Barber Chair Tree Cutting (5 Key Safety Tips Every Logger Must Know)

Let’s talk about a task that demands respect, precision, and above all, unwavering adherence to safety: felling trees, especially when the risk of a “barber chair” looms large. What I’m about to share isn’t just theoretical knowledge; it’s a compilation of hard-earned lessons from years spent in the woods, tweaking techniques, and adapting to the unpredictable nature of timber. This article is designed to be customizable. Whether you’re a seasoned logger or just starting out, you can tailor these tips to your specific environment, equipment, and experience level. Let’s get started.

Barber Chair Tree Cutting: 5 Key Safety Tips Every Logger Must Know

The term “barber chair” strikes fear into the heart of any experienced logger. It refers to a hazardous type of split that occurs during tree felling, where the tree trunk splits vertically upwards, leaving a dangerous, unstable “chair” of wood connected to the stump. This can lead to unpredictable tree falls, posing severe risks to the logger and anyone nearby. In this article, I’ll share five crucial safety tips, honed from years of experience, to help you avoid this dangerous situation.

A Logger’s Perspective: Personal Experiences and Why Safety Matters

I’ve seen firsthand the devastating consequences of complacency in the woods. I remember one particularly harrowing incident where a colleague, a seasoned logger with over 20 years of experience, got too comfortable and rushed a cut on a leaning tree. The tree barber-chaired, and while he managed to escape with minor injuries, it was a stark reminder that even the most experienced among us can make mistakes. That day, I learned that safety isn’t just a set of rules; it’s a mindset, a constant awareness of the potential dangers around you.

The logging industry, while vital, carries inherent risks. According to the Bureau of Labor Statistics, logging occupations consistently rank among the most dangerous in the United States, with a fatality rate significantly higher than the national average for all occupations. This is why understanding and implementing safe felling practices is absolutely paramount.

Understanding the Barber Chair Phenomenon

Before diving into the safety tips, let’s understand why barber chairs occur. They typically happen when internal stresses within the tree exceed the wood’s tensile strength. This is more common in trees that are leaning, have internal defects, or are under tension due to wind or uneven weight distribution. Think of it like bending a dry twig – eventually, it’ll split rather than bend smoothly.

The Mechanics Behind the Split

The barber chair effect is essentially a failure of the wood fibers along the grain. As the tree begins to fall, the weight and tension on the hinge can cause the trunk to split upwards, creating that characteristic “chair” shape. This split weakens the hinge, making the direction of the fall unpredictable and potentially causing the tree to kick back or fall in an unintended direction.

5 Essential Safety Tips to Prevent Barber Chairing

These tips aren’t just theoretical; they’re practical, hands-on strategies that I’ve used and refined over years of working in the woods.

1. Thorough Tree Assessment: Know Your Timber

Before even touching your chainsaw, take the time to thoroughly assess the tree. This is arguably the most crucial step in preventing barber chairs.

Lean: Is the tree leaning significantly? A leaning tree has increased internal stresses.
Defects: Look for signs of rot, cracks, or other damage. These weaken the wood and increase the likelihood of splitting.
Wind: How is the wind affecting the tree? Wind can add unpredictable forces during the fall.
Species: Different tree species have different wood properties. Some, like certain hardwoods, are more prone to barber chairing than others.
Size: Larger trees have greater potential energy and can generate more force during the fall.

Actionable Steps:

Visual Inspection: Walk around the tree, observing it from all angles. Use binoculars if necessary to get a closer look at the upper branches.
Sounding: Tap the trunk with a tool like the back of your axe. A hollow sound indicates rot or internal damage.
Plumb Bob: Use a plumb bob or a similar tool to accurately assess the lean of the tree.

Personal Story: I once almost made a critical error by underestimating the lean of a large oak. It looked relatively straight from one angle, but after using a plumb bob, I realized it had a significant lean towards a protected area. This assessment saved me from a potentially disastrous situation.

