Scope: This standard shall be applied to all works on new build and refurbishment projects within Qatar Foundation where work activities include the potential for fall from heights of personnel or equipment. All Contractors and Sub-contractors shall ensure that the content of this standard is understood and implemented at all times. 1. General 1.1. Fall protection is a primary consideration for all workplaces. The risk of a fall from height of personnel or equipment is ever present and this standard sets out mandatory controls that shall be applied in all Qatar Foundation places of work. No work shall commence where the risk of a fall from height is present. 1.2. Persons falling from height are the most common cause of major and fatal injury in the construction industry. The risk of a person falling from height occurs in many work activities such as: • • • • • • • • •

Scaffolding, false work and formwork erection Structural Steel erection Concreting and reinforcement work Roofing, cladding and glazing Excavation Crane rigging, erection, dismantling and maintenance. Lift and escalator installation. Mechanical and electrical services installation Maintenance and cleaning

2. Fall Prevention and Fall Arrest 2.1. The term Fall Prevention is used to describe any arrangements made that physically prevent persons from falling such as fully boarded work platforms, solid edge protection barriers, restraint systems etc. 2.2. The term Fall Arrest is used to describe any arrangements made that allow a person to fall and then arrests the fall before the person impacts any solid surface. 2.3. In each and every case of persons working at height the contractor will provide a means of fall prevention as the first priority. Only in cases where fall prevention arrangements are not practical will a means of fall arrest be used. 2.4. Where fall arrest systems are used the contractor will provide a method statement and job hazard analysis for the work activity. 3. Assessment of Work Activities 3.1. In the construction industry it is common for workers to interfere with protective measures. People put themselves and their colleagues at risk by removing or altering access equipment, guardrails / edge protection and hole covers. 3.2. The priority is to ensure that the protective measures used are those least likely to be interfered with. Secured boards covering a hole are superior to barriers or the use of a harness when considering protective measures for slab openings and risers for example. Barriers are easily removed and a harness may not be worn. 3.3. Elimination of the hazard shall be the first priority. The contractor shall carry out a risk assessment and ensure that work at height is eliminated as far as possible and adequate controls implemented where work at height must proceed. 3.4. When working at height cannot be avoided, the selected protective measures MUST consider a hierarchy of precautions – A safe working platform must be provided. If this cannot be achieved then alternatives may be considered. It is acceptable to refuse to carry out work where the risk of a fall is too great. Jobs must not be completed at all costs. 3.5. The protective measures selected shall be the strongest that is reasonable practicable giving consideration to risk and cost. 3.6. No work at height or where there is the risk of a fall from height shall commence without an assessment of hazards and consideration of associated risks.

4. Typical High Risk Locations 4.1. The risk of a fall from height will typically be increased when working on, in, or adjacent to the following locations detailed in the table below. The protective measure detailed shall be applied: 4.2. Work Situation

Recommended Protective Measures

Risers / Open Holes

Secured boards shall be used to completely cover openings. Covering shall be of such design as to allow persons and equipment to pass over or work above openings.

Site Example

Where hole covers are not possible, guardrails shall be installed. Form Work / Roof Work

Work shall not proceed on formwork until safe access / egress to the work area is provided. The work area shall have scaffold edge protection / guardrails. Where guardrails are not available lifelines shall be installed – refer to Section 5 of this standard for lifeline requirements.

Lift Shafts

Access to lift shafts shall be prohibited through the use of edge protection and toe-boards. No work shall proceed in a lift shaft unless a secure work platform has been provided.

Scaffolds

All scaffold systems shall be erected by a competent person in accordance with CSS 014, Scaffolders shall wear a harness and double tail lanyard at all times. When working in excess of 5m (or with 5m clearance) a shock absorber shall be worn.

MEWPs

MEWP’s are fitted with an anchor point for a restraint lanyard to prevent operators climbing out. All operators shall wear a harness and restraint lanyard. A fall arrest shock absorber will not be used. Users must not attach lanyards to structural points outside the equipment. Work areas below MEWPs shall be cordoned off to provide an exclusion zone to protect other parties from falling objects.

