Timber Cutter Accident

For some reason my dad thinks what I do for a living is dangerous. He works for the timberlands division of a paper company and they have weekly safety meetings. This is one of the incidents they reviewed that he forwarded on to me.

Southworth Timber Cutter Accident

Employee : Calvin Jordon

Steel Toe leather boots (not chainsaw resistant)



Description of incident:

An experienced 53 year old timber cutter was working above a skid trail just below the top of a ridge approximately 150 yards from the log landing. He had felled a poplar saw timber tree and was in the process of limbing and topping when the accident occurred. The cutter decided to top the tree at a point where it tapered to a 10” top. The top was apparently under pressure because the cutter decided to buck it off by cutting from the bottom up. Part way through the cut, the saw kicked down and struck the cutters foot between the laces and the steel toe. The resulting injury was to the top of foot, severing a main artery. The cutter made his way part way back to the landing and was able to get the attention of the skidder operator, who signaled the rest of the crew for help. The crew immediately administered first aid by wrapping the foot and applying a tie down strap to maintain pressure. They also applied a tourniquet around his leg to slow the flow of blood to the foot. They called 911 and made arrangements to meet the local rescue squad about two miles away at a local convenience store. They transported the injured cutter to the convenience store where EMT’s administered aid and called for a life flight escort to Riverside Hospital in Columbus, Ohio. The early prognoses is good. The cutter is expected to recover with full use of his foot, but will continue to experience numbness due to damage to the nerves and artery.



Further investigation of the incident revealed that the drags on the chain were filed well below the top of the cutting teeth, which probably contributed to more severe “kick”. This is an unsafe practice that is sometimes used to make the saw cut more aggressively. All safety features on the saw were in place and working properly, including the chain brake. The timber cutter had been trained in chainsaw safety. The training program teaches that if a person follows safety procedures, they can usually prevent most accidents, even if one mistake is made. Accidents most often occur when multable mistakes are made. In this case, we had several factors that could have contributed to the accident; 1) Lack of chain saw resistant foot wear, 2) Improperly filed saw chain, 3) Placement of foot in harms way, 4) tip of saw bar not extended completely through wood. This is a good reminder of what can happen when “little things” pile up.

Very good quotes! Thanks for posting this. Hope he is doing well.
 
Laurence Gonzales writes about cumulative errors in his book Deep Survival. IN case you haven't heard, this should be on the MUST READ list along with Shigo, Blair and Jepson. You'll have a much better understanding about why some people survive accidents than others. Luck has very little to do with it.
 
No, there isn't anything written specifically about arbos. The book goes into all of the levels of survival thinking. A pretty complex subject that Gonzales makes accessible. We all face risks in our lives. Some people never even think about how they might deal with an emergency that would come up in a normal day. Then others, like arbos, work in risky environments. The survivors do things on many levels that prepares them for the eventual accident.

I think that this book is so good and so interesting to read, I'll make the same offer I have for the Tree Climber's Companion. If anyone doesn't think the book is easy to read or worth the money, I'll buy the book from them. It would give me a loaner to have to pass around to friends.
 
This brings up a couple questions in my mind:1)what percentage of people actually use a guage for rakers or do you just "eyeball" it(I've developed apretty good sense of the eyeball method from my logger days, but now I'm older and a little more safety minded I'm thinking about trying a guage-ANY FAVORITES?). 2)I know quite a few loggers who are wearing saw boots these days, but do any of you arbos take the time to put on these costly, clumsy things?
 
I use the Pferd file guide. It takes the depth gauges down every time the tooth is sharpened.

having aggresive depth gauges scares me. The saw gets too grabby, like an ankle biting dog.

The Husqvarna gauges are the best in my book. They lay on the specific tooth and will progressively lower the "raker" greater as the tooth recedes, maintaining cutting efficiency. They adjust each cutter to itself, thus making uniformity of cutter lengths less important. (the style which lays across the top of more than one cutter, parallel to the chain, requires great uniformity of cutter length to work correctly, and they do not lower the "rakers" progressively).

The Pferd file assembly Tom refers to basically does the same thing in terms of progressive lowering, but it has the problem, due to differing flexibility of the two separate files used simultaneously, of tending to lower the "rakers" too much and inconsistently if too much pressure is used either down and/or back. It's more pronounced on the smaller chains.

The Husky plates work well on Stihl chain too, though with somewhat less aggressive results than with the Oregon chain they were designed for.

(As for chainsaw protective boots, I have never tried them but would be hard pressed to move to anything more bulky than a hiking boot.)
Hope your last statement is a joke or provocation. I never start a chainsaw without them - I need my feet!

Thanks treebear, maybe we can move some of your thinking across the pond. You guys are so ultra-pro over there, is it mandatory or just a healthy desire for self preservation?
See you in Nashville? Minneapolis? Hawaii?
 
It is mandatory and also in my best interest. There are a lot of good chainsawproof boots on the market now and some of them are even comfortable and ok for climbing too. I´d really like to go to both Nashville and Hawaii but its a bit over the edge financially right now.

Got any contact info for these boots? I'm on a never-ending quest for the perfect footwear-safe, comfortable, lightweight, affordable, etc.
 
It would be interesting to find out what they meant by "experienced", timber cutter. I wonder if that meant 1 year, 6months or did he get his annual firewood by going into the bush a few times a year. It's good that he will be alright though.
A chainsaw, although somewhat safer to use then an axe, should be given the same consideration with regard to action and reaction as well as where we plant our feet.
Sometimes the biggest contributing factor in accidents is the victims state of mind.
As far as rakers, they are set at 25 thou. when new, but I find I like them to catch up to 20 thou. with progressive filing/grinding, where I find the chain cuts the best.
