Unit of Competency MEA504 - Maintain and fit oxygen masks
Description
Employability Skills
Learning Outcomes and Application This unit of competency 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 and may be performed individually or as part of a team. Fitment involves adjusting the oxygen mask to correctly fit an individual (oxygen masks are not an off-the-shelf issue).This unit is part of the Aeroskills Life Support and Furnishing Certificate III and IV training pathways. The unit is used in workplaces that operate under the airworthiness regulatory systems of the Australian Defence Force (ADF) and the Civil Aviation Safety Authority (CASA).
Duration and Setting X weeks, nominally xx hours, delivered in a classroom/online/blended learning setting.

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.

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 and performance criteria 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 (3) individuals.

This shall be established via the records in the Log of Industrial Experience and Achievement or, where appropriate, an equivalent Industry Evidence Guide.

Assessors must satisfy the requirements of the National Vocational Education and Training Regulator (Australian Skills Quality Authority, or its successors).

2.6

Relevant documentation is completed and processed in accordance with standard enterprise procedures

Evidence required to demonstrate competency in this unit must be relevant to and satisfy all of the requirements of the elements and performance criteria under the specified conditions of assessment, and must include:

applying WHS practices relating to oxygen mask maintenance processes

using MSDS

using applicable tools, testing/measuring equipment and maintenance documentation to:

solder oxygen mask electronic/electrical components

test the operation of helmet electronic/electrical components

replace unserviceable components in accordance with approved procedures

select and use appropriate oxygen mask cleaning materials

correctly fit oxygen masks to users

safely using the oxygen test rig

cleaning and maintenance of equipment and tools

correctly disposing of hazardous waste.

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.

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.

Evidence required to demonstrate competency in this unit must be relevant to and satisfy all of the requirements of the elements and performance criteria and include knowledge of:
