PEROXIDES AND PEROXIDE FORMING COMPOUNDS
Peroxides, in contact with inorganic obalt and copper compounds, iron or iron compounds, acetone, metalc oxide salt, and acids or bases can react with rapid, uncontrolled decomposition of peroxides leading to fires and explosions (3) Peroxides may form on the surface of finely divided alkali metals and their amides and readily form
Example – Peroxide Forming Chemicals
The peroxides formed in these reactions are extremely shock and heat sensitive The liquid chemicals in this group should be tested for peroxides and discarded within 6 months of opening Acrylic acid Chlorotrifluoroethylene Vinyl acetate Acrylonitrile Methyl methacrylate Vinylacetylene (gas)
Chemicals That Form Peroxides: Handling and Storage
Chemicals That Form Peroxides: Handling and Storage Peroxy compounds are examples of chemicals which present special problems In the laboratory because they can be violently reactive or explosive Their handling deserves careful attention Inorganic Peroxides Inorganic peroxy compounds are generally stable as such, but in contact with

Peroxide-Forming Chemicals (PFCs)
isopropyl alcohol, can also form peroxides if best practices are not followed Identifying Peroxide Formers According to Prudent Practices (Chapter 4 D 3 2 Azos, Peroxides, and Peroxidizables), any organic compound with a weak C–H bond is at risk for forming peroxides depending on the conditions or contaminants the chemical is exposed to
ORGANIC PEROXIDES CHEMICAL HAZARDS & RISK MINIMIZATION
the solution Do not store organic peroxides which are diluted with water at temperatures below 0°C (32°F) to avoid separating out the pure organic peroxide Organic peroxides can also be strong oxidizing agents Combustible materials contaminated with most organic peroxides can catch firevery easily , even spontaneously, and burn very intensely
Safety of organic peroxides - Nouryon
put peroxides in closed metal contain-ers or glass bottles without having installed appropriate venting devices Contamination Contamination constitutes a hazard, because many chemicals seriously reduce the decomposition temperature (SADT) of organic peroxides Notorious examples are metal salts, amines, acids, bases and construction materials such
Peroxide Formers and Other Potential Explosives SOP
Peroxides are also often shock sensitive compounds that can explode if subjected to mechanical shock, intense light, rapid changes in temperature, heat, friction, or in some cases, by spontaneous reaction Chemicals that can potentially form peroxides (peroxidizables) are categorized into three classes (A-C) defined below
