Excerpts from Documentation for IDLHs
Human data: A very short exposure (<30 seconds) to a concentration estimated to be less than 100 ppm has resulted in nausea and vomiting within 5 minutes; other persons in the same room also complained of the nauseating odor but did not become ill [Cornish 1965].
