Why are zone valves incorporated into a hospital's central gas piping systems?
1) To terminate O₂delivery to an area in case of fire
2) To allow selective maintenance without shutting the system down
3) To allow variable pressure reduction throughout the system

Question

Quizplus · Accepted Answer

Zone valves in a hospital's central gas piping systems are incorporated primarily for safety and maintenance reasons. They allow for the termination of gas delivery to specific areas in case of a fire (1) and enable selective maintenance or repairs without the need to shut down the entire system (2). Variable pressure reduction is not typically a function of zone valves; thus, option (3) is not a reason for their incorporation.
