How should emergency shutoff valves be identified?

Emergency shutoff valves should be identified by a durable sign that is clearly visible near the valve. This approach ensures that the sign can withstand various environmental conditions and remain legible in emergencies. A clearly visible sign allows personnel to quickly locate and operate the valve during a crisis, which is crucial for safety and effective emergency response.

Using a durable sign also facilitates compliance with relevant safety standards and regulations concerning medical gas systems, as proper identification is vital for preventing accidental misuse or delays in response during emergencies. Options involving temporary or less reliable methods like tape markers or lights do not provide the same level of assurance that healthcare personnel can quickly and accurately identify emergency shutoff valves when time is of the essence.
