CHECKLIST OF SPECIFIC CHANGES

  • Comment

5 Materials and workmanshipAllows product acceptance from European Technical Approvals, with conditions of use within terms of the certificate.

5 Independent certification schemesCertification and registration of installers and maintenance firms intended to provide confidence in the standard of workmanship provided.

6 Other regulationsReference to Workplace Regulations 1992 and Construction Regulations 1996.

11 Interaction with other legislationReferences to Fire Precautions [Workplace] Regulations 1997 (as amended 1999), with employer/occupier responsibility for continuous workplace risk assessment; to identify all potential hazards including fuel sources - both as contents and in the construction. Records of risk reduction actions will be beneficial.

13 Security and door locksIt is not appropriate to control the type of lock used on front doors to dwellings.

16 Fire alarms and fire detection systemsRevised order of information and including powered smoke alarm recommendations.

20 Escape across roofsDwellings to ensure 30 minutes fire resistance for that part of a roof, its support structure, and openings within 3m, which forms the escape route.

39 Widths of escape routesMarginally reduced by circa 50mm.

40 Cavity barriersReference to use in corridor systems.

51 External escape stairsRe-location of diagrams for clarity.

54 Shop store roomsStore rooms to be separated from retail areas unless protected by sprinklers.

63 Raised storage areasMinor amendments relating to new fire alarm provisions below raised storage areas.

64 CompartmentalisationNew guidance for buildings with atria and for special hazards.

66 Compartment floorsNew diagram 26 complements the textual guidance.

67 Maximum dimensions of building or compartment [non-residential]Relevant height of top storey floor of industrial buildings reduced from 20m to 18m.

New requirement for schools' floor areas set at 800m2. No limit for sprinklered single-storey shops, but 2000m2 limit for all unsprinklered shops. Generally no limit for other non-residentialbuildings.

There is a new statement for fire performance of trussed rafters bridging a compartment wall.

68 & 70 Junction of compartment wall with roof

Double skinned insulated roof sheeting should incorporate a band of material of limited combustibility at least 300mm wide centredover the wall.

Fire protection of roof members passing through a compartment wall, for 1500mm either side, is required to delay distortion at the junction.

69 Compartment construction in hospitalsCompartment walls and floors in hospitals (see htm81) need not be built of materials of limited combustibility if suitable sprinklers are fitted.

71 Uninsulated glazed screensTerms amended from 'glazed' screens to 'uninsulated' glazed screens.

73 - 77 Cavity barriersCavity barriers are not appropriate for use above compartment walls.

Table 13: refers to cavity barriers at the edges of cavities, including around openings.

The exceptions to the requirements for cavity barriers in Table 14 have been amended to include (e) underfloor service voids [although there may be ambiguity with (d) combustibles under the floor via openings].

79 Protection of openingsDeletion of 'integrity and insulation' from 11.2

82 Car parksA current statement that reads, 'there is some evidence that fire spread is not likely to occur between one vehicle and another', has been omitted.

86 External walls /portal framesThere are three new Notes with comments provided.

87 External walls / external surfacesBRE Fire Note 9: 'Test Method for Assessing the Fire Performance of External Cladding Systems' offered as an option to normal Class O requirements.

95 Roof coverings and rooflightsNot a change, but a point often forgotten: rooflights must be at least 3m apart and the surrounding roof covering to be a material of limited combustibility for at least 3m distance.

99+ Facilities for fire serviceHeight of floors in top storey has been increased from 9m to 11m.

Vehicle turning circles have been introduced to avoid reversing more than 20m.

Dispensation for floors above 7.5m from 600 to 900 sq.m. before firefighting shafts are installed. New references to BS 5588 are made.

Dispensations on protected lobbies for blocks of flats / maisonettes are added.

New requirements for roller shutters to be opened and closed manually.

109 - 119 Appendix A Performance of materials and structuresReference to fire resistance of timber floors, bre 208(1988), has been deleted and replaced with bre 128(1988) for structural elements.

Table A1: 60 minutes requirement for floors between shops and flats above. All criteria from below and 30-minute integrity of external walls adjacent to an external escape route.

Enclosures for service shafts and communal areas in sheltered housing deleted.

Thirty minutes fr from each side separately for places of special fire hazard, walls between store rooms and sales areas in shops and 30 minutes fr all criteria for corridor / cavity barrier subdivisions.

117 Table A5'Pitched Roofs Covered with Bitumen Felt' has been deleted and Part 1 and 3 guidance amended.

120 Appendix B - Fire doorsLimits the proportion of fire doors in compartment walls at 25 per cent.

New note on closure devices for roller doors (see page 99) and for fire doors with non-metallic leaves.

121 Table B1New item 2d for protected shafts forming a lift or service shaft in a compartment wall, and also 5c. 'Doors for enclosures to communal areas in sheltered housing' has been deleted.
