Why should medical gas cylinders not be placed in a confined space?

Medical gas cylinders should not be placed in a confined space primarily to prevent pressure buildup. When gas cylinders are stored in a confined area, any leakage or malfunction can lead to an accumulation of gas that could create an unsafe environment. Increased pressure in confined areas poses significant risks, including the potential for explosions or the displacement of oxygen needed for breathing.

Confined spaces can quickly become hazardous if gases leak, as they may not dissipate properly, leading to dangerous concentrations of gas. Therefore, ensuring adequate ventilation and preventing the placement of cylinders in these areas is essential for maintaining safety protocols in medical settings.

The other options, while they may seem relevant in certain contexts, do not directly address the critical safety concerns associated with pressure buildup in confined spaces.
