Check whether the reference fits the work
The approved source—not this page—governs technical work.
Use an approved technical reference only when its equipment identity, scope, and applicability match the work context. This page explains how to check a reference; it is not itself a controlled procedure.
For regulated, safety-critical, or sensitive work, use the applicable domain-owner-approved material for the relevant role and location. If the source is missing, its scope is unclear, or two sources conflict, stop relying on the disputed detail and request clarification from the responsible domain owner or technical support role.
Four checks before relying on a reference
Record what you checked so a colleague can follow the reasoning.
Equipment identity
Compare the identifier in the work request with the identifier named by the reference. A similar model or nearby asset is not enough to establish a match.
- Write down both identifiers when they differ.
- Do not silently normalize a mismatch.
Scope and applicability
Read the reference's stated equipment, task, and applicability boundaries. A company-wide page does not establish local or role-specific applicability.
- Check the scope stated in the approved source.
- Ask the domain owner when the location or task is not covered.
Revision and currency
Use the revision, effective-date, or currency indicator provided by the authoritative source. This site does not declare which version is current.
- Record the title and revision shown.
- If the indicator is absent or unclear, request confirmation.
Conflicting information
When two sources disagree, preserve the conflict and get an accountable technical or domain-owner decision before relying on either disputed detail.
- Name both sources and the conflicting statements.
- Route the question through the established support handoff.
