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.”

• Curtain wall materials shall be non-combustible, in

accordance to BS-EN 13501-1: 2007 (Class A1);

BS 476 Part 4.

• Perimeter joint shall be sealed up to form smoke

and fire barrier in accordance to BS EN 1364 Part 3

or Part 4 and BS EN 12101-1, respectively.

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

period.

For example, a piece of aluminum foil !

NON-COMBUSTIBILITY BS 476 – PART 4

• No sudden temperature rise

• Weight loss

• Total flaming time

ASTM INSPECTION STANDARD

2012 IBC (1705.16.1) Penetration firestops. Inspections of

penetration firestop system. Conducted by approved agency

in accordance with ASTM E 2741

2012 IBC (1705.16.2) Fire-resistant joint system. Conducted

by approved agency in accordance with ASTM E 2393.

FIRESTOP INSPECTION STANDARD

THE INSPECTION PROCESS

Review design documents : Method Statement

Verify materials prior to installation: Delivery Note

Verify against listed systems and/or EJ : ETA or EN test reports

Verify that ALL firestops installed : on-site FRR system installation

ASTM E2741: Standard Practice for On-Site Inspection of Installed Fire Stops

For each “type” of firestop being installed:

Witness 10% of Installations, or Destructive Testing on 2% of Installations

ASTM E2393, Standard Practice for On-Site Inspection of Installed Fire Resistive Joint Systems and Perimeter

Fire Barriers

For each “type” of fire resistive joint system being installed:

Witness 5% of linear feet being installed, or Destructive (or disassembly) testing on 1 ft. per every

500 ft.

FS Inspection 37

IF NON-COMPLIANCE IDENTIFIED

One non-compliant:

one full additional inspection of that type

10% non-compliance of one type:

inspection halted, installer re-inspects own work

Non-compliant firestop must be repaired/replaced

E2174/E2393: no guidance on what is an acceptable non-compliance percentage
