Physical-Digital Intersection: Beyond the Screen
Why This Matters
Digital accessibility is critical, but it’s only part of emergency preparedness.
When people arrive at physical shelters, they need more than information—they need accessible spaces.
This guide bridges the gap between digital communications and physical safety.
The Problem: Digital-to-Physical Disconnect
Common Scenario:
- You send accessible digital alerts ✅
- People understand the message ✅
- They arrive at the shelter ❌
- The shelter cannot meet their needs ❌
Result: Digital success, physical failure.
Two Critical Components
1. Functional Needs Registries
Know who needs help before the emergency happens.
2. Environmental Accessibility
Make physical spaces safe for everyone.
Part 1: Functional Needs Registries
What They Are
Definition: Databases that identify people who will need extra support during emergencies.
Purpose: Connect vulnerable residents with resources proactively.
Examples:
- emPOWER Database (USA - Medicare beneficiaries with electricity-dependent medical equipment)
- Special Needs Registries (Municipal databases)
- Vulnerable Population Lists (Regional emergency management)
emPOWER Database
Official Resource: HHS emPOWER Map
What It Tracks:
- People using electricity-dependent medical equipment
- Oxygen concentrators
- Ventilators
- Suction machines
- Electric wheelchairs
Who Can Access:
- Emergency management agencies
- Public health departments
- Utility companies
- Disaster response teams
How It Helps:
- Prioritize power restoration
- Conduct wellness checks
- Evacuate high-risk individuals first
- Allocate backup generators
Important Note: emPOWER uses Medicare data. It does not capture:
- Non-Medicare populations (younger people with disabilities)
- People without formal healthcare
- Equipment not covered by Medicare

Creating a Functional Needs Registry
Aspiration vs. Reality:
Many municipalities aspire to maintain comprehensive registries, but face challenges:
- Privacy concerns - People fear disclosure
- Opt-in rates - Research indicates rates often remain below 40% for voluntary emergency alert registration systems
- Data staleness - Needs change quickly
- Resource constraints - Maintenance is time-intensive
Best Practices (Based on Successful Programs):
- Make Registration Easy
- Online form (accessible)
- Phone registration option
- Mail-in paper form
- In-person at community centers
- Protect Privacy
- Clear data use policies
- Limit access to authorized personnel
- Encrypt sensitive information
- Regular security audits
- Keep Data Current
- Annual renewal requirement
- Prompt for updates during 311 calls
- Partner with healthcare providers
- Automated reminders
- Define “Functional Needs”
- Mobility limitations
- Cognitive or developmental disabilities
- Vision or hearing loss
- Medical equipment dependency
- Service animal reliance
- Language barriers
- Transportation needs
- Plan for Non-Registrants
- Assume incomplete data
- Door-to-door checks
- Partner with community organizations
- Multiple outreach channels
Registry Information to Collect
Essential:
- Name and contact information
- Address (including floor for multi-story buildings)
- Emergency contact
- Functional need category
- Preferred communication method
Helpful:
- Specific medical equipment
- Service animal (type)
- Languages spoken
- Mobility aid type
- Caregiver information
- Alternate shelter needs
Do Not Collect:
- Specific diagnoses (not needed, violates privacy)
- Medical records
- Financial information
Using Registry Data
Power Outages:
- Contact registrants within 2 hours
- Offer cooling/warming centers
- Provide generator access
- Check in every 4-6 hours
Evacuations:
- Contact registrants first
- Arrange accessible transportation
- Confirm arrival at shelter
- Track throughout event
Shelter Operations:
- Pre-allocate accessible spaces
- Prepare medical support
- Brief staff on needs
- Maintain communication
Part 2: Environmental Accessibility
What It Is
Definition: Making physical spaces safe and usable for people with various sensitivities and disabilities.
Often Overlooked: Chemical sensitivities, environmental triggers, and sensory needs.
Scent-Free Policies
Why It Matters:
Many people have severe reactions to fragrances and chemicals:
- Asthma attacks
- Migraines
- Seizures
- Respiratory distress
In Emergency Shelters:
Stress and proximity make reactions worse. A person who can tolerate fragrances normally may have severe reactions in a crowded shelter.
Implementing Scent-Free Shelters:
- Pre-Emergency Communication
- Post scent-free policy on shelter information
- Include in registration materials
- Explain in community outreach
- Provide rationale (health, not preference)
- At the Shelter
- Post clear signage at entrance
- Provide unscented supplies
- Designate scent-free zones
- Educate staff and volunteers
- What “Scent-Free” Means
- No perfume, cologne, or aftershave
- Unscented personal care products
- No air fresheners or scented candles
- Use unscented cleaning products
- No smoking before entering
- Be mindful of laundry detergents
- Provide Alternatives
- Unscented soap and shampoo
- Fragrance-free wipes
- Unscented deodorant
- Basic toiletries on-site
Sample Signage:
SCENT-FREE ZONE
This shelter maintains a scent-free environment
for the health and safety of all residents.
Please refrain from:
✗ Perfume, cologne, aftershave
✗ Scented lotions or products
✗ Air fresheners
✗ Smoking before entering
Unscented supplies available at desk.
Thank you for helping keep everyone safe.
Chemical Sensitivity Accommodations
Beyond Fragrances:
- Cleaning Products: Use green-certified, unscented products
- Pest Control: Avoid spraying during occupancy
- New Materials: Air out new bedding/supplies before use
- Ventilation: Maximize fresh air circulation
- Designated Areas: Create low-chemical zones
Sensory Accessibility
Lighting:
- Provide dimmer switches
- Avoid fluorescent lighting (triggers migraines, seizures)
- Create “quiet, dim” zones for sensory breaks
- Offer eye masks
Noise:
- Designate quiet zones
- Provide earplugs
- Minimize PA announcements
- Offer noise-canceling headphones if available
Visual Clutter:
- Clear signage

Case Study: 2021 Texas Winter Storm
Situation: Widespread power outages during extreme cold.
Digital Success:
- Alerts sent in multiple languages
- Crisis Mode website accessible
- Social media updates frequent
Physical Failure:
- No registry of electricity-dependent medical equipment
- Shelters unprepared for environmental sensitivities
- Chemical cleaning products triggered reactions
- No scent-free zones
Result:
- Many people with disabilities couldn’t access shelters
- Medical equipment failures led to hospitalizations
- Environmental triggers caused additional health crises
Lessons Learned:
- emPOWER data would have enabled proactive outreach
- Scent-free policies would have made shelters accessible
- Environmental planning is as critical as digital access
Moving Forward
Digital accessibility is necessary but not sufficient.
Emergency preparedness must bridge digital communications with physical safety.
Key Principles:
- Know who needs help (Registries)
- Make spaces safe (Environmental accessibility)
- Connect digital and physical (Integrated planning)
- Learn and improve (Continuous feedback)
Start today:
- Review your functional needs registry
- Establish scent-free policies
- Train staff on environmental accessibility
- Test your physical-digital integration
When digital alerts reach someone, but the physical shelter cannot accommodate them, we have not succeeded. True inclusivity spans both realms.
