  ACUTE HAZARDS PREVENTION FIRE FIGHTING
FIRE & EXPLOSION Combustible.  Finely dispersed particles form explosive mixtures in air.  NO open flames.    Use special powder, dry sand. NO other agents. Water may be ineffective.   

 PREVENT DISPERSION OF DUST!  
  SYMPTOMS PREVENTION FIRST AID
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.  Rinse with plenty of water (remove contact lenses if easily possible). 
Ingestion Abdominal pain. Nausea. Vomiting.  Do not eat, drink, or smoke during work.  Rinse mouth. Refer for medical attention .

PHYSICAL & CHEMICAL INFORMATION

Physical State; Appearance
SOLID IN VARIOUS FORMS. 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.

Octanol/water partition coefficient as log Pow: -0.57 (calculated) 


EXPOSURE & HEALTH EFFECTS

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

Effects of short-term exposure
Inhalation of fumes may cause metal fume fever. See Notes. 

Inhalation risk
A harmful concentration of airborne particles can be reached quickly when dispersed. 

Effects of long-term or repeated exposure
Repeated or prolonged contact may cause skin sensitization. Ingestion may cause effects on the liver. 


OCCUPATIONAL EXPOSURE LIMITS
TLV: (fume, as Cu): 0.2 mg/m3, as TWA.
TLV: (dust and mists, as Cu): 1 mg/m3, as TWA.
MAK: (respirable fraction): 0.01 mg/m3; peak limitation category: II(2); pregnancy risk group: C 

ENVIRONMENT
The substance is very toxic to aquatic organisms. Bioaccumulation of this chemical may occur along the food chain. 

NOTES
The symptoms of metal fume fever do not become manifest until a few hours have passed.
UN 3089 refers to METAL POWDERS, FLAMMABLE, (n.o.s.)
