1. Scope

This Safe Work Procedure (SWP) outlines the safety requirements and procedures for the safe operation of chainsaws. It applies to all personnel who operate chainsaws for any purpose. This SWP covers pre-start checks, PPE requirements, safe operating techniques, and emergency procedures.

2. Definitions

Kickback The reactive force or movement of the chainsaw guide bar occurring when the chain is pinched or encounters an obstruction during cutting. Chain Brake A device designed to reduce the risk of kickback injuries by stopping the chain when kickback is detected. Risk Assessment The process of identifying potential hazards and implementing control measures to minimize the risk of injury or damage.

3. Responsibilities

3.1 Supervisors

Ensure that all chainsaw operators are properly trained and competent.
Provide appropriate PPE to all chainsaw operators.
Ensure that chainsaws are properly maintained and in good working condition.
Enforce all safety procedures outlined in this document.
Conduct regular safety inspections of chainsaw operations.

3.2 Workers

Inspect the chainsaw before each use to ensure it is in good working condition.
Use the chainsaw only for its intended purpose.
Wear appropriate PPE at all times when operating the chainsaw.
Follow all safety procedures outlined in this document.
Report any unsafe conditions or equipment to the supervisor immediately.

3.3 Health and Safety Representative

Participate in safety inspections and audits related to chainsaw operations.
Assist in the investigation of any incidents or accidents involving chainsaws.
Provide feedback and recommendations on safety procedures and practices.

4. Potential Hazards and Risks

Hazard	Risk	Control Measures
Kickback	Serious injury from uncontrolled saw movement.	Use proper two-handed grip, maintain a stable stance, and avoid cutting above shoulder height.
Chain Breakage	Flying debris causing eye or laceration injuries.	Ensure chain brake is functioning correctly, use low-kickback chain, and avoid pinch points.
Excessive Noise	Hearing damage.	Wear appropriate PPE, including hearing protection, and take regular breaks.
Physical Strain	Muscle strains and sprains.	Use sharp chains, avoid forcing the saw, and maintain a clear work area.
Fuel Handling	Fire or explosion.	Ensure proper ventilation, use appropriate fuel mix, and store fuel in approved containers.
Falling Objects	Head or crush injuries.	Maintain situational awareness, use a spotter when necessary, and ensure a clear escape path.
Electrical Hazards	Electrocution or serious burns.	Inspect the work area for electrical hazards before starting work. Maintain a safe distance from overhead power lines.

5. Personal Protective Equipment (PPE)

Personal Protective Equipment (PPE) is essential for protecting workers from hazards associated with chainsaw operation.

Hard Hat: Provides head protection from falling objects and debris. Must meet ANSI Z89.1 standards.
Safety Glasses or Goggles: Protects eyes from flying debris and sawdust. Must meet ANSI Z87.1 standards.
- Ensure proper fit and seal to prevent debris from entering.
Gloves: Reduces the risk of cuts and abrasions. Leather gloves are recommended.
Safety Boots: Protects feet from cuts, punctures, and falling objects. Steel-toed boots are recommended.
Hearing Protection: Reduces exposure to harmful noise levels. Earplugs or earmuffs with a noise reduction rating (NRR) of 25 or higher are recommended.
Chainsaw Chaps or Pants: Provides leg protection from chainsaw cuts. Must meet ASTM F1897 standards.

PPE must be inspected before each use to ensure it is in good condition and functioning properly.

6. Equipment and Tools

All equipment and tools must be inspected before use to ensure they are in good working condition.

Chainsaw: Used for felling trees, limbing, and cutting wood. Ensure the chainsaw is appropriate for the task.
Chainsaw Sharpener: Used to sharpen the chainsaw chain. Follow manufacturer's instructions for proper use.
Fuel Container: Used to refuel the chainsaw. Ensure the container is approved for fuel storage.
Depth Gauge Tool: Used to measure the depth of the rakers on the chain. Essential for maintaining optimal cutting performance and reducing kickback.

Regular inspection and maintenance of equipment and tools is critical to safe chainsaw operation.

7. Pre-Job Requirements

7.1 Training and Competency

Training and Competency: All chainsaw operators must be properly trained and competent in the safe operation of chainsaws. Training must include: Chainsaw safety features, PPE requirements, Safe operating techniques, Emergency procedures

7.2 Pre-Job Briefing

Pre-Job Briefing: A pre-job briefing must be conducted before starting work. The briefing must cover: The scope of the work, Potential hazards, Control measures, Emergency procedures

7.3 Work Area Preparation

Work Area Preparation: The work area must be inspected and prepared before starting work. This includes: Clearing obstacles, Identifying hazards, Establishing a safe work zone

8. Safe Work Procedure Steps

Pre-Start Inspection: Inspect the chainsaw for any damage or defects. Check the chain tension, sharpness, and lubrication. Ensure all safety features are functioning properly.
Starting the Chainsaw: Start the chainsaw on a stable surface, away from flammable materials. Use the proper starting technique as outlined in the manufacturer's manual.
Proper Grip and Stance: Maintain a firm grip on the chainsaw with both hands. Keep your feet firmly planted and maintain a stable stance.
Cutting Techniques: Use a sharp chain and avoid forcing the saw. Let the saw do the work.
Kickback Prevention: Be aware of the potential for kickback. Avoid cutting with the upper quadrant of the guide bar.
Chain Lubrication: Keep the chain properly lubricated. Check the oil level frequently and refill as needed.
Shutdown Procedure: Shut off the chainsaw when not in use. Engage the chain brake and store the saw in a safe location.
Maintenance: Regularly inspect the chainsaw for any signs of wear or damage. Replace worn or damaged parts as needed.

9. Precautions and Safety Measures

Always wear appropriate personal protective equipment (PPE), including a hard hat, safety glasses, hearing protection, gloves, and chainsaw chaps.
Maintain a safe distance from other workers and bystanders.
Never operate a chainsaw when you are tired, distracted, or under the influence of drugs or alcohol.
Be aware of your surroundings and potential hazards, such as overhead power lines, uneven terrain, and falling objects.
Use extreme caution when working in wet or icy conditions.

10. Emergency Procedures

10.1 General Emergency Response

In the event of any emergency, immediately stop work and assess the situation. Ensure the safety of yourself and others. Provide first aid if necessary and contact emergency services.

10.2 Specific Emergency Scenarios

Chainsaw Cut: Activate the chain brake, stop the engine, and assess the injury. Provide first aid and call for emergency medical assistance.
Falling Tree or Limb: Move to a safe location, assess injuries, and call for emergency medical assistance.
Chainsaw Fire: Shut off the chainsaw, move to a safe location, and use a fire extinguisher to put out the fire. Call for emergency assistance.

10.3 Emergency Contact Information

In case of emergency, contact 911 or your local emergency number.

11. Incident Reporting and Investigation

All incidents, including near misses, must be reported to the supervisor immediately. A written report must be submitted within 24 hours.
