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      
 
EXPOSURE   AVOID ALL CONTACT!   
Inhalation   Use ventilation (not if powder).  Fresh air, rest. Seek medical attention if you feel unwell. 
Skin Redness.  Protective gloves. Protective clothing.  Remove contaminated clothes. Rinse and then wash skin with water and soap. Refer for medical attention . 
Eyes Redness.  Wear safety spectacles or face shield.  Rinse with plenty of water (remove contact lenses if easily possible). Refer for medical attention. 
Ingestion Vomiting. Diarrhoea.  Do not eat, drink, or smoke during work. Wash hands before eating.  Rinse mouth. Seek medical attention if you feel unwell. 

SPILLAGE DISPOSAL

IMPORTANT DATA
Physical State; Appearance
WHITE CRYSTALS. 

Physical dangers
 

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

Occupational exposure limits
TLV (inhalable fraction): 5mg/m³ as TWA; (SEN); A3 (confirmed animal carcinogen with unknown relevance to humans); (ACGIH 2009).
MAK (not established):. 

Routes of exposure
The substance can be absorbed into the body by inhalation of its aerosol. 

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

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

Effects of long-term or repeated exposure
Repeated or prolonged contact with skin may cause dermatitis. Repeated or prolonged contact may cause skin sensitization. 


PHYSICAL PROPERTIES ENVIRONMENTAL DATA
Melting point: No melting point; decomposes at 178°C
Relative density (water = 1): 1.74
Solubility in water, g/100ml at 25°C: (none)
Octanol/water partition coefficient as log Pow: 2.35  
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
Carrier solvents used in commercial formulations may change physical and toxicological properties.
Do NOT take working clothes home.
