DEFINITIONS

Definitions

5

Definitions202. Exit, Horizontal. A path of egress travel from one building to an area in another building on approximately the same level, or a path of egress travel through or around a wall or partition to an area on approximately the same level in the same building, which affords safety from fire and smoke from the area of incidence and areas communicating therewith.

Absolutely the dumbest definition/description of an extremely important component of a means of egress system.

Through or around a wall or partition? Really? What does that mean? Therewith? Who talks like that?

A source of confusion for decades.

9

Definitions (cont.)

The new definition for a horizontal exit:

202. Horizontal Exit. An exit component consisting of fire-resistance-rated construction and opening protectives intended to compartmentalize portions of a building thereby creating refuge areas that afford safety from the fire and smoke from the area of fire origin.

Special Detailed Requirements Based on Use and Occupancy

BUILDING PLANNING

Special Detailed Requirements

404. Atriums

13

Atriums

404.5 Smoke control. A smoke control system shall be installed in accordance with Section 909.

Exception: In other than Group I-2 and R-2.1, smoke control is not required for atriums that connect only two stories.

Oops! What now?

A two-story atrium in a hospital will require smoke control, or it must be separated from the Group I-2 by an occupancy separation.

This change deletes Group I-2 and R-2.1 from the smoke control exception for two-story atriums. For Group I-2 and R-2.1, the revision reverts back to the 2001 California Building Code requirement based on the 1997 Uniform Building Code.

14

8

Group I-2 — Corridors407.2.1 Waiting and similar areas. Waiting areas and similar spaces constructed as required for corridors shall be permitted to be open to a corridor, only where all of the following criteria are met:

1. The spaces are not occupied as care recipients’ sleeping rooms, treatment rooms, incidental uses listed in Table 509 or hazardous uses.

2. The open space is protected by an automatic smoke detection system installed in accordance with Section 907.

3. The corridors onto which the spaces open, in the same smoke compartment, are protected by an automatic smoke detection system installed in accordance with Section 907, and the smoke compartment in which the spaces are located is equipped throughout with quick-response sprinklers in accordance with Section 903.3.2.

15

Group I-2 — Corridors (cont.)

International Building Code (IBC): While not the intent

of the IBC, fire sprinklers can be considered fire detectors.

California Building Code (CBC): To avoid confusion, State Fire Marshal (SFM)

identifies required detection as smoke detection.

16

9


Belts and suspenders?

The IBC requires fire detection in the corridor or fire sprinklers throughout the smoke compartment.

The CBC (SFM) requires both smoke detection in the corridor and fire sprinklers throughout the smoke compartment.

17


Belts and suspenders? No. Two very different functions.

Fire control Early warning

18

10


407.2.1 Waiting and similar areas (open to a corridor, cont.)

4. The space is arranged so as not to obstruct access to the required exits.

5. Each space is located to permit direct visual supervision by the facility staff.

19

Group I-2 — Nursing Homes

Household Model Nursing Home:

11

Group I-2 — Nursing Homes

407.2.5 Nursing home housing units

The 2015 International Building Code adopts additional allowances applicable only to nursing homes permitting shared living spaces, group meeting areas or multipurpose therapeutic spaces in areas open to corridor systems (known as the household model). These provisions are further amended by the State Fire Marshal in the California Building Code.

21

Group I-2 — Nursing Homes (cont.)

22Group I-2 shared living space

12


407.2.5 Nursing home housing units. In Group I-2, Condition 1,occupancies, in areas where nursing home residents are housed, shared living spaces, group meeting or multipurpose therapeutic spaces, shall be permitted to be open to the corridor, where all of the following criteria are met:

1. The walls and ceilings of the space are constructed as required for corridors.

2. The spaces are not occupied as resident sleeping rooms, treatment rooms, incidental uses in accordance with Section 509, or hazardous uses.

3. The open space is protected by an automatic smoke detection system installed in accordance with Section 907.

23

The 2015 IBC identifies two conditions for Group I-2. These conditions (Condition 1 and Condition 2) identify different levels of nursing and medical care. Condition 1 describes nursing homes. Condition 2 pertains to hospitals.

The State Fire Marshal does not adopt these conditions.

When enforcing fire life safety provisions, the State Fire Marshal does adopt specific requirements related to householdmodel nursing homes. These requirements are found in CBC Sections 407.2.5 and 407.2.6.

