Final answer:
It is true that establishing eye contact with equipment operators is a safety principle, and it is false that high-voltage wires are insulated. It is also true that lightning can travel through wood despite it being an insulator.
Step-by-step explanation:
The statement that establishing eye contact with your equipment operator is a general safety principle when working outside the working radius is true. It is crucial for ensuring safety on work sites, particularly when heavy machinery is in operation.
Regarding electrical safety, it is false that the high-voltage wires connected to tall metal-frame towers are wrapped in an insulating material. These wires are actually bare and are held aloft by insulating connectors to prevent the flow of electricity to unwanted paths.
When it comes to the nature of wood and its interaction with lightning, it is true that although wood is normally an insulator, lightning can travel through a tree to reach the Earth due to the extremely high voltage involved in a lightning strike, which can overcome the insulative properties of wood.
The statement, 'Establishing iContact with your equipment operator is a general safety principle when working outside the working radius,' is True.
When working outside the working radius, it is important to establish iContact, which means maintaining direct visual contact or communication with the equipment operator to ensure safety. This helps the equipment operator know your whereabouts and prevents accidents.
For example, when working on a construction site, if you are outside the working radius of a crane, maintaining iContact with the crane operator is vital to avoid any hazards and accidents.
