Full textAbstract:
Globally, the cement industry has been identified as a factor which causes significant pollution. This study is conducted to assess respiratory health effects of cement dust on the workers of Rabak cement factory, Sudan. This descriptive cross- sectional study was carried out at Rabak city. 134 samples were taken from the workers of the Rabak cement factory. The respiratory symptoms experienced, were scored and recorded using BMRC questionnaire on respiratory symptoms. The lung function measurements were performed using a portable Spirometer. The respiratory measurements of the subjects were Forced Vital Capacity (FVC), Forced Expiratory Volume in one second (FEV1) and Forced Expiratory Volume ratio (FEV1%). The results of the study showed that: the majority of the cement workers were infected by allergy. Cement dust might be the main cause of respiratory infection in exposed subjects. The duration of exposure to cement dust affects the prevalence of respiratory diseases among the cement workers. The present study clearly revealed that cement dust is not only the major cause of environmental pollution in the study area but also a threat to health of local inhabitants in addition to the worker. It has also been observed that majority of workers do not use personal protective equipment.

Introduction: Numerous studies have reported respiratory impairment by exposure to fine particulate matter (PM2.5). However, limited studies investigated its effects on fiber cement roof workers. Thus, our study evaluated the impact of PM2.5 on pulmonary impairments among workers and its risk factors. Design and Method: A total of 131 fiber cement roof workers have been chosen based on the inclusive criteria. Size-segregated particles were measured in the workplace of workers. Interview and spirometry tests were obtained to determine the respiratory impairments. Result: The results showed the mean concentrations of PM2.5 had exceeded the WHO and US-EPA standards. A quarter of workers had lung restriction, lung obstruction, and mixed. Workers are most likely to have shortness of breath and wheezing. A significant correlation was found between smoking, production workers, and a long work period with abnormal lung function. Fiber cement roof workers are significantly at risk of exposure to PM2.5. They are most likely to acquire abnormal lung function due to PM2.5 exposure. Conclusion: Our study recommended the industry constantly maintain its programs. The industry should keep using the wet process to prevent dust generation and water suppression from preventing dust spread, as well as to wear respiratory protection for workers to avoid PM2.5 exposure. We recommended as well to the industry to implement follow-up programs for workers with abnormal lung function. Further action is needed to protect the workers’ occupational health in the fiber cement roof industry.

The aim of this paper was to examine the manner in which Lafarge, a multinational cement corporation, has gone about executing an IT-based strategy. The analysis was motivated by multiple concepts of strategy. Based on currently authorized company framework. The study was done to, evaluate the development process of the ICT-based growth plan for Lafarge cement and to analyse the issues encountered by Lafarge cement in integrating information and communication technologies as a strategic plan. A standardized questionnaire was used to collect the results. Descriptive figures were used to validate the data's results. The full text discovered that the application of ICT techniques was split down into many levels with numerous sections being allocated to separate divisions and departments. The key players in the development activities were the management who adopted the technologies, external experts and IT workers. There were several planks in the development process, e.g. restricted jobs of method. Because of this, it was not as successful for the lower levels of workers that the ICT approach tackled. It is advised that senior management reduce the amount of administration in the company to move more effectively. There is a need for senior and middle level management to be properly qualified in managing policy execution, and how to effectively deal with different cultures in the enterprise.

In Ethiopia, occupation-related respiratory symptoms are extensively increasing with the expansion of cement manufacturing industries. However, little information is available on the extent of emissions and its association with chronic respiratory diseases. This study assessed the emission level of PM2.5 and its association with chronic respiratory symptoms among workers in Mugher Cement Factory, in 2018. A cross sectional study was employed on a total of 309 cement factory workers. Air check sampler, model 224-54, was used to measure the concentration of PM2.5. Variables with P value < 0.2 during bivariate analysis were selected as candidate for multiple logistic regressions. Significance level was set at P value <0.05. A total of 309 workers participated in the study with an overall response rate of 97%. The mean age of the respondents was 32.02 years (±4.7 SD). Emission levels of all PM2.5 samples were above the allowed standard. Among the workers, 50.8% had chronic respiratory symptoms and factors associated were: working in raw material receiving unit (adjusted odds ratio [AOR]= 7.5, 95% CI, 2.9, 19.4), cement milling unit (AOR = 2.4, 95 % CI ,1.2, 4.8), packing unit (AOR= 2.2, 95% CI= 1.1, 4.3), workers’ monthly income level below 3000 ETB (AOR; 5.8, 95% CI,1.9, 17.6), and workers’ regular medical checkup (AOR = 2.4, 95 % CI, 1.0, 5.2). The concentration level of PM2.5 and prevalence of chronic respiratory symptoms were high in the study area. Use of personal protective devices and periodic monitoring of installed pollution control devices is highly recommended.

