Food processing machinery - Slicing machines - Safety and hygiene requirements

This document specifies the safety and hygiene requirements for the design and manufacture, installation, training, use, cleaning and maintenance of slicing machines which are fitted with a motor-driven blade of more than 150 mm in diameter, provided with a product support. These types of slicing machines are intended to be used in shops, restaurants, supermarkets, canteens, etc. to slice foodstuffs.
This document deals with all significant hazards, hazardous situations and events relevant to slicing machines, when they are used as intended by the manufacturer (see Clause 4).
This document applies to the hazards arising during all the phases of the life of the machine as described in EN ISO 12100:2010, 5.4.
Automatic industrial slicing machines covered by EN 16743:2016 are excluded from the scope of this document.
This document covers the following types of slicing machines:
-   horizontal feed slicing machine (see Figure 1);
-   gravity feed slicing machine (see Figure 2).
Both types can have an either hand-operated or power-operated carriage to move the product towards the blade. They both can be fitted with manual or automatic devices to receive and convey the slices away from the machine. All these types can also be provided with a scale.
This document applies to machines which are manufactured after the date of issue of this document.

Nahrungsmittelmaschinen- Aufschnittschneidemaschinen - Sicherheits- und Hygieneanforderungen

Dieses Dokument legt die Sicherheits- und Hygieneanforderungen für die Gestaltung und Herstellung, Aufstellung, Schulung, Verwendung, Reinigung und Instandhaltung von Aufschnittschneidemaschinen mit einem motorbetriebenen Rundmesser von mehr als 150 mm Durchmesser mit einem Produkthalter fest. Diese Typen von Aufschnittschneidemaschinen sind für den Einsatz in Geschäften, Restaurants, Supermärkten, Kantinen usw. zum Schneiden von Lebensmitteln bestimmt.
Dieses Dokument behandelt alle signifikanten Gefährdungen, Gefährdungssituationen und Gefährdungsereignisse mit Bezug zu Aufschnittschneidemaschinen, wenn sie wie vom Hersteller bestimmt verwendet werden (siehe Abschnitt 4).
Dieses Dokument gilt für Gefährdungen, die während aller Phasen der Lebensdauer der Maschine auftreten, wie in EN ISO 12100:2010, 5.4 beschrieben.
Die in der Norm EN 16743:2016 behandelten automatischen industriellen Aufschnittschneidemaschinen sind von dem Anwendungsbereich dieses Dokuments ausgenommen.
Dieses Dokument umfasst die folgenden Aufschnittschneidemaschinentypen:
—   Horizontalschneider (siehe Bild 1);
—   Schwerkraftschneider (siehe Bild 2).
Beide Typen können mit einem handbetriebenen oder motorbetriebenen Schlitten ausgestattet sein, um das Produkt dem Messer zuzuführen. Beide Typen können mit manuellen oder automatischen Vorrichtungen ausgestattet sein, um die Scheiben aufzunehmen und von der Maschine wegzuführen. Alle Typen können darüber hinaus mit einer Waage ausgestattet sein.
Dieses Dokument gilt für Maschinen, die nach dem Ausgabedatum dieses Dokuments hergestellt werden.

Machines pour les produits alimentaires - Trancheurs - Prescriptions relatives à la sécurité et à l’hygiène

Le présent document spécifie les exigences de sécurité et d’hygiène relatives à la conception et la fabrication, l’installation, la formation, l’utilisation, le nettoyage et la maintenance des trancheurs équipés d’un couteau motorisé de diamètre supérieur à 150 mm et d’un support du produit. Ces types de trancheurs sont normalement destinés à être utilisés dans les magasins, restaurants, supermarchés, cantines, etc. pour trancher des aliments.
Le présent document traite de tous les phénomènes, situations et événements dangereux significatifs spécifiques aux trancheurs, lorsqu’ils sont utilisés comme prévu par le fabricant (voir Article 4).
Le présent document s’applique aux phénomènes dangereux se produisant tout au long de la durée de vie de la machine comme décrit dans l’EN ISO 12100:2010, 5.4.
Les trancheurs automatiques industriels couverts par l’EN 16743:2016 sont exclus du domaine d’application du présent document.
Le présent document couvre les différents types de trancheurs suivants :
-   trancheurs à alimentation horizontale (voir Figure 1) ;
-   trancheurs à alimentation par gravité (voir Figure 2).
Les deux types de trancheurs peuvent être équipés d’un chariot manœuvré manuellement ou motorisé pour amener le produit vers le couteau. Les deux types de trancheurs peuvent être équipés de dispositifs manuels ou automatiques pour recevoir les tranches et les éloigner de la machine. Ils peuvent également être équipés d’une balance.
Le présent document s’applique aux machines fabriquées après la date de sa publication.
