COSHH Compliant | 30-Minute Fire Resistance | 12-Month Warranty
The ChemBank CBC4 meets all relevant HSE regulations governing the storage of hazardous materials and chemicals. The unit provides 30 minutes of fire resistance, giving time to evacuate should a fire break out. All Armorgard products are built in the UK and come with a 12-month manufacturer's warranty.
More About This Product
The Armorgard ChemBank CBC4 is a tall chemical storage cabinet designed for the secure outdoor storage of hazardous substances and chemicals. Fully COSHH compliant, the CBC4 features a welded and tested 85-litre sump base to contain spillages, high and low level ventilation to prevent fume build-up, and 30-minute fire resistance. The cabinet includes one internal shelf as standard for organised storage. Finished in distinctive traffic yellow with pre-fitted hazard warning signage, the CBC4 is easily distinguishable from fuel storage units on site. Constructed from 2mm and 3mm steel with twin 5-lever deadlocks and a unique anti-jemmy system, the cabinet provides maximum security. Heavy-duty 1000N gas struts and a safety catch ensure safe lid operation, while forklift skids enable easy transportation around site.
Suitable Applications
The ChemBank CBC4 is designed for the secure outdoor storage of chemicals, hazardous substances, paints, solvents, cleaning agents, adhesives, and other materials requiring COSHH-compliant storage. The taller cabinet design with internal shelf provides greater storage capacity and organisation compared to the CB2. The distinctive yellow colour helps distinguish chemical stores from fuel stores (which use red FlamBank units). Suitable for construction sites, manufacturing facilities, workshops, warehouses, and any workplace handling hazardous chemicals.
Suitable Applications
Site storage of oils, fuels, solvents, paints, adhesives and other hazardous liquids where a spill must be contained rather than reaching a drain or watercourse. Used across construction, plant depots, workshops and any operation storing chemicals under COSHH.
The bunded sump is the reason for the product. A spill inside the unit is captured rather than escaping, which is both a COSHH requirement and an environmental one — a discharge to a watercourse is an offence regardless of whether it was an accident.
Bunding, Fire Resistance and Segregation
The sump is the product. A bunded store captures a spill or a leaking container rather than letting it reach the ground, a drain or a watercourse. The sump capacity determines how much can be contained, and the conventional rule is that it should hold a meaningful proportion of the total stored volume — check the capacity against what you intend to keep in it rather than filling the unit to its physical limit.
Fire resistance buys time. A rated store is not fireproof; it holds back a fire long enough for people to get clear and for the fire service to arrive. That matters most where the store sits close to a work area or a boundary.
Segregation matters as much as containment. Incompatible substances stored together can react — oxidisers with fuels, acids with alkalis. A single bunded store keeps a spill contained, but it does not keep incompatible chemicals apart. Check your COSHH assessment for what may share a store.
Ventilation. Solvent vapours accumulate in a sealed space. Where the store holds anything that gives off vapour, ventilation is part of the safe arrangement rather than an optional feature.
Safety Information
- Store only substances your COSHH assessment permits to share a store.
- Do not exceed the sump capacity with the total volume stored.
- Keep incompatible substances separated — a bund contains a spill, it does not prevent a reaction.
- Keep the store locked and the keys controlled.
- Keep clear of ignition sources where flammable liquids are stored.
- Check the sump is empty and clean before use and after any spill.
- Ensure hazard signage reflects the actual contents.
- Follow the substance safety data sheets and your site COSHH assessment.
Inspection and Maintenance
The sump is the part that has to work, so it is the part to check. It must be empty, clean and free of standing water — a sump already holding rainwater or an old spill has no capacity left for the next one. Check the seams and welds for corrosion, since a sump that leaks is not a bund.
Inspect the door seals and locks, and confirm both keys turn freely. Check the galvanising and powder coating for damage, particularly around the base where spills sit and at the door edges where wear concentrates. Confirm hazard signage matches what is actually stored inside, which drifts over time as contents change.
Frequently Asked Questions
Q: Is the ChemBank CBC4 COSHH compliant?
Yes. The CBC4 meets all relevant HSE regulations governing the storage of hazardous materials and chemicals, including COSHH (Control of Substances Hazardous to Health) requirements.
Q: What is the difference between the CB2 and CBC4?
The CBC4 is the taller model (1275mm high vs 670mm) with greater storage capacity. The CBC4 includes one internal shelf as standard and uses heavier-duty 1000N gas struts compared to the CB2's 300N struts. Both have the same 85-litre sump capacity and the same width and depth.
Q: Can the ChemBank be used outdoors?
Yes. The CBC4 is fully galvanised and powder coated for maximum durability and is suitable for outdoor storage of chemicals. The tough welded construction provides protection from both thieves and the elements.
Q: What does the sump capacity mean in practice?
It is how much liquid the store will contain if a container leaks. Check it against the total volume you intend to store rather than filling the unit to its physical limit — the bund only works if it can hold what escapes.
Q: Does fire resistance mean fireproof?
No. A rated store holds back a fire for the stated period, which buys time for people to get clear and the fire service to arrive. It is not indefinite protection.
Q: Can I store any chemicals together?
Only what your COSHH assessment permits. A bund contains a spill; it does not stop incompatible substances reacting. Oxidisers and fuels, acids and alkalis should not share a store.
Q: Why does ventilation matter?
Because solvent vapours accumulate in a sealed space and can reach a flammable concentration. Where the store holds anything that gives off vapour, ventilation is part of the safe arrangement.
