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 flammable substances.	In case of fire in the surroundings: use appropriate extinguishing media.
EXPLOSION	Risk of fire and explosion on contact with heat orcombustible substances.		In case of fire: cool drums, etc., by spraying with water but avoid contact of the substance with water.

EXPOSURE
•INHALATION	Cough. Shortness of breath.	Local exhaust or breathing protection.	Fresh air, rest.
•SKIN		Protective gloves.	First rinse with plenty of water, then remove contaminated clothes and rinse again.
•EYES	Redness. Pain.	Safety goggles.	First rinse with plenty of water for several minutes (remove contact lenses if easily possible), then take to a doctor.
•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.

PHYSICAL STATE; APPEARANCE:
WHITE CRYSTALLINE POWDER

PHYSICAL DANGERS:

CHEMICAL DANGERS:
The substance decomposes on warming above 60°C producing toxic fumes including sodium oxide and on contact with water producing boric acid and hydrogen peroxide. The substance is a strong oxidant and reacts with combustible and reducing materials. The solution in water is a weak base.

OCCUPATIONAL EXPOSURE LIMITS:
TLV not established.
MAK 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 the respiratory tract .

EFFECTS OF LONG-TERM OR REPEATED EXPOSURE:

PHYSICAL
PROPERTIES

Melting point (decomposes): about 60-65.5°C

Solubility in water, g/100 ml at 20°C: 2.3

ENVIRONMENTAL
DATA

The substance is harmful to aquatic organisms.

N O T E S

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