The vapors of any volatle liquid are the most dangerous,(explosive) in high concentrations. Methanol is quick to vaporize at relatively low temperatures.
No open head processors, only use sealed and pressure relief processors.
Methanol liquid is easily absorbed thru the skin, avoid contact or inhalation of vapors.
Naoh or Koh is a caustic high Alkaline will burn on contact with bare skin.
Treat the WHOLE PROCESS for what it is ... a "CHEMICAL REACTION WITH DANGEROUS CHEMICALS"
