    Organic peroxides

Use H5.2 when the material presents organic peroxides.

Organic waste with an O-O bond that can decompose violently and heat itself. A federal H characteristic code.

Is Federal H5.2 hazardous waste?

Not from this code alone. Federal H5.2 is one classification component for describing hazardous waste or hazardous recyclable material. It records a constituent or characteristic. Federal status depends on all the evidence and on the definitions and exclusions in SOR/2021-25.

On federally regulated international shipments, the applicant enters the waste classification in the waste-line details of the federal notification in CNMTS. Also apply the movement rules and exclusions.

What does Federal H5.2 cover?

This characteristic covers an organic substance or waste with the oxygen-oxygen structure of a peroxide. Its heat instability can set off self-accelerating decomposition that gives off heat. Not every organic compound that contains oxygen is an organic peroxide.

Official wording
Any organic substance or waste containing the bivalent-0-0-structure that may undergo exothermic self-accelerating decomposition due to its thermal instability. (Organic peroxides)

Is organic peroxide waste always Federal H5.2?

CodeWhen it fits
H5.2Peroxide structure and heat instability can cause self-accelerating decomposition that releases heat.

Decide from where the material came from, how it was used, what is in it and what the tests show. A shared chemical or process word isn't enough, because the full wording and any federal exclusion still apply.
