Inspection, Service and Maintenance of Scaffolding Materials

Upon del ivery al l scaffolding mater ials are to be inspected for worthiness prior to use. Any defect ive i tems are to be quarant ined, and returned to the ya rd .

Incomplete Scaffold Notice

A prominent warning not ice indicat ing tha t a scaf fo ld , or par t o f the scaffold is not to be used is a f f ixed near any point wh ich the scaffold is l iable to be approached for the purpose of use, or access to the scaf fo ld , or par t .

The scaffold c rew shall ensure prominent warning not ices, and e f fec t ive ly block o f f access to those parts of a scaf fo ld which incomple te .

* Notices can be obtained f r om your supervisor, or yard fo reman.

Ties and scaffold stability

The scaffold f rame w i l l be t ied progressively w i t h the scaffold bui ld in accordance w i t h the proposed design reference TG20 13, and TG4:11. The t ie positions should be evenly d is t r ibuted over the scaf fo ld, both hor izontal ly and ver t ica l ly . Normal ly the spacing o f lines of t ies shall be not greater than 4.0m ver t i ca l . For Basic independent t ied scaffolds, the lines o f ties are f ixed e i ther at every l i f t or a t every other l i f t . A t least 50% of the ties is f ixed to the ledger-braced standards. The t ie tubes must extend across the inside and outside standards connected the by load bearing couplers.

Tying

*All bo l t f ix ing are instal led in accordance w i t h the manufacturer 's speci f icat ion, and NASC TG4:11. The t ies, and anchorage are selected in accordance w i t h the base mater ia l , and type of loading. The spacing in accordance w i t h the design a t 16sqm supported by prel iminary tests o f 5% of t ies insta l led.

Planning considerations and Procedures

The management have to ensure tha t work at height is p lanned, supervised, and carr ied ou t in a safe fashion. This would include emergencies and rescue si tuat ions. There is also a specif ic requi rement to consider the weather condi t ions.

* See the work at height section

To sure suf f ic ient qual i f ied CISRS Scaffolder 's at appropr iate levels (basic, advanced, e tc . )

If any trainees are involved they must be fu l ly supervised and thei r duties l imi ted to the level of thei r t ra in ing.

Page 7 of 22

Artelia_00010104 ART00006538 0007 ART00006538/7

When considered labourers they must never assist in erect ing e tc . , Scaffolding unless they are in a safe place, i .e. The ground or a fu l l y boarded and double guard rai led scaffold or other fu l ly protected place.

To ensure al l areas occupied by the company are keeping work area t idy and maintain access, do not int roduce t r ip hazards, i .e . , misplaced sole boards/prot ruding braces.

Training and Competence

The cont ract management must ensure tha t al l employees (including Management and Supervisory Staff) are deemed competent before al locat ing dut ies.

Al l scaffolding operat ives must hold the relevant Construct ion Industry Scaffolder 's Record Scheme (CISRS) card in the posit ion and duties they are permi t ted to per form e.g. Advanced Scaffoider, Scaffoider, Trainee Scaffolder 's, and Labourer. Copies of certs I cards at induction stage.

Working at Height

If wo rk has to be done a t height then suitable and suf f ic ient measure should be taken to prevent persons fa l l ing a distance where they are l iable to be i n ju red .

Where such measures do not remove the risk o f fa l l ing , then addi t ional measures must be taken to minimise the distance and consequences of a f a l l . Training and instruct ion must be provided in accordance w i t h NASC Safety Guide: SG4:10 Preventing Falls in Scaffolding.

Fall Prevention and Protection

Several propr ietary col lect ive fa l l protect ion systems recent ly in t roduced have become known as Advanced Guardrai l Systems' (AGS).

Advanced guardrai l systems provide col lect ive fa l l prevent ion for Scaffolder 's when traversing along a boarded l i f t , erect ing, a l ter ing, or dismantl ing scaf fo ld ing. These temporary guardrails remain in place wh i ls t the p la t fo rm guardrails are instal led or removed, al lowing Scaffolder 's to maintain guard rai l edge protect ion on working p lat forms a t a l l t imes.

Scaffold operat ives w i l l work in compl iance w i t h SG4:10 f rom above the base l i f t by maintaining the Scaffoider safe zone. Scaffolder 's shall instal l a min imum of a single guardrai l , a t least 950 mm above the p la t fo rm, on each face of the scaffold where a fa l l could occur.

The scaffold c rew w i l l ensure they work safely at al l t imes, and w i l l ensure that :

a. They work w i th in a "Scaf fo lder 's safe zone" as def ined by SG4:10, by using the advanced guardrai l or i f not pract icable, they must c l ip onto a suitable and suf f ic ient anchorage point w i th in I m f r om the leading edge, and remain c l ipped on , in those situations detai led in SG4:10, where i t is not pract icable to use co l lect ive measures - i .e. "Scaf fo lder 's safe zone"

Page 8 of 22

Artelia_00010104 ART00006538 0008 ART00006538/8

b. Rising and lowering boards f rom the p la t fo rm below in accordance w i t h the tunnel l ing method behind a min imum of a single guardrai l .

c. They only undertake tasks tha t they are competent to do.

d . Work to the RAMS a t al l t imes.

e. Personal fa l l protect ion equipment w i l l s t i l l be required to be used a t some point in the system of work unless every l i f t remains fu l l y boarded. When Scaffolder 's encroach f r om a Safe Zone' to w i th in one met re o f an unprotected area by guardrails they are considered a t risk' and personal fa l l p ro tec t ion equipment must be used. Where the Scaffolder 's safe zone extends beyond the bui lding l ine single ta i l Lanyard w i t h a 55 mm snap hook shall be used.

