Q

How has the Regulatory Reform (fire safety) order been updated? The Fire Safety Act 2021

A
  • It clarifies who is the responsible for managing and reducing fire risks in parts of multi-occupied residential buildings.
  • Was created in response to Grenfeld fire tragedy.
  • Applies to buildings that are at least 18m in height or have at least 7 storeys and at lease two residential units.
  • It extends the provisions of the Regulatory Reform (fire safety) order 2005 to the building’s structure, external walls and anything attached to the external walls including cladding, balconies. Also now includes the all doors between the domestic premises and the common parts - the front doors of flats (fire doors) that lead onto escape routes.

Q

What is PAS 9980:2022?

A
  • Provides a methodology for the fire risk appraisal of external wall construction and cladding of existing multi-storey and multi occupied residential buildings.
  • It to be used by competent fire engineers and other competent building professionals.
  • It applies where there is a risk of fire spread from the form of building construction such as combustable materials and helps to inform the fire risk assessment.

Q

What are the different types of fire alarm? What document would you reference to ensure compliance?

A
  • BS 5839-1:2017 - Fire detection and fire alarm systems for buildings. Code of practice for design, installation, commissioning and maintenance of systems in non-domestic premises.
    Standards give description of main categories for fire alarm systems but systems are usually a mixture e.g category M (call points) and category L2 system.
  • Category M systems: Manual systems and therefore have no automatic fire detectors - call points located throughout.
  • Category L systems: Automatic fire detection and fire alarm systems intended for the protection of life which are further sub divided into:
    L1: systems installed throughout all areas of the building - gives the earliest possible warning of fire and longest time available for escape.
    L2: systems installed only in defined parts of the building. Objective of a Category L2 system is identical to that of a Category L3 system, with the additional objective of affording early warning of fire in specified areas of high fire hazard level and/or high fire risk
    L3: designed to give a warning of fire at an early enough stage to enable all occupants, other than possibly those in the room of fire origin, to escape safely, before the escape routes are impassable owing to the presence of fire, smoke or toxic gases.
    L4: systems installed within those parts of the escape routes comprising circulation areas and circulation spaces, such as corridors and stairways. The objective of a Category L4 system is to enhance the safety of occupants by providing warning of smoke within escape routes.
    L5: systems in which the protected area(s) and/or the location of detectors is designed to satisfy a specific fire safety objective (other than that of a Category L1, L2, L3 or L4 system).
  • Category P systems: Automatic fire detection and fire alarm systems intended for the protection of property. Further subdivided into:
    P1: system installed throughout all areas of the building - offers the earliest possible warning of fire to minimise the time between ignition and arrival of firefighters.
    P2: system only installed to defined parts of the building - offers early warning of fire in areas of high fire hazard level, or areas in which the risk to property or business continuity from fire is high.

Q

What is the building safety Act 2022?

A
  • Formerly the Building Safety Bill has now received Royal Assent and completed all parliamentary stages to become the Building safety Act 2022 in April 2022.
  • The main objective of the act is to give residents more power to hold builders and developers to account and toughen sanction against those who threaten their safety.
  • Applies to new and existing high rise residential buildings of 18m and above (or seven storeys or more) or mixed use buildings that have at least 2 residential units.
  • The bill includes the main issues / implementations:
    1. Implementation specific gateway points at design, construction and completion phases to ensure that safety is considered at each and every stage of a building’s construction and safety risks are considered at the earliest stage of the planning process. Will ensure that there is a ‘golden thread’ of information created, stored and updated throughout a buildings lifecycle which will establish clear obligations on owners and ensuring swift action taken by regulators.
    2. Includes measures for leaseholders for being responsible for the remediation costs of their building.
    3. Creation of the Building Safety Regulator (will sit as part of the HSE) - will oversee safety and performance of high rise and other buildings by working closely with local authorities, fire rescue services and experts, create expert committees including a statutory residents panel to ensure residents have a input into development of policy of the Building Safety Regulator.
  • Many measures are likely to take 18 months to introduce according to the government.

Q

What is the Golden Thread?

