| | SECTION 8.6.7 |

| | EXISTING, PREVIOUSLY APPROVED ATRIUMS. |
| | (B) ANY NUMBER OF LEVELS OF THE BUILDING SHALL BE |

| | ENCLOSURE, BASED ON THE RESULTS OF THE ENGINEERING |
| | ANALYSIS REQUIRED IN 8.6.7(5). |
| | (C) GLASS WALLS AND INOPERABLE WINDOWS SHALL BE |
| | PERMITTED IN LIEU OF THE FIRE BARRIERS WHERE ALL THE |
| | FOLLOWING ARE MET: |
| | I. AUTOMATIC SPRINKLERS ARE SPACED ALONG BOTH SIDES OF |
| | THE GLASS WALL AND THE INOPERABLE WINDOWS AT INTERVALS |
| | NOT TO EXCEED 6 FT (1830 MM). |
| | II. THE AUTOMATIC SPRINKLERS SPECIFIED IN |
| | 8.6.7(1)(C)(I) ARE LOCATED AT A DISTANCE FROM THE GLASS |
| | WALL NOT TO EXCEED 12 IN. (305 MM) AND ARRANGED SO THAT |
| | THE ENTIRE SURFACE OF THE GLASS IS WET UPON OPERATION |
| | OF THE SPRINKLERS. |
| | III. THE GLASS WALL IS OF TEMPERED, WIRED, OR LAMINATED |
| | GLASS HELD IN PLACE BY A GASKET SYSTEM THAT ALLOWS THE |
| | GLASS FRAMING SYSTEM TO DEFLECT WITHOUT BREAKING |
| | (LOADING) THE GLASS BEFORE THE SPRINKLERS OPERATE. |
| | IV. THE AUTOMATIC SPRINKLERS REQUIRED BY 8.6.7(1)(C)(I) |
| | ARE NOT REQUIRED ON THE ATRIUM SIDE OF THE GLASS WALL |
| | AND THE INOPERABLE WINDOW WHERE THERE IS NO WALKWAY OR |
| | OTHER FLOOR AREA ON THE ATRIUM SIDE ABOVE THE MAIN |
| | FLOOR LEVEL. |
| | V. DOORS IN THE GLASS WALLS ARE OF GLASS OR OTHER |
| | MATERIAL THAT RESISTS THE PASSAGE OF SMOKE. |
| | VI. DOORS IN THE GLASS WALLS ARE SELF-CLOSING OR |
| | AUTOMATIC-CLOSING UPON DETECTION OF SMOKE. |
| | VII. THE GLASS IS CONTINUOUS VERTICALLY, WITHOUT |

| | ACCORDANCE WITH SECTION 9.7. |
| | (5) AN ENGINEERING ANALYSIS IS PERFORMED THAT |
| | DEMONSTRATES THAT THE BUILDING IS DESIGNED TO KEEP THE |
| | SMOKE LAYER INTERFACE ABOVE THE HIGHEST UNPROTECTED |
| | OPENING TO ADJOINING SPACES, OR 6 FT (1830 MM) ABOVE |
| | THE HIGHEST FLOOR LEVEL OF EXIT ACCESS OPEN TO THE |
| | ATRIUM, FOR A PERIOD EQUAL TO 1.5 TIMES THE CALCULATED |
| | EGRESS TIME OR 20 MINUTES, WHICHEVER IS GREATER. |
| | (6) WHERE AN ENGINEERED SMOKE CONTROL SYSTEM IS |
| | INSTALLED TO MEET THE REQUIREMENTS OF 8.6.7(5), THE |
