1 Firestopping for Data Cabling Dixon Tan, RCDD Specified Technologies Inc. (STI)

2 Data Cabling passing thru Fire Barrier Restore compartmentation in case of fire Compartmentation Openings for doors and cables Restore the compartmentation

3 FIRE RATED Barriers CompartmentationThe division of the building into discrete fire zones. Compartments six sided zone.

4 What is Firestopping?

5 What is Firestopping? The process of restoring back the HOURLY FIRE RESISTANCE RATING to a FIRE RATED BARRIER that has lost its rating from construction openings, joints and gaps.

6 This Is What You want

7 But Is This What You Get?

8 What do the codes require? Extract from Fire Code of the Philippines 2008 c. All penetrations of floors and walls shall be provided with firestopping having a fire resistance rating equal to that of the floor or wall.

9 International Code FireStopping Model Building Codes That Require Firestop International Building Code (IBC) Uniform Building Code (ICBO) Standard Building Code (SBCCI) National Building Code (BOCA) Life Safety Code (NFPA 101) National Electrical Code (NFPA 70) NFPA 5000 (NFPA Building Code)

10 International Code FireStopping Life Safety Code (NFPA 101) National Electrical Code (NFPA 70)

11 Fire Rating The duration for which a passive fire protection system can withstand a standard fire resistance test.

12 Where Firestopping Is Required IBC referenced test standards ASTM UL BS 476 EN Barriers E Part 6& Through Penetrati on E Part Joints E Part Perimeter Joint E

13 Where Firestopping Is Required Curtain Walls Through Penetration Joints

14 Testing Requirements Third-Party Testing To Standards F Ratings T Ratings L Ratings (Optional) Hose Stream

15 Firestopping Is Required For All Openings

23 Firestop Is Different Firestop Materials MUST expand with heat, and fill voids as cable bundle burns away but there is a minimum dose of firestop material needed to do the job

24 Intumescence = Expansion with heat

31 Challenges When it comes to maintaining the compliance of fire-resistance-rated construction in any type of building post occupancy, one of the most difficult areas is the breaches in barriers caused by datacom cabling installations.

32 The U.L. System Approach

33 U.L. Systems

34 U.L. Systems Identifying System Variables Five Groups of Variables: 1. Barrier Type 2. Hole Size 3. Penetrant Type 4. Firestop Product 5. System Rating

35 Example: Reading a UL System: Through Penetrations W-J-3158 Floor, Wall or Combination

36 The First Grouping Means: THROUGH PENETRATION FIRESTOP SYSTEMS (XHEZ) First Alpha Character signifies what is being penetrated F = Floors W = Walls C = Walls and Floors

37 Example (Cont d) Reading a UL System: Through Penetrations W-J-3158 Construction Type of Floor or Wall

38 The Second Grouping Means: THROUGH PENETRATION FIRESTOP SYSTEMS (XHEZ) Following Alpha Character(s) wall or floor construction type A = Concrete floors 5 inch thick B = Concrete floors 5 inch thick C = Framed floors D = Steel decks in marine vessels E-I = Reserved for future use J = Concrete or masonry walls 8 inch thick K = Concrete or masonry walls 8 inch thick L = Framed walls M = Bulkheads in marine vessels N-Z = Reserved for future use

39 Example (Cont d) Reading a UL System: Through Penetrations W-J-3158 Penetrant Type

40 The Third Grouping Means: THROUGH PENETRATION FIRESTOP SYSTEMS (XHEZ) Numeric Component first digit identifies the type of penetrant, next three are sequential system numbering = No Penetrant = Metallic pipe, conduit or tubing = Plastic pipe, conduit or tubing = Electrical cables = Cable trays with electrical cables = Insulated pipes = Bus ducts = HVAC ducts = Mixed multiple penetrations = Reserved for future use

43 Major Issues & Examples How do we get from here

44 Major Issues & Examples To Manageable Compliance?

45 Traditional: Cables and Sleeve With Putty

46 Major Issues & Examples The ACTUAL Life Cycle of the Average Datacom Penetration - Cables are ADDED - Firestopping is REMOVED - Until ALL we have are CABLES FIRE RATING IS GONE!

47 Major Issues & Examples 3 Key Challenges: Maintaining the seal Not overfilling Avoiding new holes

48 Major Issues & Examples A Self-Adjusting Intumescent Membrane Provides Smoke and Fire Protection 100% Of The Time, Empty or Full!

49 Major Issues & Examples Use Devices To Segregate Your Cables Or Foster Future Compliance

50 Major Issues & Examples Provide Flexibility

51 Major Issues & Examples $$$ = MAC for Cables + Reinstalled FIRESTOP + Inspection/Certification EZ-Path also has a sweet added bonus:

52 Conclusion University of the East buildings hit by fire Images from Philstar Global

53 Questions? mmm interesting Is he done yet? I want to go home

54 What s wrong with this?

55 What s wrong with this?
