TYPES OF
HAZARD /
EXPOSURE 		ACUTE HAZARDS / SYMPTOMS      PREVENTION      FIRST AID / FIRE FIGHTING
FIRE Not combustible. Gives off irritating or toxic fumes (or gases) in a fire.    In case of fire in the surroundings, use appropriate extinguishing media. 
EXPLOSION      
 
EXPOSURE   PREVENT DISPERSION OF DUST!   
Inhalation Cough. Laboured breathing. Shortness of breath. Sore throat.  Use local exhaust or breathing protection.  Fresh air, rest. Half-upright position. Refer for medical attention. 
Skin   Protective gloves.   
Eyes Redness.  Wear safety spectacles or eye protection in combination with breathing protection if powder.  Rinse with plenty of water for several minutes (remove contact lenses if easily possible). 
Ingestion Sore throat.  Do not eat, drink, or smoke during work.  Rinse mouth. 

SPILLAGE DISPOSAL
 		PACKAGING & LABELLING
Personal protection: particulate filter respirator adapted to the airborne concentration of the substance. Sweep spilled substance into covered containers. If appropriate, moisten first to prevent dusting. Wash away remainder with plenty of water.

IMPORTANT DATA
Physical State; Appearance
PINK HYGROSCOPIC CRYSTALS. 

Physical dangers
 

Chemical dangers
Decomposes on heating. This produces sulfur oxides and manganese oxides. 

Occupational exposure limits
TLV (as Mn): 0.2mg/m³ as TWA; (ACGIH 2006).
MAK (inhalable fraction): 0.5 mg/m³; 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, especially if powdered. 

Effects of short-term exposure
 

Effects of long-term or repeated exposure
The substance may have effects on the central nervous system. 


PHYSICAL PROPERTIES ENVIRONMENTAL DATA
Relative density (water = 1): 2.95
Solubility in water, g/100ml: 39.3   		 

NOTES
Card has been partially updated in October 2006.
