In forestry, the term widowmaker or fool killer describes a detached or broken limb or tree top and denotes the hazards that such features cause, being responsible for causing fatalities to forest workers. The U.S. Occupational Safety and Health Administration describes widowmakers as, "Broken off limbs that are hanging freely in the tree to be felled or in the trees close by."
Widowmakers may pose a risk to equipment or personnel working under or around the tree. They can become dislodged by wind or during tree felling, and are responsible for 11% of all fatal chainsaw accidents. The U.S. National Institute for Occupational Safety and Health (NIOSH) offers ways to eliminate risks by avoiding working beneath widowmakers, knocking them down, or pulling them down with a machine.
