Legislation

There are a number of regulations relating to providing safeworking environments. However, as far as working at height isconcerned, the following are the most pertinent:

• Before any form of work at height is undertaken a riskassessment must be completed in line with the Managementof Health & Safety at Work Regulations 1999 for everyprocedure that is carried out during a given operation.

• Workplace (Health, Safety and Welfare) Regulations areprobably the most relevant in terms of ensuring the health andsafety of workers. Regulation 13 in particular relates to fallsfrom height and states that as far as is reasonably practicable,suitable and effective, measures shall be taken to prevent anyperson falling a distance likely to cause personal injury.

• Construction Design & Management Regulations 1994 areabout management of health and safety and apply toconstruction projects and all those associated with them,including clients, designers, contractors and operatives. Theregulations apply to non-domestic construction where:

- work takes 30 working days or more

- work takes more than 500 man hours

- five or more people will be working on the project at any one time

- demolition work is involved

- any design work regardless

Under CDM Requirements, designers must:

• Consider during the development of designs the hazardsand risks which may arise from those constructing andmaintaining the structure.

• Design to avoid risks to health and safety as far as isreasonably practicable.

• The Construction (Health, Safety & Welfare) Regulations1996 require that:

- There shall, so far as is reasonably practicable, besuitable and sufficient safe access to and egress fromevery place of work and to any other place providedfor the use of any person while at work.

- Suitable and sufficient steps shall be taken to prevent,so far as reasonably practicable, any person falling.

This should include the provision of safe access and egress for:-

a) Any guardrail, toe-board, barrier or other similar means of protection; or

b) Any work platform

If this is not practicable then suitable personal suspensionequipment or means of arresting the fall must be provided (safetynets). The regulation also includes requirements on ladders thatthey should not be used as a means of access or egress or asplaces of work unless it is reasonable to do so having regard tothe nature or duration of work being carried out.

Safety should be an inherent part of any workplace, especially when one of the greatest risks relates to working at height.

Data from the HSE shows that falls from height accounted for 47% of fatalities and 30% of major injuries in the 2001/02 period

in construction. It is still the most common cause of accidents in the industry.

When it comes to working at height a safe environment must always be provided. Since 1991 more than 500 accidents and 80 fatalitieshave occurred as a result of falls from height in the construction industry.

Employers, designers, constructors, employees and all those in control of work are responsible for providing the necessary safety equipmentand protection.

Site Safety - Remember ignorance of the law excuses nobody!



32

The Role of the ClientThose who own, occupy or have responsibility for a building havean important role to play when arranging for construction work tobe done. This includes considering the design and specification ofa new building, appointing a contractor for refurbishment orinstructing an employee to carry out an emergency repair.

Unrealistic building or refurbishment programmes can lead toundue pressure on those carrying out the work. This can make itharder for contractors to plan for safe working, to prepare qualitysafety method statements and to review and amend systems ofwork. Clients have an important role here. They should avoidplacing unreasonable programming demands on the project.

For projects to which the CDM Regulations 1994, clients must:

• Appoint a competent planning supervisor and principalcontractor and check that any other designers orcontractors they appoint are competent. Clients shouldsatisfy themselves, as far as they reasonably can, thatthose they appoint to carry out work on the project arecompetent to do so and have the necessary resources.This could, for example, include enquiries on:

- membership of the relevant trade bodies orprofessional organisations.

- previous experience of similar work.

- arrangements for managing health and safetystandards.

- references from previous clients.

- time needed to carry out the work safely.

• Provide relevant information needed to allow the work to bedone safely. This could include information on:

- what an existing roofs and walls is made of,especially if it contains fragile materials.

- the age of an existing construction.

- previous modifications made.

- existing arrangements for access.

- restrictions on availability of space for cranage orhandling equipment.

- relevant permit to work arrangements operated bythe client.

- fire prevention precautions.

- areas where contractor access will be prohibited.

• Ensure that an adequate construction phase health andsafety plan has been prepared by the principal contractorbefore work actually starts.

