Abstract

Previous studies have investigated the health hazards caused by exposure to the noise of heavy equipment used at construction sites. Korea's Ministry of Land, Infrastructure, and Transport operates a registration system for construction machinery, and regular safety inspections are mandatory. Although workers inspecting construction machinery vehicles are exposed to unwanted noise, no noise exposure assessment has been made regarding these workers in Korea. The time-weighted average (TWA) daily average noise exposure level among construction machinery inspectors at 18 inspection centers was 75.3 dB(A). Among the inspection steps, the exhaust gas inspection step was found to exhibit the highest noise exposure level, up to 100 dB(A). In Korea, if the noise level of a workplace exceeds 85 dB(A) as a TWA, workers are required to undergo special medical examinations. This study found that special medical examinations were required for two of the 18 target inspection centers (approximately 115 workers) as the 8-hour TWA noise level exceeded 85 dB(A). Therefore, regular noise exposure assessment and special medical examinations for noise are required to prevent inspectors from developing hearing disorders due to noise exposure.

大韩民国检查建筑机械车辆工人的噪声暴露评估。

以往的研究调查了暴露于建筑工地使用的重型设备噪声对健康造成的危害。韩国国土交通部对建筑机械实行登记制度，并强制要求定期进行安全检查。虽然检查建筑机械车辆的工人会接触到不必要的噪声，但韩国尚未对这些工人进行噪声接触评估。18 个检查中心的建筑机械检查人员的时间加权平均（TWA）日均噪声暴露水平为 75.3 dB(A)。在检查步骤中，废气检查步骤的噪声暴露水平最高，达 100 dB(A)。在韩国，如果工作场所的噪声水平超过 85 dB(A)（TWA），工人必须接受特殊体检。本研究发现，在 18 个目标检查中心中，有两个中心（约 115 名工人）需要进行特别体检，因为 8 小时 TWA 噪音水平超过 85 dB(A)。因此，需要定期进行噪声暴露评估和噪声特别体检，以防止检查员因暴露于噪声而出现听力障碍。

期刊介绍： About the Journal Annals of Work Exposures and Health is dedicated to presenting advances in exposure science supporting the recognition, quantification, and control of exposures at work, and epidemiological studies on their effects on human health and well-being. A key question we apply to submission is, "Is this paper going to help readers better understand, quantify, and control conditions at work that adversely or positively affect health and well-being?" We are interested in high quality scientific research addressing: the quantification of work exposures, including chemical, biological, physical, biomechanical, and psychosocial, and the elements of work organization giving rise to such exposures; the relationship between these exposures and the acute and chronic health consequences for those exposed and their families and communities; populations at special risk of work-related exposures including women, under-represented minorities, immigrants, and other vulnerable groups such as temporary, contingent and informal sector workers; the effectiveness of interventions addressing exposure and risk including production technologies, work process engineering, and personal protective systems; policies and management approaches to reduce risk and improve health and well-being among workers, their families or communities; methodologies and mechanisms that underlie the quantification and/or control of exposure and risk. There is heavy pressure on space in the journal, and the above interests mean that we do not usually publish papers that simply report local conditions without generalizable results. We are also unlikely to publish reports on human health and well-being without information on the work exposure characteristics giving rise to the effects. We particularly welcome contributions from scientists based in, or addressing conditions in, developing economies that fall within the above scope.
