Regarding emergency pullcords/wires on powered machinery:
I mean the type that is used to trigger an emergency stop on a machine if the operator pulls it, or steps on it.
(The cord/wire runs horizontally between the normally closed switch that it operates, on one side of the machine to a fixed 'eyelet' point at the other end of the machine)
Should the cord/wire be of a specific colour ?
TIA,
