Technical Basis
A review of available sources identified TWAs (PEL, REL, TLV), and an AEGL-2, and AEGL-3 for this chemical. The AEGLs were selected as the TEEL-2 and TEEL-3 due to their priority among the emergency exposure limits (Section 1). The most preferred TWA, the TLV-TWA, was selected as the TEEL-1 basis and was derived according to Table 3.5.
• TEEL-1 = TLV-TWA (0.005 ppm) x 3
• TEEL-2 = AEGL-2
• TEEL-3 = AEGL-3
This review generated TEEL-1 values inconsistent with Rev. 29A. In Rev. 29A the TEEL-1 was derived from the AEGL-2; however, this review used an exposure limit, a TLV-TWA, as the TEEL-1 basis. The TEEL-2 and TEEL-3 methodology and values remain consistent.
