HAZARD /
EXPOSURE
ACUTE HAZARDS / SYMPTOMS      PREVENTION      FIRST AID / FIRE FIGHTING
FIRE Not combustible. Gives off irritating or toxic fumes (or gases) in a fire.    In case of fire in the surroundings, use appropriate extinguishing media. 
EXPLOSION      
 
EXPOSURE   AVOID ALL CONTACT!   
Inhalation Cough.  Use closed system or ventilation.  Fresh air, rest. Refer for medical attention. 
Skin Redness. Pain.  Protective gloves. Protective clothing.  Remove contaminated clothes. Rinse and then wash skin with water and soap. 
Eyes Redness.  Wear safety goggles or eye protection in combination with breathing protection.  First rinse with plenty of water for several minutes (remove contact lenses if easily possible), then refer for medical attention. 
Ingestion   Do not eat, drink, or smoke during work.  Rinse mouth. Refer for medical attention .

IMPORTANT DATA
Physical State; Appearance
GREEN-TO-BLACK CRYSTALLINE POWDER. 

Physical dangers
 

Chemical dangers
Reacts violently with iodine and hydrogen sulfide. This generates fire and explosion hazard. 

Occupational exposure limits
TLV: 0.2mg/m³ as TWA; A1 (confirmed human carcinogen); (ACGIH 2004).
MAK: Carcinogen category: 1; Sensitization of respiratory tract and skin (SAH); (DFG 2004). 

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

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

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

Effects of long-term or repeated exposure
Repeated or prolonged contact may cause skin sensitization. Repeated or prolonged inhalation may cause asthma. The substance may have effects on the lungs. This substance is carcinogenic to humans. 


PHYSICAL PROPERTIES ENVIRONMENTAL DATA
Melting point: 1984°C
Density: 6.7 g/cm³
Solubility in water: none 
The substance is harmful to aquatic organisms. 

NOTES
Anyone who has shown symptoms of asthma due to this substance should avoid all further contact with this substance.
The symptoms of asthma often do not become manifest until a few hours have passed and they are aggravated by physical effort.
Rest and medical observation are therefore essential.
Do NOT take working clothes home.
Card has been partly updated in October 2004.
