The Echo3 online AGT course is designed to meet the initial training and validation requirements for individuals preparing to work as Authorised Gas Testers (AGT).  The course provides comprehensive training on the use of various gas testing instruments and prepares participants to operate safely in a range of work environments.

An Authorised Gas Tester (AGT) is responsible for conducting tests to measure oxygen levels, and detect flammable and toxic gases, particularly when work is being carried out in confined spaces. AGTs also play a critical role in testing for flammable gases before hot work begins and support safety watch duties during ongoing hot work operations.

Industries that handle hydrocarbons, chemicals, solvents, paints, cleaning products, or generate significant hydrocarbon-based waste may require the use of authorised gas testers.

The knowledge gained in this AGT course will help you understand when, where, and how to carry out essential gas testing to ensure that the atmosphere is safe before starting hot work or working in confined spaces.
