PENETRATIONSNine ‘Golden Rules’

1GOLDEN RULE

Ensure an early engagement with firestopping manufacturers and specialist installers.

2GOLDEN RULE

Review the fire strategy documents and fire strategy plans in conjunction with the M&E specifications.

3GOLDEN RULE

Identify all of the service types passing through the compartment floor or wall including any insulation products. Establish the space required to install and firestop the services.

4GOLDEN RULE

Follow the ‘Design process for penetration seals’.

6GOLDEN RULE

Ideally select one firestopping manufacturer throughout the project. Products from different manufacturers should not be missed in the same opening unless there is clear test evidence to substantiate their use.

7GOLDEN RULE

Request copies of the third party certification from the manufacturers. These should be reviewed by a suitably qualified person to ensure the certification and field of application is relevant for the situation.

8GOLDEN RULE

Ensure the installers of ALL service penetration seals are third party certified by an organisation such as FIRAS, LPCB, IFC, BM TRADA etc.

9GOLDEN RULE

Implement a structured inspection plan to include photographic evidence as the work proceeds.

5GOLDEN RULE

Only select firestopping products which are third party certified by a UKAS accredited organisation. Firestopping products should be certified or CE marked and tested using the relevant standards.

Presentation Notes

GR1 - Ensure an early engagement with firestopping manufacturers and specialist installers.


PENETRATIONSWhat is compartmentation ?

Presenter

Presentation Notes

Fire compartmentation in buildings is generally provided by separating elements such as walls, floors and ceilings. It is designed to protect people in and around the building, including fire and rescue personnel, from the effects of the spread of fire by containing it in the compartment of origin for a specified period of time. Compartmentation subdivides buildings into areas of manageable risk to provide adequate means of escape and to provide fire separation for adjoining buildings. Firestopping is required to maintain the specified level of fire compartmentation where services penetrate the compartment walls and floors.


PENETRATIONSEarly cooperation communicationand coordination is key• Design process

• Start by defining the responsibilities for the project

Presenter

Presentation Notes

- The Construction (Design and Management) Regulations (CDM) will always take precedence. - Golden rules used for services penetrations through fire fire-separating elements to ensure compliant design, selection and installation of penetration seals. - The principal designer under CDM is responsible for ensuring the product specified either initially or through subsequent design changes meets the performance requirements required to comply with the Building Regulations. This may include examining engineering judgements, technical evaluations, certification and test reports.


PENETRATIONSEarly cooperation communicationand coordination is key• Collaboration

• For any penetration seal to besuccessful, there must becollaboration between all partieswith adequate time allowed.

Joe analogy; Car taken in for a service and when returned there is an oil leak. After checking there was no engine fault, it was found that mechanic had forgotten to tighten the sump nut. He may have had the skill, knowledge and experience but the attitude was wrong.


PENETRATIONSDeveloping strategies for fire and M&E

Presenter

Presentation Notes

GR 2 - Review the fire strategy documents and fire strategy plans in conjunction with the M&E specifications. GR3 - Identify all of the service types passing through the compartment floor or wall including any insulation products. Establish the space required to install and firestop the services.



• Building fire strategy

Presenter

Presentation Notes

It is essential that designers, contractors and all those involved in a project read and understand the fire strategy document and/or fire strategy drawings. This doocumnet must be made available during the construction phase Approved Document B provides guidance on achieving the functional requirements of the Building Regulations BS 7974 Fire Engineering can offer flexibility and innovation



• Competency to prepare a fire strategy

‘It is vital that those entrusted to prepare a fire strategy have the necessary levels of competence to undertake the task professionally and thoroughly. The level of competency required will be commensurate with the expected complexity of the building to be assessed…’

Presenter

Presentation Notes

a) A good understanding of fire-related aspects of premises and their function b) An appropriate knowledge of fire legislation and the requirements of other enforcing bodies c) Appropriate qualifications, training and/or experience in fire safety and fire protection issues d) Knowledge of relevant national codes and past experience of their application.



