| Comments |
Severe damage to the cornea has been reported after occupational exposure. Experimental animals exposed repeatedly to 30 ppm develop respiratory disease with bronchiolar inflammation. [ACGIH] Its severe corneal toxicity is delayed by several hours, and workers have little or no immediate eye symptoms. [HSDB] Has potential to cause pulmonary edema after high inhalation exposure; May have effects on liver and kidneys; [ICSC] |
