Is it necessary to connect an anti-static jumper for loading and unloading liquid caustic?

Let’s discuss whether an anti-static jumper is needed between the liquid caustic handling equipment and the vehicle Our company has always taken them on; I don’t think it’s necessary. I’m not sure if my idea is right.

As is well known, it won’t catch fire on its own; therefore, it’s not a problem if static sparks are generated between the liquid level and the loading arm during loading and unloading operations. However, if there is a high concentration of flammable gases inside the tank (after a product change), within the LEL range, or if the concentration of gases in the surrounding area is high, then danger may arise... So it’s necessary to take relevant factors into consideration...
If it is simply the unloading of liquid caustic, then it is not necessary.
In my opinion, it is necessary to require that static electricity elimination devices be installed in the loading and unloading areas when designing relevant regulations. Timely inert gases also meet the requirements for electrostatic properties. Finally, static electricity itself acts as a source of fire and can pose a hazard to the surrounding area
“\"High concentration of surrounding gas\" makes sense!
Our workplace also doesn’t have an electrostatic ground connection. Generally, liquid caustic is 30% concentration; not to mention static electricity, even a leak is no big deal. Personally, I don’t think it’s necessary.
