Which of the following is NOT recommended when excavating?

Using equipment without safety measures is not recommended when excavating because safety measures are crucial for the protection of the operator and those nearby. Safety measures can include features like seat belts, guards, and proper operational protocols that minimize the risk of accidents. The absence of these safety features significantly increases the likelihood of injuries or accidents during excavation work.

Other options are all aligned with safe excavation practices. Checking machine stability ensures that the equipment is secure and lessens the risk of tipping or accidents. Staying aware of surroundings helps operators anticipate any potential hazards or changes in their environment, which is essential for maintaining safety on the job site. Removing obstacles from the trench is part of maintaining a safe working area, as it prevents potential tripping hazards and allows for more efficient operation of the machinery.
