La norme EN ISO 14122-4 a \u00e9t\u00e9 publi\u00e9e en Italie en octobre 2016, remplace la pr\u00e9c\u00e9dente EN ISO 14122-4 de 2010 et n’est pas applicable aux machines fabriqu\u00e9es avant la date de sa publication.

Alors que la norme EN 14122-4 pr\u00e9c\u00e9dente pr\u00e9sente une liste de toutes les dimensions \u00e0 respecter, l’approche adopt\u00e9e par la nouvelle norme consiste \u00e0 fournir un guide pour le choix des principales caract\u00e9ristiques et des \u00e9l\u00e9ments que les \u00e9chelles comporteront.<\/p>\n

Des lignes directrices sont donn\u00e9es pour le choix du type d’\u00e9chelle en fonction de l’espace disponible et pour la d\u00e9finition des espaces \u00e0 respecter entre les diff\u00e9rents \u00e9l\u00e9ments de l’\u00e9chelle et tout autre obstacle fixe pr\u00e9sent dans la zone.<\/p>\n

Un guide est \u00e9galement fourni pour le choix de l’\u00e9quipement de protection individuelle contre les chutes de hauteur et pour l’\u00e9valuation des risques li\u00e9s \u00e0 l’\u00e9chelle<\/strong>, en tenant compte d’aspects tels que l’effort, les dommages dus \u00e0 la chute, la fr\u00e9quence d’utilisation, etc.<\/p>\n

En fonction de la hauteur totale, la nouvelle norme d\u00e9termine les dimensions \u00e0 respecter et les dispositifs de protection \u00e0 adopter. En fonction de la hauteur totale, la nouvelle norme d\u00e9termine les dimensions \u00e0 respecter et les dispositifs de protection \u00e0 adopter, ainsi que l’emplacement des plates-formes de repos.<\/p>\n

NB : Les structures telles que les b\u00e2timents et les parties de machines peuvent constituer une cage de s\u00e9curit\u00e9 en soi, \u00e0 condition que les dimensions obtenues soient les m\u00eames que celles \u00e9tablies par la norme pour la construction des cages de s\u00e9curit\u00e9.<\/strong><\/p>\n<\/div> <\/div>\n \n \n

La norme d\u00e9taille l’essai \u00e0 effectuer, que ce soit avec un ou deux montants.
\nLes poids d’essai et les points d’application sont \u00e9tablis pour les diff\u00e9rents \u00e9l\u00e9ments de l’\u00e9chelle (barreaux et montants) et pour les \u00e9ventuels dispositifs de protection (cages de s\u00e9curit\u00e9 ou garde-corps).<\/p>\n

Les caract\u00e9ristiques g\u00e9om\u00e9triques (conception et construction) de tous les \u00e9l\u00e9ments pouvant former le syst\u00e8me d’\u00e9chelle, des \u00e9chelons aux cages de s\u00e9curit\u00e9, sont d\u00e9taill\u00e9es. Cette section pr\u00e9cise que les dispositifs de protection contre les chutes \u00e0 appliquer \u00e0 la zone d’arriv\u00e9e sont ind\u00e9pendants de tout autre dispositif de protection appliqu\u00e9 \u00e0 l’\u00e9chelle. Par cons\u00e9quent, il n’est pas possible d’\u00e9viter d’autres dispositifs de protection contre les chutes simplement parce que, par exemple, il est pr\u00e9vu d’utiliser l’antichute le long de l’\u00e9chelle.<\/p>\n<\/div> <\/div>\n \n \n
