Division 6.4 For any exposure scenario, the risk to humans and the environment can be considered to be adequately controlled, throughout the lifecycle of the substance that results from manufacture or identified uses, if:X1

the exposure levels estimated in Section 6.2 do not exceed the appropriate DNEL or the PNEC, as determined in Sections 1 and 3, respectively, and,

the likelihood and severity of an event occurring due to the physicochemical properties of the substance as determined in Section 2 is negligible.
