This document provides information on chain saw safety training. It outlines the objectives of the training, which are to describe the elements of a job hazard analysis, define required personal protective equipment, and apply a situational awareness checklist. It then details the various components of a job hazard analysis, types of personal protective equipment like hardhats and chaps, and considerations for situational awareness regarding overhead hazards, escape routes and cutting area control for tasks like limbing, bucking and felling trees.

Unit 1 Objectives
Upon completion of this lesson, the
student will be able to:
• Describe the elements of a Job Hazard
Analysis required for chain saw
operations
• Define the Personal Protective Equipment
required for chain saw operations.
• Apply the Situational Awareness-
Individual Complexity Checklist.
3. 01-3-S212-EP
Job Hazard Analysis
• Task or procedure to be
accomplished
• Identify the hazards associated with
the task or procedure
• Identify abatement actions to
mitigate hazard
• Identify first aid supplies and
emergency evacuation procedures

How Chain Saw Chaps
Protect the User
When a saw chain
strikes the chaps,
Kevlar fibers are
pulled into the
chain saw’s drive
sprocket, slowing
and quickly
stopping the chain.

Inspection and Replacement
Replace chain saw chaps when:
• The outer shell has numerous holes and cuts.
• Wood chips and saw dust are evident in the
bottom of the chaps.
• Repairs have stitched through the protective
pad.
• Cleaning has been improper.
• High-pressure washing has destroyed the
protective pad.
• The chaps have a cut more than 1 inch long
in the first layer of yellow Kevlar.

Situational Awareness
Checklist of Personal Safety
Considerations and Attitude:
• Am I exercising sound judgment and
awareness?
• Is my attitude influencing me to go against
my better judgment (gut feeling)?
• Do I have all of the required PPE and
sawing equipment to do the job safely?
• Am I in an unfamiliar environment and
timber type?
• Do I watch out for my coworkers and the
public?
13. 01-13-S212-EP
Escape Routes/Safety Zones
• Before cutting, always:
• Identify and mitigate overhead and
ground hazards
• Establish escape routes and safe
zones
• Establish cutting area control
15. 01-15-S212-EP
Limbing
• Overhead and ground hazards
• Escape routes and safety zones
• Cutting area control
• Limbs under tension or spring poles
Prior to Limbing, examine the tree or log
and immediate area for:
21. 01-21-S212-EP
Bucking
• Binds, tension, compression
• Ground slope, roll hazard
• Rocks, root wads
• Overhead hazards, spring poles
• People and property in cutting zone
Examine the log and immediate area for:
25. 01-25-S212-EP
Felling
• Examine the immediate work area
• Examine the surrounding terrain
• Analyze the felling job
• Assess for overhead hazards
• Observe the base of the tree
35. 01-35-S212-EP
People within
2 tree lengths?
Inattention?Engine noise
prevents effective
communication?
Working
directly downhill from
falling operation?
36. 01-36-S212-EP
Neither person
is watching for
overhead hazards?
Employee in
danger zone:
kickback path?
Butt will
most likely fly up
when bole lands
on log?
Poor control
of running
saw?
No wedges?
Possible
dutchman?
