Abstract

As the hydrogen economy receives attention, much research has been conducted on water electrolysis that can produce green hydrogen. After investigating the various risk factors that exist in the alkaline water electrolysis process through hazard and operability study and job safety analysis, which are risk assessments, measures to ensure safety were prepared and made into a manual. Possible risks that could occur during various emergency stop situations and operations were identified, and leakage of potassium hydroxide (KOH) and hydrogen used as electrolyte appeared to be the main risk. If you utilize a risk assessment for the relevant equipment when writing a manual, you will be able to prepare work procedures that substantially reduce risk factors.
