Fire Doors The Role of a Fire Door

BWF-Certifire Fire Door and Doorset Scheme

Presented by John Fletcher John Fletcher Consulting Ltd.

Fire doors – main messages

1. Fire doors are essential in passive fire protection A requirement in compartmenting a building

Protecting escape routes

Save Lives – Save Property

2. Must be tested to show the design will work in a fire. What do we mean by certification?

3. Fire doors can only work correctly when . . . . Fitted with the correct compatible components for the door

Door leaf + frame / linings

Closers, Hinges and other ESSENTIAL ironmongery

Seals

Glazing

I.e. the fire door assembly / or doorset must comply with regulations

4. Where to go for help & information If in doubt - DON”T GUESS!

Industry Aims & Challenges • To improve the standard of fire doors installed in the UK

• To educate the construction industry about the importance of

third-party certification of fire doors and passive fire protection

systems

• To raise awareness and educate the consumers, and users of the

critical importance of Fire Doors

• To move the market progressively towards fire doorsets as

the best way to achieve the Scheme long-term objectives

Our Challenges

• 3 million fire doors sold per year

• Common supply route via merchants - approx 80%

• Changing the spec “to save the client money” • Cutting costs / cutting corners

• Poor understanding, poor maintenance, poor workmanship

• Fire doors are an engineered safety device – not ‘just an ordinary door’

Poor workmanship Gaps - between doors, frame-to-wall, leaf to frame

Poor workmanship & poor advice

REALLY believe

this will work in a

fire?

What are fire doors for?

What fire doors do

2. In the event of a fire • A requirement in compartmenting a

building • Protecting escape routes • Restricting initial development of a

fire. E.g restricting the amount of oxygen feeding the fire

Fire doors serve 2 purposes 1. Everyday activity • Allowing passage in and out of a

building / section of a building or a room

2 types of fire door installations

• In the UK, a fire door installation is

achieved in one of two ways:-

Doorset:

o frame, a pre-hung door leaf (with

any vision panels) and essential

ironmongery, all matched and

pre-assembled in the factory

Door Assembly:

o a fire door leaf, frame and

additional components needed to

install them, supplied and fitted

separately.

In the latter case, the components that are fitted MUST match the test

evidence. I.e. They MUST be compatible with the door leaf

Door leaf – standard practice

Fire door assembly Fire door leaf / approved frame / casing Compatible Approved Components

frame /

casing

/ lining CE marked Certifire Approved components –

Regulations

What regulations apply to fire doors?

The Building Regulations

Fire doors should have the appropriate performance - given by Test BS 476 Part 22

Classification BS EN 13501 / Test BS EN 1634 – 1/2/3

Any test evidence used to substantiate the fire

resistance rating of a door or shutter should be carefully checked to ensure that it adequately demonstrates compliance that is applicable to the complete installed assembly. Small differences in detail (such as glazing apertures, intumescent strips, door frames and ironmongery etc.) may significantly affect the rating.

Client Ownership

Handing over the correct information about the certification of

the fire door and components is extremely important for future

inspection & maintenance

Understanding certification

What does it tell us?

How do we know it’s correct or up-to-date?

Doors should be tested & certificated?

You need proof of performance Comply with building regs.

A test certificate indicates that the complete door assembly can withhold fire for a defined period of time

What many fail to realise - that the complete assembly must be installed as it was tested Components as well as door Applies to each door configuration

requires a proof

How do I know if the door is a fire door? Label Plug Proof of test evidence

What if you have none of these? then there’s a doubt about the door’s ability to perform An ‘expert’ assessment can be made

But it’s expensive

3 ways of demonstrating compliance The difference . . . .

Self declaration

“Tested to / Designed to /

Complies with BS 476 Part 22”

No guarantee that products will (or have)

reached the correct standards

May not have been tested

Was the test impartial?

What about ongoing manufacture?

Test certificate

“My product was tested.”

“I have a certificate”

Only a SNAPSHOT test

Was the test sample representative of what is ALWAYS produced?

What if manufacturing changes?

What if designs change?

What if materials change?

3rd party certification

Not only demonstrates product conformity

Audits the company’s production & product

Ensures the product is supplied to the SAME specification / design

AS TESTED

= CONFIDENCE

Uncertain? = RISK

Uncertain? = RISK

3rd party certification Warrington Certification is the UKAS test

testing of doors and components and audit

components can

be traced up or

down the supply

chain

The performance of timber doors is judged by subjecting them to the standard test procedure specified in BS 476 : Part 22: 1987 or BS EN 1634-1: 2014. Tests are made on complete door assemblies, the door and frame with all the necessary hardware.

Fire Door Certificates

What to look for . . . 1. Does the door have any identity or

marking to validate compliance / certification?

