Chainsaw Safety: Safe Operation & Kickback Prevention

Inspect the Saw. Control the Area. Protect the Crew.

Chainsaws are commonly used for cutting brush, removing branches, and clearing vegetation. Improper operation can cause serious injuries, including severe cuts, amputations, and fatalities. Common hazards include kickback, flying debris, falling branches, unstable footing, and contact with the moving chain. Only employees who have received appropriate training and authorization may operate chainsaws. This toolbox talk provides general safety awareness and does not replace hands-on training, manufacturer instructions, or site-specific safety procedures.

Required Personal Protective Equipment (PPE)

Before operating a chainsaw, wear appropriate PPE based on the equipment and hazards:

• Hard hat when exposed to falling branches or overhead hazards.
• Safety glasses with side protection and a face shield when needed.
• Hearing protection.
• Chainsaw-resistant chaps or protective pants.
• Sturdy, slip-resistant safety boots with appropriate cut protection.
• Work gloves that provide a secure grip and suitable protection.
• High-visibility clothing when working near vehicles or equipment.

Do not wear loose clothing, jewelry, or anything that could become caught in the chainsaw. Inspect PPE before use. Replace damaged or defective equipment.

Inspect the Chainsaw Before Use

Before starting the chainsaw:

• Check the chain for damage, sharpness, and proper tension.
• Make sure the chain brake operates properly.
• Inspect the throttle trigger and safety lockout.
• Check handles, guards, and other safety devices.
• Inspect for loose or missing parts.
• Check for fuel and oil leaks.
• Verify that the chain is properly lubricated.
• Follow the manufacturer’s inspection instructions.

Never operate a damaged or defective chainsaw. Remove it from service and notify your supervisor.

Prevent Chainsaw Kickback

Kickback occurs when the upper tip of the chainsaw guide bar contacts an object or the chain becomes pinched, causing the saw to move suddenly toward the operator. To reduce the risk of kickback:

• Always maintain a firm, two-handed grip.
• Keep your thumbs wrapped around the handles.
• Avoid cutting with the upper tip of the guide bar.
• Keep the chain properly sharpened and tensioned.
• Use manufacturer-approved safety devices and cutting equipment.
• Never cut above shoulder height.
• Maintain stable footing and proper balance.
• Never operate the chainsaw with one hand.

Kickback can happen without warning and may cause serious or fatal injuries.

Safe Chainsaw Operating Practices

When operating a chainsaw:

1. Inspect the work area for hidden hazards, debris, and unstable ground.
2. Check for overhead branches, dead limbs, and nearby power lines.
3. Start the chainsaw on the ground or another firm support with the chain brake engaged.
4. Never drop-start a chainsaw.
5. Maintain a firm grip with both hands.
6. Keep your body away from the cutting chain.
7. Never reach across or underneath a moving chain.
8. Keep coworkers and bystanders outside the cutting hazard area.
9. Watch for branches or logs that may shift, roll, or spring back when cut.
10. Never cut above shoulder height or operate from a ladder.
11. Stop cutting immediately if you lose your footing or control.
12. Shut off the engine before adjusting the chain or performing maintenance.
13. Never leave a running chainsaw unattended.

Never attempt tree felling, cutting unstable trees, or working with heavily tensioned limbs without appropriate training and an approved work plan.

Brush Cutting & Vegetation Clearing Safety

Before clearing brush or vegetation:

• Identify rocks, wire, metal, debris, and other hidden hazards.
• Watch for uneven ground, holes, and slippery surfaces.
• Inspect trees and branches for signs of instability.
• Identify nearby power lines and electrical equipment.
• Establish a safe cutting area and keep other workers clear.
• Maintain communication with nearby coworkers.
• Stop work if weather, visibility, or ground conditions become unsafe.

Vegetation near electrical lines must not be cut until the electrical hazards have been evaluated and appropriate protective measures established by qualified personnel.

Fueling & Transporting Chainsaws

• Turn off the engine and allow it to cool before refueling.
• Use approved fuel containers.
• Refuel at least 10 feet from ignition sources.
• Never smoke while handling or dispensing fuel.
• Start the chainsaw at least 10 feet from the fueling area.
• Clean up fuel spills before restarting.
• Engage the chain brake or shut off the engine when moving across hazardous terrain.
• Shut off the engine and use the guide-bar cover during vehicle transport or storage.

Emergency Preparedness

Chainsaw injuries can result in severe bleeding and require immediate medical attention.

• Know the jobsite emergency procedures.
• Confirm emergency communication is available.
• Know the location of first-aid supplies.
• Keep access routes clear for emergency responders.
• Report all injuries and near misses immediately.
• Call 911 for serious injuries or life-threatening emergencies.

Do not attempt a rescue or enter an unsafe cutting area until the hazard has been controlled.

OSHA Safety Resources

For additional chainsaw safety information, review the following OSHA publications:

• OSHA Chainsaw Safety QuickCard
• OSHA Working Safely with Chainsaws Fact Sheet

Relevant OSHA construction standards include 29 CFR 1926.300 (Hand and Power Tools) and applicable PPE, electrical safety, and fire prevention requirements.

Report Unsafe Conditions

Stop work and notify your supervisor immediately if:

• The chainsaw is damaged or malfunctioning.
• The chain brake or other safety devices are defective.
• Required PPE is missing or damaged.
• Branches, trees, or cutting materials appear unstable.
• Electrical hazards are present.
• Coworkers or bystanders enter the cutting area.
• Conditions prevent safe operation.
• An injury, near miss, or equipment incident occurs.

For serious injuries or emergencies, call 911. For additional safety information, contact: Allison Ash, RSO Email: acash@cityconstructionco.com Cell: (484) 802-8605

Remember

• Only trained and authorized employees may operate chainsaws.
• Wear appropriate PPE, including chainsaw leg protection.
• Inspect the chainsaw before use.
• Keep both hands firmly on the handles.
• Never cut above shoulder height.
• Watch for kickback and falling branches.
• Maintain safe footing and a clear cutting area.
• Keep coworkers and bystanders away from cutting operations.
• Remove unsafe equipment from service.
• Stop work when conditions cannot be controlled safely.

Chainsaw safety depends on proper training, equipment inspection, awareness, and safe operating practices. Saving a few seconds is never worth a serious injury.
