Final answer:
The statement about slings is false as slings do have general requirements for their safe use. The statement about high-voltage wires being wrapped in insulating material is also false, as they typically are not insulated due to their height and air acting as the insulator.
Step-by-step explanation:
The statement that general requirements do not apply to slings used in conjunction with other material handling equipment for the movement of material by hoisting is false. Slings are subjected to various regulations and standards to ensure safety and efficiency during hoisting operations. These general requirements would typically include the proper selection, inspection, maintenance, and use of the slings to prevent accidents and ensure that they are suitable for the loads they will carry.
By contrast, another true or false question presented is regarding high-voltage wires. The high-voltage wires that are connected to metal-frame towers being held aloft by insulating connectors and wrapped in an insulating material is false. These wires are typically not covered with insulating material because they are high above the ground, where the chance of unintended contact is very low, and the air itself acts as insulation.
