MANGANESE OXIDE

ICSC: 1398

IMPORTANT DATA

PHYSICAL STATE; APPEARANCE:
BROWN TO BLACK CRYSTALLINE POWDER

OCCUPATIONAL EXPOSURE LIMITS:
TLV: as Mn 0.2 mg/mł as TWA; (ACGIH 2006).
MAK: as Mn (Inhalable fraction) 0.5 mg/mł; Pregnancy risk group: C; (DFG 2005).

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:
May cause mechanical irritation.

EFFECTS OF LONG-TERM OR REPEATED EXPOSURE:
The substance may have effects on the lungs and central nervous system , resulting in increased susceptibility to bronchitis, pneumonitis and neurologic, neuropsychiatric disorders (manganism). Animal tests show that this substance possibly causes toxicity to human reproduction or development.

PHYSICAL PROPERTIES

Melting point: 1564°C
Density: 4.8 g/cmł
Solubility in water, g/100 ml: none

ENVIRONMENTAL DATA

NOTES

Depending on the degree of exposure, periodic medical examination is suggested. Occurs in nature as the mineral Hausmannite.
