What minimum distance must oxygen CMT (Central Medical Transmitter) be identified by the manufacturer?

The correct answer relates to the standard requirements outlined in NFPA 99 regarding the identification of medical gas systems. According to the NFPA 99 standards, the manufacturer must identify the Central Medical Transmitter (CMT) for oxygen at a minimum distance of 3 feet. This requirement serves multiple critical purposes, such as ensuring that healthcare personnel and first responders can easily locate and identify oxygen sources in emergency situations, thereby enhancing safety protocols in medical environments.

Establishing a clear distance for identification also helps to minimize the risk of accidental exposure to the gas and reinforces proper operational procedures for medical gas systems. The 3-foot identification distance strikes a balance between visibility and safety, facilitating efficient access while ensuring that oxygen sources are appropriately marked and recognized within medical facilities.
