Final answer:
Fall protection is essential when working on construction sites above specific height limits. It is false that high-voltage wires are wrapped in insulating material; they are held by insulators and the air gap prevents electrical discharge.
Step-by-step explanation:
The original question posed is regarding fall protection which is a subject within the realm of safety requirements and engineering practices associated with construction work. To clarify the statement in the question, fall protection must indeed be worn when placing or tying reinforcing steel above certain heights. This is to ensure the safety of workers on construction sites, where they are at risk of falls from elevation, which can lead to serious injuries or fatalities.
Turning to the reference information provided about high-voltage wires, the statement is false. High-voltage wires are indeed held aloft by insulating connectors to prevent electricity from traveling down the poles to the ground. However, these wires are not typically wrapped in insulating material; instead, they are bare and rely on the air gap and the insulating properties of the connectors to prevent electrical discharge.
