Drawings, job packets and paper
Drawings, job packets and paper. What the requirement says, what it means in practice, and what an assessor will ask.

The oversight
Media protection covers paper
Most programmes treat this as a question about systems and forget that the requirements on media apply to physical media as well as digital. A printed drawing carrying controlled information is covered information on a sheet of paper.
On a shop floor there is a great deal of paper, it moves around, and almost nobody has thought about it.
Where it is
Six places to look
- Job packets and travellers, printed at the start of a run.
- Drawings taped to machines or pinned above benches.
- Inspection reports and first-article documentation.
- Setup sheets and tooling lists derived from the drawing.
- Whiteboards with dimensions written on them.
- The recycling bin.
The last is the one that produces the clearest finding, because a skip of drawings behind the building is a control failure anybody can see.
Marking
The marking travels with the sheet
Where information arrives marked, the marking is part of it, and derived documents carrying the same information generally need the same treatment. A setup sheet transcribing controlled dimensions is not uncontrolled because somebody retyped it.
This is the point most often missed on a floor: the protection attaches to the information, not to the original document.
Handling
Four practical arrangements
Print only what is needed, when it is needed. A packet printed for the run and destroyed at the end is a smaller problem than one that lives in a folder.
Store it somewhere with a lock. Physical protection requirements are met by ordinary means: a cabinet, a controlled area, a sign-out sheet.
Destroy it properly. Cross-cut shredding or a contracted destruction service with a certificate. The certificate is the evidence.
Account for it. Where a document is issued to the floor and not returned, somebody should notice.
Visitors and walkways
What is visible from where
Drawings on a bench beside a route visitors take, or a screen facing a window, are disclosures without a system involved. This is a floor plan question and it is answered by walking the visitor route and looking at what a stranger would see.
Most suppliers doing this find two or three things and fix them the same afternoon.
Screens count too
The terminal at the machine
A controller displaying a controlled program is displaying controlled information. Positioning, timeouts and who can walk up to it are the same considerations as for paper, and they cost nothing to address.
Evidence
What to be able to show
A procedure covering printing, storage, marking and destruction. The destruction certificates. The sign-out records if you use them. And somebody who can explain the arrangement to an assessor without consulting the procedure.
The last is the test that matters, because a procedure nobody on the floor can describe is a document rather than a control.
The media protection and physical protection families of the NIST publication, which apply to media in both digital and physical form and to the areas where information is handled.
The control text is published and states what applies to physical media directly.
Who handles it
The people who print are not the people who wrote the policy
Job packets are produced by planners and printed by supervisors. Neither typically attends a compliance briefing, and both make daily decisions about what gets printed and what happens to it afterwards.
Ten minutes with them is worth more than a procedure, and it is the conversation that establishes whether the arrangement can work at all.
Photographs
The phone on the floor
Operators photograph setups, defects and drawings routinely, for entirely good reasons: to show a colleague, to record a problem, to remember a fixture. Those photographs are copies and they sit on personal devices.
The answer is rarely a ban, which fails as reliably as the removable media ban. It is providing a sanctioned way to capture and share images that is as quick as the phone.
A morning that pays
Walk the floor with a bag
Collect every sheet carrying controlled information that is not where it should be. The pile is the finding, it is undeniable, and it makes the case for the arrangement better than any policy draft.
