Fire Safety in Container Workforce Camps: What to Specify Before You Buy

The fire performance of a container workforce camp is decided long before the units reach site — in the panel core, the floor build-up and the electrical installation. Wanbang flat-pack container houses are built with colour-steel rock wool sandwich panels carrying a Class A (non-combustible) fire rating, a cement fibre floor, concealed wiring and industrial-grade switches, with a service life of 10–15 years. For a camp accommodating hundreds of people, those are the details that determine whether a fire stays contained or spreads between units.

Short answer: Specify the panel core first — rock wool sandwich panels rated Class A (non-combustible) are the base of camp fire safety. Then confirm the floor build-up, the way wiring is run, and the grade of electrical fittings. For a standard Wanbang flat-pack container house, the published specification is Class A fire resistance with a rock wool core, a cement fibre floor, concealed wiring, industrial-grade switches, and a 10–15 year service life.

What decides the fire performance of a container house?

A container housing unit is a steel frame wrapped in insulated sandwich panels. Fire performance is set by three elements, in order of importance:

• The panel core. This is what burns — or does not. Rock wool is non-combustible; some other common cores are not.
• The floor build-up. Camps run heavy foot traffic and services through the floor; a cement fibre board floor is load-bearing, fire-resistant and slip-resistant.
• The electrical installation. Wiring method and the grade of switches and fittings decide how much of a fire risk the services themselves present.

The structural frame is steel, so it does not contribute fuel. That is why, in practice, the conversation about fire safety in a container camp almost always comes down to what is inside the walls and under the floor.

Why does the panel core matter more than anything else?

In a camp, units sit close together in rows, often with shared walkways, and they are occupied around the clock. If a wall panel core can burn, a fire in one unit has a path into its neighbours.

Wanbang flat-pack and quick-assembly container houses use colour-steel rock wool sandwich panels, described by their material performance as fire-resistant, moisture-resistant and thermally insulating, with a Class A fire resistance rating — non-combustible. Rock wool is the panel core; the steel skins on either side are non-combustible as well. Panels are produced in 50 mm and 75 mm wall thicknesses, so the same unit can be specified for a temperate site or a site with a wider temperature swing.

What does a Wanbang camp unit specify?

Steel components carry a baked enamel finish that is resistant to fading for up to five years, and the drainage system is a centralized, organized internal arrangement that keeps roof water away from the building envelope — a detail that matters as much for keeping moisture out of panels as for drainage itself.

Which parts of a camp carry the highest fire risk?

Container camps are not single-purpose buildings. A full camp typically combines accommodation with working and catering functions — the Wanbang unit range covers meeting rooms, reception rooms, offices, dormitories, staff kitchens, staff canteens and restrooms.

The practical implication is layout planning, not just product specification: group the higher-risk functions, keep sleeping blocks clear of them, and keep escape routes open. That planning is normally settled with the camp designer once the unit mix is known.

What should you ask a supplier before you buy?

1. What is the panel core, and what fire rating does the panel carry?
2. What is the floor build-up, and is it fire-resistant as well as load-bearing?
3. How is the wiring run — concealed within panels, or surface-mounted?
4. What grade of switches and electrical fittings is supplied?
5. Which units will be used for kitchens, canteens or plant, and how are they separated?
6. What local fire requirements apply at the destination, and what evidence will the supplier provide?

The last point is worth stating plainly: fire requirements vary by country and by project, and they are normally confirmed with the local authority or the project engineer. What a supplier controls is the specification of the unit — panel core, floor, wiring and fittings — and that is where the questions above should be answered in writing at quotation stage.

Does the same specification work in hot, humid or desert climates?

Yes, with the environment taken into account. Camp projects delivered by Wanbang include a 360-unit camp for a steel plant in Lagos, Nigeria, specified for heat and humidity; more than 500 units for a nickel mining camp at Zamboanga in the Philippines, with anti-corrosion and anti-rust treatment and no concrete foundation required; and a 5,050 m² living compound for the VAN project in Iraq, engineered for high-temperature, sand-laden conditions. In each case the panel specification stays the same and the finishing and protection details change with the site.

Frequently asked questions

Are container houses fire-resistant?

It depends on the panel core. Wanbang flat-pack and quick-assembly container houses use colour-steel rock wool sandwich panels with a Class A fire resistance rating — non-combustible. Always confirm the core material rather than assuming all sandwich panels behave the same way.

What does "Class A non-combustible" mean for a camp?

It describes the fire performance of the panel material: the core does not support combustion. In a camp where units stand in rows and are occupied at night, that is the property that limits how far a fire can travel through the walls.

Can a container unit be used as a kitchen or canteen?

Yes — staff kitchens, canteens and restrooms are part of the standard unit range alongside offices, dormitories and meeting rooms. Because cooking areas carry a higher risk, they are normally grouped and separated from sleeping blocks in the camp layout.

How long does a container camp unit last?

The published service life of the Wanbang flat-pack container house is 10–15 years. Units are also designed for reuse and relocation, which is why they are widely used on projects that move from site to site.
