    Control Measures
    1Planning: Sufficient numbers of trained operatives and competent supervision must be available before work starts.  Sufficient and suitable plant must be available for trench support before work starts.  Suitable monitoring equipment and personnel trained in its use will be required where known exposure to toxic substances or lack of oxygen may occur.  Location of existing services must be complete before work starts, also information obtained on ground conditions from site surveys. Load weights and SWL of lifting equipment to be confirmed as compatible and within test  
    2Physical: Sides of excavations likely to collapse must be supported.  Where flooding risk exists, cofferdams/caissons will be installed with pumps of suitable capacity. Substantial barriers will be erected around excavations greater than 2m deep. Where poor ventilation is identified the atmosphere will be continually monitored.  Stop barriers will be used to prevent vehicle entry.  Spoil and materials will be stacked back at minimum of 1M from the edges of excavations.  Ladders will be provided for safe access/egress.  Cable location devices (C.A.T.) and client / Local Authority drawings will be used to trace buried services prior to commencement of work.  Suitable signs and barriers will be provided to warn of the work.  
    3Managerial/Supervisory: Ensure safe system of work provided, taking account of prevailing conditions including weather, traffic and existing structures.  Provide suitable PPE as required and ensure its correct use.  Inspect supported excavations before each shift, and record details, also following any destabilising event or fall of material.  Ensure personnel selected are capable, fit and experienced unless under direct supervision.  COSHH assessments are to be made of substances likely to be found used or produced during the work.  
    4Training: Supervisors must have received training in COSHH appreciation, general site safety, theory and practice of excavation work.  Operatives must have received training in excavation support procedures and use of cable location devices.  This applied to sub contractors as well as direct employees. Toolbox talks on Excavation work, MHO’s and COSHH will be given at regular intervals.

    1. Purpose
    1. Aviation and Operational Safety during construction is the primary consideration in developing a work plan for the Pavement and Utility Infrastructure Construction at the Taxiway Lima intersection to Existing Runway 13R-31L and Taxiway Zulu.  The objective of this Method Statement for Airside Operational Area (AOA) safety during construction is to identify site specific considerations and establish security and safety performance standards to be implemented during the execution of the constructions activities adjacent to and within the Airside Operational boundary.
    • Project Overview

    2.1       Project Location

    The Taxiway Lima intersection to Existing Runway 13R-31L is as shown on Halcrow Drawing No. PGAD 745/1008/C/138, Revision E.  Construction activities will be confined to the area within the Airside Operational Area, North of Taxiway “Z” (Zulu), westerly to the limits of work adjacent to Taxiway Lima, and easterly to the limits of work adjacent to Taxiway Kilo. The northerly limit as described is bound by the alignment of the Stage 1 temporary and interim fence at approximately 2165 N, or 165 meters north of the Existing Runway 13R-31L centerline.

    A planned intersection to Existing Runway 13R-31L at Taxiway Mike (14) will not be constructed at this time.

    • Scope of Work

    The construction activities to be performed within the above-described work locale include:  

    • Trial excavation for existing utility verification and documentation; protection of existing services.
    • Excavation to formation levels.
    • Haulage of excavated materials from within the AOA to adjacent or landside disposal.
    • Excavation and installation of future use communication and AGL lighting ducts via conventional cut and cover methods.
    • Aerodrome transformer housing pits, blinding, and surrounds.
    • Formation level earthworks, grading and compaction.
    • Select fill placement, sub base grading and compaction including prime coat application.
    • Milling of existing bituminous surfaces, new bituminous pavements, markings, and barriers.
    • Installation of AGL secondary ducts (AGL lighting works by others).
    • Work Considerations / Operational Restrictions

    Airport operational restrictions will be implemented during the execution of the construction activities for the Taxiway Lima crossing.  Existing Runway 13R-31L will be closed daily during execution of works within 75 meters of the Existing Runway centerline for a “Curfew Period”, identified to be from 0330 hours (3:30AM local time) to 0700 hours (7:00 AM local time).  Duration of the period within which these works will be carried out is from 30 October, 2007 thru 7 December, 2007.

    Due to the runway closure, weather or wind conditions should not impact the Contractor activities during the “Curfew Period”.  Should low visibility conditions arise, the Contractor operations will be allowed to continue by ADIA Air Traffic Control (ATC), with additional due diligence to the cleanup and inspection processes required prior to the resumption of normal activities being allowed by Air Traffic Control.

