New York Low Pressure Boiler COF Practice

During a hydrostatic test, safety valves should be ____ or held by a ____.

1. Installed; regular clamp

2. Removed; approved clamp

3. Adjusted; safety lock

4. Inspected; installation rail

The correct answer is: Removed; approved clamp

During a hydrostatic test, safety valves need to be removed or held in place by an approved clamp to ensure that they do not activate during the test. This is essential because the hydrostatic test involves pressurizing the boiler to check for leaks and integrity under conditions that can potentially cause valves to open if they were left installed. Using an approved clamp to secure the safety valves prevents accidental discharge or activation, ensuring that the testing can be performed without interruptions or inaccurate readings. This practice aligns with safety protocols that protect both the equipment undergoing testing and the personnel conducting the test, which is crucial in maintaining safe operation in any boiler system.
