If the heat evolved in a reaction is not dissipated, the reaction can increase until an explosion results. Organic peroxides are a special class of compounds that have unusual stability problems that make them among the most hazardous substances normally handled in laboratories. Peroxide formation has been responsible for many serious explosions. Under normal storage conditions, some chemicals can form and accumulate peroxides which explode violently when shocked or heated. When possible, purchase peroxidizable compounds with inhibitors incorporated into them.
Store containers away from heat sources and light.
Store in a cool and dry location. Never return excess chemicals to the original container. Small amounts of impurities may be introduced into the container that may cause a fire or explosion. The quantity of reactives should be limited to the minimum amount required. Dispose of all reactive chemicals whenever they are no longer required for current research.
