What should you avoid doing with your clothing while under the blades of a helicopter?

When working under the blades of a helicopter, it is crucial to avoid actions that may increase the risk of injury or create distractions. One of the primary concerns is the potential for loose clothing to get caught in the helicopter's rotor blades, which can be extremely dangerous.

Removing a jacket or vest could leave you with loose fabric that may become a hazard. As the fabric flaps and moves, it can create an unpredictable situation, especially in the strong winds generated by the helicopter's blades. This movement can pose a significant risk, not only to you but also to the safety of the helicopter operation and crew.

In contrast, wearing long sleeves and a cap generally provides protection and does not introduce the same level of risk since they are typically more fitted and less likely to become entangled. Adjusting your belt is less likely to cause danger if done cautiously, as it is typically a secure item and would not be subject to the same risks as a piece of loose clothing. The emphasis is on ensuring that all clothing remains secure and fitted while in the vicinity of helicopter operations to maintain a safe environment.
