In explosion-proof and corrosion-resistant environments, should grounding main lines and branch lines be installed exposed or concealed?

In an explosion-proof and corrosion-resistant environment, is it better to install the equipment’s main and branch grounding conductors (hot-dip galvanized flat steel) exposed or concealed?
The main grounding conductor should normally be underground, from where branches lead to the equipment; the equipment is then connected to these branches using flexible copper wires.
You can consider copper-clad steel here; if you need the technical specifications, I can send them to you!
In which corrosion environments is it not recommended to use exposed installation if flammable gases are generated as a result of the corrosion reaction?
