Compliance overview
Scope and applicability
This standard applies to the design, operation, management, and inspection of dust explosion prevention and protection in tobacco processing systems. It covers production processes such as leaf redrying, primary processing (cut rag), cigarette making, and reconstituted tobacco production. It is specifically targeted at facilities handling combustible tobacco dust and does not apply to non-combustible dust environments. The standard is intended for engineers and safety managers overseeing tobacco manufacturing facilities.
Technical requirements
The standard outlines comprehensive general requirements, starting with the identification and assessment of dust explosion risks. Enterprises must establish a hazardous area classification map dividing tobacco production areas into Zones 20, 21, 22, and non-hazardous zones based on the frequency and duration of explosive dust presence. It mandates the implementation of technical measures to mitigate risks in these classified zones. For process equipment, the standard specifies ignition source prevention measures. Key requirements include installing magnetic separators at raw material inlets to remove foreign objects, enclosing specific cutting components with dust extraction hoods, and installing spark detection and extinguishing systems on dry central dedusting pipelines. Equipment must be designed to prevent friction and collisions that could generate sparks. Regarding dedusting facilities, the standard sets strict criteria for dust collection rooms and systems. It mandates negative pressure dedusting methods and prohibits sharing systems across different fire zones. Dust collectors must be constructed of steel, designed to withstand maximum explosion pressure, and equipped with monitoring devices for pressure differentials and temperatures. Dry electrostatic precipitators and gravity settling chambers are explicitly prohibited. The standard also details requirements for ash conveying systems (pneumatic, screw, and manual), mandating enclosed designs and specific minimum air velocities to prevent dust accumulation. Electrical safety requirements align with GB 50058 and GB/T 3836 series, specifying proper equipment selection, anti-static bonding, and grounding for all metal components in hazardous zones.
Testing methods
The standard describes verification methods primarily based on on-site inspections and the review of design documentation. Compliance is confirmed by examining design files, equipment manuals, and certificates. Verification includes checking the physical installation of magnetic separators, spark detection systems, and dust collector structural integrity. It also involves reviewing maintenance logs, training records, and dust cleaning schedules to ensure adherence to safety management requirements.
FAQs
What products and systems are regulated under GB 18245-2024?
It applies to the design, operation, management, and inspection of dust explosion prevention and protection in tobacco processing systems, including leaf redrying, primary processing, and cigarette making.
What are the main updates from the previous GB 18245-2000 version?
The 2024 version introduces the term "dedusting room", adds requirements for hazardous area classification (Zones 20, 21, 22), and includes new safety technical requirements for dust removal systems, pneumatic ash conveying, and maintenance operations.
Does GB 18245-2024 reference other international or national standards?
It references several core Chinese standards, such as GB 15577 for general dust explosion safety, GB/T 3836.1 and GB/T 3836.2 for electrical equipment in explosive atmospheres, and GB 50058 for building lightning protection and electrical design.
