comment to our response:
One thing: The system consists of a furnace that burns waste and generates steam by means of another "machine" which is then sent to a turbine that generates electricity. The fumes sent to a filter system and then to slaughter (this in a nutshell) ... the parties each have their own clearly defined purpose: in this case should not have different sets of machines? Each individual would work in reality (the oven and could do so without burning waste heat recovery, the turbine uses steam generated from heat recovery, but may well take it elsewhere, killing the plant id - beyond that it would be illegal - I could not have it and the machine would work, however, etc.).
Certificare tutto l'impianto, per fare un parallelo con le chimiche, sarebbe come dire che tutto l'impianto chimico (dai serbatoi di stoccaggio dei solventi fino al post combustore) è un'unica macchina. Che francamente mi sembra eccessivo.
nostra risposta:
Per cautelare le persone devi garantire un funzionamento sicuro dell’insieme. E la UNI EN 13849 vale proprio per il quadro di comando e tutte le sicurezze interconnesse (quale SIL necessario?).
Puoi certificare ogni singola macchina, ma per venderla da sola, isolatamente. Ma per l’insieme funzionante devi verificare la conformità ai RESS dell’insieme. Attenzione anche a PED e Atex (area già classificata?), After specifying that you do below.
to exclude the need to prove. Anyway, to assess the risk of explosion etc. for excluding them. If you need
schemino you attach a standard that we use internally, for 2006/42, on how to proceed in an orderly manner, but that also applies to the other in principle. It is clear that for you is even more so the combination of hazards. "
And then look at the material from our site on the simultaneous application of several directives: direttive_simultanee
