Mechanical vibration - Measurement and calculation of occupational exposure to whole-body vibration with reference to health - Practical guidance

This European Standard provides guidelines for the measurement and evaluation of whole-body vibration at the workplace.
This European Standard describes the precautions to be taken to make representative vibration measurements and to determine the daily exposure time for each operation in order to calculate the daily exposure value standardized to an 8-h reference period. This European Standard provides a means to determine the relevant operations that should be taken into account when determining the vibration exposure.
This European Standard applies to situations where people are exposed to whole-body vibration at the workplace, transmitted through the buttocks for a seated person or through the feet for a standing person.
This European Standard is restricted to the evaluation of exposure to whole-body vibration using quantities derived from frequency-weighted root-mean-square acceleration. The frequency range considered is 0,5 Hz to 80 Hz. Where the vibration includes shocks or impacts, methods in this European Standard may underestimate the severity of the exposure. There is a need to assess the risks arising from exposure to whole-body shocks and high crest factor vibration. Methods for this are beyond the scope of this European Standard.

Mechanische Schwingungen - Messung und rechnerische Ermittlung der Einwirkung von Ganzkörper-Schwingungen auf den Menschen am Arbeitsplatz im Hinblick auf seine Gesundheit - Praxisgerechte Anleitung

Diese Europäischen Norm enthält Anleitungen zur Messung und Bewertung von Ganzkörper-Schwingungen am Arbeitsplatz.
Diese Europäischen Norm beschreibt die zu treffenden Vorkehrungen, um repräsentative Schwingungs-messungen durchzuführen und die tägliche Einwirkungsdauer jeder Tätigkeit zu bestimmen, um daraus den frequenz-bewerteten energieäquivalenten 8-h-Beschleunigungs-wert zu errechnen. Diese Europäischen Norm stellt Mittel zur Bestimmung der relevanten Tätigkeiten zur Verfügung, die bei der Ermittlung der Schwingungs-belastung einbezogen werden sollten.
Diese Europäischen Norm gilt für Situationen, in denen am Arbeitsplatz Ganzkörper-Schwingungen auf Bedien-personen beim Sitzen über das Gesäß oder beim Stehen über die Füße übertragen werden.
In dieser Europäischen Norm wird die Einwirkung von Ganzkörper-Schwingungen nur mit solchen Größen beschrieben, die aus dem Effektivwert der frequenzbewerteten Beschleunigung abgeleitet sind. Der betrachtete Frequenzbereich beträgt 0,5 Hz bis 80 Hz. Wenn die Schwingungseinwirkung stoß- oder impulshaltig ist und hohe Beschleunigungsspitzen aufweist, liefert die reine Effektivwert-bildung in der Regel einen zu kleinen Wert für die Schwingungsintensität. Es sind dann Verfahren zur Beurteilung der Risiken bei der Einwirkung von Stößen und Ganzkörper-Schwingungen mit hohem Scheitelfaktor notwendig. Solche Verfahren sind in ISO 2631-1 angegeben, werden aber in dieser Euorpäischen Norm nicht benutzt.
Einzelheiten zur Gültigkeit der Verwendung des Beschleunigungs-Effektivwertes sind in ISO 2631-1 enthalten.

å==NjjtT1 is the total measurement duration This procedure shall be carried out separately for vibration in each of the axes measured.b) Where the daily work consists of operations of shorter duration, which are repeated several times during aworking day, measurements for determination of the 8 h energy-equivalent vibration value can be made overcomplete work cycles. The number of work cycles over which measurements are made shall be sufficient toshow that the average value obtained is representative of the vibration from the operation throughout the day.c) Where no operations are repeated, the vibration from every operation shall be measured.d)Where there is no repeated work cycle of operations of short duration and the individual operations are shorterthan 3 min, the operations can be repeated in order to collect measurements over a minimum of 3 min, seeexample in clause A.3. As an alternative, simulated operations may be organized for making measurements of3 min duration.NOTEThe requirement of a minimum of 3 min is due to statistical reasons.5.5 Estimation of exposure timeThe total daily exposure duration shall be obtained for each operation or work cycle for which a vibration magnitudehas been established. This may be based on;a) a measurement of the actual exposure duration of a single operation or work cycle; andb) information on the number of operations or work cycles per working day.The first of these will be a measurement to determine how long an operator is exposed to vibration, and from whatsource, during a specified period. Various techniques may be used, for example:¾ use of a stopwatch;¾ analysis of video recordings;¾ activity sampling.A source of information may be work records, e.g. the number of lorries loaded and unloaded by fork-lift trucks.However, it is important to ensure that the information is compatible with the information required for an evaluationof daily vibration exposure. For example, work records might give very accurate information on the number ofcompleted work items at the end of each day, but where there is more than one operator, or unfinished work itemsat the end of a shift, this information may not be directly applicable to a vibration exposure evaluation.NOTEOperators asked for information on their typical daily vibration exposure duration will normally give an estimatewhich includes periods of time when there is no vibration (e.g. idling, lifting for a fork-lift truck). Therefore, such an approachoften results in an overestimation of the exposure duration.SIST EN 14253:2004

