What is one way to prevent a dual deployment?

Initiating malfunction procedures at a high enough altitude to safely cut away from the main parachute is critical in preventing a dual deployment. When a malfunction is identified, the skydiver must respond quickly and efficiently. By maintaining a sufficient altitude, typically above the minimum deployment altitude, the skydiver can ensure that there is enough time to safely cut away the main parachute and allow the reserve parachute to deploy without complications. This action minimizes the risk of both parachutes being deployed simultaneously, which could lead to entanglement and significantly increases the risk of a dangerous situation.

Other options may seem plausible but do not effectively prevent dual deployment. For example, cutting away from the main parachute at any altitude may lead to a situation where there is not enough time for safe deployment of the reserve. Ensuring the RSL (Reserve Static Line) is always connected is a safety measure but could also inadvertently cause a dual deployment under specific circumstances, especially if a malfunction occurs with the main. Lastly, not using a reserve parachute is never a safe or advisable choice, as it completely eliminates the backup option necessary for a safe landing in case of a main parachute failure.
