CSC certificated 20ft side open chemical waste hazardous storage container

This is a **25G2 hazardous waste / dangerous goods container**, manufactured to ISO container specifications and fully CSC certified for intermodal transport.

The container floor is fitted with heavy-duty grating panels. Beneath the grating lies an integral bund sump (retention tank), which serves as a containment reservoir. In case of liquid leakage from hazardous waste or chemicals, all spills will be captured within this base sump, preventing dangerous liquids from leaking out of the container and contaminating the surrounding ground, fully meeting hazardous waste containment requirements.

Side wall ventilation louvers are installed continuously to maintain continuous air exchange inside the enclosure. They help dilute and vent harmful volatile vapors, avoiding the buildup of flammable or toxic gas inside the box.

A drain valve is fitted at the bund sump. When required, operators can open this valve to safely discharge collected residual liquid and spills from the containment base.

It adopts a special safety exit door design. The door locking system can be unlocked and opened **from inside the container**, offering emergency escape capability for personnel working inside.

The interior is coated with AkzoNobel heavy-duty wear-resistant paint. The coating withstands abrasion during loading, unloading and material handling and will not be easily scratched. All internal corners are rounded to ensure complete flow and discharge of waste and residual liquid during emptying.

Built with standard ISO corner castings, the unit can be stacked, lifted and transported on skeletal trailers like standard shipping containers. Heavy-duty double door locking mechanisms provide reliable security for hazardous material storage and transit.

Anti-Corrosion Coating System

For projects requiring enhanced corrosion protection, the steel surface can undergo Sa2.5 abrasive blasting before painting.

The available coating system includes:

● Zinc-rich epoxy primer

● Epoxy intermediate coat

● Polyurethane top coat

Paint thickness and coating adhesion can be inspected according to the agreed quality requirements.

The coating system helps protect the steel structure during transportation, outdoor storage and operation in demanding environments.

Flexible Project-Specific Customization

The Container can be manufactured according to customer drawings, equipment specifications and project requirements.

Customization options can include:

● Container dimensions

● Steel material

● Internal equipment layout

● Doors and access arrangements

● Electrical system requirements

● Thermal insulation

● Sound insulation

● Shelving

● Exterior color

● Customer logo

● Other project-specific accessories

This allows the container structure and internal configuration to be developed around the actual generator equipment rather than adapting the equipment to a fixed container design.

For projects requiring equipment to be assembled into a modular container configuration before delivery, the 20HQ structure provides a practical platform for integrating generator-related equipment.

The internal arrangement can be developed according to customer drawings and technical requirements.
