Choosing Hazardous substance storage cabinets

When you first look at the vast range of hazardous storage cabinets you may be forgiven for asking why so many and what’s the difference. On the face of it all the cabinets are COSHH compliant i.e they meet the basic requirements of the Control of Substances Hazardous to Health regulations so why not go for a basic COSHH cabinet rather than the substance specific options for flammables, pesticides and acid and alkali’s?

The first question to answer is what specific types and how much of these hazardous substances do you have to secure to comply with COSHH legislation. Secondly you need to be aware of the dangers of storing incompatible substances in the same cabinet. Acids do not go with alkali’s and flammables should be segregated from all other hazards. Aggressive and toxic chemicals such as systemic agricultural pesticides are a direct hazard to health and are subject to additional controls, some requiring licences to store and use. In extreme cases, particularly involving bio hazards specialist cabinets to BS EN14470-1 may be required.

The substance specific cabinets offer more protection and are not just different coloured versions of the same cabinet. Flammable storage cabinets have deep spill tray shelves and deep sumps with welded seams to prevent leakage. Rebated doors prevent accidental exposure to naked flames. An Acid and Alkali cabinet has similar features but are made from Zintec steel for added corrosion resistance. Pesticide Storage cabinets also feature additional louvred ventilation to prevent the build-up of toxic fumes and have galvanised steel rather than powder coated shelves. Of course all the cabinets have hazard specific corrosion resistant powder coated finish, quality key locking for access control and security and hazard specific warning labels.

For those storing hazardous substances on site the different colour coded finishes provide a further benefit in an emergency – particularly a fire emergency – as irrespective of the warning label the fire and rescue services can quickly identify at a distance the type and location of any hazardous materials present. Storing different types of hazardous substances in the same anonymous Cabinet is a hazard in itself so assess the risks carefully and make the right safety choices.
