What an assessment for PUAFIR202 must cover

79 assessable components: 4 elements (26 performance criteria), 26 performance evidence and 27 knowledge evidence requirements. An audit-defensible tool maps every question and task back to these — that mapping is the coverage matrix Auditori generates alongside the assessment.

Elements & performance criteria

1 Prepare Class A foam for use

1.1Type of foam for application in a wildfire or on non-structural object is selected depending on the required effect of foam on components of the fire triangle and fuel
1.2Decision to apply Class A foam to Class A fuels at wildfire or non-structural incident is received from Incident Controller
1.3Foam proportioning or induction rate is selected, in accordance with manufacturers’ recommendations, organisational procedures and guidelines, to produce the solution strength required to achieve operational objectives with the decision communicated to the crew preparing the foam
1.4Foam expansion or aspiration ratio is confirmed, based on fuel type, operational requirements and need to achieve maximum operational benefit
1.5Class A foam concentrate and equipment is prepared for use, in accordance with organisational procedures and safe work practices with consideration of potential environmental impact and required precautions to be complied with
1.6Correct personal protective clothing and equipment required for working with Class A foam is donned for handling concentrate and solution

2 Operate Class A foam system and equipment

2.1Type of Class A foam system is confirmed through chain of command
2.2Predetermined amount of foam concentrate is added to water flow using appropriate equipment, as directed
2.3Foam system available is operated using predetermined proportioning or induction method
2.4Where system is manually regulated, proportioning percentage rate and flow is monitored and achievement of operational objectives is confirmed

3 Apply Class A foam

3.1Foam system and equipment is operated to produce required solution strength suitable for its intended application as non-aspirated or aspirated foam and for the type of fuel to which it is to be applied
3.2Class A foam is applied as a direct attack to extinguish the edge of the fire using non-aspirated or low expansion foam nozzles
3.3Class A foam is used to wet fuels to construct a control line adjacent to the fire edge, using required foam proportion rate to contribute to fuel reduction burning, burning out and back burning
3.4Foam is applied to conduct mop up/blacking out operations by regulating flow to suit application type and rate
3.5Class A foam is applied to non-structural objects, in accordance with organisational operating procedures for these types of fires
3.6Direct and indirect application of Class A foam is demonstrated, in accordance with organisational operating procedures
3.7Environmental contamination from application of Class A foam is considered and preventative measures are implemented

4 Store and handle Class A foam and prevent damage to equipment and the environment

4.1Class A foam is stored on tankers and appliances in designated storage drums, racks or tanks, in accordance with Work, Health and Safety (WHS)/Occupational Health and Safety (OHS) requirements
4.2Storage arrangements in workplace and other locations for Class A drum stocks of foam concentrate are implemented and adhered to, in accordance with Work, Health and Safety (WHS)/Occupational Health and Safety (OHS) requirements
4.3Measures to control foam leaks or spills are followed, in accordance with organisational procedures
4.4Class A foam tanks are refilled using personal protective clothing and equipment and approved foam concentrate transfer equipment, in accordance with organisational procedures and environmental requirements
4.5Cleaning and safe disposal of any foam spills is undertaken, in accordance with relevant Safety Data Sheets (SDS)
4.6Foam compatibility is considered when using Class A foam solutions from different vehicles on the same fire particularly when mixing one manufacturer’s brand of Class A foam with another’s
4.7Environmental regulations, as specified in organisational procedures, are adhered to when using foam and cleaning spills or foam equipment
4.8Procedures for foam storage, mixing and filling sites are implemented, in accordance with organisational procedures and industry guidelines
4.9Practices that do not contaminate water bodies, storm water drains or agricultural areas are implemented and adhered to when cleaning equipment at an incident or other location where Class A foam is used

Questions about assessing PUAFIR202

What does an assessment tool for PUAFIR202 need to cover?

To satisfy the Principles of Assessment and Rules of Evidence, an assessment for PUAFIR202 needs to address all 79 unit components: 4 elements with 26 performance criteria, 26 performance evidence requirements, 27 knowledge evidence requirements, and the foundation skills. A coverage matrix mapping each question and task to these components is what an auditor looks for.

How does Auditori generate an assessment tool for PUAFIR202?

Auditori pulls the current release of PUAFIR202 from training.gov.au and generates a complete package: candidate assessment, assessor guide with model answers and observation criteria, and a coverage matrix mapping every component. A suitably qualified person then reviews and approves the draft in a built-in workflow — consistent with ASQA's guidance on AI use in VET — before export as branded PDF and editable Word.

Is the first assessment tool really free?

Yes. Every new account includes one free credit — enough to generate the complete assessment tool for PUAFIR202 — with no card and no subscription required. After that it's pay-as-you-go per unit.

Can I check my existing PUAFIR202 assessment instead of generating a new one?

Yes — upload your existing assessment or learner guide and Auditori maps it against every element, performance criterion, PE and KE of PUAFIR202, showing exactly what's covered and what's missing. Mapping costs a quarter of a credit.
