Which feature is NOT commonly associated with trampoline safety practices?

Group jumping is not commonly associated with trampoline safety practices because it significantly increases the risk of injury. When multiple individuals jump on a trampoline simultaneously, the potential for collisions, falls, and improper landings rises dramatically. Safety guidelines typically recommend that only one person jump at a time to mitigate these risks, ensuring that each jumper has enough space to safely perform their actions without the danger of interfering with others.

On the other hand, strict supervision, height restrictions, and clear exit paths are all essential components of trampoline safety practices. Supervision is crucial to ensure that jumpers are using the trampoline safely and to intervene if necessary. Height restrictions help limit the risk of injuries resulting from high jumps or flips that can lead to falls. Clear exit paths ensure that jumpers can safely dismount the trampoline without obstruction, reducing the likelihood of accidents during the exit process.
