(Main)Maintenance - Risk control processes of energies and fluids risks in maintenance activities - Guidance
Maintenance - Risk control processes of energies and fluids risks in maintenance activities - Guidance
This document provides users with guidance that help prevent risks related to energies during maintenance activities on plants when in use. It is up to 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 energy 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 worker as regards energies.
This document deals with the prevention of energies and fluids (powders, gases, liquids) related risks; it is noted that some are covered by specific regulations or standards, such as the electrical risk. Environmental issues related to energies and fluids are not in the scope of this document.
The recommendations stated in this document have been drawn up with a view to ensure the safety and health of workers around hazardous energies and fluids, and situations when they are conducting activities on maintenance, settings, 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 supplied, contained, transported or released by plants, products and fluids;
- Risks of lack of presence of vital elements for the worker (breathable air);
- Risks related to the presence of hazardous fluids for the worker and the surrounding personal.
This document is a methodological guideline within the normative maintenance corpus.
Instandhaltung - Verfahren zur Kontrolle der Risiken von Energien und Fluide bei Instandhaltungsaufgaben - Leitfaden
Dieses Dokument enthält einen Leitfaden für die Anwender, der dazu beiträgt, Risiken im Zusammenhang mit Energien bei Instandhaltungsarbeiten an in Betrieb befindlichen Anlagen zu vermeiden. Entsprechend den im Unternehmen üblicherweise verwendeten Begriffen obliegt es jedem Arbeitgeber,
- die Übersteinstimmung zwischen den in diesem Dokument beschriebenen Prozessen und den üblichen Vorgehensweisen zu bestimmen;
- die Aufgaben und Verantwortlichkeiten der an dem Energie Lockout Prozess beteiligten Personen festzulegen.
Dieses Dokument bezieht sich auf Konzepte, Definitionen, Regeln, Empfehlungen und bewährte Vorgehensweisen aus nationalen und internationalen Dokumenten (Lockout/Tagout - "Organisation des Lockouts" - Lockout/Tagout (LOTO) - sichere Isolierung), die Vorgänge zur Gewährleistung der Arbeitssicherheit in Bezug auf Energien abdecken.
Dieses Dokument befasst sich mit der Vorbeugung von Risiken, die mit Energien und Fluiden (Pulver, Gase, Flüssigkeiten) 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 in diesem Dokument gegebenen Empfehlungen wurden mit dem Ziel erarbeitet, die Sicherheit und Gesundheit von Arbeitnehmern in der Nähe von gefährlichen Energien und Fluiden sowie in Situationen sicherzustellen, in denen sie Instandhaltungs , Einstellungs und Formatwechselarbeiten durchführen, unabhängig von der Art der Tätigkeit.
Die Empfehlungen beziehen sich auf Tätigkeiten, die an Objekten durchgeführt werden. Sie werden vor, während und nach den Arbeiten in Hinblick auf Folgendes angewendet:
- die von Anlagen, Produkten und Fluiden zugeführten, enthaltenen, transportierten oder freigesetzten Energien;
- Risiken eines Mangels an lebenswichtigen Elementen für den Arbeitnehmer (Atemluft);
- Risiken für den Arbeitnehmer und das Personal in der Umgebung in Zusammenhang mit gefährlichen Fluiden.
Bei diesem Dokument handelt es sich um einen methodischen Leitfaden im Rahmen des normativen Korpus der Instandhaltung.
Maintenance - Processus de maîtrise des énergies et fluides lors des interventions de maintenance - Recommandations
Le présent document fournit aux utilisateurs des recommandations visant à se prémunir des risques liés aux énergies, lors des opérations de maintenance sur des installations en cours d’utilisation. En fonction de la terminologie couramment utilisée dans l’entreprise, il appartient à 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.
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.
Le présent document traite de la prévention des risques liés aux énergies et aux fluides (poudres, gaz et liquides) ; 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.
Les recommandations spécifiées 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 effectuent des opérations de maintenance, de réglage, 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 fournies, contenues, transportées ou libérées par des installations, des produits et des fluides ;
— aux risques d’absence d’éléments vitaux pour l’intervenant (air respirable) ;
— aux risques liés à la présence de substances dangereuses pour l’intervenant et le personnel évoluant à proximité.
Le présent document est un guide méthodologique entrant dans le corpus des normes de maintenance.
