Linhe Residential Container House
The Linhe residential container house is a temporary living or office space transformed from a container base, featuring eco-friendliness, energy efficiency, flexible assembly, and easy disassembly and transportation. However, attention must be paid to fire safety and compliance in use.
I. Product Types and Uses
Residential container houses can be classified into standard container houses, foldable extension houses, quick-assembly container houses, etc., based on their structure and use. They are commonly used as worker dormitories on construction sites, as well as for field operations, offices, temporary housing in tourist attractions, and rental housing. For example, Anhui Richuang Construction Engineering Co., Ltd. provides 30-square-meter construction site dormitory containers, while Hangzhou Suge Construction Technology Co., Ltd. offers customizable foldable extension houses to meet different scenario needs.
II. Core Advantages and Material Selection
Their core advantages lie in eco-friendliness, energy efficiency, and rapid construction, but material selection directly affects safety. High-quality products typically use A-grade fireproof materials such as rock wool boards and fireproof cotton as fillers, meeting fire safety requirements on construction sites. In contrast, some low-cost products use flammable sandwich materials like polystyrene and polyurethane foam to save costs, posing significant safety hazards. For instance, a container house fire in Linping District, Hangzhou, in 2025 was caused by flammable materials, resulting in property damage.
III. Fire Safety Regulations
When using residential container houses, strict adherence to fire safety regulations is essential:
- Material Fire Rating: Prioritize A-grade fireproof materials and avoid using flammable sandwich panels;
- Heat Source Management: Keep heat and fire sources away from the house and maintain a safe distance for open-flame operations;
- Electrical Safety: Protect wires and cables with sleeves and use metal galvanized boxes for sockets and switches, installed visibly;
- Spacing Requirements: Maintain at least a 6-meter safety distance between houses;
- Fire Extinguishing Equipment: Equip the interior and exterior with simple fire extinguishing equipment and regularly check its effectiveness.
IV. Compliance in Use and Case Warnings
In addition to fire safety, compliance in use must be noted. For example, Xingshan County Feige Auto Repair Shop used a container panel house under a highway bridge to store parts, which, while not involving environmental impact assessment approval, required ensuring noise and dust did not disturb residents. Furthermore, a container house fire in Tianjin Binhai New Area in 2018 resulted in two deaths, exposing issues such as flammable materials and difficulties in escape, highlighting the necessity of compliance in use and safety management.