Adverse Weather

ASSL Contracts staf f w i l l br ief the Scaffolder 's tha t they must not work in adverse weather , wh ich w i l l a f fec t the safety of the scaffolding crew, operat ion, or tasks being undertaken, or stabi l i ty of l i f t ing operations e tc . , and must contac t the i r supervisor immedia te ly when bad weather approaches and seek advice. The scaffold crew must not egress the scaffold when thei r l ikel ihood of stormy weather could bring l ightening.

Supervision and Monitoring

ASSL shall provide adequate levels o f d i rec t supervision, as is necessary considering the complex nature or level of risk f rom the scaffolding operat ion, and the competence of the employees concerned. This may be a visi t ing role by a nominated Supervision as appropr iate to the task.

The visit ing supervision shall ensure al l personnel under the i r cont ro l are fu l l y aware of , and Instructed in the i r responsibil i t ies as imposed by regulat ions, codes o f pract ice, and NASC Guidance notes, company procedures, and take steps, so far as is reasonably pract icable, to ensure tha t they are proper ly imp lemented .

On-site Supervision

Each scaffolding crew w i l l have been appointed a nominated competent person (Lead Scaffoider) who shall set a personal example, to manage and imp lement the risk management of work act iv i t ies, or cont ro l risks to employees and tha t these assessments are communicated to al l those concerned.

Labourers and Trainee Scaffolder 's must work under the d i rec t supervision o f a competent Scaffoider. Note tha t Labourers are not permi t ted to work a t height unless safe access and egress and a safe working p la t fo rm has been provided. Trainees (I .e. CISRS Part 1 Trainee Scaffolder's) are only permi t ted to work at height under d i rec t supervision.

General duties of employees

Al l persons at work carry indiv idual responsibi l i t ies and these are out l ined in the Health and Safety at Work e tc . Act 1974, as fo l lows:

Distributing of Materials

In summary, a l l mater ials w i l l be d is t r ibuted f rom the parked vehicle and carr ied via hand to the work zone along the designated route. Al l materials w i l l be posit ioned to reduce the risk to persons behind a posit ive barr ier w i t h al l the relevant safety signs posted.

Al l employees shall assess al l handling act ion i n , wh ich a load is moved, posit ion or supported by physical e f f o r t . They are to ensure they only l i f t w i th in the i r own physical capabi l i t ies, always refer to team l i f t ing for anci l lary equipment . When transport ing anci l lary equ ipment i .e. prefabr icated beams, ladders e tc . , and two people may be needed to carry longer mater ia ls.

Only purpose made l i f t ing bags or baskets to be used for t ransport ing f i t t ings. The scaffold crew must always consider mechanical l i f t where possible.

Appropr iate good manual handling techniques (See Tasks Risk assessment of General Scaffolding Operations) are to be employed a t a l l t imes by the scaffold crew. Persons carrying mater ials a t shoulder height to keep the end of the tubes/boards t i l t ed down behind them to avoid causing in jur ies to others.

Manual handling

Key skil l

The special manual handling skil ls and techniques required by the scaffold c rew are covered as part of the Construct ion Industry Scaffolders Record Scheme (CISRS) for Part 1 , Part 2, and Advanced.

ASSL has opted to use shorter tubes for hemping standards a t height fo l lowing thei r own risk assessment, the tube length no greater than 5 .0 /16 f t . Whereas they st i l l rout inely use long tubes (6 .4m/21f t ) fo r ledgers, guardrails and standards at the base. Special considerat ion had to be given to the design of scaffolds and its locat ion.

The scaffold c rew is reminded to ensure appropr iate task re lated PPE is avai lable and used.

Rescue Procedures

Pre Rescue Act ion

If able to do so, the suspended casualty should be encouraged to use the fo l lowing techniques to reduce the risks f rom suspension t rauma:

If the person who is suspended is un- in jured and is fu l l y conscious, they should be encouraged to mobil ise al l four l imbs, i .e. by f lexing the leg muscles, unt i l they can be brought to a posit ion o f safety. This w i l l help to maintain the c i rcu la t ion.

Frequent 'pumping ' o f the legs against a f i rm surface w i l l also act ivate the muscles and improve blood c i rcu lat ion.

In the event a worker fal ls wh i ls t working on a fu l ly or part ly boarded scaf fo ld , and suspended at height in a safety harness, i t is essential tha t the suspended person to be rescued as soon as possible to prevent a condi t ion known as suspension t rauma. If they cannot reach the structure or rescue themselves, the rescue plan w i l l need to be e f fec t i ve to aid recovery.

Manual Handling Team Rescue

At no t ime should other Scaffolder 's endanger themselves in order to t ry to a f fec t a rescue. Scaffold operat ives w i l l be br iefed tha t they may a f fec t a rescue only i f the fa l len operat ive can be safely be l i f ted onto the boards by other scaffold operat ives situated behind a handrai l , c l ipped on , and working on a fu l l y boarded l i f t .

Rescue may be a f fec ted by the fo l low ing : 2no operat ives must grasp the fa l len operat ive and drag him onto the boarded p la t fo rm (ensuring tha t at al l t imes they do not put themselves at risk o f a f a l l ) . They w i l l cu t the lanyard, ensuring tha t i t is done safely, and the blade cuts away f rom the fa l len operat ive. The fa l len operat ive must be moved to a place of safety (i f pract icable) and to ld to rest in the recovery posit ion unt i l he has been medical ly checked for suspension t rauma. He may not return to work unt i l he has given his supervisor a medical note tha t he is we l l enough to work, and any re levant invest igat ion is concluded.
