A week ago I had an accident that I never saw coming. At the end, what I learned is that even after doing treework for over 40 years there are always 'firsts'. Here's the setup. A 9/10" dbh boulevard ash. Nice head lean to the lay which was across the street with plenty of space for the canopy. The trunk had unusually large flare for such a small tree. Since I don't like putting a face in big flare I moved up about a foot. After cutting the pie I let the face piece drop on the ground. I did the cutting from the left side as I face the lay. The pie dropped on the ground by my left toe. Really small pie too. I put the back cut in leaving hinge wood so that it fell as soft as possible. When the face closed the stump broke the hinge and dropped to the ground. Right on top of the pie piece. I watched as the stump did a 'Tiddly Wink' smack down on the face shooting it off to my left. After I saw that the tree was on the ground I glanced left. Dang! The face piece had gotten shot 25' back down the street hitting the windshield of a parked car~~~it did a serious smack too! If that had hit a person they would have been off to the hospital. Maybe killed if it hit their face or even their chest. Right away I called my foreman. Then I took pictures and knocked on the door where the car was parked. The owner came out. He didn't flip out, which he sure had the right to! He had been rear-ended a few days before by a hit/run that turned out to not have insurance. Fortunately, the damage was only to the glass, not the body...whew! What could I have done differently? First, another crew member wanted to fell the tree but I asked if I could. No reason either. He would have done something differently. Make a ground level face. No trunk drop then. Clear the drop zone by kicking the face piece away. Block the car or have it moved. But, really, how much acreage do we really need? The result...I had a de-briefing with my foreman. The crew was all stunned! What are the chances of that happening?! In all my years I've never had this happen...it won't again! A few days later the crew I was on was going to fell a 20+" dbh basswood. Same setup as mine. After the face was cut the sawyer shoved it out and it landed right in 'my place' The guy on the front end loader [Avant] grabbed the face then hollared at me...making motions asking where I wanted it placed! Hahahaha! The ribbing has started. "One in a million" is what some people have said. Yup, I agree. Now I hope that no one else makes the same mistake.
