Most diving safety is not dramatic. It is a collection of ordinary habits repeated until they become difficult to forget: checking gas, agreeing the plan, watching conditions, staying aware of the team and being willing to end a dive before a small problem becomes a bigger one.
Plan the dive you are actually doing
A plan does not need to be complicated, but it should answer the useful questions: where are we going, how deep, what gas do we have, when do we turn, where do we exit, what are the important hazards and what will make us call the dive?
Conditions can change the plan. The fact that a route worked yesterday does not make it correct today.
Know your gas before it becomes urgent
Gas awareness should be continuous, not a surprise check near the end. I want to know what I started with, what I am using and whether the pressure makes sense for where I am in the dive. A pressure gauge or transmitter gives a number; the diver still has to interpret it.
The team is part of the safety system
For normal recreational diving, the buddy system remains one of the basic layers of safety. Staying close enough to help, communicating clearly and noticing when another diver is becoming stressed matter much more than simply entering the water in pairs.
There are forms of self-reliant or solo diving with specific training and procedures, but that is a separate discipline. It should not be confused with two buddies gradually losing each other because neither was paying attention.
Equipment checks are boring for a reason
Leaks, valves that are not fully open, badly routed hoses, loose weights and forgotten accessories are easier to fix before entry. Familiar equipment can actually encourage complacency because we stop looking at it properly.
Control the ascent
Depth, ascent rate, decompression status and gas still need attention when the interesting part of the dive is finished. I use a safety stop as a routine part of recreational dives when conditions allow, but the whole ascent matters, not only the last few minutes at five metres.
Know when to stop
A dive can be cancelled for poor visibility, current, equipment, health, stress, lost gas margin or simply because something does not feel right. There is no prize for forcing the original plan to survive every change.
The sea will still be there. The useful habit is returning with enough margin to choose the next dive as well.
