Kentucky Boiler Practice Exam

When are original mill material markings verified in the inspection process?

1. Only during the initial setup

2. At the time of inspection

3. When the boiler is first tested

4. They are not verified

The correct answer is: At the time of inspection

The verification of original mill material markings occurs at the time of inspection. This is a critical step in the inspection process because it ensures that the materials used in the construction of the boiler meet the required specifications and standards. During this inspection, inspectors will check the markings against the documentation to confirm the quality and compliance of the materials with relevant codes. This verification is essential for maintaining safety and reliability in boiler operation, as improperly sourced materials could lead to failures or safety hazards. By confirming the original mill markings, inspectors help assure that the materials are appropriate for the service conditions the boiler will face.
