WILDFIRE Flashcards
What is the SOG that applies to ACTFR wildfires?
SOG 7
How would you get to know the area around your station?
Area Familiarisation
How would you be alerted to a wildfire as a crew at station on on an appliance?
DITO, MDT, ComCen, Member of the public contacting the station
What information would you need to obtain from someone alerting the station to a fire (or incident)?
Name, contact details, location and any information about the incident.
What level PPE should you wear for wildfires?
Level E
What are the three methods of heat transfer?
Radiation
Convection
Conduction
What are the three types of bushfire?
Ground
Surface
Crown
What is a ground fire?
Burns the organic material in the soil layer
What is a surface fire?
Burns/Travels above the ground surface in vegetation such as grass, low shrubs and forest litter
What is a crown fire?
Burns in the crowns/canopies of trees ahead and above of an intense fire in the undergrowth
What is spotting?
A new fire which has been ignited ahead of the main fire by embers or a fire brand.
Two examples of surface fires:
- Grassland- light to moderate fuels, maximum wind penetration, high ROS, short residual burning time
- Forest Fire- Heavy fuel loads, restricted wind penetration, bark fuels,
3 factors that effect fire behaviour
Fuel
Weather
Topography
Explain Fuel:
Types- grass, litter, shrubs, trees
Size/Quantity- Fine fuels are smaller (grass, leaves, tiwgs)
heavy fuels are bigger, thicker, denser (logs etc)
Arrangement- fine loosely packed burns quickly and fiercly
Moisture content- determined by how damp the fuel is
Explain fuel arrangement further:
Canopy, bark fuel, elevated fuel, near-surface fuel, surface fuel
