The Power Is Out: Keep an Occupied Facility Under Control

Make defensible occupancy decisions and coordinate system-by-system restoration.

BuildingWrench editorial team · September 18, 2026 · Management coordination, not a repair procedure

Safety first

Keep clear of downed lines, damaged electrical equipment and flooded spaces. Report fire, injury or entrapment to emergency services. Do not attempt elevator rescue or improvised electrical connections.

Your job is to create a clear response: protect people, establish ownership, coordinate qualified help and keep a reliable record. Use the site-specific emergency plan and responder instructions ahead of this general guide. Local requirements, building use and the actual conditions determine what is permitted.

Start with people, not the switchboard

Activate the site outage procedure. Establish whether occupants can use safe exit routes and receive instructions. Use trained staff for accountability at designated locations; do not send them into dark or hazardous areas. Give responders the exact location of anyone needing assistance.

Build a critical-service picture

Have responsible staff report the status of emergency lighting, alarms, access-controlled doors, communications, elevators, water systems and essential operations. Record unknowns as unknowns. Backup power does not necessarily serve the whole building. Loss of a critical safety function requires escalation under the emergency plan, not an assumption that the generator has covered it.

Separate the utility problem from the building problem

Contact the utility and qualified electrical contractor as appropriate. Record ticket numbers and whether an estimated restoration time is confirmed or provisional. Do not repeatedly reset breakers to chase the outage. Leadership needs two answers: what operating conditions are available now, and what will trigger relocation or closure?

Control temporary arrangements

Route temporary-power proposals through qualified personnel and site approval. Portable generators must never operate indoors; CDC warns that exhaust can enter through openings. Do not backfeed through an outlet. Track the purpose, responsible operator, fuel arrangements and restrictions for each approved temporary installation.

Treat restoration as a managed restart

Utility power returning is the start of verification. Coordinate restart sequencing with the electrical and equipment specialists. Assign owners to confirm alarms, doors, lifts, controls and critical loads. Record faults that remain. Communicate which areas are released and which remain restricted; do not announce an all-clear solely because lights returned.

What to tell occupants

Adapt this example to confirmed facts and approved instructions. Replace every bracketed field before sending. Never issue an all-clear without the responsible authorization.

The building is experiencing a power outage. Follow staff instructions and do not use elevators. [Affected area] is closed. The utility estimate is unconfirmed; our next operational decision is at [time].

Common management mistakes

Build the incident record

Finish the handoff

Before leaving or changing shifts, name the next responsible person, outstanding restrictions, expected contractor attendance and the next decision time. Confirm they received the handoff. Keep emergency work, temporary measures and permanent corrective work as separate tracked items so the visible symptom does not become the only thing that gets closed.
