Quality Control
Quality Control in quarrying involves checking and maintaining the standards of extracted materials like stone, gravel, or minerals. It's similar to having a safety inspector, but for materials instead of safety. People in these roles make sure that the rocks and minerals coming from the quarry meet customer requirements for size, shape, and purity. They do this by taking samples, running tests, and keeping detailed records. This role is essential because construction companies, manufacturers, and other customers need materials that consistently meet their specifications.
