| If a mixture has
been tested as a whole to determine its hazards, the results shall be used. |
If a mixture has
not been tested as a whole:
- The mixture is assumed to present health
hazards of
the components that comprise 1% or greater of
the mixture (0.1% for carcinogens)
- Evaluation may be performed using any
available scientifically
valid data.
|
If any component
present in the mixture in concentrations of less than 1% (or less than 0.1% for
carcinogens) could, upon release, exceed the concentrations established in OSHA's permissible
exposure limits (PELs), or the American Conference of Governmental Industrial
Hygienist's (ACGIH) Threshold
Limit Values (TLVs), or present a health hazard, the mixture shall be assumed to
present the same hazard. Mixture Evaluation Hazard Determination |
