What must persons do before getting on or off self-propelled mobile equipment when the operator is present?

Before getting on or off self-propelled mobile equipment when the operator is present, it is crucial for individuals to notify the operator. This step is vital for ensuring safety as the operator may not be aware that someone is about to board or disembark from the equipment. By informing the operator, they can take necessary precautions or stop the equipment if needed, minimizing the risk of accidents or injuries.

This practice is rooted in the principle of communication and teamwork in hazardous environments, where awareness of personnel movements around machinery can prevent dangerous situations. The operator's explicit acknowledgment of the situation contributes to a safer workplace by ensuring that both the operator and the individual are aligned regarding what is happening around the equipment at that moment.
