Methanol, Potassium Salt: HSNO Approval: HSR007896 Approved with controls

Rapidly and exothermically reacts with tissue water forming potassium hydroxide (responsible for corrosivity) and methanol; Not likely to cause skin sensitization or be carcinogenic; [OECD SIDS: Methanolates - 2006] Reacts violently with water; Self-heating, may catch fire; Causes burns; Inhalation may cause corrosive injuries to upper respiratory tract and lungs; [Alfa Aesar MSDS] See Methyl alcohol. See Potassium hydroxide. See Sodium methylate.

Heating may cause violent combustion or explosion. Reacts violently with water. This produces flammable methanol and corrosive potassium hydroxide. The substance may ignite spontaneously on contact with moist air. The substance is a strong reducing agent. It reacts violently with oxidants. The substance is a strong base. It reacts violently with acid and is corrosive. Attacks many metals. This produces flammable/explosive gas (hydrogen - see ICSC 0001).
