Chainsaw Accidents: A Guide to Prevention and Safety

Chainsaw Accidents: A Guide to Prevention and Safety

Chainsaws are powerful and potentially dangerous tools that require proper precautions and safety measures. With sharp spinning blades powered by gas or electricity, it’s no wonder chainsaw accidents send over 36,000 people to emergency rooms each year. As someone who regularly uses a chainsaw to fell trees and clear brush, I know firsthand how hazardous these machines can be when handled incorrectly.

After my own close calls and witnessing other gruesome injuries over the years, I decided to create this comprehensive guide to chainsaw safety. My goal is to educate fellow chainsaw operators on accident prevention, proper use and handling, protective gear, and other vital safety tips. With the right knowledge and precautions, these invaluable yet risky tools can be operated with minimized risk of injury.

What are Chainsaw Accidents?

Chainsaw Accidents: A Guide to Prevention and Safety

Before exploring how to prevent chainsaw accidents, it helps to understand what types of accidents occur and the common injuries inflicted. Chainsaw mishaps can happen in various ways, but kickback, pushback, and pull-in are the main forces that cause injuries and fatalities.

Types of Chainsaw Accidents

Kickback is the most common and dangerous type of chainsaw accident. This occurs when the moving chain near the upper tip of the guide bar touches an object or gets pinched, causing the bar to be forced back toward the operator suddenly with tremendous force. I’ve personally had my saw kick back dangerously close to my face, which could have resulted in devastating facial injuries.

Pushback happens when the chain on the bottom of the guide bar gets pinched, pushing the saw back away from the operator. This can make you lose control but is less violent than kickback.

Pull-in occurs when the chain gets lodged while cutting, pulling the chainsaw forward and throwing the operator off balance. This often leads to contact with the moving chain.

Common Injuries from Chainsaw Accidents

While chainsaw injuries can range from minor to fatal, these are among the most prevalent:

  • Cuts and lacerations: The fast-spinning chain is designed to aggressively cut through wood, so any accidental contact inevitably results in deep gashes that require stitches or even surgery to repair.
  • Amputations: When kickback or other forces bring limbs in contact with the sharp chain, it can easily sever fingers, hands, arms and legs. Tragically, some accidents result in partial or complete amputation of these body parts.
  • Hearing loss: Without proper ear protection, prolonged exposure to the loud noise from a chainsaw engine and cutting chain can cause permanent hearing damage over time.
  • Muscle fatigue: Operating a heavy, powerful chainsaw and making repetitive motions during cutting can strain muscles in the arms, back, shoulders and hands leading to chronic issues.
  • Carbon monoxide poisoning: Gas-powered saws release carbon monoxide that can be dangerously inhaled in enclosed spaces without adequate ventilation.

How to Prevent Chainsaw Accidents

While chainsaw accidents may seem unavoidable, there are several effective precautions that every user should take:

Choosing the Right Chainsaw

Investing in a suitable saw for your specific needs and skill level helps mitigate risks. Consider the following:

  • Size and power: Larger chainsaws with 60cc engines or more are designed for heavy duty logging and felling large trees. Their power increases kickback danger. For routine use around a small farm or cutting firewood, a compact 30-40cc saw is ideal.
  • Safety features: Look for crucial features like chain brakes, anti-vibration handles, chain catchers and low-kickback chains. Don’t buy a chainsaw without them!
  • Maintenance: Does the saw require intensive maintenance and frequent sharpening that will be costly over time? This should factor into your decision.

Proper Use and Handling

Once you have a suitable chainsaw, using proper form and technique will go far in preventing accidents:

  • Read the manual: Every chainsaw model has specific handling instructions owners must read to understand safe operation before use.
  • Use two-handed grip: Firmly grip the rear handle with your dominant hand and the front handlebar with your other hand to maximize control. Never operate a chainsaw using just one hand.
  • Adopt proper stance: Stand with your dominant side slightly behind to brace for potential kickback. Feet should be shoulder width apart with balance and mobility.
  • Avoid kickback: Be extremely cautious of the guide bar tip contacting objects. Also don’t cut with the upper quadrant of the bar tip when possible.
  • Use safe cutting technique: Let the engine gain full speed before cutting, don’t overreach or cut above shoulder height, use extreme caution cutting small brush and limbs.

