Unit Descriptor

Unit descriptor 

This unit covers dismantling, inspecting, repairing, replacing, servicing and assembling fire and security containers and their components.

Application of the Unit

Application of the unit 

The unit applies to service and repair work on commercial and domestic fire and security containers. It may apply to regular servicing or call-out work and may be required after entry has been gained.

Appropriate factors that ensure conformance to specifications, operational performance, quality and safety must be applied. These include locksmithing principles, ethics, techniques, procedures and safe workshop practices.

Where interpretation of detailed, complex manufacturer information and specifications is required, Unit MEM16012A (Interpret technical specifications and manuals) should also be considered.

Where gaining entry and re-instatement by straightforward replacement of existing or replacement parts is required, Unit MEM20009A (Gain entry and reinstate fire and security containers) should be selected.

If welding skills are required, then appropriate units should be selected.


This unit has dual status and is to be regarded as both a Specialisation band A unit and Specialisation band B unit for progression to C5 (AQF level V).

Evidence Guide


The evidence guide provides advice on assessment and must be read in conjunction with the performance criteria, required skills and knowledge, range statement and the Assessment Guidelines for the Training Package.

Overview of assessment 

A person who demonstrates competency in this unit must be able to service, repair, test and return to service fire and security containers. Competency in this unit cannot be claimed until all prerequisites have been satisfied.

Critical aspects for assessment and evidence required to demonstrate competency in this unit 

Assessors must be satisfied that the candidate can competently and consistently perform all elements of the unit as specified by the criteria, including required knowledge, and be capable of applying the competency in new and different situations and contexts.

Context of and specific resources for assessment 

This unit may be assessed on the job, off the job or a combination of both on and off the job. Where assessment occurs off the job, that is the candidate is not in productive work, then an appropriate simulation must be used where the range of conditions reflects realistic workplace situations. The competencies covered by this unit would be demonstrated by an individual working alone or as part of a team. The assessment environment should not disadvantage the candidate.

This unit could be assessed in conjunction with any other units addressing the safety, quality, communication, materials handling, recording and reporting associated with servicing and repair of fire and security containers, or other units requiring the exercise of the skills and knowledge covered by this unit.

Method of assessment 

Assessors should gather a range of evidence that is valid, sufficient, current and authentic. Evidence can be gathered through a variety of ways including direct observation, supervisor's reports, project work, samples and questioning. Questioning techniques should not require language, literacy and numeracy skills beyond those required in this unit of competency. The candidate must have access to all tools, equipment, materials and documentation required. The candidate must be permitted to refer to any relevant workplace procedures, product and manufacturing specifications, codes, standards, manuals and reference materials.
