Exposure to Hand-Arm Vibration (HAV) in Forestry: An Empirical Review
摘要
Exposure to hand-arm vibration (HAV) in forestry is almost exclusively related to operating a chainsaw. The problematization of vibration arose with the mass adoption of chainsaws for forestry work in the 1960s. Terms like “vibration white finger” refer to symptoms and conditions caused by exposure to HAV classified today under Raynaud's syndrome. To battle health issues caused by HAV, exposure calculation methods were established, and multiple legislative measures were issued. Although the ergonomics and overall safety of chainsaws improved immensely since the 1960s, exposure to chainsaw-induced HAV remains a relevant factor for the occupational health of chainsaw operators. This paper aims to compile the latest studies on this topic and present it concerning known influential factors and protective measures.
