Food processing machinery - Automatic back splitting machines of butchery carcasses - Safety and hygiene requirements

This European standard applies to automatic back splitting machines and specifies safety and health requirements for  machines used in slaughterhouses in order to fully automatically split meat animal (beef and pork) along the back-bone axis, splitting the carcass into two parts (see Figure 1).
This document deals with all significant hazards, hazardous situations and events relevant to automatic back splitting machines, when they are used as intended and under conditions of misuse which are reasonably foreseeable by the manufacturer (see Clause 4).
This document deals with the significant hazards, hazardous situations and events during transport, assembly and installation, commissioning and use as defined in EN ISO 12100-1, Clause 5.3.
This document is not applicable to automatic back splitting machines, which are manufactured before the date of its publication as EN.
The machines concerned by this standard are those used in slaughterhouses. They are fitted with a cutting device and are driven by electric, hydraulic and/or pneumatic energy.
The utilized cutting tools are:
-   circular saws,
-   splitting tools.
Three types of machines are considered (see Figures 1 to 5):
-   Splitting machines for pork carcasses, type A (splitter),
-   Splitting machines for pork carcasses, type B (circular saw),
-   Splitting machines for beef carcasses, type C (circular saw).
There are two different operation cycles:
-   carcasses can be splitted when they are at standstill.(In general they are hanging on a sequence conveyed transport system.);
-   carcasses can also be splitted during their continuous movement by conveyor. In this case the movement of the tool is synchronized with that of the carcass.
When the split is finished, the cutting tool returns automatically to its initial position.
The machines run automatically. Under normal operating conditions there is no manual intervention.

Nahrungsmittelmaschinen - Automatische Rückenspaltmaschinen für Schlachttierkörper - Sicherheits- und Hygieneanforderungen

1.1   Allgemeines
Diese Europäische Norm betrifft automatische Rückenspaltmaschinen und spezifiziert Sicherheits- und Gesundheitsanforderungen an Maschinen, die in Schlachthöfen zur automatischen Rückenspaltung von Schlachttieren (Rinder und Schweine) entlang der Wirbel¬säule verwendet werden, wobei der Tierkörper in zwei Teile gespalten wird (siehe Bild 1).
Dieses Dokument behandelt alle signifikanten Gefährdungen, Gefährdungssituationen und Gefährdungs-ereignisse, die auf automatische Rückenspaltmaschinen zutreffen, wenn sie bestimmungsgemäß und ent-sprechend vernünftigen, vorhersehbaren Bedingungen des Herstellers verwendet werden (siehe Abschnitt 4).
Dieses Dokument behandelt die signifikanten Gefährdungen, Gefährdungssituationen und Gefähr-dungsereignisse während Transport, Zusammenbau und Aufstellung, Inbetriebnahme und Gebrauch, wie in EN ISO 12100-1:2003, Abschnitt 5.3, beschrieben.
Dieses Dokument gilt nicht für automatische Rückenspaltmaschinen, die hergestellt wurden, bevor CEN dieses Dokument als EN veröffentlichte.
1.2   Beschreibung der betroffenen Maschinen
Die von dieser Norm erfassten Maschinen werden in Schlachthöfen verwendet. Sie sind mit einer Schneide-vorrichtung versehen und werden elektrisch, hydraulisch oder pneumatisch angetrieben.
Die verwendeten Schneidwerkzeuge sind:
-   Kreissägen;
-   Spalter.
Drei Maschinentypen müssen betrachtet werden (siehe Bild 1 bis 11):
-   Maschinen zum Spalten von Schweinekörpern, Typ A (Spalter);
-   Maschinen zum Spalten von Schweinekörpern, Typ B (Kreissäge);
-   Maschinen zum Spalten von Rinderkörpern, Typ C (Kreissäge).
Es werden zwei Funktionsabläufe unterschieden:
-   Die Tierkörper können in Ruhestellung gespaltet werden. (Im Allgemeinen hängen sie an einem takt-geförderten Transportsystem);
-   Die Tierkörper können auch gespalten werden, während sie kontinuierlich mit einem Förderer bewegt werden; in diesem Falle bewegt sich das Spaltwerkzeug synchron mit dem Tierkörper.

Overview - EN 15166:2008 (Food processing machinery)

EN 15166:2008 is a CEN European standard specifying safety and hygiene requirements for automatic back splitting machines used in slaughterhouses to split pork and beef carcasses along the backbone. It covers machines driven by electric, hydraulic and/or pneumatic power and using circular saws or splitting tools. The standard addresses the full machine lifecycle phases defined in EN ISO 12100-1 (transport, assembly, installation, commissioning and use) and applies to machines manufactured after its publication date.

Key topics and technical requirements

• Scope and machine types: three machine types are defined - pork splitter (type A), pork circular saw (type B) and beef circular saw (type C). Operation modes include splitting at standstill or during continuous conveyor movement with tool synchronization.
• Hazard identification: mechanical hazards (cutting, ejection, moving parts), electrical and control-system hazards, hydraulic/pneumatic risks, loss of stability, noise, ergonomic and hygiene-related hazards (microbial, chemical, physical).
• Zoned protection approach:
  • Zone 1 - Effective range of the splitting tool (primary cutting risk)
  • Zone 2 - Driving and guiding mechanisms
  • Zone 3 - Ejection zone for tools or bone particles The standard specifies protective measures, guards, interlocking devices and safe tool containment for each zone.
• Control and electrical safety: requirements for stopping functions, emergency stop devices, IP ratings for water ingress, safety-related parts of control systems and electromagnetic considerations.
• Hygiene and cleanability: materials, surface finishes, food/splash/non-food area design principles, and cleaning requirements (see Annex B for cleanability design principles).
• Noise: measurement and declaration procedure (Annex A) and noise mitigation requirements.
• Verification and documentation: testing methods, verification of safety/hygiene measures, operator instructions, marking and training requirements.

Applications and who uses EN 15166

• Machine manufacturers designing and certifying automatic back splitting machines for slaughterhouses.
• Plant safety and hygiene engineers responsible for equipment selection, risk assessment and compliance in meat processing plants.
• Equipment purchasers and integrators specifying machines for automated carcass splitting on conveyor systems.
• Certification bodies and conformity assessors verifying compliance with European safety and hygiene requirements.
• Maintenance and training teams implementing safe operation, cleaning regimes and operator training per the standard.

Related standards and regulatory links

• EN ISO 12100-1 (risk assessment and machine lifecycle phases) - referenced for scope and hazard analysis.
• EU Machinery Directive 2006/42/EC and earlier Directive 98/37/EC - Annexes map the standard to Essential Requirements for conformity.
