Chapter 19 Building Codes & Regulations Flashcards

1
Q

**Designers are responsible for reviewing local codes, and ensuring their designs are compliant

A

Because each jurisdiction has unique requirements/amendments, designers must review to determine complete compliance for specific project

Building codes only one type of regulation affecting buildings; additional requirements may include legal/administrative regulations at state, federal, local level

**State and federal regulations

A

Most states have agencies that regulate building; in addition to building code, may enforce energy codes, environmental regulations, fabric flammability, specific rules relating to state government buildings
**STATE HAS THE POWER NOT THE GOVERNMENT!

**UL

A

Underwriters Laboratories

UL-listed labels mean a total product has passed safety test and is manufactured under

UL follow-up services program

Q

**Building codes recognize that there is no such thing as a fireproof building; there are only degrees of fire resistance. Two broad classifications of fire resistance:

A
  • Fire resistance of materials & assemblies

- Surface burning characteristics of finish materials

Q

**Materials by themselves do NOT create a fire-rated barrier; the construction assembly of which they are a part is fire-resistant. The ENTIRE assembly must be completed exactly as specified for the assembly to be considered a fire-rated barrier assembly.

Q

**Fire partition:

A

**wall assembly with 1-hr. rating used in following locations:

  • Walls separating dwelling units (apartments, dormitories, assisted living facilities)
  • Walls separating guest rooms
  • Walls separating tenant spaces in covered mall buildings
  • Corridor walls
  • ½-hour walls allowed in sprinklered buildings, a few other exceptions
  • Must provide continuous barrier, securely attached, extending continuously from floor to structure, or floor to rated ceiling with few exceptions
  • Openings must be min. ¾-hour, except corridors, which must have 20-min. assemblies
  • continuous slab-to slab partitions usually best and cheapest solution

Q

Fire barrier:

A

**fire-resistance-rated vertical or horizontal assembly designed to restrict spread of fire, confine it to limited areas, and/or afford safe passage for protected egress

**Provides more protection than fire partitions

Used for the following purposes:
-To enclose vertical exit enclosures (stairways), exit passageways, horizontal exits, and incidental use areas

  • To separate different occupancies in a mixed-occupancy situation
  • To separate single occupancies into different fire areas
  • To otherwise provide a fire barrier where specifically required by code
  • Must ALWAYS (with very few exceptions) be continuous from floor slab to underside of floor or roof slab above
  • May be required to have fire-resistance rating greater than 1-hour
  • Protection for openings in fire barriers vary from ¾-3 hours per IBC
  • Openings limited to 25% aggregate length of wall; max. opening size 120s.f.

Q

**Fire barrier opening size exceptions:

A
  • Openings can be greater than 120s.f. if adjoining fire areas equipped throughout with sprinklers
  • Fire doors serving exit enclosure can exceed opening limitations
  • If opening protective assembly has been tested per code requirements & equal or better fire rating, size not limited per opening standards.

Q

Fire wall:

A

resistance-rated wall used to separate single structure into separate construction types or provide for allowable area increases

17
Q

Smoke barrier

A

continuous vertical or horizontal membrane with min. 1-hr. rating designed to restrict movement of smoke

18
Q

IBC rates carpet; it specifically does NOT rate hard flooring, such as wood, terrazzo, vinyl, linoleum

A

True

19
Q

**Carpet rated as

A

Class I or Class II; Class I more fire-resistant

20
Q

**Textile finishes must meet one of three conditions for use:

A

Must be rated Class A per ASTM E84 & be protected by sprinklers

Must meet requirements of Method B test protocol of NFPA 265

Must meet requirements of NFPA 286
Ceiling textiles must meet ASTM E84 with sprinklers or NFPA 286

**Occupancy Groups per IBC:
A 
B  
E  
F  
H  
I  
M  
R  
S  
U
A 
A  Assembly
B  Business
E  Educational
F  Factory & Industrial
H  Hazardous
I  Institutional

22
Q

**Define Occupancy:

A

refers to type of use assigned to a building or interior space

23
Q

**Occupancy classification affects the following:

A
  • Occupancy load calculation
  • Egress design
  • Interior finish requirements
  • Use of fire partitions, fire barriers
  • Fire detection/suppression systems
  • Ventilation & sanitation requirements
  • Other special restrictions particular to a given classification
24
Q

**Accessory occupancy :

A

is space used in conjunction with main occupancy, but less than 10% of floor area of main occupancy

-Do not need separation with fire barrier

25
Q

**Incidental use area:

A

is area required to have fire separation, even though same classification as nearest main occupancy

26
Q

**Every building is classified into one of five types of construction based on fire resistance of certain building components: Types called Type I-V;

A
  • Type I most fire-resistive (most fire resistant)
  • Types I & II are noncombustible
  • Types III, IV, V are combustible (least fire resistant)
27
Q

Glass used in fire-rated partitions is divided into two types by IBC

A
  • fire-protection-rated glazing

- fire-resistance-rated glazing

28
Q

Fire-protection-rated glazing is:

A

¼” thick wired glass in steel frames or others that meet applicable requirements; must have 45-minute rating, limited to 1-hr. rated partitions & fire barriers when fire barrier is used to separate occupancies or incidental use areas

29
Q

Fire-resistance-rated glazing is:

A

glazing material meeting ASTM E119, which allows special fire-rated glazing with ratings up to 2 hours; may be used in partitions with ratings higher than 1-hour; glazing must have same rating as partition in these cases. No area limitations.

30
Q

Almost all buildings require some type of detection device, even single smoke detectors in residences

A

true

31
Q

Fire protection system:

A

fire alarm or extinguishing device/system designed to detect, control, or extinguish fire, alert occupants & fire department of fire, or any combination of these systems

Systems designed to detect:

  • Smoke or other products of combustion
  • Rise in temperature to predetermined level
  • Rate of temperature rise to predetermined rate of change
32
Q

**Guards (guardrails)

A
  • A guard is a component that prevents falls from an elevated area
  • Required along open-sided walking surfaces, mezzanines, industrial equipment platforms, stairways, ramps, landings over 30” above floor below
  • Stages and some raised platforms exceptions
  • Min. 42” high, designed so 4” sphere cannot pass through any opening up to a height of 34”
  • Must resist load of 50lb/ft. applied in any direction to top of guard
33
Q

**Mechanical systems

A

International Mechanical Code details requirements for materials, design of HVAC equipment

34
Q

**Plumbing systems

A
  • IBC specifies number of sanitary fixtures required based on occupancy
  • International Plumbing Code companion volume of IBC; gives minimum number of toilets, lavatories, drinking fountains, etc.
35
Q

**Electrical systems

A
  • IBC references NEC
  • Details requirements for materials, design of power supply, lighting systems
  • Specifies outlet locations, required GFI outlets
36
Q

**Sound ratings:

A
  • IBC requires wall, floor/ceiling assemblies in residential occupancies separating dwelling units or guest rooms from each other and from public spaces be designed/constructed to provide sound transmission control
  • Minimum STC 50 (45 if field-tested) for walls; does not apply to dwelling unit entrance doors, but these must be tight-fitting to frame & sill
  • Minimum IIC for floors must be 50 (45 if field-tested)
37
Q

**IBC and model codes do not regulate furniture flammability:

A
  • Some local/state jurisdictions do include furniture flammability standards as part of their purview
  • Standards to define limits on material’s flammability in terms of the following characteristics may apply:
  • Resistance to ignition, flame spread, smoldering, prevention of smoke development, prevention of heat contribution to growth of fire, and prevention of toxic gas release
