Safety Distances Between LPG Loading Arms and Tank Trucks
The safety distances between liquefied petroleum gas (LPG) loading arms and tank trucks are critical for ensuring safe loading and unloading operations. These distances involve fire prevention clearances, equipment layout, and other aspects.
一,Fire Prevention Clearances
The safety distances between LPG loading arms and tank trucks must meet fire prevention clearance requirements, specified as follows:
Total storage capacity under 50m³:
Fire prevention clearance between LPG storage tanks and off-site buildings/structures: at least 50m.
Distance from the outer wall of off-site industrial zones: at least 50m.
Distance from civil buildings: 40m.
Distance from the shoulder of off-site expressways, Class I/II highways: at least 20m.
Distance from the shoulder of off-site Class III/IV highways: at least 15m.
Distance from off-site overhead power lines: at least 1.5 times the pole height.
Distance from off-site Class I/II communication lines: at least 30m.
Total storage capacity 51–200m³ or single tank volume 20m³:
Distance from the outer wall of off-site industrial zones: at least 60m.
Distance from civil buildings: 45m.
Distance from the shoulder of off-site expressways, Class I/II highways: at least 25m.
Distance from the shoulder of off-site Class III/IV highways: at least 20m.
二,Equipment Layout
In the layout of LPG loading arms and tank trucks, safety distances must also be considered. For example, when loading arms for different materials are arranged on the same parking platform, if the clearance between loading arms cannot meet the 4m requirement, a staggered front-to-back arrangement can be used to satisfy safety standards.
三,Other Safety Requirements
In addition to the above fire prevention clearances and layout requirements:
Drivers and escorts of LPG tank trucks must undergo professional training, pass qualification exams, and work with valid certificates.
They must be familiar with:
Physical and chemical properties of LPG.
Technical specifications of tank trucks and LPG containers.
Safety operation procedures for loading/unloading.
Fire prevention and extinguishing knowledge.
Emergency response measures for accidents.
Conclusion: The safety distances between LPG loading arms and tank trucks should be determined in accordance with relevant codes and standards, ensuring that loading/unloading operations are conducted while meeting these safety requirements.
