Maintenance Scope

It means your instructor / lecturer does not know much about instrumentation or maintenance or both.

Although it is often difficult to understand the (strange) language of the instruction manual of a previous model.

Gray areas are created by people. It is not inherent in the job.

In my case, our electrical-instrumentation section is in charge of pneumatics and hydraulics in addition to the electrical and instrumentation equipment. I wondered about this when I joined the company because, traditionally, pneumatics and hydraulics were the mechanic's domain. I was told that it had been that way since the beginning and no one was willing to change it.

That was not the gray area.

The gray area came about when people started asking "who's in charge of the equipment that are connected to the pneumatics and hydraulics?" The mechanic's contention was that, since the device (say, a valve or a diverter) was connected to the pneumatic or hydraulic cylinder, it was the instrumentation's responsibility. Our section argued that a valve was a mechanical device so had to be taken care of by the mechanics. What happened was that no one wanted to touch it because "it's the other guy's responsibility". That's a gray area.

Another one in the installation of motors. As electricians, we connected or disconnected the motor's cables. Mechanics argued that dismounting and mounting the motor were our responsibility. The counter argument was that, since electricians and instrument technicians had small tools, mechanics had to do the mounting and dismounting. That's another gray area.

We eventually resolved these issues over time but it did cause some friction between the mechanics and the electricians and the anger of the production people (who's going to fix this thing!?).

My advice is to sit down and talk who's responsible for what. Make it clear and get everyone's agreement (and I mean everyone). The production people should also know so that they will call the right person for the job.

Personally, I'd prefer that both the electricians and mechanics help rather than point at each other. Pointing doesn't get the job done.

hi vulcan

you are right .your answer indicates that you are experience in maintenance

I have faced all of these situations in some places you talk like you were me

I want to add that a lot of these problems appears when problem happen or break down or shutdown even if the work is segregated

every discipline says that he is innocent and its equipment is working very well and accurate and the problem in other department whose people did not do the correct action and so on

best regards

Grey areas are those not covered by written procedures.

The manager of a particular area is usually responsible for writing and maintaining procedures for staff to follow. Grey areas need to be referred upwards for action so that procedures can be expanded to encompass the issue.