• Mechanical and electrical (M&E) strategy

Presenter

Presentation Notes

Consulting engineers should consider penetration seals and not rely on the Contractor’s Designed Portion (CDP) element. This is to avoid the design of the penetration seal being considered too late. In this slide, the services were designed, 100 copper pipes with insulation, but no consideration of how this could be firestopped!



• The services should be designed in conjunction with the penetration seals, so they allow for a compliant installation


PENETRATIONS

And that they can be installed safely

• CE marking

• Quality mark aimed at allowing movement of goods across EU

• Manufacture must declare products performance in line with a European Technical Assessment… ETA rules laid out in European Assessment Document

• Assessment body produces a Certificate of Constancy of performance



• Technical evaluations

• It is not possible to test all possible Penetration Seal configurations and site conditions that occur

• 1 off Technical Evaluations can still be used to evaluate likely performance where testing is not possible or uneconomic

• Section 4.5 covers in more detail underpinned by ASFP Advisory Note 17



• Support of services• Services often installed before Firestopping

considered• Service design does not consider

requirements of firestop support

• First support is located further away from wall than test data

• Although works in cold state, no idea how this will affect fire state performance

• Support should be provided as test data detail

• Benchmarking and samples

Presenter

Presentation Notes

Once the type of service penetrations is established, the design layout determined, the penetration seals and fixings specified and a penetration manufacturer selected, a sample wall and floor should be constructed for the project. This will allow each type of firestop to be replicated (where practicable to do so) and this can be used as a control sample for all to see and understand.



• Installation

Everybody involved with the design and installation of penetration seals shares the responsibility for their performance

in the case of a fire.



• Why do we need 3rd Party Certified Installers…..

• Three fundamental requirements to be allowed to install firestopping

• So we recommend you insist on 3rd Party Certification of your installers



• Third party installation certification

Presenter

Presentation Notes

Third-party certification from independent UKAS-accredited bodies for installers is a process whereby the contracting company is seen to employ appropriately trained and competent staff to install the required passive fire protection system. Their work is independently audited by site inspections from the independent tthird-party organisation and a full record system is required as part of the scheme. A record of installation is issued on completion to the main contractor foreach contract. The u. The use of certified installers will reduce the incidence of firestopping materials being installed by unskilled contractors and the use of unsuitable materials and reduce essential work and rework considerably.se of independent third party certification and accreditation is recognised in Approved Document B

• Competency scheme

Presenter

Presentation Notes

The ASFP foundation course in passive fire protection provides essential knowledge as part of demonstrating competency and understanding in this key fire protection specialism. The content of the training embeds current best practice and draws on the technical expertise provided by the ASFP. The foundation courses have been developed in partnership by ASFP and the Institution of Fire Engineers (IFE), a nationally and internationally established awarding organisation, recognised by the qualification regulator Ofqual. The foundation courses aim to equip candidates with the knowledge required to demonstrate competency, while also offering a route for progression and academic recognition in this key fire protection specialism. The level 2 course is designed for installation team leaders and senior installers, whilst the level 3 course is suggested for anyone who works in the design or inspection / assessment of passive fire protection.



• Fire prevention on construction sites

Presenter

Presentation Notes

Complaint firestopping is not just for the completed building, Its also for the construction phase. This publication is suitable for all parties responsible for fire safety prior to and during the procurement, construction and design process.



• Labelling of fire separating elements

Presenter

Presentation Notes

Service penetration seals should be clearly labelled by the specialist contractor on completion with the following information: • Unique reference number of the penetration and the seal • Installation date • Name of the operative who installed the seal • Name of the supervisor who inspected the seal • Name and contact details of the manufacturer • Name and contact details of the specialist contractor • Date of next inspection.


PENETRATIONSWarning notice

Presenter

Presentation Notes

ASFP and FIS have a Fire Performance Partition Labelling Scheme as part of a commitment to improve safety. This aims to identify fire-separating elements to installers, M&E contractors, building owners and facilities managers and to highlight the risks of cutting holes in them for services.