A

Dame Judith Hackitt, in her report, Building a safer future, recommended the introduction of a ‘golden thread’ to support dutyholders in designing, constructing and managing their buildings as holistic systems, taking into account building safety at all stages in the lifecycle.

‘a robust golden thread of key information’ should be ‘passed across to future building owners to underpin more effective safety management throughout the building life cycle’.

Use digital tools and systems’ to enable key information ‘to be stored and used effectively to ensure safer buildings’
support dutyholders and Accountable Persons throughout the life cycle of a building (during the gateways process, building registration process, the safety case approach and throughout occupation) ‘by recording the original design intent and ensuring subsequent changes to buildings are captured and preserved’
incorporate all the information needed to understand a building and how it should be managed so that the building and above all the people in and around a building are safe, both now and in the future
‘make information easily available to the right people at the right time’
put in place a new higher standard of information-keeping which will support the building safety regulator in being assured buildings are being managed safely

Q

What is the Hacket Report

A

A new regulatory framework for multi-occupancy higher-risk residential buildings (HRRBs) that are 10 storeys or more in height.
A new Joint Competent Authority (JCA) comprising Local Authority Building Standards, fire and rescue authorities and the Health and Safety Executive to oversee better management of safety risks in these buildings (through safety cases) across their entire life cycle.
A mandatory incident reporting mechanism.
New dutyholder roles and responsibilities aligned with the Construction (Design and Management) Regulations 2015.
A series of robust gateway points to strengthen regulatory oversight.
Stronger change control processes.
A single, more streamlined, regulatory route to oversee building standards. Oversight of HRRBs will only be provided through Local Authority Building Standards as part of the JCA, with Approved Inspectors available to expand local authority capacity/expertise or to provide accredited verification and consultancy services to dutyholders.
More rigorous enforcement powers.
A clear and identifiable dutyholder with responsibility for building safety.
Delivering building safety as a system rather than by considering a series of competing or isolated objectives.
A more effective testing regime with clearer labelling and product traceability.
Obligating the creation of a digital record for new HRRBs from initial design intent through to construction and including any changes that occur throughout occupation.

A

Assessment methodology of external wall systems.

Called a “FRAEW”.

50
Q

What is the process of a FRAEW

A
  • Intrusive inspection of external walls
  • Review of FRA
  • Gives recommendations to ensure building safety (eg. Get rid of “stay put” policy as lots of combustible material on external wall, install further alarms, get a waking watch)
  • Follow PAS 9980
51
Q

What three new roles does the Building Safety Act 2022 introduce?

A

Building safety Act 2022:

  1. The Building Safety Regulator (BSR) will oversee the safety and performance of all buildings, but special focus on high-rise buildings.
  2. The National Construction Products Regulator (NRCP) will oversee a more effective construction products regulatory regime, co-ordinate market surveillance and enforcement.
  3. The New Homes Ombudsman Scheme will allow relevant owners of new-build homes to escalate complaints to a New Homes Ombudsman. Enforcement framework and sanctions for breaching requirements.
52
Q

What is regulation 7 (2)

A

A1; Meeting the requirements of the Building Regulations as amended in 2018, including Regulation 7(2) would require the same as achieving an A1 rating on the EWS1, in that all combustible materials (primarily timber) would need to be removed from the makeup of the external wall and replaced. Regulation 7(2) is prescriptive and specifies that all materials in the external wall, with very limited exceptions, must be of limited combustibility. This is a fundamental change since the Building Regulations 2000 and 2010 contain functional requirements that the external wall must adequately resist the spread of smoke and fire.

53
Q

At what height is regulation 7 (2) relevant?

A

Regulation 7(2) applies to any building with a storey at least 18m above ground level and which contains one or more dwellings; an institution; or a room for residential purposes (excluding any room in a hostel, hotel or a boarding house).

54
Q

Q

What are the Fire Safety (England) regulations 2022

A

The Regulations came into force on 23 January 2023 Commencing January 2023, the Fire Safety (England) Regulations 2022 (the Regulations) make it a requirement for responsible persons of high-rise residential buildings to provide information on their building/s to their local fire and rescue service. A high-rise residential building is defined as a building containing two or more sets of domestic premises and is at least 18 metres tall or has at least seven storeys.