    Other Airside Operational Safety considerations necessary to the execution of these Construction activities and to be addressed in this statement include:

    • Communication/procedures with Abu Dhabi International Airport Company (ADAC), ADIA Air Traffic Control (ATC), ADIA Fire and Rescue, and other Airport Operators.
    • Access control and security measures.
    • Maintenance of Airside Security Boundary integrity.
    • Clear delineation of construction limits and boundaries, as well as, haul routes for construction and inspection access and egress to the zone.
    • Foreign Object Debris (FOD) and dust control measures, as well as, cleanup of haulage routes.
    • Observance of traffic movements within ADIA regulations.
    • Construction hours of operation.
    • Taxiway Lima access to Gulf Aviation Maintenance Company (GAMCO).

    • Construction Vehicle and Equipment Markings

    OAJ-JV vehicles and equipment shall have identification markings, registration, and be in accordance with ADIA regulations.  Vehicles and equipment will be deployed with flashing safety lights, as required.

    • Radio Communication in Movement Areas

    Taxiway Lima crossing of Existing Runway 13R-31L is defined on Halcrow Drawing No. PGAD 745/1008/C/138, Revision E.  Portions of the work area will remain closed via NOTAM throughout the work period.  Radio communication with the ATCT will be necessary to coordinate construction movements within this work area.

                7.2.4    Escort Procedures for Construction Vehicles in Movement Areas

    Taxiway Lima crossing of Existing Runway 13R-31L is defined in Halcrow Drawing No. PGAD 745/1008/C/138, Revision E.  Portions of the area will remain closed via NOTAM.  It is anticipated that escorting of construction vehicles or equipment will be necessary within this work area.  Access to the areas from the south will be via the existing interior service roads.  Access from the north of the existing Runway 13/31 will be via newly installed Security Gate No. 11.

                7.3       Maintenance of Airside Security Boundary

                7.3.1    ADIA Security Check Point Gate 1 and Gate 11

    OAJ-JV will utilize existing ADIA Gate Nos. 1 and 11 as the main points of access to the work zones.  All requirements of DCA and the ADIA Police regarding access controls will be observed.

    • Fencing and Gates

    Taxiway Lima crossing of Existing Runway 13R-31L work area is bound by an existing temporary and interim AOA security fence, including the segment north of the existing runway installed during Stage One.  No change to this alignment is anticipated.

                7.4       Delineation of Construction Boundaries

    • Hazardous Area Identification / Barrier Closure

    The Taxiway Lima crossing of Existing Runway 13R-31L boundary used to identify the area where no aircraft traffic will be permitted will be formed using a water-filled plastic barrier.  The barricades will be alternating red and white in color, supplemented with red flags, and spaced across the paved surface to create an identifiable physical barrier indicating the closure of the area to Operator use.  Warning lights, flashing red, and stand mounted will be either battery operated or existing circuit powered, if possible.  Stands will be properly secured to the existing surface to avoid overturning.

    In support of the areas that will remain closed during the construction period, existing taxiway lights and signs that may be potentially lead an aircraft into the closure barriers will be de-energized, if possible, or covered and masked.  OAJ-JV will request the assistance of the operations and maintenance staff in identification of the lighting circuits to determine the methodology necessary, and the limits required by Airside Operations.

    To further support safe execution of the construction activities within the work zones, OAJ-JV will constrain activities to areas outside the Taxiway Safety Area (47.5 meters from the centerline) during periods of reduced or Low Visibility (LVO), as directed by Air Traffic Control.

    All works within 75 meters of the Existing Runway 13R-31L centerline will be considered to be performed under curfew conditions, requiring closure of the runway for construction access.  As such, no reduced or Low Visibility (LVO) considerations are necessary, in accordance with Annex “A”.  Specific timing of this period is identified as in Section 2.3, Work Considerations / Operational Restrictions.

    • Maintenance of Taxiway Safety Areas and Object Free Areas

    The Taxiway Safety Area is defined as a parallel line 47.5 meters from the centerline of the facility.  The runway safety area is defined by a parallel line 150 meters from the centerline of the facility. This line will be demarcated by wooden stakes and flags marked along the boundary.  This will serve as a hold point for Contractor traffic.  No storage of Contractor materials or plant will be allowed within this area.

