Emergency planning with disability and access needs

Standard emergency planning assumes that every household member can self-evacuate quickly on foot. That assumption fails for roughly one in four Americans who live with some form of disability, and for the estimated 2.5 million Americans who depend on powered medical equipment — oxygen concentrators, power wheelchairs, feeding pumps, ventilators — that stops functioning within hours of a power outage. Preparedness plans that ignore these realities don't protect the people who need protection most.

Federal Emergency Management Agency (FEMA)'s framework calls these Access and Functional Needs (AFN) — recognizing that the needs are operational planning problems, not personal limitations. Planning around specific needs produces workable solutions. Planning around generic categories does not.

Build person-specific profiles

Start with a written profile for each household member who has access needs. The profile drives every other planning decision.

Document for each person:

  • Mobility baseline: Can they walk independently, with assistance, or only with a device? How far? At what pace?
  • Transfer needs: Can they move from wheelchair to car seat independently, or does it require two people?
  • Power-dependent equipment: What devices require power, what is the battery backup duration, and what is the consequence of a power failure?
  • Medications: Which medications are essential, what is the required temperature range for storage, and how many days of supply are on hand?
  • Communication needs: Does this person communicate using an AAC device, hearing aids, or other augmentative technology? What is the backup if that device fails?
  • Heat/cold tolerance: Some conditions (MS, spinal cord injury) make temperature regulation difficult; extreme heat or cold becomes a life-safety issue faster than for others

Field note

Write this profile on a single laminated card. Keep one with the person's medications, one with the go-bag, and one with the primary caregiver. A caregiver who is rushed during an evacuation does not have time to recall complex medical histories under stress — the card does it for them.

Power-dependent equipment: the 72-hour problem

A power outage that lasts 72 hours is a planning benchmark for most households. For someone dependent on an oxygen concentrator, home dialysis, or an electric wheelchair, that 72-hour window can be a life-threatening emergency. The calculation is specific to each device.

Oxygen concentrators draw 300–600 watts continuously and have no internal battery — they stop working the moment grid power fails. Options:

  • Maintain a supply of portable oxygen tanks as backup — confirm flow rate, tank size, and duration with your prescribing physician and have at least 72 hours of tank oxygen on hand
  • A battery-powered portable concentrator provides a rechargeable bridge; a 6,700 mAh portable unit typically provides 4 hours of runtime at low flow settings. This is supplement capacity, not replacement for a full backup tank supply.
  • Register with your utility's medical baseline or life support equipment program to receive priority restoration notification and, in some jurisdictions, priority reconnection

Power wheelchairs: Most power wheelchair batteries require 6–8 hours of charging at 200–500 watts and provide 12–24 hours of normal use on a full charge. In a power outage, the chair becomes immobile when the battery depletes. Options:

  • Keep the chair at full charge at all times — charge overnight every night, not when the indicator drops
  • A portable power station with 500+ watt-hours can recharge most power wheelchair batteries once; calculate your specific chair's charger wattage to confirm compatibility
  • A lightweight manual transport chair (15–20 lbs (6.8–9 kg)) provides mobility when the power chair is immobilized; it cannot substitute for daily use but enables evacuation
  • Confirm whether your power chair has a 12V car adapter for the charger — if it does, vehicle charging is a backup option while rolling

CPAP and BiPAP machines: Most draw 30–90 watts. A 300 watt-hour portable power station runs a CPAP for one to three nights depending on pressure settings. CPAP mobile apps often show actual power draw. Measure yours specifically.

Other powered devices: For each device in your plan, document: - Device wattage (on the label or in the manual) - Required runtime per 24 hours - Battery backup duration on internal battery (if any) - Compatible external power station capacity

A portable power station's runtime on a given device equals its watt-hour capacity divided by the device's wattage. Example: a 500 Wh power station running a 45-watt CPAP provides approximately 11 hours of runtime. Build from actual numbers, not marketing claims.

Stair and multi-floor egress

Elevators must not be used during fire or seismic events. For wheelchair users in multi-story buildings, stair descent requires planning before the emergency.

Evacuation chairs are purpose-built devices that allow a single attendant to safely guide a mobility-impaired person down stairs. A governor controls descent speed to approximately 1 meter per second (3 feet/second), allowing a small attendant to manage a significantly heavier passenger. Models designed for buildings can be stored in a stair enclosure and deployed in under two minutes.

