Abstract

L'invention concerne un système de gestion de la sécurité d'un lieu de travail toxique/dangereux. Ce système comprend : un capteur de gaz placé dans le lieu de travail pourvu d'un espace clos pour détecter la température, l'humidité, l'air et un gaz toxique/dangereux, puis émettre des informations d'environnement détectées ; un dispositif de protection porté par un individu travaillant dans le lieu toxique/dangereux pour protéger son visage des gaz toxiques/dangereux, ce dispositif détectant des informations biométriques relatives à l'individu et émettant les informations détectées ; un collecteur d'informations placé à l'extérieur du lieu de travail pour collecter, filtrer et émettre les informations détectées transmises respectivement par le capteur de gaz et le dispositif de protection ; et un serveur de gestion destiné à recevoir les informations détectées qui ont été collectées et émises par le collecteur d'informations, à analyser les informations d'environnement reçues ainsi que les informations biométriques relatives aux employés, de sorte à contrôler en temps réel les conditions ambiantes du lieu de travail toxique/dangereux ainsi que les conditions sanitaires dans lesquelles travaillent les employés, à envoyer un message au dispositif de protection ou au capteur de gaz par l'intermédiaire du collecteur d'informations, en fonction des résultats du contrôle, si une certaine situation ou un incident s'est produit ou si un problème de santé a été détecté chez un employé, et à transmettre à un terminal de gérant des informations relatives aux conditions sur le lieu de travail.
