TYPES OF
HAZARD /
EXPOSURE
ACUTE HAZARDS / SYMPTOMS      PREVENTION      FIRST AID / FIRE FIGHTING
FIRE Not combustible.    In case of fire in the surroundings, use appropriate extinguishing media. 
EXPLOSION      
 
EXPOSURE      
Inhalation Cough.  Avoid inhalation of dust.  Fresh air, rest. 
Skin      
Eyes Redness.  Wear safety goggles.  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.   

SPILLAGE DISPOSAL
PACKAGING & LABELLING
Personal protection: particulate filter respirator adapted to the airborne concentration of the substance. Sweep spilled substance into covered containers.

IMPORTANT DATA
Physical State; Appearance
REDDISH BROWN-TO-BLACK CRYSTALS OR POWDER. 

Physical dangers
 

Chemical dangers
Reacts with carbon monoxide. This generates explosion hazard. 

Occupational exposure limits
TLV (as Fe): 5mg/m³ as TWA; A4 (not classifiable as a human carcinogen); (ACGIH 2004). 

Routes of exposure
 

Inhalation risk
A nuisance-causing concentration of airborne particles can be reached quickly when dispersed, especially if powdered. 

Effects of short-term exposure
May cause mechanical irritation. 

Effects of long-term or repeated exposure
Repeated or prolonged inhalation of dust particles may cause effects on the lungs. This may result in siderosis; a benign condition. 


PHYSICAL PROPERTIES ENVIRONMENTAL DATA
Melting point: 1565°C
Density: 5.24 g/cm³
Solubility in water: none 
 

NOTES
There is a UN number associated with ferric oxide but this relates to iron oxide, spent, or iron sponge, spent obtained from coal gas purification which is spontaneously combustible.
