Safe Handling of Mineral Acids

A mineral acid (or inorganic acid) is defined as a water-soluble acid derived from inorganic minerals by chemical reaction as opposed to organic acids (e.g. acetic acid, formic acid). Examples of mineral acids include: • Boric acid (CAS No.10043-35-3) • Chromic acid (CAS No.1333-82-0) • Hydrochloric acid (CAS No.7647-01-0) • Hydrofluoric acid (CAS No. 7664-39-3) • Nitric acid (CAS No. 7697-37-2) • Perchloric acid (CAS No. 7601-90-3) • Phosphoric acid (CAS No.7664-38-2) • Sulfuric acid (CAS No.7664-93-9) Mineral acids are commonly found in research laboratories and their corrosive nature makes them a significant safety risk. Since they are important reagents in the research laboratory and often do not have substitutes, it is important that they are handled properly and with care. Some acids are even shock sensitive and under certain conditions may cause explosions (i.e., salts of perchloric acid).

Many animal experiments rely on final data collection time points that are gathered from the harvesting and testing of organs and tissues. The use of appropriate methods for the collection of organs and tissues can impact the quality of the samples and the analysis of the data that is gleaned for the testing of the tissues. The method of euthanasia of the animal can also impact the quality of the samples. This manuscript will outline proper necropsy techniques for rats.
