The minimum clearance required for the temporary connection of the Emergency Oxygen Supply Cylinder (EOSC) is 3 feet. This requirement is in place to ensure safety and accessibility for medical gas systems. Adequate clearance is essential to facilitate maintenance, inspection, and emergency access while minimizing risks associated with the operation of oxygen supplies.

A clearance of 3 feet provides a balance between sufficient space for operations and ensuring that medical personnel can quickly and efficiently respond to situations where oxygen supply may be needed urgently. Having this space helps to prevent accidental bumps or disturbances to the equipment that could lead to leaks or other hazards.

In contrast, smaller clearances, such as 2 feet, would not provide adequate room for safe operation and could pose risks during emergencies or routine access to the equipment. Similarly, larger clearances (4 feet or 5 feet) are not necessary and could result in inefficient use of space in medical facilities, where every square foot is valuable. Thus, the requirement of 3 feet strikes an appropriate balance between safety and practicality, reinforcing the importance of adherence to established guidelines in medical gas practice.
