This study aimed to characterize the use of five critical safety behaviors by tree fallers at different skill levels, and to test the feasibility of using a helmet camera to observe work activities directly in a remote environment. Small cameras were mounted on standard hard-hats. Video data were obtained for pairs of falters at four different skill levels, from beginning students to professional fallers. Critical action steps during tree episodes were coded and compared. Critical action steps for falters were successfully distinguished during work activities. Notable differences were observed among fallers in different skill categories and between individual fallers. This study found that the helmet camera worked well for observing faller work behavior, and that point-of-view video observation may be used to evaluate student loggers and training programs. We also found that professional fallers may have been exposed to increased hazard; care should be observed with helmet cameras designed for professionals.
