Before reversing any machinery, what should the operator do?

When preparing to reverse any machinery, it is crucial for the operator to prioritize safety by looking back over both shoulders and sounding the horn. This action helps ensure that the operator has a clear visual check of the area behind the machine, allowing them to identify any potential hazards or obstacles, including the presence of people or other equipment. The act of sounding the horn serves as an auditory warning to alert those nearby that the machinery is about to move, further enhancing safety.

Relying solely on mirrors, which can create blind spots or fail to provide a complete view of the surroundings, is not sufficient. Additionally, waiting for a signal from co-workers can introduce delays and may not be the most effective way to ensure safety prior to reversing. Revving the engine is an inappropriate signal and does not contribute to safe operation. Hence, the combination of visual checks and auditory warnings is the best practice before reversing machinery.