If you live in a multi-story building and use a wheelchair or have limited stair mobility:

  • Identify which floor exit leads to grade (not all ground floors connect directly to street level)
  • Know where the nearest area of refuge is on your floor — a fire-rated enclosure designed as a waiting area for emergency responders
  • Ensure at least two trained people know your evacuation procedure and have practiced it

Caregiver backup planning

A plan dependent on a single caregiver fails the moment that caregiver is unavailable, injured, or unreachable.

Cross-train at least two additional people who can provide support:

  • A neighbor who can initiate evacuation if the primary caregiver cannot be reached
  • A family member in the area who knows the access needs, equipment location, and medical priorities
  • A friend or community member enrolled in a mutual aid network

Establish a check-in protocol: during any developing emergency, the person with access needs calls or texts a pre-designated contact at a set interval. If check-in is missed, the contact initiates the backup plan. See mutual aid networks for how to formalize this within a community structure.

Medication planning for access needs

For prescription medications that cannot be interrupted — anticoagulants, insulin, antiseizure medications, psychiatric medications — the planning standard is a 7-day minimum supply, with 30 days as a more robust target.

Insulin: Requires refrigeration at 36–46°F (2–8°C) for unopened vials. Once opened, most insulin formulations remain effective for 28 days at room temperature between 59–77°F (15–25°C) — confirm the specific window for your insulin type with your prescribing physician, as formulations vary. In a power outage: - A dedicated small medical cooler with ice packs can maintain appropriate temperature for 24–48 hours - Insulin should never be frozen — it loses effectiveness permanently - The Frio case (evaporative cooling wallet) uses water activation to keep insulin below 80°F (26.7°C) for 45+ hours without ice — a practical go-bag solution in moderate climates

Temperature-sensitive medications: Identify which of your medications require refrigeration, and how long they can safely remain at room temperature. Your pharmacist can provide this window for each medication. Build an insulated medication carrier into your go-bag and document the temperature tolerance for each medication on a card inside the carrier.

Supply depth: Document the days-on-hand for each essential medication and refill at 30 days remaining for critical medications — not when the bottle runs out. Most insurance plans permit early refills during declared emergencies; confirm your plan's policy in advance. During a federally declared disaster, many state insurance commissioners issue emergency refill orders that waive standard early-refill restrictions.

Backup prescribers and pharmacies: Know what happens to your prescriptions if your regular pharmacy is closed, your physician is unreachable, or you are evacuated to a different region. Most pharmacy chains can fill prescriptions across locations; confirm this with your pharmacy in advance. For controlled substances, transfer is more restricted — understand the specific constraints for any controlled medications you depend on.

Never separate a person from essential mobility and medical devices

During evacuation, the instinct to leave equipment that slows departure can feel practical. It is not. A wheelchair, communication device, or medication pump is survival equipment. Losing it sharply increases medical risk and may create a situation the household cannot manage. Stage the equipment for rapid loading — pre-built ramps for vehicle loading, a pre-packed medication kit in the go-bag — so it never has to be a choice.

Shelter-in-place adaptations

If the access needs profile makes evacuation difficult, a well-prepared shelter-in-place may be the better default option. This requires ensuring:

  • The home can support the person for the expected duration without power (have backup for all powered equipment)
  • Medical supply depth is adequate for extended stays
  • Community support is checked in and can provide assistance

For the shelter-in-place decision framework, see bug-in planning.

Community notification systems

Many counties maintain a special needs registry where residents with mobility or medical equipment dependencies can pre-register. During a declared emergency, this registry enables first responders and emergency managers to prioritize outreach. Registration does not guarantee evacuation assistance, but it ensures responders know where to look first.

Search "[your county] special needs registry" or contact your local emergency management office to register.

Practical checklist

  • Build a written access needs profile for each household member with specific mobility, equipment, and medication details — laminate it, make three copies
  • Identify every power-dependent medical device and document its battery backup duration
  • Register with your utility's life support equipment or medical baseline program
  • Build a power backup plan for each power-dependent device: portable power station, backup batteries, or alternative device
  • Cross-train at least two additional caregivers and practice the evacuation procedure with them
  • Confirm stair descent method for any multi-story building occupant with limited mobility
  • Stock a 30-day supply of essential medications; store in a pre-packed waterproof medication kit
  • Register with your county's special needs registry if applicable
  • Test the full evacuation procedure with all persons and all equipment — time it
