Can a Power Distribution Room Be Set up in an Explosion-Proof Area

Positioning distribution rooms within explosion-proof zones is not advisable, as it not only elevates investment outlay but also amplifies accident risks.

Per the “GB50160-2014 Building Fire Protection Design Standards”, Class A workshop areas are prohibited from hosting offices or distribution rooms. In cases where a dedicated distribution room is essential, it should be placed adjacent to a wall with an imperative for the dividing wall to be explosion-proof.

Control rooms, cabinet rooms, and electrical distribution and substations ought to be situated beyond the explosion hazard zones, ensuring ample safety margins. In these areas, the electrical equipment is exempt from explosion-proof requirements. This approach is widely adopted across the majority of chemical industry facilities today.
