Excerpts from Documentation for IDLHs
Human data: A 30minute exposure to 4.8 mg/m3 has been reported to produce respiratory distress [Ferry 1974]. Exposure to 80 mg/m3 has caused nausea and coughing and 120 mg/m3 for 2 minutes has caused nose and upper respiratory system irritation [Cullumbine 1957].