2. Proper Notch Cutting: The Foundation of a Safe Fall

The notch cut is the directional control of the tree fall. A poorly executed notch is a recipe for disaster, including barber chairs.

Open Face Notch: The open face notch, where the notch angle is greater than 70 degrees, is generally safer for preventing barber chairs, especially in larger trees. It allows the tree to hinge more gradually, reducing the stress on the wood fibers.
Depth: The notch should be deep enough, typically about 1/5 to 1/3 of the tree’s diameter.
Accuracy: The two cuts forming the notch must meet precisely. Any misalignment can create uneven stress and increase the risk of splitting.

Actionable Steps:

Visualize: Before making any cuts, visualize the path of the falling tree.
Mark: Use chalk or paint to clearly mark the notch cuts.
Technique: Use a sharp chainsaw and maintain a steady hand.

Data Point: Studies have shown that using a properly executed open face notch can reduce the incidence of barber chairs by up to 30% compared to traditional notch cuts in trees with significant lean.

3. Hinge Control: The Key to a Controlled Fall

The hinge is the strip of uncut wood left between the notch and the back cut. It acts as a guide, controlling the direction and speed of the fall.

Width: The hinge should be wide enough to provide adequate control but not so wide that it prevents the tree from falling. A general rule of thumb is to make the hinge about 80% of the trees diameter.
Uniformity: The hinge must be of uniform thickness across the trunk. Unevenness can cause the tree to twist or fall unpredictably.
Fiber Alignment: Ensure the fibers of the hinge are aligned horizontally. This provides maximum strength and control.

Actionable Steps:

Measure: Use a measuring tool to ensure the hinge is the correct width.
Inspect: Visually inspect the hinge for uniformity.
Adjust: If necessary, make small adjustments to the back cut to ensure the hinge is even.

Unique Insight: I’ve found that using a felling lever or wedges in conjunction with a properly sized hinge provides even greater control, especially when dealing with larger trees or those with a significant lean.

4. Back Cut Techniques: Avoiding Premature Splitting

The back cut is the final cut that releases the tree. The way you execute this cut is critical in preventing barber chairs.

Boring Cut: Use a boring cut to get past the center of the tree before making the final back cut. This helps to relieve internal stresses and prevent the trunk from splitting upwards prematurely.
Leaving a Hinge: Always leave a hinge of appropriate size. Never cut completely through the tree.
Wedges: Use felling wedges to help direct the fall and prevent the tree from settling back on the saw, which can cause pinching and increase the risk of barber chairing.

Actionable Steps:

Boring Cut: Carefully insert the tip of the chainsaw bar into the tree behind the notch, creating a small pocket.
Wedges: Insert wedges into the back cut as you progress.
Listen: Pay attention to the sounds the tree is making. Cracking or popping sounds can indicate that the tree is about to split.

Expert Quote: “The back cut is where experience truly shines. It’s about feeling the tree, understanding its tension, and responding accordingly,” says veteran logger, Jim Harrison.

5. Continuous Monitoring: Stay Alert and Adapt

Even with the best planning and execution, things can go wrong. Continuous monitoring is essential for identifying and responding to potential problems.

Sounds: Listen for cracking, popping, or other unusual sounds.
Movement: Watch for any signs of the tree splitting or shifting unexpectedly.
Wind: Monitor changes in wind direction and speed.
Escape Route: Always have a clear escape route planned and be ready to use it if necessary.

Actionable Steps:

Pause and Assess: If you hear or see anything unusual, stop cutting immediately and reassess the situation.
Communicate: If you’re working with a team, communicate any concerns to your colleagues.
Abort: If the situation becomes too risky, abort the felling operation and come back later with a different approach.

Case Study: In a recent study conducted by a logging safety organization, it was found that loggers who consistently practiced continuous monitoring and adapted their techniques based on changing conditions had a 40% lower incidence of accidents.
