When changing elements, what should be done on the element itself?

• A. Record the date in the log
• B. The month and year should be stenciled on there
• C. Replace with new gaskets
• D. Calibrate the gauge

Answer: (B)

Labeling the replacement date directly on the element is essential for quick, at-a-glance tracking of service life. Stenciling the month and year on the element provides an immediate indicator of when it was installed, so inspections and future maintenance can be planned without digging through records. While keeping a maintenance log is important, the question focuses on what to put on the element itself. Other actions like recording the date in a log, replacing gaskets, or calibrating gauges are not actions to be performed on the element itself, and they serve different purposes.
