    At the job site, the aerial lift device should be positioned so the work area is always

    • Directly over the truck

    • Within reach of the boom

    • In front of the truck

    • To the right side of the operator

    Correct Answer
    A. Within reach of the boom
    Explanation
    The aerial lift device should be positioned within reach of the boom in order to ensure that the work area can be easily accessed and worked on. This positioning allows the operator to extend and retract the boom as needed, without having to reposition the entire device. It also ensures that the operator can safely and efficiently perform tasks in the work area, without any obstructions or limitations. Placing the work area directly over the truck, in front of the truck, or to the right side of the operator may not provide the same level of accessibility and flexibility as positioning it within reach of the boom.

    When leather cannot be made soft and pliable enough by saddle-soap dressing, it should be

    • Oiled

    • Discarded

    • Weight tested

    • Inspected for dry rot

    Correct Answer
    A. Oiled
    Explanation
    When leather cannot be made soft and pliable enough by saddle-soap dressing, it should be oiled. Oiling leather helps to restore its flexibility and make it more supple.
