Period
Ca. 1990-2007 in the Rare Books Room
Canada
This artefact is an extinguisher such as the one used to protect the books and other materials in the Rare Book Room (RBR) of the Library & Information Services of the Canada Science and Technology Museum. Their location offers a storage tank for the Halon Fire suppression System. It was installed ca. 1990 and removed in the summer of 2007 prior to such systems being made illegal due to the impact of the upper atmospheric ozone. Cet extincteur est comme celui utiliser pour protéger les livres rares et d'autres matériels au Bibliothèque et Services Informatiques du Musée de la Science et Technologie. Installé dans la (RBR) Rare Book Room autour de 1990, il a été enlevé en 2007 quand l'utilisation de ce genre de système a été banni grâce à leur destruction de l'ozone. Le musée avait un réservoir de stockage à Halon pour le système de suppression de feu.
Function
This artifact is the fire relay control for the Halon 1301 fire extinguisher system. Pulling the pin on the top of this box would manually open or close a circuit inside the box by moving a contactor to activate or deactivate the switch that works with the fire alarm. The switch could be used to both trigger or manually reset the system. L'objet tenu dans cette boite était le relais électrique qui contrôle système pour l'extincteur Halon 1301. En tirant ou en poussant sur la goupille au-dessus de la boite un contacteur en marchait en unisson pour ouvrir ou fermer le circuit à l'intérieur. Ceci activait ou désactivais le réenclenchement manuel qui fonctionnait en unisson avec l'alarme à feu.
Technical
From the 1960s-1970s halon gas was used to protect computer installations in the case of fire. Unlike traditional water fire suppression systems, halon did not damage the electronics or the computers and in the case of libraries with rare books avoided costly water damage. Such systems worked by absorbing all of the oxygen from the air. Being heavier than air, the halon migrated towards the floor and people therefore had to be aware that they needed to evacuate the area immediately that a fire alarm and/or the halon system went off. They had only between 20-30 seconds to evacuate before the oxygen was deleted. Pendant les 1960s et 1970 le gaz a halon étais utilisé pour protéger les ordinateurs, car l'halon n'endommageais pas les systèmes électroniques. Il était vu comme optimale pour les bibliothèques à livres rare, car il ne les endommageait pas en utilisant de l'eau. Ces systèmes fonctionnaient en absorbant toute l'oxygène dans l'air. L'halon est plus pesant que l'air et donc va tomber vers le sol. Après 20 a 30 secondes l'oxygène devenait supprimer de la salle et donc les personnes qui travaillaient sur lieu avaient peu de temps pour évacuer.
