Storage Requirements

Oxidising Acids
All oxidising acids are highly reactive with most substances and with each other. Examples : Nitric, sulfuric, perchloric, phosphoric and chromic acids

Primary Storage Concern : To prevent contact and reaction with each other and other substances and corrosive action on surfaces. Each oxidising acid must be double-contained, i.e., the primary container must be kept inside.

Recommended Facilities/Measures : Safety cabinet

Compatible Storage Groups
Oxidising acids must be double-contained and should be segregated in their own compartment in a safety cabinet. When quantities are small (e.g 1 or 2 bottles) they do not warrant a separate compartment. Small quantities may be double-contained and stored with organic and mineral acids. Store oxidising acids on bottom shelf below organic and mineral acids.

Organic And Mineral Acids
Example : Acetic, nutyric, formic, glacial acetic hydrochloric, mercaptoproprionic, proprionic, trifluoroacetic acids.

Primary Storage concern : To prevent contact and reaction with bases and oxidising acids and corrosive action on surfaces.

Recommended Facilities/Measures : Safety cabinet

Compatible Storage Group : Small amounts of double-contained oxidising acids can be stored in the same compartment with organic acids if the oxidising acids are stored on the bottom shelf.

Exception : Acetic anhydride and trichloroacetic anhydride are corrosive. These acids are very reactive with acids and should not be stored in this group. It is better to store these with organic compounds listed as Non-volatile Liquid Poisons, such as acrylamide solution; diethylprocarbonate, diisopropyl fluorophosphates, uncured epoxy resins, ethidium bromide, triethanolamine
