Safety Hazards of Container Houses

Container houses have various safety hazards in terms of fire safety, living environment, and other aspects, as detailed below:

Fire Safety Hazards

• Non-compliant construction materials: To save costs, some container houses use flammable core materials such as polystyrene and polyurethane foam, which have poor fire resistance and can be ignited by sparks from electrical welding or cigarette butts.
• Rapid combustion and high toxicity: The flammable sandwich materials melt, deform, and drip at 80℃, triggering more severe combustion. Moreover, the combustion products are highly toxic, posing a threat to human life.
• Difficulty in firefighting: The fire spreads rapidly, and the container houses are prone to collapse. The iron sheet wrapping structure obstructs the water jet from fire hoses, increasing the difficulty of rescue operations.
• Difficulty in escape: Black thick smoke is produced during combustion, and toxic fumes accumulate in the rooms, making it difficult for trapped people to survive and increasing the risk of casualties.
• Poor fire resistance of the building: The steel structure supports are prone to deformation and collapse under high temperatures, hindering personnel evacuation and material rescue.
• Narrow passageways: Some units do not reserve safety passageways in compliance with regulations to expand the usable area, obstructing personnel evacuation in case of fire.

Living Environment Hazards

• Inadequate ventilation and lighting: When the space is enclosed and the design is unreasonable, it can lead to poor ventilation and lighting, affecting living comfort.
• Poor sound insulation and heat insulation: Improper material selection results in insufficient sound insulation and heat insulation performance, reducing living quality.
• Unreasonable bed size: The single beds in some container houses are too small (e.g., 195 cm long and 90 cm wide) to meet the needs of tall people.
• Water leakage: Water leakage occurs in areas such as sinks and floors, affecting normal use.
• Cramped space: The aisles in double-bed rooms are narrow, and the ceiling height is low, resulting in a poor living experience.

Other Safety Hazards

• Fixing issues: Color steel plate container houses are lightweight and may be blown away by strong winds of level 8 or typhoons, posing a risk of overturning.
• Stacking issues: Color steel plate container houses are lightweight, and stacking them more than 3 layers high may lead to collapse due to structural instability.
• Legal compliance: If they do not meet safety standards, they may violate the Work Safety Law and the Regulations on the Administration of Work Safety in Construction Projects, facing penalties. Unauthorized construction may constitute an illegal building and face demolition.
