Edmonton Fire

Nature of Technical

Changes (Spatial Separation)

19

Limiting Distance (LD)Spatial Separation

• Clarification of the relationship between fire

department response time and Limiting Distance

(LD) – between buildings and also to property lines;

– 10-min response time

– Harmonization between Part 3 and Part 9 language on LD

when the 10-min is exceeded

– The 10-min response has been a requirement

for Part 3 buildings in previous editions of the NBC

20


21

Property Line

Limiting Distance (LD)


• LD values indicated in the Code provisions must be doubled on

site where:

• 10-min fire department response can not be met in 90% of

calls to the building

• any storey in the building is not sprinklered

22

LD x 2

Area of Unprotected

Openings (Spatial Separation)

– Limits on individual unprotected openings where the LD is 2 m or less;

– Area = 0.24 [(2 * LD) – 1.2]2

(Part 9 Differences)

Buildings:

– Exception for openable bedroom or sleeping room

windows having an unobstructed area equal to 0.35 m2

– Individual unprotected openings

Dwellings or homes:

... individual glazed openings or group of glazed openings in

exposing building face not exceed 50% max. allowable

For more information regarding bedroom egress windows

see Advisory #2 – Egress Windows or Doors for Bedrooms

../../Advisories/Advisory #2.PDF

Area of Unprotected


• Horizontal and vertical distances between individual

unprotected openings:

– 2 m horizontally of another unprotected opening that is on

the same exposing building face and serves the single room

or space, or

– 2 m vertically of another unprotected opening that serves the

single room or space, or another room or space on the same

storey with a separation wall that is less than 1.5m.

Fire and Smoke Alarms

Fire Protection–Fire Alarm System

Resolved Technical Differences

between Part 9 and Part 3

45


Use and Egress–Smoke Alarm

Smoke Alarm shall be

installed in every bedroom

• Fires in sleeping rooms

are the second highest

causes of fire deaths

46



• Smoke Alarm shall

meet the temporal pattern– improve audibility and

early detection

47



• Smoke Alarm

shall minimize

potential tampering

with smoke alarm (silencing)

48

• Plenum Cables



• NFC

49

Exit SignsUse and Egress

• Exit Signs

– green pictograms

conforming to ISO

standards

– conform to universal sign

– language independent

– internationally recognized

– harmonizing

internationally

50

Exit SignsUse and Egress

• Exit Signs

– Recognizing that

photoluminescent technology

• continues to function when

building emergency power fails

• provides options to designers

and easier installation,

– All exit signs need to be listed

52

Combustible Penetration New definitions

Fire stop:

• a system comprised of material, component

and means of support, used to fill gaps

between fire separations, to fill gaps

between fire separations and other

assemblies, or used around items which

wholly or partially penetrate fire separation.

53

Combustible PenetrationFire Stop

54

Combustible Penetration New definitions

Fire block:

• a material, component

or system installed in a

concealed space in a building

to restrict the spread of fire within

that concealed space, or from that

concealed space to an adjacent space.

55

Combustible PenetrationFire Block

Fire Block at wall56

Combustible PenetrationFire Protection–Penetrations through Fire

Separation

• Properly identify systems

– new definitions (fire block/fire stop)

• Clarifications

– how F- and FT-rating apply to fire stopping

– generalize explanation of “cast-in-place”

– sprinklers are exempted from having to be fire-stopped

• Penetrations in fire separation without FRR shall be smoke tight

• Relaxation:

– allow larger diameter combustible piping to penetrate a rated

assembly

57

Combustible PenetrationPenetrations

• Penetration of Wires/Cables and

Outlet Boxes– Single conductor metal sheathed

cables > 25 mm can penetrate if:

• not grouped

• separated 300 mm

58

Combustible PenetrationPenetrations by Water Closet

Combustible Piping PenetrationsCombustible drain piping is permitted to

penetrate a horizontal fire separation

provided it leads directly from a noncombustible

water closet through a concrete floor slab.

Therefore a combustible water closet drain is no

longer permitted unless a “Fire Stop” System is used

59

Combustible PenetrationPenetrations

• Through a Fire Separation it requires

F rating = rating of closures

• Through a Firewall it requires

FT rating = rating of Firewall

60

61

Plenum Cables

• Buildings of Noncombustible

Construction– Plenum cables FT-6 rating

• Buildings of Combustible Construction– Plenum Cables FT-4 rating

62

Plenum Cables

Exceptions cables and wires used for:– signals for fire alarm

– security

– radio

– television

63

Fire ProtectionPlenum Cables and Wires

– Proliferation of cables and wires

– Combustible construction:

• FT-4 rating

– Noncombustible construction:

• FT-6 rating, or

• FT-4 rating when enclosed in

noncombustible raceways.

Difference between FT-6 and FT-4:FT-6 rated cable has limited smoke development characteristics

Stairs, Ramps, Handrails

and GuardsGeneral

• Rationale

– Resolve Differences Between Parts 3 & 9 Buildings

• Changes

– Clarification as to where to measure

• height over stairs & tolerances

– Harmonize Rise and Run Dimensions

For more information about Stairs, Ramps, Handrails and

Guards, see our Advisories #1, #4 & #5 at: http://www.community.gov.yk.ca/buildingsafety/building_inspections.

