Requirements for the selection of insulation materials in buildings located in explosion-hazardous areas
Thread Content
As the title suggests, what materials should be used for insulation in factories located in explosion-hazardous areas (including the roofs), and what are the requirements? For example, could flammable materials such as polyurethane be used? Are there any standards or documents that impose such requirements? Please, experts, discuss this.
In areas with explosion hazards, insulating materials must not be flammable materials such as polyurethane or polystyrene boards, or PVC foam boards; instead, flame-retardant materials like rock wool, glass wool, and perlite should be used.
General buildings need to take into account basic fire resistance ratings, and this should also be considered in areas at risk of fire and explosion. Check the provisions of GB 50160
Classification of combustion performance for building materials and products GB8624-2012
Reference for Class-1 factory building design: 1. The roof deck consists of colored profiled steel sheets + centrifugally spun glass fiber insulation + a waterproof and breathable layer, a layer of spun polyethylene and polypropylene membranes + aluminum-magnesium-manganese roof panels. 2. The exterior wall panels are made of rock wool-cored steel plates and blast-resistant walls
This is the classification for combustion performance. Are there any requirements specifying which type of material should be used in particular environments?
50160 does not specify any requirements for insulation materials in the factory building.
