Final answer:
The given statement 'That the possibility of being burned increases when welding overhead position' is true due to increased exposure to hot metal and sparks. High-voltage wires are not wrapped in insulating material and are held up by insulating connectors, making the correct answer to the question false. So, the correct answer is A) True.
Step-by-step explanation:
True: The possibility of being burned increases greatly when welding in the overhead position. When welding overhead, gravity plays a role in bringing the hot metal and sparks closer to the welder's body and face, despite the protective gear like welder's gloves and helmet.
High-voltage wires are actually held aloft by insulating connectors, but these wires are not wrapped in insulating material due to various practical reasons like heat dissipation and the sheer size of the cables.
Types of work that may cause an increase in the radiation exposure of a worker include those where the worker is in proximity to sources of ionizing radiation such as X-rays or gamma rays, or work in nuclear power plants.
Thus, the correct answer is A) True.
