Comments
Liquid causes first degree burns on short exposure; [CHRIS] Corrosive to skin; [Quick CPC] Diisopropylamine is a severe pulmonary irritant in acute and chronic animal studies. At concentrations of 25 to 50 ppm, workers have experienced transient corneal injury, nausea, and headache. [ACGIH] A corrosive substance that causes lacrimation and may cause lung edema after inhalation of high concentrations; [ICSC]
Skin Designation (ACGIH)
Yes
