GB 13561.1-2009 Safety rules on port's continuous handling facilities — Part 1: Grain silos system
1 Scope
This part of GB 13561 specifies the basic requirements for the layout and structure, process design and loading and unloading equipment, electrical and monitoring systems, electrostatic protection, ventilation and dust removal, fire protection facilities, suffocating and safety management, as well as fire and explosion prevention of grain silos systems in ports.
This part is applicable to the fire and explosion prevention design, safety facility configuration and safety management of grain silos systems in ports. Other grain silos systems may also refer to it for use.

3 Terms and definitions
For the purposes of this part of GB 13561, the following terms and definitions apply.
3.1
silos
vertical containers for storing bulk materials. In this part, it refers to vertical containers for storing bulk grains.
3.2
silos system
general term for silos, working buildings (towers), filling rooms, transfer towers, corridors and other structures, as well as loading and unloading equipment, conveying equipment, process equipment and other auxiliary facilities
3.3
grain dust
solid particles produced during the production and storage of grains that can remain suspended in the air for a relatively long time are non-conductive and flammable dust
3.4
dust explosion hazardous area
areas where combustible dust and gaseous oxidants (or air) are present
3.5
secondary explosion
phenomenon that in the event of a dust explosion, the shock wave from the initial explosion raises the deposited dust, thus forming a dust cloud, which is ignited by the subsequent flame to cause a continuous explosion
3.6
the protection for grain dust explosion
techniques to prevent the combustion and explosion of grain dust, and reduce the loss in the event of combustion and explosion of grain dust
3.7
explosion pressure venting
a protective method to limit explosion overpressure: opening the set explosion venting device to release unburned mixtures and combustion products, to prevent the pressure from rising beyond the designed strength (anti-explosion strength) of the containment body, thereby protecting the containment body
