Question 7 of 8

7. Question
No hot water is reaching the main operating room (OR). What should be the first course of action in this scenario?
- Starting at the mechanical room serving the OR, verify the water heater is operating correctly and ensure adequate steam or voltage for system operation. Finally, check for safety switch issues and operation.
- Shut down the OR to prevent cases from being performed. Ensure the valves serving the OR are open and determine if hot water is reaching areas adjacent to the OR. Finally, verify the water heater is operating correctly.
- Notify the head of the surgical department. Then, inspect the thermocouples and heating element on the water heater. Finally, check the associated electrical breaker.
- Determine if service work was recently performed in this area. Then, inspect the building automation system (BAS) sensors to determine if the failure is technology-based. If not, then use a thermal imaging camera to confirm the exiting pipe from the water heater is reaching minimum temperature requirements. Then, ensure adequate steam or voltage for system operation. Finally, check for safety switch issues and operation.
