DANGER

Bien que certains produits Hach soient conçus et certifiés pour être installés dans des endroits dangereux tels que définis par le National Electric Code, de nombreux produits Hach ne conviennent pas pour de tels endroits. Il relève de la responsabilité des personnes qui placent les produits dans des endroits dangereux de déterminer s'ils sont adaptés à cet environnement. En outre, à des fins de sécurité, le placement de machines dans des endroits dangereux doit s'effectuer dans le respect des consignes des schémas de contrôle du fabricant. Toute modification apportée aux machines ou tout déplacement de celles-ci est déconseillé, car susceptible de provoquer des accidents matériels et/ou corporels.

PELIGRO

Aunque algunos productos Hach están diseñados y homologados para su instalación en entornos peligrosos, entendidos éstos conforme a la definición del “National Electrical Code” (Reglamento Eléctrico Nacional), muchos de los productos Hach no son aptos para su utilización en lugares peligrosos. Es responsabilidad de quienes instalen los productos en entornos peligrosos el asegurarse de la idoneidad de dichos productos para este tipo de entorno. Además, para garantizar la seguridad, la instalación de los instrumentos en lugares peligrosos deberá realizarse conforme a las especificaciones del plano del fabricante. Se desaconseja cualquier modificación de los instrumentos o de la instalación, ya que podría provocar lesiones corporales graves, e incluso fatales, y/o daños materiales a los equipos.

GEFAHR

Einige Hach-Produkte sind für den Einbau in explosionsgefährdeten Bereichen gemäß den Festlegungen des National Electrical Code speziell geprüft und zugelassen. Dies gilt jedoch keineswegs für das gesamte Hach-Produktangebot. Die Entscheidung, ob ein Produkt für den Einsatz in explosionsgefährden Bereichen geeignet ist oder nicht, bleibt in die Verantwortung des jeweiligen Installateurs gestellt. Im Interesse der Sicherheit ist es zudem erforderlich, dass ein etwaiger Einbau des Geräts in explosionsgefährdeten Bereichen genau nach den Steuerungsanlagen-Zeichnungen des Herstellers erfolgt. Von der Vornahme von Änderungen an meß- bzw. regeltechnischen Geräten bzw. abweichender Installation wird dringend abgeraten, da hierdurch lebensbedrohliche Personen- und/oder Sachschäden verursacht werden können!

PERICOLO

Nonostante alcuni prodotti Hach, siano predisposti e certificati per l'installazione in ambienti pericolosi, come previsto dal Codice Normativo Nazionale che concerne l'elettricità, è sconsigliabile utilizzare prodotti Hach in ambienti considerati pericolosi. E' diretta responsabilità della persona che installa lo strumento in un luogo ritenuto “pericoloso” appurare se lo strumento

ècompatibile con tale ambiente. Inoltre, per maggior sicurezza, l'installazione dello strumento in ambienti pericolosi deve seguire le specifiche di progettazione del produttore. Si deve evitare qualunque manomissione allo strumento o all'installazione, tali modifiche possono rappresentare una minaccia per la vita delle persone e creare guasti.

2.4.4 Confined Space Entry

Important Note: The following information is provided to guide users of 900 Composite Samplers on the dangers and risks associated with entry into confined spaces.

On April 15, 1993, OSHA's final ruling on CFR 1910.146, Permit Required Confined Spaces, became law. This new standard directly affects more than 250,000 industrial sites in the United States and was created to protect the health and safety of workers in confined spaces.
