105 Mass. Reg. 650.010
Current through Register 1524, June 21, 2024
For a mixture of substances, the determination of whether the mixture is a "hazardous substance" should be based on the physical, chemical, and pharmacological characteristics of the mixture. A mixture of substances may therefore be less hazardous or more hazardous than its components because of synergistic or antagonistic reactions. It may not be possible to reach a fully satisfactory decision concerning the toxic, irritant, corrosive, flammable, sensitizing, or pressure-generating properties or a substance from what is known about its components or ingredients. The mixture itself should be tested.