Excavations

Contractors shall ensure that hard barriers are in place for all excavations in excess of 1.5 meters deep. Refer to CSS 012 for further guidance.

5. Lifelines and Fall Arrest / Restraint Equipment 5.1. Lifelines shall be installed using a minimum wire rope size of 10mm or 5/8”. The lifeline shall be secured to a suitable and strong anchor point capable of withstanding a 1 tonne shock load. Lifelines shall have a minimum of 3 saddle clips installed over a 12” turnback and tightened using a turnbuckle. The maximum span of a lifeline will be 10 meters. 5.2. Issued fall arrest equipment will consist of a harness, lanyard with snap hook and detachable shock absorber. Fall arrest equipment (as opposed to restraint) shall be a last resort. 34 Procedure for Construction Site Safety Standards & Requirements for Contractors QF/HSSE/OHS /SOP-014 – Rev-0. June 2011 Copies other than electronic copies saved in the Qatar Foundation portal area are uncontrolled

The Contractors Project Management must consider alternative means of completing work without using fall arrest as the protective measure. The risk of falling from height should be eliminated or reduced. Harness

Lanyard with Shock Absorber Engaged / Disengaged

Snap Hook & Karabiner

Shock Absorber Engaged (Below)

Snap Hook

Shock Absorber Dis-Engaged (Below)

Harness Karabiner

5.3. Note the shock absorber type shown can be detached from the karabiner and re-attached to the karabiner at the opposite end to disengage the shock absorber from the lanyard. Depending on the length of the shock absorber, it must be disengaged when working below the shock absorber length + 3m (e.g. a shock absorber of 2m extension should be disengaged if working below 5m and a restraint lanyard only should be used. Lanyards with non-detachable shock absorbers must be removed from site or additional karabiners provided. 5.4. Inertia reel fall protection is an alternative option to disengaging shock absorbers or using restraint protection. Operatives issued inertia reels MUST be fully trained in their use and limitations. 5.5. Karabiners must be maintained. Dust and environmental conditions can cause the thread on the screwed gate of the mechanism to jam. Unscrew and test regularly. Do not use pliers to unscrew the gate, this will damage the mechanism and it may not unscrew when most needed.

Scope: This standard shall be applied to all excavation works on new build and refurbishment projects within Qatar Foundation. All Contractors and Sub-contractors shall ensure that the content of this standard is understood and implemented at all times. Requirements: 1. Introduction 1.1 The following guidance sets the Qatar Foundation standard for all excavation work. All contractors are required to meet or better this standard. The standard is not intended to specify excavation design detail which can be found in numerous industry standards or codes of practice, the intent is to define the way in which contractors will organize and manage their excavation operations. 1.2 The term excavation is used to describe any operation where the ground is removed by mechanical or manual means. The type of construction activities that normally involve excavation work are landscaping, site formation, foundations, drainage & underground services, basement structures and tunnel construction. 1.3 The main hazards associated with excavations are collapse; materials, people and vehicles falling into excavations; people being struck by mobile plant, equipment and vehicles; contact with existing underground services; collapse of adjacent structures, ingress of toxic fumes / gases and flooding. 1.4 Underground and overhead utilities may be encountered on or adjacent to the worksite. Utilities that may be encountered include: • • • • •

Electrical power lines Gas pipelines Water pipelines Sewers and drainage systems Communications and data cables 84

1.5 Such utilities may be hazardous if people, plant, equipment or materials come into contact with them. Additionally any damage caused to utilities may cause disruption to the worksite and surrounding area. 1.6 For all excavation activity a competent supervisor (engineer) will be appointed. The Competent Supervisor (Engineer) shall hold a valid 3rd party certificate for the design and inspection of excavations or valid civil engineering qualification. Note that major projects may require more than one Competent Supervisor (Engineer).

