Hi all,
is there a standard our there which covers the recommended height and positioning of an emergency stop on a machine?
The below bullet points covers basic emergency stop expectations, but I was curious whether there was an actual standard (or detailed guidance document) out there on where the stops should be positioned?
Thank you
•Emergency stop buttons should be positioned within easy reach of the machine operator(s)
•They should be placed so their operation is simple and straightforward having regard to the limited response which could be expected in an panic / injured situation
•It should be possible to activate via another bodily part should the operators hands be trapped
•The posture of the operators normal working position should be considered (including the equipment layout) when positioning an emergency stop
•The activation of the emergency stop should not create additional risks, such as stopping fume extraction.

Knee jerk answer.
Try the machine product standard as a starting point?
What machine is it?
I'll check some of the guidance I have when I get a chance.
Remind me by PM if you like if I forget, I can't do it right now.

Guru, I don't know about standards but anyone doing a risk assessment who has any competence at all should be able to understand the correct positioning of the dirrerent types of emergency stops.
This is where assessment reviews are important when there is a change of risk, or operator or anything else.

Guru,
I have had a few minutes to check a few things, but, I have to pop back to real work again shortly!
Is this for retrofits, i.e. PUWER compliance, or are you looking at this wrt new machinery "pass off", or design of new equipment?
IF, it's PUWER98, then a cheat is to look at newer machinery of the same type and see where the e-stops are fitted by the manufacturer! ;)
There are a few A & B type standards you could look at, I'm not sure which will apply, nor which will actually have the information you need, sorry, they are:
ISO 9355-1 & -3
EN 60204-1 (But, I don’t think there is much in there with respect to positioning of e-stops above the bullet points you already have)
EN 614-1 & -2
EN 894-1 & -2
EN 1005-4
EN 11064
EN 547 series
EN ISO 14378
EN ISO 15537
EN ISO 15536-1
EN ISO 3411
EN ISO 6682
Then you would be looking to the "C-Type" standards for the machinery, or perhaps go to the machinery manufacturers association, the PPMA, I know have a consultant who specialises in such things they work with.

Thanks Roundtuit. Quite important to have emergency stops on lifts, but suprised that OTIS (other suppliers are available) found it necessary to elevate this particular thread.

Ha Ha Otis, elevate, good one. Emergency stops on lifts would be a great idea in multi story tower blocks, giving the local yobs another game to play and the FRS an even busier time.

firesafety, for the avoidance of doubt I was thinking of an emergency stop located in a position where the vandals CANNOT easily access it!!

Don't you have to look at the machine and the ergomonics ?
The Stops need to be in a position where anyone operating the machine can operate them, by hand, knee or foot etc, so even if the manufacturers supply the machine with them fitted, you need to look at the machine and ensure any operator can operate the stops, (eg - if you have a wheelchair user operating a machine the switch would likely need to be lower) etc etc

The thread had died a natural death in 2015 before being resurected by a spammer Otis123 - this name play led to humour given the name is not too dissimilar to that of a lift (elevator) manufacturer

For the avoidance of doubt all emergency stops have to be easily accessed. How can you seperate vandals from normal users.