                7.4.3    Protection of Existing Navigational Aids

    Zone One navigational aids include existing equipment in operation at the Meteorological Station and existing taxiway signage.  A barrier will be placed, as necessary, to prevent potential damage from any unwarranted access.

                7.4.4    Protection / Relocation of Existing Services

    OAJ-JV will identify existing services by means of trial exploration.  Survey data collected as a result of the excavation will be mapped in accordance to requirements of the Contract and presented to the Engineer. Modification of existing services to be included in the scope of work is yet to be defined.

    • Contractor Storage of Equipment and Materials

    OAJ-JV Drawing No. OAJ/1008/C/AF/SD/176/215 indicates the staging areas to be utilized during the construction.  Contractor’s access routes and site utilization plans will at all times be managed so to minimize the impact of the construction activities to Airport Operations.  OAJ will receive materials to be incorporated into the work and hold in the staging locations for transportation into the work zone, as necessary.  Mobile equipment will be extracted to landside areas during idle periods and track equipment will be moved to areas identified to be clear of runway and taxiway safety areas.  The objective is to reduce the necessity for staging within the AOA environment to the greatest degree possible.

    • Taxiway Lima Activities and Communication with Gulf Aircraft Maintenance

    Company

    Taxiway Lima, south of Taxiway “Z” (Zulu), will serve as access to GAMCO.  Taxiway Lima in this area will be maintained so to allow 24-hour access, under tow-in and tow-out conditions as required by the Contract.  OAJ-JV will manage coordination with GAMCO, as necessary, during planning and implementation of construction activities that may impact movement; either scheduled or emergency, to or from the Operator’s facilities.  No impact to the GAMCO facility operations is anticipated.

                7.5       Foreign Object Debris (FOD) Elimination

                7.5.1    Work Zone Cleanliness Management

    OAJ-JV will maintain a team, consisting of supervision, labor and equipment, responsible for work zone safety and cleanliness.  Duties, on a 24-hour basis, as necessary, will include maintenance of the closure barriers, debris elimination, washing, and vacuum sweeping of the work zone.

                            7.5.2    Contractor Haul Route Maintenance

    OAJ-JV Drawing No. OAJ/1008/C/AF/SD/176/215 indicates the planned routes for access to and from the work zone.  OAJ-JV will maintain these routes free from construction generated dirt and debris by means of washing and vacuum sweeping.

                7.5.3    Contractor Staging Area Housekeeping

    OAJ-JV will maintain a team, consisting of supervision, labor, and equipment responsible for staging area safety and cleanliness. The team’s responsibility includes maintenance of the staging area fence and barriers, debris elimination, trash disposal, and watering and dust mitigation within the area.

    • Dust Control

    Mitigation of dust generated by construction activities is of primary concern to OAJ-JV.  Dust control will be achieved by consistent and continuous application of water to all areas including those where excavation and grading proceed, as well as, along routes where construction traffic is moving and Contractor materials and equipment are to be staged.  No work will proceed without provision for control of dust in place.

    • Construction Traffic Plan and Control Measures

    OAJ-JV Drawing  No. OAJ/1008/C/AF/SD/176/215  indicates the planned routes for access to and from the work zone identified in support the NDRC directional drilling works.  Access to the Taxiway Lima intersection work locations will be the same.

    Where possible, appropriate traffic control and identification signs will be placed along the routes to enhance construction traffic movement.  Directional, speed control, and construction area identification signage is planned to be placed at critical locations to increase awareness and reduce impact to the traveling public and ADIA Operator personnel.

                7.8       Contractor’s Hours of Operation

    Due to the time critical nature of the construction activities required for the Taxiway Lima intersection to the Existing Runway 13R-31L, it is mandated that the Contractor hours of operation will be to the maximum amount allowed by the Abu Dhabi Airport Company (ADAC) and the Air Traffic Control Tower.  Final determination states that the Contractor’s construction program, for works within the “Curfew Area” defined as 75 meters either side of the Existing Runway centerline, will be allowed beginning 30 October, 2007 thru 7 December, 2007. Work hours where the Existing Runway 13R-31L will be closed for construction access will be from 0330 hours (3:30 AM Local Time) to 0700 hours (7:00 AM Local Time).

