Importance of Chainsaw Safety

A chainsaw is probably one of the most dangerous tools you are likely to store in you back shed, so it’s imperative that we consider that safe way to operate them before use. A chainsaw is a mix of rapidly moving parts and a whirling chain studded with razor-sharp teeth. The original chainsaw was designed specifically to cut through bone in hospitals. Today’s models are much more powerful and can easily remove an arm or a leg in an instant if you don’t pay attention to what you are doing. Using a chainsaw for an extended period is hard work and can cause fatigue which increases the operator’s risk of injury even further. Some people even remove chain depth gauges to increase cutting speed which increases the risk of chainsaw kickback, and other long-term health consequences from poor postures and high levels of vibration and noise. Never underestimate the danger of working with a chainsaw. Fortunately, the chainsaw itself is now being made with built-in features that can save your life and protect you from bodily injury. So, now let’s look at 10 of them that are available on most chainsaws. Some have additional ones as well. However, the ones, we will list are the most common.


For a quick reference check out this infographic which gives the 5 key Safety Features of a chainsaw

ChainSaw Safety - INFO GRAPHIC

10 Safety Features on a Chainsaw

Chainsaws are made up of 5 main components, a motor and clutch, a bar where a chain rotates around and of course the chain with the teeth that do the actual cutting. Most of them you find on the market today are gasoline powered. Electrically powered ones are available both corded and battery powered. Each chainsaw is a little different from the rest. Placement of the various features and items can vary greatly between makers and even those made by the same company. Since safety is always, our first concern we will look at the most common ones found on chainsaws today.

Front Hand Guard

This fits on the front of the engine housing and it protects the hands from a chain that breaks and flies backward. It will also to a limited extent protect you from flying splinters as well.

Chain Brake

Just what it implies, it stops the chain instantly. It operates while the motor is still running and lets you change position for cutting in a different position.


Again, this is self-explanatory. Like the sheath of a knife, it is used to cover the blade of the chainsaw when you are carrying it from place to place. A chainsaw’s teeth on a properly cared for chainsaw are razor sharp. If you or someone else bumps up against it can result in cuts and torn clothing.

Throttle Trigger Lockout

Is another feature that is designed to allow for control and safety? Releasing the trigger stops the blade immediately. This is the primary way to control the 3,000 – 7,000 RPM motor that drives the chain.


The inertia of a sudden upward movement of the chainsaw trigger this feature and it can be also engaged when the left-hand moves forward on the hand brake. So, the short of it is that you are protected from kickbacks and other unforeseen sudden movements including a fall.

Chain Catcher

If your chain breaks, even with PPE you can suffer injury. A chain catcher stops the chain from coming back at you. It is a simple device that you can see if you look at the underside of your chainsaw. It is an l shaped tapering piece that if the chain snaps the teeth will catch on it and prevent the chain from flying off at you.

Kickback Guard

Mounted in front of the front handle it activates when the operator rotates his left hand forward. This then stops the chain from moving. Often kickback guard is part of an inertia mechanism that activates if the left hand is out of position. The upward movement caused by kickback triggers the chain brake.

Spark Arrester

Gasoline engines put out smoke and sparks. You don’t want to catch a face full of them. You also don’t want sparks when saw dust is flying about. This makes for an explosive combination. The same is true when you are cutting a firebreak in the woods during a forest fire, as you do not want to complicate matters. The spark arrester comes in a number of forms and the simplest is a wire-mesh that stops sparks from making it past the muffler.

Rear Handle Guard

This provides the necessary control and lets you halt the motion of the chainsaw if it kicks. When you start the chainsaw, it also provides a way to insert your foot and start the chainsaw safely. What you see in the movies where the character airdrops the chainsaw while pulling the starter cord is a recipe for amputation of a limb if things go south. Placing the chainsaw on the ground and stepping into it is the recommend approach. See the safety videos that are in another section of this article

On/Off Switch

The ultimate safety feature, click it off and no spark can get to the motor. The motor stops and the chain’s movement are arrested. You also need it in the on position just to start things running.

