Physical dangers
 

Chemical dangers
Decomposes on burning. This produces toxic fumes including ammonia and nitrogen oxides. The substance is a strong base. It reacts violently with acid and is corrosive. Reacts with oxidants and chlorinated hydrocarbons. 

Occupational exposure limits
TLV not established.
MAK (not established):. 

Routes of exposure
Serious local effects by all routes of exposure. 

Inhalation risk
A harmful contamination of the air will not or will only very slowly be reached on evaporation of this substance at 20°C; on spraying or dispersing, however, much faster. 

Effects of short-term exposure
The substance is corrosive to the eyes, skin and respiratory tract. Corrosive on ingestion. Inhalation of mist may cause severe swelling of the throat. 

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