I'm taking a look at the 2011 DAN Fatalities Proceedings document. Some lessons and conclusions (mostly copied) from it follow:
1. Pre dive is key:
Spend time in dive preparation.
Time spent in this area could have prevented 29 percent of the analyzable fatalities in the study. Dive preparation involves ensuring equipment is properly serviced, correctly prepared and properly fitted.
Conduct rigorous buddy checks; don’t let familiarity lead to cursory checks. A proper buddy check will need to ensure that all divers understand the dive plan and actions to take if things start to go wrong.
2. Honor the "Plan the dive, and follow the plan" mantra.
This means to regularly check gas supplies and take action early to avoid running low, don’t progress the dive into unplanned directions (in terms of depth, penetration, etc) and avoid becoming separated from your buddy.
Be alert to developing problems with yourself and your buddy, and be ready to act early and effectively. Practice the key diving skills, and keep this practice up-to-date. Good diving skills could have prevented or arrested 16 percent of the analyzable fatalities in this paper.
Stay well within your personal comfort zone, and be ready to call off or abort a dive if necessary. Do not adopt a brave stance and assume that the dive must go ahead. Awareness of this point could have prevented 9 percent of the analyzable fatalities in this paper.
3. As a diving professional you need to provide safety and advice:
From a dive operation perspective, buddy inexperienced divers with experienced divers and avoid “nonpair” diving. Also make sure you monitor the progress of a dive effectively. Care in this area could have prevented or arrested 18 percent of the analyzable fatalities in this paper.
Ensure that proper ascent rates can be achieved with ease. Ensure that divers are able to achieve surface buoyancy easily and quickly so they can secure themselves at the surface in an emergency situation. Have them practice out-of-gas procedures so they are second nature.
When diving with trainees or less experienced divers beware of this point from their perspective, and advice and guide them accordingly.
4. You need to know where you stand today:
Build up your experience gradually, progressing to more challenging environments at an acceptable pace and in the company of more experienced divers. Be prepared to rebuild this experience after a layoff from diving.
Do not assume that you can start from where you left off.
