Tips for gathering evidence to demonstrate your skills

The important thing to remember when gathering evidence is that the more evidence the better - that is, the more evidence you gather to demonstrate your skills, the more confident an assessor can be that you have learned the skills not just at one point in time, but are continuing to apply and develop those skills (as opposed to just learning for the test!). Furthermore, one piece of evidence that you collect will not usualy demonstrate all the required criteria for a unit of competency, whereas multiple overlapping pieces of evidence will usually do the trick!

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 appropriate WHS practices and using approved maintenance documentation and aircraft publications relating to aircraft oxygen systems and components

demonstrating the procedure to replenish a dry breathing oxygen system, including:

correct identification of oxygen ground trolleys

maximum charging pressures for low and high pressure systems

safety precautions to be adhered to during replenishment

correct order of procedural replenishment steps

demonstrating the procedure to purge a dry breathing oxygen system, including:

reasons for the requirement to undertake a purging operation

identification of acceptable system purging gases

safety precautions to be adhered to during purging

employing correct techniques when purging oxygen storage cylinders or systems.