• A plug • A label • A specific door reference

2. Is the certification number / evidence

relevant to the door leaf / door set? • Obvious!! But you’d be surprised

how rarely it’s checked

3. Is the door type / configuration correct?

• Single / pair

• Panel / flush etc.

1. Who glazed the door?

• If not done correctly, the certificate will be void

Door types

You may have specified an FD30 door, but . . .

Each door type below requires a different construction - AND a different test

It MAY NOT be suitable some configurations, certain components or for glazing

Panel Moulded

Panel Flush Glazed 1 ½ pair

with screen

Each door configuration is subjected to a different fire door test.

You cannot assume that any 2 single doors will work in a double leaf system

Door configurations

Ironmongery for Fire Doors must be compatible with the door

Essential Ironmongery

• Hinges

• Closers

• Locks and latches

Non-Essential Ironmongery

Handles

Knobs

Spy holes

Letter plates

EVERY door

Where do I find the information about the door leaf and components?

Checking the assembly

What to look for – after installation and in use

The Door Leaf Does the door have a certificate?

Is it 3rd-party certificated?

Does the door leaf sit in the door frame?

Is it free from distortion?

Is the door leaf free from damage?

No cracked / split panels

If the door leaf is veneered or lipped, is the glue still holding these products firmly in place?

Don’t consider upgrading an ordinary door with intumescent paints

It’s a very specialised job

You can’t apply the paint accurately enough with a paint brush

Don’t patch up the door

Door Frame

Is the door frame made from the right material?

Softwood (possibly MDF) for FD30 Hardwood for FD60 hour and above

Is the door frame firmly attached to the wall? Any SMALL gaps should filled with mineral wool or

fire rated material

Is the frame’s planted stop firmly attached to the frame?

Does the door close evenly into the frame

The gap is important

The frame to door leaf gap should be

3 to 4mm at the two sides and top

edge of the door

Threshold Gap

If a Fire Door – the permissible threshold gap is ~ 10mm. (Check the manufacturer’s instructions / evidence)

If a Fire and Smoke Door – the permissible threshold gap should be 3 to 4mm – the same as the perimeter gap.

Does the door freely swing, without binding?

Intumescent and smoke seals

Must be tested to BS 476: Pt 22

(OR BS EN 1634-1:2014 AND a separate test for smoke leakage under BS 476:

Pt 31.1)

Typically fitted into groove in door leaf OR PREFERABLY frame.

Fitted along 2 vertical sections and top edge

not fitted to threshold

Ideally, should be supplied, fitted by doorframe manufacturer.

If replaced due to repair MUST be equal to original doorset / assembly

Save lives, and property - prevent flow of cold / hot smoke

Many doorsets now need to provide fire, smoke and acoustic

containment

36

Fire & Smoke Seals

Is the Fire Door an FD30(S) or an FD60(S)? There is very limited substitution on FD30’s

and no substitution allowed on FD60’s

Are there any seals present in the door leaf or frame?

Are the seals free from damage? Are the seals continuous around the door leaf’s

perimeter? Are the intumescent seals, graphite or sodium

silicate? Don’t mix them

If combined fire and smoke seals, are the fins or brushes free from damage?

Is the door leaf to frame gap still 3 to 4 mm?

Intumescent Materials 3 main types

Exfoliating Graphite Most common type, 17 different types. Expansion between 170 – 300 °C High pressure seal, multi directional expansion

Hydrated Sodium Silicate Chemical formula, consistent in its performance Expands at 100 °C , consistently High pressure seal, multi directional expansion

Mono-Ammonium Phosphate Referred to as MAP Low pressure, high volume expansion

Commonly used for lock/latch and hinge protection kits

Glazing Detail

Are the glazing beads well attached to the door leaf and free from damage?

Is the glass free from damage and cracking?

Is the intumescent glazing seal continuous and attached to both the glass and bead?

If the glass is below 1500mm from the bottom of the door is the glass a fire- rated safety glass?

Who cut the vision panel & installed the glass? Check for a second label or a plug

Letter boxes

Air transfer grilles

Spy-hole viewers

Should be cut & fitted by

approved installers

Fire Rated ATG’s

On an FD30 or FD60: remove cover grille and check that a Fire Resistant air transfer grille has been fitted (giving hot smoke protection)

Ensure the ATG is free of blockages, replace if necessary.

If an FD30S or FD60S: ensure electro-mechanical device has been fitted (giving cold smoke protection) and works!

Periodic checks must be conducted with the fire/smoke alarm tests weekly (as required in RRO).

Does the vent automatically shut down when the power to the door is cut?

Ensure the electro-mechanical ATG is free of blockages

Check / maintain the ironmongery Replace if necessary

Essential Ironmongery

• Hinges

• Closers

• Locks and latches

Non-Essential Ironmongery

Handles

Knobs

Spy holes
