Q. Design Equipment Rooms for plant?

Equipment for important safety systems and controls shall be located such that they can remain operational during the defined accidental events. Controls for safety systems shall be located where they are accessible and available for safe, simultaneous use during an emergency.

Where redundant safety equipment is used in meeting this, it shall not be vulnerable to the same accidental events as the main system.

The emergency, UPS systems, associated controls, etc. shall be self-contained and located such that they are not vulnerable to events that affect the main power supply.

Field control panels and energy or actuation sources for control equipment, pipeline and emergency shutdown (ESD) valves shall be protected from dimensioning accidental events such as fire, explosion and mechanical impact, to ensure emergency operation of the barrier as necessary.
