I understand that Chapter 7 of NFPA 101 applies to stairs on the means of egress.
However, in the case of a feature stair, does the same dimensional requirements and handrails on both sides still apply? In theory, should a person be on the feature stair when the fire alarm activates, they would need to traverse the stair to escape and it therefore forms part of the means of egress?

In the corridors of an apartment building (wrap) there are fire doors that are double-egress pairs that are left-hand-reverse by left-hand reverse which follows the natural traffic pattern within the corridor.  However, there are also several right-hand-reverse by right-hand-reverse in the same corridor.
Is there a requirement one way or another on which direction these are supposed to be? I informed the project manager that the egress needs to follow the natural traffic pattern. I was curious about the different flow patterns of the doors so I researched the code but was unable to locate anything in the code regarding whether it was code or not, except for the AHJ. The county where I live also agreed with me but if someone out there knows if this is code please respond. Sent in anonymously for discussion. Click Title to View | Submit Your Question | Subscribe A business occupancy we're working on has 550 occupants, and requires three means of egress per Section 7.4.1.2 (NFPA 101, 2018 Edition).
Section 7.5.1.1.1 indicates that egress shall be arranged such that each occupant has access to not less than two means of egress. When the three means of egress are required per Section 7.4.1.2, does access to all three means of egress need to be provided to each occupant? Or will providing access for each occupant to a minimum of two means of egress satisfy the code requirement? Sent in anonymously for discussion.

Would a rooftop access stair with floor level located at 76' warrant the requirements of a high-rise building?

Click Title to View | Submit Your Question | Subscribe We have a building that was designed with exit width and stair width per occupant using the exception CBC 1005.3.1 for a sprinklered building with EVACS (emergency voice/alarm communication system), however, the fire alarm design drawings show horns/strobes.
Found out through the fire alarm deferred submittal corrections. Changing the width of stairs and exit doors is not an option as the shell is already built. The EVACS option will cause delays, cost impacts, and material procurement challenges and not advised by FD because building has inherent ambient noise associated with building operations.

There is a building with two dwelling units above a mercantile drinking establishment of less than 50 persons.

It is a privately owned storage unit (no public access) used for the storage of exotic cars, maybe 3 vehicles in total. The space is about 1,400 square feet, and is fire sprinkler protected. There is a wood-framed mezzanine at the back of the unit as is about 300 square feet.
The question that has come up is if the underside of the open wood stairs to the mezzanine needs to be protected with fire-retardant gypsum board? There is no sprinkler coverage under the stairs. The mezzanine may be built out by the owner to have a few chairs, a couch, a television, etc. Digging into the code talks a lot about accessibility but not so much about the fire resistance requirements for the stairs. I have the found following in the 2015 IBC (code we are under): 1104.4 Multistory buildings and facilities. At least one accessible route shall connect each accessible story and mezzanine in multilevel buildings and facilities. Exceptions 1. An accessible route is NOT required to stories and mezzanines that have an aggregate area of not more than 3,000 square feet (278.7 m2) and are located above and below accessible levels. This exception shall not apply to: ...and... 4. Where a two-story building or facility has one story or mezzanine with an occupant load of five or fewer persons that does not contain public use space, that story or mezzanine shall not be required to be connected by an accessible route to the story above or below. So...the accessibility issue is covered but nothing about the rating of the stairs that I can find. Any help would be appreciated. Maybe I am not looking in the correct code section. Thank you!

I need to have a door in each wall.
The doors would have to swing opposite directions, I think, which means a double Firewall could not be used in an egress condition where doors both have to open in the direction of travel to the exit. It sounds like I need a tied or cantilevered Firewall instead of a double Firewall. Is this correct, or are there any other approaches to a door within a double Firewall?

The shelter-in-place Class 3 area of refuge is protected from interior and exterior hazards. There are vertical openings through all 4 floors. The UFC is governing.
Based on this, do the stairwells need to be intertied directly to the shelter-in-place area of refuge for an exit enclosure that is a direct accessible means of egress (we are providing accessibility provisions)? Does the shelter-in-place area need to be a smoke enclosure as well as the interconnected stairwell system? Based on this will both the stairwell and the shelter-in-place need to be pressurized to meet design intent?

Discuss This | Submit Your Question | Subscribe We have a dormitory project where, on the first floor, and entry lobby at the front entrance connects directly into a main corridor that runs the length of the dormitory. On either end of the corridor are exterior exits. There are also exit enclosures from the two upper levels that discharge to the exterior on both ends of the building. This project is under NFPA 101-2018 and is fully-sprinklered.
NFPA 101-2018 7.1.3.1 and 28.3.6 state the following: 7.1.3 Separation of Means of Egress. 7.1.3.1 Exit Access Corridors. Corridors used as exit access and serving an area having an occupant load exceeding 30 shall be separated from other parts of the building by walls having not less than a 1-hour fire resistance rating in accordance with Section 8.3, unless otherwise permitted by one of the following: (1) This requirement shall not apply to existing buildings, provided that the occupancy classification does not change. (2) This requirement shall not apply where otherwise provided in Chapters 11 through 43. Because this is a new dormitory, Chapter 28 also applies: 28.3.6 Corridors. 28.3.6.1 Walls. 28.3.6.1.1 Exit access corridor walls shall comply with 28.3.6.1.2 or 28.3.6.1.3. 28.3.6.1.2 In buildings not complying with 28.3.6.1.3, exit access corridor walls shall consist of fire barriers in accordance with Section 8.3 that have not less than a 1-hour fire resistance rating. 28.3.6.1.3 In buildings protected throughout by an approved, supervised automatic sprinkler system in accordance with 28.3.5, corridor walls shall have a minimum 1∕2-hour fire resistance rating. Our question is - is the lobby, by code, considered part of the corridor (and therefore need to be rated)? Two ways of looking at this - one is that the code is strictly only discussing requirements for the corridor and not a lobby. The other way of looking at it is that the lobby is acting as the corridor when it serves as part of the exit access for the building. Normally a 1/2-hour rating wouldn't make all that much of a difference, but there's storefront in the lobby space between an adjacent office and the lobby which would have a cost impact to the project.