The cement industry in the new research plant was established for ± 5 years. The existence of this establishment certainly has negative impacts, one of which is the production of high-intensity / noisy sound. The noise in the cement industry comes from the cement production process where raw materials are processed into finished materials that are ready to be distributed to consumers. The noise will certainly have an impact on the surrounding workers. This study aims to show the very poor intensity of the processes that occur and to see the relationships that occur in communication, psychology, and worker physiology. The highest noise occurs in the raw factory area with a distance of 5 meters from the equipment where the intensity is 93.23 dB. Based on the Regulation of the Minister of Manpower of the Republic of Indonesia No. 5 of 2018, this exceeds the allowable threshold value of 85 dB with an exposure time of 8 hours. And responsive from workers who do not feel disturbed by what happened.

Background: Construction industry chiefly depends on the cement. The constituents in the cement have various health effects in the exposed group. The present study focused to realize the health effects of cement exposure and duration of exposure.Methods: The sample size was 831 male workers. The labourers included were construction workers (masons, helpers and concrete mixers) and cement loading and unloading workers. They were categorized in to five groups which were 5-9, 10-14, 15-19, 20-24 and 25+ years based on the duration of exposure to cement. Health hazards among these labourers were categorized in to lung function impairment symptoms, cutaneous symptoms and other symptoms.Results: High frequency of respiratory tract ailments (persistent cough 54%, breathlessness 47%) was observed among loading workers as they were handling cement dust. Burning was the most observed one in concrete mixer (70%), hair loss and change in hair colour was observed in 60% of all categories of workers. Skin related ailments were more prevalent among masons, helpers and concrete mixers.Conclusions: The frequency symptoms had correlation with their nature of work in the construction industry. Prolonged exposure to hazardous substances will decline the efficiency of labourers by malfunctioning their physiological functions. Proper awareness about the hazardous substances and well taken precautions among these labours can enhance their efficacy and wellbeing.

Background: It is unfortunate enough that cement industry workers despite of so many awareness campaigns, unable to seek protection against dust of cement and thus bound to face respiratory problems. In developing countries no legitimate bindings regarding protection of such workers though cement industry is one of the largest industries. Methods: Non probability sampling done in which cases taken from cement workers and control taken from nearby residents matched for age gender and smoking status of participants. Results: When studied for the restrictive and obstructive respiratory problems it was found 2.82 times and 4.71 times higher in cases respectively. When cases studied for duration of working against disease developed, it was found that 61.81% developed obstructive pulmonary disorder and proportion increased from 23.63% to 30.80 as the work span increased from 0-5 years to 5-15 years respectively. When it has been observed for restrictive pulmonary disorder, it has been increased from 3.6% to 5.4%. Conclusions: It has been observed that workers have either obstructive pulmonary dysfunction or normal pulmonary functions and on increasing the duration, number of workers with restrictive pulmonary function increases proportionately.

In the last years we have to think about the question of emission reduction. One of the biggest producer of these emission is industry, where the cement industry comes under it. The effort of cement-workers and other manufacturers of building materials is the reduction of harmful oxides in our air, including CO2, which is one of a group of unfavourable oxides.This paper deals with the study possibility of partial compensation limestone by FBC-ash. The expected effect is the reduction of CO2 emissions and saving limestone. Following the previous stage of the research a recipes were designed for Portland clinker burning limestone-based and FBC ash, it was carried out laboratory burning and on produced cements were made basic technological tests.

Objective: The challenge of this work was to diagnose the sustainable benefits of civil construction and the perception of employees in a cement factory based on a new production methodology.
Method: The study was carried out through quantitative and cross-sectional research, with the application of a questionnaire via Google forms for employees and customers of the factory under study.
Results and conclusions: The sampling plan was 62.79% male, 58.14% married, 28.93% aged between 28 and 32 years old, 32% technical level, 11.63% post graduates and 22% of participants demonstrated understanding about sustainability. 77% of employees are unaware that the industry used a less aggressive production method for the environment, unique in Maranhão. We conclude that the industry under analysis has sought to implement good socio-environmental practices, but to achieve more expressive results, it needs to qualify and involve the entire production and consumption chain of the civil construction market with qualification programs, to guarantee the horizontalization of information with effective socio-environmental actions and thus preserving future generations.
Research implications: The research highlights the perception of workers/collaborators in the cement industry on the consumption and sale of products that minimize the negative effects on the environment.
Value of originality: This is original research that contributes to the understanding of the impact of the cement industry, during the production process, from the extraction of raw material. Since it degrades the environment by contaminating water and soil, it also interferes with human health, in addition to proposing the search to balance the negative socio-environmental impacts through cement production.