24


13


407.2.5 Nursing home housing units (cont.)

4. The corridors onto which the spaces open, in the same smoke compartment, are protected by an automatic smoke detection system installed in accordance with Section 907, and the smoke compartment in which the spaces are located is equipped throughout with quick-response sprinklers in accordance with Section 903.3.2.

5. The space is arranged so as not to obstruct access to the required exits.

6. Each space is located to permit direct visual supervision by the facility staff.

25

Group I-2 — Nursing Homes (cont.)407.2.6 Nursing home cooking facilities

The 2015 IBC adopts additional allowances applicable only to nursing homes permitting cooking facilities open to corridor systems. These provisions are amended by the State Fire Marshal in the CBC.

26

14


Domestic cooking facility. Adopted by SFM, but with amendments.

27

Separation required


407.2.6 Nursing home cooking facilities. In Group I-2, Condition 1,occupancies, rooms or spaces that contain a cooking facility with domestic cooking appliances shall be permitted in fully sprinkleredbuildings where all of the following criteria are met:

1. The number of care recipients housed in the smoke compartment is not greater than 30.

2. The number of care recipients served by the cooking facility is not greater than 30.

3. Only one cooking facility area is permitted in a smoke compartment.

28

15

Group I-2 — Nursing Homes (cont.)407.2.6 Nursing home cooking facilities (cont.)

4. The types of domestic cooking appliances permitted are limited to ovens, cooktops, ranges, warmers and microwaves.

5. A domestic cooking range hood installed and constructed in accordance with the California Mechanical Code is provided over the cooktop or range.

29


407.2.6 Nursing home cooking facilities (cont.)

6. A portable fire extinguisher shall be installed in accordance with Section 906 of the California Fire Code.

30

16


The IBC contains additional requirements pertaining to the arrangement of domestic cooking appliances in areas open to the corridor, including:

• The installation of UL300A extinguishing systems• The interconnection of the extinguishing system to fuel and

electrical shutoffs• A remote location for shutoff of fuel and power• A timer that automatically shuts off the cooking appliances

within 120 minutes

Rather than imposing these additional installation requirements, the CBC (SFM) requires that these facilities be separated from the corridor.

31

Group I-2 — Care Suites

32

17

Group I-2 — Care Suites

407.4.4.5 Care suites containing sleeping room areas 407.4.4.5.1 Area. Care suites containing sleeping rooms shall be not greater than 5,000 square feet in area.

Exceptions:1. Care suites containing sleeping rooms shall be permitted to be not

greater than 7,500 square feet in area where an automatic fire sprinkler system is provided throughout the Group I-2 fire area.

2. Care suites containing sleeping rooms shall be permitted to be not greater than 10,000 square feet in area where an automatic fire sprinkler system is provided throughout the Group I-2 fire area and where an automatic smoke detection system is provided throughout the care suite and installed in accordance with Section 907.

33

Group I-2 — Care Suites (cont.)

Where a Group I-2 care suite containing sleeping rooms is located in a fire area protected by fire sprinklers, the suite is now permitted to be 7,500 sq. ft.

Where both sprinklers and smoke detection are provided, these suites can now be 10,000 sq. ft.

34

18


407.4.4.5.3 Travel distance. The travel distance between any point in a care suite containing sleeping rooms and an exit access door from that care suite shall be not greater than 100 feet.

This is not a change from the 2013 CBC; however, it was omitted from the IBC and is inserted here as an amendment to the 2016 CBC. This requirement is consistent with National Fire Protection Association (NFPA) 101-2012, Section 18.2.5.7.2.4(A).

35


407.4.4.6.1 Area. Care suites of rooms, other than sleeping rooms, shall have an area not greater than 10,000 square feet.

The IBC was revised to permit care suites of rooms, other than sleeping rooms, to have an allowable area of 12,500 sq. ft. and 15,000 sq. ft. where a smoke detection system is provided in the suite. These increases, however, are not permitted by NFPA101-2012, Section 18.2.5.7.3.3. The CBC is amended to continue the requirement for a floor area of not more than 10,000 sq. ft. for these suites. This avoids a conflict with NFPA 101-2012, The Life Safety Code®.

36

19


407.4.4.6.2 Exit access. Any room or care suite, other than sleeping rooms, with an area of more than 2,500 square feet shall have no fewer than two exit access doors from the room or care suite located in accordance with Section 1007.1.

Any room or care suite with an area greater than 2,500 sq. ft. requires at least two exit access doors. 2015 IBC language contained the requirement for care suites, but omitted the requirement for rooms. This is also a requirement of NFPA101-2012, Section 18.2.5.5.2.

