Welcome to our Authorised Gas Tester elearning course where you will learn what gas testing is and about the different types of flammable and toxic gases, their behaviours, and hazards. You will also learn about the roles and responsibilities relating to authorised gas testing; how to prepare for gas testing; how to safely carry out gas testing and gas monitoring; and how to interpret the results.

Learning outcomes are shown below:

Module 1
LO1 Explain what gas testing is
LO2 Explain the locations or activities that might require flammable or toxic gas testing and monitoring
LO3 Outline roles and responsibilities relating to authorised gas testing

Module 2
LO4 Identify hazards and risks that may be found in enclosed spaces
LO5 Describe the different types of flammable and toxic gases, their behaviours and hazards
LO6 Describe how to implement safe systems of work in enclosed spaces or in areas where hazardous gases may be present

Module 3
