Unit Descriptor
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. |
Application of the Unit
This unit requires application of skills and knowledge relating to the maintenance and fitment of oxygen masks worn by aircrew. Maintenance involves inspection, testing, fault diagnosis, replacement of parts, cleaning and functional testing. Fitment involves adjusting the oxygen mask to correctly fit an individual. |

Elements and Performance Criteria Pre-Content
Elements describe the essential outcomes of a unit of competency. |
Performance criteria describe the performance needed to demonstrate achievement of the element. Where bold italicised text is used, further information is detailed in the required skills and knowledge section and the range statement. Assessment of performance is to be consistent with the evidence guide. |
Elements and Performance Criteria
1. Maintain oxygen mask |
1.1. Oxygen mask is inspected for serviceability in accordance with standard procedures 1.2. Oxygen mask is tested for serviceability in accordance with standard procedures and manufacturer's specifications 1.3. Identified faults beyond own authority to rectify are reported to supervisor and faulty oxygen mask is quarantined 1.4. Unserviceable parts of the oxygen mask are replaced in accordance with standards procedures 1.5. Communication system components are tested in accordance with standard procedures 1.6. Oxygen mask is cleaned in accordance with standard procedures 1.7. Oxygen mask is presented for inspection by supervisor in accordance with standard procedures 1.8. Maintenance documentation is completed and processed in accordance with standard enterprise procedures |
2. Fit oxygen mask |
2.1. Fitting process is explained to the participant so that optimal fit can be achieved through relevant feedback 2.2. Participant is measured to select an appropriate size oxygen mask 2.3. Components of oxygen mask are adjusted to optimise fit 2.4. Integration of the oxygen mask and helmet is confirmed for correct function during operations 2.5. Oxygen mask fit is verified through participant feedback and by the supervisor 2.6. Relevant documentation is completed and processed in accordance with standard enterprise procedures |

Overview of assessment |
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. |
Critical aspects for assessment and evidence required to demonstrate competency in this unit |
The underlying skills inherent in this unit should be transferable across a range of aircraft life support equipment maintenance activities. It is essential that oxygen mask testing and inspection procedures, cleanliness requirements and safety precautions are fully observed, understood and complied with. Ability to interpret maintenance and fitting procedures and apply them in practice is critical. Evidence of transferability of skills and knowledge related to oxygen mask maintenance and fitting is essential. This is to be demonstrated through demonstration of the ability to recognise faults and damage and perform appropriate repairs that are within the bounds of the individual's authority, and through the demonstration of correct fitting procedures. The work plan should take account of applicable safety and quality requirements in accordance with the industry and regulatory standards. A person cannot be assessed as competent until it can be demonstrated to the satisfaction of the workplace assessor that the relevant elements of the unit of competency are being achieved under routine supervision on at least three (3) unserviceable oxygen masks providing a representative range of maintenance tasks and on the correct fitting of oxygen masks to at least three individuals. This shall be established via the records in the Log of Industrial Experience and Achievement or, where appropriate, an equivalent Industry Evidence Guide. |
Context of and specific resources for assessment |
Competency should be assessed in the workplace or simulated workplace using materials, tools and equipment specified in the maintenance manuals and applicable procedures. It is also expected that general and special purpose tools and ground support equipment would be used where appropriate. |
