  ACUTE HAZARDS PREVENTION FIRE FIGHTING
FIRE & EXPLOSION Not combustible. Gives off irritating or toxic fumes (or gases) in a fire.        In case of fire in the surroundings, use appropriate extinguishing media.   

 PREVENT DISPERSION OF DUST!  
  SYMPTOMS ACUTE HAZARDS FIRST AID
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 CLASSIFICATION & 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.

PHYSICAL & CHEMICAL INFORMATION

Physical State; Appearance
PINK HYGROSCOPIC CRYSTALS. 

Physical dangers
 

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

Formula: MnSO4.H2O
Molecular mass: 169.0
Relative density (water = 1): 2.95
Solubility in water, g/100ml: 39.3  


EXPOSURE & HEALTH EFFECTS

Routes of exposure
The substance can be absorbed into the body by inhalation of its aerosol and by ingestion. 

Effects of short-term exposure
 

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


Occupational exposure limits
TLV: (respirable fraction): 0.02 mg/m3, ppm, as TWA; (inhalable fraction): 0.1 mg/m3, ppm, as TWA; A4 (not classifiable as a human carcinogen).
MAK: (as Mn, inhalable fraction): 0.2 mg/m3; (as Mn, respirable fraction): 0.02 mg/m3; peak limitation category: II(8); pregnancy risk group: C.
EU-OEL: 0.2 (inhalable) mg/m3 as TWA; 0.05 (respirable) mg/m3 as TWA
