TYPES OF HAZARD/ EXPOSURE ACUTE HAZARDS/ SYMPTOMS PREVENTION FIRST AID/ FIRE FIGHTING

FIRE Not combustible. Gives off irritating or toxic fumes (or gases) in a fire. In case of fire in the surroundings: all extinguishing agents allowed. 

### EXPLOSION

EXPOSURE PREVENT DISPERSION OF DUST!

•INHALATION Cough. Shortness of breath. Sore throat. Local exhaust. Fresh air, rest.

•SKIN Redness. Protective gloves. Rinse and then wash skin with water and soap.

•EYES Redness. Safety spectacles. First rinse with plenty of water for several minutes (remove contact lenses if easily possible), then take to a doctor.

•INGESTION Convulsions. Headache. Nausea. Vomiting. Do not eat, drink, or smoke during work. Give plenty of water to drink. Rest.



### SPILLAGE DISPOSAL STORAGE PACKAGING & LABELLING
Sweep spilled substance into containers; if appropr iate, moisten first to prevent dusting. Wash away remainder with plenty of water. Separated from incompatible materials, (see chemical dangers).

A PHYSICAL STATE; APPEARANCE: WHITE CRYSTALS , WITH CHARACTERISTIC ODOUR.

PHYSICAL DANGERS:

CHEMICAL DANGERS: The substance decompos es on heating above melting point produci ng toxic gases. Reacts violently with strong oxidants, nitrites, inorganic chlorides, chlo rites and perchlorates causing fire and e xplosion hazard.

OCCUPATIONAL EXPOSURE LIMITS: TLV not established. ROUTES OF EXPOSURE: The substance can be abso rbed into the body by inhalation of its aerosol and by ingestion.

INHALATION RISK:Evaporation at 20°C is negligible; a nuisancecausing concentrat ion of airborne particles can, however, be reached quickly if powdered.

EFFECTS OF SHORT-TERM EXPOSURE: The substance irritates th e eyes, the skin and the respiratory tract.

EFFECTS OF LONG-TERM OR REPEATED EXPOSURE: Repeated or prolonged contact with skin may cause dermatitis.

PHYSICAL PROPERTIES Melting point: 132.7-135°C Density: 1.32 Solubility in water: miscible Octanol/water partition co efficient as log Pow: -3.00 to -1.54

ENVIRONMENTAL DATA

N O T E S Temperature of decomposition unknown in literature.
