Trying to figure out terminology a bit.

assuming a single story L shaped building, where do you have to use fire doors?

Lets assume a building is shaped like an L, there is a main entrance and lobby (horizontal _ part) and a single hall (| with rooms off the hall).

The Hall (|) has an emergency exit to the outside at the top, and a fire door between it and the lobby.

off the Hall (|) there are multiple other rooms, office space (20-30 people), conference rooms, bathrooms a common area (coffee machines, ice maker)

Lets talk specifically about one of the office spaces off the Hall (|). Is a fire door needed between the Office space and the Hall?

I'm assuming that the Hall is considered the "Exit"
I'm assuming a door from an office space into the hall is an "Exit Access"
I'm assuming that the doors at the end of the hall leading to the outside and the lobby are "Exit Discharges"


Quote :
"Openings into an exit must be limited. An exit is permitted to have only those openings necessary to allow access to the exit from occupied areas of the workplace, or to the exit discharge. An opening into an exit must be protected by a self-closing fire door that remains closed or automatically closes in an emergency upon the sounding of a fire alarm or employee alarm system. Each fire door, including its frame and hardware, must be listed or approved by a nationally recognized testing laboratory. Section 1910.155(c)(3)(iv)(A) of this part defines "listed" and ยง 1910.7 of this part defines a "nationally recognized testing laboratory.""


Quote :
"An exit must be separated by fire resistant materials. Construction materials used to separate an exit from other parts of the workplace must have a one-hour fire resistance-rating if the exit connects three or fewer stories and a two-hour fire resistance-rating if the exit connects four or more stories."


Those seem to imply to me that the doors on the ends of the hall leading to the outside and the lobby both need to be fire rated.

Those also seem to imply that the office space doors on the hall should also be fire rated.

Am I missing something here?

are you changing usage or layout for the building or something?

can you post your code summary b for the building? a copy of the existing life safety plan from the last fit out?

FYI, each OSHA subsection will have definitions at the beginning:
Quote :
"Exit means that portion of an exit route that is generally separated from other areas to provide a protected way of travel to the exit discharge. An example of an exit is a two-hour fire resistance-rated enclosed stairway that leads from the fifth floor of an office building to the outside of the building.

Exit access means that portion of an exit route that leads to an exit. An example of an exit access is a corridor on the fifth floor of an office building that leads to a two-hour fire resistance-rated enclosed stairway (the Exit).

Exit discharge means the part of the exit route that leads directly outside or to a street, walkway, refuge area, public way, or open space with access to the outside. An example of an exit discharge is a door at the bottom of a two-hour fire resistance-rated enclosed stairway that discharges to a place of safety outside the building.

Exit route means a continuous and unobstructed path of exit travel from any point within a workplace to a place of safety (including refuge areas). An exit route consists of three parts: The exit access; the exit; and, the exit discharge. (An exit route includes all vertical and horizontal areas along the route.) "
