Walking under the rotating blades is a significant safety concern when approaching a helicopter. The rotating blades of the helicopter present an immediate and dangerous hazard to anyone who is beneath them. These blades can cause severe injury or even be fatal, as they can spin at high speeds and can be very low to the ground, particularly during landing or takeoff.

Awareness of this danger is crucial for anyone working around helicopters, as the blades are not only difficult to see due to their speed but also present a risk even if a person is not directly in the flight path. Proper protocols and guidelines dictate that individuals must avoid walking under or near the blades to ensure their safety while operating or being near a helicopter.

Understanding this risk emphasizes the importance of situational awareness and adherence to safety protocols when in the vicinity of aviation operations.
