📄Floor-by-Floor Map Requirements

Floor-specific diagrams are often useful and may be required by an adopted code or AHJ. Where used, a draft can show available stair routes, alternate options, floor identification, and how that floor relates to the emergency plan. Verify every route in the building and confirm diagram and posting duties locally.

📋Stairwell vs. Elevator Rules

  • 📋Stairwells are the primary means of evacuation for upper floors
  • 📋Elevators should NEVER be used during fire evacuations
  • 📋Evacuation maps must mark elevators as "NOT for evacuation use"
  • 📋Stairwells must be enclosed with fire-rated doors
  • 📋Each stairwell should be numbered or named for identification
  • 📋Maps should show which floors each stairwell serves

📄Assembly Points for Multi-Floor Buildings

Multi-floor buildings often designate a single outdoor assembly point for all floors, or separate zones for different sections of the building. Assembly points should be: far enough from the building to avoid falling debris, accessible for emergency vehicles, large enough for all occupants, and away from streets with heavy traffic.

📋Where to Post Multi-Floor Maps

  • 📋Stairwell entrances or elevator lobbies where required or useful for orientation
  • 📋Floor entrances, common areas, or high-occupancy areas selected through site and AHJ review
  • 📋Accessible emergency areas when applicable and verified
  • 📋Any locations specifically required by the adopted code

📄High-Rise Building Considerations

Buildings over 75 feet may have additional requirements under local fire codes, including: refuge floors, firefighter service elevators, voice evacuation systems, and defend-in-place strategies for certain populations. Consult your local fire marshal for high-rise specific requirements beyond federal OSHA standards.

Expert Advice: Stairwell Strategy

Captain James WilsonHigh-Rise Fire Rescue Specialist, FDNY (Ret.)

The most dangerous assumption in multi-floor evacuations is that everyone will use the nearest stairwell. In reality, 60% of occupants head to the stairwell they normally use, regardless of their location during the emergency. Your evacuation maps need to override this instinct. Use bold, contrasting colors and large arrows pointing to the NEAREST stairwell from each map location. Number or name your stairwells consistently across all floors (Stairwell A, Stairwell B). During drills, deliberately have people evacuate using different stairwells so they learn multiple routes. One blocked stairwell shouldn't mean everyone is trapped.

🏭Industry-Specific Multi-Floor Considerations

🏢

Office Buildings

  • Designate floor wardens for each floor to coordinate evacuation
  • Include conference room capacities to ensure headcount accuracy
  • Mark printer rooms and server closets that may be occupied
  • Show accessible routes for mobility-impaired employees
🏨

Hotels & Hospitality

  • Confirm guest-room diagram duties with the hotel licensing authority and AHJ
  • Include room number ranges served by each stairwell
  • Mark ice machine and vending alcoves on routes
  • Show elevator lobby evacuation alternatives
🏥

Healthcare Facilities

  • Include horizontal evacuation zones for defend-in-place
  • Mark medical gas shutoff locations on each floor
  • Show patient evacuation routes separate from visitor routes
  • Include bed staging areas for non-ambulatory patients

Frequently Asked Questions

Not under a universal federal rule. An adopted code or AHJ may require floor-specific diagrams. Where they are used, verify the floor, available stair routes, location marker, and relevant equipment against actual conditions.

No. Standard evacuation protocol prohibits elevator use during fire emergencies because elevators may malfunction, open on the fire floor, or trap occupants. Evacuation maps should clearly mark elevators as NOT for emergency use.

Assembly points should be at least 100 feet from the building, away from areas where debris might fall, accessible to emergency vehicles, and large enough to accommodate all building occupants.

Confirm posting locations with the AHJ under the locally adopted code and occupancy rules. If diagrams are required, decision points such as stair or elevator lobbies may be appropriate, and each copy should be reviewed for location-specific orientation.

Defend-in-place moves occupants horizontally to a protected smoke compartment on the same floor instead of immediately down the stairs. It is common in hospitals, nursing homes, and high-rises where full vertical evacuation is not practical. The applicable NFPA 101 occupancy chapter and the building fire safety plan govern when it applies, and multi-floor maps should mark smoke compartments and areas of refuge.

Yes, where they exist. An area of refuge is a fire-rated space — often a stairwell landing — where occupants who cannot use stairs can await assisted rescue. The International Building Code (IBC) and ADA require accessible areas of refuge in many multi-story buildings, and NFPA 101 addresses their use. Mark each area of refuge and its two-way communication device on the floor diagram.
