Based on several conversations with Divers concerned about getting wrapped up in legal action resulting from posts on SB, I have been able to piece together a probable sequence of events leading to the fatality. Again, this is not factual but a theory based on conversations, as well as overheard events, and 3rd party knowledge well as older posts in this thread.
The Instructor and 6 students began OWD 3 around 1100a. The instructor did not have a CA with him. The Instructor took the 6 students to the Memorial Platform (vis 25-30ft) to conduct OWD 3 skills. Once completed with the skills, the Instructor took the students on a tour, to include a dive to 50+ ft along the wall of the Quary. While deep the diver paniced, attempted to swim to the surface, and suffered a lung embolism, Once completed with the deep part of the tour the Instructor accended to the top of the wall (30 ft) and lead the group to a point roughly 200 ft from the wall. The Instructor and students conducted a 3 min safety stop and accended. Once on the Surface, at aproximatly 1125a-1130a the buddy of the victim informed the Instructor that his buddy was missing.
A search called for at approximately 1200p after the divers on shore were informed a diver was missing,
The search began at approx 1210p, the victim was recovered at approx 1215p and on the dock at 1220p
I contend that the Victim never completed the deep part of the dive, based on where she was located. The Instructor lost count of his students in the darker poor viz deep water and never confirmed the student count until either at the safety stop or on the surface. This is supported by diver statements and the fact PADI moved fairly quickly to expell the Instructor. Which, based on the website
"Expulsion only results after a PADI Dive Shop or Resort refuses to implement corrective measures, or when the nature of the complaint is so severe that expulsion is necessary to protect the public or to preserve the reputation of the PADI organization."
Divers have stated this instructor leads training dives from a "in the front single file line" position. Based on the vis the instructor couldn't have seen the last diver in the group. It was also overheard that a buddy team saw the class returning from the platform in this formation, as well as noting a single diver way behind the group trying to catchup.
I speculate that:
1. The diver was stressing about heading deeper to colder water and began breathing faster and shallower
2. Once the Diver got to 50ft the cold water (54-58 degrees) caused the diver to continue to breath faster and the diver became more stressed
3. with the poor viz (possibly as little as 4ft) the diver not being able to see her buddy, paniced, spit out the reg, and attempted to swim to
the surface, suffered a lung embolism, couldn't reach the surface and drown, having not inflated her BCD she dropped back down.
4. the Instructor assumed everyone was following along with the plan, and having lead possibly hundreds of training dives this way becamecomplacent to the risks of diving with students who have less than an hour in open water and roughly 3 hours acually in a pool breathing through a regulator.
If this theory is correct, or even close to the facts of the fatality, While its easy to simply write this up as "Instructor Error" and move on to the next thread, I have taken several learning points from this:
1. Never lose sight of your students
2. Always evaluate the conditions of the Dive site, plan the training dive based on teaching objectives (is there a need to go to 50ft?)
3. Use a CA if the class size and conditions warrant
4. You can be within standards but out of good judgement you gotta be within both.
5. Never delay calling for assistance when a diver is missing, swallow your ego and get assistance fast.
6. No matter how long you've instructed, how many times you've training students in the same dive site, or how many certs you have,
complacency is waiting around the corner ready to bite you in the ass.
I'm sure other, more senior, instructors and divemasters can add to or disagree with the ones I've listed above.