• All designs, specifications and materials should comply withthe CDM Regulations.

The CDM Regulations do not apply to smaller scale, short livedconstruction, but even if CDM does not apply, its underlyingprinciples of effective health and safety management should still befollowed. They will help clients to comply with their wide ranginggeneral duties under the Health and Safety at Work, etc., Act1974 to exercise reasonably practicable care for the health andsafety of themselves, their employees and others such ascontractors and members of the public.

Duties on clients do not apply to private householders when theyhave construction work carried out on domestic property.

Clients can benefit considerably from a structured approach tohealth and safety. Better planning and better systems of co-ordination between designers, contractors and specialistsubcontractors can lead to:

• reduced delays

• a building that is easier and cheaper to maintain

Work at height is more expensive than similar work done atground level. This additional cost can increase dramatically if it isnot properly organised and controlled.

The Role of the DesignerUsing their professional skills and judgement, designers caneliminate hazards and make risks easier to manage. This helpscontractors to provide a safer place to undertake the work.Designers need to consider the initial construction work as well asfuture maintenance and cleaning requirements.

Under the CDM Regulations designers have a duty to ensurethat their designs give adequate regard to health and safety.Foreseeable risks should be avoided. If it is not reasonablypracticable to avoid them, they should be combated atsource. Priority should be given to design solutions providinggeneral rather than individual protection.

For example:

• eliminate fragile materials.

• minimise the need for work at height during construction.

• minimise inspection and maintenance requirements for thecompleted roof and wall envelope.

• identify and design in safe access and working formaintenance and cleaning.

• consider carefully the siting of plant which will requiremaintenance. Are there alternatives to placing it on theroof? If not, is it in the optimum position on the roof wheresafe access can most easily be provided?

• consider carefully rooflight location.

• provide clear and unambiguous specifications for safetycritical elements of the design.

• provide information relevant to construction andmaintenance for inclusion in tender documentation and inthe health and safety file.

The design of the roof and wall should be reviewed as a totaldesign package. It should take account of the interaction betweenall components (in both final and partially erected state) and theireffect on the systems of work necessary to erect the structure.

Designing RoofsAccess to roofs is often simple and it can be easy to walk aroundon them. Accidents happen not just to roof workers but also toengineers, surveyors, children, caretakers, etc. The first priority isto design out the risk at source, for example by specifyingadequate in-built edge protection. Designers should consider thealternatives available in terms of their effectiveness in preventingfalls, as well as cost, aesthetics and buildability.

Edge ProtectionEdge protection options in order of effectiveness are:

• designed parapet.

• guardrail at the roof edge.

• permanent protected walkway for access to plant on the roof.

• preformed sockets to support temporary edge protectionguardrails.

• running line systems designed, installed and tested to therelevant standards.

Designers should be aware of the requirements of the Workplace(Health, Safety and Welfare) Regulations 1992.



34

The health and safety file should include relevant information fromthe supplier, such as:

• test results on the initial material strength.

• the effects of ultra-violet radiation on material properties.

• fixing specifications, including type, number and position.

Rooflights

For rooflights designers should consider carefully the potentialto eliminate or reduce this hazard.

The decision on whether to include rooflights should take accountof the risks associated with temporary gaps during construction,and the risks when access to the roof is needed later, such as,during maintenance or cleaning.

Where rooflights are required designers should consider:

• specifying rooflights that are non-fragile

• fitting rooflights designed to project above the plane of theroof and which cannot be walked on (these reduce the riskbut they should still be capable of withstanding a personfalling onto them).

• specifying rooflights with a design life that matches that ofthe roof, taking account of the likely deterioration due toultra-violet exposure, environmental pollution and internaland external building environment.

Kingspan rooflight systems are non-fragile and fully HSEtested to ACR {M} 001: 2000

Fragile MaterialsThe most important issue for designers is how to design out fragilematerials or eliminate unprotected fragile materials at height.Designers should consider carefully the potential how toeliminate or reduce this hazard.

