Suitable hygiene in the manufacture of machinery: an option or an obligation?

The directive 2006/42/EC forces to the manufacturers of machinery and systems to ensure that his equipment do not represent any risk for the people. This requires that they take measured to warn accidents. The evaluation of systematic risks taking an important paper in this subject.

The certification by means of the application of the standards increases notoriously the legal hygiene regarding the fulfillment of the directive of machines and allows to have proofs in case of his request in a trial. In any case, this does not free to the individual of his responsibilities. After all, the standards have some tolerance when they evaluate the risks or schedule and implement the functions of hygiene. Even the standards for the products specified Type C do not dictate of clear form the rules to be followed for all and each one of the situations.

A solution of hygiene of success has to also warn that the functions of hygiene are tricked. Of what serves to have a good door of hygiene if the operario can simply trepar by her? This does not put only in risk to injure people or damage the own machine, comports besides financial consequences. An accident can cause a long unemployed in the production and a negative advertising that it can damage the image of the company. In the worst of the cases, the company can finish happening years struggling in legal battles.

Some companies see the measures of hygiene like a necessary evil that does not do more than giving complications and increase costs. Increasingly manufacturers of machinery and systems begin to recognise the competitive advantages that they can win through a solution of modern hygiene: the solutions of integrated cheese cheese hygiene, with an improved location of errors and diagnostic, can reduce the ratio of failures and allow to the productive process a new flexible design.

Often the technology of hygiene has the deceptive reputation to be a conservative subject. This nourishes of the experiences of the users that have discovered some practices that over time show his efficiency. The technology of hygiene uses rules and technical that derive of the feedback of the user to define the requirements of the technology of hygiene of high quality. This is one of the reasons of because the technical advances appear later in this area that in the conventional automation.

At the beginning, for example, the relays of hygiene were used to implement functions of individual hygiene such as the switches of stop of emergency. However, to measure that happens the time, the requirements in the automation, in the protection of the personnel and in the functions of hygiene have gone increasing. Consistently, a new fan of components more powerful, flexible and adaptable have substituted to the relay of hygiene.

Now, the controllers of hygiene are to the avant-garde, mainly because the increase of the degree of automation of the machinery requires of flexible connections between the different functions of individual hygiene.

In this case, helps to evaluate the conclusions obtained already existent, like the guide VDMA on the use of technology of programmable hygiene in the field of the mechanical engineering. Like result of the narrow cooperation between the manufacturers of machinery and systems and the providers of components and solutions of automation, obtains in a big variety of approaches and experiences of success that can help to identify and delete risks. The directors and responsible in the electrical fields and mechanics have to be able to evaluate the technology of hygiene, take decisions and do what is necessary to put in practice a technical solution. Nowadays, the companies can not allow the luxury of prescindir of the technology of programmable hygiene. However, the development of software of hygiene involves long of development and a high investment having afterwards a relatively low performance. Thus, from a perspective of costs, a solution of hygiene with a standard and open communication is the optimum answer.
