Just a quick questions folks. Should grinding equipment be fitted with an E-Stop? I have read PUWER and it as we know it states were appropriate to have one fitted to work equipment and based on risk assessment. This is a new piece of equipment and am just wondering if anyone has an E-Stop for bench grinders as good practice? Any suggestions would be appreciated.
Cheers, Gav

Gavin,
If the equipment has been manufactured in accordance with EN 13218 Machine tools - Safety - Stationary grinding machines, then I would say yes, an emergency stop is required. In EN 13218 there are also a number of other requirements regarding the reliability of e-stops under certain conditions. Do you have the Manufacturer’s Declaration? EN 13218 should be listed in the declaration if the equipment has the CE mark.

Sorry to hijack the thread but what if the grinder or equipment in general is 40/50 years old and has no e stop fitted but has the on/off buttons within easy reach of the operator?

Tom,
Thanks for the reply. I don't have access to that EN 13218 to fully read into it but does that apply to any type of stationary grinder? Ours are pretty standard equipment. I'm contacting the manufacturer to ask the question as i can't find any reference to it in the Declaration of conformity for either grinder.
As metal man has said on this posting a isolating on/off switch is available and readily accessible to operator on these machines so on the risk assessment i don't think there will be a need for E-Stop but obviously want to know why this equipt isn't listed with you EN you mentioned.
Cheers again.

Gavin,
I am not sure what type of grinder you have but if it is stationary, uses and abrasive product, and is listed in table 1 of EN 13218 the "Emergency stop devices shall be easily accessible and provided at all operating positions". (EN13218)
As for the on/off switch; provided the components and operating characteristics meet the applicable requirements of EN 60204-1 Safety of machinery –Electrical equipment of machines, and EN 418 Emergency stop equipment, functional aspects you should be fine. (this condition is not likely)
This part could be interesting and I am very interested in hearing from others. In Europe, are emergency stop buttons considered to be protective measures that are intended to protect people from harm?
Cheers