37


407.4.3 Reserved

This section of the 2015 IBC adopts additional allowances applicable only to nursing homes that permit furniture located within corridor systems. These provisions are not adopted by the CBC.

These provisions conflict with the requirements of the State Fire Marshal contained in Title 19, CCR, Section 3.11.

38

20

Group I-2 — Smoke Barriers407.5 Smoke barriers. Smoke barriers shall be provided to subdivide every story used by persons receiving care, treatment or sleeping, and to divide other stories with an occupant load of 50 or more persons, regardless of occupancy or use, into no fewer than two smoke compartments.

A source of some confusion, it is now clearly stated that smoke barrier requirements are a concern on stories that are not necessarily used for patient care, treatment or sleeping, or otherwise classified as a Group I-2 occupancy.

This is consistent with requirements of NFPA 101-2012, The Life Safety Code®.

39

Group I-2 — Smoke Barriers (cont.)

407.5 Smoke barriers (cont.)

Such stories shall be divided into smoke compartments with an area of not more than 22,500 square feet in Group I-2, Condition 1, and not more than 40,000 square feet in Group I-2, Condition 2, and the distance of travel from any point in a smoke compartment to a smoke barrier door shall be not greater than 200 feet. The smoke barrier shall be in accordance with Section 709.

The 2015 IBC increased the maximum floor area of smoke compartments in hospitals from 22,500 square feet to 40,000 square feet. In NFPA 101-2012, The Life Safety Code®, the maximum area of a smoke compartment is 22,500 square feet. To avoid a conflict, the increase in floor area is not adopted.

40

21


407.5 Smoke barriers

The maximum area for smoke compartments in all Group I-2 occupancies remains 22,500 square feet.

41

22,500 sq. ft.



Exceptions:3. This requirement shall not apply to

the following:

3.1 Any story, not containing a Group I-2 or I-2.1 occupancy, that is located above a story containing a Group I-2 or I-2.1 occupancy.

42

22


Exceptions (cont.):3.2. Areas that do not contain a Group I-2 or I-2.1 occupancy, where such

areas are separated from the Group I-2 or I-2.1 occupancy by a horizontal exit in accordance with Section 1025.2.

43


Exceptions (cont.):3.3. Any story, not containing a

Group I-2 or I-2.1 occupancy, that is located more than one story below a story containing a Group I-2 or I-2.1 occupancy.

44

23


Exceptions (cont.):3.4. Any story housing only

mechanical equipment where such story is located below a story containing a Group I-2 or I-2.1 occupancy and is separated from the story above by a horizontal assembly having not less than a 2-hour fire-resistance rating.

45



The new Exception 3, with its four subsections, further clarifies that there are specific conditions under which a smoke barrier is not required on other floors or in other areas that are not Group I-2 or Group I-2.1 and are not used for patient care, treatment or sleeping.

This exception is consistent with NFPA 101-2012, the Life Safety Code®, Section 18.3.7.2.

General Building Height and

Area Limitations

BUILDING PLANNING

General Building Height & Area

503.1 General. Unless otherwise specifically modified in Chapter 4 and this chapter, building height, number of stories and building area shall not exceed the limits specified in Sections 504 and 506 based on the type of construction as determined by Section 602 and the occupancies as determined by Section 302 except as modified hereafter. Building height, number of stories and building area provisions shall be applied independently. Each portion of a building separated by one or more fire walls complying with Section 706 shall be considered to be a separate building.

Introduction to the reformatting of the building height and area tables.

48

25

General Building Height & Area (cont.)

What is happening here?

This is big news.

Table 503 is retired.

It has been replaced by three new tables that separate general building limitations into allowable height, allowable number of stories and allowable area, each of which must be applied independently.

49


50

504.3 Height in feet. The maximum height, in feet, of a building shall not exceed the limits specified in Table 504.3.

Sprinkler increase is now included in table information.

26


504.4 Number of stories. The maximum number of stories of a building shall not exceed the limits specified in Table 504.4.

51

Sprinkler increase is now included in table information.


For SFM-regulated occupancies, SFM adds (without area increase) to sprinkler information in tables to clarify double dipping is not permitted.

SFM-regulated occupancies: A, E, H, I, L, R and High Rise.

52

27

General Building Height & Area (cont.)506.2 Allowable area determination. The allowable area of a building shall be determined in accordance with the applicable provisions of Sections 506.2.1 through 506.2.4 and Section 506.3.

