What temperature range should medical gas tanks be kept within?

The correct answer indicates that medical gas tanks should be kept within a temperature range of -20°C to +50°C. This range is critical for maintaining the integrity and safety of the gas within the tanks.

When medical gas tanks are exposed to extreme temperatures outside this range, it can lead to significant pressure changes within the tank. As temperature increases, the pressure of gases generally increases as well, which can pose a risk of over-pressurization. Conversely, at lower temperatures, the pressure can decrease, potentially leading to challenges in gas delivery when needed. This makes it essential to operate within this specified range to maintain the stability of the gas and prevent any hazardous situations.

The other temperature ranges provided are either too restrictive or not wide enough to account for normal fluctuations that can occur in various environments where medical gases are stored and utilized. Keeping tanks outside the specified range could therefore compromise both the safety and effectiveness of the gases they contain.