Whatever the roof and rooflight systems used, the assemblyshould be tested to determine fragility and the relevant informationpassed on to those who need it.

Roofing Systems

The safest option is to specify a roof system which is non-fragile during construction and over its design life.

Kingspan insulated roof systems are non-fragile, simple andfast to install and are load bearing independent of fixings.

Handling of very long roof panels can be dangerous for roofworkers and others, even in moderate winds. Designers need todecide the maximum wind speed in which these panels can belaid. The National Federation of Roofing Contractors’ in the UKrecommend that general sheeting works should be stopped whenthe wind speed reaches 23mph or gusts to 35mph or over.However, for multi-skinned sheeting (built-up systems) theyrecommend that sheeting works stop when the wind speedreaches 17mph or gusts to 26mph or over when laying thelightweight elements (liner sheet, vapour control layer, insulation,breather membrane).

Roof MaintenanceDesigners can help reduce the amount of work done at heightthroughout the life of the structure. For example, they could:

• increase the maintenance life of roof elements

• locate plant and equipment at low level wherever possible

• design gutter detailing to reduce blockages

Co-operation with OthersGood liaison between designers can achieve better standards atall stages of the work. A practical example is the effect of gutterdesign on systems when the roof is laid.

Roof workers and others commonly use gutters for access ateaves level along the roof. The structural strength of the gutter, itswidth and depth and the quality of the fixings greatly affect itssafety as a means of access. Where gutters are not strong enoughor are fitted after the roof cladding is fixed, means of access willbe needed which takes this into account. Problems can often beavoided if designers consult with each other.

There are a number of issues where the design of the frame of thestructure has a direct effect on the systems of work of the roofworkers. For example:

• if running lines are to be used during erection, thenanchorage points need to be designed into the frame atappropriate points.

• the design and sizing of purlins and the alignment of thejoints between purlins can determine whether or not atrolley system can be used successfully.

• the position of sag rods can affect systems of work.

• the design of eaves beams is relevant to the installation ofnets and to the stability of scaffold tube edge protection.

Resolving these issues requires close co-ordination between frameand cladding designers.

Safety PlanningSafety planning for roof and wall construction includes all scales ofnew build and refurbishment projects. Planning by client, planningsupervisor (where CDM applies) and contractors helps to ensurework is carried out safely, efficiently and without undue delay.

Short duration work can be very high risk, such as minor repairs toa factory roof containing fragile rooflights. Accidents happen whensuch work is poorly planned, the proper equipment is not providedand roof workers are inadequately trained.

Roof and wall construction should only be undertaken by thosewith the knowledge, experience, training and resources tocomplete the work safely. Thorough planning, instruction andeffective ‘on the spot’ supervision are essential for accidentprevention.

A safety method statement should normally be prepared beforeany work starts. It needs to be appropriate to the scale andcomplexity of the work. In all cases, it should ensure that risks arerecognised and assessed and the appropriate control measuresspecified.

Safety method statements should be clear and illustrated bysimple sketches. There should be no ambiguities orgeneralisations which could lead to confusion. They should bewritten for the benefit of those carrying out the work and theirimmediate supervisors. Equipment needed for safe working shouldbe clearly identified. It should also be clear what to do if the workmethod needs to be changed. This should avoid ‘ad hoc’methods of work on site and the use of improvised equipment.

The following sections describe what planning supervisors,principal contractors and contractors need to do when CDMRegulations apply. CDM Regulations will not apply to much short-term roof work. However, CDM Regulations are based onfundamental principles of effective health and safety management.Short-term roof work is high risk. Those managing or controlling itneed to exercise effective management and procedures similar toCDM can still be used for this purpose.

Planning SupervisorsPlanning supervisors will have an important role to play whereCDM Regulations apply. For example:

• if requested by the client, they will advise on competence ofdesigners and contractors.

• they will ensure that a pre-tender health and safety plan forthe project is prepared.

• they may advise the client on the adequacy of the healthand safety plan for the construction phase.

The pre-tender health and safety plan should answer these basicquestions:

• What are the major health and safety risks on this project?