Background: The health risks was reported in the cement industry in various study conducted in different settings. This study aimed to assess the occupational health risks among cement factory workers of Dang district of Nepal. Methods: A cross-sectional study in 212 workers was conducted in Samrat Cement Company and Sonapur Minerals and Oils of Dang district in between July, 2019 to January 2020 using structured questionnaire. Proportionate stratified random sampling was used for participant selection. The collected information was entered in Statistical Package for Social Sciences (SPSS). Descriptive and inferential statistical analysis was performed. Results: Of 212 workers, the respiratory and musculoskeletal health risks were reported by 13.2% and 22.2% of factory workers, respectively. About 29.2% were smokers. Two-third (66%) had poor knowledge of Occupational Health and Safety related questions and 17.9% had poor practice to prevent respiratory problems. Smokers (p=0.004) and access to safety measures (p=0.008) were significantly associated with respiratory problems. Educational status (p=0.021), work shift (p=0.022) and first aid availability (p=0.009) were statistically significant with musculoskeletal health risk. Conclusion: Low occupational health risk and low knowledge was reported by cement factory workers. Special protection to workers above 40 years and declaring the cement factory as smoking restricted area could minimize respiratory risk. Access to and condition of safety devices need to be monitored by factory administration. Behavior change communication and safety orientation could help the workers use safety devices. Key words: Occupational health risk, respiratory health risk, musculoskeletal health risk, knowledge, practice, cement factory workers.

Background: Cement manufacturing is among the growing industry in Tanzania. It involves processes from blending, kiln burning, clinker, grinding and cement final production. All of these cement manufacturing processes generates cement dust which contain silica and other toxic materials which can potentially affect respiratory system of exposed workers. Methods: This cross sectional comparative study design was conducted at cement processing factory and Ndanda mineral water processing factory as control, all of these factories are located in Mtwara region in Tanzania. A total of 398 workers were selected randomly from these two factories. Data were collected using structured questionnaires for respiratory health symptoms, Checklists was used for the observational parameters. Dust sampling was done using Side Kick Casella (SKC) pumps and PVC filter on IOM cassettes was used to determine dust exposures. The analysis was done by SPSS program vers 20. The significant association between the dependent variable and the factors was registered when Pvalue was less the 0.05. Results: Packing and cleaner were the sections with higher total cement dust concentrations above Occupational Exposure Limit which were 33.24 and 15.39 mg/m3 respectively. Workers in cement processing factory were exposed to higher levels of total dust with AM 14.1033 mg/m3 (SD 4.357) than in mineral water processing factory AM 0.0867 mg/m3 (SD 0.035). The Prevalence of respiratory symptoms was higher among workers in cement processing factory (45.7%) than in mineral water processing factory (25%), this was statistically significant. Conclusion: Exposure to cement dust in a working environment causes the increase in work related respiratory symptoms and reduced lung function. A control measure to decrease the dust exposure level among cement workers in line with periodic medical examination is highly needed.

Background: A higher incidence of occupational diseases has been reported recently compared to the past years. One of the industries where workers are remarkably exposed to dust is cement industry. Several studies have been conducted to evaluate pulmonary functions and biochemical parameters of workers exposed to cement dust in factories and construction sites, but few were concentrated among loading and unloading workers of warehouses. Hence the present study was undertaken to find out the effect of cement dust among loading and unloading workers of cement warehouses.Methods: This study was conducted among 82 exposed (cement dust) and 82 non-exposed individuals. Frequency of symptoms, biochemical parameters and spirometric values were taken from all subjects. Spirometric parameters recorded were, forced vital capacity (FVC), Forced expiratory volume (FEV1), FEV1/FVC% and Peak expiratory flow rate (PEFR).Results: Out of exposed group, 51.2% had cough, 46.3% had rhinitis 45.2% had breathlessness. FEV1 and FVC showed significant reduction while FEV1/FVC values were normal. No significant changes were seen in renal function tests or liver function tests. Mean value of erythrocyte sedimentation rate (ESR) was found to be significantly increased.Conclusions: Compared to normal healthy adults the loading and unloading workers in cement warehouses showed restrictive lung disease and an increase in ESR representing a non-specific inflammatory change. A continuous bio monitoring of health status must be initiated for these employees and awareness campaigns regarding the exposure and use of standardized protective devices must be mandated.

Abstract. The cement industry is the largest manufacturing industry, vital for sustainable development, and very risky for workers to be exposed to dust in various processes, including production. Continuous exposure to dust can cause pulmonary function disorders. This study aimed to analyze the relationship between dust exposure, age, length of work, working period, use of PPE (masks), smoking habits, and pulmonary function disorders in labor. This research used an observational method with a cross-sectional approach. The research sample was a total population of 38 male workers at Semen X company, engaged in the cement bagging industry as business activities. Data collection was by interviewing respondents, measuring the level of inhaled dust with a personal dust sampler, and checking the lung capacity with a spirometer. Data analysis was performed bivariate with the chi-square test. The results showed that there was a relationship between the use of PPE (mask) (p = 0.006) with pulmonary function disorders.

