Subject: 12 IBC Section 1029 Emergency Escape and Rescue
Question 1:
Are emergency escape and rescue openings required in R-2 occupancies, where the story has more than one exit?
Answer 1:
No.
Emergency escape and rescue openings are not required in R-2 occupancies where the story has more than one exit.
Emergency escape and rescue openings are required in R-2 occupancies where the story with the single exit provision of Section 1021 is used. Even though emergency escape and rescue openings do not qualify as a means of egress / exit, they do offer a 2nd way of escape during an emergency.
Question 2:
Is the deletion of the exceptions found in the 2009 IBC Section 1029, as it appears in the 2012 IBC 1029, a direct response to the requirement that all R-2 occupancies are now required to be sprinklered so emergency escape and rescue opening are no longer required in any R-2 building with two means of egress?
Answer 2:
Yes.
Question 2:
2012 IBC Section 1029 states that in addition to the 1 exit door required from an R-2 sleeping room on the first floor, we must have emergency escape and rescue opening according to 1021.
2012 IBC Section 1021, Tables 1021.1(1) and 1021.1(2) and footnote “a”, provides the criteria for stories with a single exit and footnote “a” stipulates that “Buildings classified as Group R-2 equipped throughout with an automatic sprinkler system in accordance with Section 903.3.1.1 or 903.3.1.2 and provided with emergency escape and rescue openings in accordance with Section 1029.” can have just one means of egress from the entire story.
Therefore, the only time emergency escape and rescue openings are required is when the story has a single exit.
Is this a correct understanding of the section?
Answer 2:
Yes. See Answer to Question 1.
Question 3:
Is an interior sleeping unit, fully sprinklered, without emergency escape and rescue openings, with a maximum occupant load of 10 (complying with 1015.1 for a space with a single exit), with only one 36 inch door, opening into a corridor that is constructed in compliance with 2012 IBC and the corridor has two compliant exits allowed?
Answer 3:
Yes. See answer to Question 1.
Question 4:
Is a story containing 30 of the sleeping units as described in Question 3 allowed if the corridor and exits are the correct width for the occupant load served?
Answer 4:
Yes. See answer to Question 1.
