Class 5.1 / 5.2 – Oxidizing substances and organic peroxides
Class 5 is divided into two division as follow:
Division 5.1 - Oxidizing Substances
- Which, in themselves are not necessarily combustible, but may generally cause or contribute to the combustion of other material by yielding oxygen. Such substances may be contained in an article.
Division 5.2 – Organic Peroxides
- Is made up of organic substances which contain the bivalent structure -O-O- and may be considered derivatives of hydrogen peroxide in which one or both of the hydrogen atoms have been replaced by organic radicals.
- Are thermally unstable substances which may undergo exothermic, self-accelerating decomposition.
- In addition, they may have one or more of the following properties:
i. Be liable to explosive decomposition
ii. Burn rapidly
iii. Be sensitive to impact or friction
iv. React dangerously with other substances
