The authorised gas tester (AGT) role is critical in testing for and ensuring safe working atmospheres, in particular: permit controlled confined spaces, and prior to and during hot work. The tasks authorised gas testers are required to undertake may vary depending on the workplace operation at the time. The tasks also vary in complexity and responsibility. Therefore, the AGT role has been split into three levels, they are: AGT Level 1, AGT Level 2 and AGT Level 3.

AGT Level 1 is required for those involved with performing a test for oxygen, flammable and toxic gases up to and including working in confined spaces. Persons undertaking Standby/Safety Watch duties at the entrance to a confined space shall be an AGT Level 1 Gas Tester.

Course Objectives

The aim and objectives of the AGT Level 1 training programme is to ensure that personnel preparing for a gas tester role are equipped with the knowledge to conduct gas tests for oxygen levels, flammable and toxic gases safely. This training programme also equips the participants with knowledge to conduct gas testing within confined spaces and awareness of associated confined space hazards.

On successful completion of the training, the participants will be able to demonstrate an understanding of:

1. Confined space criteria
2. The hazards of operations within an oxygen deficient, toxic or flammable environment
3. Carrying out a suitable and sufficient risk assessment
4. Using safe systems of work
5. The implications of organisational and statutory requirements
6. Interpreting operational requirements
7. Selecting and using PPE and RPE
8. Working within the Permit to Work system
9. The operating principles of atmosphere monitoring and measuring equipment
10. Gas detector pre-start checks
11. Calibrating the instruments used in atmospheric testing
12. How to set up the relevant detector for each gas testing application
13. The behaviour of different flammable and toxic gases
14. The range and frequency of tests
15. Acceptable levels of flammable and toxic gases
16. Performing gas tests in sequence
17. Obtaining a representative atmosphere sample
18. Monitoring and retesting
19. Where to site ongoing monitoring equipment
20. Interpreting and documenting the results