The EN 14253:2003 standard delivers an essential framework for the measurement and evaluation of occupational exposure to whole-body vibration. Its comprehensive scope covers the methodologies required for assessing vibration exposure, specifically focusing on reducing health risks associated with whole-body vibration in the workplace. One of the primary strengths of this standard is its emphasis on representative vibration measurements. It provides practical guidance to ensure that vibration assessments reflect actual exposure conditions, which is critical for accurate evaluation of daily exposure time for various operations. The standard’s approach of standardizing exposure values to an 8-hour reference period aids in promoting consistency in measurement processes across different work environments. Moreover, EN 14253:2003 effectively addresses the methods for determining relevant operations that are central to assessing vibration exposure. It offers a structured way to identify and categorize activities that contribute to whole-body vibration. This ensures that organizations can prioritize their efforts in mitigating exposure where necessary. The standard specifically focuses on whole-body vibration transmitted through both seated and standing positions, which is particularly relevant in diverse work settings. The defined frequency range of 0.5 Hz to 80 Hz for evaluating frequency-weighted root-mean-square acceleration makes the standard applicable to a wide array of industrial contexts, enhancing its relevance to organizations concerned with worker health and safety. However, it is worth noting that while the standard provides valuable methodologies for evaluating whole-body vibration, it does acknowledge limitations concerning the assessment of shocks and impacts. This points to the necessity for further research and methods to address these aspects rigorously, but falls beyond the scope of this document. In conclusion, the EN 14253:2003 standard stands as a crucial document for organizations aiming to understand and mitigate the health impacts of whole-body vibration in the workplace. It offers solid, practical guidance needed to navigate the complexities of vibration measurement and underscores the importance of rigorous evaluation procedures in occupational health.

La norme EN 14253:2003 sur les vibrations mécaniques propose des lignes directrices essentielles pour la mesure et l'évaluation de l'exposition professionnelle aux vibrations de tout le corps. Cette norme européenne est particulièrement pertinente pour le secteur du travail, car elle aborde directement les impacts potentiels sur la santé des travailleurs exposés à ces vibrations, en tenant compte des différents contextes d'exposition. Le champ d’application de cette norme est clairement défini, se concentrant sur les situations où les individus sont exposés à des vibrations de tout le corps, que ce soit en position assise ou debout. Les précautions mentionnées pour garantir des mesures de vibrations représentatives sont un des points forts de cette norme. Elles permettent de calculer avec précision le temps d'exposition quotidienne pour chaque opération, afin d'obtenir des valeurs d'exposition normalisées sur une période de référence de 8 heures. Cela est crucial pour estimer correctement les risques liés à l'exposition, en fournissant un cadre clair pour l’évaluation. Un autre aspect notable est la méthode de mesure qui repose sur l’accélération quadratique moyenne pondérée en fonction de la fréquence, couvrant une plage de fréquence de 0,5 Hz à 80 Hz. Ce procédé permet d'obtenir des données fiables pour les évaluations, ce qui renforce la validité des résultats. Toutefois, il est important de noter que la norme mentionne aussi ses limites, en spécifiant que les méthodes employées pourraient sous-estimer la sévérité de l'exposition lorsque des chocs ou des impacts sont présents. Ce point encourage les utilisateurs de la norme à être vigilants et à considérer des évaluations complémentaires pour les vibrations à facteur de crête élevé. En résumé, la norme EN 14253:2003 se révèle être un outil précieux pour gérer les risques liés aux vibrations au travail. Avec des lignes directrices claires et des méthodes de mesure standardisées, elle assure une approche systématique et rigoureuse de l’évaluation des expositions aux vibrations, renforçant ainsi la protection de la santé des travailleurs.

