Six Sigma Yellow Belt Foundational Skills Practice Test

The phase of 5S that emphasizes eliminating tripping hazards and ensuring supplies are marked is safety. This particular phase focuses on creating a safe work environment by identifying and addressing potential hazards that could cause injury or accidents. It involves organizing the workspace in a manner that reduces risks, such as ensuring that walkways are clear, tools and materials are properly stored, and any potential dangers are clearly marked.

Safety is crucial in the 5S methodology because an organized and clean workspace directly contributes to the well-being of employees. By actively working to minimize risks, organizations not only protect their workforce but also improve overall efficiency, as a safer environment leads to fewer interruptions and accidents. This mirrors the principles of Six Sigma, which aim for operational excellence by eliminating waste and ensuring quality outcomes in processes.

Other phases of 5S, such as setup, security, and satisfaction, do not specifically focus on the aspects of workplace safety and hazard identification, making safety the correct choice.
