Safety Hazards of Container Houses
Container houses have multiple safety hazards in terms of fire safety, living environment, structural safety, and legal compliance. Details are as follows:
Fire Safety Hazards: To save costs, some container houses use flammable materials such as polystyrene and polyurethane foam as core materials. These materials have poor fire resistance, and sparks from electrical welding or cigarette butts can ignite them. Once ignited, the flammable core materials burn rapidly, melting and deforming at 80℃, dripping and exacerbating the spread of the fire, and producing highly toxic combustion products. After a fire breaks out, it spreads rapidly, and container houses are prone to collapse. The iron-sheet-wrapped structure makes it difficult for firefighting water cannons to penetrate the interior, increasing the difficulty of rescue operations. Meanwhile, the thick black smoke and toxic gases produced by combustion make it difficult for trapped individuals to escape, leading to casualties. In addition, container houses are mostly supported by steel structures, and high temperatures during fires can easily cause the steel structures to deform and collapse, hindering personnel evacuation and material rescue. Some user units, in pursuit of usable area, fail to leave safety passages that comply with regulations, further obstructing personnel evacuation.
Living Environment Issues: Container houses have enclosed spaces. If the design is unreasonable, inadequate ventilation and lighting can affect living comfort. Improper material selection can result in poor sound insulation and thermal insulation, making them stuffy in summer and cold in winter, and allowing external noise to easily penetrate, affecting rest quality. The limited space of container houses restricts activity areas, making it difficult to place large furniture and lacking in functionality. The layout of water, electricity, and other infrastructure may be incomplete, and drainage and ventilation systems may have defects, affecting daily life.
Structural Safety Risks: Color-steel-plate container houses are relatively lightweight and may be blown away by strong winds of magnitude 8 or typhoons, requiring reinforcement. When multiple container houses are stacked, there may be safety hazards due to unstable structures. Compared to traditional houses, container structures are relatively thin and are at risk of collapse or damage when faced with extreme weather conditions such as strong winds and heavy rain.
Legal Compliance: According to relevant regulations, production and business premises and employee dormitories must maintain a safe distance, and temporary buildings must meet safety requirements for use. If container houses are used for human habitation, they must comply with safety standards; otherwise, they may face legal penalties. Unauthorized construction of container houses for human habitation may constitute an illegal structure and face the risk of demolition.
