Abstract

Lead is a heavy metal that can pose various health risks to humans. One of the effects of lead exposure is the inhibition of the delta-ALAD enzyme which plays a role in the heme synthesis process. Blood lead levels and delta-aminolevulinic acid dehydratase (ALAD) activity are considered biomarkers of lead exposure and lead toxicity respectively. The inhibition of ALAD can cause in accumulation of ALA in urine and also inhibit the heme synthesis pathway that plays a role in hemoglobin production. The present study was designed to investigate the association between the BLLs and the heme synthesis process, which is detected by the accumulation of urinary ALA (ALA-U) and decreasing hemoglobin, in paint industry workers from Indonesia. A total of 52 paint industry workers participated in this study. Blood lead was measured using ICP-MS and ALA-U was measured using spectrophotometer method. Mean blood lead was 4.213±1.6 mg/L; and 17 workers (32.7%) crossed the recommended level of 5 mg/L. Mean urinary ALA level was 3.712±2.5 mg/L; and 11 workers (11.54%) crossed the normal level of 6 mg/L but still classified as acceptable. Mean hemoglobin level was 15.273±1.03 g/L. The correlation between the BLL and ALA-U was found to be positive but not significant. Meanwhile, the correlation between the ALA-U and the hemoglobin levels was found to be negative but also not significant.

Abstract

Lead-based paint is a main source of lead exposure to paint industry workers and causes an imbalance of Reactive Oxygen Species (ROS) and antioxidants, causing a genotoxic effect. Pb in the blood (PbB) level and DNA damage are frequently used as exposure and effect biomarker of lead. The purpose of this study to determine the relationship between PbB level and DNA damage due to occupational lead exposure in paint industry workers. The research design uses a cross-sectional epidemiological study involving 52 workers from three paint manufacturers in Indonesia. Blood samples were taken for PbB analysis using ICP-MS, while DNA damage was analyzed using the Comet Assay method. The PbB average obtained was 4.36±1.60 µg.dL-1, where 17 workers (32.69%) exceeded the safe limit value of PbB (5 µg.dL-1). Meanwhile, the influential factors of PbB are the working period and alcohol consumption (p=0.029). The level of DNA damage was represented as Tail DNA (%), and the average was 9.62±0.19 %. All respondents in this study were categorized as under low damage (Class 2). There was no significant relationship between PbB and Tail DNA (%) and has a negative correlation (p=0.878; r=-0.022). The study concludes that there was no difference in Tail DNA (%) between PbB ≥ 5 µg.dL-1 and PbB < 5 µg.dL-1 (p=0.876). It means that lead exposure in this finding has not reached a level that can significantly cause DNA damage. However, it is necessary to monitor PbB levels in workers to minimize genotoxic or other effects.

Abstract

This study was conducted to analyze the potential for human error that can cause workplace accidents in the cement industry of PT.X. The study was conducted by conducting observations, interviews, and distributing questionnaires in the mining area and production area. Questionnaires were distributed to 96 people who were mining heavy equipment operators and production operators. The research method used through Human Reliability Analysis with the Hierarchial Task Analysis (HTA) method, knowing the types of errors that occur using the SHERPA method, then calculating the probability of human errors that occur with the HEART method. Based on the results of research using the SHERPA method, the most common types of errors in mining areas and production areas are action errors (60,25%). The type of error that occurs is due to negligence in using personal protective equipment and the work process is not completed properly. Based on research using the HEART method, the greatest opportunity for human error in the mining department is cleaning with dozer with a value of 1,056 and in the production department is in the area of cleaning work with a value of 1,89. Based on the error producing conditions questionnaire (EPCs) for workers in the mining department the most common cause of error is poor equipment / instruments while for workers in the production department is a mismatch between the imagined risk and the actual risk. The recommendations given to companies are to improve work equipment, improve visual displays and provide an appropriate assessment checklist.

Abstract

The median nerve at the wrist becomes crushed in a condition known as carpal tunnel syndrome (CTS), which causes pain, numbness, and tingling in the worker's hand's palm. Risk elements for CTS include things like uncomfortable body posture at work, repetitive hand motions, and vibration exposure. Reviewing prior research on the connection between CTS and potential risk factors such worker hand posture, exposure to hand-arm vibrations, and repetitive hand movements is the goal of this study. The research approach involves searching for relevant articles using the terms carpal tunnel syndrome AND (occupational risk factors OR uncomfortable posture OR hand-arm vibrations OR repeated hand movements) in databases like ScienceDirect, PubMed, ResearchGate, and Scopus. The study indicates that Carpal Tunnel Syndrome is related to repetitive hand movements, hand-arm vibrations, and awkward hand posture during work. This research implies the importance of awareness about occupational safety. Additionally, the study suggests that job designs considering repetitive hand movements, vibrations, and incorrect posture can reduce the risk of Carpal Tunnel Syndrome. Therefore, it is hoped that organizations and workers can collaborate to create a safer, healthier, and more productive work environment.

Abstract

Peningkatan industri pupuk di dunia berimplikasi pada peningkatan jumlah industri amonia. Amonia memegang peranan penting pada proses produksi pupuk dalam hal penyediaan nitrogen. Proses pembuatan amonia melibatkan bahan baku berupa gas alam yang bersifat flammable dengan temperatur dan tekanan yang tinggi dalam setiap tahapan prosesnya. Primary reformer merupakan salah satu peralatan proses dalam produksi amonia dengan temperatur dan tekanan paling tinggi serta paling berisiko mengalami kegagalan yang dapat mengakibatkan terjadinya kebakaran/ledakan. Primary reformer berperan sebagai salah satu tahapan pemurnian gas alam dengan hasil berupa karbon monoksida. Identifikasi bahaya pada unit primary reformer dilakukan dengan menggunakan metode Fault Tree Analysis (FTA). Hasil analisis FTA menghasilkan bahwa sumber bahaya dari ledakan primary reformer dapat ditinjau dari faktor teknis dan faktor non teknis. Faktor non teknis menyumbang 74% dari penyebab terjadinya ledakan/kebakaran pada primary reformer. Hasil analisis risiko ledakan/kebakaran pada primary reformer dilakukan dengan menggunakan Dows Fire and Explosion Index dengan hasil radius area dampak adalah 51 meter. Nilai kerugian finansial mencapai US$ 23.640.285 dengan kerugian hari kerja minimal adalah 138 hari. Perangkat lunak Arial Location of Hazardous Atmospheres menghasilkan radius ledakan dengan dampak terkecil yaitu dapat memecahkan kaca jendela/pintu (0,5 psi) adalah 73 m dari primary reformer. Radius ledakan dengan kekuatan ledakan 1 psi (meruntuhkan rumah/perkantoran) adalah 48 m dari primary reformer.
