TYPES OF
HAZARD /
EXPOSURE
ACUTE HAZARDS / SYMPTOMS      PREVENTION      FIRST AID / FIRE FIGHTING
FIRE Combustible. Gives off irritating or toxic fumes (or gases) in a fire.  NO open flames.  Use water in large amounts. 
EXPLOSION Finely dispersed particles form explosive mixtures in air.  PREVENT DISPERSION OF DUST. Prevent build-up of electrostatic charges (e.g., by grounding).   
 
EXPOSURE      
Inhalation Cough. Sore throat.  Use local exhaust.  Fresh air, rest. 
Skin   Protective gloves.  Rinse skin with plenty of water or shower. 
Eyes Redness. Pain.  Wear safety spectacles.  Rinse with plenty of water (remove contact lenses if easily possible). 
Ingestion   Do not eat, drink, or smoke during work.  Rinse mouth. Give one or two glasses of water to drink. 

SPILLAGE DISPOSAL
PACKAGING & LABELLING
Personal protection: particulate filter respirator adapted to the airborne concentration of the substance. Sweep spilled substance into covered containers. If appropriate, moisten first to prevent dusting. Wash away remainder with plenty of water.   
EC Classification
 
UN Classification
 
GHS Classification
 

EMERGENCY RESPONSE SAFE STORAGE
  Dry. Well closed. 

IMPORTANT DATA
Physical State; Appearance
WHITE HYGROSCOPIC CRYSTALLINE POWDER WITH CHARACTERISTIC ODOUR. 

Physical dangers
Dust explosion possible if in powder or granular form, mixed with air. 

Chemical dangers
Decomposes on heating. This produces toxic and corrosive fumes of sodium oxide. The solution in water is a weak base. 

Occupational exposure limits
TLV: 10mg/m³ as TWA; (ACGIH 2011).
MAK (not established):. 

Routes of exposure
See Notes. 

Inhalation risk
Evaporation at 20°C is negligible; a nuisance-causing concentration of airborne particles can, however, be reached quickly when dispersed. 

Effects of short-term exposure
See Notes. 

Effects of long-term or repeated exposure
See Notes. 


PHYSICAL PROPERTIES ENVIRONMENTAL DATA
Solubility in water, g/100ml: 100 (good)
Melting point: 210°C
Flash point: >250°C o.c. 
 

NOTES
Health effects of exposure to the substance have been investigated, but none has been found.
