Maintenance - Risk control processes of energies and fluids risks in maintenance activities - Guidance

Edition date: 2025-06-04
In Force
Available languages: German, French, English
Summary: This document provides users with guidance that help manage risks related to energies & fluids during maintenance activities on items when in use. It is the responsibility of each employer, according to the terms commonly used in the company, to: - Set out the correlation between the processes described in this document and standard practices, - Define the roles and responsibilities of the people involved in the energies & fluids lockout process. This document refers to concepts, definitions, rules, recommendations, and best practices taken from national and international documents (lockout/tagout - "administrative lockout" - Lockout/Tagout (LOTO) - Safe isolation) that cover activities to ensure the safety of workers with respect to energies & fluids. This document deals with the prevention of energy & fluid (e.g. powders, gases, liquids, etc.) related risks; it is noted that some are covered by specific regulations or standards, such as the electrical risk. Environmental issues related to energies & fluids are not in the scope of this document. Danger associated with energies & fluids can be direct (e.g. contact, absorption, etc.) or indirect by reaction (e.g. mixing, heating, etc.). The scope includes all fluids because they can be intrinsically dangerous or become dangerous. The recommendations given in this document have been drawn up with a view to ensure the safety and health of workers around hazardous energies & fluids, and situations when they are conducting actions related to maintenance, settings or changing formats, regardless of the type of activity. The recommendations relate to activities carried out on items. They are applied before, during and after the operation to: - The energies & fluids supplied, contained, transported, or released by items, products, - Risks related to the presence of hazardous energies & fluids for the worker and the surrounding personal. This document is a methodological guideline within the maintenance standards. NOTE Particular cases such as risks of lack of presence of vital elements for the worker (e.g. breathable air) are in the scope but will not be detailed.

Dieses Dokument bietet einen Leitfaden für Anwendende, der dazu beiträgt, mit Risiken im Zusammenhang mit Energien und Fluiden bei Instandhaltungsarbeiten an in Betrieb befindlichen Objekten umzugehen. Entsprechend den im Unternehmen üblicherweise verwendeten Begriffen trägt jeder Arbeitgeber die Verantwortung dafür, - die Übersteinstimmung zwischen den in diesem Dokument beschriebenen Prozessen und den üblichen Vorgehensweisen zu bestimmen; - die Aufgaben und Verantwortlichkeiten der an dem Energie- und Fluid-Lockout-Prozess beteiligten Personen festzulegen. Dieses Dokument stellt Konzepte, Definitionen, Regeln, Empfehlungen und bewährte Vorgehensweisen aus nationalen und internationalen Dokumenten auf (Lockout/Tagout – „Organisation des Lockouts“ – Lockout/Tagout (LOTO) – sichere Isolierung), die Vorgänge zur Sicherstellung der Arbeitssicherheit in Bezug auf Energien und Fluide abdecken. Dieses Dokument ist anwendbar auf die Vorbeugung von Risiken, die mit Energien und Fluiden (z. B. Pulver, Gase, Flüssigkeiten usw.) in Zusammenhang stehen; es ist anzumerken, dass einige davon, wie beispielsweise elektrische Risiken, Gegenstand spezifischer Vorschriften oder Normen sind. Mit Energien und Fluiden in Zusammenhang stehende Umweltfragen fallen nicht in den Anwendungsbereich dieses Dokumentes. Die mit Energien und Fluiden verbundenen Gefährdungen können direkt sein (z. B. Kontakt, Absorption usw.) oder indirekt durch Reaktion (z. B. Mischen, Erwärmen usw.). Der Anwendungsbereich umfasst jegliche Fluide, weil sie an sich gefährlich sein oder gefährlich werden können. Die in diesem Dokument gegebenen Empfehlungen wurden mit dem Ziel erarbeitet, die Sicherheit und Gesundheit des Personals in der Nähe von gefährlichen Energien und Fluiden sowie in Situationen, in denen sie Instandhaltungs-, Einstellungs- oder Formatwechselarbeiten durchführen, sicherzustellen, unabhängig von der Art der Maßnahme. Die Empfehlungen beziehen sich auf Tätigkeiten, die an Objekten durchgeführt werden. Sie werden vor, während und nach den Vorgängen in Hinblick auf Folgendes angewendet: - die von/in Objekten und Produkten zugeführten, enthaltenen, transportierten oder freigesetzten Energien und Fluide; - Risiken für das Personal und die Belegschaft in der Umgebung in Zusammenhang mit gefährlichen Energien und Fluiden. Bei diesem Dokument handelt es sich um einen methodischen Leitfaden im Rahmen von Instandhaltungsnormen. ANMERKUNG Spezielle Fälle wie das Risiko des Nichtvorhandenseins lebenswichtiger Elemente für das Personal (z. B. Atemluft) fallen in den Anwendungsbereich, werden jedoch nicht im Einzelnen dargelegt.

Le présent document fournit aux utilisateurs des recommandations visant à maîtriser les risques liés aux énergies et aux fluides, lors des opérations de maintenance sur des biens en cours d’utilisation. En fonction de la terminologie couramment utilisée dans l’entreprise, il est de la responsabilité de chaque employeur : - d’établir la corrélation entre les processus décrits dans le présent document et les pratiques usuelles ; - de définir les fonctions et responsabilités des personnes impliquées dans les processus de mise en sécurité des énergies et des fluides. Le présent document se réfère à des concepts, des définitions, des règles, des recommandations et des bonnes pratiques issus de documents nationaux et internationaux (consignation - « condamnation administrative » - LOTO (condamnation/signalisation) - isolation sûre) qui traitent des opérations de mise en sécurité des intervenants vis‐à‐vis des énergies et des fluides. Le présent document traite de la prévention des risques liés aux énergies et aux fluides (poudres, gaz et liquides, par exemple) ; il faut noter que certains risques, tels que le risque électrique, sont couverts par des réglementations ou des normes spécifiques. Les enjeux environnementaux liés aux énergies et aux fluides n’entrent pas dans le domaine d’application du présent document. Le danger associé aux énergies et aux fluides peut être direct (par exemple contact, absorption, etc.) ou indirect par réaction (par exemple mélange, échauffement, etc.). Le domaine d’application englobe tous les fluides car ils peuvent être intrinsèquement dangereux ou ils peuvent le devenir. Les recommandations formulées dans le présent document ont été rédigées dans le but d’assurer la sécurité et de protéger la santé des intervenants évoluant à proximité d’énergies et de fluides dangereux, ainsi que dans les situations où ils réalisent des actions assimilables à de la maintenance, de réglage ou de changement de formats, quelle que soit la nature des activités. Les recommandations portent sur les opérations réalisées sur des biens. Elles s’appliquent avant, pendant et après l’opération : - aux énergies et aux fluides fournis, contenus, transportés ou libérés par des biens ou des produits ; - aux risques liés à la présence d’énergies et de fluides dangereux pour l’intervenant et le personnel évoluant à proximité. Le présent document est un guide méthodologique entrant dans le cadre des normes de maintenance. NOTE Les cas particuliers tels que les risques d’absence d’éléments vitaux pour l’intervenant (air respirable, par exemple) entrent dans le domaine d’application mais ne seront pas détaillés.
