A hospital's building controls system monitors and operates the environmental equipment to maintain a safe and comfortable environment. Which of the following could be used to minimize the risk of utility supply interruption?
A.
Digital protection and control devices capable of minimizing the adverse impact to critical utility
B.
Standardized building controls system software with high connectivity to hospital networks
C.
Lock out maintenance personnel from the building controls system access that can impact critical utility supplies
D.
Digital devices that can turn equipment off and continuously cycle rapidly in order to increase supplies and conceal activity on the hospital network
A seems most correct out of the options. Hospitals rely heavily on continuous utility supplies (electricity, HVAC, water) to keep critical systems like life support, surgical equipment, and medication storage running. Any interruption could lead to life-threatening situations.
I'm thinking Uninterruptible Power Supply (UPS) is a subset of Digital protection and control devices, which in my mind make A correct, when protecting from utility supply interruptions like power loss and brown-outs.
It seems C is the best answer. The question asks about limiting utility supply interruption. Utilities are electrical, plumbing, hvac. Someone starts messing with a valve, breaks it, causes an outage. The Chernobyl reactor explosion happened during a scheduled test. I say don't let anyone access the utilities unless there is a valid reason, that would be the place to secure.
