  ACUTE HAZARDS PREVENTION FIRE FIGHTING
FIRE & EXPLOSION Not combustible but enhances combustion of other substances. Gives off irritating or toxic fumes (or gases) in a fire.  Risk of fire and explosion on contact with combustible substances or reducing agents.  NO contact with combustible substances.    In case of fire in the surroundings, use appropriate extinguishing media.   

 PREVENT DISPERSION OF DUST! STRICT HYGIENE! IN ALL CASES CONSULT A DOCTOR! 
  SYMPTOMS ACUTE HAZARDS FIRST AID
Inhalation Burning sensation. Cough. Sore throat. Shortness of breath. Laboured breathing. Symptoms may be delayed.  Avoid inhalation of dust. Use local exhaust or breathing protection.  Fresh air. Half-upright position. Artificial respiration may be needed. Refer immediately for medical attention. 
Skin Redness. Skin burns. Pain.  Protective gloves. Protective clothing.  Wear protective gloves when administering first aid. 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 burns.  Wear face shield or eye protection in combination with breathing protection.  Rinse with plenty of water for several minutes (remove contact lenses if easily possible). Refer immediately for medical attention. 
Ingestion Burning sensation. Abdominal pain. Diarrhoea. Nausea. Vomiting. Shock or collapse.  Do not eat, drink, or smoke during work.  Rinse mouth. If within a few minutes after ingestion, one small glass of water may be given to drink. Do NOT induce vomiting. Refer immediately for medical attention.

PHYSICAL & CHEMICAL INFORMATION

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. 

Formula: KMnO4
Molecular mass: 158
Decomposes at 240°C
Density: 2.7 g/cm³
Solubility in water, g/100ml at 20°C: 6.4 (moderate)
Vapour pressure at 20°C: negligible
Octanol/water partition coefficient as log Pow: 1.73 (calculated) 


EXPOSURE & HEALTH EFFECTS

Routes of exposure
Serious local effects by all routes of exposure. 

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, but only after initial corrosive effects on eyes and/or airways have become manifest. The effects may be delayed. Medical observation is indicated. 

Inhalation risk
A harmful concentration of airborne particles can be reached quickly when dispersed, especially if powdered. 

Effects of long-term or repeated exposure
The substance may have effects on the lungs. This may result in bronchitis and pneumonia. Animal tests show that this substance possibly causes toxicity to human reproduction or development. 


Occupational exposure limits
TLV: (as Mn): 0,2 mg/m3, ppm, as TWA.
MAK: (as Mn, inhalable fraction): 0.2 mg/m3; (as Mn, respirable fraction): 0.02 mg/m3; peak limitation category: II(1); pregnancy risk group: C; (DFG 2016).
EU-OEL: New EU SCOEL recommendation available (SUM/127/2011); as Mn, inhalable fraction: 0.2 mg/m3 as TWA; as Mn, as respirable fraction:0.05 mg/m3 as TWA 

ENVIRONMENT
The substance is very toxic to aquatic organisms. 

NOTES
Rinse contaminated clothing with plenty of water because of fire hazard.
