Ningbo Non-standard Container House
Ningbo non-standard container houses are temporary buildings customized and modified based on containers, featuring flexibility and certain limitations, and requiring attention to fire safety during use.

Definition and Characteristics
Non-standard container houses are products resulting from the non-standard modification of standard containers. They break through the fixed specifications and usage limitations of standard containers and can be customized according to different needs, such as adjusting size, shape, and internal layout, to adapt to diverse usage scenarios, such as temporary offices, residences, and commercial displays. As a coastal city, Ningbo has a significant demand for temporary housing in the construction and logistics sectors. Non-standard container houses have a certain market presence in the area due to their customizability and flexibility.
Common Uses
In Ningbo, non-standard container houses are commonly found on construction sites, serving as temporary dormitories for workers to meet their accommodation needs during construction. They are also used for field operations, providing temporary work and rest areas for staff. Additionally, they can function as office spaces to meet some temporary office needs. In tourist attractions, they can serve as temporary facilities to provide services to tourists or as unique accommodations.
Fire Safety Hazards
Non-standard container houses have numerous fire safety hazards. Some temporary buildings on construction sites and illegal structures of enterprises use flammable materials such as polystyrene and polyurethane foam as core materials to save costs. These materials have poor fire resistance and safety, and can be ignited by electrical welding sparks and cigarette butts. Once flammable and combustible sandwich materials catch fire, they burn rapidly, producing molten deformation and dripping at 80℃, which can trigger more severe combustion, and the combustion products are highly toxic. After a fire breaks out, the flames spread extremely quickly, easily causing the collapse of container houses. Once collapsed, they are wrapped in iron sheets, making it difficult for firefighting water cannons to shoot water inside, increasing the difficulty of firefighting and rescue. When polystyrene and polyurethane burn, they emit thick black smoke, and toxic smoke accumulates inside the rooms, making it difficult for trapped people to escape and prone to casualties.
Safe Use Recommendations
To ensure safety, non-standard container houses should preferably be made using rock wool boards and fireproof cotton as fillers, achieving an A-grade fire resistance rating or above. During use, heat sources and fire sources should not be placed close to container houses, and open-flame operations should maintain a certain distance. Electrical wires and cables should be protected with sleeves, and sockets and switch boxes should be made of metal galvanized boxes and installed openly. Simple firefighting equipment should be equipped both inside and outside, and container houses should maintain a safety distance of at least 6 meters from each other.
