ND = Not determined under normal exposure scenarios.
NOTE THAT VALUES ARE IN mg/m3, NOT ppm.
Lower Explosive Limit (LEL) = 14,000ppm
* = > 10% LEL; ** = > 50% LEL: *** = > 100% LEL
AEGL 2 is higher than 1/10 of the Lower Exposure Limit
For values denoted as * safety considerations against the hazard(s) of explosion(s) must be taken into account.
IMPORTANT NOTE: Proposed AEGLs are established following review and consideration by the National Advisory Committee for AEGLs (NAC/AEGL) of Draft AEGLs. Proposed AEGLs are available for use by organizations while awaiting public comments and NRC/NAS peer review and publication of Final AEGLs. Changes to Proposed values and Technical Support Documents may occur before AEGLs become interim values. In some cases, revised Proposed values may be posted on this Web site, but the revised ProposedTechnical Support Document for the chemical may be subject to change. (Further information is available through AEGL Process).
