MANGANESE SULPHATE MONOHYDRATE ICSC: 0290
IMPORTANT DATA
PHYSICAL STATE; APPEARANCE:
PINK HYGROSCOPIC CRYSTALS.

CHEMICAL DANGERS:
The substance decomposes on heating producing sulfur oxides and manganese oxides.

OCCUPATIONAL EXPOSURE LIMITS:
TLV: 0.2 mg/m as TWA; (ACGIH 2004).
MAK: (as Mn) (Inhalable fraction) 0.5 mg/m; Pregnancy risk group: C; (DFG 2004).
ROUTES OF EXPOSURE:
The substance can be absorbed into the body by inhalation of the dust and by ingestion.

INHALATION RISK:
Evaporation at 20C is negligible; a harmful concentration of airborne particles can, however, be reached quickly when dispersed, especially if powdered.

EFFECTS OF LONG-TERM OR REPEATED EXPOSURE:
Lungs may be affected by inhalation of high concentrations resulting in decreased functions. The substance may have effects on the central nervous system.
PHYSICAL PROPERTIES
Relative density (water = 1): 2.95
Solubility in water, g/100 ml: 39.3

NOTES
Card has been partly updated in October 2005. See section Occupational Exposure Limits.
