Today, an Operational Manual for a CE-marked plant must include a description of all residual risks from the assembly to the disassembly phase and how to protect against these risks.
Before the machines directive in Europe, particularly when used plants were purchased and original manual missed, buyers sometimes, not always, this depended on the size of the company, wrote safety work instructions for safe use of the plant, without having the expertise to write them.
But today in Europe a plant cannot be sold and used unless it has been marked Ce And equipped with all the necessary safety requirements including safety instructions relating to residual risks and the precautions to be taken.
I believe rather that the ignorance of the management of the company and the competent bodies in relation to the Machines Directive is enormous and someone, probably ignorant in this matter also, takes advantage of it.
Generally I see this, perfectly drafted manuals remain in the drawers of department managers or in the archives of technical offices. While consultants without reading these manuals and having a deep knowledge of the plants as only can the builders prepare the instructions.
Not to mention the competence of external trainers, it is better to avoid talking about the subject
