Perchloric acid may react violently with many chemicals, including acetic anhydride, alcohol, reducing agents, and many metals. &#; In wet digestions with perchloric acid, treat the sample first with nitric acid to destroy easily oxidizable matter. &#; Do not distill perchloric acid in a vacuum, because the unstable anhydride may be

Perchloric acid is a colorless, fuming, oily liquid. When cold, its properties are that of a strong acid; but when hot, the concentrated acid acts as a strong oxidizing agent. Aqueous perchloric acid can cause violent explosions if misused, or when used in concentrations greater than

There are many documented accidents resulting from perchloric acid. Hazard Control: Perchloric acid is destructive to human tissue as well as very reactive. The lab should be properly equipped and certain guidelines followed to ensure safety.

LABORATORY SAFETY GUIDELINE. Perchloric Acid [CAS No. ] Perchloric acid is an incredibly strong inorganic acid that poses many hazards. All individuals at Harvard who use perchloric acid must review this document. Users of anhydrous perchloric acid

&#; Always transfer perchloric acid over a sink or other suitable containment in order to catch any spills and afford a ready means of cleanup and disposal. &#; Perform all operations on chemically resistant surfaces. Avoid contact with cellulose materials such as wood, paper and cotton. Perchloric acid may become concentrated and cause a fire or

//&#;&#;Perchloric Acid Revision Date -Jan General Advice Show this safety data sheet to the doctor in attendance. Immediate medical attention is required. Eye Contact Rinse immediately with plenty of water, also under the eyelids, for at least minutes. Immediate medical attention is required. Skin Contact Wash off immediately with plenty of water for at least minutes.

Do not use perchloric acid > %; anhydrous perchloric acid (> % concentration) is particularly hazardous and its use is strictly forbidden. Do not work near sparking sources and open flames. Do NOT heat perchloric acid in fume hoods. Do not distill perchloric acid in a vacuum. Do not store perchloric acid near heat sources.

The quantities of perchloric acid kept in storage should be kept to a minimum. Perchloric acid should be stored in its original container within compatible secondary containment, preferably glass or porcelain. Glass trays should be wiped periodically. Perchloric acid should be separate from other chemicals, but may be stored with other inorganic
