Study Notes
Safety Precautions
- Using a high-revving chainsaw requires caution to prevent serious injuries from kickback.
- Kickback can cause the inertia chain brake to engage or drive the chain brake handle back, stopping the chain's movement.
- Proper handling and operation of the saw are essential to minimize risks.
- Always keep body parts away from the cutting path when using a chainsaw.
- Operating the saw below chest height improves visibility and control.
- Ensure the chain only contacts the intended cutting material.
- A running chainsaw must be set down with the chain brake engaged to prevent accidents.
- Engage the chain brake while moving (not operating) a running chainsaw.
- Avoid running chainsaws at full throttle with no load for longer than 5-10 seconds.
Minimum Protective Equipment
- Required protective gear includes gloves, hearing protection, eye protection, helmet, and steel-toed boots.
- Chaps must be worn during all training activities and non-emergency responses for operator protection.
Fuel
- Power tools utilize two engine types: 2-cycle engines and 4-cycle engines.
- Chainsaws and cut-off saws operate with 2-cycle engines, needing a pre-mixed fuel/oil blend for proper lubrication.
- Always use a container labeled "MIXED FUEL" in yellow for 2-cycle fuel to avoid misuse.
- Other power tools, like generators and powered fans, use 4-cycle engines with high-octane unleaded fuel.
- Bar oil and a 50:1 fuel mix are to be stored at the station, not on fire apparatus.
