Chainsaw LanyardRedding—Cal/OSHA has cited Wright Tree Service of the West, Inc. for serious safety violations following an investigation into a fatal tree-trimming accident in Humboldt County near Weitchpec. The proposed penalties total $31,750.

On December 30, 2015, Kenneth A. Williams, a foreman with Wright Tree Services of the West, died while trimming a bay laurel tree on Rock Ranch Road. Although Williams was using a flipline lanyard to secure himself to the tree, it had only one point of attachment when regulations require two. Williams was killed when he accidentally cut the lanyard with the chainsaw he was operating and fell 54 feet.

Cal/OSHA’s investigation revealed the employer had failed to ensure that workers were using a second point of attachment to secure the worker when operating a chain saw in a tree. Also, workers’ clothing, equipment and procedures failed to meet safety standards.

“Tree work involves many hazards, and employers must develop and implement safety procedures and train their employees to prevent accidents,” said Cal/OSHA Chief Juliann Sum. “Most accidents can be prevented.”

Both citations in this case were classified as serious. Serious violations are cited when there is a realistic possibility that death or serious physical harm could result from the actual hazard created by the violation.

Failure to develop and implement appropriate safety procedures is one of the major causes of serious workplace injury and death in California. Accidents related to tree work can result in severe traumatic injuries and death. Twelve fatal accidents related to tree work have been reported to Cal/OSHA since May 2015.

Commonly reported accidents include falls, electrocutions, and those caused by falling objects. Most accidents can be prevented by recognizing and controlling hazards in advance as well as training employees on safe work practices and effective use of personal protective equipment. Cal/OSHA offers a fact sheet on tree work safety.
