In this case there was no boat crew and certainly nobody else to blame. I disagree that this is always the case. I remember a dive where I geared up, checked my gear, breathed off my reg and saw one of the boat crew reach to check my tank. I told him my air was already on so to leave it. Unfortunately he managed to turn my air off then back on a 1/4 turn without me catching him at it. Must have been when I had my back to him waiting for the diver ahead of me to clear so I could splash. Breathed ok when I did the stride in then, I removed the reg while I waited for the rest to splash. Of course at 1/4 on it re-pressurized enough for me to get a couple normal breaths while I descended then got real hard to breath! Not impressed!
See above.. not always a guarantee. You gotta have eyes in the back of your head!
We all know what the only two guarantees in life are........
I have an overwhelming self preservation desire which drives me to ensure that I am the last one to tamper with my scuba gear before falling in. The people I dive with are mostly self reliant competent divers who know not to touch each others gear without asking first. If we do get an unknown quantity on board, we usually dispatch them over the side first so they are out of the equation.
Once I sit on the gunwhale, I check my reg and SPG is working ok by taking 4 breaths, flip down ( yes down ) my mask and fall in.......on the odd occasion I have to climb back on board to put my weight harness on.
