Table B: Peroxide-forming chemicals  - CSB | SJU - Biology Department

No chemicals are currently on inventory in the biology department that are classified as level 4 extreme explosives. Use of chemicals that are classified level 4 must have prior approval from the biology safety committee. Peroxides can be formed from some common laboratory chemicals after exposure to air. Peroxides can be violently explosive in concentrated form or as solids. Usually concentrations up to 1% of peroxide do not pose a thermal or shock hazard. Organic peroxides are another class of compounds that present an explosion hazard.
