The correct choice is orange because it is universally recognized as a color indicating caution or warning in various industries, including construction and hoisting operations. The use of an orange warning device enhances visibility and alerts personnel to potential hazards associated with the hoist line. The placement of this device at a distance of 8-10 feet above the rigging is strategic, ensuring that it is noticeable from a safe distance, allowing workers to maintain awareness of their surroundings and any overhead activities.

Additionally, the specific hue of orange is integral in conveying the message of caution effectively; it stands out against most backgrounds, making it easier for workers to identify potentially dangerous situations quickly. This practice is part of safety protocols aimed at preventing accidents and ensuring that all personnel can recognize when equipment is in operation or when the area is hazardous due to lifting activities.
