Good Morning Colleagues


I am currently trying to find information on current guarding standards for automatic routing machines

Has anyone any experience of the make Gerbre sabre?


Many thanks in anticipation

Stuart,

Specifically what does your question relate to? There is the manufacturer's RA which determines their CE marking procedure, in the UK he is the Supply of Machinery Reg's etc.

Hi Mitch


Just general on guarding

ie Is there a particular practicable standard accepted by industry / HSE or is there a EN C Standard for this type of machine


The CE mark is displayed ( For what use that is)and I am trying to get hold of the declaration of conformity

My concern on guarding was that the machine was set and operated remotely from a control panel but when in motion is was possible to approach the danger zone

I am looking for some authoritative standards to backup my argument

Cheers

Stuart,

As far as I am aware there will is no standard that will specify how to guard this machine but there is a series of BS EN's which specify what you should consider when considering or designing machinery guarding I will email you direct and it contains details on an excellent supplier of supplementary guarding. I used to own a water jet cutting machine which was remotely programmed and operated, this had a light guard fence around the cutting bed so that operators could not access it whilst the machine was in operation, the machine was manufactured in the USA and was not supplied with this type of guarding there only in the EU. As regards the declaration I have come across this 'reluctance' to provide one with suppliers before and a veiled threat to contact the HSE normally brings this to a satisfactory conclusion.

Regards

Mitch

There is no definitive standard of guarding. It is back to first principles ie, can you access the danger zone, if so then (wherever reasonably practicable) you must provide guarding. But that guarding could be any type appropriate to the work (fixed, distance, interlock, pressure mats, light-guarding etc) as long as it cannot be easily defeated or cause an additional danger.

In my experience CE marking means nothing! A requirement it may be but it still doesn't get out of the requirements of PUWER.

Be careful regulation 11 is actually a practicable duty not a sfrp one with regarsd to dangerous parts. This derives both from the Directive and previous Factories Act and OSRP requirements. There has not been any direct case law on this point and most texts refer to pre PUWER decisions.

Claire,

Agree somewhat on your perception of CE marking though speaking as someone who until my current position bought machinery and now supply machinery it means what you make of it either in what you demand and expect of your supplier and on the other hand what you feel you should provide as a supplier. Unfortunately all too many suppliers play on peoples ignorance of CE marking requirements which belittles the intent and purpose of them.

Bob,

In theory guarding is absolute. But, for example, the dangerous parts of a radial arm drill can't be guarded and so it is industry accepted best practice to use an aerial trip that merely prevents significant injury rather thn preventing contact with the dangerous part. There are other examples where two handed controls may be considered adequate and woodworking machines are a case in point where guarding of the dangerous part is often not possible and so partal guarding, safe working practice and training are considered sufficient.

Dangerous parts do have to be guarded but the level of guarding will vary and that is why it important to RA the activity and decide on the most appropriate form of guarding, taking into account industry best practice.

Thanks for the responses so far

Anyone out there ?

I dont believe there are standards for guarding on remote operated routing machines,This requires you to devise one..
Fixed, interlocking, trip or adjustable. If you have employees able to walk to and enter an area of open machinery, you should make immediate plans to prevent this.A simple mesh fence system would be a good start.

Stuart,

We are not giving you anything more specific because that's what we are saying, there is no regulated guarding set-up for automated routers.

Short of seeing the machine and watching what work people are doing all we can say is that you need to assess it in accordance with the requirements of PUWER.

In general for automatic routers you would be looking at keeping operatives away from the danger area. This varies from machine to machine but is often through the use of light-guards that trip out when the danger zone is entered. But it really does depend on the design of the machine and so you are asking us to give advice blind.

Can't

Dear Claire


You are somewhat missing my point

Please don't patronise me

I was merely asking fellow practitioners whether there was any specific guidance / standards on automatic routing machines.

I am not seeking a regurgitation of the PUWER regs which you personally don't seem to really understand considering your earlier reference to reasonable practicabilty !

This is a professional forum that I have used before and had some excellent inputs at the right level

Please treat it as such

You were repeatedly told that there are no standards yet still kept asking for more specific advice. I reinforced what was said and gave you some tips on specific guarding solutions. Since when was giving advice upon request patronising.

As someone who has successfully stood up and prosecuted breaches of PUWER on numerous occasions you have a damn nerve telling me I don't understand the requirements of PUWER. I also have a great deal of experience with woodworking machines.

Try looking at Reg 11 Section (2) and I think you will see the term 'practicable' used several times.

I shall ensure I never respond to your request for advice again as you are obviously incapable of accepting it prefering instead to insult another's competence.

I think this is what you are looking for.
I have experienced Gerbre sabre machines.

My general experience o similar machines would be to look at teh inter-relationship between the guarding requirements and the noise suppression requirements. It is practicable to achieve both adequate guarding and noise reduction to below the 80 DbA action level and in my view, as this is an automatic machine you should endeavour to do this.

The real issue will be the feed arrangements but I suspect this is a fairly large scale process to require such equipment and process efficiency, therefore, will be enhanced.

This is exactly what I was looking for

I always try to research myself before coming on this forum but sometimes draw a blank

I wouldnt mind having a chat RE the Gerber Sabre machines as I have tried the manufacturer etc and drawn a blank


Many thanks

Thanks Bob

You make a good point RE Guarding and Noise reduction and I will certainly take this into consideration

Stuart,

Is this a new installation or a situation that has arisen from an RA? The supplier ('whoever placed the equipment on the market'-I think!) does have some legal obligation to co-operate and provide information to the user of the equipment.
