Active shoulder engagement is often lost as the athlete tires, causing sheer force along the top of the spine, forcing the weight away from the frontal plane (the center-most line of the body), and making a load seem much heavier that it really is, which in turn, causes form to degrade even more. This is a vicious cycle that is hard to break, and why we must focus on this even when training with PVC pipes. Take a look at the photo below for an example of a CrossFitter losing active engagement due to fatigue.

See how his shoulders are not rolled, lats are not engaged, and generally the weight is pulling him downwards to the floor... arching his upper spine in the process. This is dangerous at heavy weights, and care should be taken to avoid this at all costs.
When performing a movement such as the deadlift, ensure you have proper spinal alignment, engagement of the shoulders, and full core tension. Squeeze your shoulder blades together and pull the weight against your body as you raise the bar from the floor. Keeping your shoulders as upright as possible throughout the entire movement.
See photo below, noting the alignment of the back.
