Technical Basis
A review of available sources identified short term exposure limits (REL, PEL, TLV) for this chemical. Data sources were selected according to the hierarchy listed in Table 3.1. The TLV-STEL was selected as the TEEL-1 basis. TEEL-2 and TEEL-3 values were derived according to Table 3.5.
• TEEL-1 = TLV-STEL (0.3 mg/m3; skin)
• TEEL-2 = TEEL-1 x 11
• TEEL-3 = TEEL-2 x 6
This review generated TEEL values that are consistent with Rev. 29A.
• TEEL-1 = TLV-STEL (0.3 mg/m3; skin)
• TEEL-2 = TEEL-1 x 11
• TEEL-3 = TEEL-2 x 6
This review generated TEEL values that are consistent with Rev. 29A.
