  • Module 10: Record Keeping & Datalogging
  • Conclusion

Course Outcomes:

Upon completion, students will have a basic understanding of:

  • What a DRI is and where it is used
  • How different types of DRIs function including Colorimetric (Detector) Tubes, Electrochemical Sensors, Oxygen Sensors, Combustible Gas Sensors, Photoionization Detectors (PIDs), and other specialized detectors
  • What a hazard evaluation is and why it is important to complete one before using a DRI
  • Chemical properties of gases and vapors and how that affects DRI measurements
  • How to identify the functions and limitations of your DRI, including cross-sensitivities
  • Calibration and functional tests
  • How to troubleshoot unusual readings
  • How to maintain a DRI
  • How to keep appropriate records of your DRI including data logs

    Why a Certificate Program?​

    A certificate program awards tangible proof that knowledge was achieved and/or skills mastered. ​

    Who Will Benefit

    This course will benefit any individuals who use DRIs to monitor work environments to protect worker health and safety. This may include firefighters, emergency workers, industrial workers, and entry-level OEHS professionals (such as IH Technicians).
