ATT - 15th Floor Legend.png

This image is a Partition Legend that provides a detailed key for architectural and fire safety design specifications. The legend outlines various types of fire and smoke barriers with specific color-coded and patterned indicators for different fire resistance ratings and zone classifications. Key elements include 2-hour and 1-hour fire/smoke zone barriers, smoke resistive hazardous room enclosures, non-rated smoke partitions, health care occupancy corridors, sprinkler and fire alarm zone boundaries, and exit stairwell/passageway indicators. The color and line style variations communicate critical information about fire protection, smoke containment, and emergency egress requirements for building design and safety compliance.
