Smoke is reported in a mechanical room two floors below the NICU. The alarm is sounding. In the unit, nine infants rest in incubators, three on respiratory support. The charge nurse faces a decision that has to be made in seconds: keep these babies where they are and defend the unit, or start moving them down the stairs?
That decision—shelter in place or evacuate—is one of the hardest in hospital emergency response. The instinct to “just get everyone out” is understandable, but for non-ambulatory infant patients, evacuation itself carries real risk. It is not automatically the safe choice.
This guide offers a structured way to think about that decision before an emergency forces it: the range of responses, why the choice is harder in infant units, the factors that should drive it, and a checklist your team can adapt. Your incident command structure makes the call in the moment; the goal here is to make sure that moment doesn’t catch anyone flat-footed.
Understanding the Range of Responses
People frame the choice as a simple binary: stay or go. In reality there’s a spectrum, and the best answer often sits in the middle.
- Shelter in place (defend in place). Keep patients where they are and protect them from the threat. In hospital fire response this is often the default, because modern hospitals are built with fire-resistant construction and compartmentation so a fire in one area can be contained while patients elsewhere stay put. It avoids the risks of moving fragile patients.
- Horizontal evacuation. Move patients through fire or smoke barriers into a separate compartment on the same floor. This middle path removes patients from immediate danger without the difficulty and risk of stairs.
- Vertical evacuation. Move patients down stairwells to lower floors or out of the building. For infant units above ground level this is the most demanding option, requiring specialized equipment, careful stairwell control, and more staff time per patient than any other response.
- Full facility evacuation. Empty the building entirely. This is rare and usually driven by a threat to the whole structure, such as an approaching wildfire or flood.
Why the Decision Is Harder for Infant Units
The choice is difficult anywhere in a hospital. In NICUs, maternity wards, and nurseries, several factors sharpen it.
Patients cannot self-evacuate. On most floors, some patients can walk out with minimal help. In an infant unit, that number is zero—every patient must be carried or transported, which turns evacuation into an equipment-and-staffing operation.
Movement itself carries risk. Transport can interrupt monitoring, disrupt respiratory support, and expose infants to temperature loss. For the smallest and sickest patients, the act of evacuation introduces clinical risks that don’t exist while the infant remains in a stable, climate-controlled incubator. This is the central reason “just evacuate” isn’t automatically correct.
Staffing is thin, especially overnight. A nighttime fire might find three or four staff responsible for a full unit. The decision to evacuate must be realistic about how many infants that team can actually move, and how fast.
Equipment determines what’s possible. Carrying infants one at a time requires about one staff member per infant—rarely feasible in a real event. An evacuation sled that carries six infants with automatic braking for stairwell descent lets a single staff member move many infants under control, which can make vertical evacuation viable when individual carrying would not be.
The Decision Framework: Factors That Drive the Choice
When an emergency begins, the incident command structure weighs several factors together. No single one decides the outcome.
- Nature and location of the threat. A small, contained fire two compartments away is very different from heavy smoke entering the unit. A threat the building can contain favours sheltering; one that defeats the building’s protections favours moving. Where the hazard sits relative to the infants and their exits matters as much as what it is.
- Time available. A slow-building threat like rising water grants time for a careful evacuation. A fast-moving threat like interior smoke may make full evacuation impossible to complete safely, which can favour defending in place within a protected compartment.
- Patient acuity. Stable, growing infants tolerate movement better than critically ill ones on high support. The sickest infants are precisely those for whom transport is most dangerous. This is a clinical judgment for qualified providers.
- Building features. Fire-resistant construction, compartmentation, smoke control, and sprinklers all support defending in place. Weaker protections lean toward movement.
- External conditions. Clear versus smoke-filled stairwells, ready receiving areas, safe weather outside, and guidance from emergency services all shape the decision.
A Comparison at a Glance
| Factor | Favours Sheltering / Defending in Place | Favours Evacuation |
|---|---|---|
| Threat containment | Building can contain the threat | Threat defeats building protections |
| Threat speed | Fast-moving; no time to move all infants | Slow-building; time to evacuate carefully |
| Patient acuity | Many high-acuity, unstable infants | Mostly stable infants |
| Staffing | Thin team relative to patient count | Adequate staff and equipment for the count |
| Building protection | Strong compartmentation and fire resistance | Weak protection or compromised structure |
| Egress routes | Stairwells or exits compromised | Routes clear and receiving areas ready |
| Equipment | Limited transport capacity | High-capacity transport available |
This table is a thinking aid, not a scoring formula. Real events present mixed signals, and the incident commander must weigh them together.
