Risk assessment, validation & technical file for a packaging line in the food industry
Machine safety
Prohead Engineering works for both operators and machine builders on complex assemblies that require a CE declaration.
About the case
Context:
A producer in the food industry commissioned a new packaging line. The line consisted of several linked modules for cutting, conveying and packaging food products. Because it is an assembly of machinery, the installation fell under Machinery Directive 2006/42/EC. The client asked Prohead Engineering to guide the process towards CE marking.
Approach:
The project was built around three pillars:
- Risk assessment: all hazards were systematically mapped according to EN ISO 12100, including risks of trapping, cutting, electrocution and emergency stop provisions. For each risk, recommendations were defined and the required performance levels determined.
- Validation: the safety functions in the line control system were validated according to EN ISO 13849-2, such as emergency stop circuits, door switches and light curtains on the conveyors. This included both calculations (PL verification) and functional tests.
- Technical file: all analyses, validation reports and documentation were brought together in a technical file that complies with the Machinery Directive.
Result:
Thanks to this process, the client was able to demonstrate that the packaging line was compliant and safe. The installation received CE marking and could be put into production without further modifications.
Added value:
Prohead Engineering delivered not only compliance but also a practical improvement of the line: interlocks, emergency stop functions and light curtains were tailored to the real risks in a food environment. The result is a system that is both safe and reliable.