Electric Chainsaw Safety

electric chainsaw safety

Just because its electrically powered doesn’t mean you have less to worry about. You have more. With the lighter weight, you forget how powerful the motors are and you can get careless. This can endanger your life. However, in addition, you have the same dangers of a regular chainsaw. Then, you can also add electrocution to the list as well. Cutting through your electrical cord is a quick way to meet your deity if you do not take the proper precautions. Ground Fault Interrupters (GFI) are a good idea and a second person managing your cord is another. Wearing the right type of protective gloves is also good idea along with your boots being insulated is also recommended.

Is an Electric Chainsaw more dangerous than a Gas Chainsaw?

Great question! Well, any chainsaw is dangerous: You can experience kickback (when the bar and chain fly off your cutting surface and take aim at your leg, chest or head), and you can suffer lost eyesight from kicked up debris – but an electric saw carries its own risks.

Electric saws channel a high-amperage electric current when they’re powered on. While it takes just 0.1 to 0.2 amps to kill a person, the average electric chainsaw pumps out anywhere from 9 to 20 amps and loads of volts (yikes). Factor in the whirling cutters, which are only being controlled by your stance and arm strength, and you can see how some serious accidents might result. So how can you insulate yourself (pun intended) from becoming the victim of an electric chainsaw injury? Keep reading for some simple but helpful operating tips.

Insulate, Separate, and Always Hook Up to a GFCI Outlet

Dangerous or fatal electric shock occurs when your body becomes the shortest route for electricity to travel within a circuit. The risk is exponentially increased when you come in contact with highly conductive grounds, like wire, rebar, water, or more importantly in this case, wet wood or mud. To prevent grounding your body when using your electric saw, it’s highly recommended you wear a pair of rugged, rubberized boots. Your boots’ soles should be free of metal riveting and you should check to make sure no metal bits or nails are buried in your soles beforehand.

A good set of heavy-duty, insulated work gloves will help further protect you from electric shock. You can pick up a decent pair for $25 to $50. It’s always a good idea to wear gloves when operating a chainsaw, so this should be a no-brainer. Lastly, if your saw is corded, keep an eye out. Keep the cord away from your blade, and have a buddy handle your cord if they’re available. Make sure you’re hooked up to a Ground Fault Circuit Interrupter outlet. Known as GFCI or GFI, this type of outlet will trip your breaker and cut power if it detects electricity is being channeled through an alternative path – like your body or a source of water. Speaking of water…

Never Operate Your Electric Chainsaw in Wet Conditions

Obviously, working outdoors will inherently mean that you may be around sources of water, and that may be okay. Avoid the coy pond and creek and be mindful of where your power cord’s resting. If it’s raining, could rain, or just rained, don’t operate. It’s not worth the risk. Electric saws’ motors have exposed vents to dissipate heat – all it takes are a few drops of water to short your saw and give electricity an alternative path down your hand and through your chest.

Treat Your Electric Saw Like It’s Always On

Electric is a silent, smell-less, tasteless killer. It’s obvious when any old gas chainsaw’s running, thanks to loud combustion and exhaust. But an electric chainsaw gives away few hints that it’s powered up and ready to go. Treat your saw like it’s always on, and keep it separated from any conditions that might cause a short or shock – you have no reason not to be this cautious.

When it’s time to service your saw, make sure it’s unplugged if corded, or make sure the battery’s removed if cordless. Give the operating handle or power buttons a few presses (in a safe manner) just to be sure. Once you’re done cutting or servicing your saw, make sure it’s dry, unplugged with the battery removed, and store it in a dry place. Like we said earlier, it takes just a few drops of water to cause a short and dangerous electrical shock when you go to cut that first log.

Essential Chainsaw Safety gear

Just having a chainsaw with all the latest safety features doesn’t mean you’re now safe from injuries. You need to wear your own safety gear also know as Personal Protective Equipment or PPE. In medieval days of old Japan, a Samurai unlike the depictions in the movies wore full armor when they took the field of battle. The Samurai sword was and still is the sharpest length of metal ever seen. So, when facing someone using such an instrument you need to have the right equipment in order to survive.

