Which document must be obtained before modifying an existing medical gas or vacuum system?

• A. A shutdown permit
• B. A service ticket
• C. A construction permit
• D. A safety clearance

Answer: (A)

In healthcare settings, making changes to an existing medical gas or vacuum system must be preceded by a formal shutdown permit. This document officially authorizes a temporary shutdown of the system, ensuring it is safely isolated so work can be done without gas flow, pressure hazards, or contamination risk. It also ties into the facility’s permit-to-work process, confirming that the area is prepared, personnel are notified, and verification steps are completed before the system is re-energized. A service ticket is just a service request, not a safety authorization; a construction permit covers new work or major renovations rather than modifying an existing system; a safety clearance is a general clearance, not the specific authorization needed to shut down and work on the system.
