What is indicated by the attachment of red tags on parts?

The attachment of red tags on parts signifies that these items are defective and should be scrapped. Red tags are a widely recognized visual management tool used in quality control processes. They alert personnel that the tagged components do not meet quality standards and therefore cannot be utilized in production processes or shipped to customers.

This practice is essential in maintaining quality assurance within a facility, as it prevents defective parts from entering the supply chain or being used in production, which could lead to further issues down the line, including customer dissatisfaction and increased costs related to rework or returns. The use of red tags is a critical aspect of effective quality management, ensuring that only acceptable and compliant materials are in circulation.
