Tree-Related Electrical Incidents: Us vs. Them

This article is a continuation of the series “Us Versus Them” (see sidebar), contrasting the nonfatal injuries of arborists and the public that occurred while using common arboricultural tools. Past articles have focused on chain saws, chippers/shredders, hand saws/pole saws and aerial devices/ladders. This is the first in the series to discuss arboricultural operations rather […]

Tree-Work Safety by the Numbers

Mathematics is not a field that sparks much interest among tree workers – or people in general. But the field of probability plays a role in just about everything tree workers do. If you knew that the odds of being severely injured performing a specific task were one in five, you might approach it with […]

Gloves: The Overlooked PPE

Personal protective equipment, or PPE, is what you need when everything else has gone wrong. You don’t need a helmet until your head has been impacted by an outside force, usually a branch stub. You don’t need cut-resistant leg protection until the saw kicks back into your leg. We wear PPE to keep the consequences […]

Tree Worker Safety Update By the Numbers: Another Us vs. Them

Another year, and arboricultural operations are still among the leading industrial activities for fatal and nonfatal injuries. Compared to all industries, tree workers have at least 15 times the fatality rate (Bureau of Labor Statistics 2020a) and three times the nonfatal rate (BLS 2018). You might take some comfort in the nonfatal rate being “only” […]
