Elements and Performance Criteria

1. Apply Class A foam
   • Foam 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
   • Class A foam is applied as a direct attack to extinguish the edge of the fire using non-aspirated or low expansion foam nozzles
   • Class 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
   • Foam is applied to conduct mop up/blacking out operations by regulating flow to suit application type and rate
   • Class A foam is applied to non-structural objects, in accordance with organisational operating procedures for these types of fires
   • Direct and indirect application of Class A foam is demonstrated, in accordance with organisational operating procedures
   • Environmental contamination from application of Class A foam is considered and preventative measures are implemented
2. Prepare Class A foam for use
   • Type 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
3. Decision to apply Class A foam to Class A fuels at wildfire or non-structural incident is received from Incident Controller
4. Foam 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
5. Foam expansion or aspiration ratio is confirmed, based on fuel type, operational requirements and need to achieve maximum operational benefit
6. Class 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
7. Correct personal protective clothing and equipment required for working with Class A foam is donned for handling concentrate and solution
8. Operate Class A foam system and equipment
   • Type of Class A foam system is confirmed through chain of command
9. Predetermined amount of foam concentrate is added to water flow using appropriate equipment, as directed
10. Foam system available is operated using predetermined proportioning or induction method
11. Where system is manually regulated, proportioning percentage rate and flow is monitored and achievement of operational objectives is confirmed
    • Foam 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
12. Class A foam is applied as a direct attack to extinguish the edge of the fire using non-aspirated or low expansion foam nozzles
13. Class 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
14. Foam is applied to conduct mop up/blacking out operations by regulating flow to suit application type and rate
15. Class A foam is applied to non-structural objects, in accordance with organisational operating procedures for these types of fires
16. Direct and indirect application of Class A foam is demonstrated, in accordance with organisational operating procedures
17. Environmental contamination from application of Class A foam is considered and preventative measures are implemented
18. Store and handle Class A foam and prevent damage to equipment and the environment
    • Class 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
19. Storage 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
20. Measures to control foam leaks or spills are followed, in accordance with organisational procedures
21. Class 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
22. Cleaning and safe disposal of any foam spills is undertaken, in accordance with relevant Safety Data Sheets (SDS)
23. Foam 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
24. Environmental regulations, as specified in organisational procedures, are adhered to when using foam and cleaning spills or foam equipment
25. Procedures for foam storage, mixing and filling sites are implemented, in accordance with organisational procedures and industry guidelines
26. Practices 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

Range Statement

Range is restricted to essential operating conditions and any other variables essential to the work environment. Non-essential conditions may be found in the Companion Volume Implementation Guide.
non-structural objects must include two or more of the following	coal fires hydrocarbon fuels machinery fire dozers and graders motor vehicles small and shallow hydrocarbon fuel spills tyre dumps
measures to control leaks or spills must include	exercising care to avoid spills at mixing and loading areas
