ANNEX 9: Chemicals that can form Explosive Peroxide

Some organic and inorganic compounds can react with oxygen in the air to form potentially explosive peroxides. Peroxide formation is accelerated when the substances are exposed to light and heat. Chemicals that can form dangerous peroxides are divided in 3 categories

Category 1 chemicals: Some organic and inorganic compounds can react with oxygen in the air to form potentially explosive peroxides. Peroxide formation is accelerated when the substances are exposed to light and heat. Chemicals that can form dangerous peroxides are divided in 3 categories

Category 2 chemicals: Chemicals which become a peroxide hazard if concentrated, such as through distillation or evaporation.

Category 3 chemicals: Chemicals which become a peroxide hazard if concentrated, such as through distillation or evaporation.

At the Sars Centre we presently only possess category 2 chemicals.

Bottles containing peroxide-forming substances must be labelled “PEROXIDE-FORMING”; print the label below and attach to the container.
