Level 1 materials must be closely tracked and controlled by which entity?

Level 1 materials refer to materials that are critical to the safety, quality, and performance of engineering projects. These materials must be closely tracked and controlled to ensure compliance with industry standards and regulations. The correct entity responsible for this control is the Control Material Purchase Order (CMPO), as it manages the procurement process and ensures that the specifications for Level 1 materials are met from the outset.

By utilizing a CMPO, organizations can maintain a comprehensive database that tracks the origin, quality, and status of these critical materials throughout the project lifecycle. This helps to ensure that all aspects of material handling, from purchase to installation, comply with the necessary quality assurance protocols.

The other options involve roles that contribute to quality assurance or execution but do not specifically mandate the tracking and controlling of Level 1 materials in the way that a CMPO does. The Quality Assurance Inspector and Quality Assurance Officer are primarily responsible for overseeing compliance and quality checks, whereas craftsmen focus on the actual work and implementation of materials rather than their procurement and control. Thus, the CMPO serves as the central mechanism for managing and tracking Level 1 materials effectively.
