About Know Your Gas
A public language for gas checks and cylinder handoffs.
Know Your Gas exists to make good gas-awareness habits easier to understand, repeat, and share—without pretending that a slogan, label, or app can replace the diver.
Why this exists
Divers are not machines. Attention shifts. Routine creates expectations. Time pressure changes what gets noticed. Team dynamics influence which questions are asked out loud.
Know Your Gas gives that reality a simple public language: Analyze. Verify. Identify. The aim is not to declare people careless. It is to make useful checks and clearer handoffs easier to discuss.
Start with the question in front of you.
Each guide addresses a specific point between gas analysis and the moment a cylinder changes hands.
What was actually analyzed?
Separate the gas you expected from the gas that was measured, then review the information before it is carried forward.
What could make us miss something?
Notice how familiarity, time pressure, divided attention, and team dynamics can make an assumption feel settled.
Will the information stay with the right cylinder?
Keep reviewed information connected to the cylinder so the next person has something specific to read, question, and confirm.
What this website is not
It is not a training agency, certification, gas-analysis method, dive plan, or substitute for qualified instruction. It does not decide whether a gas is suitable for a dive.
Know Your Gas is an initiative by the makers of Scuba Tank Stickers. Scuba Tank Stickers is the first featured product, not the Know Your Gas brand itself. The app helps create and print labels from values a user has already analyzed and reviewed.