Carrying Out Each Response
Sheltering in place shifts the unit into protection mode: close doors to contain smoke, account for every infant, maintain monitoring and respiratory support as normal, report status to incident command, and stage evacuation equipment near the exit in case conditions change. It’s an active defence, not a passive wait.
Horizontal evacuation bridges the gap when the current compartment is no longer ideal but a full exit isn’t warranted. Moving infants through barriers into an adjacent compartment preserves most of the advantages of sheltering—no stairs, less transport risk, faster execution—while removing patients from the immediate threat. For many fire scenarios in compartmented hospitals, this is the safest realistic response.
Vertical evacuation is the most demanding, and equipment shapes whether it’s feasible with the staff on hand. Bring transport equipment to the staging point, load infants as clinical leaders direct, maintain respiratory support for those who need it, and control the descent carefully—stairwells are where transport risk concentrates. The EvacuB evacuation sled addresses this with automatic braking that engages during descent, letting a single staff member maintain controlled speed while transporting six infants, plus integrated oxygen cradles for continuous oxygen delivery during the move. Account for every infant on arrival, and re-establish monitoring and warming as quickly as possible.
Who Makes the Call
The decision belongs to the facility’s incident command structure, not to an individual acting alone. Initial protective actions like closing doors may start before formal command is established, guided by unit protocols, but escalation to vertical or full evacuation should flow through the chain of command. That’s why staff should know, before any alarm, who holds authority to order an infant evacuation and how unit status gets reported.
A Decision and Readiness Checklist
Adapt this to your facility, post a version in the unit, and build it into your drills.

About EvacuB
EvacuB manufactures purpose-built infant evacuation equipment serving NICUs, maternity wards, and well-baby nurseries. Our evacuation systems accommodate six infants per unit, with automatic braking for controlled stairwell descent and integrated oxygen cylinder cradles that support infants requiring respiratory support during transport.
The shelter-or-evacuate decision often hinges on whether vertical evacuation is realistic for the staff on hand. Equipment that lets a single staff member move six infants under control on a stairwell expands the range of situations in which evacuation is a safe, achievable option rather than a last resort that exceeds the team’s capacity.
Contact us to learn how EvacuB equipment can support both the sheltering and evacuation provisions of your infant unit’s emergency planning.
Frequently Asked Questions
Is it always safer to evacuate infants during a fire?
No. For non-ambulatory infants, movement itself carries real risks, including interrupted monitoring, disrupted respiratory support, and temperature loss. Modern hospitals are built with fire-resistant construction and compartmentation specifically so many fires can be managed by defending patients in place or moving them horizontally, rather than by full evacuation.
What does “defend in place” mean in a hospital?
Defend in place, a form of sheltering in place, means keeping patients where they are and protecting them using the building’s features—closing doors, relying on compartmentation and fire resistance, and letting fire systems contain the event. It’s a common default for hospital fire response because moving fragile patients introduces its own dangers.
What is the difference between horizontal and vertical evacuation?
Horizontal evacuation moves patients to a separate, protected compartment on the same floor, avoiding stairs. Vertical evacuation moves patients down stairwells to lower floors or out of the building. Horizontal movement is faster and lower-risk for infants; vertical evacuation is reserved for situations where staying on the floor is no longer safe.
Who decides whether to shelter or evacuate?
The facility’s incident command structure, not an individual acting alone. Unit protocols may guide immediate protective actions like closing doors or starting horizontal movement, but escalation to vertical or full evacuation should flow through the chain of command. Staff should know in advance who holds authority to order an infant evacuation.
The choice between sheltering in place and evacuating is among the most consequential decisions an infant care team can face. For fragile, non-ambulatory infants, evacuation carries genuine risk and isn’t automatically the safe answer—the safest response is often the least disruptive one that still protects patients.
A sound decision weighs several factors together: the threat, the time available, patient acuity, the building’s protections, the state of egress routes, and the staff and equipment on hand. What makes that moment manageable is preparation. Units that have written clear protocols, assigned decision authority, staged their equipment, and drilled both sheltering and evacuation give their staff a framework to lean on when seconds count.
