| Comments |
Asthma reported in a solderer and a locksmith; [Malo] At a concentration of 0.4 mg/m3, ZnCl2 caused no respiratory irritation; at 4.8 mg/m3 for 30 minutes, transient respiratory irritation occurred. Higher concentrations after industrial accidents have been associated with toxic pneumonitis. [ACGIH] Zinc chloride is corrosive to the eyes, skin, and respiratory tract; [ICSC] |
