labelling of organic peroxidesBy the very nature of these substances, it is critical that all labelling of organic peroxides is checked at the time of delivery. You should make sure the labels remain in a good state so that they are legible at all times. The area(s) where the organic peroxide is going to be stored or used must likewise be suitably marked.

The following information on labelling of organic peroxides is taken directly from “The storage and handling of organic peroxides” – Guidance Note CS21 issued by the Health and Safety Executive.

MARKING AND LABELLING

Sites storing more than 25 tonnes of dangerous substances, as defined by the CHIP Regulations (see reference 13), should be marked in accordance with The Dangerous Substances (Notification and Marking of Sites) Regulations 1990 (see reference 18).

Storerooms, cupboards and bins must be marked to indicate their contents. Where direct marking is not reasonably practicable the marking should be displayed close to the store. ‘No smoking’ signs should also be displayed.

Individual containers should be clearly marked to indicate their contents, principal hazard and basic safety precautions. In most cases this will be dealt with by the Carriage of Dangerous Goods (Classification, Packaging and Labelling) and Use of Transportable Pressure Receptacles Regulations 1996 (see reference 19). Organic peroxides which are designated as presenting a significant hazard from explosion must bear a subsidiary explosion risk label when kept or conveyed in accordance with paragraphs 9 to 11 of Schedule 3 of the Classification and Labelling of Explosives Regulations 1983 (SI 1983/1140).
