What is the purpose of a valve on a gas cylinder?

• A. To increase the gas volume
• B. To control the release of gas
• C. To filter impurities from the gas
• D. To prevent gas from escaping

Answer: (B)

The primary purpose of a valve on a gas cylinder is to control the release of gas. This functionality is crucial in various applications, including medical settings, where precise gas delivery is essential for patient care. The valve allows users to safely open or close the cylinder, regulating gas flow according to need, which can vary based on the medical equipment or treatment being utilized. When a user turns the valve, they can adjust how much gas is released at any given time. This control is vital for ensuring that the correct dosage of medical gas is administered, preventing both wastage and potential hazards that could arise from excessive or insufficient gas flow. While filtering impurities and preventing gas escape are important aspects of overall gas storage safety and integrity, they are not the primary functions of the valve itself. Additionally, increasing gas volume does not fall under the valve's purpose, as volume management is determined by the cylinder's capacity and the pressure within it, not by the valve operation.
