| Excerpts from Documentation for IDLHs |
Human data: Workers exposed to zinc concentrations between 320 to 580 mg/m3 for 1�3 hours have experienced nausea on the job, and chills, shortness of breath, and severe chest pains 2 to 12 hours later [Hammond 1944]. Two men exposed to about 600 mg/m3 for 10.5 to 12 minutes experienced headaches, chills, and fever with cough and a decrease in vital capacity which persisted for 15 hours after exposure [Sturgis and Thompson 1927]. |