    Works in adjacent areas, but outside the “Curfew” limitations, will proceed as allowed by prior approved Permits to Work, and continues throughout the period under normal daytime operations.

    • Responsibilities

    8.1       The CM will coordinate with the ACM and ensure that the necessary resources to implement the approved method statement, and job and activity hazard analysis have been allocated to the task.

          8.2       The ACM, along with the PE/SE, will ensure that the site preparation activities are conducted according to the approved method statement, JHA, AHA, and all in-situ tests as required in the ITP are implemented.

                8.3       The ME is to ensure the materials being used are in accordance to the project specifications, the approved method statement, and the ITP.

                8.4       It is the Site Supervisor’s responsibility to organize the work in a safe manner and ensure that safety and protective equipment are being properly utilized. The Site Supervisor must also ensure that the AHA and JHA are implemented, the method statement procedure is followed, and the ITP is applied.

    • Annex “A” – Air Traffic Control (ATC) – Runway Curfew Procedures

    The following Plan of Action has been developed by the Abu Dhabi Airport Air Traffic Control (ATC), and will be implemented by OAJ-JV during execution of the works to be performed under the Curfew restriction.  This procedure is set so as to define the actions required by all during the execution of the construction activities required for the connection of Taxiway Lima to Existing Runway 13R–31L.

    Prior to the Work:

    • ATC shall issue a Notice to Airmen (NOTAM), identifying the works to be entertained throughout the Curfew Period.  Existing Runway 13R–31L will be closed from 30 October thru 7 December, 2007 from 0330 hours to 0700 hours, local time.
    • Beginning on 27 October 2007, information regarding the Existing Runway 13R-31L closure will be placed on the ATIS, as a reminder.  From 29 October 2007, NOTAM stating “RUNWAY CLOSED” will be put on the ATIS from 2 hour prior to the Curfew, until resumption of normal operations.
    • ATC shall consider the “Runway Closed” throughout the period, as defined above.
    • Should any particular shift require that no work be performed, OAJ-JV Supervision will notify the ATC Supervisor as such. Inspections will be conducted as required by the ATC Supervisor.

                During the Work:

    • ATC shall close the runway as close as possible to 0330 hours, 3:30 AM, local time.
    • ATC shall identify during the period of Curfew that any Aircraft that may declare an emergency use Abu Dhabi International Airport as a last resort alternative.  It is understood that it will take no less than 30 minutes for clearance of the work area and performance of a complete inspection of the work area and the Runway, prior to any landing.
    • OAJ-JV Supervision will contact the ATC Supervisor no less than 30 minutes prior to the beginning of the Curfew, to confirm that the work parties are prepared.
    • Curfew shall commence ONLY AFTER CLEARANCE IS RECEIVED BY OAJ-JV SUPERVISION FROM THE ATC SUPERVISOR.
    • Curfew work will continue as normal during periods of low visibility (LVP) occur.  ATC Supervisor and OAJ-JV Supervision will exercise vigilance during the cleanup process and in inspection prior to the runway being declared open for use.
    • After issuing the clearance to proceed, ATC will inform the AGL Section to switch off all Runway lighting during the remainder of the Curfew period.
    • OAJ-JV shall place one(1) portable lighted cross at each end of the runway, as an added precaution during the remainder of the Curfew period.
    • Existing frangible barriers at Taxiways Lima/Kilo will be moved or removed as necessary to support the works, and will be replaced prior to the resumption of normal operations.
    • OAJ-JV shall insure that all construction plant and personnel have vacated the Runway, to beyond the designated 75 meter offset to centerline, upon completion of each Curfew shift.
    • OAJ-JV supervision shall contact the ATC Supervisor toward the end of the Curfew Shift, as the cleanup starts. Such communication will allow ATC Supervision sufficient time to perform an inspection of the curfew works area and a full runway inspection.
    • Upon direction from the ATC Supervisor that the inspection has been completed, OAJ Supervision will notify ATC via telephone that the Runway is clear and available for use.
    • Handover of the Runway, before and after the nightly Curfew, shall be done directly between the ATC Supervisor and OAJ-JV Supervision. This will be done via a recorded phone line, with Runway Closed or Runway Open being written in the ATC Log Book.
    • Signed certification or statement will be required from ATC to ensure that the temporary closing and opening will be conducted in accordance with ATC regulations and procedures, and actions will be taken to prevent damage to airport and facilities and an inspection of airport movement area will be carried out by ATC in coordination with the contractor prior to opening the runway.

