TYPES OF HAZARD
/ EXPOSURE
ACUTE HAZARDS / SYMPTOMS PREVENTION FIRST AID / FIRE-FIGHTING
FIRE Combustible. Gives off irritating or toxic fumes (or gases) in a fire.  NO open flames. NO contact with flammables.  Use water spray, foam, powder, carbon dioxide. 
EXPLOSION      
 
EXPOSURE   PREVENT DISPERSION OF DUST!   
Inhalation   Avoid inhalation of dust. Use breathing protection.  Fresh air, rest. Refer for medical attention. 
Skin Redness. Pain.  Protective gloves. Protective clothing.  Remove contaminated clothes. Rinse skin with plenty of water or shower. 
Eyes Redness. Pain.  Wear safety goggles or eye protection in combination with breathing protection if powder.  Rinse with plenty of water for several minutes (remove contact lenses if easily possible). 
Ingestion   Do not eat, drink, or smoke during work.  Rinse mouth. Do NOT induce vomiting. 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. 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 strong oxidants and incompatible materials. Keep in a well-ventilated room. Store only in original container. Store in an area without drain or sewer access. 

IMPORTANT DATA
Physical State; Appearance
ODOURLESS COLOURLESS-TO-WHITE GREYISH-WHITE SOLID IN VARIOUS FORMS. 

Physical dangers
Dust explosion possible if in powder or granular form, mixed with air. 

Chemical dangers
Decomposes on heating and on burning. This produces toxic fumes including hydrogen chloride (see ICSC 0163) and nitrogen oxides. Reacts with strong oxidants. Corrosive to iron and steel. 

Occupational exposure limits
TLV: 1mg/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 ingestion and by inhalation of its aerosol. 

Inhalation risk
Evaporation at 20°C is negligible; a harmful concentration of airborne particles can, however, be reached quickly on spraying or when dispersed, especially if powdered. 

Effects of short-term exposure
 

Effects of long-term or repeated exposure
Repeated or prolonged contact may cause skin sensitization. The substance may have effects on the kidneys and liver. The substance may have effects on the spleen. This may result in siderosis. This substance is possibly carcinogenic to humans. 


PHYSICAL PROPERTIES ENVIRONMENTAL DATA
Boiling point at 101.3kPa: >400°C
Melting point: 40°C
Density: 1.1 g/cm³
Solubility in water, g/100ml at 25°C: 0.02 (very poor)
Flash point: 137°C c.c.
Octanol/water partition coefficient as log Pow: 3.5
Relative vapour density (air = 1): 9.3
Vapour pressure, Pa at °C: (negligible) 
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.
