    Detailed Explanation

    Stairwell identification signs provide critical wayfinding during emergencies:

    1. **Required Information**: - Floor level designation (tactile numbers, 4" minimum height) - Stair identification (e.g., "STAIR A") - Whether roof access is available - Which floors have re-entry to the building

    2. **Location**: On the wall at the landing, visible from the door and the flight of stairs above and below.

    3. **Sign Size**: Typically 12" × 18" or larger to accommodate required information.

    4. **Tactile Requirements**: Floor numbers must be tactile with Grade 2 Braille.

    5. **High-Rise Buildings**: Additional requirements may apply for buildings over 75 feet, including photoluminescent requirements in some jurisdictions.

    • ×Floor numbers less than 4" height
