Abstract In the sector of occupational safety and health only a limited amount of studies are concerned with the conversion of inhalable to respirable dust. This conversion is of high importance for retrospective evaluations of exposure levels or of occupational diseases. For this reason a possibility to convert inhalable into respirable dust is discussed in this study. To determine conversion functions from inhalable to respirable dust fractions, 15 120 parallel measurements in the exposure database MEGA (maintained at the Institute for Occupational Safety and Health of the German Social Accident Insurance) are investigated by regression analysis. For this purpose, the whole data set is split into the influencing factors working activity and material. Inhalable dust is the most important predictor variable and shows an adjusted coefficient of determination of 0.585 (R2 adjusted to sample size). Further improvement of the model is gained, when the data set is split into six working activities and three material groups (e.g. high temperature processing, adj. R2 = 0.668). The combination of these two variables leads to a group of data concerned with high temperature processing with metal, which gives rise to a better description than the whole data set (adj. R2 = 0.706). Although it is not possible to refine these groups further systematically, seven improved groups are formed by trial and error, with adj. R2 between 0.733 and 0.835: soldering, casting (metalworking), welding, high temperature cutting, blasting, chiseling/embossing, and wire drawing. The conversion functions for the seven groups are appropriate candidates for data reconstruction and retrospective exposure assessment. However, this is restricted to a careful analysis of the working conditions. All conversion functions are power functions with exponents between 0.454 and 0.946. Thus, the present data do not support the assumption that respirable and inhalable dust are linearly correlated in general.

The Impact

Abstract Exposure to respirable dust (RD; the mass fraction of inhaled particles that penetrate to the unciliated airways) is a major health concern in a variety of workplaces. While the estimation of personal exposure is an essential step in protecting worker health from aerosol hazards, the traditional method for assessing personal exposure to RD, suggested by the National Institute for Occupational Safety and Health (NIOSH method 0600), requires equipment that is heavy, bulky, noisy, and has the need of frequent calibration. The ultrasonic personal aerosol sampler (UPAS) is a new personal sampling technology designed to address some of these drawbacks associated with traditional sampling methods. In this study, we field tested and evaluated the performance of the UPAS for assessing worker exposure to RD in a taconite mine. Mineworkers (n = 39) from various job categories were recruited to wear both UPAS and NIOSH 0600 samplers on a work vest to estimate time-weighted exposure to RD. A strong linear relationship was observed (NIOSH method 0600 = 1.06 (UPAS) −9.22 µg m–3, r2 of 0.72, and Pearson correlation coefficient of 0.854). None of the workers were exposed to a RD concentration above the Occupational Safety and Health Administration permissible exposure limit (5 mg m–3). A Bland–Altman analysis revealed that 72% of the valid UPAS samples agreed within ±25% of the traditional method mean. The impact of job category on the correlation of the methods was not statistically significant. This work suggests that the UPAS may present a viable alternative for assessing personal exposure to RD in the workplace.

Safety And Health

Pada tahun 2013 terdapat 2 kasus kecelakaan yang mengakibatkan 1 korban meninggal dunia. Begitu juga pada tahun 2014 sebanyak 1 kasus kecelakaan juga mengakibatkan 1 korban meninggal dunia dan beberapa kasus kecelakaan lain yang terjadi. Hal ini menunjukan bahwa masih tingginya tingkat kecelakaan yang diakibatkan oleh Bus Trans Metro Kota Pekanbaru. Tujuan dari penelitian ini adalah untuk mengetahui Penerapan Keselamatan dan Kesehatan Kerja Pada Pengemudi Bus Trans Metro Kota Pekanbaru. Jenis penelitian yang digunakan pada penelitian ini adalah observasional dengan pendekatan kuantitatif analitik dengan desain penelitian cross sectional. Jumlah Populasi yang diteliti sebanyak 100 yang terdiri dari seluruh pengemudi Bus Trans Metro Pekanbaru dengan jumlah sampel 80 orang. Teknik pengambilan sampel yang digunakan adalah dengan cara acak sederhana. Hasil uji bivariate menunjukkan bahwa pelatihan pvalue= 0,001, pengalaman kerja pvalue= 0,001, kondisi kesehatan pvalue= 0,688, stress kerja pvalue= 0,834, dan SOP pvalue= 0,002. Dari hasil uji bivariate dapat disimpulkan bahwa ada hubungan yang signifikan antara pelatihan , pengalaman kerja dan SOP dengan penerapan keselamatan dan kesehatan kerja pada pengemudi bus Trans Metro Kota Pekanbaru. Diharapkan kepada Dinas Perhubungan Kominfo Kota Pekanbaru, lebih meningkatkan kualitas kerja pengemudi dengan cara memberikan bekal pendidikan dan pelatihan dalam usaha pencegahan kecelakaan secara berjenjang dan berkesinambungan sesuai tugas dan tanggung jawabnya masing-masing.
