What typically requires the use of a tag line when hoisted to the roof of a structure?

Using a tag line for a smoke ejector when hoisting it to the roof of a structure is important because it provides added control and safety during the lifting process. Smoke ejectors are necessary tools that help in ventilating smoke and heat from a building during a fire. These devices are often bulky and can be tricky to handle, especially in a high-stress environment like a fire scene.

The tag line helps in controlling the descent or ascent of the smoke ejector, allowing firefighters to reposition it as needed while maintaining safety and ensuring it lands securely and operates effectively. This control is crucial to prevent accidental drops or instability, which could cause damage or injury.

Other equipment, like fire hoses, respiratory equipment, or fire extinguishers, typically don’t require the same level of careful handling or positioning as smoke ejectors during hoisting. While all equipment needs to be managed properly, the added complexity and risk associated with smoke ejectors make the use of a tag line particularly beneficial in that scenario.
