7.16 Peroxide Forming Chemicals
Many commonly used chemicals, organic solvents in particular, can form shock, heat, and friction sensitive peroxides upon exposure to oxygen through concentration, evaporation, and distillation.
Compounds that are suspected of having very high peroxide levels because of age, unusual viscosity, discoloration, or crystal formation should be considered extremely dangerous. If you discover a container that meets this description, DO NOT attempt to open or move the container. Make other people working in your area aware of the potential explosion hazard and contact EHS immediately at "askEHS".
You will find extensive information related to peroxide forming chemicals, including a list of peroxide formers, and how to test for peroxides in the Laboratory Safety Manual and Chemical Hygiene Plan.
