GB 13561.1-1992

This standard specifies safety requirements for the design, operation, and maintenance of continuous grain handling systems within port silo facilities. It applies specifically to bulk grain silo systems at Chinese ports, covering equipment such as conveyors, elevators, and dust control systems to prevent fires, explosions, and mechanical hazards. The standard is used by port operators, engineers, and safety inspectors to ensure compliance with national safety protocols during grain loading, unloading, and storage processes.
