Justification for type of information:
Waiver is proposed for this test based on Column 2, Specific Rules for Adaption from Column 1 for section 8.5, which requires that an oral acute study and an acute study by one other route be conducted. The choice of the second route based on the nature of the substance and the likely route of human exposure. An acute oral and an acute dermal study have been conducted so the acute inhalation is not required.
