Technical specifications
| Specification | Value |
|---|---|
| Materials | polyethylene for bases, acids and aggressive chemicals; steel for non-corrosive polluting or flammable products |
| Usable volume | size around the volume, number and type of containers; no universal value is published |
| Formats | low plastic platform for leaks or wash water; documented steel configuration for 8 × 220 L drums or 2 × 1,000 L tanks |
| Chemical compatibility | check against the safety data sheet; polyethylene is documented for bases/acids and steel for non-corrosive products |
| Layout | on the floor, under racking or in a mesh cabinet depending on containers, access and plan; anchoring and loads to confirm |
| Options | plastic or hot-dip galvanized steel grating; mesh cabinet with lockable doors; other options to confirm |
Storage catalogue, printed pages 50–51. The steel configuration is shown for eight 220 L drums or two 1,000 L tanks: these figures describe stored containers, not usable retention volume. No chemical compatibility matrix, usable capacity, general certificate or single regulatory rule is published.
How do you choose and lay out a retention tray?
Sizing starts with the products, containers and premises:
- Share the safety data sheets, product families and containers actually stored
- Use polyethylene for the documented bases, acids and aggressive chemicals; use steel for the documented non-corrosive polluting or flammable products
- Record unit volume, number of drums, cans or tanks and required usable volume; the applicable rule must be confirmed for the site and products
- Choose a low platform to ease drum loading and collect leaks or wash water where that use is required
- Check footprint, access, handling and compatibility with racking or a mesh cabinet before ordering