Background: Pollutants exerted from different industries are hazardous for both employees and the environment. Though cement industry is playing a key role in economic growth but is a major source of air pollution. Its exposure affects pulmonary functions due to alteration of structural and functional properties of lung. Peak Expiratory Flow Rate (PEFR) is a simple, less expensive pulmonary function test which can be done by spirometer to detect obstructive changes in the respiratory tract.This study is aimed to assess the effect of cement dust on peak expiratory flow rate of workers, those who are exposed to cement dust directly in cement factory.
Materials and methods: This case control study was conducted in the Department of Physiology, Chittagong Medical College, Chattogram in collaboration with Heidelberg Cement Bangladesh Ltd at Chattogram from January 2018 to December 2018. Total 88 male workers with age ranged from 20 to 45 years were included in this study by consecutive sampling method. Case group workers were selected from those who were working at least two years in direct contact of cement dust and control group were from office workers of same factory those who were not in direct contact of cement. 44 subjects were included in each group. A predesigned data collection form was filled up by the researcher,which contained information regarding general physical status, job history, present and past disease, drug history of workers. Individual’s height, weight was measured and BMI was calculated. PEFR was assessed by a portable digital spirometer (Chestgraph HI-101, Japan) in upright sitting posture. After compiling data,statistical analyses were done by using SPSS version Windows 25. Unpaired student's 't' test was done for statistical analysis.
Results: PEFR of Control and Case group was 7.84±2.21 L/sec and 5.73±1.79 L/sec respectively. In this study Case group showed significant reduction of PEFR (p<0.001) compared to Control group workers.
Conclusion: This study result concluded that occupational exposure to cement dust has deleterious effect on lung which is evident by reduced Peak Expiratory Flow Rate (PEFR) of cement exposed workers.

AbstractTitle: The Relationship between Noise Exposure with Blood Pressure and Pulse of Workers in a Cement Packaging IndustryBackground: Noise pollution is the distrubing or excessive noise that may annoying, distracting or even harmfull to the people who hear it. Noise pollution can induces alteration of various physiological responses, especially on the cardiovascular system, in people exposed to it. The aim of the study was to analyze the relationship between noise exposure with blood pressure and pulse of workers in cement packaging industry. Methods: A cross sectional study design was employed in 2016 at cement packaging industry in Tuban, Indonesia. Sample size were 22 workers obtained by using simple random sampling technique. Noise level was measured at production unit with a calibrated Sound Level Meter. Workers characteristics were gathered with an appropriate questionnaire. Blood pressure and pulse were measured cross shift (before and after noise exposure) using digital tensimeter. For analyzing data, paired t-test and pearson correlation test were used. P < 0.050 was considered statistically significant.Results: Noise level at all production areas were exceed the TLV, over 85 dBA. Most workers were 42 years old, had over 15 years of worked periode and 77.3% of respondents were using EPE with ear plug type. Either sistolic and diastolic blood pressure before noise exposure were normal, but after that, they were prehypertension. Mean pulse of workers before and after noise exposure were 76,64 x/second and 86,91 x/second.Conclusion: There were significant differences between the systolic blood pressure, diastolic and pulse before and after work. Meanwhile, there were significant associations between noise with raised systolic blood pressure, diastolic blood pressure and pulse on workers of cement packaging industry. So, preventive of noise should be controled by using convenient EPE for workers.

Keberadaan industri semen di Kecamatan Bayah seperti dua sisi mata uang logam, memiliki dampak positif dan negatif tertentu bagi masyarakat sekitar, khususnya terhadap mata pencaharian nelayan Bayah. Penelitian ini bertujuan untuk mendeskripsikan kondisi mata pencaharian nelayan sebelum dan sesudah adanya industri semen, dan mengidentifikasi strategi adaptasi untuk menjamin keberlanjutan mata pencaharian di kalangan nelayan. Metode yang digunakan yaitu deskriptif kualitatif dengan nelayan sebagai key informan. Data didapatkan melalui kuesioner, wawancara mendalam, Focus Group Discussion (FGD), dan observasi lapangan. Hasil penelitian menunjukkan bahwa masuknya industri semen (PT. Cemindo Gemilang) di Kecamatan Bayah membawa perubahan berantai, baik dari perubahan ekologis maupun kehidupan sosial ekonomi nelayan. Perubahan ekologis menyebabkan bergesernya daerah tangkapan ikan, perubahan ketersediaan produk perikanan sebagai modal utama, peningkatan biaya dalam mengakses sumber daya, dan berimplikasi pada pendapatan rumah tangga nelayan. Ketidakpastian penghasilan seringkali ditanggulangi dengan diversifikasi mata pencaharian, yang merupakan salah satu bentuk strategi nafkah ganda yang sudah dilakukan oleh nelayan Bayah sebelum adanya industri semen. Namun setelah adanya industri semen membuka peluang untuk bekerja di sektor non perikanan yaitu sebagai buruh pabrik dan kuli panggul di dermaga. Strategi adaptasi untuk menjamin keberlanjutan mata pencaharian dilakukan melalui adaptasi berupa penganekaragaman sumber pendapatan, penganekaragaman alat tangkap, perubahan daerah tangkapan, dan memanfaatkan hubungan sosial. Title: The Impact of the Cement Industry to the Livelihood System of Bayah Fishers The existence of cement industry in Bayah Sub-district is like two sides of the same coin, it has a positive and negative impacts for the surrounding community, especially on the livelihood of Bayah fishers. This study aims to describe the livelihood conditions of fishers before and after the cement industry exists in their village as well as to identify adaptation strategies to ensure the sustainability of fishers livelihoods. The study used descriptive qualitative method involving fishers as the key informant. Data were collected through questionnaires, in-depth interviews, FGD, and field observations. Results showed that the existence of cement industry (PT. Cemindo Gemilang) in Bayah Sub-district brought about a series of change toward ecological and socio-economic life of the fishers. Ecological change led to shifting of catchment areas, changes in the availability of fisheries product as their major capital, increased costs of access to resources, and implications toward household incomes. Uncertainty of income was frequently solved by varying livelihoods, and it was one of strategies that has been implemented by Bayah fishers even before the cement industry exists. However, the existence of cement industry has created job opportunity in non-fishery sector such as factory workers and dock porters. Adaptation strategies to ensure the sustainability of their livelihood are: diversification of sources of income, diversification of fishing gear, relocation of fishing area and empowerment of social relationship.

