Instructions
- Read each section carefully. This worksheet will help you understand the science and safety behind fuel reduction burning.
- Complete the activities in order. The tasks start with basic concepts and move into more complex planning.
- Use the data provided. When calculating or filling in tables, use the measurements and facts listed in the prompts.
- Think like a Fire Warden. Always prioritize safety and environmental responsibility in your answers.
Section 1: The Fire Triangle
To manage fire, we must understand what makes it burn. Fire requires three elements to exist. If you remove one, the fire goes out.
1. Label the three elements of the Fire Triangle below:
- A: ____ (The wood, leaves, and branches being burned)
- B: ____ (The spark or flame that starts the reaction)
- C: ____ (The gas in the air that feeds the flame)
2. Which element are you managing when you collect dry leaves and branches for a controlled burn? Circle one:
- Fuel Load
- Oxygen Levels
- Chemical Reaction
Section 2: Managing the Fuel Load
Reducing the amount of "fuel" on a property lowers the intensity of a bushfire. On a one-acre property, different materials contribute differently to the fuel load.
Complete the table below to categorize the materials collected from the property.
| Material Type | State (Dry/Green) | Why it is a fire risk? | Disposal Method |
|---|---|---|---|
| Example: Eucalyptus Leaves | Dry/Brown | High surface area; ignites very fast. | Controlled Burn Pile |
| Large Fallen Branches | |||
| Pine Needles | |||
| Tall Dry Grass | |||
| Old Wooden Fence Posts | |||
| Small Twigs/Kindling |
Section 3: The DFES Safety Checklist
The Department of Fire and Emergency Services (DFES) provides guidelines to ensure burns don't escape. Look at the conditions below and determine if it is Safe or Unsafe to burn.
- Wind speed is 25km/h with strong gusts. [ __ ]
- There is a 3-meter cleared
