AUTHORIZED GAS TESTER TRAINING

Gas testing is an important part of safe work, particularly when people may enter or work in confined spaces. The Authorized Gas Tester training is designed to give delegates a thorough theoretical understanding of how to conduct gas tests for oxygen levels, flammable gases and toxic gases. The training covers confined-space hazards, atmospheric testing, gas detection equipment, exposure limits, respiratory protection and the actions required when unsafe atmospheric conditions are identified.

The training also explains that confined spaces can include chambers, tanks, vats, silos, pits, trenches, pipes, sewers, flues, wells and other similar spaces where an enclosed nature creates a reasonably foreseeable specified risk. Restricted access and exit, together with the risks of entrapment, entanglement and engulfment, mean that the space must be made as safe as possible before entry.

TRAINING OBJECTIVES

The aims and objectives of Authorized Gas Tester training are to:

  • Give delegates a thorough theoretical understanding of gas testing.
  • Enable delegates to understand and test oxygen levels.
  • Enable delegates to understand and test for flammable gases.
  • Enable delegates to understand and test for toxic gases.
  • Develop awareness of confined-space hazards and the need for safe systems of work.
  • Explain the purpose of risk assessment, permit-to-work systems, isolation, rescue arrangements and standby personnel.
  • Develop knowledge of atmospheric gas testing and monitoring.
  • Explain the correct use, testing, calibration and maintenance of gas detection equipment.
  • Explain the correct sequence for atmospheric testing.
  • Develop awareness of respiratory protective equipment and breathing apparatus requirements.

LEARNING OUTCOMES

By attending the training, delegates should be able to:

  • Define a confined space and identify common examples such as tanks, chambers, pits, trenches, pipes, sewers and wells.
  • Understand the hazards associated with restricted entry and exit, entrapment, entanglement and engulfment.
  • Understand the importance of avoiding confined-space entry where the work can be carried out from outside.
  • Understand the basic confined-space risk assessment process.
  • Understand the meaning of ALARP and the need to reduce risks as low as reasonably practicable.
  • Understand the purpose of a permit-to-work system and the roles involved in it, including the gas tester, permit user, permit authoriser and isolating authority.
  • Understand the importance of rescue plans, standby personnel, communication and toolbox talks.
  • Recognise common gases and their hazards, including oxygen, hydrogen sulphide, methane, propane, butane, benzene and carbon monoxide.
  • Understand oxygen deficiency and oxygen enrichment and their possible effects on workers.
  • Understand the difference between Lower Explosive Limit (LEL), Upper Explosive Limit (UEL) and explosive range.
  • Understand workplace exposure limits and the difference between LTEL and STEL.
  • Understand the hazards and effects of hydrogen sulphide (H2S).
  • Understand how gases behave according to their density compared with air.
  • Understand when and why atmospheric gas testing and continuous monitoring are required.
  • Understand fixed and portable gas detectors and the factors used to select detector locations.
  • Carry out or understand pre-use checks, bump tests and calibration requirements for gas detectors.
  • Understand the required sequence of testing: oxygen, flammable atmosphere and toxic atmosphere.
  • Understand the importance of sampling at the top, middle and bottom of a confined space.
  • Understand the limitations of filtering respirators and when breathing apparatus is required.
  • Understand the importance of recording gas-test results and taking appropriate action when unsafe readings are obtained.

BENEFITS OF TRAINING

Confined spaces can contain oxygen-deficient, oxygen-enriched, flammable or toxic atmospheres that may change without warning. Proper gas testing helps identify these atmospheric hazards before and during work. The training helps delegates understand how to use gas detection equipment, interpret readings and recognise when an atmosphere is unsafe.

On completion of the training, participants will have improved awareness of confined-space hazards, atmospheric testing, gas detector checks, exposure limits, respiratory protection, continuous monitoring and emergency arrangements. This supports safer decision-making before and during confined-space work.

HOW WE DELIVER TRAINING

The training material is delivered through:

  • PowerPoint presentations.
  • Instructor-led explanation and discussion.
  • Questions and answers during the training.
  • Confined-space examples and practical illustrations.
  • Practical demonstration of gas detector pre-use checks.
  • Discussion and demonstration of bump testing and calibration.
  • Appreciation of respiratory protective equipment and key maintenance and pre/post-use inspections.
  • Written and multiple-choice knowledge assessment.

ASSESSMENT

The PowerPoint states that the course includes a 20-question written theory test. The test has a duration of 30 minutes and includes multiple-choice and written questions. The stated goal is 80% and above, and the test is described as open book.
