Stable
Conditions Contributing to Instability None
Incompatibility
KOH = Avoid contact with strong acids or Acetic Acid = Avoid contact with
strong
bases
Hazardous Decomposition Products
KOH = None or Acetic Acid = Emits toxic fumes when heated
Conditions to Avoid
KOH = None or Acetic Acid = Heat

Steps if material is released
Sensor is packaged in a sealed plastic bag, check the sensor inside for electrolyte
leakage. If the sensor leaks inside the plastic bag or inside an analyzer sensor
housing, do not remove it without rubber or latex gloves and safety glasses and a
source of water. Flush or wipe all surfaces repeatedly with water or wet paper
towel
(fresh
each
time).
Disposal
In accordance w ith federal, state and local regulations.
Health Hazard Information
Primary Route(s) of Entry
