Chain Saws



IRPG 2025 p86

Chainsaw Operations


Assess the complexity, complete a hazard analysis, and the sawyer must:

establish cutting area control.


Indicators of Complexity

• Evaluate sawyer fatigue

• Evaluate tree stand health

• Evaluate pace of operations

• Evaluate effects of terrain

• Evaluate weather factors

• Evaluate objective difficulty

Chainsaw Operation Standards

• Establish cutting area control/brief all cutting area resources.

• Determine objective–where each cut piece will end up

• Assess hazards

• Overhead/ground hazards

• Species specific hazards

• Determine tree soundness or defects

• Measure lean/bind(s), determine good side/bad side

• Develop an escape plan for the cutting situation

• Establish cut plan/wedge plan

• Establish complexity of the cutting operation

• Complete go/no-go decision

• Communicate and execute cut plan


• Maintain situational awareness while cutting

       Never forget maintaining and updating your LCES

• Give all-clear
