Question 1 of 27070

If the engineer on watch has reason to doubt the accuracy of the water level showing in the boiler gauge glass, he should FIRST __________.

🔍 Key Concepts

• Boiler gauge glass function and purpose • Standard safety checks when an indicating device may be faulty • Risks of adding feedwater when actual level is uncertain

💭 Think About

• Ask yourself: what simple action can I take directly on the gauge glass assembly to test whether the indication is true or false? • Which option could be dangerous if the level is already very low or very high but the gauge is lying to you? • Which choice represents a quick, reversible test rather than changing plant conditions or equipment?

✅ Before You Answer

• Verify which action directly tests the gauge glass without changing boiler water level. • Eliminate options that add water before confirming the real level. • Consider normal engineering practice: first check the indicator, then change the plant only after confirming.
