how can i not cut my finger?

[Fulvio Romano]

I have the following situation in a car. a 50mm high opening inside which there is a circular saw (tranquilli, before putting the hand I removed the current).
I can't reduce the opening, so I have to move that yellow thing to keep me away. If I apply the uni en iso 13857, then something strange happens. I can't stick my hand, so I'd just move the protection to about 200mm from the cutting line. the standard instead jumps from 120mm directly to 900mm (because or only the finger passes, or I can stick the arm). possible that there is nothing intermediate?
also how can the same table be applied to a child of 3 years and to an adult man? Is there a way to say "Add a row that at 50mm is good a distance of 200mm"?

apart, I would leave a nice space, more or less following the norm.
the operator may have the arm of a child (it is not to be excluded).

the premise is that the norms published in voluntarily but give the presumption of conformity to the covered res.
children cannot use that machine (normally you write it in the manual) but there are exiled, small people. is that the norm clearly says it but the manufacturer in this case could prove that that the machine will not be used by children (the machines can also be used by children? normally not, but reasonably is possible).
that hand of the photo doesn't reach the dangerous organ but you can't know if who will use it will have a "small" hand or not. the norm was written on the basis of anthropometric norms and therefore, to date, is the state of art. means that there are people who have arm size so small that they can insert it on 30 mm slots (and even less).
the solution is the derogation normally but you must demonstrate that that solution is equivalent or better than the norm itself. It's not easy!
Hi.

for the attainment of danger through openings, the norm distinguishes between people over 14 years and children from 3 years up (of course the latter for public places) in which the smallest dimensions of the arts are taken into account.vedi tab. 4 e tab. 5 a questo link.

Is there a way to say "Add a row that at 50mm is good a distance of 200mm"?

look if you can be useful these indications (pdf) relative to the safety of the hand provided by the modena ausl.

interesting. I have the version of the 2008 rule that does not distinguish for 3 and14 years. the version of 2020 (the last) instead yes.

you could put a sensitive security board that stops immediately when you approach.

It's a little complicated, and it shouldn't be like that.
the machine is certified c, so for the manufacturer it is okay like this. However, this risk is not mitigated. the intervention therefore cannot be too invasive on the machine because it must be done by a subject not enabled as a manufacturer. also has a rotating blade, so it is attached iv.

It is clearly not what you are looking for, it does not solve the normative dilemma, but, only for informational reasons if you do not know it already watch this video. safety blade