• Are significant resources needed to control these risks?

• What specific competencies are required to carry out thework safely?

The pre-tender health and safety plan should then:

• set out any basic assumptions about how the work will bedone to control the significant risks

- use of safety nets for industrial roofs, use of mobileaccess equipment to install gutters and erect edgeprotection.

• identify programming implications of safe systems of work

- provision of suitable ground conditions for mobileaccess equipment, allowing time for blockwork to curebefore trusses are installed.

• Identify any aspects of the client‘s activities having healthand safety implications

- times when significant vehicle movement can beexpected.

• clarify any other specific requirements by the client

- for repairs to a school roof, the client might specify thatwork is done during school holidays.

The pre-tender health and safety plan should contain relevantinformation provided by the client or by designers. For example:

• the load bearing capacity of a flat roof.

• ground conditions and access for crane(s).

• information from the designer on sequence of erection,temporary stability and bracing of trussed roofs.

• presence of asbestos insulation board in soffits.

• presence of sprayed asbestos on trusses or purlins.

• position and type of overhead power lines including thoseassociated with railways.

• design information on fixing details necessary to ensure non-fragility.



36

Principal ContractorsPrincipal contractors are the key players in setting practical on-sitesafety standards and ensuring that they are actually followed.They should:

• ensure that the overall work programme gives enough timefor work to be done safely by sub-contractor, takingaccount of likely weather conditions.

• allow time to consider method statements and deal with theimplications of design changes.

• devise a work programme which reflects the need tocontrol access to areas below roof work where there isdanger of falling materials.

• specify clearly at tender stage the resources allocated tocontrol and manage risks such as falls from height.

• ensure that relevant information is passed to the contractor.

Principal contractors need to ensure that adequate constructionphase health and safety plan is in place before construction starts.The plan needs to set out explicitly how the work is to be done inpractice and the precautionary measures that need to be taken.

Safety method statements can usefully form the basis of theconstruction phase health and safety plan. They are usually drawn upby individual contractors rather than the principal contractor. Principalcontractors need to scrutinise contractor method statements.

They need to satisfy themselves that these are appropriate andadequate for the work in hand. It is not acceptable for principalcontractors to merely specify that method statements are drawnup. They need to establish an effective system for reviewing them.

Principal contractors need to monitor compliance with theconstruction phase health and safety plan and take positive actionto remedy matters if risk is not being effectively controlled.

ContractorsContractors need to:

• prepare safety method statements that are relevant to thework being done.

• ensure that they and their employees are competent tocarry out the work in hand safely.

• co-operate with the principal contractor in implementing theconstruction phase health and safety plan.

More information can beobtained from the HSE’s‘Health and Safety inRoof Work‘ publication.

AppendicesAppendix 1 Issues for method statements in industrial roof workAppendix 2 Use of safety netsAppendix 3 Use of safety harnesses and running line systemsAppendix 4 Fragility: tests and specifications

Applying the CDM Regulations is a collaborative effort.The Regulations only become effective when people worktogether to tackle health and safety risks.

BuildabilityKingspan insulated roof and wall systems are factory pre-engineeredenabling safer, simple, cost-effective, rapid and superior quality siteconstruction. This facilitates reliable and fast site programmecertainty, lower prelim and attendance costs, ‘on time’ projecthandover and earlier client/tenant trading income payback comparedwith multi-part site-assembled envelope systems.

Build SpeedKingspan single component, single fix insulated roof and wallsystems can typically reduce on-site construction time by up to 50%compared with conventional built-up, multi-part roof or wall on-siteassemblies. This allows the site installation of roof and wall systemsto be removed from the building programmes’ critical path.

Full regulatory compliance – built-in“ ”


Step 1 - Envelope DesignKingspan provide roof and wall solutions and construction detailsfor building designers which achieve Parts L2 or J compliance for U-values, thermal bridging, condensation risk, air leakage andinsulation continuity.

