    To Prevent

    To buy time for

    escape and rescue

    To minimize

    property/life loss

  • LONDON GRENFELL TOWER (JUNE 2017)

    the use of the flammable cladding being blamed for

    spreading the fire that killed at least 70+ people.

    Barry Turner, director of technical policy at Local Authority

    Building Control, which represents council building control

    teams in England and Wales, said: What we need to

    know is what was inspected. You can go on site 16

    times but not necessarily see everything you need to see.

    They may have inspected the fixings, the fire barrier and

    the cavity, which are equally important but are useless if

    you put a flammable material on the front.

  • COMBUSTIBILITY V.S. FIRE RESISTANCE

    Non-combustibility:

    Material characteristic

    Test standard: BS 476 Part 4 Non-combustibility test

    for materials

    Limited combustibility : BS 476 Part 7 Method of test

    to determine the classification of the surface spread of

    flame of products

    Fire resistance:

    System Characteristic : openings + penetrant +

    firestop sealing

    Test standard: Linear joint: BS EN 1366-3 or

    Penetration seal: BS EN 1366-4; BS 476 Part 20.

    Materials of non-combustible DO NOT mean

    they are fire resistance within a given
