... Workers with heat exposure have been associated with dyslipidemia, eye, and cardiovascular problems in several studies. Most of the work-related complaints were eye problems while working under high temperatures [58]. An increased odds ratio of dyslipidemia was observed in heat-exposed workers with high total cholesterol (OR=1.481, ...
... Eye problems, dyslipidemia, and cardiovascular strain have also been reported to be affected by heat exposure in other studies [58][59][60]. Regarding eye problems, the occurrence of thermal cataracts has long been well known as an occupational affliction. Conjunctival inflammation was significantly associated with workplace heat exposure among re-rolling mill workers in Bangladesh through a cross-sectional study (p<0.001). ...
... Conjunctival inflammation was significantly associated with workplace heat exposure among re-rolling mill workers in Bangladesh through a cross-sectional study (p<0.001). Infrared and ultraviolet rays emitted from the workplace environment may also cause many eye problems to heat-exposed workers [58]. Meanwhile, the specificity of a country in the development stage, such as Bangladesh, and a lack of awareness of personal protective equipment (PPE) should be considered for eye problems. ...
Objectives
Several studies on the health effects of heat exposure on workers have been reported; however, only few studies have summarized the overall and systematic health effects of heat exposure on workers. This study aims to review the scientific reports on the health status of workers exposed to high temperatures in the workplace.
Methods
We reviewed literature from databases such as PubMed and Google Scholar, using Preferred Reporting Items for Systematic reviews and Meta-Analyses (PRISMA) guidelines to identify studies that address health effects of heat exposure among workers.
Results
In total, 459 articles were identified, and finally, 47 articles were selected. Various health effects of heat exposure on workers have been reported, such as heat-related diseases, deaths, accidents or injuries, effects on the urinary system, reproductive system, and on the psychological system.
Conclusions
Our review suggests that many workers are vulnerable to heat exposure, and this has a health effect on workers.
... There are several methods that take into account factors such as noise, temperature, among others, in order to assess the conditions of the workplace (Asensio-Cuesta et al., 2012). Yasmin et al. (2013) established that it is important to have a surveillance system in the workplaces, by a proper inspection of the safety and maintenance of the industrial hygiene. ...
RESUMEN: En este trabajo se muestran las evaluaciones que se realizaron dentro de una empresa manufacturera electrónica ubicada al noroeste de México, con la finalidad de detectar las condiciones de riesgo tanto ambientales como las relacionadas con el diseño de la estación de trabajo, este estudio se centró principalmente en la iluminación en un área de la empresa que demanda esfuerzo visual por la naturaleza de las tareas allí realizadas. El análisis de posturas y levantamiento de cargas realizadas por los operadores se llevaron a cabo dentro de diferentes áreas en las instalaciones ya que, por decisiones de la empresa, se consideró mejor no tomar en cuenta la misma área en la que se evaluó la iluminación; a su vez se hizo uso del método NIOSH para comprobar la existencia riesgos potenciales para los operadores en la realización de tareas específicas. Como parte del presente trabajo, para cada situación riesgosa se presentan soluciones tentativas con el fin de que éstas sean tomadas en consideración por la empresa. Relevancia pata la Ergonomía: En este artículo, se ha podido confirmar la eficacia de la aplicación sistemática de un conjunto de herramientas y metodologías ergonómicas validados con el fin de proponer mejoras para una empresa dedicada a la manufactura de productos electrónicos. Es importante reconocer la eficacia de las herramientas mencionadas en la detección de factores de riesgo de alta prioridad, con el objetivo de mejorar el nivel de productividad en la empresa objeto de estudio, así como las condiciones de trabajo en que los operadores realizan sus tareas cotidianas relativas a las empresas industriales . Además, una propuesta de mejora se ha hecho en lo que se refiere de la media para el transporte de cargas mediante la incorporación de un nuevo dispositivo de transporte que fue especialmente adaptado a la actividad realizada, con la observación de una disminución significativa en el esfuerzo exigido por la tarea.
ABSTRACT: In this paper, assessments from an electronic manufacturer located in the northeast of Mexico are shown, aiming to detect the risk conditions regarding both environmental and workstation layout. This study is primarily focused in illumination conditions inside an area where high visual performance is needed due to the nature of the tasks required. Both, postural and lifting assessments performed by operators, were developed within different areas in the facilities, since the company considered more appropriate not taking into account the area where the illumination conditions were evaluated; additionally, the method NIOSH was used to confirm the existence of potential ergonomic risks for the operators in performing some specific job duties. As part of the present work, tentative solutions for each risk situation are presented, aiming to be taken into consideration by the company managers. Relevance to Ergonomics: By this article, it has been possible to confirm the effectiveness of the systematic application of a toolkit and validated ergonomic methodologies in order to propose improvements for an electronic manufacturer. It is important to recognize the effectiveness of the aforementioned tools in the detection of high priority risk factors, aiming to improve the productivity level in the company under study, and the work conditions where the operators perform their everyday tasks concerning the Mexican industrial companies. Additionally, an improvement proposal has been made in regards of the mean for transporting loads by incorporating of a novel transportation device which was specially adapted to the activity performed, observing a significant decrease in the effort demanded by the task.
Background:
Sunlight exposure is a major risk factor for eye disorders. Most outdoor workers cannot avoid sunlight exposure. This study aimed to analyze the relationship between outdoor sunlight exposure and eye disorders in an economically active population.
Methods:
This study analyzed the 2008-2012 Korea National Health and Nutritional Examination Survey data. Sunlight exposure was categorized as < 5 hours and > 5 hours. We also analyzed the dose-dependent relationship between exposure to sunlight and eye disorders (cataracts, pterygium, and age-related macular degeneration [AMD]) using data from 2010 to 2012 by subdividing the exposure groups into < 2 hours, 2-5 hours, and ≥ 5 hours. Eye disorders were diagnosed by an ophthalmologist. The study participants were stratified by sex, and the results were analyzed using the χ2 test and multiple logistic regression analysis.
Results:
In the female group, the odds ratio of pterygium in the high-level sunlight exposure group was 1.47 (95% confidence interval [CI]: 1.15-1.89). Regarding AMD, the odds ratios were 1.42 (95% CI: 1.16-1.73), 1.33 (95% CI: 1.03-1.73), and 1.58 (95% CI: 1.15-2.16) in the total, male, and female groups, respectively. Analysis of the dose-response relationship revealed that the odds ratios of pterygium in the high-level sunlight exposure subgroups of the total and female groups were 1.62 (95% CI: 1.25-2.08) and 2.00 (95% CI: 1.39-2.88), respectively.
Conclusions:
This study demonstrated a relationship between sunlight exposure and eye disorders in an economically active population. Women were found to be especially vulnerable to pterygium. However, additional prospective studies to clarify the pathophysiology of pterygium are needed.
