Excerpts from Documentation for IDLHs
Human data: Volunteers exposed to 70,000 ppm for 3 minutes experienced lightheadedness and disturbances in balance and ability to respond to visual stimulus [Reinhardt and Reinke 1972]; 3 hours to 70,000 ppm caused decrements in mental performance tests [Harrison et al. 1982]. Exposure to 50,000 ppm for 20 to 25 minutes caused drowsiness, light­headedness, and a slight effect on judgment [Hine et al. 1968]. Three volunteers experienced mild nose and throat discomfort after 28 minutes of exposure to 71,000 ppm [Stewart et al. 1978]. Others reported that a 30­minute exposure at 43,000 to 45,000 ppm caused dizziness, light­headedness, euphoria, and disturbances in equilibrium and coordination [Stewart et al. 1978].
Lethal Concentration
LC50 (rat) = 84,000 ppm/15 min
