8287658 Feedback from wearing ‘heatstroke’ detection bracelets in a public works company

<h3>Objectives</h3> To prevent the risks associated with global warming, a public works company in the Paris region has been experimenting with the use of ‘heatstroke’ detection bracelets, which alert if body temperature rises by 1.5°C, thus preventing sometimes fatal accidents. Understand the experience of employees who use the bracelets, and advise the company on the benefits of these bracelets for workers on outdoor sites. <h3>Material and Methods</h3> Questionnaire submitted to testing employees on the progress of the experiment, initial knowledge of the risks and measures to adopt, alerts received, changes in practices, prospects for use and extension of the equipment. <h3>Results</h3> 24 respondents out of 29 volunteers informed by their direct supervisor of the experiment, the use of the equipment and the preventive measures to take. Bracelets worn consistently at first, forgotten after the holidays whereas weather was poor. Three age groups identified: &lt;35, 35-50, &gt;51 with equivalent distribution of pathologies and average Body Mass Index (NE 27.1). Occupations: pipefitter’s assistant, pipefitter, HGV driver, road repairman, welder, machine operator or mason. Two operators reported wrist discomfort, including a skin reaction. Alert triggered for 2 operators, one while working on the ground, the other while on vacation! Increased vigilance on the part of users, colleagues and managers, notably to hydrate before thirst sets in, despite a 2024 summer with no real heatwave. Everyone found the test useful, and wanted to wear the bracelet again, and suggest it to colleagues who had been exposed. <h3>Conclusion</h3> Our feedback illustrates a secondary benefit to the alert, reinforcing vigilance and the correct application of instructions. This equipment, which met with near-unanimous approval, could be tested in other sectors where work is carried out in a hot environment.
