Red Seal Heavy Equipment Operator (Excavator) Practice Exam

What should be done if an excavator begins to tip over during operation?

1. Quickly jump out of the cab.

2. Shut off the machine immediately.

3. Stay in the cab and maintain control to prevent a complete tip.

4. Call for help and wait for instructions.

The correct answer is: Stay in the cab and maintain control to prevent a complete tip.

When an excavator begins to tip over, the safest and most effective action is to stay in the cab and maintain control to prevent a complete tip. This approach is crucial because the operator is likely to have the most awareness of the machine's movements and the ability to potentially correct or minimize the tipping. By staying in the cab, the operator can also use the machine's controls to lower the bucket or boom, which can help stabilize the machine and lower its center of gravity. Jumping out of the cab can be extremely dangerous as it exposes the operator to the risk of being struck by the excavator or the ground as it tips. Shutting off the machine immediately may not allow the operator to address the situation effectively, as stopping the machine suddenly could exacerbate the tipping motion. While calling for help may be necessary once the immediate threat is managed, it is not the most effective first response during a tipping incident. Thus, maintaining control from inside the cab is the optimal choice to safeguard both the operator and the machinery.
