Potassium Hydroxide
HAZARD ALERT: Skin contact causes severe blisters; strongly corrosive as a solid and as a solution; very harmful if swallowed; extremely dangerous to eyes. LD50 273 mg/kg. TLV-C 2 mg/m3.
  SPECIAL HAZARD ALERT: Wear appropriate face and body protection when making solutions; potassium hydroxide gener- ates large amounts of heat while dissolving. You might consider immersing your solution-making vessel in an ice bath. The ice bath will better enable you to control the solution temperature. Stir continuously.

A Laboratory Never!
NEVER grind a strong oxidizing agent (like potassium chlorate) together with a strong reducing agent. The reaction that may result is highly exothermic. We repeat, NEVER GRIND potassium chlorate with anything! If mixing is required, grind the substances separately and then gently mix using a glass stirring rod.
