Which of the following is a visual indicator used to help locate powerlines?

Tiger Tails are a visual indicator specifically designed to help locate powerlines. They are brightly colored, typically made from a durable plastic, and are suspended from the powerlines themselves. Their vivid color and long, trailing shape make them easily visible from a distance, aiding both workers and the public in recognizing the presence of overhead powerlines. This is particularly important for safety, as it helps prevent accidents that could occur from inadvertently coming too close to live wires, especially when operating heavy machinery or during construction work.

Road cones, safety flags, and electrical tape may serve various safety purposes, but they are not specifically utilized to indicate the presence of powerlines. Road cones are generally used to guide traffic or mark hazards on the ground, safety flags are often used in different contexts to signify warnings or directions, and electrical tape serves a functional purpose in insulating or securing electrical connections but does not provide a visible warning for aerial hazards like powerlines. Thus, Tiger Tails stand out as the designated safety indicator that's recognized for their role in powerline awareness.
