Fuite de propane dans une cuisine collective, ammoniac dans une chambre froide, monoxyde de carbone dans un parking ou une chaufferie : dans tous ces lieux, un d\u00e9tecteur de gaz est le seul moyen d\u2019\u00eatre pr\u00e9venu avant que la situation ne devienne dangereuse.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">Quels gaz surveiller selon l\u2019activit\u00e9 ?<\/h2>\n\n\n\n<ul class=\"wp-block-list\">\n\n<li><strong>GPL (propane, butane)<\/strong> : cuisines professionnelles, restaurants, ateliers utilisant des bouteilles ou des r\u00e9seaux de gaz.<\/li>\n\n\n<li><strong>Monoxyde de carbone (CO)<\/strong> : parkings couverts, chaufferies, locaux avec chaudi\u00e8res ou groupes \u00e9lectrog\u00e8nes.<\/li>\n\n\n<li><strong>Ammoniac (NH3)<\/strong> : installations de froid industriel, chambres froides, certaines industries agroalimentaires.<\/li>\n\n\n<li><strong>Dioxyde d\u2019azote (NO2)<\/strong> : parkings et locaux o\u00f9 circulent des v\u00e9hicules \u00e0 moteur thermique.<\/li>\n\n<\/ul>\n\n\n\n<h2 class=\"wp-block-heading\">Comment fonctionne une installation de d\u00e9tection de gaz ?<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">Le principe est simple. Des d\u00e9tecteurs plac\u00e9s dans les zones \u00e0 risque mesurent en continu la concentration d\u2019un gaz et envoient l\u2019information \u00e0 une centrale. Lorsque le seuil r\u00e9gl\u00e9 est d\u00e9pass\u00e9, la centrale d\u00e9clenche une alarme sonore et lumineuse et peut commander des actions automatiques, comme couper une \u00e9lectrovanne ou lancer une ventilation.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">O\u00f9 placer les d\u00e9tecteurs ?<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">L\u2019emplacement d\u00e9pend de la densit\u00e9 du gaz par rapport \u00e0 l\u2019air, et c\u2019est un point essentiel :<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n\n<li>Le <strong>propane et le butane<\/strong> sont plus lourds que l\u2019air : ils s\u2019accumulent pr\u00e8s du sol, le d\u00e9tecteur se place donc en position basse.<\/li>\n\n\n<li>L\u2019<strong>ammoniac<\/strong> est plus l\u00e9ger que l\u2019air : on le d\u00e9tecte plut\u00f4t en partie haute.<\/li>\n\n\n<li>Le <strong>monoxyde de carbone<\/strong> a une densit\u00e9 proche de celle de l\u2019air : on le place g\u00e9n\u00e9ralement \u00e0 hauteur de respiration.<\/li>\n\n<\/ul>\n\n\n\n<p class=\"wp-block-paragraph\">Ces principes sont g\u00e9n\u00e9raux : suivez toujours la fiche technique du fabricant et tenez compte des particularit\u00e9s de votre local (ventilation, obstacles, sources possibles de fuite).<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">Les crit\u00e8res de choix<\/h2>\n\n\n\n<ul class=\"wp-block-list\">\n\n<li>Le type de gaz \u00e0 d\u00e9tecter et la plage de mesure adapt\u00e9e.<\/li>\n\n\n<li>L\u2019environnement : poussi\u00e8re, humidit\u00e9, temp\u00e9ratures basses ou zone o\u00f9 une atmosph\u00e8re explosive est possible.<\/li>\n\n\n<li>Le nombre de points de d\u00e9tection et la centrale capable de les g\u00e9rer.<\/li>\n\n\n<li>Les sorties disponibles : relais pour \u00e9lectrovanne, ventilation, report d\u2019alarme.<\/li>\n\n<\/ul>\n\n\n\n<h2 class=\"wp-block-heading\">Un entretien r\u00e9gulier<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">Les capteurs de gaz vieillissent et d\u00e9rivent avec le temps.