SIST EN 14253:2004は、職場での全身振動の測定と評価に関する実用的なガイドラインを提供する重要な欧州標準です。この標準の範囲は、全身振動の職業的曝露を健康に関連付けて測定し、計算することにあり、特に8時間の基準期間に標準化された日次曝露値を算出するための指針を示しています。 この標準の強みは、労働者が座っている場合は尻部から、立っている場合は足から伝達される全身振動に対する曝露を明確に定義し、代表的な振動測定を行うための注意事項を詳述している点です。これにより、職場での全身振動の影響を適切に評価するための基盤が整えられています。 SIST EN 14253:2004は、適切な手法に基づいて振動曝露を評価するための具体的な方法を提供します。周波数加重二乗平均加速度から導出された量を用いることで、特定の周波数範囲（0.5 Hzから80 Hz）における曝露を標準化し、リスク管理に貢献します。 ただし、この標準は、振動に衝撃やインパクトが含まれる場合、曝露の深刻度を過小評価する可能性があるため、注意が必要です。全身の衝撃や高ピークファクター振動によるリスクを評価するための方法は、この標準の範囲外であることを明確に示しています。 このように、SIST EN 14253:2004は、現代の職場における健康管理と安全基準の確立に不可欠な側面を包含しており、全身振動問題に対する意識を高める上で非常に重要な文書です。

EN 14253:2003 표준은 직장에서 앉아 있는 사람의 경우 엉덩이를 통해, 서 있는 사람의 경우 발을 통해 전달되는 전신 진동에 초점을 맞추고 있어, 인간의 건강에 미치는 영향을 평가하는 데 신뢰성 있는 기준을 제공합니다. 다만 진동에 충격이나 임펙트가 포함될 경우, 이 표준은 노출의 심각성을 과소평가할 수 있다는 점을 유의해야 합니다. 이러한 잠재적인 리스크를 따로 평가해야 할 필요가 있으며, 이는 본 표준의 범위를 벗어나는 내용을 포함합니다. 결론적으로, EN 14253:2003 표준은 작업장에서 전신 진동에 대한 건강 노출을 평가하기 위한 중요한 도구로, 산업계 및 연구자들이 더 안전한 작업 환경을 조성하는 데 기여할 수 있는 유용한 가이드를 제공합니다.

Die Norm EN 14253:2003 bietet eine umfassende Leitlinie für die Messung und Bewertung von Ganzkörpervibrationen am Arbeitsplatz, mit einem besonderen Fokus auf den Gesundheitsaspekt. Der Anwendungsbereich dieser europäischen Norm ist klar definiert: Sie richtet sich an Situationen, in denen Personen den Ganzkörpervibrationen ausgesetzt sind, die durch das Gesäß beim Sitzen oder durch die Füße beim Stehen übertragen werden. Dies ist besonders relevant in der Industrie, wo solche Vibrationen häufig vorkommen können. Ein wesentlicher Stärke dieser Norm liegt in den darin beschriebenen Vorsichtsmaßnahmen, um repräsentative Vibrationsmessungen durchführen zu können. Durch die Festlegung der täglichen Expositionszeit für jede Tätigkeit wird es möglich, den täglichen Expositionswert zu berechnen, der auf einen 8-Stunden-Bezugszeitraum standardisiert ist. Dies ermöglicht eine genaue und konsistente Beurteilung der Gesamtexposition der Arbeitnehmer und spielt eine entscheidende Rolle beim Schutz der Gesundheit im Arbeitsumfeld. Die Norm legt außerdem fest, dass die Bewertung der Exposition auf der Grundlage von Frequenz-gewichteten quadratischen Mittelbeschleunigungen erfolgen soll. Der betrachtete Frequenzbereich von 0,5 Hz bis 80 Hz deckt die relevanten Vibrationen ab, die in der Industrie vorkommen können. Diese spezifische Fokussierung auf den Frequenzbereich erhöht die Relevanz der Norm für Praktiker, die in ihrem Arbeitsumfeld mit solchen Vibrationen konfrontiert sind. Ein weiterer Aspekt, der die Norm hervorhebt, ist die Möglichkeit, relevante Tätigkeiten zu identifizieren, die bei der Bestimmung der Vibrationsexposition berücksichtigt werden sollten. Dies trägt zur Sicherheit am Arbeitsplatz bei und kann dazu beitragen, langfristige Gesundheitsprobleme zu verhindern. Es ist wichtig zu beachten, dass die Norm eine Grenze zieht: Sie beschränkt sich auf die Bewertung von Ganzkörpervibrationen und schließt die Untersuchungsmethoden für Stöße und hohe Spitzenspannungen aus. Diese Einschränkung sollte von den Anwendern beachtet werden, da es in bestimmten Situationen notwendig sein könnte, zusätzliche Methoden zur Risikoanalyse zu implementieren. Insgesamt stellt die EN 14253:2003 einen entscheidenden Schritt in der Standardisierung der Messung und Bewertung von Ganzkörpervibrationen am Arbeitsplatz dar und trägt somit signifikant zur Verbesserung des Gesundheitsschutzes bei Arbeitnehmern bei.