Full textAbstract:
The cement industry is one of the main world industries with exposure to a wide range of hazardous chemical and physical occupational agents that may increase free radicals and lead to disease. The aim of this study was to evaluate oxidative stress, biochemical markers, and psychological parameters among cement plant workers. In this cross-sectional study, 40 workers exposed to cement and 40 office employees were selected as the exposed and non-exposed groups, respectively. Exposure to cement dust, silica, and noise were, respectively, assessed using the NIOSH 0600, NIOSH 7601, and noise dosimetry methods. Oxidative stress biomarkers including malondialdehyde (MDA), superoxide dismutase (SOD), catalase (CAT), total antioxidant capacity (TAC), and biochemical parameters were measured in the serum of all participants. Depression, anxiety, and stress were assessed by the Depression Anxiety Stress Scales (DASS-21) questionnaire. The results demonstrated that the level of MDA as a marker of oxidative stress was significantly higher in the exposed group. The level of antioxidant enzymes including SOD and CAT were also significantly higher in the exposed group. The level of TAC was lower in the exposed group, but the difference was not statistically significant. The levels of alkaline phosphatase (ALP), aspartate transaminase (AST), and the scores of depression and stress were also significantly higher in the exposed group. According to our results, noise, cement dust, and silica exposure were associated with oxidative stress, and this may be one of the mechanisms in which they adversely affect liver function and mental health.

Full textAbstract:
The cement industry is considered as a major pollution problem because of dust and particulate matter emitted at various steps of cement production. In the present study, volunteer male workers from a cement factory were studied for oxidative and nitrosative stress biomarkers in relation to their serum levels of aluminum (Al) and chromium (Cr). The subjects were divided into two groups of direct and indirect exposure. Subject who worked in production steps were considered as direct exposure group, and those who worked in administration building were considered as indirect exposure group. For comparison, healthy subjects at the same age and socioeconomic status were tested as a control group. Serum levels of lipid peroxidation (LP), total antioxidant capacity (TAC), total thiol molecules (TTM), and nitric oxide (NO) as well as Al and Cr were measured. The results indicated a significant increase in Al ( P = 0.001) and Cr ( P = 0.009) levels in direct-exposed workers in comparison to healthy control group. Further, a significant increase in Al ( P = 0.002) and Cr ( P = 0.009) levels was observed in direct-exposed workers as compared to indirect-exposed one. Serum levels of TTM and TAC were significantly lower in both direct- and indirect-exposed groups in comparison to healthy control group ( P = 0.00). Serum TTM and TAC were significantly lower in direct-exposed workers as compared to indirect-exposed ones ( P = 0.00 and P = 0.024, respectively). There was no significant difference on the level of LP and NO among groups. A correlation was found between serum level of Cr, TAC, and platelets between direct- and indirect-exposed groups ( P < 0.05). Further correlation was found among serum level of Cr and those of TTM, platelets, and chronic disease ( P < 0.05). Chronic disease had a significant influence adjusted to other predictor variables on the post-shift values of Al ( P < 0.05). Although plasma levels of Al and Cr were found in normal ranges, analyses confirm their role in impairment of TMM and TAC.

