Hair entanglement can be a serious hazard when working with rotating tools or machinery in manufacturing facilities. Loose hair or clothing can easily become entangled in machinery, leading to severe injuries or even death. It's important for workers to always tie back their hair, remove loose jewelry or clothing, and follow all safety protocols when working with machinery to prevent hair entanglement accidents. By staying aware and taking appropriate safety measures, workers can avoid this dangerous hazard and stay safe on the job.