Personal Protective Equipment (PPE)

Chainsaw-resistant chaps, safety helmet, goggles, ear protection, steel-toe boots, and cut-resistant gloves form your last line of defense against injury. Don’t ever operate a chainsaw without wearing:

  • Chainsaw chaps: These are made of cut-resistant fibers that clog the chain upon contact to stop it before it cuts into your legs. I’ve had chaps save me from potentially devastating leg injuries.
  • Helmet with screen: Safety helmets protect your face and head from falling debris and deflect sawdust and chips while cutting. Those with mesh visors provide additional protection.
  • Eye protection: Sturdy polycarbonate goggles prevent eye injuries and blindness that could occur from wood chips and sawdust entering your eyes while sawing.
  • Hearing protection: Make sure to wear earplugs and earmuff style protectors when operating a chainsaw to prevent hearing damage from the loud noise.

Chainsaw Safety Tips

Beyond accident prevention and protective gear, following these vital safety tips will also reduce your risk of injury:

Chainsaw Maintenance

Like any power tool, proper maintenance is crucial for safety and performance. Be sure to:

  • Inspect regularly: Check for damaged, loose or missing parts before each use to identify potential hazards.
  • Keep chain taut: A loose chain can derail or increase the risk of kickback. Refer to your model’s guide for proper chain tensioning.
  • Sharpen the chain: A dull chain requires more force during cutting, increasing fatigue and risk of kickback due to resistance. Sharpen regularly.
  • Store securely: When not in use, keep in a high, dry place out of reach of children and unauthorized users.

Safe Work Environment

Creating a safe workspace helps avoid environmental hazards:

  • Clear the area: Remove debris, rocks, branches and anything else that could interfere with cutting and safe footing prior to starting work.
  • Be aware: Regularly survey your surroundings and maintain focus. Be alert for any safety issues that arise as you cut.
  • Mind your footing: Clear away brush and objects that could cause you to trip or lose balance while operating your saw.

Training and Experience

There’s simply no replacement for proper chainsaw training and experience:

  • Seek training: Take a class or have an experienced professional walk you through safe chainsaw handling prior to use. Even as an experienced operator, periodic training is wise.
  • Learn from others: Observe and learn techniques from seasoned chainsaw operators before attempting any significant cutting work on your own.
  • Practice: Use a practice log or designated cutting area to develop confidence and skill with your saw before tackling any actual projects.
  • Don’t overextend yourself: Know your limits based on your skill level. Don’t attempt complex or hazardous cuts beyond your experience. Seek help when needed.

Chainsaw Accident Statistics

Looking at sobering chainsaw injury data further enforces the importance of safety:

Chainsaw Injury Rates

According to emergency room records, an estimated 36,400 people in the U.S. suffered chainsaw injuries in 2021 alone. That amounts to over 100 serious injuries per day. Studies show:

  • Most are preventable: A vast majority – around 90% – could have been avoided with proper safety precautions.
  • Potentially disfiguring/disabling: Over 30% of injuries caused disfigurement, permanent impairment, or disability. Many required reconstructive surgery.
  • Common injuries: Nearly half were injuries to hands and arms. About 1 in 5 were leg injuries, and 1 in 10 were to the head, face or neck.

Fatal Chainsaw Accidents

While less frequent than non-fatal injuries, fatalities from chainsaw mishaps still occur regularly. The leading causes include:

  • Kickback: When kickback brings a spinning chain in contact with the head, face or neck area, it often severs major blood vessels or causes brain trauma resulting in death.
  • Falling trees: Improper tree felling techniques can send a tree falling in an unintended direction directly onto the operator.
  • Electrocution: Contact with overhead power lines while operating a chainsaw leads to electrocution for some each year. Proper situational awareness could prevent these deaths.
