TYPES OF
HAZARD /
EXPOSURE
ACUTE HAZARDS / SYMPTOMS      PREVENTION      FIRST AID / FIRE FIGHTING
FIRE Highly flammable. Many reactions may cause fire or explosion. Gives off irritating or toxic fumes (or gases) in a fire.  NO contact with water, acids or halogens. NO open flames, NO sparks and NO smoking.  Use special powder, dry sand. NO other agents. 
EXPLOSION Risk of fire and explosion on contact with acids, halogens or water.    Combat fire from a sheltered position. 
 
EXPOSURE      
Inhalation Cough. Sore throat. Burning sensation.  Use closed system or ventilation.  Fresh air, rest. Half-upright position. Artificial respiration may be needed. Refer for medical attention. 
Skin Pain. Blisters. Serious skin burns.  Protective gloves. Protective clothing.  Remove contaminated clothes. Rinse skin with plenty of water or shower. Refer for medical attention . 
Eyes Severe deep burns. Loss of vision.  Wear face shield.  First rinse with plenty of water for several minutes (remove contact lenses if easily possible), then refer for medical attention. 
Ingestion Burning sensation. Shock or collapse.  Do not eat, drink, or smoke during work.  Rinse mouth. Refer for medical attention .

IMPORTANT DATA
Physical State; Appearance
WHITE-TO-GREY LUMPS. 

Physical dangers
 

Chemical dangers
Reacts violently with water. This generates fire and explosion hazard. Decomposes rapidly under the influence of air and moisture. This produces flammable/explosive gas (hydrogen - see ICSC 0001). 

Occupational exposure limits
TLV (NOT-ESTABLISHED):. 

Routes of exposure
Serious by all routes of exposure. 

Inhalation risk
 

Effects of short-term exposure
See ICSC 0357 (potassium hydroxide). 

Effects of long-term or repeated exposure
 


PHYSICAL PROPERTIES ENVIRONMENTAL DATA
Boiling point: 765.5°C
Melting point: 63.2°C
Density: 0.856 g/cm³
Solubility in water: reaction
Vapour pressure at 20°C: negligible 
 

NOTES
Potassium is always kept under mineral oil.
Reacts violently with fire extinguishing agents such as water and carbon dioxide.