The Regulations 2022 have been introduced as an important step towards implementing the recommendations of the Grenfell Tower Inquiry Phase 1 report.

The information to be shared includes details of the construction of the external walls, floor and buildings plans, and information on known faults with key firefighting equipment. The Regulations state that this information must be shared via electronic means.

59
Q

What is an accountable person in relation to the Building Safety Act?

A

Accountable person:

Part 4 of the Building Safety Act identifies new dutyholders – who will be known as ‘accountable persons’ (APs) – for residential high-rise buildings (HRBs). This will be the organisation or person who owns or has responsibility for the building. It may also be an organisation or person who is responsible for maintaining the common parts of a building, for example corridors or lobbies.

The AP will usually be an organisation or business but could also be an individual.

The AP will have a duty to take all reasonable steps to:

  • prevent a building safety risk happening, with building safety risk defined as ‘spread of fire and/or structural failure’
  • reduce the seriousness of an incident if one happens

If a building has more than one AP, the AP responsible for the structure and exterior of the building will be the principal accountable person (PAP). When buildings have a single AP, that entity or person is the PAP.

As well as their duties as an AP, PAPs must:
– register existing buildings with the Building Safety Regulator (BSR), they can do this between April 2023 and October 2023
– register all new buildings before occupation
– All occupied buildings must be registered by October 2023, it is an offence if a building is occupied but not registered after this date.
PAPs must also:
– prepare a safety case report for the building.
– This should show that:
– APs have assessed all building safety risks and
– taken all reasonable steps to control them
– give the safety case report to BSR on request – BSR will examine it during the building assessment
– apply for a building assessment certificate when directed by BSR
– Detailed, accurate information about the building will be critical when registering a building and when preparing the safety case report.

60
Q

What is regulaton B4 (1)

A

The external wall does not meet Building Regulations Requirement B4(1) and it is therefore considered that the safety of building occupants is impaired, to at least some extent .
NOTE REGULATION B4. —(1) The external walls of the building shall adequately resist the spread of fire over the walls and from one building to another, having regard to the height, use and position of the building.

61
Q

What does a B1 fire rating mean on an EW1S?

A

A B1 rating means the engineer has decided the fire risk is low, and no remedial work is required.

62
Q

What is the difference between an A1 and A2 Fire Rated product?

A

A1 products are classified as non-combustible. A2 products are classified as limited combustibility. And B to F are classified as combustible in ascending order.

63
Q

What are the five possible results from an EW1S form?

A

There are five possible results from an EWS assessment.

Category A applies where buildings have external wall materials that are unlikely to be combustible. RICS says A1 and A2 findings “are not likely to lead to any further action.” An A3 finding means remedial work may be needed on attachments to the external wall, such as balconies.
Category B applies where combustible materials are clearly present. A B1 rating means the engineer has decided the fire risk is low, and no remedial work is required.
A B2 finding means there isn’t an adequate standard of fire safety and remedial work/interim measures are required.

64
Q

What were the remediation proposals you chose at Arden House?

A
  • Remove Eternit (A2) cladding and set aside;
  • Remove timber battens and discard;
  • Retain timber battens acting as barriers around window openings (subject to them being not less than 38mm thick, as required by Approved Document B);
  • Inspect and remediate horizontal and vertical cavity barriers;
  • Install new cladding supports in aluminium or other material of limited combustibility;
  • Refit Eternit cladding; and
  • Inspect plasterboard protection to steel frame to ensure 90-minutes fire protection.
65
Q

What is regulation 7(2)

A

Meeting the requirements of the Building Regulations as amended in 2018, including Regulation 7(2) would require the same as achieving an A1 rating on the EWS1, in that all combustible materials (primarily timber) would need to be removed from the makeup of the external wall and replaced. Regulation 7(2) is prescriptive and specifies that all materials in the external wall, with very limited exceptions, must be of limited combustibility. This is a fundamental change since the Building Regulations 2000 and 2010 contain functional requirements that the external wall must adequately resist the spread of smoke and fire.

