Surge Suppressor and Hazardous Area

Surge Suppressor and Hazardous Area

Surge Suppressor and Hazardous Area

(OP)
Section of the Chemical Plant upto the 30 m is Hazardous Area. That Section is covered by enclosures, but not total enclosed. Potential gases inside are heavy gases. These gases go outside,making Hazardous Area all around the structure.(close to the ground level)
The structure is built more than 30m, upto 36m but this is an unclassified area. At that level - 36m, client want to install Telecommunication Antenna and Surge Suppressor connected on antenna cable.
I didn't have that case before,and I need articles and Standards what can help me.
Note: Potential lightning surge before reach the ground must go through the Hazardous Area.
Any Comment I welcome.
Thanks