53

TABLE 506.2a,b,n

NS: Nonsprinklered S1: Sprinklered One Story SM: Sprinklered Multistoried


For SFM-regulated occupancies, SFM adds (without height increase) to sprinkler information in table to clarify double dipping is not permitted.

54

28

Separation of Occupancies

e. [SFM] Group I and F-1 occupancies and Group R-2.1 and F-1 occupancies shall have a 3-hour separation.

f. [SFM] Commercial kitchens not associated with cafeterias and similar dining facilities in Group I-2 and Group R-2.1 shall have a 2-hour separation and shall be protected by an automatic sprinkler system.

55

Separation of Occupancies (cont.)

What just happened here?

Model Code provisions of Table 508.4 require a 2-hour separation between Group I-2 and Group F-1.

SFM amendment (footnote e) requires a 3-hour separation between Group I-2 and Group F-1.

2015 Model Code revision classifies a separate commercial kitchen >2,500 sq. ft. as a Group F-1.

SFM amendment (footnote f) permits a 2-hour separation between commercial kitchen in Group I-2.

705.2.3 Combustible projections. Combustible projections extending to within 5 feet of the line used to determine the fire separation distance shall be of not less than 1-hour fire-resistance-rated construction, Type IV construction, fire-retardant-treated wood or as required by Section 1406.3.

Exception: Type VB construction shall be allowed for combustible projections in Group R-3 and U occupancies with a fire separation distance greater than or equal to 5 feet.

Language has been deleted simplifying the requirements.

64

33

Projections (cont.)

705.2.3 Combustible projections

Previously, three separate thresholds were established to identify the scope of the requirement. Where any one of the three thresholds was exceeded, the limitations on combustible projections would apply. As a result, the most restrictive condition was always applied. With the revision, only the 5-foot fire separation distance threshold is now the controlling point for where the additional protection requirements apply.

Fire Wall Stability

706.2 Structural stability. Fire walls shall be designed and constructed to allow collapse of the structure on either side without collapse of the wall under fire conditions. Fire walls designed andconstructed in accordance with NFPA 221 shall be deemed to comply with this section.

67

Fire Wall Stability (cont.)

706.2 Structural Stability

CBC no longer points to using only double fire walls. NFPA 221 includes additional criteria for tied walls (example) or cantilever fire walls (not so common).

68

35

Smoke Barrier Walls

709. Smoke Barriers

709.4.1 Smoke-barrier walls separating smoke compartments. Smoke-barrier walls used to separate smoke compartments shall form an effective membrane continuous from outside wall to outside wall.

Really? Well not exactly.

69

Smoke Barrier Walls (cont.) From the IBC 2015 Code and Commentary:

Unintended consequences: Reformatting now forces smoke compartments to be formed with walls that must continue to the outside wall. Therefore, although the basic intent of smoke compartments is to form two completely separated spaces where smoke does not spread from one to the other, the text requires that the floor level must be divided from outside wall to outside wall, even though allowing a smoke barrier to terminate at another smoke barrier or back to itself may also create two adequately separated compartments.

70

36

Smoke Barrier Walls (cont.)

From the IBC 2015 Code and Commentary:

However, it seems reasonable that the building official could still allow smoke compartments to be formed by terminating at another smoke barrier by using the alternate method provisions of Section 104.11.

Reasonable to require an alternate method to comply with the intent?

71

Smoke Barrier Walls (cont.)709.4.2 Smoke-barrier walls enclosing areas of refuge or elevator lobbies. Smoke-barrier walls used to enclose areas of refuge in accordance with Section 1009.6.4, or to enclose elevator lobbies in accordance with Section 405.4.3, 3007.6.2 or 3008.6.2, shall form an effective membrane enclosure that terminates at a fire barrier wall having a level of fire protection rating not less than 1 hour, another smoke-barrier wall or an outside wall. A smoke and draft control door assembly as specified in Section 716.5.3.1 shall not be required at each elevator hoistway door opening or at each exit doorway between an area of refuge and the exit enclosure.

Smoke Control909.4.7 Smoke control system interaction. The design shall consider the interaction effects of the operation of multiple smoke control systems for all design scenarios.

It is not uncommon for a high-rise building to contain multiple systems, such as an atrium with smoke control, pressurized stairways and hoistway pressurization used as an option for compliance with enclosed elevator lobby requirements. If these three smoke control systems are running simultaneously, they may not work as intended unless the interaction effects are evaluated during the design for all possible design fire scenarios.
