What must be done if safety valves are accidentally lifted during boiler hydrostatic testing?

• A. They should be replaced immediately
• B. They shall be tested to ensure proper operation
• C. They should be adjusted before testing
• D. They must be cleaned thoroughly

Answer: (B)

When safety valves are accidentally lifted during boiler hydrostatic testing, it is crucial to conduct a test to ensure their proper operation. Safety valves are vital components that prevent overpressure by automatically relieving steam or fluid when pressure exceeds a predetermined limit. If they have been lifted, this could indicate a malfunction or miscalibration, which could lead to failure during actual operation scenarios. Testing them after they have been accidentally lifted confirms whether they can still function correctly and ensure safety. This testing process may include checking for leaks, ensuring the valve closes completely after being lifted, and verifying that it opens at the correct pressure. This process is essential for maintaining the reliability and safety of the boiler system. The other options do not address the immediate need for verifying the safety of the valves post-incident. Replacing the valves immediately assumes a fault that may not exist, while adjusting them without testing could compromise their integrity. Cleaning may be necessary for maintenance but does not address the critical aspect of confirming operational reliability.
