You could also take a look at EN 1088:1995+A2:2008 Safety of machinery -
Interlocking devices associated with guards - Principles for design and
selection (Harmonised) and EN1050 - the basic machinery risk assessment
standard (not a lot of use, but it might help)
This might also help: http://www.machinebuilding.net/ta/t0178.htm
(1st to come up in a Yahoo search on EN1088)
BTW most modern Machinery Directive Harmonised Stds include a relevant risk
assessment matrix with the important points listed.

Derek,
You might check EN 61508 and whatever ISO standard is referenced for Risk
Assessment. My guess is it will depend on the risk and the severity of that
risk that you are trying to avoid.

Subject: [PSES] Light curtains
Hi All,
I'm faced with helping a friend work through an OSHA finding that requires
the fitting of light curtains on several machines in a metal fab shop.
Several of these machines were never designed to have light curtains, but
OSHA wants them.
So... Can anyone point me to resources specifically regarding what the
machine should do if the light curtain is activated by a hand etc. Is
terminating power to anything making movement happen sufficient?
I hope this is not off the list topic list.
Thanks,
Derek Walton
