Hi I am wondering if someone with machinery knowledge can help me please? We have 5 lathes, very old. A couple have lathe shields and the others have chuck guards. The chuck guards are not fit for purpose (too small for all applications) and the lathe screens are always pushed to the side, unless the operator uses them to protect against the splashes from the fluids. My question is the following; * what standards do the chuck guards need to meet? * do the lathe screen need to be interlocked? I am currently making recommendations on bringing the machinery up to date and compliant but I am struggling ! Can anyone offer advice? We also have a milling machine - I have been told that if this is guarded it cannot be used!! any help here would be appreciated also! it currently has no guarding at all. All help appreciated! :-) Thank you

Hi Sounds like you need to get some one in who is competent in this area - they will need to assess the machines, which can't properly be done on a forum like this. Check out the IOSH register of consultants. Also, you may wish to get trained. The HSL run courses. http://www.hsl.gov.uk/he.../machinery-safety-series Ian

Of British Standards publication PD5304 or http://www.machinesafety...ews/nelsa-machine-guards Look under the 'nelsa' web page

Hi Thanks for the feedback. I have recently been looking at the course at the HSL, I think this will help me in this area. I have conducted the risk assessment and a PUWER assessment and identified that we need guarding - I was just wanting help and advice from someone that has installed guarding on these machines as I am being told that the machines can not be used with them. I know they can but I was wanting the best solutions along with some evidence to back up my thinking. I will take a look at the British standard. thanks again for the feedback, I really appreciate it. :-)

Not the usual old story... machine can't be used with guards. If you understand the term 'practicable' as applied to machine guarding, you will see that the argument has little merit. If it can be shown that guarding can be used, as per the examples shown - then you are very unlikely to win a legal argument if you had an accident and the HSE prosecuted your company. Standard machine tools have well recognised ways to provide an adequate level of guarding and also allows them to be used.

My main customer has an old milling machine. I advised them some years ago to fit an adjustable interlocked guard, something like this one, http://www.clearmachines...ort%20mill_thumb_256.JPG Yes, there was an excuse not to: can't do the work/jobs Then last year an HSE inspector issued an Improvement Order (discussed on another thread) Interlocked guard was purchased and fitted. Actually I wasn't completely satisfied with its effectiveness as it doesn't provide 360deg protection, but anyway the inspector was happy As for the 'tricky jobs', not once have the fitters had to remove the guard to do a job. Drilling holes in bulky items, they just found another safe way to do it.

There are British Standards for machine guarding which the HSE use in court to prove inadequacy. I attended a HSE talk of this subject a number of years ago and the one thing I remember the most is that you need to ensure compliance with these standards. They are very instructive.

Thank you all. Does anybody have a copy of the British Standard relating to guarding? Thanks again

Sorry Garratt39306, they are about £90 each but you need to find out which one you need. If I got a copy of the presentation I will PM you.

Hi They are so expensive. As mentioned above by Ian Bell - the standard I am looking for is PD 5304:2014 Guidance on safe use of machinery. Thank you

PD 5304, is the document that gives good guidance, it's no longer considered a British Standard though, it is a Published Document, hence the PD bit. It is copyright thiugh still. If you need then perhaps the company should buy it? You should be able to get read only access at your local public library I suspect. If you have specific questions then perhaps specific points can be provided.

You don't need t buy PD5304. Assuming we are talking just 'bog standard' machine tools - just follow the link I posted to a specialist company - they well send a sales rep out and advise you accordingly what type of guard your require. As previous, no excuse for not providing adequate guards for normal machine tools. Any excuse that the machine can't be used is just rubbish.

Yes Ian, but, and there is always a but, "off the shelf" guards may well limit the range of application of the machine to less than it was originally designed to cater for. The greater "range" may well be able to be accommodated, however, safely and guarded adequately, however that may well require more than a single set of guards. I do however, fully agree that it can be done, it just needs some thought. Oh and Procter guards do know their stuff, and Jeremy was quite a Gentleman when I met him. I suppose in the spirit of the forum, I should say that other guarding suppliers are available. You pays your money and you takes your choice. Remembering it is your company that is "signing" the PUWER assessment...

Hence why it would be a good idea to speak to a sales rep from a specialist guarding company - so the correct guard is purchased. Again, the machines are standard machine tools - for lathes it will depend on the chuck size. Milling machine - usually the guards are fitted on to the table of the milling machine. Pedestal drill - spindle/chuck guard

Thank you for the feedback. I have emailed pictures of the machines to a guy at Proctor / Nelsa and I am waiting for him to get back to me. Thank you all again, have a fab weekend!
