TYPES OF
HAZARD /
EXPOSURE
ACUTE HAZARDS / SYMPTOMS      PREVENTION      FIRST AID / FIRE FIGHTING
FIRE Combustible.  NO open flames.  Use special powder, dry sand. NO other agents. 
EXPLOSION      
 
EXPOSURE   PREVENT DISPERSION OF DUST!   
Inhalation Cough. Headache. Shortness of breath. Sore throat.  Use local exhaust or breathing protection.  Fresh air, rest. Refer for medical attention. 
Skin Redness.  Protective gloves.  Remove contaminated clothes. Rinse and then wash skin with water and soap. 
Eyes Redness. Pain.  Wear safety goggles.  First rinse with plenty of water for several minutes (remove contact lenses if easily possible), then refer for medical attention. 
Ingestion Abdominal pain. Nausea. Vomiting.  Do not eat, drink, or smoke during work.  Rinse mouth. Refer for medical attention . 

SPILLAGE DISPOSAL
PACKAGING & LABELLING
Personal protection: particulate filter respirator adapted to the airborne concentration of the substance. Sweep spilled substance into covered containers. Carefully collect remainder. Then store and dispose of according to local regulations.

IMPORTANT DATA
Physical State; Appearance
RED POWDER. TURNS GREEN ON EXPOSURE TO MOIST AIR. 

Physical dangers
No data. 

Chemical dangers
Mixtures with acetylenic compounds, ethylene oxide and azides are shock-sensitive. Reacts with strong oxidants such as chlorates, bromates and iodates. This generates explosion hazard. 

Occupational exposure limits
MAK (inhalable fraction): 0.1 mg/m³; Peak limitation category: II(2); Pregnancy risk group: C; (DFG 2007). 

Routes of exposure
The substance can be absorbed into the body by inhalation 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
Inhalation of fume may cause metal fume fever. See Notes. 

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


PHYSICAL PROPERTIES ENVIRONMENTAL DATA
Boiling point: 2595°C
Melting point: 1083°C
Relative density (water = 1): 8.9
Solubility in water: none 
 

NOTES
The symptoms of metal fume fever do not become manifest until several hours.
Card has been partially updated in January 2008: see Occupational Exposure Limits.
