Match the reference before relying on it
Start with asset identity, location, and configuration.
A reference is relevant only when its stated scope matches the asset and plant in question. Check the asset identifier, location, equipment family, configuration, and the reference's own scope. Similar-looking equipment is not proof that the same reference applies.
If an identifier is missing, a configuration differs, or the source scope is unclear, ask the local asset-information owner before treating the reference as applicable. Use the locally approved source for controlled or safety-sensitive instructions.
Illustrative asset-to-reference match
Fictional example for scope checking only; these are not real assets or controlled references.
| Example asset | Location | Configuration | Reference scope to verify |
|---|---|---|---|
| PKG-CV-204 | Northstar Plant East, Packaging Line 2 | Belt conveyor; changeover guide rail fitted | Confirm the source names this line and guide-rail configuration |
| PKG-CV-205 | Northstar Plant East, Packaging Line 3 | Belt conveyor; different guide-rail arrangement | Do not assume the Line 2 reference applies; check the local source |
Read the scope, not just the title
Family-level information
A family-level reference may describe common equipment characteristics, but it does not by itself establish applicability to a particular plant or configuration.
- Look for stated equipment-family limits.
- Check exclusions and configuration notes.
- Verify whether a local source takes precedence.
Plant- or configuration-specific information
A local or configuration-specific reference should identify the equipment or conditions it covers. If identifiers conflict or scope is absent, use the local document-owner handoff.
- Compare the asset identifier and location.
- Check revision or source information where available.
- Ask the local asset-information owner when the match is uncertain.
