215 patients, no elevators: the hospital evacuation that went right
When Sandy flooded NYU Langone and the backup generators failed, staff carried roughly 215 patients — including critical-care adults and NICU newborns — down dark stairwells. Here's why it worked.
On the night of October 29, 2012, Hurricane Sandy's storm surge flooded the basements of NYU Langone Medical Center in Manhattan and knocked out the backup generators. With no power and no elevators, staff and firefighters evacuated roughly 215 patients down darkened stairwells — including about 45 critical-care patients and NICU newborns whose most fragile infants were hand-ventilated on the way down. No patient deaths were attributed to the evacuation. It is the counterexample to every disaster story: proof that vertical evacuation of non-ambulatory patients, in the worst conditions, can be done — when a facility has planned, equipped, and practiced for it.
What happened at NYU Langone during Sandy?
Hospitals are built to shelter in place — to "defend in place" behind fire-rated construction rather than move fragile patients. But defend-in-place assumes the building's systems hold. On October 29, 2012, they didn't: Sandy's surge flooded NYU Langone's lower levels and disabled the emergency generators, leaving the hospital dark and without elevators.
Staff made the call to evacuate. Over the following hours, teams carried roughly 215 patients down the stairwells by hand and on sleds and stretchers — including intensive-care patients and premature newborns from the NICU, with clinicians manually squeezing bags to keep the smallest infants breathing. Firefighters and staff worked the flashlit stairs together. Widely reported afterward, the evacuation became a turning point in how hospitals think about backup-power siting and stairwell evacuation.
Why is moving non-ambulatory patients so hard — and how did they do it?
A hospital's sickest patients are, by definition, the least mobile: sedated, ventilated, post-surgical, newborn. Moving them down stairs requires equipment, trained hands, and a sequence — you can't simply tell people to walk out. The default strategy of horizontal relocation into an adjacent smoke compartment only works while the building and its power hold.
NYU's evacuation worked because people were prepared to improvise around a plan: teams knew the stairwells, had devices to move patients, and had a triage sense of who moved in what order. It was heroic — but it was heroism riding on preparation, not instead of it.
What does it mean for any care facility?
The CMS Emergency Preparedness Rule requires hospitals, skilled nursing, and other providers to have a documented plan and the means to evacuate patients when sheltering in place fails. NYU Langone shows what that capability looks like when it's real: staged equipment for moving non-ambulatory patients down stairs, staff who've practiced on the actual floors, and a clear order of operations.
The facilities that make the news for the wrong reasons — the ones where residents couldn't be moved when the power failed — are usually the ones that had a plan on paper and nothing behind it. The difference is drills and gear, decided in advance.
- ›Know your trigger: defend-in-place is the default, but write down the conditions that flip you to evacuation before you're in them.
- ›Stage the means to move non-ambulatory patients down stairs — evacuation chairs and transfer devices — on the patient floors, not in a basement store room.
- ›Practice on your actual stairwells with your actual staff; a vertical evacuation is a choreography, and choreography needs rehearsal.
- ›Site your backup power and fuel above flood level — the failure that started NYU's night was generators in the basement.
- ›Build a patient-triage order for evacuation now, so no one is deciding who goes first in the dark.
Questions professionals ask
Yes. The CMS Emergency Preparedness Rule (42 CFR §482.15 for hospitals, §483.73 for long-term care) requires a documented, all-hazards emergency plan that includes the means to shelter in place or evacuate patients when required, and it's surveyed for compliance. The Joint Commission's Life Safety and Environment of Care standards reinforce it.
Defend-in-place is the healthcare strategy of protecting patients behind fire-rated construction and moving them horizontally into an adjacent smoke compartment rather than evacuating the building. It's the right first move — but it assumes the building's structure and power hold. When a flood, sustained fire, or grid failure removes those, vertical evacuation becomes necessary.
With staged equipment and trained staff: evacuation chairs and transfer devices let teams move patients down stairwells under control, in a planned order, without unsafe lifting. The key is that the equipment, training, and triage sequence exist before the emergency — not that they're invented during it.
