The control room is located in an explosion-proof area; what should be done with the control cabinets? Can it be made into a positive-pressure fume hood? It is in Zone 2, and the hazardous substance is dichloroethane
The regulations state that control rooms are not allowed to be located in explosion-proof areas
When the control room of the unit is located within the unit itself, it should be placed on one side of the unit and outside the area at risk of explosion； When the equipment located in the on-line analysis instrument room in an area prone to explosions is not explosion-proof, the on-line analysis instrument room shall be kept under positive pressure ventilation
But according to building codes, it seems that the control room is allowed to be adjacent to Class A and B factories; such a location is definitely within an explosion-proof area. Moreover, the building codes do not require it to be located outside such an area

They are just adjacent to each other, separated by an explosion-proof wall in between. Not in the explosion-proof area.
Should it be separated by an explosion-proof wall or a fire wall? What’s the difference between the two? If it’s separated, is it no longer in the explosion-proof area? Why
I remember it can be made to operate under positive pressure, and there are special wiring methods； Or simply make it an explosion-proof control column.