These solutions also enable the integration and downsizing ofHVAC services plant, reducing lifetime energy usage, operatingcosts and Carbon Dioxide (CO2 ) emissions by up to 40%.

Reasons for Changes to ApprovedDocuments Part L2 (England & Wales) and Part J (Scotland)World wide concern regarding climate change and the impactwhich greenhouse gas emissions have on the environment haveencouraged governments to act. The latest revisions to Parts L2and J is to reduce both the emission of greenhouse damaginggases by 12.5% and the levels of CO2 emissions by 20% below1990 levels by 2010. Approximately 46% of the UK’s CO2

emissions is due to energy consumption in buildings, therefore,they can make a significant impact by achieving improved energyefficiency levels and reducing greenhouse gases and CO2

emissions.

In order to make the Alpha (a) value calculation, designerswill need the assistance of the envelope system manufacturer toevaluate condensation risk f-factor and measure linear thermalbridging heat loss Psi Value (Y) at junctions, etc. Any changes tospecification and construction of the cladding after the Alpha (a)value is calculated requires this value to be recalculated.

If the whole building Alpha (a) value is higher than 0.10 thebuilding fabric design and/or solutions have to be amended toachieve compliance.

The above values are obtained by finite element analysis basedupon the specific performance of Kingspan’s roof and wallsystems, and are available to designers on a project specific basis.

Construction details illustrated in this Design and ConstructionGuide include condensation risk f-factor and Psi Value (Y) data. Whole building Alpha (a) value examples are also indicated.

Step 3 - Building Envelope Specification PackageDesigners to specify roof and wall cladding systems which achieveParts L2 and J compliance and minimise heat loss at all junctionsand thermal bridges.

Detailed drawings should be provided for each part of the roof andwall system, including all junctions, penetrations, abutments,internal gutters, smoke vents, louvres, soakers, doors, windows,rooflights, curtain walling, brickwork and floor slab edge etc.

Kingspan, as a roof and wall system designer and manufacturer,provide a comprehensive package of construction details whichoptimise insulation continuity, f and Y values and incorporate airleakage seals for a range of different building purpose groups andapplications.

Our Technical Design Bureau will also develop projectbespoke L2 and J roof and wall systems solutions fordesigners and constructors.

Part L2 Building Regulations & Part J Standards Compliance in 7 Steps

Step 4 - ConstructionThe duties of the competent person(s) may be carried out by theconstruction team(s) or their advisers from step 4 onwards.The appointed competent person(s) are responsible for ensuringthe ‘approved design’ is built and workmanship quality achievescompliance. Should alternative roof and wall systems or productsbe substituted to that specified it is necessary that they areregulatory compliant.

Kingspan’s Parts L 2 and J construction details are robust anddesigned to be installer friendly, facilitating the achievement of highlevel workmanship quality and rapid installation speed.

Kingspan provide site support, training and advice to assistinstallers to achieve Parts L2 and J installation quality.

Step 5 - Materials & Workmanship QualityMaterials and workmanship quality to be inspected duringconstruction so that the competent person(s) responsible canprovide certification or declaration, following air pressurisationtesting and thermographic inspection survey (Part L2 only) thatthe roof and wall system complies with regulations.

Step 6 - Airtightness Testing (Part L2)On buildings of over 1000m2 floor area, an air leakage test hasto be carried out, to provide a declaration from a competentperson(s) that the test result demonstrates regulatory compliance.Alternatively for buildings of less than 1000m2 floor area adeclaration that appropriate design and installation has beencarried out to achieve conformity to specification.

Step 7 - Thermographic Inspection (Part L2)Appointed competent person(s) to certify that the design andinstallation provides the necessary regulatory insulation continuity.Alternatively implement a thermographic inspection survey by a competent person(s) to demonstrate that the insulation isreasonably continuous over the visible envelope of the buildingand excessive thermal bridging is minimised.

Note: Building Control should be asked to confirm inadvance who they consider is competent to complete the various declarations required before a completioncertificate is issued.

Failure to achieve regulatory compliance will result in projecthandover delays and subsequent rectification costs.
