This article, titled "Understanding and Managing Hazards of Supported and Entangled Trees," discusses the complexities and risks involved in removing supported and entangled trees. Supported trees rely on another tree for structural support, while entangled trees are intertwined with another tree, creating additional structural complexities. The primary hazards of dealing with these trees include unpredictable behavior, mechanical stress release, compromised structural integrity, secondary impacts, and complex forces. The article provides an example case and emphasizes the importance of thorough training and awareness of tree conditions for safe arborist practice. It also outlines a systematic approach to mitigating the hazards, including risk assessment, developing a plan, using specialized techniques, obtaining necessary permissions, and continuous monitoring and adjustment. The article concludes by highlighting the essential training and qualifications for handling supported and entangled trees, such as ISA certification, ISA Tree Risk Assessment Qualification, training in advanced rigging techniques, proficiency in operating mechanical equipment, and field experience. By following best practices and maintaining vigilance, arborists can effectively manage these challenging tree situations and protect themselves and their crews. [Extracted from the article] |
