Abstract

La présente invention concerne un procédé et un appareil pour détecter la présence de gaz ou vapeurs dans l'air ou d'autres agents gazeux. Cet appareil est caractérisé en ce qu'il comprend, en combinaison, un conteneur résistant au feu, des moyens pour introduire un échantillon d'agent gazeux éventuellement contaminé dans ce conteneur, une vanne pour introduire, dans ce conteneur, une quantité connue d'un gaz de référence ayant des propriétés de combustion connues, afin de le mélanger avec l'agent gazeux qui s'y trouve, des moyens d'allumage associés au conteneur, de manière à permettre au mélange gazeux résultant se trouvant dans le conteneur, de s'allumer s'il est inflammable, et des moyens de détection pour surveiller l'intérieur du conteneur, afin de détecter à l'instant où a lieu l'allumage du mélange gazeux. Applicable à la surveillance d'installation de traitement dans les industries pétrolière et chimique.
