TYPES OF
HAZARD /
EXPOSURE
ACUTE HAZARDS / SYMPTOMS      PREVENTION      FIRST AID / FIRE FIGHTING
FIRE Not combustible but enhances combustion of other substances. Gives off irritating or toxic fumes (or gases) in a fire.  NO contact with flammables.  In case of fire in the surroundings, use appropriate extinguishing media. 
EXPLOSION Risk of fire and explosion on contact with heat or combustible substances.    In case of fire: keep drums, etc., cool by spraying with water. NO direct contact with water. 
 
EXPOSURE      
Inhalation Cough. Shortness of breath.  Use local exhaust or breathing protection.  Fresh air, rest. 
Skin   Protective gloves.  First rinse with plenty of water for at least 15 minutes, then remove contaminated clothes and rinse again. 
Eyes Redness. Pain.  Wear safety goggles.  First rinse with plenty of water for several minutes (remove contact lenses if easily possible), then refer for medical attention. 
Ingestion Nausea. Vomiting. Diarrhoea.  Do not eat, drink, or smoke during work.  Rinse mouth. Give a slurry of activated charcoal in water to drink. Rest. Refer for medical attention .

IMPORTANT DATA
Physical State; Appearance
WHITE CRYSTALLINE POWDER. 

Physical dangers
 

Chemical dangers
Decomposes above 60°C . This produces toxic fumes including sodium oxide. Decomposes on contact with water. This produces boric acid and hydrogen peroxide. The substance is a strong oxidant. It reacts with combustible and reducing materials. The solution in water is a weak base. 

Occupational exposure limits
TLV (NOT-ESTABLISHED):. 

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

Inhalation risk
Evaporation at 20°C is negligible; a harmful concentration of airborne particles can, however, be reached quickly when dispersed, especially if powdered. 

Effects of short-term exposure
The substance is irritating to the eyes and respiratory tract. 

Effects of long-term or repeated exposure
 


PHYSICAL PROPERTIES ENVIRONMENTAL DATA
Decomposes at ~60-65.5°C
Solubility in water, g/100ml at 20°C: 2.3  
The substance is harmful to aquatic organisms. 

NOTES
Rinse contaminated clothes (fire hazard) with plenty of water.
