What safety features are standard on gas cylinders to prevent high gas pressure?

1. Pressure regulators only

2. Rupture disks and emergency pressure relief valves

3. Manual shutoff valves

4. Temperature sensors

The correct answer is: Rupture disks and emergency pressure relief valves

The correct answer identifies rupture disks and emergency pressure relief valves as standard safety features on gas cylinders specifically designed to prevent high gas pressure. These devices serve crucial roles in maintaining safety in environments where gas cylinders are used. Rupture disks are designed to burst at a predetermined pressure, allowing gas to escape in a controlled manner if the internal pressure exceeds safe limits. This helps to prevent catastrophic failures or explosions that could result from excessive pressure buildup. Emergency pressure relief valves, on the other hand, automatically release gas when the pressure exceeds a certain threshold, providing another layer of safety. These valves help to ensure that the pressure inside the cylinder remains within safe operating limits, thereby protecting both the equipment and personnel nearby. While pressure regulators, manual shutoff valves, and temperature sensors are important components in gas handling and management systems, they do not directly prevent high gas pressure in the same way that rupture disks and pressure relief valves do. Regulators control the pressure output but do not prevent high internal pressure. Manual shutoff valves can halt gas flow, but they don't address the issue of pressure buildup within the cylinder itself. Temperature sensors monitor changes but do not act to relieve pressure directly. Therefore, rupture disks and emergency pressure relief valves are specifically designed as safety measures against
