Organic Peroxide Storage- Firevault

Organic Peroxide Storage – Stainless Steel

Typically, chemical stores would be fabricated from mild steel which is then over-painted with a 2-part or 3-part industrial paint system. Standard units would also have exposed galvanized grid decking onto which the pallets would rest – these are unpainted and therefore expose the mild steel to the chemicals stored – in this case Organic Peroxide. Read on for our solution to your organic peroxide storage needs.

When designing an organic peroxide store a Grade 316 stainless steel finish is required, in all locations that could come into contact with the Peroxide. This includes the storage areas, the spillage retention bunds and the fire water retention tank.

The relevant HSE Guidance reference is called: –

 CS21 – The Storage and Handling of Organic Peroxides. – Download it here

This is written, specifically to cover the

“… handling and storage of organic peroxides at customer or user sites.”

It clearly details the hazards associated with exposing such chemicals to mild/carbon steel: –

“… commercially available organic peroxides are capable of self heating and runaway decomposition. Initiation is by heating or contamination with, for example, transition metal compounds (particularly those of vanadium, chromium, manganese, iron and cobalt) amines, strong acids and alkalis.”

 Furthermore, para 28, when discussing the handling of organic peroxides, states that: –

“… All containers and equipment which come into contact with peroxides must be compatible. Suitable materials include glass, porcelain, polyethylene and 316 grade stainless steel.”

Firevault – Walk In Fire Rated Stores

Walk In Fire Rated Stores Stores

The FireVault storage module provides the highest level of safety instantly for the secure storage of all flammable materials. All areas of industry currently employ flammables in their processes from petroleum products to industrial chemicals.

Manufactured to the highest standards utilising only those fireproofing materials, which have been tested to BS 476, part 22, FireVault Stores comply with all relevant Health & Safety Regulations, Insurance requirements and environmental standards such as IS310, ISO 14001, EMAS and IPC licensing.

Standard features include, full width spillage collection sumps, up to 5 hour fire rated composite wall panels, insulated self-closing doors, intumescent ventilation panels, fixed shelving, anti-static grounding connections, fully welded, leak tested bunds, galvanized grid mesh floors. A range of optional extras are also available for the Firevault units including ex-rated electrical fittings.         

All Firevault units are delivered to site fully assembled and ready for immediate use. No special site works are required and at any future time, they can easily be relocated by forklift truck or crane, thereby offering excellent flexibility.
The most common Firevaults are the Walk In Stores used for small container storage (25L cans, Winchesters etc) and feature:
