A planned crew roster, a site-presence record and an evacuation accountability result answer different questions. For a data center construction crew, give each an owner and a clear reference under the actual emergency action plan; do not treat a badge list as proof that everyone has been accounted for.
This is an administrative coordination worksheet for planning and reviewing records. During an emergency, follow the approved site plan and the designated emergency personnel immediately. Do not delay reporting an unresolved person while reconciling a spreadsheet, and do not enter an area or attempt a rescue based on this guide.
What does the construction standard require within its scope?
OSHA 29 CFR 1926.35(a) states the section's applicability to emergency action plans required by a particular OSHA standard. Within that scope, 1926.35(b)(3) includes procedures to account for all employees after emergency evacuation has been completed. The responsible employer and safety owner determine the applicable requirements and the actual project arrangements.
The standard's accountability element is a reason to keep actual evacuation evidence separate from a planning count. It does not prescribe this worksheet or say an access-control export alone satisfies the requirement. Cortex Construct is independent and is not affiliated with OSHA.
Which evidence states should the coordination file distinguish?
Before work, confirm which employer supplies the current crew information, who maintains site-presence changes and who receives unresolved-person reports. Use the site's approved channels and restricted records. A shared planning document should not expose personal contact, identity or medical records.
| Evidence state | What it answers | What it does not prove |
|---|---|---|
| Planned roster | Who is expected for the assignment? | Who actually arrived or remains onsite |
| Site presence | What does the approved current record show? | That every movement was recorded correctly |
| Accountability | Who was actually accounted for under the plan? | That an unmatched person is safely absent |
| Unresolved report | What information reached the designated emergency owner? | A completed rescue or final disposition |
| Closure | What authorised outcome was recorded? | Permission for re-entry or restarting work |
Record the time and applicable area with each state. A morning list can become stale when assignments or shifts change. The emergency plan determines the actual method and authority; the coordinator must not invent a replacement process.
How can equal totals conceal an unresolved person?
Illustrative example. A fictional planned roster contains four people identified only as A, B, C and D. A later accountability record lists A, B, C and visitor V. Both lists total four, but D is unresolved against the roster and V needs the separate visitor process. Equal totals do not establish a person-by-person reconciliation.
In a planning exercise, the coordinator documents that mismatch and confirms the approved reporting interface with the responsible owner. In a real event, unresolved-person information goes immediately through the established emergency route. Do not assume D went home, change the expected count to close the gap, or send an untrained person to search.
The example has no real worker information and does not establish an emergency outcome. A later correction to a presence record should retain its time and source rather than erase the original discrepancy.
What should be checked when a crew or work area changes?
Ask the responsible employer and site safety owner which roster, presence and accountability arrangements are affected. Keep the approved plan reference, receiving contact and briefing status current. Do not assume an induction at another site supplies the local emergency instructions.
The first-day induction and access guide covers start readiness. The shift handover checklist covers the continuing assignment handover. This worksheet adds the specific distinction between planned presence and actual evacuation accountability.
Frequently asked questions
Does an active badge prove a person is onsite?
No. Use the approved current presence process and retain unresolved discrepancies.
Does an equal headcount prove everyone is accounted for?
No. Different people can produce the same total; follow the actual accountability procedure.
Does closing the register authorise re-entry?
No. Re-entry and restart remain with the authorised emergency and site owners.
