POTASSIUM OXIDE

ICSC: 0769

IMPORTANT DATA

PHYSICAL STATE; APPEARANCE:
GREY, HYGROSCOPIC, CRYSTALLINE POWDER.

CHEMICAL DANGERS:
The solution in water is a strong base, it reacts violently with acid and is corrosive. Reacts violently with water producing potassium hydroxide. Attacks many metals in presence of water.

OCCUPATIONAL EXPOSURE LIMITS:
TLV not established.
MAK not established.

ROUTES OF EXPOSURE:
Serious local effects by all routes of exposure.

INHALATION RISK:
A harmful concentration of airborne particles can be reached quickly when dispersed

EFFECTS OF SHORT-TERM EXPOSURE:
The substance is corrosive to the eyes, the skin and the respiratory tract. Corrosive on ingestion. Inhalation of aerosol may cause lung oedema (see Notes). Medical observation is indicated.

PHYSICAL PROPERTIES

Melting point (decomposes): 350°C
Density: 2.3 g/cmł
Solubility in water: reaction

ENVIRONMENTAL DATA

NOTES

Reacts violently with fire extinguishing agents such as 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 are therefore essential. Immediate administration of an appropriate inhalation therapy by a doctor or a person authorized by him/her, should be considered. See Potassium hydroxide ICSC 0357.
