I am confused! Our technical dept. have just bought a big new copy router which is is to all intent and purpose a woodworking machine (although we only machine plastic with it). They made an assumption when buying it that because it was CE marked and had a certificate of conformity it would be safe to use straight off the pallet (I know we would have to do a local RA etc., but you get what I mean). I have looked at it however and upset them greatly by telling them it certainly isn't safe. It has a two handed operation on the lower cutter, but the two buttons can be easily operated with a single hand, leaving the other hand free to touch the rotating cutter (which is unguarded except for a small debris deflection screen). Both sets of 'two button' operation can be easily defeated by taping one button down (there is no timed safety circuit to prevent this). Also it does not have a braked motor on either cutter (the rotating bit does stop within 10 secs, but there is no actual brake on the motor nor is any other electronic braking device fitted - we are worried that over time, as it ages it will not stop so quickly). Lastly, the control levers for the upper cutter are so high off the ground that the majority of our guys would have to stand on tippy toes to reach them (they are not inherently adjustable either - the levers that is, not our guys....). This machine is from a well know european manufacturer and supplied via an equally well known machinery supplier in the UK. So the million dollar question is - what has gone wrong here? Am I misunderstanding the regulations and associated safety requirements, or have they supplied something unfit for purpose? If the latter, how did it manage to get a certificate of conformity? I am taking quite a lot of flak from certain elements of the management who think I am wrong in my assessment and we should just rely on the guys to not try to overcome it (and I am not too big to admit it if I am!!), so if there are any machinery safety gurus out there I would love to know if anyone has experienced this before and If I am being over zealous! In the meantime incidentally, we have locked it off and will not use it until we get the supplier in for a discussion. If necesary we can modify it ourselves in-house, but that seems a little ridiculous for a brand new machine. Stu

One answer could be (and there will be other responses) that they have CE marked it and made a declaration of conformity against certain standards but not others. The devil may well be in the detail. They could have issued a certificate of conformity for, say, electromagnetic testing and ignored a lot of other things more pertinent. Thats why its important that you do your PUWER assessment to find the things you have - well done.

There are a lot of ifs and buts here but it does sound like they have CE marked this piece of kit and issued the certification themselves, which they are perfectly entitled to do. The should be a technical file with the equipment which will list the harmonised standards against which the the equipment was judged to have conformed.

As already stated; the devil will be in the detail. You have done the right thing by (a) not using it and (b) getting the supplier/manufacturer in. Have a good look at the Declaration of Conformity (DoC) and see what Directives and Standards it states the machine is CE marked against. Then when the supplier/manufacturer turns up ask them to state how the Essential Health and Safety Requirements have been met. (For certain types of woodworking machines then the company who produced it may have had to use a Notified Body (testing house) when CE marking the machine; and not simply self Certified it, so that may be worth looking into as well). If the supplier/manufacturer just tries to brush your concerns off, you can of course always state that you intend to report this matter to the relevant enforcing body as they can demand to see the Technical File the manufacturer will have with regards to CE marking. With regards to two handed controls, you state that they can both be operated by one hand, whilst I’m not a machinery expert this sounds wrong as I would have thought that they should normally be spaced far enough apart to ensure that this cannot happen. You also state that can be easily defeated by taping one of them down, this also sounds wrong, (again Im no expert) but I would have thought that they should not be the type of switches that can be bypassed by simply taping one switch closed. We have in the past built in house equipment and in once instance had to use a two two handed control; and we ensured that the switches were of the type that required both switches being depressed within about 0.5 seconds of each other for the machine to operate. (BS EN 574 covers this type of control, but as you are probably aware BS's are not law). My advice…………..see how the meeting goes, then if necessary kick up a stink and mention passing details onto the relevant enforcing body and you may find that they suddenly become happy to foot the bill for making the kit safe. You may want to try to get your company to involve you more in the purchasing of new machinery at an early stage, as this can help in avoiding this type of headache.

I agree with Smitch. Check the D of C to see what standards have been applied. Remember though that if it is built to a harmonised standard the manufacturer is entitled to CE mark and declare conformity. That does not mean that it is safe enough for your environment. I've felt for a long time that the harmonised standards are often just descriptions of machines that exist, and sometimes aren't stringent enough to ensure safety. Certainly the type of 2-hand control you describe does not comply with BS EN 60204-1 "Electrical equipment of machines". The stopping time doesn't seem to be a problem - if there's no brake, why should it take longer to stop as it ages? How often do the upper control levers need to be accessed? PM me if I can help further - I'm not a consultant, but work with machinery safety standards.
