Section 25504 - Exposure to Air

A person otherwise responsible for an exposure to a listed chemical in air does not "expose" an individual within the meaning of Section 25249.6 of the Act to the extent that the person can show that the listed chemical was contained in air that the person received from the ambient air. Where the source of the listed chemical is in part from the ambient air and in part from other sources, "exposure" does not occur as to that portion of the listed chemical from the ambient air to the extent that the person did not put the listed chemical into the ambient air.