2. Excavation Design 2.1 Excavation design is driven by the size and shape of the ground formation needed for the works. However, in terms of ensuring the excavation safeties there are a number of other significant issues that need to be considered such as: • • • •

Geology and ground water. Adjacent structures, infrastructure, water courses and live services. Availability of space at the worksite. Contaminated ground.

2.2 Excavations up to 1.5m deep do not require a design; however, the requirements of this standard must be met during planning and excavation works. 2.3 Excavations in excess of 1.5m in depth, and any excavation work adjacent to existing structures, infrastructure, water courses and live services, shall require a design by the competent supervisor (engineer). The design shall specify the requirements for ensuring stability of the excavation such as benching and / or shoring. Excavations between 1.5m and 5m shall require daily inspection by the contractors site safety team or works supervisor. 2.4 Major excavation works, where excavations over 5m are required, shall require daily inspection by the competent supervisor (engineer). 3. Identification and Planning 3.1 The contractor shall ensure current utility drawings are secured and that devices such as a CAT (cable avoidance tool) are available to assist in the identification of existing utilities. Radiographic surveys may be required. Radiographic surveys shall only be carried out by a competent contractor approved for work in Qatar. 3.2 Where utilities are identified the hazards associated will be assessed and measures put in place to control any associated risk. The hierarchies of controls to be considered are: 85 Procedure for Construction Site Safety Standards & Requirements for Contractors QF/HSSE/OHS /SOP-014 – Rev-0.

5.4. Mandatory Slinging Methods Scaffold Tubes / Rebar Lengths When lifting bundles of tubes, bars or other loose materials, whether banded or not, slings should be double wrapped. Illustration shows slings in double wrap choke hitch and basket hitch. Note that a choke hitch will reduce the SWL by 20%.

Concrete Bucket Concrete buckets should not be lifted directly by the crane hook. A single-leg sling (commonly known as a drop or skip chain) should be used, as moving a heavy crane hook precisely into place can be difficult.

101 Procedure for Construction Site Safety Standards & Requirements for Contractors QF/HSSE/OHS /SOP-014 – Rev-0. June 2011 Copies other than electronic copies saved in the Qatar Foundation portal area are uncontrolled

Steel Sections / Beams Use double wrapped slings when sling legs can slide together.

Stillages Wrap slings round corner posts. Do not attempt to lift double stacked stillages.

Mesh / Pre-formed Rebar cages Welded Rebar Mesh Pass each hook of a four-legged chain through the mesh and return to form a choke hitch. Lifting points to be positioned evenly to prevent undue bending / twisting. Prefabricated Rebar Assemblies These assemblies rely on tying wire to hold them together. Attachment points MUST be determined by the Lifting Supervisor.

102 Procedure for Construction Site Safety Standards & Requirements for Contractors QF/HSSE/OHS /SOP-014 – Rev-0. June 2011 Copies other than electronic copies saved in the Qatar Foundation portal area are uncontrolled

Palletized Loads Pallet forks with safety netting should be used for blocks and other stacked materials than is delivered on a pallet. Note that the netting size should be smaller than the smallest item to be lifted.

Pipes For short pipes, pass sling through pipe. For long pipes, use two slings in choke hitch, double wrapping if slings are likely to slide together. Provided that no angle exceeds 90°, then use the SWL for one sling for the SWL of this arrangement. Note that a shackle is required to connect the slings at the top. If available, use pipe hooks / clamps for the end fittings of the lifting chain. Alternatively, a web sling can be used.

Lifting Points / Spreader Bars Many items of plant or prefabricated equipment (e.g. port cabins, compressors, skips etc) are provided with a certified, built in lifting point. Lifting points should be used with 2 or 4 leg chains. Attachment points MUST be determined by the Lifting Supervisor. Where items may bend or twist, a spreader bar or lifting beam shall be used.

