Instruction Manual
 All personnel involved in the mixing, use, storage, transportation,
and disposal of the electrolytes or its components, should be
thoroughly trained in the precautions for handling perchloric acid.
 Great importance must be attached to precautions against
inhalation of vapours of the solution or its components, against
skin contact, mixing and overheating, and concerning storage
and disposal methods.
 Place the solvent/water mixture in a water bath with temperature
control. Carefully add the perchloric acid to the solvent/water
mixture, stir continuously.
 The mixing must take place in a ventilated chemical fume hood
designed for perchloric acid use.
 The operator(s) must use the listed protective clothing or
devices: full face shield or splash goggles, rubber gloves and lab
coat or coveralls.
 Avoid the use of any combustible or carbonaceous containers,
reaction vessels, spill pans, storage shelves, or materials of this
type when dealing with the acid.
 Do not permit any acid to crystallise on bottle necks, caps, or
anywhere else.
 Store in secure, cool, and ventilated area with metal, glass, or
ceramic spill catch pan.
 Store away from other chemicals, combustible and organic
materials.
 Do not, under any circumstances, permit solutions to dry out.
 60% perchloric acid is a strongly corrosive and oxidising product.
Heating may cause an explosion and contact with combustible
material may cause fire.
 Fire fighting should be done from a protected location.
Extinguish with water spray only. Do not use dry chemicals or
carbon dioxide.
 Do not produce anhydrous perchloric acid, either from its salts or
from aqueous solutions, e.g. by heating with high boiling acids or
dehydrating agents, such as sulphuric acid or phosphorous
pentoxide. In addition to spontaneous explosion, the anhydrous
acid explodes instantaneously on contact with oxidizable organic
materials.
 The use or storage of perchloric acid should be limited to
quantities less than 500 g per hood.