AIM: The aim of this systematic review was to investigate heavy metal roles at skin disease of humans in the cement industrial area.
METHODS: All research reporting a specific heavy metal, which could be increasing the risk of the disease, cause cement induced to skin. Fourteen selected articles from our inclusion criteria rated using eight quality-appraisal criteria derived from Strengthening the Reporting of Observational Studies in Epidemiology checklist and following preferred reporting items for systematic reviews and meta-analyses methodology.
RESULTS: We performed a systematic review of published articles between 2009 and 2019 from ten case–control, two cohort, one ecological study, and one cross-sectional study showed the heterogeneity of the study design. The studies are focusing on the relationship between heavy metal and skin disease that appeared in cement plant areas such as dermatitis, skin cancer, eczema, and other allergies. Chromium, nickel, cobalt, zinc, cadmium, mercury may present and play an important role for human skin disease.
CONCLUSION: Heavy metals have been found in the skin of human living and work around the cement industry. Chromium, cobalt, and nickel are almost certainly present in every case of dermatitis and eczema. Signs and mild symptoms of skin disease include redness, itching, starch, and dryness. Elements such as cadmium, lead, and mercury usually are found in chronic skin disease (psoriasis and skin cancer) on a biologic test. These findings should raise an important concern and recommendation policy for controlling raw materials contains heavy metal in cement industrial areas and proper protection for workers and non-worker.

Abstract: Industry players are encouraged to automate as a result of technological advancements. However, due to lack of finances several businesses continue to require human labor in the production process, particularly in the operation of transferring items . Transportation activities at Dock 16 Ilir in Palembang City, starts with delivering items from the shop to the ship or vice versa by utilizing human strength in less ergonomic work positions with little consideration for the weight of the load. Whencarrying goods , the body is bent, the neck is bent, and the arms are distant from the body, putting the body at a very high risk of injury. This type of working position causes muscle aches ranging from mild to severe. The personnel seen in this investigation were rice transporters and cement transporters. The aim of this study is to quantify the workload and provide a design tool to help lessen worker concerns. The Nordic Body Map, Rapid Upper Limb Assessment (RULA), and Ovako Working Analysis System (OWAS)methodologies were used in this investigation. The study's findings showed that the five cement transport workers and four rice transport workers were at risk of developing muscoskeletal illnesses, with a risk level of 3 to 4, indicating that the risk category is very high and comprehensive treatment is required as soon as feasible. According to the OWAS technique, the posture of rice transportation employees has a value of 3, indicating that they are at high danger. Meanwhile, the working posture of cement transportation has a score of 7 with a risk level of 4, indicating that the danger of MSDS is very high. The developing aids are projected to lower the danger of Muscoskeletal Disorders in a backpack-like style that can resist large loads and reduce the risk of Muscoskeletal Disorders.

Full textAbstract:
The co-processing of different wastes as fuels in the manufacture of cement clinker not only meets the objectives of a circular economy but also contributes to the reduction in CO2 emissions in the manufacture of Portland cement. However, waste used as alternative fuels, such as sludge or organic-rich residues, may contain naturally occurring radionuclides that can be concentrated during the combustion process. In this study, the presence of natural radionuclides (radioactive series of uranium, thorium, and 40K) and anthropogenic radionuclides (137Cs) in these wastes has been investigated by gamma spectrometry. Possible relationships between the radioactive content and the obtained chemical composition, determined by X-ray fluorescence, have also been studied by applying a principal component analysis (PCA). The results showed that the wastes with the highest radioactive content were sewage sludge with activity concentrations of 238U and 210Pb of 321 ± 38 Bq kg−1 and 110 ± 14 Bq kg−1, respectively. A correlation between radioactive content and Fe2O3 concentration was also observed. The annual effective dose rates to workers for the ashes estimated from the ash content ranged from 0.0033 mSv to 0.092 mSv and therefore do not pose a risk to workers as they are lower than the 1 mSv per year limit for the general public (DIRECTIVE 2013/59/EURATOM).

ObjectiveExposure to asbestos is the major cause for malignant pleural mesothelioma (MPM), but the causal link of individual cases is difficult to establish for lack of exposure information and long disease latency.MethodsWe established a retrospective cohort of workers employed in asbestos industries during the period of 1950–1989 and the occurrence of MPM during the period of 1980–2009 was examined with the Taiwan Cancer Registry. Estimated rate ratios (eRRs) were computed for each factory where any case of MPM was diagnosed by assuming Poisson distribution with a minimal latency of 20 years.ResultsA total of 18 MPM (17 males, 1 female) in eight factories were found. The incidence rate of MPM for the eight factories was 18.0 per million, ranging from 6.2 per million (military factory) to 268.2 per million (asbestos cement). We observed significantly increased risks for MPM in asbestos cement, thermal insulation and shipbuilding industries, with eRR (genders combined) of 113.6, 87.5 and 15.8, respectively. The sensitivity analyses considering latency showed similar findings in latency≥30 years, and the shipbuilding industry presented a significant eRR given a latency≥40 years. The gender-specific eRR showed similar results in men, but high eRR of 729.6 was observed in an asbestos cement factory where a female MPM was diagnosed.ConclusionsThis nationwide study in Taiwan comprehensively shows that different asbestos manufacturing processes, including asbestos cement, thermal insulation and shipbuilding industries, were at significantly increased risks for MPM. We recommend to establish a medical screening programme for workers previously exposed to asbestos to identify MPM and other asbestos-related diseases at an earlier stage.

