TYPES OF
HAZARD /
EXPOSURE
ACUTE HAZARDS / SYMPTOMS      PREVENTION      FIRST AID / FIRE FIGHTING
FIRE Combustible under specific conditions. Liquid formulations containing organic solvents may be flammable. Gives off irritating or toxic fumes (or gases) in a fire.  NO open flames.  Use water spray, foam, powder, carbon dioxide. 
EXPLOSION Risk of fire and explosion if formulations contain flammable/explosive solvents.     
 
EXPOSURE   PREVENT DISPERSION OF DUST!   
Inhalation   Use ventilation (not if powder).  Fresh air, rest. 
Skin   Protective gloves.  Rinse and then wash skin with water and soap. 
Eyes Redness. Pain.  Wear safety spectacles.  Rinse with plenty of water (remove contact lenses if easily possible). Refer for medical attention. 
Ingestion   Do not eat, drink, or smoke during work. Wash hands before eating.  Rinse mouth. Refer for medical attention . 

SPILLAGE DISPOSAL
PACKAGING & LABELLING
Personal protection: particulate filter respirator adapted to the airborne concentration of the substance. Do NOT let this chemical enter the environment. Sweep spilled substance into covered containers. If appropriate, moisten first to prevent dusting. Carefully collect remainder. Then store and dispose of according to local regulations.  Do not transport with food and feedstuffs.

EMERGENCY RESPONSE SAFE STORAGE
  Provision to contain effluent from fire extinguishing. Separated from food and feedstuffs. Store in an area without drain or sewer access. 

IMPORTANT DATA
Physical State; Appearance
COLOURLESS CRYSTALS. 

Physical dangers
No data. 

Chemical dangers
Decomposes on heating. This produces toxic fumes including hydrogen chloride and nitrogen oxides. 

Occupational exposure limits
TLV: 5mg/m³ as TWA; A4 (not classifiable as a human carcinogen); (ACGIH 2009).
MAK (inhalable fraction): 2 mg/m³; Peak limitation category: II(8); (DFG 2009). 

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

Inhalation risk
A harmful concentration of airborne particles can be reached quickly when dispersed. 

Effects of short-term exposure
The substance is severely irritating to the eyes. 

Effects of long-term or repeated exposure
The substance may have effects on the liver. This may result in tissue lesions. 


PHYSICAL PROPERTIES ENVIRONMENTAL DATA
Boiling point: No boiling point at normal pressure; decomposes on heating
See Notes.
Melting point: 173-177°C
Relative density (water = 1): 1.2
Solubility in water, g/100ml at 25°C: (none)
Vapour pressure, Pa at 20°C: (negligible)
Octanol/water partition coefficient as log Pow: 2.34  
The substance is toxic to aquatic organisms. This substance does enter the environment under normal use. Great care, however, should be taken to avoid any additional release, for example through inappropriate disposal. 

NOTES
Temperature of decomposition is unknown in the literature.
Carrier solvents used in commercial formulations may change physical and toxicological properties.
If the substance is formulated with solvents also consult the ICSCs of these materials.
