11. Atmospheric Testing Procedures
Initials: Steps:
_________ 1. Confirm the approved monitor has the correct sensors for the expected hazards and is approved for the task.
_________ 2. Verify the monitor is within the required calibration interval and bump tested per ESCO/Client requirements.
_________ 3. Inspect the monitor (case, display, alarms, inlet/filter, tubing/probe if used) and confirm battery level is sufficient.
_________ 4. In known clean air, power on and complete fresh-air setup/adjustment per approved monitor prompts.
_________ 5. Test the space atmosphere before entry (do not enter to test). Use remote sampling if needed.
_________ 6. Sample at multiple levels: top, middle, and bottom (and any low points/sumps or dead-air areas). Allow readings to stabilize at each level (longer when using tubing).
_________ 7. Confirm testing order is followed: 1) Oxygen (O-2), 2) Flammability (LEL), 3) Toxic gases (as applicable).
_________ 8. Acceptable entry conditions: O2 = 19.5% to 23.5%; LEL < 10%; toxic gases below applicable limits (OSHA PEL and any client/site limits).
_________ 9. If any alarm activates or readings exceed limits: stop work, evacuate/do not enter, and notify supervision. Do not re-enter until conditions are evaluated and controlled.
_________ 10. During entry, maintain continuous monitoring in the immediate work area as required by the hazard assessment/permit/checklist.
_________ 11. Document readings and required details (space ID/location, date/time, levels tested, results, monitor ID/serial or tool number, tester name/initials) on the applicable checklist/permit.