    Manual Handling
    COSHH

     

    Manual Handling

    We lift, manoeuvre and handle goods every day of our lives in one way or another, not just whilst at work but also during social activities such as gardening, DIY, shopping and sport.

    A bad back or injury today, could, and regularly does, turn into a painful back problem for life!

    Lifting incorrectly could also lead to a hernia, sprains, strains and even fractures.  Therefore, before lifting items take a few seconds to think – it could save a lot of pain!

     

    Lifting safely

    • Can a trolley or mechanical lifting aid be used to lift the item instead of handling the item manually?
    • Be kitted-up for the job and, if practicable, obtain firm – grip gloves.  The gloves will also offer protection against cuts, punctures and friction burns.
    • Wear safety shoes to ensure a good floor – surface grip to prevent slipping whilst manoeuvring. The shoes will also provide protection from falling objects.
    • Before lifting assess the weight of the item to be carried.  Is the load weight of the object evenly distributed throughout the load?
    • Obtain assistance to lift unbalanced, awkward or heavy items.
    • Check your line of travel.  Is the route you intend to take free from obstacles and tripping hazards?

     

    LIFT USING THE 5 STAGES METHOD

    1. Stand close to the load – spread your feet.
    2. Bend your knees – keep your back straight.
    3. Grasp the load firmly.
    4. Lift smoothly and evenly with your legs taking the strain.  It is important not to twist your trunk or to jerk or shove your body.
    5. Hold the load close to your body.

    Remember     Lift the load from floor to knee, then knee to carrying position and always keep    your back straight.

                            DO NOT ALLOW THE LOAD TO OBSTUCT YOUR VIEW!

    COSHH

     “COSHH” stands for the Control of Substances Hazardous to Health. The aim of these controls is to protect employees from harmful substances, e.g. wood-dust from sanding machines, fumes from solvent adhesives, etc.

    Generic COSHH Assessments have been produced and are held on site. Chemicals which are purchased locally should have been assessed by the line manager purchasing the product with the assistance from the Safety Officer as necessary.

    The risks to staff that follow the manufacturer’s instructions and safe systems of work are normally low.  However, failing to wear PPE, or using PPE that has not been adequately maintained, could put you and your colleagues at risk.  Similarly a product used in an unsafe condition or manner could be harmful.

    Therefore, to ensure you are not put at risk when using chemicals or equipment whilst at work, follow these procedures:

    • Before starting work, read the label and follow the manufacturer’s instructions, e.g. wearing gloves and goggles when using descalers and degreasants.
    • Ensure ventilation/fresh air is adequate when applying adhesives and solvents.
    • Ensure that the correct PPE is available.  Stores should be able to provide all suitable equipment and clothing to you.
    • Check that the PPE is available to use before you start the job.
    • Ensure that local exhaust ventilation systems are working properly and that they are regularly maintained, e.g. ventilation from wood-working machinery, etc. A record should be kept of all maintenance work undertaken.
    • PPE should be regularly checked and, if necessary, replaced.  Filters should be replaced as recommended by the manufacturer, and more frequently if heavily used. A PPE “log” should be kept, detailing who the PPE is issued to, recording maintenance and filter replacements.
    • Follow the safe system of work when using hazardous items.
    • Do not eat or drink whilst handling hazardous items.
    • Report any defects or faults to equipment and plant.
    • Do not transfer hazardous items into unlabeled containers, e.g. decanting acid into small lemonade bottle, etc.
    • Know what safety precautions to take when handling substances you deal with frequently.  Be aware of what to do should an emergency arise, e.g. splashing solvent into your eyes or onto clothing (emergency instructions are normally incorporated into the label of the product).
    • If you are not sure that a substance you have been asked to use has been adequately assessed, speak to your line manager.  Should you require assistance or advice on how to use a product in a dangerous area (e.g. a confined space) call the ESH Team for advice.
    • If you feel ill or drowsy whilst using a product or carrying out a particular task stop immediately and speak to your manager for advice.  Move to an area of fresh air and if necessary obtain treatment from the First Aider.  Do not allow anyone to return to where you were working – or to continue your work in another area – if you have become ill as a direct result of carrying out a particular job.  Ensure that your manager investigates.
    • As well as protecting yourself, consider the possible effects of the use of chemical products and substances on other people who may be indirectly exposed.

