Can Container Houses Have a Kang Bed-Stove?

It is not advisable to build a kang bed-stove inside a container house due to serious fire safety hazards. The specific reasons are as follows:

Poor fire resistance of steel structures, prone to collapse in fires

The main structure of container houses is usually supported by steel structures. Steel loses its strength rapidly in high-temperature environments. When the temperature reaches around 500℃, the yield strength of steel drops to about 50% of its normal-temperature strength; when the temperature exceeds 600℃, the strength of steel drops sharply, resulting in a significant reduction in the structural load-bearing capacity. A kang bed-stove generates continuous high temperatures during use. If the fire source is not managed properly, it may cause a fire. Once a fire breaks out, the steel structure of the container house will quickly soften, deform, or even collapse under high temperatures, seriously endangering the lives of personnel.

Flammable core materials accelerate the spread of fire

To save costs, some container houses use flammable materials such as polystyrene and polyurethane foam as core materials. These materials are highly flammable. Once exposed to high-temperature sparks, short-circuited wire droplets, or open flames, they will immediately catch fire and burn extremely fast. For example, the burning speed of polystyrene foam can reach several centimeters per second, and polyurethane foam burns even faster. Moreover, during combustion, they produce a large amount of toxic gases such as carbon monoxide and hydrogen cyanide. If a kang bed-stove is built inside a container house, the fire source may directly contact these flammable materials, quickly triggering a fire and causing the fire to spread rapidly, increasing the difficulty of rescue and the risk of casualties.

Difficult fire source management, prominent safety hazards

The use of a kang bed-stove requires a continuous supply of fire sources such as coal and wood. Building a kang bed-stove inside a container house makes fire source management more difficult, and it is easy to cause a fire due to improper operation or negligence. For example, if the coal in the kang bed-stove is not completely extinguished, it may cause a fire due to rekindling; if the flammable items around the kang bed-stove are not cleaned up in a timely manner, they may also be ignited by high temperatures. In addition, the space inside a container house is relatively enclosed with poor ventilation. Once a fire occurs, smoke and toxic gases will quickly accumulate, causing personnel to suffocate or be poisoned.

In conclusion, from the perspective of fire safety, it is not recommended to build a kang bed-stove inside a container house.