Approved By

Kevin Murray HSE Manager HSSE Directorate

Date

20/05/2011

Scope: This standard shall be applied to the selection, design, erection, use, alternation and dismantling of scaffold and associated ladders and stairs. This standard does not apply to false work / form work support scaffold which is covered in CSS 004. This standard applies to all works on new build and refurbishment projects within Qatar Foundation. All Contractors and Sub-contractors shall ensure that the content of this standard is understood and implemented at all times. Requirements: 1. Introduction 1.1. The following guidance sets the Qatar Foundation standard for scaffolding. The guidance is not intended to specify scaffolding detail which can be found in numerous industry standards or codes of practice, the intent is to define the way in which contractors will organize and manage their scaffolding operations on the Project. 1.2. Scaffolding has a variety of applications such as construction, alteration, routine maintenance and renovation work. Properly erected and maintained scaffolding provides employees with safe access to work locations, level and stable working platforms, and temporary storage for tools and materials. 1.3. Accidents involving scaffolding mainly involve people falling and falling materials. The causes of scaffolding accidents include failures at support & attachment points, parts failure, inadequate fall protection, misuse of fall arrest equipment, improper construction, environmental conditions and overloading. 2. Scaffolding Selection 2.1. There are numerous types of scaffolding commonly used in the construction industry and it is a fundamental safety requirement to select the correct type for the work required. There are many factors that determine suitability; the most common are listed below; •

duration and type of tasks to be performed from the scaffolding 105

Procedure for Construction Site Safety Standards & Requirements for Contractors QF/HSSE/OHS /SOP-014 – Rev-0. June 2011 Copies other than electronic copies saved in the Qatar Foundation portal area are uncontrolled

• • • • • •

number of people required to perform the tasks height and size of the elevated working area the force of the loads to be supported weather and environmental aspects proximity of other hazards ground or support structure

2.2. Once the factors are clearly determined the selection of suitable scaffolding can be made. 3. Scaffolding Design 3.1. When a suitable scaffolding type has been selected it must then be properly designed. Suppliers and manufacturers of system scaffolding will provide specifications for the use of their equipment and designers must always follow the specifications. 3.2. Where necessary the suppliers and manufacturers can be consulted to ensure that their equipment is suitable for the intended use. Other scaffolding may be uniquely designed in accordance with an industry standard or a code of practice to suit the work requirements. 3.3. There are three basic requirements to ensure that scaffolding is properly designed for the intended use. Firstly it must be designed to be capable of withstanding its own weight and that of the static loads that may be imposed on it, such as materials and equipment. Secondly it must be designed to withstand the force of any dynamic loads that may be imposed on it, such as wind, movement of materials or movement of the scaffolding itself. Thirdly all imposed loads must be given a factor of safety to provide a safe working load for the scaffolding. Maximum Static Load + Maximum Dynamic Load + Factor of Safety = Safe Working Load 4. Competent Supervisor 4.1.1 For all scaffolding erection / dismantling activity a competent scaffolding supervisor will be appointed. The Competent Supervisor shall hold a valid 3rd party certificate for the design, erection and inspection of scaffolding. Note that major projects may require more than one Competent Supervisor. 4.2 Known Design 4.2.1 The Competent Supervisor will be in advised in advance by the contractor ‟s project engineer of the loading requirements and task for which the scaffolding is to be constructed. 4.2.1 The information must be clearly understood by the Competent Supervisor prior to any erection activity being undertaken, should there be any areas of doubt the scaffolding supervisor will seek clarification. This shall be especially pertinent for complex requirements e.g. suspended scaffolds, cantilevers and loading bays. 106 Procedure for Construction Site Safety Standards & Requirements for Contractors QF/HSSE/OHS /SOP-014 – Rev-0.

