Guidelines for the Safe Renovation of Vehicle Loading and Unloading Facilities for Flammable Liquids, Liquefied Hydrocarbons, and Liquefied Toxic Gases in Shandong Province
Thread Content
I have a question: In order to further improve the level of informational and intelligent supervision over the road transport of hazardous chemicals and to promote the successful practices from Dongying, on the afternoon of November 9th, the **Safety Committee of Shandong Province organized a field meeting on the informational supervision of the entire process of road transport of hazardous chemicals across the province in Dongying. “We have implemented a set of seven safety interlocks, including those for lower piping arrangements and the proper positioning of flexible hoses, interlocks for static electricity discharge from vehicles, interlocks for oil spills, interlocks for static electricity discharge from human bodies, interlocks related to electric key boxes, interlocks for detecting and alerting to flammable gases, and interlocks for explosion-proof vapor flow detectors. In the event of any abnormalities or improper operations during loading and unloading, the entire system will prevent such operations from proceeding or will stop them......” On the afternoon of November 9th, staff at the hazardous chemicals transportation vehicle loading and unloading area of Kenli Petrochemical Group Co., Ltd. explained these measures to the participants from across the province who came to observe the site. The “seven-interlock” system significantly enhances the intrinsic safety level during loading and unloading operations, effectively preventing accidents involving hazardous materials vehicles during these processes. As for this vehicle static discharge interlock, that’s simple. But how can this human body static discharge interlock obtain its signal? Guidelines for the Safe Renovation of Vehicle Loading and Unloading Facilities for Flammable Liquids, Liquefied Hydrocarbons, and Liquefied Toxic Gases in Shandong Province (Trial), issued on June 9 – these guidelines do not specify any requirements regarding the discharge of static electricity from the human body
How did you know that a meeting would be held in Shandong in 10 days? Send the guide first for everyone to take a look

Lowering the vehicle requires static discharge; is it the vehicle’s static discharge interlock system? If there’s no outlet for discharging human body static, how can an interlock be established? Combustible gases go into the GDS system and the loading system; they are not the same system – is communication interlocking used? Is it still the GDS alarm output DO point interlock? The chain becomes more and more complex as it develops
If the human body static discharge device is standalone, it is necessary to purchase a signal connection system with dry contact outputs for interlocking purposes； If the human body static electricity, the electronically controlled key, and the static electricity oil spill protector are installed as an integrated unit, there is no need for a separate connection for the human body static electricity discharge signal; the human body static electricity signal is already interlocked with the static electricity oil spill signal.
You also need this: manual quick emergency shut-off valve. It must now be installed in all existing stockpiles; it’s essential at key junction points, and for all sizes the time required to operate it manually must not exceed 30 seconds.

:) Our company currently uses 9 interlocks; the addition of more interlocks is aimed at ensuring safety both for the company itself and its operations, not for compliance with regulations
That’s the right way to think – safety first, prevention foremost!