Cement industry caused environmental impacts at all stages of the process in the area; include emissions of airborne pollution in the form of dust, gases, noise and vibration. This study is conducted to evaluate the noise pollution and heat stress in different parts of Rabak Cement Factory. The study involved the exposed and unexposed groups. The noise levels were measured by the aid of an occupational health specialist who was familiar with the measuring device instructions and the study protocol. On the other hand, structured questionnaires were used to assess the workers' response to noise pollution in all sections of the factory. Environmental temperature was measured as close as feasible to the work area where the workers are exposed. The measurements were taken from two locations in the factory; the chemical laboratory and kiln in order to determine the heat stress. Some instruments were used to calculating heat stress parameters. Highest noise level was found in compressors 105.33 dB, conveyor belts 101.66 dB, raw materials mills 98.33dB and workshops 97.00 dB. The levels exceeded the maximum permitted noise level described by WHO. There is high temperature in work environment over standard level which may lead to heat stress. For these findings, the company should create a formal noise and heat stress management program.

Introduction: Exposure to any type of noise has a potential risk. Higher the level of noise and longer duration of exposure, the more the risk for the hearing sensitivity and health as a whole. The objective of the study is to determine the prevalence of Occupational Noise Induced Hearing Loss (ONIHL) among the industrial workers in Bhutan and to ascertain high risk establishment and vulnerable occupations. Methods: The hearing assessment was conducted among 1638 workers considering different types of industries and occupations to ascertain the prevalence of occupational noise induced hearing loss and vulnerable group amongdifferent industries and occupations. Descriptive statistics and binary logistic regression were performed to test the significance of ONIHL among the various independent variables. Results: The study found that the prevalence of ONIHL stands at 27.9% among industrial workers in Bhutan. 42.45% of candidates who had ONIHL reported with tinnitus in either or both ears. This study founda significant association between the exposure duration and the severity of ONIHL among the industrial workers. Considering the type of industry, wood based industry, hydro services, cement and polymer were found to have a higher prevalence of ONIHL and similarly, higher prevalence of ONIHL were found among occupations such as blaster, chipper, carpenters, dryer (knife grinder) and crusher operators. Conclusions: This study conduces that prevalence of ONIHL among industrial workers is found to be at the higher side and some of the occupations and industries impose higher risk. The study suggests that there is need for intervention such as strict enforcement of the permissible exposure limit, monitor and evaluate hearing conservation programs, and providing advice and recommendation to address such issues by the relevant agencies and industries

Introduction. Building materials industry, including the production of clay and ceramic building bricks, cement, concrete products, saw building stone, sawn wood, granite blocks and rubble, is one of the most important economy units, prompting authors to generalize research data about working conditions and the incidence of occupational diseases in the main production building materials industry/ The data were accumulated during many years. Material and methods. Research methods included a comprehensive study of the working conditions of employees at enterprises of construction materials industry, followed by in-depth periodic medical examination. Then, with statistical methods (determination of the confidence interval index of the binomial distribution) calculated confidence interval for the prevalence of patients with an established diagnosis of occupational diseases in similar enterprises. Results. Results of 40-years research on occupational hazards parameters and physical examination of workers employed at productions of clay and ceramic bricks, cement, armed concrete, saw building stone, lumber wood, granite blocks crush stone were summarized because of the absence of complex estimation of work-place conditions and incidence of occupational diseases in main production of building materials industry. Typical occupational hazards were established for the every production. Many productions show the greatest disadvantage concerning levels of physical overload that was neglected by specialists in occupational health and safety for many years. The prevalence of patients suffering from chronic occupational diseases was predicted for employees of investigated productions and the most relevant forms of occupational pathology were determined. About 7.7% of workers in investigated productions appeared to suffer from occupational diseases that were not timely diagnosed. This figure is approximately 10 times higher than official statistics. The dependence of the prevalence of patients with occupational diseases from the level of technological modernization of production was revealed. If we can accept the proportion of patients with occupational diseases among employees working in the complex automated production (the highest degree of organization of labor) for referent unit than at the enterprises with the other technologies the proportion will be different: automated production - 10, mechanical work - 4, mechanical hand work - 5, hand work - 3.

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.

Coal mining is vulnerable to multiple kinds of threat from water incursion. Many coal seams contain dissolved H2S, which may be released during mining, seriously endangering the health of workers. Orthogonal testing was used to analyze the physical and mechanical properties of composite slurries in different proportions. The results showed slurry with a water-solid ratio of 0.8:1 to have the optimal combination of properties. A uniform experimental method was used to investigate the impact of the water-cement ratio, concentration of sodium silicate, and volume of cement-sodium silicate (CS) on the setting time and consolidating strength of CS slurry. This paper provides the appropriate application scope of two grouting materials (optimized composite slurry and CS slurry), based on experimental data and the results of a large number of in situ trials. Finally, the optimized composite slurry and cement-sodium silicate slurry were used to carry out grouting of the center auxiliary transport roadway of the 3−1 coal seam at the Ningtiaota Coal Mine, operated by the Shaanxi Coal Industry Group. It was shown that the type and formula of the slurry could be changed in a timely manner, based on the water outlet and concentration of H2S at the site, achieving successful grouting reinforcement and seepage-proofing.

