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 perchloric acid precautions.
 Great importance must be attached to precautions against inhalation of
vapors of the solution or its components, against skin contact, mixing
and overheating, and concerning storage and disposal methods.
 Add the perchloric acid to the solvent/water mixture slowly, stirring
continuously, in a water bath with temperature control.
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 crystallize on bottle necks, caps, or anywhere
else.
Store in secure, ventilated area with metal, glass, or ceramic spill catch

pan.
 Store away from other chemicals, combustible materials, and organics.
 Do not permit solutions to dry out under any circumstances.
 60% perchloric acid is classified as a Material that will not burn, but
caution should be taken against their coming in contact with organic
material which could cause an explosion.
 Fire fighting should be done from a protected location. Extinguish with
water spray.
 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 sulfuric acid or phosphorous pentoxide. In
addition to spontaneous explosion, the anhydrous acid explodes
instantaneously in contact with oxidizable organic materials.
The use or storage of perchloric acid should be limited to quantities less

than 500 g per hood.
 Follow local regulations when residues are to be disposed of.
 Dilution and/or neutralization are the normally recommended methods
of disposal for the electrolyte.
