We utilized job safety analysis (JSA) and hazard identification for work accident prevention in Para rubber wood sawmills, which aimed to investigate occupational health risk exposures and assess the health hazards at sawmills in the Trang Province, located in southern Thailand.
We conducted a cross-sectional study which included a walk-through survey, JSA, occupational risk assessment, and environmental samplings from March through September 2015 at four Para rubber wood sawmills.
We identified potential occupational safety and health hazards associated with six main processes, including: 1) logging and cutting, 2) sawing the lumber into sheets, 3) planing and re-arranging, 4) vacuuming and wood preservation, 5) drying and planks re-arranging, and 6) grading, packing, and storing. Working in sawmills was associated with high risk of wood dust and noise exposure, occupational accidents injuring hands and feet, chemicals and fungicide exposure, and injury due to poor ergonomics or repetitive work.
Several high-risk areas were identified from JSA and hazard identification of the working processes, especially high wood dust and noise exposure when sawing lumber into sheets and risk of occupational accidents of the hands and feet when struck by lumber. All workers were strongly recommended to use personal protective equipment in any working processes. Exposures should be controlled using local ventilation systems and reducing noise transmission. We recommend that the results from the risk assessment performed in this study be used to create an action plan for reducing occupational health hazards in Para rubber sawmills.
我们运用作业安全分析（JSA）和危害识别来预防三叶橡胶木锯木厂的工伤事故，旨在调查泰国南部董里府锯木厂的职业健康风险暴露情况并评估其健康危害。
我们开展了一项横断面研究，于2015年3月至9月在四家三叶橡胶木锯木厂进行了巡视调查、JSA、职业风险评估以及环境采样。
我们识别出与六个主要工序相关的潜在职业安全和健康危害，包括：1）伐木和切割，2）将木材锯成板材，3）刨平和重新排列，4）吸尘和木材防腐处理，5）干燥和板材重新排列，以及6）分级、包装和储存。在锯木厂工作与木材粉尘和噪音暴露、手脚受伤的职业事故、化学品和杀菌剂暴露以及因人体工程学不佳或重复性工作导致的伤害的高风险相关。
通过JSA和对工作流程的危害识别确定了几个高风险区域，特别是将木材锯成板材时木材粉尘和噪音暴露较高，以及木材撞击时手脚发生职业事故的风险。强烈建议所有工人在任何工作流程中使用个人防护设备。应使用局部通风系统并减少噪音传播来控制暴露。我们建议将本研究中进行的风险评估结果用于制定减少三叶橡胶锯木厂职业健康危害的行动计划。
