When the lumberjack felled the tree, one of the straps used to control the direction of the fall tightened and snapped. This released an enormous amount of energy, catapulting the strap toward the lumberjack and killing him instantly.
The incident serves as a reminder of how important it is to follow safety guidelines at work. Unfortunately, similar accidents happen more often than they should. It’s always necessary to use only certified straps in good condition with a guaranteed load capacity.
