Fire Protection Requirements for Container Houses

The fire protection requirements for container houses mainly include selecting compliant fire-resistant materials, standardizing construction and usage operations, equipping fire-fighting facilities, and maintaining safe distances, among other aspects. Details are as follows:

Selecting Compliant Fire-Resistant Materials

• Panel Fire Rating: For container houses and mobile panel houses used for personnel living and office scenarios, A-grade rock wool fire-resistant panels must be selected. This material can effectively block the spread of fire, ensure personnel safety, and meet fire inspection conditions. Some national standards require the fire rating of container mobile houses to be above B1 grade. Products from compliant manufacturers use fire-resistant materials that meet the standards, which can effectively delay the spread of fire and buy time for escape. In contrast, white-label products often use flammable materials with a fire rating of only C grade, posing a high fire risk.
• Structural Component Fire Treatment: The structural components of mobile panel houses, such as roof trusses, purlins, and girders, are assembled by welding steel. During the production process, attention should be paid to the fire treatment of steel to improve its fire resistance.

Standardizing Construction and Usage Operations

• Keeping Away from Open Flame Operations: During the construction of container houses, the core materials should be kept away from open flame operations such as electric welding and gas welding to avoid fires caused by high temperatures.
• Heat and Fire Source Management: During use, heat sources and fire sources should not be placed close to steel plates and should be kept at a certain distance. If a kitchen is set up in a color-steel panel house, a thermal insulation layer is required, and the walls should be equipped with fire-resistant rock wool insulation layers.
• Wire and Cable Handling: Wires and cables should not pass through the core materials. If passage is necessary, protective sleeves should be added. Socket and switch boxes should be made of metal galvanized boxes and installed in an exposed manner to prevent fires caused by short circuits.

Equipping Fire-Fighting Facilities

Simple fire-extinguishing equipment should be equipped indoors and outdoors. If conditions permit, fire alarms should be installed to facilitate rapid evacuation and timely alarm in the event of a fire.

Maintaining Safe Distances

Color-steel panel houses should maintain a safe distance of at least 6 meters from each other to prevent the spread and expansion of fires.
