Final answer:
When insulation is falling into an open chase in a type B vent in an attic, it should be reported due to potential safety issues. High-voltage wires are indeed safely insulated for electrical safety, and while wood acts as an insulator, it can't stop lightning. Insulating material like fiberglass batt is used in buildings to prevent heat transfer.
Step-by-step explanation:
Yes, it's true that you should report the situation when you notice insulation falling into an open chase in a type B vent in an attic. The type B vent is designed to release combustion by-products from gas furnaces. Therefore, having insulation enter the open chase can lead to potential safety hazards as it might disturb the proper functioning of the vent or even pose a fire risk. In order to prevent such risks and ensure the safe operation of the vent, the falling insulation should be reported and the situation should be resolved by a professional.
Alluding to the additional information provided, it's also true that high-voltage wires are held aloft by insulating connectors and these wires are wrapped in an insulating material. This is essential to prevent electrical leaks and ensure safety. Furthermore, though wood is an insulator, lightning can indeed travel through a tree to reach Earth; and fiberglass batt is a common insulation material used in buildings to prevent heat transfer.
