Identification of Raw Material being used In-Process

Wondering if I could get some opinions on this.

Here is the scenario:

Saw operator cutting a pile of steel piping.
Operator gets the steel from an unlabeled stack of "stock" material. Stock material is stacked alll over the shop unidentified due to the nature of the material just being considered as "stock". There is steel piping, structural steel beams (small ones for building small steel frames) and flat stock steel bars, all in the same state, nothing labeled.

Asked the saw operator how he knows he is using the right material, he states "becasue I measured it compaired with my BOM". Which he did, and this is how everyone does it.

I wrote up a finding for idenification initially and then had a discussion with management. They said there is no way to control part numebrs or ID on stock because it comes in in large bundles, which I could understand. So they store it where they can find room after its recieved in and then it is just unlabeld "stock" after that. All sizes and shapes are handled this way. and after they cut pieces off of it they dont mark the leftovers, just put it back into stock. But they are meausring it before using it for cutting or welding. And to be honest we have not had any problems with people using the wrong size material due to this that I have seen since I have been here (year).

After the operator cuts it he labels his pallet with a JOB# and ID which was all good.
We have no tracebility requirements for 99% of the stuff we make (its non auotomotive) and the 1% we do, we have an entire seperate process for, its a whole other standard we have to meet.

Think GIANT job shop environment on a grand scale and you will kind of get the idea of how we are.


Just wondering if we are going to be ok like this or are we on a slippery slope?

Is all the material the same 'type'? For example is it all 4140 or 17-4 stainless. It is all structural steel but do you have different alloys of the structural steel?

Another place this could come under scrutiny is: What happens if X material is found to be non-conforming? Do you have a method of recalling everything this particular material has been used on? If not, I believe you would have to recall everything that it could have ever been used on.

I will be the first to say I do not know that much about structural steels so this may not even be an issue.


:topic:
The method we use of tracking material is based on the purchase order. When material is brought in from a PO we assign a unique receiver number (that ties back to the PO). The material is tagged with this receiver number and we can find all jobs that ran this material (we are Aerospace and Commercial so material handling is important per our customers).

The ISO standard says "Where traceability is a requirement...."- management need to defend that it is not a requirement.

If you have no traceability requirement from a customer or regulatory standpoint, then I don't see an issue. But you should have documented somewhere a rationale for that decision.

This is 2015. Identification and traceability are possible in almost, if not all, situations. It may not be an issue now, but in the future not having any system could come back and bite your company in a big way.

At the very least, I would push to get a good identification and traceability system designed and put into place. :2cents:

If it is the same type of material then there is less of a concern. If you decide you want to identify different material typed, just color code the ends. I'll bet your incoming already has the color coding.
