laser marking and protection

[TECNOMODEL]

in the company we were delivered a laser marking machine that leaves me a bit puzzled.
the machine is of clear Chinese origin, despite the seller say that he chooses the components and assemblies, so much so that the operating system is also in Chinese.
the first thing that leaves me puzzled is that the work area is totally without protection, the only protection provided are a pair of glasses. Is this thing regular?
second aspect "strange", the machine does not have any indicative tag bearing model, manufacturer etc., even the indication of the network voltage to which the machine must be connected.
not to mention a mark there.
same question as above, is it adjusting such a machine?

Sorry, what did you buy? ?
on the level of protection for laser marking surely depends also on the class of laser used.
the laser markings for metals that happened to me to see all had lasers in class 4 (the most dangerous) and the machine had a total shielding of the working area, with windows to see the area with special glasses.
the drive command had to be given with both hands

His thing. they have bought I can't answer you, I found it in the workshop with the indication of starting to put it in production and I noticed these things.
I'm trying to figure out what kind of laser it is, hoping it's written somewhere.
Can you tell me something?

You bought a license plateless car and a circulation book. but above all without brakes. see what to do

What I would do, though, doesn't matter. who decides is someone else.

 

[pollo]

Nothing changes. the legal obligation is if new work equipment, then must comply with the specific applicable product directive. identifies the applicable directive, checks what it says and see if the equipment is compliant. is the first step of commissioning (also called acceptance testing)

 

[TECNOMODEL]

I found two plates on the laser generator

Meanwhile we have defined that it is a laser in class 4.

How can I know which directive applies?

 

[pollo]

on the website of the European community, look for the list of product directives (industry) and see those applicable

 

[pollo]

I forgot: being a assembly of several parts, the final manufacturer should have given you a statement together. in this statement lists the directives that it declares to have respected. depart from those

Thank you very much. I'll ask him a few questions.
by now that there are also this: as I said the computer is in Chinese, in my presence the seller installed what he said to be the language pack to make it work in Italian.
the next morning a lot of problems appear in the pc and the machine does not work, comes the seller who does a series of operations then tells me that he takes away the pc to clean it up. what he actually installed was an iso image (I don't know, I could say a castronate) and maybe there was some viruses.
I thought I'd take these machines in my cina and install a cracked so.
I don't know if you have certifications and anything.

in which section? I can't find where these documents are.

 

[pollo]

every little update the site (also how to get there)
here the pagehttps://ec.europa.eu/growth/select in legislation and standards and individuals the directive of interest

Here the link to find harmonized standards for the various directives (harmonised standards issued by the Community's mandate, whose respect is presumed to comply with the Directive)https://ec.europa.eu/growth/single-market/european-standards/harmonised-standards/obviously to be a machine must have at least one mobile organ not moved by human force: If your marker is just a steady laser, it is not machine
However you can search
Directive 2006 / 25 / EC of the European Parliament and of the Council of 5 April 2006 on the minimum safety and health requirements relating to exposure of workers to the risks arising from physical agents (artificial optical radiation).
or
Directive 2013/64/ue of the council

In short, the manufacturer in the statement reports the directives of which it declares compliance. In addition, depending on the equipment you may find various directives/regulations applicable: pressure (ped), machines (md), low voltage (lv), electromagnetic compatibility, atex, etc.

 

[TECNOMODEL]

Thank you very much, very kind.
I would say that already I can exclude the machine directive, the only movement present is on the column that brings the optics to focus, and it is done manually by rotating a flyer.

 

[pollo]

I should like to thank the rapporteur for his excellent report.
If it is a marker that shoots a radius only, if there is no movement do only a more or less deep point. I think your marking consists of writing something and so the radius will have to move: your manual movement is probably just for setting the zero.
If there is an internal movement, you will have mechanical risks (low magari), in addition to the fact that the control system of the movement has security functions (otherwise it would be like having a drunk rifle that shoots randomly) and therefore this command will have to comply with the essential requirements for its reliability (i.e. the manufacturer will have to ensure a certain minimum reliability that does what it has to do): If not, who assures you that does not write pippo rather than duck (functional reliability), or that does not shoot at a point outside the target (security reliability)?
are only two examples.
the absence of the indication of supply voltage is already a violation of the low voltage directive.
the absence of risk indications (although residual) is a violation of all past, present and future directives.
And so on.
the field is vast and that is why you have to have the manual (in Italian) and a declaration of conformity.

 

[TECNOMODEL]

the manual movement is in height to focus depending on the height of the piece.
the radius moves into a work area of 250x250 mm.
so the fact that the radius, and only that, moves determines that it is a machine?

 

[pollo]

I repeat, you have to see the directive.
I don't know the details of your equipment, so I need to be generic.
I'll only take you back Cousin the definition of a machine which gives Directive 2006/42/ce to Article 2.a)(a) 'machine':
— together equipped or intended to be equipped with a system of drive other than human or direct animal force, consisting of parts or components, of which at least one mobile, connected solidly to an application well determined,

other definitions, various exclusions, some exceptions. all in the directive and to understand it better there are then the guidelines issued by the community (reported always on the Internet page above) that explain in detail the various points of the directive. Finally there are the harmonized standards that tell you how to do to achieve compliance. This is what must be done by the manufacturer.
if you attend a consultant, in addition to that you will also have knowledge of the practice of field and the situation of Italian jurisprudence (in the end if someone hurts for that laser beam with prognosis greater than 40gg the pm must start the specific procedure of criminal nature).

 

[TECNOMODEL]

I thank you, as soon as I have some truce I begin to read the norm.
our case, however, is not that of those who must build/sold but we are the buyers.
I'm trying to figure out whether they sold us an irregular machine or not.
If it's the first case how you behave? and to what goes to meet a company that buys and uses n machinery not in norm?

the radius moves into a work area of 250x250 mm.
so the fact that the radius, and only that, moves determines that it is a machine?

the radius in any case must be protected, not only in the direction of issue but also in case any uncontrollable reflections, from which the need of complete sanding is born.

 

[pollo]

the employer, pursuant to Legislative Decree 81/08, art. 70, paragraph 1, must make available to workers work equipment in accordance with the specific laws and regulations of transposition of the Community directives of product.
sanction to the employer and the manager: stop from three to six months or fine from 3.071,27 to 7.862,44 euro [Article 87(2)(a)Your company's responsible spp knows this well, you tell him.

as you see, it is not only about the manufacturer (who remains responsible for the fact that he has supplied a machine that does not comply with the directive, in violation of national laws, and specifically of Legislative Decree 17/2010), but also the company that has given the workers an unconformed equipment: the sentence does not mean that the statement is enough, but it is the equipment that must be compliant (there are various judgments in which the employer has been recognized guilty for non-compliance of the machines). sometimes we talk about blatant and occult non-conformity: It is irrelevant and if you are here to talk about it, you have doubts, someone indicates that there must be this and this other protection (without specific references take with the springs all that we write to you, I understand), probably so occult is not and the conformity is strongly doubtful.

You're kidding. .
50 watts of laser are not a joke, considering that you risk blindness with 1 mw laser pointers... here you risk beyond the blindness assured also severe burns. .
If I were you, I'd refuse to put it in place, already the fact that I didn't have regular markings should have you ring a bell.
