Excerpts from Documentation for IDLHs

Very little toxicological data are available concerning the effects produced by exposure to tert­butyl chromate. Because AIHA [1965] reported that the severity of the health hazard is low for acute exposure to chromic acid, by analogy it is assumed that the hazard is also low for acute exposure to tert­butyl chromate. Therefore, the chosen IDLH is based on an analogy with chromic acid and chromates, which has an IDLH of 30 mg/m3 (as CrO3).
