3 Originally known as When? Association of Structural Fire Protection Contractors and Manufacturers Formed in 1975

4 Why? In recognition of a need to bring together: passive fire protection (PFP) manufacturers PFP contractors testing/certification bodies to encourage, develop and give guidance on essential standards in PFP.

5 In 1996 the Association changed its name to the Association for Specialist Fire Protection To better reflect the diversity of the work being undertaken in the fields of Structural fire protection Fire stopping Fire resisting ducts and dampers Smoke extraction ducts and dampers Fire dampers Fire resisting partitions Active fire barrier curtains and other elements used for compartmentation

9 Today the ASFP is further broadening its membership and remit to reflect and respond to the significant changes and challenges that are taking place at many levels within the PFP sector Manufacturers Contractors Testing and certification bodies Tier 1 contractors and many other associate members.

10 Passive Fire Protection What is it? Built-in measures that protect the structure of the building and subdivide it into areas to limit the spread of fire and smoke.

11 Structural Fire Protection To maintain the stability of the structure during the period of the fire and ensure that it does not collapse

12 Structural steel loses about half its strength at about 500 O C.

13 Non-reactive coatings Spray or troweled on Thick Inert Sometimes hidden

14 Non-reactive board/casings Mechanically fixed Thick (10-50mm) Sometimes hidden

15 Reactive coatings Spray or brushed Thin (1-4mm)

16 The purpose of compartmentation is to: Subdivide buildings into areas of manageable risk Compartmentation

17 Subdivide buildings into areas of manageable risk Provide adequate means of escape Provide fire separation between adjacent/adjoining buildings Compartmentation The purpose of compartmentation is to: Provide access and protection for fire-fighters

30 The instructions

31 2 Case Studies City Tower London Pacific Wharf London

32 City Tower, Docklands London

33 City Tower the development Constructed in storey block of 164 Luxury Apartments Prices from 275k to 5.00m Exclusive Docklands location Finished to a high specification

34 City Tower the development City Tower is a brand new development which is situated within walking distance of Canary Wharf. This property offers stylish high specification extremelyspaciousaccommodation. FrankKnight Properties

35 City Tower the reality Many of the penetration sealing systems examined at the City Tower Development, would not be expected to achieve up to 120 minutes fire separation if they were subject to a fire resistance test Exova WarringtonCertification

36 City Tower the reality Fire stopping systems inadequately installed Fire rated wall partitions incomplete above communal area ceilings Expanded polyurethane foam extensively used as an ad hoc remedial solution No records or traceability of installation and products used

37 City Tower the reality No fire protection around services through compartment walls above ceilings

38 City Tower the reality Service penetrations through floors not sealed

39 City Tower the reality Incorrect materials used to seal around services through riser walls

40 City Tower the reality Incorrect materials used to seal around services through riser floors

41 City Tower the reality Incorrect and non-tested penetration seal solutions

42 City Tower the remedy Service penetrations correctly sealed through floors

43 City Tower the remedy Compartmentation maintained at head of party walls

44 City Tower the remedy Fire collars installed around services and head of wall sealed against concrete soffit

45 Pacific Wharf, Rotherhithe, London SE16 Constructed in Luxury Apartments Prices from 275k to 1m Exclusive Riverside location Finished to a high specification City Tower Is this a one off? Pacific Wharf is a fabulous riverside development situated on Rotherhithe Street and as such this property enjoys a peacefullocation with all the modern facilities expected from a developmentof this level Right Move

46 Pacific Wharf the reality PacificWharf is the British Leyland Austin Allegro of London Luxury Developments Richard Freeman - RTMco

47 Pacific Wharf the reality Missing Damp proof membrane Missing lintels to upper floor windows Sewage leakage in basement garage No compartmentation between properties Vertical risers without fire barriers No fire protection to structural steel Roof leaking.

48 Pacific Wharf the reality No fire barriers around high voltage cables through compartment wall in basement garage

49 Pacific Wharf the reality Service penetrations through floors not sealed

50 Pacific Wharf the reality If all else fails

51 PU Foam It says 4 hours on the tin!

52 Ensure the correct materials are used for the applications they have been tested against

53 The devil is in the detail Claimed Fire Resistance to EN Does was it says on the tin actually fit the enduse condition? Depth mm Width mm

58 Recent ASFP tests on PU foam based fire stopping Time to failure? 9 minutes!

59 Recent ASFP tests on PU foam based fire stopping Remember this? Time to failure? 7 minutes!

60 Solutions 1. Inspect everything? 2. Competent persons schemes? 3. Third party certification?

61 +ves: Fool proof Thorough -ves Very expensive Time consuming How much to do? Impossible to do all Not needed? 1. Inspect everything

62 2. Competent persons schemes The certificates My house

63 FENSA 2. My competent persons schemes 3 windows installed Part P One or more electrical circuits, alteration or addition in kitchen/ special location. Electric floor or ceiling heating system, ELV lighting CORGI (pre Gassafe) Gas boiler installed

64 3. Third Party Certification This will be dealt with by another speaker later today

65 ASFP Position on third party certification Third party certification adds value Installer certification MANDATORY for installer members ASFP always recommends the use of third party certificated products for fire protection ASFP always recommends to use of third party certificated specialist contractors for installing Passive Fire Protection.

69 ASFP On-site Guide to Fire-stopping Dos and Don ts Competency requirements of staff

70 ASFP On-site Guide to Fire-stopping Dos and Don ts Competency requirements of staff

71 ASFP Guide to Passive Fire Protection for Fire s Aimed at: Fire s Responsible Persons Those responsible for specifying/ purchasing Passive Fire Protection Being revised in 2016

72 Introduces role of Fire / Assessment Need to evaluate PFP associated with Means of escape NOT a full survey of compliance with statutory documents (ADs)

73 ½ to 3 pages on each type of Passive Fire Protection Pictures of what to look for (good & bad) Annexes with info, further reading, links to third party orgnanisations

74 The all important Check List for each type of construction Related to means of escape References to clauses in document with further information

75 What is PFP is and why needed Structural fire protection Summary - 1 Compartmentation & Means of escape Issues that cause poor installation No bar to entry to become a PFP installer Not enough inspection, enforcement or TPC for products that are invisible as installed Fixation of price and not value breaking of specification Culture of confrontation and not cooperation Poorly designed and planned work Maintenance (lack of & follow on trades) Fire stopper tools

76 Summary - 2 Examined potential solutions Total inspection Competent Persons schemes Third Party Certification (TPC) - strongest and ASFP policy NEW ASFP On-site guide to fire-stopping ASFP Guide to PFP for Fire s Passive Fire Protection is for life safety and works well if: Designed, specified and installed correctly Always use a third party certificated installer

77 PFP You only need to use it once
