Excerpts from Documentation for IDLHs |
Concentrations of 12,000 ppm caused immediate eye irritation in volunteers and 5 minutes at 6,500 ppm resulted in eye irritation, headache, and vertigo [Sayers and Yant 1929]. Workers exposed intermittently to concentrations up to 1,500 ppm complained of no systematic symptoms over a period of several years [Watrous 1947]. |
