How tight must installed boiler safety valve gags be?

• A. Finger-tight
• B. Hand-tight
• C. Wrench-tight
• D. Drill-tight

Answer: (B)

The installed boiler safety valve gags must be tightened to a hand-tight specification. This level of tightness ensures that the gags hold the valve in place securely while still allowing for easy removal when necessary. Safety valves are critical components in a boiler system, designed to relieve excess pressure and prevent potentially dangerous situations. Finger-tight would not provide sufficient security, potentially allowing for premature movement of the valve, while wrench-tight could be too tight, making the valve difficult to remove during maintenance or emergency situations. Drill-tight is not an appropriate standard for a safety valve, as it implies a level of tightness that could compromise the valve's ability to function properly or its removal. Hand-tight strikes the right balance between securing the valve and ensuring it remains operationally accessible when needed.