Your chainsaw is many times more powerful and would shred a Samurai’s armor as if it were paper. So, what do you think would happen if you slip? This is why the government, industry and private researchers perform an ongoing search for new materials that can protect you. There are some amazing fabrics and stuff out there that can stop a chainsaw in its tracks without you losing an arm, leg, and your face. Let’s now break safety gear down for you item by item and explain their use.

Protective Chainsaw Suit

chainsaw safety PPE

A full jumpsuit-type protective suit is often the first choice for the pro that uses a chainsaw in their daily activities. It is often mandated by company policy, as it cuts on insurance premiums and insurance companies are the big kid on the block, as they don’t want to payout on a policy covering the loss of an arm, leg, and eye. It also provides total coverage that just chaps, chainsaw safety pants, and gloves don’t cover. The major drawback of these suits of body armor are that they can be hot during summer work, they can be uncomfortable and restrict movement somewhat. However, protective gear will save your life.

Chainsaw Safety Gloves

Hand injuries, along with leg injuries are the most common type of injury chainsaw uses befall. This being the case it is so critical that you are always using appropriate gloves that can help your hands from being squashed by wood or cut by the sharp teeth on the chainsaw blade. Good gloves can also help reduce the vibration your hands and arm feels while using your saw, which can make a real difference.

Chainsaw Safety Chaps and Pants

If you are working aloft or in hot climes, safety chaps and pants will save you from losing a leg or bleeding out before help can arrive. You will see demos in our video section where a live chainsaw goes up against the materials and though the clothing is unusable the person inside is unharmed. The Late Show once had a demo where the host let a chainsaw wielding guest have a go at him. The material was shredded but the star within was still able to crack jokes. You might be more in the mood to hoist a few cold ones when yours keeps your leg from coming off. The most common area people are injured when using a chainsaw is from their thighs to feet, safety chaps will help protect you from injuries over most of this part of your body.

Chainsaw Safety Boots

A lot of chainsaw work involves logs that are on their side. Things wiggle and wobble so; many use their foot to hold things still while they work. You know what can happen next. Safety boots need to be tough leather and steel capped or steel toed and have a high impact rating, ideally you can get specific Chainsaw protective boots which are designed to guard against foot injuries from chainsaws.

Chainsaw Safety Helmet

After you’ve seen the videos on “Kickback”, do you really want to be using a chainsaw without proper headgear? They keep your brains inside your noggin instead of letting them spray all over the work area. Anyone who uses a chainsaw without headgear should be banned from working with them in this writer’s opinion.

Do I need safety glasses too?

Yes, sawdust and splinters can get past the safety shield. It might be thrown in your face by your chainsaw or from someone else’s working next to you. You only get two eyes at birth and the technology to build a Bionic Man isn’t here yet. So, there is no replacement for what nature provides. A splinter can travel at the speed of Cub’s Pitcher’s fastball and you can be blinded in an instant.

Chainsaw Safety Training Available

One of the most important things for you to do in order to be properly trained on safety and operation is to get educated. We have a number of videos in a later section that covers this but there is no substitute for getting hands on training with the supervision of someone who knows how to do it right. Many home supply centers and hardware outlets will run free classes on the proper use and safety of chainsaws. This is especially true up in the Northwest part of the country where logging is still a major industry. They are also held in the “Tornado Belt” in the Mid-West. Community colleges offer classes as well. In rural areas, the County Farm Bureau and other state agencies, as well as OSHA, have materials that you can use.

This is just a sample of what you can find from online sources:

Checklists are another way to do things in the proper manner and order. We will repeat some of the information in a later section of this article as it pertains to a number of areas in chainsaw usage. We have given you links to some sample ones that cover everything from oiling the chain to what PPE you should be wearing and points you to the specifications and the why for them as well.


UDEMY has a number of chainsaw safety training courses you can take as well.

The Husqvarna website is also a useful source of info also.

In the next section, we have a number of videos that go into extensive detail on not only safety but also the care and feeding of your chainsaw as well.
