Technical Basis
A review of available sources was unable to identify exposure limits for this chemical, but toxicity data was available. The rat 4-hr LC50 toxicity data was selected as the TEEL-3 basis and scaled to a 60-minute equivalent with the ten Berge equation (Section 3.3.4.) TEEL-2 and TEEL-1 values were calculated from this TEEL-3, in accordance with guidelines in the handbook (see Table 3.5.)
TEEL-1 = TEEL-2 /11
TEEL-2 = TEEL-3 / 6
TEEL-3 = TEEL-3 estimated from rat 4-hr LC50 (90 mg/m3)
This review generated values that are more conservative than those reported in Rev. 29A. In Rev. 29A, the TEEL-3 basis was a rat oral LD50, the current recommendation is a more preferred toxicity exposure route (see Table 3.1.)
