Food and drink manufacturers’ machine safety seminars

Food and drink manufacturers’ machine safety seminars

Last year saw Pilz introduce machine safety seminars aimed at users of machines in the food and beverage production sector, and these are planned to continue in 2016.

The topics covered include: relevant Directives and standards (such as EN ISO 14119 for interlocks);  a structured method of assessing changes made to existing machines (potentially but not always significant enough to warrant re-CE-marking); a practical example of a packaging line;  the application of relevant standards to pallet wrappers (such as EN 415-6 and EN ISO 13849) and the use of light curtains on the in- and out-feed; general technology developments in the field of functional safety on machines.

On the topic of interlocks, EN ISO 14119 has much guidance on how to prevent defeat, such as the use of coded interlocking devices, use of permanent fixings on actuators, location of the device and testing – which is covered in some detail. The much-awaited ISO/TR 24119 guides users on how to judge and avoid the phenomenon known as fault-masking on series connected interlocking devices – this is also explored. 

The question of whether a machine or process line needs to be CE-marked after changes have been made can be quite thorny, but the seminar presenter breaks it down into a series of questions such as: does the change introduce a new hazard or increase the risk associated with an existing hazard? Do existing measures mitigate it? Will the use of simple guards mitigate it? If controls have to be introduced or modified to mitigate it, what is the severity and frequency? Answering these questions help to determine if CE marking is required, always bearing in mind that maintaining safety is the priority, and CE marking is a by-product of following a systematic approach to that end.

A demonstration of how to use C-standards (such as EN 415-6) in conjunction with B-standards (such as EN ISO 13849-1) helps attendees to understand how to manage safety related controls on specific machine types (such as pallet wrappers), and guidance is given on how to reconcile some of the inconsistencies that appear between older C-standards and newer B-standards.
