Course Description

This unit of competency is part of the Aeroskills Life Support and Furnishing Certificate III and IV training pathways. It covers the competencies required to maintain and fit oxygen masks worn by aviation aircrew. Maintenance involves inspecting, testing, isolating faults, replacing parts, cleaning and testing prior to placing the item back in service. Fitting an oxygen mask includes adjusting the mask to fit the individual (oxygen masks are not an off-the-shelf issue). This unit is used in workplaces that operate under the airworthiness regulatory systems of the ADF and CASA.
This unit is equivalent to PUADEFLS004B Maintain and fit oxygen masks.
A person who demonstrates competency in this unit must be able to maintain and fit oxygen masks while observing all relevant safety precautions, especially those relating to oxygen.
