What must all conveyor systems be equipped with as a time-delay warning system?

Conveyor systems must be equipped with audible and visual warnings as a time-delay warning system to enhance worker safety and awareness. These warnings serve to alert personnel of impending movements or actions of the conveyor, allowing them adequate time to react, thus reducing the risk of injury.

Audible warnings, like alarms or beeps, can catch the attention of workers in noisy environments, while visual indicators, such as flashing lights, provide a clear and immediate alert that the system is about to operate. Together, these signals ensure that workers are not only aware of the conveyor's status but also able to take appropriate safety measures. The combination of both types of warnings is vital in providing a comprehensive safety system that addresses different sensory needs.

This requirement underscores the importance of proactive safety measures in industrial environments, ensuring that all personnel are adequately prepared for movements that could pose risks if not properly communicated.
