Technical Basis
A review of available sources identified exposure limits for a similar chemical: lithium hydride (CASRN: 7580-67-8, ERPGs, IDLH, TLV-C, TWAs). Data sources were selected according to the hierarchy listed in Table 3.1. The lithium hydride ERPGs were selected as TEELs.
• TEEL-1 = ERPG-1 (lithium hydride, CASRN: 7580-67-8, 2022)
• TEEL-2 = ERPG-2 (lithium hydride, CASRN: 7580-67-8, 2022)
• TEEL-3 = ERPG-3 (lithium hydride, CASRN: 7580-67-8, 2022)
This review generated TEEL-2 and TEEL-1 values consistent with Rev. 29A. The Rev.29A and current source, an ERPG-3, are consistent; the difference in values is due to an update to the published lithium hydride EPRG-3 value in 2022.

PAC values marked with a subscript "A" correspond to 60-minute AEGL values.
PAC values marked with a subscript "E" correspond to ERPG values.
PAC values marked by * are >= 10% lower explosive limit (LEL) but < 50% LEL.
PAC values marked by ** are > 50% LEL but < 100% LEL.
PAC values marked by *** are >= LEL.
