Required Skills
Required skills |
customer service skills language, literacy and numeracy skills to: communicate with others clearly and concisely, verbally and in writing interpret standards, installation plans, drawings and specifications read and record measurements record and report information neatly and legibly understand and comply with work instructions and specifications interpersonal skills to relate to people from a range of social, cultural and ethnic backgrounds planning and organising skills to: estimate time to complete activities prioritise tasks technical skills to: check installation drawing measurements and calculations against actual site values use measurement tools accurately work effectively and safely with others |
Required knowledge |
location and application of relevant information, standards and specifications, such as: AS 4214 Gaseous fire extinguishing systems ISO 14520 Gaseous fire-extinguishing systems – Physical properties and system design methods used to convert units of measurement occupational health and safety (OHS) regulations organisational policies and procedures, including quality requirements ozone depleting substance (ODS) and synthetic greenhouse gas (SGG) regulations, where required relevant federal, state or territory legislation that affects organisational operations, including: anti-discrimination and diversity equal employment opportunity site safety plan state and territory legislation applicable to workplace operations |
Evidence Required
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 | This unit of competency could be assessed by verbal questioning relating to the interpretation of installation drawings and work specifications for two different gaseous fire-suppression system installation projects. |
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 the required skills and knowledge specified in this unit. In particular the person should demonstrate the ability to: locate, interpret and apply relevant information, standards and specifications comply with site safety plan, OHS regulations and ODS and SGG regulations (where required) and state and territory legislation applicable to workplace operations comply with organisational policies and procedures, including quality requirements communicate and work effectively and safely with others read and interpret installation drawings in two different projects, including: confirming amendment status and currency of drawings confirming orientation of drawings to the ground identifying six key features on a drawing and the actual features at the work site confirming six items of information from the title block of the installation drawings identifying six construction dimensions, levels and locations from the installation drawings identifying six ancillary works dimensions, levels and locations from the installation drawings read and interpret two formal specifications, including: identifying dimensions material requirements and processes to be followed. |
Context of and specific resources for assessment | Assessment of essential underpinning knowledge may be conducted in an off-site context. It is to comply with relevant regulatory or Australian standards’ requirements. Resource implications for assessment include: actual or simulated work environment assessment documentation, including training and assessment record books necessary tools and specialist equipment range of design documentation, installation drawings, and other related drawings and specifications relevant manuals and other documentation, including Australian standards. |
Method of assessment | Assessment methods must: satisfy the endorsed Assessment Guidelines of the Property Services Training Package include direct observation of tasks in real or simulated work conditions, with questioning to confirm the ability to consistently identify and correctly interpret the essential underpinning knowledge required for practical application reinforce the integration of employability skills with workplace tasks and job roles confirm that competency is verified and able to be transferred to other circumstances and environments. |
Guidance information for assessment | Reasonable adjustments for people with disabilities must be made to assessment processes where required. This could include access to modified equipment and other physical resources, and the provision of appropriate assessment support. Assessment processes and techniques should as far as is practical take into account the language, literacy and numeracy capacity of the candidate in relation to the competency being assessed. This unit could be assessed on its own or in combination with other units relevant to the job function. |
