| Comments |
Inhalation studies in animals show that 4 hour exposures to 10 ppm are lethal; 4 hour exposures to 5 ppm cause pulmonary edema; and 4 hour exposures to 1 ppm are without apparent effect. [ACGIH] Decomposes into selenium and hydrogen fluoride on contact with moisture; [ATSDR Medical Management] Liquid may cause frostbite; A corrosive substance that can cause pulmonary edema; [ICSC] See "Selenium and compounds" and "Hydrogen fluoride." |
