EVIDENCE GUIDE
The evidence guide provides advice on assessment and must be read in conjunction with the performance criteria, required skills and knowledge, the range statement and the Assessment Guidelines for this Training Package.
Overview of assessment
Competency in this unit underpins competency in other aspects of the candidate's role in managing their work tasks.
This unit could be assessed on its own or in combination with other units of competency relevant to the job function.
Critical aspects for assessment and evidence required to demonstrate competency in this unit
A person who demonstrates competency in this unit must be able to provide evidence of:
locating, interpreting and applying relevant information, standards and specifications
creating designs for gaseous fire suppression systems based on two different gaseous extinguishing agents
complying with site safety plan, OHS regulations, ODS and SGG regulations (where required) and state and territory legislation applicable to workplace operations
complying with organisational policies and procedures, including quality requirements
communicating and working effectively and safely with others
in a minimum of two different settings:
identifying legal and industry requirements that apply to system design
analysing system design requirements
identifying and confirming system and site measurements, critical dimensions and system data
identifying risk requirements
identifying constraints to system design
developing strategies to address identified constraints

identifying and selecting appropriate products, extinguishing agents, hardware and components for use in system design
incorporating variations and modifications into system design
completing system design calculations
drafting system design drawings
preparing bill of materials for system design
identifying installation and commissioning procedures for system design
identifying safety procedures to be followed during installation and commissioning procedures
creating installation and commissioning documentation for system and components, pipes, fittings, actuation control devices, activating mechanisms and auxiliary shutdown interface, as required.
Specific resources for assessment
Resource implications for assessment include access to:
actual or simulated work environment, including gaseous fire suppression system software
customer specifications, tender or quotation documentation, and installation and maintenance requirements for a gaseous fire suppression system design
assessment documentation, including training and assessment record books
all necessary tools, specialist equipment, materials and spare parts
relevant manuals and other documentation, including Australian standards.
Where applicable, physical resources should include equipment modified for people with disabilities.
Access must be provided to appropriate learning and/or assessment support when required.
Assessment processes and techniques must be culturally appropriate, and appropriate to the oracy, language and literacy capacity of the candidate and the work being performed.
Context of assessment
For valid and reliable assessment of this unit, competency should be demonstrated over a period of time and be observed by the assessor (or assessment team working together to conduct the assessment).
Competency is to be demonstrated in a range of situations, reflecting the practical requirements of the workplace which may include customer and workplace interruptions and involvement in related activities normally experienced in the workplace.
Assessment of competency over the full range of performance criteria may be made through practical demonstrations in the work place. Consideration should be given to assessing consistency of outcome over an appropriate period of time.
Candidates should also be given the opportunity to practise and undertake self-assessment of performance before requesting formal assessment.
All safety requirements must be adhered to during all practical activities.
Oral questioning or a written assessment may be used to assess underpinning knowledge. (In assessment situations, where the candidate is offered a preference between oral questioning and written assessment, questions are to be identical.)
Assessment of evidence should establish the candidate's ability to perform the job to the standard required in the workplace.
Supplementary evidence may be obtained from relevant authenticated correspondence or reports from supervisors or team leaders that demonstrate an understanding of the requirements for gaseous fire suppression system design.
Candidate should be encouraged to compile a portfolio of examples of completed documentation relevant to the candidate's organisation. One accurate example of each completed document is suggested as sufficient to infer competency and ability to transfer appropriate skills to each document type when required in the workplace. (Oral questioning may contribute as evidence of this ability.)
Information derived from enterprise policies and practices must be treated as commercial-in-confidence.
In all cases where practical assessment is used it will be combined with targeted questioning to assess the underpinning knowledge.

Questioning will be undertaken in such a manner as is appropriate to the oracy, language and literacy levels of the candidate and any cultural issues that may affect responses to the questions. It will reflect requirements of the unit of competency and the work being performed.
Where assessment is for the purpose of recognition (RCC or RPL), the evidence provided will need to be authenticated and show that it represents current competency demonstrated over a period of time.
Performance and assessment of this unit must be carried out within the relevant requirements of the following legislative and industry framework:
building Acts, regulations and codes
Australian and international standards identified as relevant to gaseous fire suppression design
environmental regulations
manufacturer specifications
organisational requirements, including policies and procedures relating to ODS, SGG and OHS
OHS legislation, codes and regulations
ODS and SGG legislation, codes and regulations.
