Technical Basis
A review of available sources was able to identify exposure limits for this chemical. The AEGLs for this chemical were used as the basis of the TEELs.
TEEL-1= AEGL-1 (60-minute; xylene, CASRN: 1330-20-7)
TEEL-2= AEGL-2
TEEL-3= AEGL-3
This review resulted in values that are consistent with Rev. 29A.
TEEL-1= AEGL-1 (60-minute; xylene, CASRN: 1330-20-7)
TEEL-2= AEGL-2
TEEL-3= AEGL-3
This review resulted in values that are consistent with Rev. 29A.
