What is the safety zone distance for helicopters at incidents?

Protecting personnel from rotor wash, debris, and potential blade hazards is the key idea behind helicopter safety zones. Because the rotor downwash can extend far from the aircraft—depending on rotor size, wind, and load operations—a large, clearly marked perimeter is needed to keep people clear of dangerous air and objects during approach, landing, or hover operations. Establishing a safety zone roughly the length of a football field, about 300 feet, gives responders enough buffer to avoid injury while still enabling timely incident work. Smaller distances, like 100 or 50 feet, would put people in the rotor wash or near the tail rotor and blades, increasing risk. A much larger zone, such as 600 feet, would be unnecessarily restrictive and hinder operations.
