Adoption status of FBC 2007.

■

What is a “significant” change?

■

What are the most significant changes?

5

FBC 2007 Adoption Status

■

Was adopted by the State on March 1, 2009.

■

Florida also adopted the 2007 Florida Fire Prevention Code based on the 2006 Life Safety Code (NFPA 101).

6

Significant Changes

■

Have impact on overall building design.■

Present design challenges

■

Some changes result in more flexible design options.

■

First 10 chapters only covered in this presentation.

7

Assembly Occupancies

■

Assembly can be reclassified into Business occupancies (303.1) if:●

Buildings used for assembly purposes

with

<50 persons are classified as Group B. ●

Accessory space used for assembly purposes

<750 sq. ft. or with an occupant

load of <50 persons are classified as Group B

or part of adjoining occupancy.

8

Accessory Occupancies

■

Accessory occupancies are:●

Subsidiary to main occupancy.

●

Aggregate ≤

10% of area of the story.●

≤

and area increases.□Exceptions: Assembly areas < 750 sq. ft.;

assembly areas accessory to Group E; and accessory religious education rooms & auditoriums are not separate occupancies.

9

Mezzanines

■

Maximum floor area increased from 1/3

to ½

of area of room where located, if:●

Building is noncombustible, (I or II) sprinklered and has voice fire alarm (505.2).

■

Although still 1/3 in FFPC

10

Fire Resistance Rated Glazing

■

Fire resistant rated glazing is permitted to be used as a fire barrier.●

●

Specific marking “W-XXX”

required on the glass where “XXX”

is the fire resistance rating in minutes.

11

Elevator Lobbies■

Enclosed elevator lobbies required at each floor with fire partitions equal to the fire resistance rating of the corridor when (707.14.1): ●

Building is sprinklered and greater than 75 ft. in height, regardless of occupancy.

●

Building is unsprinklered and is greater than 3 stories.

●

Occupancy Group I-3 (detention) greater than 3 stories (sprinklered or unsprinklered).

●

Exceptions•

Street level floor with sprinklers throughout.•

Pressurized elevator hoistway (707.14.2).*** Can’t really be done!

•

When additional hoistway doors provided.

12

Enclosed Elevator Lobbies

13

Smoke Dampers In Exhaust Shafts

■

Smoke dampers no longer required at penetrations in exhaust shaft enclosures in Group R

(or B) occupancies.

●

Sub-ducts must be steel, have min. wall thickness of .019 inches, extend at least 22 inches vertically and have continuously powered fan at upper terminus of shaft (716.5.3). Standby power may be required for fan.

●

Also not required at shaft penetration where part of mechanical smoke control system, or where damper will interfere with operation of smoke control system.

14

Smoke Dampers In Exhaust Shafts

15

Sprinklers in Group A-2■

Sprinklers required when occupant load is 100 or more

(reduced from 300).●

Group A-2 includes banquet halls, restaurants and taverns (903.2.1.2).

16

Design Fire

■

The design fire is determined by analysis. (909.9)

■

No longer 5,000 BTU/S minimum.■

NFPA 2,000 BTU/S

17

Design Fire

■

Compare: 5,000 to 2,500 fire■

Maintain smoke layer at 50’

AFF

■

5,000 BTU/S = 168,000 cfm■

2,500 BTU/S = 130,000 cfm

■

Make-up air: 756 ft2

v. 585 ft2

■

171 ft2

= 7 doors

18
