BI’s Article search uses Boolean search capabilities. If you are not familiar with these principles, here are some quick tips.

To search specifically for more than one word, put the search term in quotation marks. For example, “workers compensation”. This will limit your search to that combination of words.

To search for a combination of terms, use quotations and the & symbol. For example, “hurricane” & “loss”.

Tree-trimming deaths under investigation in California

Tree-trimming deaths under investigation in California

California’s Division of Occupational Safety and Health is investigating four tree-trimming workplace fatalities from the past six weeks and has launched a statewide safety awareness campaign for tree service companies, landscapers and other businesses.

The state’s Department of Labor Relations announced Wednesday that the four tree-trimming deaths now under investigation by Oakland-based Cal-OHSA include:

  • A worker in Mariposa County who was struck by a branch on Dec. 1
  • A worker in San Bernardino County who suffocated when dry palm fronds collapsed and trapped him on Dec. 4
  • A worker in Los Angeles County who fell approximately 60 feet when the branch he was tethered to broke on Jan. 6
  • A worker in Siskiyou County who was struck by the tree he was cutting to clear power lines on Jan. 9   

Cal/OSHA investigated nearly 70 accidents involving tree work, including trimming or removal services, in the two-year period between Oct, 1, 2014, and Sept. 30, 2016, the office said Wednesday in a statement. Nearly three out of four of these accidents — 74% — resulted in a worker hospitalization, and 12 of the accidents involved the death of a worker, the office reported. The major causes of tree trimming injuries and fatalities include falls, electrical shock, being struck by a tree branch, chainsaw lacerations, palm tree skirt collapses and ladder accidents.

Cal/OSHA cited the example of a tree service worker in Humboldt County who accidently cut the lanyard used to secure himself to a tree and fell 54 feet to his death on Dec. 30, 2015. The investigation found that the employer failed to ensure the worker was using a required second point of attachment in his security system while he was operating a chain saw in a tree.

As part of what is dubbed the “Tree Work Safety Emphasis Program,” Cal/OSHA inspectors throughout the state who observe unsafe tree trimming or tree removal operations will investigate possible violations and will respond to reports of unsafe operations, according to regulators.

“Cal/OSHA’s safety awareness campaign aims to protect the lives of tree service workers,” said Cal/OSHA Chief Juliann Sum in a statement. “Employers in this high-risk industry need to be aware of, and take steps to minimize, the hazards to their workers. We will cite employers that are not in compliance with safety requirements.”
