Time-sensitive chemicals may become hazardous on prolonged or incorrect storage for a variety of reasons e.g., chloroform may produce highly toxic phosgene gas or hydrogen peroxide and concentrated formic acid may generate gas pressure in the bottle. The mechanisms, however, are completely different than organic peroxide formers, and peroxides may not even be involved, but despite the deficiency in the nomenclature, these materials are commonly included in the general class of “peroxide formers”.
