The handhole refacing tool must only be used by what personnel?

The handhole refacing tool is a specialized piece of equipment used in the maintenance and repair of boilers and other pressure vessels. It requires skilled handling to ensure safety and effectiveness, as improper use can lead to equipment failure or personal injury. Therefore, it should only be operated by qualified personnel who have received specific training and have a solid understanding of the tool's mechanics and the operating procedures involved.

Qualified personnel typically possess a combination of experience, training, and knowledge regarding the proper techniques of using such tools. This ensures that they can both adhere to safety standards and maintain the integrity of the equipment being serviced. While apprentice machinists, engineering staff, and supervisors may have varying levels of expertise, the term “qualified personnel” is more precise in implying that the individual has the necessary credentials and experience specifically related to the use of the handhole refacing tool.
