At a school parking-lot carport, a pallet of glass modules sits 40 feet from the array on level asphalt. Each module weighs 51 pounds, and the site lift plan requires two people to handle any item over 40 pounds. The finished rail sits 7 feet 6 inches above the pavement, so installers need an appropriately rated scissor lift to work at rail height rather than set the module from the ground. Crew leads also require installers to pivot with their feet instead of twisting at the waist. Which handling method meets all three requirements for setting these modules?
Select an answer to reveal the explanation.
Short Explanation
Because each module weighs over 40 pounds, you need two installers to raise it to the scissor lift and set it from rail height. Like turning with a tray in your hands, you should pivot with your feet instead of twisting at the waist.
Full Explanation
The module weighs 51 pounds, exceeding the site lift plan’s 40-pound threshold, so two installers must handle it. Because the finished rail is 7 feet 6 inches above the pavement, they must use an appropriately rated scissor lift to reach rail height and set the module from the work platform, rather than trying to install it from the ground. Pivoting with their feet keeps the turn in the legs and avoids twisting the waist, meeting the crew leads’ handling instruction. Carrying the module to the rail and pressing it overhead uses two people but relies on an overhead lift from the ground instead of positioning the installers at rail height; it therefore fails the required work-position method. Having one installer set the module alone violates the two-person lift-plan requirement, even if that installer is on a scissor lift and stands square. Using two installers at rail height but twisting at the waist meets the crew-size and access requirements, yet fails the required body-mechanics approach. Exam caveat: a lift that reaches the rail is not automatically appropriate; it must also be rated for the task. Practical check: before raising the module, confirm the scissor lift’s rating and that the team, platform, and planned work position comply with the site lift plan.
