The colour coded label ensure the operators in the area know exactly what their stack light alarms mean. This factory has no true andon system, all machines however have a stack lights indicating their status but with plenty of different colours etc. for various faults.
Ideally there should be standardization across all stack lights and failing that the above signage could be improved further by making it larger so it can be read from a distance in all directions.
In this example before the labeling there was just a handle with no explanation of what it was for and no one knew there was another one at the other side of the machine. A simple description solves this and helps ensure that backed up with training that the safety locks will be used in the right circumstances.
Clearly defined area's where bins must sit ensure that nothing else is likely to be left there and block the space unintendedly.
This shows a manual ball valve with a clear diagram beside showing that it should be closed for normal operations. This valve in the past before the label was fitted was opened by someone during production who assumed it had been close by mistake.This caused problems and down time with the process which is meant to run with just pure nitrogen from another seperate valve. It wasn't until the next morning when an experience technican came in that the problem was found.
There is literly thousands of ball valves in the factory so it is vital to know what state they should all be in.
