E-fact 54 La maintenance peut être définie comme le fait de travailler sur une chose pour la conserver dans un état fonctionnel et sûr et la préserver de tout dysfonctionnement ou déclin. Cette «chose» peut être un lieu de travail, un équipement de travail ou un moyen de transport (p. ex. un bateau). La maintenance ne relève pas de la responsabilité exclusive des installateurs et des mécaniciens. Elle concerne pratiquement tous les travailleurs et pratiquement tous les environnements de travail. La santé...
This paper describes an experiment to examine whether a visual warning system can improve detection of moving machine hazards that could result in struck-by or pinning accidents. Thirty-six participants, twelve each in one of three age groups, participated in the study. A visual warning system capable of providing four different modes of warning was installed on a continuous mining machine that is used to mine coal. The speed of detecting various machine movements was recorded with and without the visual warning system. The average speed of detection for forward and reverse machine movements was...
Development of a worked example The Health and Safety Laboratory (HSL) were originally approached by the Health and Safety Executive (HSE) to assist with the implementation of Safety Performance Indicators (SPIs) within the Explosives industry. This work builds on the examples and indicators identified in previous work (Ferguson and Nash, 2008), and aimed to encapsulate the types of activities common to a large number of organisations. Previous work to generate Safety Performance Indicators (SPIs) had resulted in little consistency or commonality across the industry group in terms of the leading...
The safety status of a dynamic mechanical system is determined by its historical, current and future states together. Therefore the safety assessment process of such system should have dynamic and diachronic characteristics, which helps to track the dynamic states of system and predict future probable danger in advance. In order to overcome the disadvantages of traditional static safety assessment approaches, the results from which are often delayed and prone to produce false alarms, an adaptive online safety assessment method is proposed in this paper, which consists of two steps. A dynamic adaptive...
This code of practice is intended to provide guidance on safety and health in the use of machinery at the workplace. A Meeting of Experts on Safety in the Use of Machinery was convened in Geneva from 29 November to 7 December 2011 and adopted a code of practice on safety and health in the use of machinery.

Relationship between agency and finger BACKGROUND: The aim of this study was to define the risk factors for occupational hand injuries and explore the relationship between the machines and the fingers injured, based on the records of a hospital in Turkey specialized in hand and microsurgery. METHODS: Five thousand twenty seven occupational hand injuries treated at a hand and microsurgery hospital between 1992 and 2005 were included in the study. All the injuries were retrospectively recoded according to ICD-10, (ICECI) and ILO recommendations. Logistic regression and chi-square for trend analysis...
Objective: The aim of this study was to quantify potential transient risk factors for occupational acute hand injury among hospitalized workers in the People's Republic of China (PRC). Methods: Participants were recruited from 11 medical facilities in 3 cities of the PRC. A face-to-face interview was used to collect information on the occurrence of 8 potential risk factors within a 90-minute time period before an acute traumatic hand injury and during a control period within the month before the injury. The reliability of reporting transient risk factors was assessed, and a case-crossover design...
There is a need for adequate protection of people from the health and safety risks associated with collaborative robot systems. Standard ISO 10218 (Parts 1 and 2) and a draft Technical Specification TS 15066 'Collaborative robots' have been developed to deal specifically with this situation. This study explored the safety, reliability and evidence for the force limits defined by the draft TS 15066, and of the methods for testing them. It also addressed whether the proposed approach in the draft TS 15066 is likely to adequately protect people from the risks. Risk assessment of potential...
The International Powered Access Federation (IPAF) has begun a systematic project to collect worldwide data on accidents/incidents involving mobile elevating work platforms (MEWPs), also known as aerial work platforms (AWPs), with the aim of improving the safe use of equipment. Manufacturers, rental companies, contractors and users are encouraged to report any known MEWP accidents or incidents using the standard form that is available at www.ipaf.org/accident . In the initial phase, IPAF is calling for reports of any known serious accidents and fatalities involving MEWPs in the UK, and any known...
Guards on machine tools are meant to protect persons from injuries caused by parts ejected with high kinetic energy from the machine's working zone. With respect to stationary grinding machines, Standard No. EN 13218:2002, therefore, specifies minimum wall thicknesses for guards. These values are mainly based on estimations and experience instead of systematic experimental investigations. This paper shows to what extent simple impact tests with standardizable projectiles can be used as basis for the evaluation of the impact resistance of guards, provided that not only the kinetic energy of...
Longtemps restée dans le domaine de l'empirisme, l'utilisation des engins fait aujourd'hui l'objet de règles nombreuses touchant à la fois au choix, aux vérifications et à la maintenance du matériel, à la formation du personnel, ainsi qu'à la conduite proprement dite. C'est pourquoi ce manuel comprend deux parties : l'une consacrée aux aspects purement réglementaires, l'autre plus spécifiquement dédiée aux règles de bonnes pratiques en matière de conduite d'engins...
La rubrique « Innovation et technologie », dépendant de « Produits et services », vient d'être mise en ligne. Elle a pour objectif de présenter les dispositifs techniques de prévention conçus par l'INRS puis fabriqués et diffusés par des partenaires industriels. Une dizaine de produits sont actuellement décrits. Afin d'aider les entreprises à mieux maîtriser les risques professionnels, l'INRS conçoit des solutions techniques de prévention, innovantes et fiables. Certaines sont...
Souhaitant établir une procédure sécuritaire pour les interventions dans les zones dangereuses des presses à imprimer, comportant de nombreux angles rentrants, l’Association sectorielle paritaire (ASP) imprimerie et activités connexes a recensé les pratiques les plus sûres pour les effectuer. La méthode de l’arbre des fautes (ou arbre de défaillance), mise à l’épreuve dans 25 entreprises du secteur, s’est avérée concluante à cet égard. L’ASP a donc fait appel à...
Ceux qui ont à choisir les modèles et les emplacements des ponts élévateurs sont soumis à un questionnement dont les conséquences sont importantes. Quels modèles choisir ? Où les installer? Voici quelques erreurs qui peuvent facilement être évitées. Source : http://autoprevention.qc.ca/articles/AP_2011-12_PontsElevateurs_Pieges.pdf
The International Labor Organization (ILO) has posted online, a Draft code of practice on safety in the use of machinery. The draft document: • provides guidance on safety in the use of machinery at the workplace; • includes recommendations and requirements regarding the obligations, responsibilities, and rights of competent authorities, designers, manufacturers,suppliers,employers, and workers; • sets out technical requirements/information on the protection of workers against hazards, risk assessments, characteristics of guards and protective devices; • provides safety requirements...