Starting point Industry standard fire stopping details

only

Fire stopping products selected early to enable standard details to be incorporated into the design

Engineering judgements considered by absolute exception

Defined and agreed responsibilities for everyone in project team


Presenter

Presentation Notes

Presenter Notes:

BDP Approved Details Produced NG Bailey Spacing Rules Detailed

• Project specific fire stopping reports were produced by BDP with technical input from Balfour Beatty and NG Bailey.

Approach to Design


Presenter

Presentation Notes

Presenter Notes: These reports include approved details, builders work rules, schedule of services and associated treatment, evidence of decision making, together with any evaluation judgements. As already mentioned, from the outset, a key objective was to only install industry standard fire stopping details. Spacing rules were developed based on the agreed fire stopping manufacturers tested & approved details. These rules considered items such as: Diameter of pipework services including insulation Proximity to other services within the penetration Edge distances between the penetration service and the supporting construction


Approach to Design

Presenter

Presentation Notes

Presenter Notes: For example, a 42mm copper LTHW pipe will have the following requirements: For 30/60/90 minute fire compartment walls - 25mm of fire rated insulation For 120 minute fire compartment walls - 40mm of fire rated insulation

NG Bailey Builders work Drawing produced

BIM Model used to define openings

Partition subcontractor creates the openings

Services are installed and Fire Stopping contractor seals the

opening


Presenter

Presentation Notes

Presenter Notes: This slide demonstrates how BIM was used to model all of the builders work penetrations in the partition walls. In the centre of the drawing, once all the co-ordination was carried out, NG Bailey produced a builders work drawing that defined a unique reference for each penetration with setting out dimensions and invert levels. The partition sub-contractor used this information to create the builders work penetrations

• Typical sequence of installation as follows:

o Partition Contractor forms the opening (as per NG Bailey builders work drawing)

o NG Bailey install services through the opening and sign over to Fire stopping Contractor

o Fire stopping Contractor installs fire rated insulation product on pipework (500mm either side of compartment line)

o Fire stopping Contractor close the opening with Ablative Batt

o NG Bailey thermally insulate the pipework up to the fire rated insulation

o NG Bailey foil wrap up to the Ablative Batt (over the fire rated insulation ) to maintain the vapour barrier


Approach to Design

Common technical issues/lessons learnt


InsulationBracket Spacing Pipework Movement

Penetration Co-ordination

Presenter

Presentation Notes

Presenter Notes: Bracket spacing - either side of fire walls should be in line with the tested and approved detail. This is typically 500mm. Pipework movement - for expansion needs to be considered in conjunction with fire stopping. Penetration co-ordination - Services were designed above door jamb zones, without considering the support steelwork/studs. As a result, significant re-coordination was initially carried out, with “goalpost” support steelwork installed above the doors in areas that couldn’t be re-coordinated. Insulation – Where fire rated insulation is used, ensure pipe fittings or components are located outside the 500mm zone otherwise fire stopping solution will be compromised. Note: The intention of the guide isn’t to provide solutions to individual technical issues but to provide structured best practice guidance to ensure passive fire stopping is approached in the best possible way.

Key Lessons Learnt

Fire stopping of service penetrations needs to be considered

early

A collaborative approach and early selection of fire stopping products enabled standard details to be incorporated at design stage.

It is essential that responsibilities are agreed for every

stage.

Defining project fire stopping rules and critical dimensions proved valuable.

A single authority responsible for passive fire stopping was

key.


Presenter

Presentation Notes

Presenter Notes: Fire stopping of service penetrations needs to be considered early – i.e. when space planning MEP services distribution. Consultants designs should be checked to ensure they are in compliance with standard tested and approved fire stopping details. A collaborative approach and early selection of fire stopping products enabled standard details to be incorporated at design stage and avoided unnecessary co-ordination - Get it Right First Time. It is essential that responsibilities are agreed for every stage - (design, BIM, builders work, services installation and fire stopping). Defining project fire stopping rules and critical dimensions including construction tolerances proved valuable. A single authority responsible for passive fire stopping was key.
