PHYSICAL & CHEMICAL INFORMATION

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

Physical dangers

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

Formula: Fe₂O₃
Molecular mass: 159.7
Melting point: 1565°C
Density: 5.24 g/cm³
Solubility in water: none

EXPOSURE & HEALTH EFFECTS
Routes of exposure Effects of short-term exposure May cause mechanical irritation.	Inhalation risk A nuisance-causing concentration of airborne particles can be reached quickly when dispersed, especially if powdered. 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.

EXPOSURE & HEALTH EFFECTS

Routes of exposure

Effects of short-term exposure
May cause mechanical irritation.

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

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.

OCCUPATIONAL EXPOSURE LIMITS
TLV: (as Fe): (respirable fraction): 5 mg/m³, as TWA; A4 (not classifiable as a human carcinogen). MAK: carcinogen category: 3

ENVIRONMENT

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.
