Title
(EN) SYSTEM AND METHOD FOR PERSONAL PROTECTIVE EQUIPMENT
(FR) SYSTÈME ET PROCÉDÉ DESTINÉS À UN ÉQUIPEMENT DE PROTECTION INDIVIDUELLE
Abstract
(EN) A method for use with a personal protective equipment (PPE) article includes determining, via at least one sensor, a first parameter indicative of a concentration of at least one substance in an ambient environment of the PPE article. The method further includes determining, via a processor, a second parameter indicative of a second order derivative of the first parameter with respect to time. The method further includes retrieving, via the processor, a first threshold value indicative of a protection threshold provided by the PPE article for the at least one substance. The method further includes comparing, via the processor, the second parameter with the first threshold value. The method further includes generating, via the processor, an alert signal based on the comparison of the second parameter with the first threshold value. The method further includes providing, via a user interface, an alert to a user of the PPE article.
(FR) Procédé utilisable avec un article d'équipement de protection individuelle (EPI) et consistant à déterminer, par au moins un capteur, un premier paramètre indiquant une concentration d'au moins une substance dans un environnement ambiant de l'article d'EPI. Le procédé consiste en outre à déterminer, par un processeur, un second paramètre indiquant une dérivée seconde du premier paramètre par rapport au temps. Le procédé consiste en outre à récupérer, par le processeur, une première valeur seuil indiquant un seuil de protection fourni par l'article d'EPI pour l'au moins une substance. Le procédé consiste en outre à comparer, par le processeur, le second paramètre à la première valeur seuil. Le procédé consiste en outre à générer, par le processeur, un signal d'alerte selon la comparaison du second paramètre à la première valeur seuil. Le procédé consiste en outre à fournir, par une interface utilisateur, une alerte à un utilisateur de l'article d'EPI.