    Manual Handling

    We lift, manoeuvre and handle goods every day of our lives in one way or another, not just whilst at work but also during social activities such as gardening.

    A bad back or injury today, could, and regularly does, turn into a painful back problem for life!

    Lifting incorrectly could also lead to a hernia, sprains, strains and even fractures.  Therefore, before lifting items take a few seconds to think – it could save a lot of pain!

    Lifting safely

    • Can a trolley or mechanical lifting aid be used to lift the item instead of handling the item manually?
    • Be kitted-up for the job and, if practicable, obtain firm – grip gloves.  The gloves will also offer protection against cuts, punctures and friction burns.
    • Wear safety shoes to ensure a good floor – surface grip to prevent slipping whilst manoeuvring. The shoes will also provide protection from falling objects.
    • Before lifting assess the weight of the item to be carried.  Is the load weight of the object evenly distributed throughout the load?
    • Obtain assistance to lift unbalanced, awkward or heavy items.
    • Check your line of travel.  Is the route you intend to take free from obstacles and tripping hazards?

    LIFT USING THE 5 STAGES METHOD

    1. Stand close to the load – spread your feet.
    2. Bend your knees – keep your back straight.
    3. Grasp the load firmly.
    4. Lift smoothly and evenly with your legs taking the strain.  It is important not to twist your trunk or to jerk or shove your body.
    5. Hold the load close to your body.

    Remember     Lift the load from floor to knee, then knee to carrying position and always keep    your back straight.

                            DO NOT ALLOW THE LOAD TO OBSTUCT YOUR VIEW!

    COSHH

     “COSHH” stands for the Control of Substances Hazardous to Health. The aim of these controls is to protect employees from harmful substances, e.g. wood-dust from sanding machines, fumes from solvent adhesives, etc.

    Generic COSHH Assessments have been produced and are held on site. Chemicals which are purchased locally should have been assessed by the line manager purchasing the product with the assistance from the Safety Officer as necessary.

    The risks to staff that follow the manufacturer’s instructions and safe systems of work are normally low.  However, failing to wear PPE, or using PPE that has not been adequately maintained, could put you and your colleagues at risk.  Similarly a product used in an unsafe condition or manner could be harmful.

    Therefore, to ensure you are not put at risk when using chemicals or equipment whilst at work, follow these procedures:

    • Before starting work, read the label and follow the manufacturer’s instructions, e.g. wearing gloves and goggles when using descalers and degreasants.
    • Ensure ventilation/fresh air is adequate when applying adhesives and solvents.
    • Ensure that the correct PPE is available.  Stores should be able to provide all suitable equipment and clothing to you.
    • Check that the PPE is available to use before you start the job.
    • Ensure that local exhaust ventilation systems are working properly and that they are regularly maintained, e.g. ventilation from wood-working machinery, etc. A record should be kept of all maintenance work undertaken.
    • PPE should be regularly checked and, if necessary, replaced.  Filters should be replaced as recommended by the manufacturer, and more frequently if heavily used. A PPE “log” should be kept, detailing who the PPE is issued to, recording maintenance and filter replacements.
    • Follow the safe system of work when using hazardous items.
    • Do not eat or drink whilst handling hazardous items.
    • Report any defects or faults to equipment and plant.
    • Do not transfer hazardous items into unlabeled containers, e.g. decanting acid into small lemonade bottle, etc.
    • Know what safety precautions to take when handling substances you deal with frequently.  Be aware of what to do should an emergency arise, e.g. splashing solvent into your eyes or onto clothing (emergency instructions are normally incorporated into the label of the product).
    • If you are not sure that a substance you have been asked to use has been adequately assessed, speak to your line manager.  Should you require assistance or advice on how to use a product in a dangerous area (e.g. a confined space) call the ESH Team for advice?
    • If you feel ill or drowsy whilst using a product or carrying out a particular task stop immediately and speak to your manager for advice.  Move to an area of fresh air and if necessary obtain treatment from the First Aider.  Do not allow anyone to return to where you were working – or to continue your work in another area – if you have become ill as a direct result of carrying out a particular job.  Ensure that your manager investigates.
    • As well as protecting yourself, consider the possible effects of the use of chemical products and substances on other people who may be indirectly exposed.