66
Q

What is an accountable person and what is their role?

A

Who is the Accountable Person ?

The Accountable Person (AP) is a new role (distinguished from the Responsible Person under the Regulatory Reform (Fire Safety) Order 2005) for residential high-rise buildings (HRBs). This will be the organisation or person who owns or has responsibility for the building. It may also be an organisation or person who is responsible for maintaining the common parts of a building, for example corridors or lobbies.

The AP will usually be an organisation or business but could also be an individual.

The AP will have a duty to take all reasonable steps to:

prevent a building safety risk happening, with building safety risk defined as ‘spread of fire and/or structural failure’

reduce the seriousness of an incident if one happens.

67
Q

How does the Building Safety Act affect building control ?

A

All building control professionals, both local authority (now to be called Registered Building inspectors) and private Approved Inspectors (now to be called Registered Building Control Approvers), will come under the new BSR, including private firms. The BSR will therefore be the regulator forallnew buildings and any refurbishment, not just HRBs, although will only take a more direct interest as building control body in those buildings in scope (those HRBs 18m+ / 7-storeys or more with two or more residential units).

Competence validation will be an expected strong focus, and RICS is working with HSE to understand further how this will need to be demonstrated in future.

68
Q

What is the New Home Ombudsman Scheme and how does it impact surveyors? building safety act

A

The New Home Ombudsman Scheme (NHOS) is an independent redress scheme. Any new build buyers who have issues with their new home or developer who are not happy with the quality of their home, or the service provided by the Registered Developer will be able to submit a case to the NHOS if their developer doesn’t deal with the complaint effectively.

All developers will need to register with the NHOS and remain members of the scheme.

All RICS professionals who work on new build residential property should be aware of the NHOS and be aware that they may need to submit evidence as part of a dispute brought against the developer they’re working for.

69
Q

BSA What defines a ‘higher-risk building’ (HRB) or ‘relevant building’?

A

A higher-risk building (HRB) is defined as a building in England that:

is at least 18m in height or has at least 7 storeys; and
contains at least 2 residential units

70
Q

What is the Fire Safety (England) Regulations 2022 (came into force January 2023)

A

The Regulations came into force on 23 January 2023 Commencing January 2023, the Fire Safety (England) Regulations 2022 (the Regulations) make it a requirement for responsible persons of high-rise residential buildings to provide information on their building/s to their local fire and rescue service. A high-rise residential building is defined as a building containing two or more sets of domestic premises and is at least 18 metres tall or has at least seven storeys.

The Regulations 2022 have been introduced as an important step towards implementing the recommendations of the Grenfell Tower Inquiry Phase 1 report.

The information to be shared includes details of the construction of the external walls, floor and buildings plans, and information on known faults with key firefighting equipment. The Regulations state that this information must be shared via electronic means.

71
Q

What is the Building Safety Act 2022 (commenced April 2022)

A

Protects leaseholders from ridiculous costs to make safe cladding tall buildings (over 18m, and 2+ resi units), caps costs for non-cladding defects.
Makes those responsible for building safety defects held to account.
3 new roles:
- Building Safety Regulator (run by HSE)
- National Regulator of Construction Products
- New Homes Ombudsman
Made changes to Defective Premises Act 1972 (6 to 15 / 30 years)

72
Q

What is the Fire Safety Act 2021 (commenced May 2022)

A

Amends the RRO.
Increases obligations that “Responsible Persons” must manage and reduce risk of fire to external parts (cladding, balconies, windows), and entrance doors to flats.
RP can go to prison/be fined if not done.
Not height dependent!

73
Q

What is the Regulatory Reform (Fire Safety) Order 2005

A

Replaced 70 pieces of prior legislation.
ALL buildings EXCEPT individual homes (flats and houses).
Requires “designated person” to take measures to prevent fire and help escape. They must do:
- Fire Risk Assessment
- Have plans in event of emergency
- Review regularly
- Reduce risk as far as reasonably practical
Is not primary legislation as it is an ORDER not an ACT.

