OSHA 29 CFR 1910.266
Logging Operations Standard - Forest Industry Safety Requirements
Last updated: November 6, 2025
Overview
OSHA 29 CFR 1910.266 is the comprehensive safety standard for logging operations in the United States. This standard addresses the unique hazards associated with commercial logging activities, including tree felling, limbing, bucking, skidding, loading, and unloading operations.
High-Risk Industry Statistics:
• Fatal injury rate 33 times higher than average for all workers
• Logging consistently ranks as the most dangerous occupation in the U.S.
• Primary hazards: Struck by falling trees/logs, caught in equipment, falls
• Most incidents occur during felling and manual processing operations
The standard applies to all timber harvesting operations with one or more employees engaged in felling or moving trees, and transporting or chipping logs. Given the extreme hazards inherent to forestry work, compliance with 29 CFR 1910.266 is critical for protecting logging crews from fatal and serious injuries.

Communication and Coordination
Effective communication systems are required for:
- Coordination between different work crews and equipment operators
- Emergency communication with supervisors and medical facilities
- Warning systems for hazardous operations like tree felling
- Daily safety briefings and hazard updates for all personnel
- Documentation of safety violations and corrective actions taken
Common OSHA Violations & Citations
Understanding frequent violations helps logging operations maintain compliance and avoid citations:
Most Frequently Cited Violations
- Inadequate or missing PPE (chainsaw chaps, hard hats, eye protection)
- Insufficient training documentation or failure to provide required training
- Equipment lacking ROPS/FOPS or damaged protective structures
- Improper felling procedures or inadequate retreat paths
- Missing or inadequate first aid supplies and emergency action plans
- Failure to maintain safe distances between operations
- Inadequate machine guarding or missing emergency stops
What OSHA Inspectors Look For
- Workers wearing proper PPE appropriate to their job tasks
- Current training records and documented competency evaluations
- Equipment inspection logs and maintenance documentation
- Safe work distances maintained between operations
- Adequate communication systems and emergency procedures
- First aid trained personnel on site with accessible supplies
- Proper felling notches and back-cuts on stumps
Implementation Checklist
Step-by-step guide to establishing a compliant logging safety program:
1. Develop Written Safety Program
- Create written logging safety plan addressing all 1910.266 requirements
- Establish procedures for job briefings and hazard assessments
- Document emergency action plans and evacuation procedures
- Define roles and responsibilities for safety compliance
2. Implement Training Programs
- Conduct initial safety training before employees begin logging work
- Provide equipment-specific training with competency evaluations
- Schedule annual refresher training for all personnel
- Maintain detailed training records with dates and topics covered
- Ensure first aid/CPR certified personnel on every crew
3. Establish Equipment Safety Protocols
- Implement daily pre-shift equipment inspection procedures
- Verify all machines have functional ROPS/FOPS and seat belts
- Establish preventive maintenance schedules per manufacturer specs
- Create equipment deficiency reporting and tag-out system
4. Ongoing Compliance & Documentation
- Conduct daily safety briefings and document attendance
- Maintain records of training, inspections, and incidents
- Perform periodic safety audits and hazard assessments
- Review and update safety program annually or after incidents
- Establish system for reporting near-misses and unsafe conditions
Frequently Asked Questions
Who needs to wear chainsaw chaps or protective pants?
All employees who operate chainsaws must wear cut-resistant leg protection that meets ASTM F1897 or equivalent standards. This includes fallers, buckers, and limbers. Workers who only limb with chainsaws (not involved in felling) must wear leg protection on the front of their legs from the thigh to below the top of the boot. Full wraparound chaps provide the best protection.
How far away must other workers be during tree felling?
The standard requires maintaining a distance of at least two tree lengths between employees during felling. This means if you're felling a 100-foot tree, other workers must stay at least 200 feet away. The faller must ensure the fall zone is clear before making the back-cut. Warning systems (hand signals, two-way radios, air horns) must be used to alert others before felling.
What training records must we maintain?
Training records must document: employee name, trainer's name, training date, topics covered, and competency evaluation results. Records must be maintained for each employee for the duration of employment plus 3 years. Include documentation of initial training, equipment-specific training, annual refresher training, and any corrective training provided. First aid/CPR certifications must also be kept on file.
Do we need a certified first aider on every logging site?
Yes, when the logging operation is located more than 3-5 minutes from emergency medical services, at least one employee trained in first aid must be available at each work location. This person must have current certification in first aid and CPR from a recognized training provider. First aid supplies must be readily accessible at each work site and maintained in a weatherproof container.
What's required for helicopter logging operations?
Helicopter logging has additional requirements beyond standard ground-based operations: operators must be trained in hooking and unhooking procedures, hand signals, and hover zone safety. Ground personnel must not approach the helicopter until signaled by the pilot. All personnel must wear high-visibility vests and hard hats. Load zones must be clear of non-essential personnel. Radio communication between pilot and ground crew is required.
How do we train new employees who have never logged before?
New employees must complete initial training before beginning any logging work. Training must cover: recognition of logging hazards, proper PPE use, equipment operation, safe work practices, and emergency procedures. New workers should work under close supervision of experienced employees until they demonstrate competency. Document all training provided, including on-the-job training and competency evaluations. Consider starting new employees on less hazardous tasks before advancing to felling or equipment operation.
Are seat belts required on logging equipment?
Yes, seat belts must be provided on all equipment equipped with ROPS (rollover protective structures). Operators must use seat belts when operating equipment with ROPS. This includes skidders, feller bunchers, loaders, and other mobile logging machines. Seat belts are critical to keeping the operator within the protective zone if a rollover occurs. Regular inspection of seat belt condition and proper anchoring is required.
What if we encounter a "widow maker" or hung-up tree?
Widow makers (dead limbs or tops lodged in trees) and hung-up trees present serious hazards. Workers must not work under widow makers or hung trees. Use mechanical equipment (skidder, excavator) to pull down hung trees from a safe distance. If mechanical equipment isn't available, use specialized techniques like directional felling of adjacent trees or pushing with poles - never climb or shake the tree. The area must remain off-limits until the hazard is eliminated.
