EXPOSURE
ACUTE HAZARDS / SYMPTOMS      PREVENTION      FIRST AID / FIRE FIGHTING
FIRE Combustible.  NO open flames.  Use water spray, powder, foam, carbon dioxide. 
EXPLOSION      
 
EXPOSURE   STRICT HYGIENE!   
Inhalation   Use local exhaust or breathing protection.  Fresh air, rest. 
Skin   Protective gloves.  Remove contaminated clothes. Rinse and then wash skin with water and soap. 
Eyes   Wear safety spectacles.  First rinse with plenty of water for several minutes (remove contact lenses if easily possible), then refer for medical attention. 
Ingestion Spontaneous bleeding from various sites.  Do not eat, drink, or smoke during work. Wash hands before eating.  Give a slurry of activated charcoal in water to drink. Refer for medical attention .

Physical dangers
 

Chemical dangers
 

Occupational exposure limits
TLV: 0.1mg/m³ as TWA; (ACGIH 2004). 

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

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

Effects of short-term exposure
The substance may cause effects on the blood. This may result in haemorrhage. The effects may be delayed. Medical observation is indicated. 

Effects of long-term or repeated exposure
 


PHYSICAL PROPERTIES ENVIRONMENTAL DATA
Decomposes
Melting point: 108-110°C
Density: 1.06 g/cm³
Solubility in water at 25°C: none
Vapour pressure at 25°C: negligible 
The substance is very toxic to aquatic organisms. This substance may be hazardous to the environment. Special attention should be given to birds and mammals. 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 unknown in literature.
Depending on the degree of exposure, periodic medical examination is suggested.
The symptoms of bleeding do not become manifest until a few hours or even a few days have passed.
Specific treatment is necessary in case of poisoning with this substance; the appropriate means with instructions must be available.