74
Q

What is the construction of Paul Byrne Court

A

Paul Byrne Court comprises three terraced houses of five storeys plus basement originally constructed around 1880/1890 which have been altered to form a single building. The top floor is below 18m in height and the external façade is of non-combustible masonry.. The building has 33 flats of various sizes with a standard (non-firefighting) lift in the central staircase. Means of escape from flats is through short, protected corridors or directly on to the escape stairs.

75
Q

What were the remedial soltuions at Paul Byrne Court?

A

The sprinkler installation should be extended to the eight flats that are currently unsprinklered.
New Fire Alarm system: LD1 standard within the flats should be interfaced with a warden call system. The warden call system should allow two way speech modules so that a resident can communicate with staff or a remote monitoring centre. Consideration should be given to incorporating an evacuation alert system
The new fire alarm panel should be addressable and capable of being programmed to achieve the desired cause and effect such as actuation of AOV’s or isolation of services such as gas. Stay put strategy.

The new fire alarm panel should be addressable and capable of being programmed to achieve the desired cause and effect such as actuation of AOV’s or isolation of services such as gas. Where a fire alarm panel is addressable and details flat numbers and room locations there is no requirement for a zone plan, but there is merit in providing suitable plan drawings for use by the fire service which they can take with them to assist in finding the relevant identified location. The BS5839-1 fire alarm system should also be remotely monitored
Many flat entrance doors have been replaced and are now known to be FD30S.

Electromagnetic hold open devices should be fitted to cross corridor doors which will assist the day to day use of the building for elderly or frail residents.

76
Q

What was the make up of the wall at Cooper’s Road?

A

The sections of timber cladding on the external street brick wall elevations are made up as follows * 20mm Timber Cladding Panel * 25mm Horizontal Timber batten * 25mm Vertical timber batten * Vapour Layer * 12mm Timber Plywood Board * 170mm Rockwool Insulation * Timber Frame + Internal Plasterboard The courtyard elevations were entirely clad with 20mm timber on battens, albeit that has been removed.

77
Q

What was the wall make up at Francis Bacon Court?

A

Francis Bacon Court:
The Steni Colour panels: The HPL cladding manufacturer, Steni, was not present during the investigations. used on this building were branded as B-s1,d0 which is the standard panel product (refer to the appendix in this report) and the supporting substructure is concrete slab, timber and cement block. It is used as a open joint rain-screen system which requires horizontal cavity barriers at each floor and around openings. The horizontal cavity barrier in this system should be intumescent to close the cavity only in case of fire. The damage to the installed mineral wool at second level shows that the detail has not been built to the standard required for a rain-screen system. The insulation is missing in most areas. It was observed in front of the floor slab to be Celotex which is not limited combustibility. It is suspected that the main insulation is behind the blockwork and the insulation added in front of the slab is to stop a cold bridging only. However without record information this cannot be confirmed.

Following the above investigation, we would conclude the following:
* The building is 6 storeys with no habitable floors over 18m above external ground level. The Steni rain-screen panel system has a fire rating of B-s1, d0 to EN 13501-1. The panels are mounted on timber battens infill at ground and first levels. The Steni Colour panel is considered combustible product.
* The insulation used behind the rain-screen is Celotex which is combustible.
/* The investigation showed that there were no cavity barriers in the areas opened up or if there was some mineral wool insulation it was installed not in accordance with manufacturer’s recommendation.
* All balconies have timber decking on galvanized beams exposed from underneath and inset side walls in HPL Steni (not investigated yet). In our opinion, it is concluded at this stage that the cladding system due to the above discrepancies (cavity barriers) does not meet the functional requirements of Part B4 of the Building Regulations. If the cavity barriers are reinstalled and supporting structure changed, the façade in our opinion may meet the ADB volume 2 guidance but the combination of combustible materials would still contribute to a fire spread. In order to upgrade or replace the cladding the following is recommended. Option 1 (subject to planning approval)
* To remove and replace the existing cladding together with the timber infill, with similar type of HPL but meeting the fire rating of A2-s1,d0 minimum and non-combustible sub-structure.
* Replace existing insulation with non-combustible insulation (mineral wool insulation) with cavity barriers to suit and comply with the current regulations.
* Install cavity barriers with mechanical fixings around openings.
* Timber deck balconies to be assessed with regard to the above improvements. Option 2 (subject to planning approval)
* To remove and replace the existing cladding together with the timber infill, with aluminium panel to match existing finish similar to Vitradual by Valcan meeting the fire rating of A2-s1,d0 minimum and non-combustible sub-structure.
* Replace existing insulation with non-combustible insulation (mineral wool insulation) with cavity barriers to suit and comply with the current regulations. * Install cavity barriers with mechanical fixings around openings. * Timber deck balconies to be assessed with regard to the above improvements.

