4m x 2m Insulated COSHH Flat Pack Storage Unit

This 4m x 2m insulated COSHH flat pack storage unit provides safe, compliant storage for hazardous substances, chemicals, fuels, paints, and solvents on construction sites, industrial facilities, and agricultural operations. For example, you can store fuels, paint tins, or chemical containers safely while meeting UK COSHH regulations. Therefore, this unit helps you maintain legal compliance while protecting your site from environmental contamination.

Why Choose a Flat Pack Design?

Standard containers cannot access tight or restricted sites. In contrast, this flat pack unit arrives as individual panels that you can carry through narrow routes and assemble on-site with basic tools . Consequently, you can install compliant chemical storage in courtyards, pedestrian routes, or sites with limited vehicle access. Moreover, the unit knocks down for relocation when your storage needs change . Thus, you gain flexibility for evolving site requirements.

Key Features of This Insulated COSHH Unit

The insulated construction and COSHH compliance make this storage unit stand out. For instance, 40mm thick polyurethane insulation in walls and roof maintains thermal stability for temperature-sensitive materials . Similarly, the heavy-duty galvanised steel chassis provides structural strength and durability. Furthermore, an 18mm OSB timber floor sits on a galvanised steel frame for robust load-bearing. Finally, the unit includes integrated forklift pockets and lifting eyes for easy repositioning .

COSHH Compliance – Meeting UK Regulations

This unit meets UK Control of Substances Hazardous to Health (COSHH) regulations for hazardous storage . First, a fully welded bunded sump (typically 960 litre capacity for 4m model) contains any leaks or spills, preventing ground contamination . Second, high and low level air vents prevent the build-up of hazardous fumes . Third, the unit includes relevant hazard warning signage for compliance. If you store chemicals, fuels, or solvents, this COSHH-compliant design protects your site and the environment.

Insulated Construction – Thermal Protection

The 40mm polyurethane insulation provides essential thermal stability. For example, the insulated walls and roof maintain a steadier internal temperature, protecting temperature-sensitive materials from extreme fluctuations . Likewise, the double-skinned insulated door with a double locking system ensures security. Furthermore, the insulated panels help reduce condensation and internal dampness. If you store paints, adhesives, or other temperature-sensitive hazardous substances, this insulated unit helps maintain product integrity.

Security and Fire Resistance

The unit includes robust security and fire safety features. For example, heavy-duty doors feature 5-lever deadlocks that are anti-snap and anti-pick, which can reduce insurance premiums . Likewise, jemmy-proof joints prevent forced entry . Furthermore, the unit offers up to 30 minutes fire resistance, protecting contents from external fire or containing internal incidents . If you store valuable or hazardous materials, these features provide peace of mind.

4m x 2m Dimensions – Generous Capacity

The 4m length provides substantial storage capacity while fitting in most site footprints. For example, the internal length measures approximately 3,790-3,840mm, offering generous space for pallets, drums, and IBCs . Likewise, the internal width of approximately 2,013mm accommodates standard pallets . Furthermore, the internal height of approximately 1,957mm allows for stacking . If you need larger capacity, consider our 4m x 2m unit for substantial hazardous storage requirements.

Flat Pack Delivery – Accessible to Any Site

The flat pack design solves site access challenges. For example, you can deliver the unit to any property location, even where containers cannot reach . Likewise, individual panels weigh approximately 50-100kg each, allowing two people to man-handle them into position . Furthermore, you can assemble the entire unit in around 10-15 minutes with basic tools . If your site has restricted access, this flat pack design eliminates delivery constraints.

What’s Included

First, every unit includes 40mm insulated wall and roof panels (double-skinned galvanised steel). Second, a galvanised steel base frame with integrated bunded sump catches spills. Third, we include an 18mm OSB timber floor . Fourth, you receive a heavy-duty insulated steel door with double locking system. Finally, we supply relevant hazard warning signage, high/low air vents, integrated forklift pockets, and lifting eyes .

For instance, you can request a specific RAL colour finish. Likewise, you can add internal shelving or racking. Furthermore, we can pre-assemble the unit before delivery for an additional charge . Contact our team for custom configurations.

Pros and Cons

Pros:

• COSHH compliant design (meets UK hazardous substance storage regulations)

• 40mm polyurethane insulation (thermal stability for sensitive materials)

• Flat pack delivery (access to restricted sites, man-handleable panels)

• Bunded sump (leak-proof, prevents ground contamination)

• 30-minute fire resistance (enhanced safety)

• High/low air vents (prevents fume accumulation)

• 5-lever deadlocks + jemmy-proof joins (high security)

• Integrated forklift pockets and lifting eyes (easy repositioning)

• Quick assembly (10-15 minutes, basic tools)

Cons:

• Requires level, firm ground for installation

Technical Specifications

Final Verdict

In summary, this 4m x 2m insulated COSHH flat pack storage unit delivers compliant, temperature-controlled hazardous substance storage for restricted access sites. As a result, you can safely store chemicals, fuels, and solvents while meeting UK regulations and protecting the environment. Consequently, one construction site manager installed this unit in a tight courtyard where a standard container could not fit, achieving full COSHH compliance. Therefore, choose this insulated flat pack unit if you need hazardous storage on a restricted-access site or require thermal protection for sensitive materials. If you don’t need insulation, consider our non-insulated COSHH unit. If you need a smaller footprint, consider our 2m x 2m or 3m x 2m models. Thus, request a free quote with your site access details and delivery postcode today.
