2.5.1 Perchloric acid
If you are working with Struers electrolytes marked with the prefix A, you must mix a certain amount
of perchloric acid into the electrolyte solution.
CAUTION
Always request and read the Safety Data Sheet for each electrolyte before you start
working with it.
To find the Safety Data Sheet for the components in question, see: www.struers.com.
CAUTION
Fire and explosion hazards
• 60% perchloric acid is a very corrosive and oxidizing product. Heating it can
cause an explosion, and contact with combustible materials can cause fire.
• Fire fighting must be carried out from a protected location. Use extinguishing
media as specified in the Safety Data Sheet.
Training
CAUTION
All persons involved in mixing, using, storing, transporting and disposing of
electrolytes must be trained in how to handle perchloric acid when carrying out these
tasks.
• Do not inhale any vapor from the solution or its components.
• Avoid skin contact.
Mixing perchloric acid into the electrolyte solution

of perchloric acid into the electrolyte solution.
WARNING
Always wear a full-face shield or splash goggles, rubber gloves and a laboratory coat
or coveralls when you are working with perchloric acid.
WARNING
Make sure that you are mixing the solvent in a chemical-fume hood designed for
perchloric acid use.
WARNING
Do not use combustible or carbonaceous containers, reaction vessels, spill pans,
storage shelves or similar materials when you work with perchloric acid.
