    • Distance de s\u00e9paration dynamique:<\/strong> il s’agit de la distance de s\u00e9paration d\u00e9termin\u00e9e par rapport \u00e0 la limite de la zone dangereuse que les origines des ph\u00e9nom\u00e8nes dangereux peuvent atteindre en fonction de sa position r\u00e9elle et de l’\u00e9volution de cette position pendant le temps de r\u00e9ponse total du syst\u00e8me T<\/em> pour atteindre la r\u00e9duction du risque vis\u00e9e.<\/li>\n<\/ul>\n<\/div> <\/div>\n \n \n

      Le concept de \u00ab plan de r\u00e9f\u00e9rence<\/strong> \u00bb a \u00e9t\u00e9 introduit dans la norme EN ISO 13855 parce que, dans certaines applications, mouvements \u00e0 proximit\u00e9 d’une machine obligent les personnes \u00e0 changer de hauteur pour effectuer les t\u00e2ches pr\u00e9vues, soit en montant, soit en descendant. Par ailleurs, la conception des machines peut permettre aux personnes de changer de hauteur pour acc\u00e9der \u00e0 la zone dangereuse ou pour atteindre une commande manuelle de s\u00e9curit\u00e9.<\/p>\n

      Dans ce cas, le plan de r\u00e9f\u00e9rence, qui g\u00e8re le risque d’atteinte des dangers, doit \u00eatre consid\u00e9r\u00e9 comme le niveau utilis\u00e9 par la personne pour acc\u00e9der \u00e0 ces dangers. Lorsqu’il y a un changement d’\u00e9l\u00e9vation (par exemple, marche, plate-forme, ch\u00e2ssis de machine), le plan de r\u00e9f\u00e9rence doit \u00eatre d\u00e9termin\u00e9 conform\u00e9ment au Tableau 1<\/strong> de la norme.<\/p>\n<\/div> <\/div>\n \n \n

      \n

      La distance d’atteinte<\/strong> a toujours fait r\u00e9f\u00e9rence \u00e0 la distance entre les parties du corps humain et les zones dangereuses potentiellement accessibles. La norme EN ISO 13855 \u00e9tend ce concept pour inclure l\u2019acc\u00e8s \u00e0 un SRMCD<\/strong> depuis un espace prot\u00e9g\u00e9. Les SRMCD, lorsqu’elles sont activ\u00e9es, peuvent pr\u00e9senter un risque nouveau ou accru pour l’op\u00e9rateur. Par cons\u00e9quent, le positionnement et l’emplacement des SRMCD doivent \u00eatre envisag\u00e9s de mani\u00e8re \u00e0 garantir que l’op\u00e9rateur ne puisse pas les atteindre facilement lorsqu’il se trouve dans un espace prot\u00e9g\u00e9.<\/p>\n<\/div> <\/div>\n \n \n
