Atmospheric Testing: Conducting, recording, and interpreting gas reading levels (oxygen, flammable gases, toxic vapours) using calibrated equipment before and during entry into confined spaces.

Hazard Identification: Identifying potential hazards and recommending control measures (such as forced ventilation) to ensure a safe environment.

Equipment Management: Ensuring proper selection, calibration, and maintenance of gas testing and monitoring equipment.

Permit-to-Work Procedures: Verifying that atmospheric conditions meet safety standards before the issuance of a work permit.

Continuous Monitoring: Performing real-time, continuous, or regular monitoring to ensure the space remains safe, and ordering evacuation if hazardous conditions develop.

Reporting: Documenting and maintaining accurate, real-time records of all gas test results.
