Operating Hydrogen Bromide Gas Detector:

Power On:

  • Turn on GAO Tek detector and allow it to go through its startup sequence. This typically involves a self-test to ensure all systems are functioning correctly.

Zero Calibration:

  • Ensure the detector is in clean air and perform a zero calibration if required. This sets the baseline for clean air with no HBr present.

Functional Check:

  • Conduct a bump test using a known concentration of HBr gas to ensure the detector responds correctly.

Regular Monitoring:

  • Use the detector to monitor HBr levels. This may involve carrying it on your person in a portable format or installing it in a fixed location for area monitoring.

 

Maintaining a Hydrogen Bromide Gas Detector:

Regular Inspection:

  • Check the physical condition of the detector regularly for any signs of damage or wear.

Sensor Check:

  • Inspect the sensor and replace it if it is expired, damaged, or showing signs of drift.

Battery Maintenance:

  • Regularly check and charge or replace batteries as needed.

Cleaning:

  • Keep the detector clean, particularly the sensor area, to avoid false readings or damage.

Record Keeping:

  • Maintain logs of inspections, maintenance activities, and any incidents of exposure.

 

Calibrating a Hydrogen Bromide Gas Detector:

Frequency of Calibration:

  • Follow GAO Tek’s recommendations for calibration frequency. This might be before each use, daily, weekly, or monthly.

Zero Calibration:

  • In clean air, adjust the detector so that it reads zero in the absence of HBr.

Span Calibration:

  • Expose the detector to a known concentration of HBr gas. This should be done using a calibration gas cylinder with a concentration within the range of the detector’s sensitivity.

Adjustment:

  • Adjust the detector’s response to match the known concentration of the calibration gas.

Verification:

  • After calibration, perform another bump test to verify accuracy.

Training:

  • Ensure all users are adequately trained in the use of the HBr detector.

Safety Gear:

  • Use appropriate personal protective equipment (PPE) when handling HBr gas or calibration gas.

Ventilation:

  • Ensure adequate ventilation when calibrating or bump testing the detector.

Documentation:

  • Keep records of all calibrations and maintenance activities.