Substitution of components shall invalidate the inspection concessions set out in 7.5 of this procedure. 7.4. Safe System of Work for Erection, Dismantling or Alteration of Mobile Aluminum Scaffolds 7.4.1. The use, by erectors, of a safety harness with a restraint lanyard attached to the tower scaffold is not an acceptable safe system of work when constructing a mobile aluminum scaffold. In the event of a fall the scaffold is likely to overturn as a result of the shock load, increasing the risk and severity of injury, not only to the user but also to those at ground level. 7.4.2. A safer method for the safe erection / dismantling of mobile aluminum scaffolds is the „Through the Trapdoor ‟ method. Below is an example of this method;

At no time should erectors be on the outside of the scaffold. Where the working platform is greater than two lifts, a rest or mid platform should be installed (Note that Contractors shall consult the manufacturer’s specified requirements for exact details). Towers with a working platform in excess of 3m shall have stabilizers fitted. Towers with a working platform of 8m or more should change stabilizers for extendable outriggers (Note that Contractors shall consult the manufacturer’s specified requirements for exact details).

7.5. Inspection of Mobile Aluminum Scaffolding 7.5.1 The use of a scaff-tag system for mobile aluminum scaffolds with a working platform of less than 3m is not mandatory. The scaff-tag system shall be applied to all mobile aluminum scaffolds in excess of 3m. 111 Procedure for Construction Site Safety Standards & Requirements for Contractors QF/HSSE/OHS /SOP-014 – Rev-0. June 2011 Copies other than electronic copies saved in the Qatar Foundation portal area are uncontrolled

7.5.2. Should substitute components be used in the erection process then the scaffold shall be subject to a formal inspection and scaff-tagging by a competent person. 7.6. Use of Incomplete Mobile Aluminum Tower Scaffolds 7.6.1. In certain circumstances it will be acceptable to use a mobile tower scaffold that is incomplete. This will only apply where the top guardrail cannot be attached due to an obstruction such as pipe work, ductwork or containment work. In these circumstances users of the mobile scaffold tower must use a harness and lanyard. 7.6.2. The lanyard must be attached to a secure anchor point, NOT the mobile aluminum scaffold itself. The anchor point must be able to take the shock load of a falling person. 7.6.3. Shock absorbers must be removed or disengaged where insufficient clearance exists. Typically with a 2m shock absorber, a clearance of 5m would be required. 8. Podium Steps and Specialist Working Platforms 8.1. Contractors are encouraged to purchase and use Podiums steps and other bespoke solutions that are manufactured to relevant international standards. 8.2. The use of a scaff-tag system for podium steps and specialist working platforms with a working platform of 3m or less is not mandatory. 8.3. Should substitute components be used in the erection process then the podium step / specialist working platform shall be subject to a formal inspection and scaff-tagging by a competent person.

Qatar Foundation – Construction Safety Standard CSS 015 Subject:

Confined Space Entry

Prepared By

Paul Maclean Head of Safety

Date

15/05/2011

Approved By

Kevin Murray HSE Manager HSSE Directorate

Date

20/05/2011

Scope: This standard shall be applied to all Confined Space Works on new build and refurbishment projects within Qatar Foundation. All Contractors and Sub-contractors shall ensure that the content of this standard is understood and implemented at all times. 1. General 1.1. Confined space work is dangerous because often there are no apparent signs of danger and rescuing a worker who needs help is usually difficult. 1.2. All existing hazards in confined spaces must be thoroughly evaluated prior to each entry into the space and monitored continuously thereafter. 1.3. The work to be performed in the confined space will be evaluated to ensure that it will not pose an undue hazard for the duration of the work. 2. Definition and Key Terms 2.1. For the purposes of this standard, a „Confined Space ‟is any space of an enclosed nature where there is a risk of death or serious injury from hazardous substances or dangerous conditions (e.g. lack of oxygen). A confined space has limited or restricted means for access / egress restricts the natural movement of air and is not designed for continuous employee occupancy. 2.2. Typical confined spaces are shown below:

113 Procedure for Construction Site Safety Standards & Requirements for Contractors QF/HSSE/OHS /SOP-014 – Rev-0. June 2011 Copies other than electronic copies saved in the Qatar Foundation portal area are uncontrolled

Manhole

Sump

2.3. Examples of confined spaces that may be encountered on Qatar Foundation include: manholes, sewers, sump pits, storage tanks, boilers, ventilation or exhaust ducts, underground utility chambers, tunnels and trenches. It is not possible to provide a comprehensive list of confined spaces. Some places may become confined spaces when work is carried out, or during their construction, fabrication or subsequent modification. 2.4. While there are numerous hazards relating to confined spaces the principal hazard of a confined space is the presence of a toxic or hazardous atmosphere where workers may be at risk due to: • • • •

