Compliance overview
Scope and applicability
This standard applies to the engineering and process design, production, processing, storage, and equipment operation and maintenance in places with dust explosion hazards. It covers general safety principles, building structures, ignition prevention, explosion control, and dust collection systems. This standard is mandatory for all facilities handling combustible dust. It does not apply to underground coal mines, fireworks, explosives, or strong oxidizers.
Technical requirements
The standard specifies comprehensive requirements for dust explosion prevention and protection. It mandates the identification of hazardous areas and classification into Zones 20, 21, and 22 based on the frequency and duration of explosive dust atmosphere presence. For structural layout, facilities with dust hazards must not be in public or residential areas and should preferably be single-story frame structures with light roofs. Buildings must have adequate venting areas and clear evacuation routes. The standard details strict measures to prevent ignition from spontaneous combustion, open flames, hot surfaces, electrical arcs, and friction sparks, referencing GB 50057 for lightning protection and GB 12158 for static electricity control. Regarding explosion control, process equipment must employ one or more methods such as explosion venting, suppression, isolation, or containment, but isolation cannot be used alone. It also introduces specific requirements for dust collection systems, prohibiting the sharing of systems between different dust categories and banning positive-pressure conveying for aluminum and magnesium dust.
Testing methods
The standard primarily outlines safety regulations and design criteria rather than specific laboratory testing methods. However, it references several associated standards for performance evaluation, such as GB/T 15605 for dust explosion venting guidelines, GB/T 18154 for monitored explosion suppression devices, and GB/T 24626 for explosion-resistant equipment. Compliance involves verifying equipment design strength, venting areas, and the operational parameters of dust collection and suppression systems.
