How should electrical equipment in explosion-proof workshops be effectively grounded? ? ?
Thread Content
I work in a workshop dedicated to cleaning chemical waste packaging drums. The equipment purchased for cleaning these drums is of Ex BT4 explosion-proof rating, and it does not require any special foundation for installation. The workshop itself is classified as a Class I explosion-proof area. May I ask whether equipotential static grounding should be achieved using hot-dip galvanized flat steel connected to the static wiring plates? Should it be buried with grooves dug in advance or laid openly on the ground? Urgent! It is currently under construction. I don’t have any knowledge of electrical systems, so I hope everyone can give me some advice! ! !
Static grounding is achieved by connecting the static wiring plate with hot-dip galvanized flat steel.
Bury it before laying the ground, and then use galvanized flat steel to lead it to the equipment that needs to be grounded.
Is it grooving and embedding? If I want to achieve this on the ground, what materials can be used as a substitute for flat iron? Since it’s a new factory, many more pieces of equipment will be added in the future
The key point is that equipment will continue to be installed, both now and in the future; I can’t determine in advance where the equipment will be placed, and the floor must be covered with epoxy coating. So, is there any way to apply it topically? Now the design institute does not provide installation drawings; when asked, the manufacturer only offers installation assistance without helping with positioning. Ah! Sorrowful Ah
This workshop needs an epoxy floor, so it has to be dug now; but since several cleaning lines will be installed later, I’m not able to determine their locations yet. I can’t just wait until the equipment arrives at the factory before digging up the ground. Is there an alternative, friend?
It’s best to dig grooves and embed components now, including in areas where there are no devices at the moment; this will help avoid problems in the future. If there are any changes in the reserved equipment locations in the future, extensions can be made on the ground.

Okay. It seems there’s no alternative
We don’t have a process package, and the design institute will simply use the manufacturer’s drawings to determine the installation locations. The issue is that the manufacturer has already specified some of the equipment; it’s not clear how many more items will be added later on
