertain, use either a supplied air respirator or a self-contained breathing apparatus (SCBA). Respirators should be used in accordance with OSHA requirements (29 CFR 1910.134). Health Effects: Acute: Mist or vapor may irritate the eyes and respiratory tract. Contact with the skin may result in defatting/drying and, in serious cases of Page 1p110332.eng exposure, possibly dermatitis. // Chronic: Prolonged or repeated exposure to similar materials has resulted in cancer and systemic toxicity. As components (PCAs/PNAs) that are believed to cause the adverse chronic reactions to similar materials are also present in this material, it is assumed that similar exposures to hydrotreated oil residue will produce similar toxic results. Chronic exposure may also result in phototoxic effects. TLV/PEL: Mineral Oil 5 ppm TWA, 8-hr
