“…The human body maintains its temperature at approximately 37 • C through several types of heat transfer, like sweat and vascular expansion [34][35][36], seeking to keep itself in a thermally comfortable situation in relation to its environment [37]. During the execution of exercises, the blood flow to the muscles used undergoes vasoconstriction and it is observed that there is an increase in skin temperature in the muscle region used during the activity performed [38,39] and that will remain during the execution of the exercise; there is also a vasodilatory response in order to facilitate heat loss through the skin, which will lead to a reduction in body temperature [34,35,39] in order to keep body temperature within acceptable limits.…”

Risk analysis is one of the main tools for preventing the occurrence of Work-Related Musculoskeletal Disorders. New methods of risk analysis should seek to be more agile and simplified, encouraging them to be widely applied in work environments. This paper aimed to develop a rapid tool for assessing the risk of developing Work-Related Musculoskeletal Disorders (WMSDs) arising from repetitive actions of the upper limbs, while using a thermographic camera to measure skin temperature variation. A workstation was developed in an environmentally controlled laboratory, representing the five levels of risk presented by the Occupational Repetitive Actions Index (OCRA) Index, which were performed by 32 participants for 20 min. each level. There was a significant change in forearm skin temperature at all risk levels (p < 0.001), with a positive linear correlation (r = 0.658 and p < 0.001), which led the authors to perform linear regression analysis for the forearm region. The Predicted OCRA Index calculation equation was successfully developed (R = 0.767 and R² = 0.588), while using as independent variables: air temperature and temperature variation of the forearm skin. The Predicted OCRA Index can be applied as a screening tool for large numbers of workers in the same company or sector, due to its speed of application and the determination of risk level, but it does not replace the original OCRA Index.

BACKGROUND: This article presents the results of an investigation into the thermal aspect of workplaces of the metallurgical branch of furniture manufacturing, looking for the number of dissatisfied people in the environment. OBJECTIVES: This study aims to analyze the thermal suitability of a metallurgical industrial environment, from four interpretations of vote ± 1 (slightly warm or slightly cool) on the thermal sensation range, reported by workers. METHODS: The methodological approach consists of quantitative research and a literature review set for this work, composed of spreadsheets and statistical processing of data. Data collection took place through the use of environmental variables measurement equipment and software for statistical assistance. RESULTS:The results indicate an average above 35% of workers dissatisfied with the environment, thus, portraying the lack of suitability. CONCLUSIONS: It was noted, further, that, although average temperatures may be between 21 • C to 28 • C, workplace improvements can be made, so that the thermal sensations will be satisfactory.
