SUBMITTER: KiOR, Inc.
USE:

MSDS: Yes Label: No Gen Eqpt: Eye Protection: For general work, use a minimum of safety glasses with side shields. Where a spray, mist or heavy vapor may exist, use chemical safety goggles. Although face shields can be used to supplement the level of protection, they should never be used instead of primary eye protection. Skin Protection: Wear impervious protective clothing, including boots, gloves, apron or coveralls, as appropriate, to prevent skin contact. Respirator: Where vapors are present and engineering controls have been unsuccessful or not available, use NIOSH approved respiratory protection to mitigate potential respiratory exposures. Health Effects: Acute exposure to this material may result in irritation to the skin, eyes and respiratory system. Ingestion will also result in gastrol-intestinal tract irritation. It is also possible for an acute exposure to result in a sensitization response. Inhalation of large quantities may also result in central nervous system depression. TLV/PEL: none established
