If you skip the gas test, you're guessing with your lungs. Order matters in confined space entry: O₂ first (19.5–23.5%), then LEL (<10%), then toxics (CO, H₂S). Test from top to bottom. Re-test on entry. Re-test continuously. One reading is not a plan. What's the first gas you check? Comment your order.

First comment · Quick one: bump-test your detector every shift. Calibration is not the same thing.
