Means of egress in new and existing buildings shall comply with NFPA 101, Life Safety Code.

All inside stairs serving as an exit or exit component shall be enclosed with 2 hour rated barriers.

Exit enclosures shall not be used for any purpose that has the potential to interfere with its use as an exit.

There shall be no enclosed, usable space within an exit enclosure, including under stairs, nor shall any open space within the enclosure be used for any purpose that has the potential to interfere with egress.

3.2. Doors

Any device or alarm installed to restrict the improper use of a means of egress shall be designed and installed so that it cannot, even in case of failure, impede or prevent emergency use of such means of egress.

Swinging doors shall swing in the direction of egress travel where serving a room or area with an occupant load of 50 or more or serving a high hazard contents, unless it is a door from an individual living unit that opens directly into an exit enclosure.

Swinging doors shall swing in the direction of egress travel and provided with panic hardware where serving a room or area with an occupant load of 100 or more. Devices shall not be installed in connection with any door on which panic hardware or fire exit hardware is required where such device prevents or is intended to prevent the free use of the door for purposes of egress.

Doors shall be arranged to be opened readily from the egress side whenever the building is occupied. Locks, if provided, shall not require the use of a key, a tool, or special knowledge or effort for operation from the egress side.

Stair exit and fire pump room doors shall be self closing, self latching, listed and labeled 90 min fire rated doors. Doors to other hazardous rooms shall be 45 min rated doors unless different door ratings are required by adopted codes.

Every door in a stair enclosure serving more than four stories shall allow re-entry from the stair enclosure to the interior of the building, or an automatic release shall be provided to unlock all stair enclosure doors to allow re-entry. Such automatic release shall be actuated with the initiation of the building fire alarm system.

Delayed-egress locks shall be permitted to be installed on doors serving low and ordinary hazard contents in buildings protected throughout by an approved, supervised automatic fire detection system, or an approved, supervised automatic sprinkler system, where permitted by the occupancy classification, and as approved by EHSRM. The doors shall unlock upon actuation of the alarm or the sprinkler system, loss of power controlling the lock, or an irreversible process of a force to the release device continuously applied as required by EHSRM.

The minimum width of room doors in existing buildings shall not be less than 71 cm.

The minimum width of egress doors in existing buildings shall not be less than 91 cm.

The minimum width of egress doors in the medical center shall not be less than 112 cm.

3.3. Number of Means of Egress

The number of means of egress from any balcony, mezzanine, story, or portion thereof shall be not less than two.

Occupant load more than 500 but not more than 1,000 — not less than 3 Occupant load more than 1,000 — not less than 4

The occupant load of each story considered individually shall be required to be used in computing the number of means of egress at each story, provided that the required number of means of egress is not decreased in the direction of egress travel.

3.4. Arrangement of Means of Egress

Exits shall be located and exit access shall be arranged so that exits are readily accessible at all times.

Where more than one exit is required from a building or portion thereof, such exits shall be remotely located from each other and shall be arranged and constructed to minimize the possibility that more than one has the potential to be blocked by any one fire or other emergency condition.

Exit access shall be arranged so that there are no dead ends in corridors, unless permitted by and limited to the length specified in NFPA 101, Life Safety Code for the specific occupancy and condition.

3.5. Occupant Load

The occupant load in any building or portion thereof shall be not less than the number of persons determined by dividing the floor area assigned to that use by the occupant load factor for that use as specified in Table 3.5.

Where exits serve more than one story, only the occupant load of each story considered individually shall be used in computing the required capacity of the exits at that story, provided that the required egress capacity of the exit is not decreased in the direction of egress travel.

3.6. Illumination of Means of Egress and Emergency Lighting

Illumination of means of egress shall be provided for every building and structure. This illumination shall be maintained and shall be not less than 10.8 lux measured at finished floor level.

Illumination of means of egress shall be continuous during the time that the conditions of occupancy require that the means of egress be available for use. Artificial lighting shall be employed at such locations and for such periods of time as required to maintain the illumination to the minimum a minimal criteria.

A functional test shall be conducted by PPD or PEMC on every required emergency lighting system at 30-day intervals for not less than 30 seconds. An annual test shall be conducted on every required battery-powered emergency lighting system for not less than 1½ hours.

Equipment shall be fully operational for the duration of the test. Written records of visual inspections and tests shall be kept by PPD or PEMC and made available upon request for review by EHSRM.

3.7. Marking of Means of Egress

Exits shall be marked by an approved sign readily visible from any direction of exit access.

Access to exits shall be marked by approved, readily visible signs in all cases where the exit or way to reach the exit is not readily apparent to the occupants. Sign placement shall be such that no point in an exit access corridor is in excess of 30 m from the nearest externally illuminated sign and is not in excess of the marked rating for internally illuminated signs.

Every sign shall be suitably and continuously illuminated by a reliable light source.

A sign with a directional indicator showing the direction of travel shall be placed in every location where the direction of travel to reach the nearest exit is not apparent.

AUB has adopted a UL listed pictogram type, maintained LED exit sign, with built-in battery pack installed in all AUB and AUBMC Buildings.

3.8. Means of Egress Reliability

Means of egress shall be continuously maintained free of all obstructions or impediments to full instant use in case of fire or other emergency.

3.9. Furnishings and Decorations in Means of Egress

No furnishings, decorations, or other objects shall obstruct exits, access thereto, egress there from, or visibility thereof.
