What must be done to alert people when starting machinery?

When starting machinery, it is crucial to ensure the safety of everyone in the vicinity. Giving signals to alert everyone is a standard safety practice designed to prevent accidents and ensure that all personnel are aware of the machinery's operation. This can involve a variety of methods, such as hand signals, auditory signals (like whistles or alarms), or visual signals (such as lights) to make sure that workers know the machinery is about to start.

Using such alerts allows individuals to prepare for potential hazards associated with machinery operation, such as loud noises, moving parts, or changes in the work environment. By actively communicating that machinery is about to be engaged, the likelihood of accidents can be significantly reduced, creating a safer workplace.

In contrast, believing that no action is needed, relying solely on automated systems, or assuming that everyone is aware are all inadequate approaches. They do not prioritize the active and clear communication necessary to ensure safety in a dynamic work environment where multiple workers might be engaged in different tasks.
