TYPES OF
HAZARD /
EXPOSURE
ACUTE HAZARDS / SYMPTOMS      PREVENTION      FIRST AID / FIRE FIGHTING
FIRE Combustible.  NO open flames.  Use water spray, powder, foam, carbon dioxide. 
EXPLOSION      
 
EXPOSURE   PREVENT DISPERSION OF DUST! PREVENT GENERATION OF MISTS!   
Inhalation   Use local exhaust or breathing protection.  Fresh air, rest. 
Skin   Protective gloves. Protective clothing.  Remove contaminated clothes. Rinse skin with plenty of water or shower. 
Eyes Redness. Pain. Severe deep burns.  Wear safety goggles or eye protection in combination with breathing protection.  First rinse with plenty of water for several minutes (remove contact lenses if easily possible), then refer for medical attention. 
Ingestion Abdominal pain. Burning sensation.  Do not eat, drink, or smoke during work.  Rinse mouth. Give one or two glasses of water to drink. Refer for medical attention . Rest. 

SPILLAGE DISPOSAL
PACKAGING & LABELLING
Personal protection: filter respirator for organic gases and particulates adapted to the airborne concentration of the substance. Sweep spilled substance into covered sealable containers. If appropriate, moisten first to prevent dusting. Then store and dispose of according to local regulations.   
EC Classification
Symbol: Xn; R: 22-38-41-48/22; S: (2)-26-36/37/39-46 
UN Classification
 
GHS Classification
 

EMERGENCY RESPONSE SAFE STORAGE
NFPA Code: H1; F1; R0.  Separated from strong oxidants and acids. Dry. 

IMPORTANT DATA
Physical State; Appearance
WHITE CRYSTALS OR COLOURLESS VISCOUS HYGROSCOPIC LIQUID WITH CHARACTERISTIC ODOUR. 

Physical dangers
The vapour is heavier than air. 

Chemical dangers
Decomposes on burning. This produces toxic fumes. The solution in water is a medium strong base. Reacts violently with strong oxidants and strong acids. Attacks copper, zinc, aluminium and their alloys. 

Occupational exposure limits
MAK: Carcinogen category: 3A; Skin absorption (H); Sensitization of skin (SH); (DFG 2002). 

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

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. 

Effects of short-term exposure
The substance is corrosive to the eyes. 

Effects of long-term or repeated exposure
Repeated or prolonged contact may cause skin sensitization. The substance may have effects on the liver and kidneys.