Flammable gas, vapor, or mist Airborne combustible dust Atmospheric oxygen concentration below 19.5% or above 23.5%; Any other atmospheric condition that is Immediately Dangerous to Life or Health (IDLH)

2.5. IDLH - Immediately Dangerous to Life or Health; means any condition that poses an immediate or delayed threat to life or that would cause irreversible adverse health effects or that would interfere with an individual ‟s ability to escape unaided from a space. 2.6. It should be noted that hazardous substances that are produced by activities in the general area of a confined space can migrate to and accumulate in the space creating an unseen hazard to an unsuspecting entrant. 3. Competent Supervisor 3.1. The contractor shall appoint a „Competent Supervisor ‟ for all confined space works. The Competent Supervisor shall hold 3rd party training and certification and shall be present on site to manage confined space entry activities. 3.2. The Competent Supervisor shall be appointed in writing and shall be specifically named and referred to in any method statement prepared for confined space work. 3.3. The Competent Supervisor shall: •

Identify „Confined Spaces ‟

• •

Identify personnel who will enter confined spaces Provide detailed instructions and training on confined space hazards and entry procedures Evaluate respiratory hazards and train personnel on routine measurement of respiratory hazards Provide instruction to personnel on the proper use of equipment for confined space entry

• •

114 Procedure for Construction Site Safety Standards & Requirements for Contractors QF/HSSE/OHS /SOP-014 – Rev-0. June 2011 Copies other than electronic copies saved in the Qatar Foundation portal area are uncontrolled

• • • • •

Maintain equipment that is used to enter and monitor confined spaces Maintain records of equipment maintenance and employee training Establish an entry permit system for entering confined spaces Establish non entry and entry rescue systems Conduct pre-entry briefings to inform entrants of the possible hazards that may be encountered

4. Hazard Identification 4.1. The contractors shall carry out and document a detailed hazard assessment and develop a safe system of work (SSW). A detailed method statement shall document the SSW for specific tasks and shall incorporate atmospheric testing, training and instruction, hazard controls, entry procedures and emergency / rescue procedures. 4.2. Typical hazards are: 4.2.1. Atmospheric – Asphyxiating, Flammable and Toxic atmospheres. 4.2.2. PhysicalMoving machinery, falls, electrocution, noise, heat, engulfment. 4.3. The contractor shall control atmospheric hazards by: • Carrying out atmospheric testing • Ventilating the confined space for a minimum of five (5) minutes • Continually retesting the atmosphere to confirm that acceptable entry conditions are present • Appointing a confined space standby operative to monitor the job at all times • Setting up non-entry rescue equipment and entry rescue equipment

The contractor shall set up rescue equipment such as a tripod winch prior to commencement of works (refer to section 7 of this standard). The contractor shall set up a fan with flexible hose (as shown) to ventilate the confined space 4.4. The contractor shall control physical hazards by: 115 Procedure for Construction Site Safety Standards & Requirements for Contractors QF/HSSE/OHS /SOP-014 – Rev-0. June 2011 Copies other than electronic copies saved in the Qatar Foundation portal area are uncontrolled

• Locking out electrical sources at switches that are remote to the space • Bleeding pneumatic and hydraulic lines • Disconnecting mechanical linkages and belt or chain drives • Securing mechanically moving parts with chains, blocks, or other devices • Plugging pipe inlets / outlets • 5. Atmospheric Testing 5.1. Atmospheric testing will be required to confirm acceptable entry conditions. Atmospheric testing shall only be carried out by a competent person. Acceptable entry conditions will meet the following basic requirements: • • • •

Oxygen (O2 ) – greater than 19.5% and less than 23.5% Lower Flammable Limit LFL – less than 10% Carbon Monoxide (CO) –less than 35ppm Hydrogen Sulphide (H2 S) – less than 10ppm

