Chemical hazards
Potassium Hydroxyde is used in the electrolyser as the main process liquid (electrolyte). In case of
failures, it can also be present inside or outside connected or nearby devices.
The electrolyte is typically delivered pre-mixed with the electrolyser but is sometimes provided as a
powder to be diluted. For more information on this process, please refer to Appendix II below.
Warning! Refer to the Material Safety Data Sheet (MSDS) of all chemicals
used before handling them. All persons mixing, draining, and handling the
electrolyte must be informed about any potential hazards involved with
these activities.
Attention: Wear appropriate Personal Protective Equipment (PPE). Avoid any
contact with eyes and skin.
If you got in contact with the solution, immediately wash the affected area
and refer to the material safety data sheet of potassium hydroxide supplied
with the electrolyser.
Ensure all material used to store and contain your electrolyte solution is
chemically compatible with it.
In the event of physical contact with the undiluted substance, refer to the material safety data sheet
of potassium hydroxide and follow the instructions below.
First Aid Recommendations
• In the event of skin contact, take off contaminated clothing
immediately. Wash off with soap and plentiful water. Consult a doctor.
• In the event of eye contact, rinse carefully with plentiful water for at
least 15 minutes, and consult a doctor.
If ingested, do not administer anything to people that have fainted. Rinse
mouth with water. Consult a doctor immediately.
