TYPES OF
HAZARD /
EXPOSURE
ACUTE HAZARDS / SYMPTOMS      PREVENTION      FIRST AID / FIRE FIGHTING
FIRE Not combustible but enhances combustion of other substances. Gives off irritating or toxic fumes (or gases) in a fire.  NO contact with flammables.  In case of fire in the surroundings, use appropriate extinguishing media. 
EXPLOSION Risk of fire and explosion on contact with combustible substances or reducing agents.     
 
EXPOSURE   PREVENT DISPERSION OF DUST! STRICT HYGIENE!   
Inhalation Burning sensation. Cough. Sore throat. Shortness of breath. Laboured breathing. Symptoms may be delayed. See Notes.  Avoid inhalation of dust. Use local exhaust or breathing protection.  Fresh air, rest. Half-upright position. Artificial respiration may be needed. Refer for medical attention. 
Skin Redness. Skin burns. Pain.  Protective gloves. Protective clothing.  First rinse with plenty of water for at least 15 minutes, then remove contaminated clothes and rinse again. Refer for medical attention . 
Eyes Redness. Pain. Severe deep burns.  Wear face shield or eye protection in combination with breathing protection.  First rinse with plenty of water for several minutes (remove contact lenses if easily possible), then refer for medical attention. 
Ingestion Burning sensation. Abdominal pain. Diarrhoea. Nausea. Vomiting. Shock or collapse.  Do not eat, drink, or smoke during work.  Rinse mouth. Give one or two glasses of water to drink. Do NOT induce vomiting. Refer for medical attention .

IMPORTANT DATA
Physical State; Appearance
DARK PURPLE CRYSTALS. 

Physical dangers
 

Chemical dangers
Decomposes on heating. This produces toxic gases and irritating fumes. The substance is a strong oxidant. It reacts with combustible and reducing materials. This generates fire and explosion hazard. Reacts violently with powdered metals. This generates fire hazard. 

Occupational exposure limits
TLV (as Mn): 0.2mg/m³ as TWA; (ACGIH 2003). 

Routes of exposure
The substance can be absorbed into the body by inhalation of dust 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
The substance is corrosive to the eyes, skin and respiratory tract. Corrosive on ingestion. Inhalation of dust may cause lung oedema. See Notes. The effects may be delayed. Medical observation is indicated. 

Effects of long-term or repeated exposure
The substance may have effects on the lungs. This may result in bronchitis and pneumonia. 


PHYSICAL PROPERTIES ENVIRONMENTAL DATA
Decomposes at 240°C
Density: 2.7 g/cm³
Solubility in water, g/100ml at 20°C: 6.4
Vapour pressure at 20°C: negligible 
The substance is very toxic to aquatic organisms. 

NOTES
Rinse contaminated clothes (fire hazard) with plenty of water.
The symptoms of lung oedema often do not become manifest until a few hours have passed and they are aggravated by physical effort.
Rest and medical observation is therefore essential.
Card has been partly updated in October 2005.
See section Occupational Exposure Limits.
