A corridor serving a one-story office building has two exits as drawn. The conference room has one door to the corridor. The building is sprinklered. The corridor has an offshoot with a dead end. What is the maximum length of the dead end portion of corridor? Use this code link to answer. - correct answersA: 50ft Search the link for "dead end" Use search when faced with a case study exam question too. Where more than one exit or exit access doorway is required, the exit access shall be arranged such that there are no dead ends in corridors more than 20 feet. So the limit for a dead end corridor is 20'. . . but wait: read on and find In occupancies in Groups B, E, F, I-1, M, R-1, S and U, where the building is equipped throughout with an automatic sprinkler system, the length of dead-end corridors shall not exceed 50 feet. We are Group B, so our dead end corridor limit for a sprinklered office building is 50ft. Dead ends are generally limited to no more than 20′ (50′ if the building is sprinklered).
