hotte de laboratoire à/ certifiée pour acide perchlorique Explanation: Voici déjà une partie de la réponse : perchloric rated fume hood = hotte (de laboratoire) à acide perchlorique ou certifiée pour l’utilisation d’acide perchlorique. http://www.tp.physique.usherbrooke.ca/securite/travail_en_la... http://www.mkplastics.com/content.php?lang=fr&id=41 Ce sont des hottes de laboratoire spécialement conçues pour limiter les risques d’explosion dans les conduits de la hotte. Wash-down : apparemment un système de lavage pour ce type de hottes, je n’ai pas encore trouvé le terme en français mais voici une explication en anglais : Perchloric acid fume hoods These units feature a waterwash system in the ductwork. Because perchloric acid fumes settle, and form explosive crystals, it is vital that the ductwork is cleaned internally with a series of sprays. Waterwash These fume hoods have an internal wash system that cleans the interior of the unit, to prevent a build-up of dangerous chemicals. Perchloric Acid Hoods are to be used when handling hot perchloric acid, hot nitric acid, or for routine use of perchloric acid. (...) Make sure that you know how to operate the wash down systems in these hoods. Wash down systems need to be used after any operation in the hood. http://www.esd.uga.edu/chem/fumehood.htm |
