The key to avoiding injury is to keep your abdominals and glutes tight. It is physically impossible to hurt your lower back while those two muscle groups are engaged.

I would also work on making sure you've got the mechanics down for cleans and snatches without flopping the kettlebell onto the back of your wrist. The proper motion will have near zero force of impact.
