This PDC provides the knowledge and helps develop the skills needed to train field persons in the operation of Portable Gas Detection Instrumentation, focusing on delivering training to meet the body of knowledge requirements of the AIHA Registered Operator credential. At the end of this PDC, participants will be prepared to train users of the portable 4-Gas Meter and/or the combo 4-Gas Meter/Photoionization Detector (PID).

This PDC is not required to become registered and completion does not guarantee inclusion in the registry.

Value Added:

Post PDC, participants will be eligible to complete the proficiency exam and become REGISTERED USERS of the 4 Gas/PID.

Learning Aids:

Participants must bring a laptop.


Upon completion, the participant will be able to

  • Recognize sensor poisons.
  • Apply the O2 sensor as a broad band detector.
  • Explain the difference between calibrating to methane vs pentane and pentane vs. methane.
  • Develop a conceptual understanding of how each of the sensors work.
  • Cite what a front end technician needs to know about this instrument.
