What is typically required for vessels above 10 ft³?

For vessels with a capacity exceeding 10 cubic feet, the requirement for dual safety devices is in place to ensure enhanced safety and reliability. This standard is significant because larger vessels can contain more pressurized fluids and, consequently, pose greater risks in the event of a failure. The implementation of dual safety devices serves as a redundancy measure, providing an additional layer of protection against the potential for overpressure incidents.

In practice, this means that if one safety device were to fail or become inoperative, the second device would still be available to mitigate any hazardous conditions, thereby reducing the likelihood of a catastrophic failure. This requirement aligns with safety regulations and best practices in industrial settings, where managing risks associated with high-pressure systems is of utmost importance.

Other options do not align with the standard safety practices concerning pressure vessels of this size. While pressure release valves may be necessary in some scenarios, having dual safeties specifically addresses the higher risk profile of larger vessels. Single safety devices may not provide adequate protection, and suggesting that there are no specific requirements overlooks the crucial safety considerations for larger pressure vessels.
