In a situation where the survivor is entangled in a parachute, what method should the Rescue Swimmer avoid?

When a survivor is entangled in a parachute, the method to avoid is the underwater approach. This is because using an underwater approach can increase the risk of further entanglement or create a hazardous situation where the swimmer cannot effectively assist the survivor. Approaching the survivor from underwater might also impede visibility and the swimmer's ability to assess the situation fully, making it more difficult to perform a safe and effective rescue.

In contrast, a surface approach allows the swimmer to maintain a clear view of the survivor and the entanglement, ensuring better situational awareness and enabling the swimmer to communicate more effectively with the survivor. Typically, this method also enables the swimmer to employ techniques and tools more easily while keeping safety as a primary concern.

Direct rescue can be appropriate as it implies immediate engagement with the survivor, but this method must be performed cautiously to avoid worsening the entanglement. Quick intervention usually refers to acting rapidly to assist, which is important but should not compromise safety. Therefore, the most effective approach when dealing with a parachute entanglement would involve clear visibility and communication, which the surface method supports, making the underwater approach the one to avoid.
