  ACUTE HAZARDS PREVENTION FIRE FIGHTING
FIRE & EXPLOSION Gives off irritating or toxic fumes (or gases) in a fire.        In case of fire in the surroundings, use appropriate extinguishing media.   

 STRICT HYGIENE! AVOID EXPOSURE OF ADOLESCENTS AND CHILDREN! IN ALL CASES CONSULT A DOCTOR! See Notes. 
  SYMPTOMS ACUTE HAZARDS FIRST AID
Inhalation See Ingestion.  Use ventilation (not if powder), local exhaust or breathing protection.  Fresh air, rest. Refer for medical attention. 
Skin MAY BE ABSORBED! See Ingestion.  Protective gloves. Protective clothing.  Remove contaminated clothes. Rinse skin with plenty of water or shower. Refer for medical attention . 
Eyes   Wear face shield or eye protection in combination with breathing protection if powder.  First rinse with plenty of water for several minutes (remove contact lenses if easily possible), then refer for medical attention. 
Ingestion Dizziness. Drowsiness. Nausea. Shock or collapse. Spontaneous bleeding from various sites. See Notes.  Do not eat, drink, or smoke during work. Wash hands before eating.  Rinse mouth. Induce vomiting (ONLY IN CONSCIOUS PERSONS!). Refer for medical attention . See Notes.

EXPOSURE & HEALTH EFFECTS

Routes of exposure
The substance can be absorbed into the body by inhalation, through the skin and by ingestion. 

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

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

Effects of long-term or repeated exposure
 


Occupational exposure limits
 

ENVIRONMENT
The substance is very toxic to aquatic organisms. This substance may be hazardous to the environment. Special attention should be given to terrestrial organisms. Bioaccumulation of this chemical may occur in 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
The symptoms of bleeding do not become manifest until days later.
Specific treatment is necessary in case of poisoning with this substance; the appropriate means with instructions must be available.
Insufficient data are available on the effect of this substance on human health, therefore utmost care must be taken.
Do NOT take working clothes home.
