Hazard Tree Felling - Hang-ups
Felling a hung-up hazard tree is a particularly hazardous and complex task. Safely felling a hang-up requires extreme caution and expertise.
The following are some topics sawyers should review during tailgate safety discussions to address felling hang-up hazard trees:
Size up and Evaluation:
- Cut/No Cut (walk-a-way). Is tree secure and does it need to come down?
- What type of hang-up? In a fork, pinched between two trees or resting on limbs?
- Vertical hang-ups have increased complexities.
- Condition of all relevant trees; live, dead, rot, etc.Does the hang-up tree have any weak areas that could fail?
- Obscured view of top?
- If sawyer is unsure of outcome do not attempt to cut leaner.
- Escape routes for unforeseen circumstances?
- Consider falling trees as a group.
- Consider face cuts versus slash cuts for directional control.
- Rope Technique allows increased distance from danger zones
- Heavy equipment/cable
- No Work Zones
Discuss any personal lessons learned with hang-up trees that you may have experienced.
