Apply Class A foam

1. 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
2. Class A foam is applied as a direct attack to extinguish the edge of the fire using non-aspirated or low expansion foam nozzles
3. 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
4. Foam is applied to conduct mop up/blacking out operations by regulating flow to suit application type and rate
5. Class A foam is applied to non-structural objects, in accordance with organisational operating procedures for these types of fires
6. Direct and indirect application of Class A foam is demonstrated, in accordance with organisational operating procedures
7. Environmental contamination from application of Class A foam is considered and preventative measures are implemented
