Gas Tester

Gas Tester


Training shall consist of a combination of formal instruction (e.g., lecture, discussion, interactive, video, written material), practical training (demonstrations performed by the trainer and practical exercises performed by trainee) and evaluation of the candidates performance at the work site. Each candidate will undergo a theory assessment test and a Practical Gas Testing Assessment for successfully completion of the course.

Completed checklists in addition to completed multiple-choice questions would be assessed to verify competence.

Course Objective

By the end of this course participants should be able to:

  • Understand the risks associated with confined space entry
  • Understanding operational instructions
  • Know Codes of Practice and Guidance Notes
  • Know the testing requirements for oxygen, flammable and toxic gases
  • Recognize problems and limitations in their knowledge and expertise
  • Understanding and recording of results
  • Understand the hazards of deficient, environments
  • Understand the properties of different gases Know the acceptable levels
  • Understand the operating principles of atmosphere monitoring and measuring equipment
  • Know of when and why gas testing is required, i.e. for confined spaces and for hot work.
  • Select, maintain and use the correct gas testing quipment.

Target Audience

The course is aimed at personnel performing or supervising excavation activities