5.2. The multi-gas monitor used must automatically alarm if any of the above values are exceeded. The multi-gas monitor must be calibrated and certificates available to ensure correct readings. 5.3. Where any other toxic or hazardous substance is present, or has the potential to be present, the proper monitoring equipment will be obtained and operated by an individual who has been trained in its use. 5.4. The confined space will be periodically monitored by the competent supervisor to ensure that acceptable entry conditions are being maintained throughout the entry operation. 5.5. If conditions deteriorate during entry, all entrants will exit immediately and the method of work will be re-evaluated. 5.6. If acceptable entry conditions cannot be maintained with continuous forced ventilation (for example in live sewer lines), never try to sweeten the air with pumped oxygen. This can lead to build up of oxygen presenting an explosive atmosphere. 5.7. In situations where acceptable entry conditions cannot be maintained there will be a requirement for personnel to wear Respiratory Protective Equipment (RPE) or Self Contained Breathing Apparatus (SCBA). Personnel required to carry out this type of operation will need to have undergone training in use of RPE or SCBA. The appointed competent supervisor shall ensure that personnel are trained and are suitably healthy to undertake the work required. 116 Procedure for Construction Site Safety Standards & Requirements for Contractors QF/HSSE/OHS /SOP-014 – Rev-0.

6. Confined Space Entry Equipment 6.1. Each site will make available any equipment necessary for entry into a confined space. This shall include but is not limited to: • • • • • • • •

Testing and monitoring equipment Ventilation equipment Communications equipment Personal Protective equipment (PPE) / Respiratory Protective Equipment (RPE) Lighting / Signage / Barriers / Fencing Ladders Specialized tools (e.g. Intrinsically safe tools and lighting for flammable atmospheres) Non-entry rescue, entry rescue and emergency equipment.

6.2. All equipment will be maintained and supervisors will ensure that employees use the equipment properly. 7. Rescue and Emergency Services Procedure 7.1. Under no circumstances must unauthorized personnel enter a confined space to attempt a rescue. 7.2. Site staff / operatives can facilitate non-entry rescue using a planned retrieval system. A non entry retrieval system should consist of a chest or full body harness with a retrieval line attached at the centre of the entrant ‟s back near shoulder level, or above the entrant ‟s head. 7.3. The retrieval line will be attached to fixed point outside the confined space so that rescue work may immediately commence if necessary. 7.4. For vertical spaces that are more than 2m deep, a mechanical device, (tripod with a hoist), will be made available to retrieve personnel (as shown in 4.3 of this standard). 7.5. It is likely that some entrants to confined spaces are not able to have a revival line attached. This may be the case in tanks where distance and layout limit the use of a lifeline. In such circumstances rescue procedures need to be clearly defined prior to work commencing. The entrant shall still wear a full body harness as retrieval is made easier in most circumstances. 7.6. Where rescue procedures require entry of rescue personnel, this must be reflected in the works method statement. Those designated for rescue duties shall be fully trained in the use of Respiratory protective Equipment (RPE) or Self Contained Breathing Apparatus (SCBA) and 117 Procedure for Construction Site Safety Standards & Requirements for Contractors QF/HSSE/OHS /SOP-014 – Rev-0. June 2011 Copies other than electronic copies saved in the Qatar Foundation portal area are uncontrolled

shall be physically capable of performing such duties. Note that the first duty of rescue personnel is to avoid becoming a casualty themselves. 7.7. No confined space work shall commence without the relevant personal and equipment, including rescue equipment being in place at the worksite. 7.8. Qatar Foundation Emergency Services and Civil Defense Emergency Services shall be included in all contractors’ emergency procedures. 7.9. Qatar Foundation Emergency Services can provide ambulance services from CP2 and can attend site in the shortest time. Additional Ambulance services and Fire Services are available from Civil Defense. The relevant contact numbers to be included in any contractor’s emergency plan are: Qatar Foundation Emergency Services