78
Q

What was the wall make up at Arden House?

A

The information reviewed concurs on the make-up of the predominant external wall:
* Two layers of plasterboard (with vapour control layer installed);
* 140mm mineral fibre insulation (unknown product);
* Timber frame insert walling;
* 24mm OSB (orientated strand board) sheathing to external face of studs with breathable membrane
* 48mm air gap;
* 50mm x 50mm SW battens; and
* Marley Eternit Natura Range cladding panel.

The building is constructed on a steel frame with composite floors. The cavity between the OSB and the
Eternit cladding is fitted with some cavity barriers at compartment floors and walls; the workmanship of
the installation is poor as evidenced by the relatively limited invasive inspections reported by PRP

79
Q

What was the remedial solution at Arden House?

A

REMEDIATION REQUIRED
The following outline remediation works are therefore recommended to get the building to a position that
would have been acceptable under contemporaneous Building Regulations when designed, and to
provide an adequate level of safety to occupants:
* Remove Eternit cladding and set aside;
* Remove timber battens and discard;
* Retain timber battens acting as barriers around window openings (subject to them being not less
than 38mm thick, as required by Approved Document B);
* Inspect and remediate horizontal and vertical cavity barriers;
* Install new cladding supports in aluminium or other material of limited combustibility;
* Refit Eternit cladding; and
* Inspect plasterboard protection to steel frame to ensure 90-minutes fire protection.
This solution retains the timber frame walls and the OSB, but finishes up with a system that is comparable
to or better than systems that are known to have passed BS8414 tests, for example systems using K15
insulation and limited combustibility cladding

An alternative scheme, if considered necessary, could include the removal of the OSB and replacement with cement particle sheathing board, which would also require re-fitting of cavity barriers

81
Q

Rainscreen cladding:

A

Rainscreen cladding In rainscreen construction, decorative cladding material is applied over old or new walls to provide a lightweight skin to improve the aesthetics of buildings, and provide thermal insulation behind the cladding, and weather resistance. Depending on the design and construction, a ventilated cavity is formed between the cladding and the backing insulation/wall, which facilitates rainwater drainage. This cavity can create a ‘chimney effect’ where fire and smoke can travel unimpeded within the zone, but it can be controlled with installation of cavity barriers and fire stops. The cavity in rainscreen cladding is a weakness in the system (and there-fore proper design, installation and workmanship are essential in these systems) as opposed to standard aluminium framed curtain walls. Rainscreen systems are available in many different forms and some are discussed below.

82
Q

Ventilated rainscreen cladding:

A

Ventilated rainscreen cladding Ventilated rainscreen cladding systems are a form of multi-layered façade construction. These popular cladding systems, are significantly different to curtain walls, comprise open jointed decorative rainscreen panels, typically fixed to a lightweight support structure comprising timber sections or aluminium extrusions secured back to an airtight backing wall. The rainscreen panels can be made of a wide variety of materials, such as metal panels (including alumin-ium, zinc and copper), HPL, terracotta and stone for example. Insulation boards and breather membranes are typically installed in the ventilated cavity formed between the rain-screen panels and the backing wall. The backing wall is normally installed as a storey height infill panel, typically between floor slabs. Such panels can be assembled on site or prefabricated in factory conditions. Backing walls can also be installed as a continuous walling solution fitted in front of the floor slabs. They can also be an insulated metal sandwich panel. Horizontal and vertical cavity barriers between the external cladding and the backing wall must be installed within the cavity.

