The TLV of the mixture (T
Mixture
) is found by using the following formula where T
1
, T
2
, T
3
, . . . are the individual contaminant
TLVs and C
1
, C
2
, C
3
, . . . are the individual contaminant concentrations:
Only use these equations if the contaminants present are actually mixed. Some substances do not mix and may be present
separately, for example, in pockets or at different levels. In that case, the lowest TLV of the substances present must be used
to determine the appropriate respirator category for protection against all contaminants present.
See MSA’s
Response® Respirator Guide