Stairs, Ramps, Handrails

and GuardsLandings in Garages

2005 NBC

• Landings were required at the top of stairs in

attached garages

2010 NBC

• Requirements that apply to stairs, ramps, handrails and guards within dwelling units also now applies to stairs, ramps, handrails and guards within an attached garages.

• Landings are not required at the top of stairs in attached garages where the door opens away from the stairs, regardless of the number of risers.

67





• Exit Signs


• Plenum Cables



• NFC

68

Secondary SuitesRationale

2005 NBC (duplex/semi)

• –too onerous

• –too costly

• –not uniform across Canada

2010 NBC

Intent is provincial harmonization

• –limit the size of secondary suites

• –relax fire separation requirements

• –add concept of "secondary suite"

throughout Part 9

• –addresses fire separation, smoke

tightness, sound and ventilation

69

Secondary SuitesApproach

Requirements for Secondary

Suites were determined based on

5 principles:

• requirements for single dwelling

units are adequate for houses

with Secondary Suites

• reduction in performance

acceptable

– trade-offs

– no change required

– increase in performance

required

Intent was to:• accommodate the construction

of Secondary Suites at a

reasonable cost

• not compromising the health &

safety of ALL the occupants

70

– single real estate entity

– located in a building or portion

of a building of residential occ.

1

Secondary SuitesDefinition

– A Secondary Suite is a

dwelling unit …

– not more than two dwelling units. . . and common spaces

2

– where there are two dwelling

units, one is a Secondary Suite

2– with a prescribed floor area

80% of andmax = 80 m²

71

Secondary SuitesAppendix Note

• Secondary Suites:

– are typically created within an existing dwelling

unit, commonly called a “house”

– may have more than one storey, be on the same

level as the principal suite in the house or be above

or below the principal suite in the house

– may include individual detached houses, semi-

detached houses and freehold row houses

NBC Appendix A-1.4.1.2.(1) Defined Terms for Secondary Suite

72


Secondary SuitesFirewall Exception

Party Walls on Property Line

between Houses with Secondary Suites– A party wall does not have to be a firewall,

provided it is constructed as a fire separation (1 h FRR)

where the party wall separates:• two dwelling units with no dwelling unit above another,

• a dwelling unit and one house with a Secondary Suite and their

common spaces, or

• two houses with Secondary Suites and their common spaces

– In buildings with more than 2 houses, a party walls shall be

constructed as a firewall to create separate buildings,

each having not more than two adjacent houses with a Secondary

Suite.

73

Major ChangesSubjects




• Exit Signs


• Plenum Cables



• NFC

74

National Fire CodeConstruction and Demolition

Sites

• Fire losses on construction sites

are 6 times greater than for

completed buildings

• Expand scope of Code

to require protection

of adjacent buildings and facilities

• Request active and/or passive

fire protection systems for adjacent

buildings and facilities exposed to

fire originating from construction

and demolition sites.

– e.g. water curtains, gypsum

sheathing, temporary fire

barrier, fire watch, etc.

75

National Fire CodeInside Building Storage Tanks

for Combustible Liquids

• 2005 NFC does not apply to CSA-B139 appliances

• 2010 NFC now references CSA-B139 – limits maximum tank size

to 2500 L (5000 L aggregate)

– refers to NFC

• Storage tanks inside buildings are now

permitted in all occupancies where

combustible liquids are stored and

used as fuel for – Oil-burning equipment,

– Emergency generators, and

– Fire pumps.

76

• Current Table applies to industrial occupancies only

• New table lists maximum quantity of combustible liquids allowed

in a storage room for all occupancies.

– Storage room needs to be protected by a fire suppression

system.

• Required storage tank construction varies based on their

capacity:

– Double-walled construction ( 2500 L and 20 000 L), or

– Protected tank assembly in conformance with ULC-S655

standard (> 20 000 L).

• Monitoring of the secondary containment for leakage

National Fire CodeInside Building Storage Tanks

for Combustible Liquids

77

National Fire CodeOutside Storage Tanks–flammable

and combustible liquids

• Increased demand

dictates increased capacity

• Facilitate delivery in remote areas

• Increased capacity at fuel-dispensing

stations for aboveground storage tanks

– Individual from 50 000 to

80 000 L, and

– Aggregate from 150 000 to

200 000 L.

• Compartmentalized storage tanks now

treated as one tank to evaluate their capacity.

78

• double-walled construction

– becoming good practice

– reduced costs (savings for leak detection)

Harmonization across Canada, as in Yukon, ALL

underground storage tanks and ALL underground

piping is now required to be double-walled

construction complete with sumps for inspection &

monitoring reasons.

New requirements &

new definition for:

– Dispenser sump,

– Turbine sump.

– Spill containment sump, and

– Transition sump.

National Fire CodeOutside Storage Tanks–flammable

and combustible liquids

79

National Fire CodeRelocation and Cross-Referencing

• Relocate “building design” requirements from the NFC into the

NBC,

• Introduce cross-references in the NFC to new NBC provisions

to maintain their applicability to existing buildings, and

• Create new Sections in the NBC to accommodate requirements

from the NFC that cannot be incorporated in the existing NBC

structure.