Why would your proposal at Arden House be acceptable?

A

The outcome would be system equal or better than systems known to have passed BS8414 tests. This would be acceptable under contemporaneous Building Regulations and would ensure the properties were mortgageable for leaseholders

90
Q

The Defective Premises Act & unfit for habitation:

A

The Defective Premises Act enables claims to be made for defective work relating to the construction of dwellings where the work renders the dwelling unfit for habitation. The limitation period (deadline) for claims brought under the Defective Premises Act is extended from 6 years to 15 years for new claims.

91
Q

Defective construction products and uninhabitable:

A

Where the use of defective construction products leads to the building being uninhabitable the limitation period will be 15 years. If the claim relates to a cladding product however, there will be a 30-year retrospective limitation period.

92
Q

How would you know a material is combustible?

A

testing / manufacturers guidance – BBA certification / Plans. Taken to a lab. UKAS accredited company which can analyse flammability of material. Approved document B – has a table in it which lists what materials are combustible.

93
Q

Cavity Closers:

A

Cavity closers It is important to note that cavity closers are different to cavity barriers. Cavity closers are typically specified to control watertightness, dampness, heat loss and condensation within the cavity of masonry walls and may or may not provide protection against fire spread. Typical, cavity closers are made of combustible PVC extrusions where the core is filled with rigid insulation

94
Q

What are Fire-stops

A

Fire-stops should not be confused with cavity barriers. Fire-stops are fitted between the backing wall and any fire-separating element (floor slabs or partitions) to maintain the continuity of fire resistance between these elements (e.g., 60 min, 90 min or 120 min). Fire resistance of fire stops must be equal to or exceed that of the elements they separate. Fire-stops are typically made of non-combustible high-density stone wool (Class A1) and are normally covered with a foil or white ablative coating

97
Q

What is included in Approved Document B:

A

ADB (in two volumes) contains statutory guidance on fire safety, including means of escape, fire spread, structural fire protection and fire service access. Volume 1 covers dwellings (including flats) and Volume 2 covers buildings other than dwellings.

98
Q

Cavity barriers

A

Typically elements of fire-resistant materials which are fitted
within building cavities typically horizontally or vertically to assist
in preventing fire spread within cavities. Cavity barriers typically
are only recommended to provide 30 minutes integrity and 15
minutes insulation

99
Q

Curtain wall

A

An external covering of a building in which the outer walls are non-structural, used only to keep the weather out and the occupants in a safe and controlled environment. It is usually a
prefabricated system made of relatively lightweight materials, fixed directly to the structure.

100
Q

Euroclass system

A

Determines the fire performance of any product by measuring a comprehensive set of characteristics, including ignitability, flame spread, heat release, smoke production and propensity for producing flaming droplets/particles. BS EN 13501-1 categorises products into one of seven classes of reaction to fire, ranging from A1 (non-combustible) down to F (the worst performing class in terms of combustibility), using defined tests or combination of tests.

101
Q

Fire-stop

A

A form of passive fire protection that is used to seal around openings and between joints in a fire-rated wall or floor assembly. Fire-stops are designed to maintain the fire resistance of a wall or floor assembly to impede the propagation of fire and smoke. Fire barriers are typically recommended to have a fire resistance rating of more than 60 minutes of integrity and insulation.

Q

What are the Classification of Fires?

A

Fires are classified in six groups A, B, C, D, F and electrical:

Class A fires – are fires involving organic solids like paper, wood, etc
Class B fires – are fires involving flammable liquids
Class C fires – are fires involving flammable gasses
Class D fires – are fires involving burning metals (eg aluminium swarf)
Class F fires – are fires involving fats such as used in deep fat fryers
Electrical fires (the letter E is not used. Instead the symbol of an electric spark is displayed) – are fires caused by electrical equipment
