Accessafe has been commissioned by Carcano Antonio SPA to develop a safety plan for a new section of the plant, taking into account the existing section as well.
The risk analysis and the associated specifications drawn up by the manufacturer of the new component were provided to Accessafe’s engineers for the development of the layout, including the relevant access controls, in accordance with the PLr (as per UNI EN ISO 13849:2016).
Established in 1880, Carcano Antonio S.p.A. has steadily evolved facing the new challenges imposed by time pragmatically hence becoming a solid manufacturing company in the field of aluminium foil rolling and conversion coating. The company believes in constant technological and organizational development in its two production units based in neighbouring Mandello and Delebio which are run as a single unit thanks to their geographical proximity and to a continuous flow of information and experience in order to guarantee an ever-better specialization.
Indeed, the company’s production process is entirely integrated and traceable from raw materials to end-product as required by GMP, UNI EN ISO 9001:2008 and UNI EN ISO 14001:04 standards: an example of quality and efficiency to assure customer satisfaction and environment protection.
The layout of the safety guards was developed by Accessafe in accordance with the Machinery Directive 42/2006 and the relevant applicable regulations, following the Perimetra Functional Safety system for the turnkey safety implementation of the plant.
The order, which consisted of both the supply and mounting of the mechanical part and the supply of material, installation and cabling to the plant, was processed along with the scheduling of mechanic and electric technical staff intervention for a total of 8 working days from the material delivery date and for a total of three weeks from project acceptance.
Functional tests were carried out at the end of set-up in the presence of the plant manufacturer and Carcano technicians, followed by the handing over of all documentation relative to certifications, instruction and maintenance manuals and technical data sheets.
The executive project Functional Safety
The detailed design for Perimeter Functional Safety was developed in accordance with the block diagram characteristic of this innovative Accessafe service, which is also available to customers on a modular basis: Risk assessment and verification, and RES, Detailed design of the perimeter protection system, Supply of mechanical and electronic components, Installation and cabling, Functional testing, Training, Provision of technical documentation, Scheduled after-sales support.
Regulatory insight from Marco Vaccarone CMSE® Certified Machinery Safety Expert
Functional Safety Manager
During the review of the specifications resulting from the manufacturer’s risk analysis delivered to us for the evaluation and development of the securing project, I was able to collaborate with the engineers who had developed it because there was a risk consideration to the achievement of PLr that could have subjected the related certification to litigation. The required PL was equal to « d, » and to achieve it, an electro-lock with a latch system for mechanical failure exclusion was planned: guaranteeing this performance would have resulted in the manufacturer having to demonstrate that it had complied with the failure exclusion requirements of UNI EN ISO 13849-2:2013 (Table A.4) and that the maximum actuator engagement speed required by the device manufacturer would not be exceeded under any circumstances.
In view of this consideration, it was decided to modify the design by applying electro locks and sensors with transponder technology to ensure the achievement of PLr without fault exclusion.
