PART B REVISED  APRIL 2007

Section 7: Protection of openings and fire-stopping

7.2
 “ If a fire separating element is to be effective, then every joint, or imperfection of fit, or opening to allow services to pass through the element, should be adequately protected by sealing or fire-stopping so that the fire resistance of the element is not impaired”

7.4
“ Consideration should also be given to the effect of services that may be built into the construction that could adversely affect its fire resistance. For instance, where downlighters, loudspeakers or other electrical accessories are installed, additional protection may be required to maintain the integrity of a wall or floor”.

7.14
“ Guidance on the process, installation and maintenance of passive fire protection is available in Ensuring Best Practice for Passive Fire Protection in
Buildings (ISBN: 1 87040 919 1) produced by the Association for Specialist Fire Protection (ASFP)”

Section 12 Ceilings
“The fire resisting ceiling selected, should have documented test evidence to show that it meets the appropriate level of fire resistance for the relevant application and should be designed, specified and constructed to fully satisfy the manufacturers instructions.

Lighting fittings, and other penetrations through the ceiling, must also have the same demonstrated standard of fire resistance, and be appropriate for the type of ceiling.”)

The IEE Wiring Regulations 16th Edition BS 7671:2001 Section 527-02-01 says:“Where a wiring system passes through elements of building construction such as floors, walls, roofs, ceilings, partitions or cavity barriers, the openings remaining after the passage of the wiring system shall be sealed according to the degree of fire resistance of the element concerned (if any).”

Part P. Regulations 4 (2) states that, on completion of work, the building should be no worse in terms of the level of compliance with other applicable Parts of Schedule 1. These may include, but are not limited to, Parts B, E, F and J., For example, one or more perforations of a ceiling lining beneath a floor - made to accommodate recessed lighting or similar fittings - may have an adverse effect on that floors performance in terms of its resistance to fire and sound penetration. Due regard should therefore be paid to the guidance in Approved Document B (Fire Safety) on the performance of fire resisting and compartment floors, and Approved Document E (Resistance to the passage of sound).

All down lighters must be fitted by an installer that is registered by an approved Part P scheme or alternatively, this new electrical work must be notified to and inspected by your local Building Control Officer.

Snaplite recessed down lighters, have successfully completed the following test programme, and fitting Snaplite gives immediate compliance with Building Regulations B, E, and P, without the need for covers or other external protection methods. These tests included modern I beam and metal web joist structures, in addition to traditional floor structures.

A CD is available with 146 pages detailing the above tests and their results. Please call 01527 595 349 for your copy.
