DESCRIPTION: (Applicant's Abstract) The goal of this research effort is to reduce morbidity and mortality due to wood dust exposure in small woodworking shops. This goal is consistent with Healthy People 2000 Occupational Safety and Health, Health Protection Objective 10.14 for providing assistance and consultation to assist small businesses in implementing safety and health programs for their employees. This goal also supports Occupational Safety and Health Research Needs which include developing "new measurement tools for assessing worker exposures" (Public Health Service, 1990). The specific aims of this research are: 1) To measure mean wood dust exposures in small woodworking businesses (3-20 employees) and to assess the level of dust controls (engineering, administrative, behavioral) as measured by a walk through survey; 2) To determine if an efficient industrial hygiene intervention program can be implemented in small woodworking shops; and 3) To assess the effectiveness of this industrial hygiene intervention by a standard public health strategy in a randomized controlled trial. The importance of this effort is underscored by the number of people employed as woodworkers, particularly the large proportion who work in shops that are small businesses with limited resources for effectively controlling wood dust exposures. The adverse health effects of these exposures include nasal cancer, allergic respiratory disease, and bronchitis, and may include allergic rhinitis and occupational asthma. A randomized controlled trial will be conducted to evaluate an intervention to reduce wood dust exposure in shops assigned to receive recommendations and technical assistance compared to shops receiving recommendations only for reducing dust levels. The shops receiving technical assistance will have a plan tailored to their individual shop environment which will include any appropriate engineering, administrative, and behavioral controls for reducing wood dust exposure. The sampling frame for this effort will include all woodworking shops within the Minneapolis-St Paul area; approximately 40-60 shops will be randomized. This sampling frame and the study procedures will be developed with the involvement of an industry Advisory Board of shop owners, workers, and union representatives. The primary outcome measure will be a comparison of the change from baseline in mean dust exposure levels for intervention and comparison shops at the final measurement of dust levels. A secondary outcome measure will compare levels of dust control based on the walk-through survey developed for this effort. In addition, the overall correlation between the work-through survey and mean dust levels (log scale) will be assessed.

描述：(申请者摘要)本次研究的目标 是为了减少因接触木尘而导致的发病率和死亡率 小型木工商店。这一目标与健康人是一致的 2000年职业安全与健康、健康保障目标 10.14提供协助和咨询，协助小型企业 企业在实施其安全和健康计划时 员工。这一目标也支持职业安全和健康 研究需求，包括开发“新的测量工具” 评估工人暴露“(公共卫生服务，1990)。 本研究的目的是：1)测量木材粉尘的平均暴露量 小型木工企业(3-20名员工)和评估水平 测量的粉尘控制(工程、管理、行为) 通过走访调查；2)确定高效的工业 可以在小木工中实施卫生干预计划 商店；以及3)评估这种工业卫生的有效性 标准公共卫生战略干预的随机化 对照试验。 这一努力的重要性从人数上得到了强调 受雇为木工，特别是在 商店是资源有限的小企业，可以有效地 控制木尘暴露。对健康的不良影响 这些暴露包括鼻癌、过敏性呼吸道疾病和 支气管炎，可能包括过敏性鼻炎和职业性哮喘。 将进行一项随机对照试验，以评估 减少商店木尘暴露的干预措施 与商店相比，获得推荐和技术援助 只收到关于降低粉尘水平的建议。商店 接受技术援助的客户将制定一项针对其客户的计划 个人商店环境，将包括任何适当的 减少木材的工程、管理和行为控制 暴露在粉尘中。这项工作的抽样框架将包括所有 明尼阿波利斯-圣保罗地区内的木工商店；大约 40-60家商店将被随机抽查。这一抽样框架和研究 将在行业的参与下制定程序 由店主、工人和工会代表组成的咨询委员会。这个 主要结果衡量标准是与基线的变化进行比较 干预和比较商店的平均粉尘暴露水平 粉尘水平的最终测量。次要结果衡量标准将是 根据走访调查比较粉尘控制水平 为这一努力而开发的。此外，两国之间的总体相关性 直通调查和平均粉尘水平(对数刻度)将为 评估过了。