    Before work commences:

    • Ensure a permit to excavate is provided by competent person.  Determine methods of excavating, installing and removing support work.
    • Provide an adequate supply of material for support work, barriers (and correct traffic notices where appropriate).  If road works signs are needed they need to be erected by street works supervisor.
    • Determine positions of all public services and ensure that they are adequately marked, and/or disconnected using such information as provided by drawings, cable locating equipment, ground boxes etc.
    • For the purposes of excavations, no ground should be considered “good” or “safe” until it has been investigated by a competent person.
    • Check whether excavation will affect adjoining roads or buildings.
    • Always seek advice before excavating below existing foundations.  It may be necessary to provide shoring, i.e. raking or flying shores or both.
    • Prevent access – especially of children.
    • Provide adequate and sufficient ladders and ropes for securing access and egress.

    Checks during Operations:

    • Ensure sound material is being used for support work.
    • Ensure that approved and safe methods are adopted for the installation of support work in excavations.  A competent person should be in attendance at all times.
    • Ensure that all working surfaces are safe.
    • Install timbering as soon as excavation sides are trimmed.  This should be done from ground level or from inside existing timbering.  Do not enter an unsupported excavation unless authorised to do so by a competent person.
    • Ensure that all support work is secure and that props and wedges are tight and properly maintained.
    • Check for signs of over-stress in support work, damage from plant and, when timber is used, make long term check for disease/defects i.e. dry rot, shakes etc.
    • Check for water or soil seeping through support work.
    • Check for signs of earth peeling/cracking at unsupported faces.
    • Check that there are adequate ladders, that they are maintained, secured and used correctly.
    • When pumping, ensure that there are adequate pumps and that soil is not being drawn from behind support work.
    • Monitor for unhealthy atmospheres which may include gas monitoring/lack of oxygen.
    • Ensure that spoil heaps and materials etc. are kept back 1 metre from the edges of the excavation.
    • Ensure that there are adequate barriers/notices/warning lights.
    • The edges of excavations should be provided with guard rails, hand rails and toe boards. Bridges and gangways should be provided with hand-rails and toe boards.
    • Ensure that “stops” for dumpers, tipping lorries etc are well anchored.
    • Ensure that all passing traffic is kept back from edge of excavation.
    • Ensure correct method of withdrawing support work is issued; if unsafe to strike – leave in.
    • Ensure that machine operators have the best possible vision of work in progress.
    • Ensure that services are marked and protected and adequately supported when exposed in excavations.
    • Carry out inspections daily, prior to each shift, after use of explosives or after inclement weather, particularly frost and rain.
    • Ensure that a record of all examinations is properly recorded in the appropriate form, and signed by a competent person.

    Noise

    Being exposed to noise in excess of 85dB (A) can damage the sense of hearing in some people.  85dB (A) is roughly the level of noise where you have to shout in order to be heard when a person is only one metre away from you.  A jet engine taking off at a distance of 25 metres from you is likely to produce a noise level in excess of 140dB (A).

    Noise assessment of areas needs to be carried out to ensure that where hearing protection is needed then it is identified.  Where practical, action to silence noisy equipment should have also been undertaken.  Areas where silencing is not possible will have been designated Hearing Protection Areas and suitably signed at practical locations.

    Nobody in their right mind would set upon a path of deliberately trying to damage their hearing.  However, being regularly exposed to heavy noise levels – without taking safety precautions – could result in occupational deafness.

    Occupational deafness develops slowly at first – an individual may have difficulty hearing conversation to start with, then Tinnitus (a constant ringing in the ears) develops.  The last stages, perhaps before total deafness, would need the sufferer to wear a hearing aid.

    As we use our sense of hearing for pleasure – to enjoy music, watch films or television and to communicate effectively – as well as to pick up danger signals (such as fat moving cars, sirens, etc.) it is well worth looking after your hearing.

