Thought: Check out NFPA 99, 2018 sections 5.1.13.5 and then 5.1.5.13:
5.1.13.5 as you know addresses the outlets for Instrument Air and Nitrogen support medical gases. This section refers to many other sections in 5.1.5 including 5.1.5.13 where it states the outlet (that is the function a nitrogen or instrument air control panel performs) SHALL be protected from damage.
This applies for two reasons:
1. When the end user control panel is in use the majority of the time the delivery device attached directly to the control panel is a nitrogen/instrument air hose directing the gas to the operating table area for the surgeon's use.
a. If the Surgery uses a Schrader QC coupler it usually sticks out even
further than the DISS/hose connection.
2. The majority of the time the Surgical Staff almost NEVER disconnects the hoses from the nitrogen/instrument air control panel. The door will hit the hose/outlet connection when opened
In taking both reasons into consideration, the door could damage the hose/outlet connection of the internal connections within the control panel if the door is swung open with too much force.
Two suggested plan of actions:
Either move the control panel (very expensive) or install a floor or wall mounted door stop to protect the hose/CP connection when the door is opened.
