21 Fire and Smoke Alarms Fire Protection Fire Alarm System Resolved Technical Differences between Part 9 and Part 3 21

22 Fire and Smoke Alarms Use and Egress Smoke Alarm Smoke Alarm shall be installed in bedrooms Fires in sleeping rooms are the second highest causes of fire deaths 22

23 Fire and Smoke Alarms Use and Egress Smoke Alarm Smoke Alarm shall meet the temporal pattern improve audibility and early detection 23

24 Fire and Smoke Alarms Use and Egress Smoke Alarm Smoke Alarm shall minimize potential tampering with smoke alarm (silencing) 24

25 Spatial Separation Residential Care Facilities Fire and Smoke Alarms Exit Signs Major Changes Subject Combustible Penetration (Fire Stop, Fire Block) Plenum Cables Stairs, Ramps, Handrails and Guards (Part 3) Secondary Suites NFC What s Coming 25

26 Exit Signs green pictograms conforming to ISO standards conform to universal sign language independent internationally recognized harmonizing internationally Exit Signs Use and Egress 26

27 Exit Signs Use 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 27

28 Spatial Separation Residential Care Facilities Fire and Smoke Alarms Exit Signs Major Changes Subject Combustible Penetration (Fire Stop, Fire Block) Plenum Cables Stairs, Ramps, Handrails and Guards (Part 3) Secondary Suites NFC What s Coming 28

29 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. 29

30 Combustible Penetration Fire Block Fire Block 30

31 Fire block: Combustible Penetration New definitions 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. 31

32 Combustible Penetration Fire 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 32

33 Combustible Penetration Penetrations Penetration of Wires/Cables and Outlet Boxes Single conductor metal sheathed cables > 25 mm can penetrate if: not grouped separated 300 mm 33

34 Combustible Penetration Penetrations by Water Closet Combustible Piping Penetrations Combustible drain piping is permitted to penetrate a horizontal fire separation provided it leads directly from a noncombustible water closet through a concrete floor slab. 34

35 Combustible Penetration Penetrations Through Fire Separation requires F rating = rating of closures Through Firewall requires FT rating = rating of Firewall 35

37 Plenum Cables Buildings of Noncombustible Construction Plenum cables FT-6 rating Buildings of Combustible Construction Plenum Cables FT-4 rating 37

38 Plenum Cables Exceptions cables and wires used for: signals for fire alarm security radio television 38

39 Fire Protection Plenum 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: Limited smoke development for FT-6 39

43 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 National Fire Code Construction and Demolition Sites 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. 43

44 National Fire Code Inside Building Storage Tanks for Combustible Liquids 2005 NFC does not apply to CSA-B139 appliances 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. 44

45 National Fire Code Inside Building Storage Tanks for Combustible Liquids 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 L), or Protected tank assembly in conformance with ULC-S655 standard (> L). Monitoring of the secondary containment for leakage 45

46 Increased demand dictates increased capacity Facilitate delivery in remote areas Increased capacity at fuel-dispensing stations for aboveground storage tanks : Individual from to L, and Aggregate from to L. Compartmentalized storage tanks now treated as one tank to evaluate their capacity. National Fire Code Outside Storage Tanks flammable and combustible liquids 46

47 double-walled construction becoming good practice reduced costs (savings for leak detection) National Fire Code Outside Storage Tanks flammable and combustible liquids Underground storage tanks and piping now required to be double-walled construction. New requirements and new definition for: Dispenser sump, Turbine sump. Spill containment sump, and Transition sump. 47

48 National Fire Code Relocation 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. 48
