What is the fire hazard category for the substation in the sewage treatment plant? Are there any distance requirements regarding adjacent substations, automatic control rooms, sludge dewatering rooms, etc.? Can the substation be built together with distribution rooms, automatic control rooms, sludge dewatering rooms, chemical dosing rooms, and so on? Looking forward to your advice!
Petrochemical Regulations, versions 2008 and 2018: Substations are considered category II important facilities throughout the plant; a fire in them can affect production. Wet-type transformers fall under category C. There is usually a wall separating them from the power distribution rooms, while there are no fire protection requirements regarding the distance to the control rooms. It is necessary to check the design requirements for the instrument rooms as well as the requirements related to electromagnetic interference. The sludge dewatering rooms should be classified as category E, with no specific requirements for them. As for the chemical dosing rooms, it is important to determine what chemicals are used there and whether any explosive gases or liquids might be present. It is also necessary to identify the fire hazard category associated with these areas
