Physical dangers
 

Chemical dangers
Reacts with strong oxidants, cyanides and sulfides. Reacts violently with aluminium, zinc and tin. This generates fire and explosion hazard. The solution in water is a medium strong acid. 

Occupational exposure limits
TLV (NOT-ESTABLISHED):. 

Routes of exposure
The substance can be absorbed into the body by inhalation and by ingestion. 

Inhalation risk
A harmful concentration of airborne particles can be reached quickly on spraying or when dispersed, especially if powdered. 

Effects of short-term exposure
The substance is corrosive to the skin and eyes. The substance is irritating to the respiratory tract. Corrosive on ingestion. This may result in kidney failure. 

Effects of long-term or repeated exposure
Repeated or prolonged contact with skin may cause dermatitis.
