Answer :
Final answer:
All pressure vessels must have a pressure relief valve or pressure-limiting device to prevent overpressure and ensure safety.
Explanation:
All pressure vessels shall be protected with a pressure relief valve or pressure-limiting device. Pressure vessels are containers used to hold fluids or gases at a pressure that is different from the ambient pressure. The purpose of the relief valve or pressure-limiting device is to prevent overpressure in the vessel, which could lead to a catastrophic failure. These safety devices are designed to automatically release excess pressure and maintain the pressure within safe limits.
