Dave walking the gas-test routine — same one we'd want done on our own crew. Bump test. Zero in clean air. Test top, middle, bottom of the space. Wait the full draw time. Record the readings. Then — and only then — enter. Watch the routine, copy the routine. It's that simple. What gas detector is your crew running? Comment the brand.
