What type of inspections are part of a quality control program?

The correct answer highlights a specific activity associated with a quality control program, which ensures that materials and installation procedures meet required standards and specifications. X-ray inspections of piping and steel work are non-destructive testing methods used to identify flaws, such as cracks or voids, within materials. This type of inspection is crucial in industries like construction and manufacturing, as it assesses structural integrity and safety without causing damage to the components being analyzed.

While drafting project specifications, conducting environmental assessments, and analyzing employee performance are important aspects of overall project management and operational efficiency, they do not directly relate to the quality control processes that focus specifically on evaluating physical materials and constructions to ensure compliance with safety and quality standards. Therefore, non-destructive testing methods, like X-ray inspections, play a pivotal role in quality assurance by providing essential data about the condition of critical components.
