How long do ILSM stay in effect after construction ends?
ILSM stay in effect until the normal life safety protections are fully restored and verified — not until the contractor packs up. “Construction ends” and “protections restored” are two different milestones, and ILSM covers the gap between them. Terminating ILSM early, before fire systems are back online and barriers are intact, is one of the most common ILSM deficiencies surveyors cite.
The closeout sequence
- Physical work completes — construction finishes in the affected area.
- Protections are restored — fire alarm, detection, and suppression systems returned to full operation; temporary equivalent systems removed; smoke/fire barriers repaired and verified; penetrations firestopped.
- Restoration is verified — systems tested, barrier integrity confirmed, egress paths confirmed clear and correctly signed.
- ILSM is formally terminated — the termination is documented: date, what was restored, who verified it, and sign-off by the responsible party.
Steps 2 and 3 are where organizations get impatient. The punch list isn’t the finish line — verified restoration is.
What about deficiencies (not construction)?
When ILSM covers a Life Safety Code deficiency rather than a project, it stays in effect until the deficiency is corrected — documented through the Plan for Improvement process. If correction runs long, the ILSM documentation must stay live the entire time: daily inspections, drill records, training logs. A deficiency corrected in month nine with ILSM logs that stop in month three is a finding.
The documentation tail
After termination, keep the full ILSM record — assessment, daily inspection logs, drill and training records, termination sign-off — with the project’s life safety file. Surveyors review past projects, and a complete closed-out record proves the program works end to end.
Closeout is a life safety event, not an administrative one.
See the ICRA/ILSM construction guide and the Joint Commission’s stance on ILSM during construction.
FAQ
Can ILSM end when the contractor demobilizes?
No — ILSM ends when life safety protections are restored and verified, and the termination is documented with sign-off. Demobilization is a construction milestone, not a life safety one.
Who signs off on ILSM termination?
The party designated in the facility’s ILSM policy — typically the safety officer or facilities leadership — after verification that systems are restored and tested.
How long must ILSM records be kept?
Keep the complete record (assessment, logs, drill/training records, termination) with the project file. Surveyors review historical projects; treat ILSM records as permanent life safety documentation.
