AEGL 3 ** 14,000* 7,200* 2,400 1,600

Lower Explosion Limit (LEL) = 55,000 ppm
* = > 10% LEL; ** = > 50% LEL
AEGL 3 - 10 min = ** 40,000 ppm
For values denoted as * safety consideration against the hazard(s) of explosion(s) must be taken into account
For values denoted as ** extreme safey considerations against the hazard(s) of explosion(s) must be taken into account
Level of Distinct Order Awareness (LOA) = 8.9 ppm

IMPORTANT NOTE: Interim AEGLs are established following review and consideration by the National Advisory Committee for AEGLs (NAC/AEGL) of public comments on Proposed AEGLs. Interim AEGLs are available for use by organizations while awaiting NRC/NAS peer review and publication of Final AEGLs. Changes to Interim values and Technical Support Documents may occur prior to publication of Final AEGL values. In some cases, revised Interim values may be posted on this Web site, but the revised Interim Technical Support Document for the chemical may be subject to change. (Further information is available through AEGL Process).
