  • 7. 01-7-S212-EP Personal Protective Equipment For this course and for ANY fireline assignment, ALL sawyers and swampers WILL wear the required PPE. 01-7-S212-EP
  • 8. 01-8-S212-EP 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.
  • 9. 01-9-S212-EP Chain Saw Injuries
  • 10. 01-10-S212-EP 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.
  • 11. 01-11-S212-EP 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?
  • 12. 01-12-S212-EP Evaluating the Complexity of the Assignment • Physical considerations • Environmental considerations
  • 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
  • 14. 01-14-S212-EP SAFETY Situational Awareness Exercise Watch Outs for: Limbing Bucking Falling 01-14-S212-EP
  • 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:
  • 16. 01-16-S212-EP Area not cleared? Bar may not be visible? Tip / kickback? Limbing
  • 17. 01-17-S212-EP Power head above shoulders? Escape Route? Tripping hazards; work area not cleared?
