Several considerations must be made before actively engaging in work with a lift truck. Which of the following is NOT one of them?

Answer: D — Using a non-approved safety harness

Using a non-approved safety harness is not an appropriate consideration because safety harnesses are intended to prevent falls and enhance safety when working at heights. Employing a non-approved harness undermines safety protocols and doesn't adhere to the established safety guidelines. As such, ensuring that only approved safety equipment is used is crucial for protecting workers. In contrast, the other considerations are vital for safe lift truck operation. Positioning the vehicle in the roadway must be done carefully to ensure that traffic is not obstructed and that safety risks are minimized. Establishing a temporary traffic control zone is essential for protecting both the workers and the public while the lift truck is in operation, as it delineates the work area and informs other motorists of potential hazards. Verification of overhead conflicts is critical to prevent accidents or damage caused by obstacles like power lines or other infrastructure that could pose a danger while the lift truck is in use. Each of these factors contributes to a safe working environment, highlighting the importance of adhering to safety regulations and protocols when operating lift trucks.
