Question: 1 / 400

What is the minimum height of a tower crane's safety zone?

10 feet or 3 meters above ground

15 feet or 4.5 meters above ground

The minimum height of a tower crane's safety zone is 15 feet or 4.5 meters above ground. This standard is established to ensure that the area around the crane operates safely, providing enough clearance to protect workers and bystanders from the potential hazards associated with crane operation and material movement.

Having a defined safety zone height helps to mitigate risks such as falling objects or inadvertent contact with personnel or equipment on the ground. This height reflects common operational practices that take into account the potential dangers posed by crane operations and the need for safety buffers.

Lower heights, like 10 feet, may not provide sufficient protection for walkways or working areas below the crane. Conversely, a higher requirement of 20 feet or 25 feet may not be practical for many job sites where clearance is already limited. Hence, the established minimum of 15 feet balances safety precautions with operational feasibility.
