What is the hazard of having too much pressure in a gas cylinder?

Having too much pressure in a gas cylinder poses a significant hazard because it can cause the cylinder to burst. Gas cylinders are designed to hold gases at specific pressures, and exceeding this pressure can compromise the structural integrity of the cylinder. When a cylinder bursts, it can release gas rapidly, which may lead to explosive reactions, projectiles, and serious injuries to anyone nearby. This explosion risk is critical in environments where gases are used, and proper handling and pressure monitoring are essential for safety.

Although other options mention issues related to gas delivery or flow, they do not capture the severe safety risk associated with over-pressurized cylinders. Ensuring that cylinders are maintained within their safe pressure limits is vital for preventing catastrophic failures and ensuring user safety in any setting where compressed gases are utilized.