Introduction Workers in the construction industry frequently work in construction sites with numerous areas that can potentially accumulate water, such as tanks, wet cement surfaces, or water puddles. These water collection sites become ideal breeding grounds for mosquito infestation, which leads to a higher prevalence of mosquito-borne diseases, especially malaria and dengue among construction workers. Despite that numerous factors have been identified in controlling vector-borne diseases, the specific factors that influence mosquito control at construction sites have yet to be explored. Aims This systematic review aims to determine the factors associated with mosquito control among construction workers. Methods Primarily, articles related to factors associated with mosquito control among construction workers were collected from two different online databases (ScienceDirect and EBSCOhost). Two independent reviewers were assigned to screen the titles and abstracts of the collected data, stored in Microsoft Excel, against the inclusion and exclusion criteria. Afterwards, the quality of the included articles was critically assessed using the Mixed Method Appraisal Tool (MMAT). Of the 171 articles identified, 4 were included in the final review. Results Based on the thorough evaluation, mosquito-related knowledge, practical mosquito prevention measures, and Larval Source Management (LSM) were identified as vital factors associated with mosquito control among construction workers. The significant association between mosquito-related knowledge and control practices indicates higher knowledge linked to effective practices, particularly among female workers and those who were recently infected with malaria. Concurrently, there were notable challenges regarding sustainable preventive measures and larval control methods in construction settings. Conclusion Implementing effective mosquito control, including knowledge and practice on mosquito control together with vector control, is highly required to suppress the expanding mosquito population. It is recommended that employers provide continuous mosquito control education and training to their employees and reward them with incentives, while employees should comply with the guidelines set by their employers to ensure successful mosquito control and reduce the spread of mosquito-borne diseases in the construction industry.

Background: In this era of globalization one of the growing industries is the construction industry and there are various occupational problems faced by the workers especially in Asian countries mostly in India; the problems are related to both physical and mental health. All the construction sites generate high concentration of dust particles from cement, silica, asbestos, concrete, wood, stand and stand that causes respiratory problems in the workers. PEFR is the maximum air that is generated after forceful expiration, after full lung inspiration. So if there is any accumulation of dust particles the PEFR decreases as the elasticity of lungs to recoil is distrusted due to the lodged particles. Material and Method: A descriptive observation study was carried out on 50 building construction workers. The purpose of the study was explained and informed consent was taken. The PEFR was measured using peak expiratory flow meter. The data was analyzed using standard statistical software. Result: The procedure of using peak flow meter that was carried out for 3 times and the highest value from the three was considered as peak flow rate, using statistical method mean and standard deviation were calculated. The mean of Peak Expiratory Flow Rate is 321.1 L/min. Conclusion: This study concluded that the peak expiratory flow rate is reduced in building construction workers those who are working for than 2 years on the construction sites. Key words: construction workers, occupation diseases, PEFR, peak expiratory flow meter.

Respirable dust, including respirable crystalline silica (RCS), is a common risk to health for construction workers. New Zealand and international literature has shown that construction workers are likely exposed to high levels of dust in the performance of their work. However, very little is known about the prevalence of controls used to minimise the dust exposure. An on-site survey of 250 construction workers was undertaken in Hamilton, New Zealand. Respondents were asked how frequently they completed any of six common high-risk activities for dust exposure: [1] cutting or drilling concrete, [2] grinding or polishing concrete, [3] jackhammering, [4] crushing concrete, [5] cutting or sanding wood, [6] cutting or sanding plasterboard or fibre cement board. For each activity completed more than once a month, workers were asked about the controls they used to minimise exposure to dust and their consideration of the risks to their health. Low levels of controls were reported across the high-risk activities. The majority of workers did not usually use water suppression when jackhammering (79.6%) or crushing concrete (56.3%). Nearly two thirds (62.8%) of workers did not use dry dust extraction when cutting or sanding wood, and over a quarter of respondents used neither water suppression nor dry dust extraction when cutting/drilling concrete (30.1%) or grinding/polishing concrete (25.0%). Half of the workers (50%) often or always wore respirators when performing dusty work but fewer than half of ever-wearers were fit-tested or clean-shaven. Younger workers (<25 years) were significantly less likely to consider risks to their health or wear a respirator compared to older workers (≥25). This study provides an insight into the use of dust controls in the construction industry in New Zealand. Future work should investigate how to encourage or enable uptake of stronger dust controls.
