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 PACKAGING & LABELLING
Sweep spilled substance into containers; if appropriate, moisten first to prevent dusting. Wash away remainder with plenty of water.


EMERGENCY RESPONSE STORAGE

Separated from incompatible materials, (see chemical dangers).

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

CHEMICAL DANGERS:
The substance decomposes on heating above melting point producing toxic gases. Reacts violently with strong oxidants, nitrites, inorganic chlorides, chlorites and perchlorates causing fire and explosion hazard.

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

INHALATION RISK:
Evaporation at 20°C is negligible; a nuisance-causing concentration of airborne particles can, however, be reached quickly if powdered.

EFFECTS OF SHORT-TERM EXPOSURE:
The substance irritates the 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 coefficient as log Pow: -3.00 to -1.54

ENVIRONMENTAL DATA


NOTES
Temperature of decomposition unknown in literature.
