* Flammable chemicals with an asterisk are not specifically listed in 1910.119 appendix A, but do meet the criteria in 1910.1200 (c) to be regulated under 1910.119 as a flammable chemical with a threshold quantity of 10,000 lbs. Those criteria state that a flammable gas must have a Lower Explosive (flammability) Limit (LEL)of 13% or less at ambient temperature and pressure and a flammable liquid must have a flashpoint less than 100 degrees F to covered by 1910.119. If you have one of these flammable chemicals with an asterisk by it that does not meet these specifications to be regulated under the OSHA PSM standard, then DEQ may request that you provide a valid Material Safety Data Sheet for that chemical listing the LEL or Flashpoint. The National Fire Protection Association Guide to Hazardous Materials, Code 325, sections 1-3.3 and 1-3.5 lists the definitions for Flashpoint and LEL.
