  • Such respiratory protective devices are used both by fire brigades and in the commercial sector when people are moving in atmospheres that do not allow natural breathing due to a lack of sufficient oxygen in the ambient air. Fire brigades usually combine several people into a task force, which usually has a squad leader.
  • the entire squad is monitored by a surveillance person, communication between the squad leader and the surveillance person usually taking place via radio communication.

Every person to be monitored takes off on the monitoring device at the beginning of its use. This is done by actuating the triggering device with which the time measuring device for measuring the time that has elapsed since logging off is started.

La présente invention concerne un procédé pour surveiller au moins deux personnes qui exercent une activité limitée dans le temps en étant assistées par une source d'air respiratoire externe, en particulier des personnes porteuses d'appareils de protection respiratoire telles que les pompiers, les plongeurs ou analogues. Selon l'invention: les états de remplissage des appareils de protection respiratoire qui alimentent les personnes en air respiratoire, en particulier des bouteilles d'air pressurisé, sont détectés et transmis à une centrale de surveillance, avant que les personnes se rendent sur le lieu d'utilisation des appareils; les personnes, à leur arrivée sur le lieu d'utilisation des appareils, transmettent à la centrale un signal qui indique leur arrivée et sert à calculer le temps qui s'est écoulé entre le moment d'arrivée et le début de prélèvement d'air respiratoire de l'appareil de protection respiratoire. L'invention a pour objet la mise au point d'un procédé pour surveiller au moins deux personnes qui exercent une activité limitée dans le temps en étant assistées par une source d'air respiratoire externe, qui, avec un appareillage relativement simple et compatible notamment avec des appareils préexistants, garantit une sécurité de fonctionnement élevée aux personnes qui travaillent dans des environnements dangereux. A cet effet, le temps de séjour sur le lieu d'utilisation des appareils est calculé d'après la formule tArbeit = VAtemluft min - tAnmarsch - (tAnmarsch <.> alpha ) dQ, tArbeit représentant le temps de séjour sur le lieu d'utilisation des appareils, tAnmarsch représentant le temps pour se rendre sur le lieu d'utilisation des appareils, alpha étant un facteur de sécurité, VAtemluft min représentant la réserve d'air respiratoire dans un appareil de protection respiratoire à réserve minimale et dQ représentant la consommation d'air respiratoire moyenne par unité de temps. La centrale transmet un signal aux personnes à un moment où le retrait de la zone d'utilisation des appareils est sûr.