    You can protect your hearing by ensuring you adhere to the following points:

    • Wearing ear defenders where noise levels of 85dB (A) is exceeded.  These areas should normally be signed.  If you have trouble being understood or understanding a conversation at a distance of one metre then it is likely that the noise level is above 85dB (A).
    • Ear defenders should not be worn if they are cracked or damaged in any way.  Check your ear defenders for damage prior to use from the manufacturer’s guide which should be followed for any maintenance required.
    • Ensure that headband of the ear defenders are not slack and that the ear muffs fit properly.
    • Report damaged and noisy plant equipment for repair.
    • Be aware of the risk attached to working in a noisy environment.  Excessive noise can cause stress, lead to accidents and also damage hearing.
    • Immediately consult your doctor if you suffer any problem with your hearing and inform your supervisor.

    Checks during Operations:

    • Ensure sound material is being used for support work.
    • Ensure that approved and safe methods are adopted for the installation of support work in excavations.  A competent person should be in attendance at all times.
    • Ensure that all working surfaces are safe.
    • Install timbering as soon as excavation sides are trimmed.  This should be done from ground level or from inside existing timbering.  Do not enter an unsupported excavation unless authorised to do so by a competent person.
    • Ensure that all support work is secure and that props and wedges are tight and properly maintained.
    • Check for signs of over-stress in support work, damage from plant and, when timber is used, make long term check for disease/defects i.e. dry rot, shakes etc.
    • Check for water or soil seeping through support work.
    • Check for signs of earth peeling/cracking at unsupported faces.
    • Check that there are adequate ladders, that they are maintained, secured and used correctly.
    • When pumping, ensure that there are adequate pumps and that soil is not being drawn from behind support work.
    • Monitor for unhealthy atmospheres which may include gas monitoring/lack of oxygen.
    • Ensure that spoil heaps and materials etc. are kept back 1 metre from the edges of the excavation.
    • Ensure that there are adequate barriers/notices/warning lights.
    • The edges of excavations should be provided with guard rails, hand rails and toe boards. Bridges and gangways should be provided with hand-rails and toe boards.
    • Ensure that “stops” for dumpers, tipping lorries etc are well anchored.
    • Ensure that all passing traffic is kept back from edge of excavation.
    • Ensure correct method of withdrawing support work is issued; if unsafe to strike – leave in.
    • Ensure that machine operators have the best possible vision of work in progress.
    • Ensure that services are marked and protected and adequately supported when exposed in excavations.
    • Carry out inspections daily, prior to each shift, after use of explosives or after inclement weather, particularly frost and rain.
    • Ensure that a record of all examinations is properly recorded in the appropriate form, and signed by a competent person.

    Noise

    Being exposed to noise in excess of 85dB (A) can damage the sense of hearing in some people.  85dB (A) is roughly the level of noise where you have to shout in order to be heard when a person is only one metre away from you.  A jet engine taking off at a distance of 25 metres from you is likely to produce a noise level in excess of 140dB (A).

    Noise assessment of areas needs to be carried out to ensure that where hearing protection is needed then it is identified.  Where practical, action to silence noisy equipment should have also been undertaken.  Areas where silencing is not possible will have been designated Hearing Protection Areas and suitably signed at practical locations.

    Nobody in their right mind would set upon a path of deliberately trying to damage their hearing.  However, being regularly exposed to heavy noise levels – without taking safety precautions – could result in occupational deafness.

    Occupational deafness develops slowly at first – an individual may have difficulty hearing conversation to start with, then Tinnitus (a constant ringing in the ears) develops.  The last stages, perhaps before total deafness, would need the sufferer to wear a hearing aid.

    As we use our sense of hearing for pleasure – to enjoy music, watch films or television and to communicate effectively – as well as to pick up danger signals (such as fat moving cars, sirens, etc.) it is well worth looking after your hearing.

    You can protect your hearing by ensuring you adhere to the following points:

    • Wearing ear defenders where noise levels of 85dB (A) is exceeded.  These areas should normally be signed.  If you have trouble being understood or understanding a conversation at a distance of one metre then it is likely that the noise level is above 85dB (A).
    • Ear defenders should not be worn if they are cracked or damaged in any way.  Check your ear defenders for damage prior to use from the manufacturer’s guide which should be followed for any maintenance required.
    • Ensure that headband of the ear defenders are not slack and that the ear muffs fit properly.
    • Report damaged and noisy plant equipment for repair.
    • Be aware of the risk attached to working in a noisy environment.  Excessive noise can cause stress, lead to accidents and also damage hearing.
    • Immediately consult your doctor if you suffer any problem with your hearing and inform your supervisor.
