Course Overview
The Gas Test Atmospheres (GTA) course gives learners the practical skills to test the working atmosphere using electronic gas detection equipment. It covers how to identify hazardous atmospheres, operate detection equipment, interpret readings, and take appropriate action to confirm an area is safe before work begins.
The 1-day Gas Test Atmospheres course delivered at ERGT Australia provides learners with the practical knowledge and hands-on experience required to test the working atmosphere prior to entering or undertaking work in a specific area or workspace. Designed for both new and experienced workers, this course focuses on identifying hazardous atmospheres, preparing and operating electronic gas detection equipment, interpreting readings, and taking appropriate action in accordance with workplace procedures and legislative requirements.
Through a combination of facilitator-led learning and practical activities in a simulated work environment, learners will build the confidence and capability to prepare for and conduct atmospheric testing, interpret and record results and maintain gas detection equipment in line with manufacturer instructions and industry best practice. Upon successful completion, learners will be job-ready to conduct gas testing activities in support of permit-controlled work, confined space entry, hot work and other high-risk tasks requiring atmospheric verification.

Prior Skills & Knowledge
What to expect
Learner Support:
- Learner wellbeing for this course is supported through measures that recognise the physical, cognitive, and psychological demands of gas testing within simulated high-risk environments. As the course involves the use of gas detection equipment, exposure to simulated hazardous atmospheres, interpretation of atmospheric readings, and application of safety-critical procedures, ERGT implements support strategies that prioritise learner safety, confidence and readiness. This ensures learners can safely participate in all practical components without compromising their wellbeing or safety.
Physical Wellbeing Support:
- Trainers monitor learners for signs of fatigue, discomfort or unsafe manual handling practices while using gas detection equipment.
- Learners are encouraged to disclose any physical concerns (e.g. fatigue, minor injury or restricted movement) so adjustments can be made to participation.
Psychological & Emotional Wellbeing Support:
- Trainers provide clear pre-activity briefings outlining gas hazards, alarm conditions, exposure limits and required responses.
- Learners experiencing discomfort or uncertainty when interpreting readings or responding to simulated hazardous conditions are supported through additional guidance and structured practice.
- Post-activity debriefs are conducted to reinforce correct decision-making, address concerns and build confidence in gas testing processes.
Cognitive Support for Safety-Critical Tasks:
- Step-by-step demonstrations of gas detection equipment use, including bump testing, calibration verification and sampling techniques.
- Use of visual aids, live demonstrations and real equipment to reinforce understanding of gas detection principles and safe operating procedures.
- Opportunities to practise interpreting readings and responding to simulated conditions in controlled environments before formal assessment.
