5 Description of the ProjectGreenline Underground, a Joint Venture between PORR, Saudi BinLadin Group (SBG) and HBK Contracting Co. W.L.L. have been contracted by Qatar Rail to construct the Green Line of the Doha Metro System. This will include all civil and architectural work including the tunnels, station structures and underground ancillary structures. It will also include provision of the first stage track bed, auxiliary utility systems, emergency and maintenance access and egress as well as mechanical, electric and plumbing service’s and fire suppression systems.

The Green Line will connect the North-west of Doha with the City Centre with 19km of tunnel between Education City and Mushaireb. It is planned that 6 Tunnel Boring Machines (TBM’s) will be used for the underground tunnel boring part of the project and as many as 22 TBM’s across the whole metro project. It is planned that all tunnels will be completed by 31 Aug 2016 and that all stations will be completed by 31 Mar 2018


The JV has been contracted to build six underground stations at the following locations

1. Al Rayyan C-Ring Station2. Al Rayan Sports Roundabout Station3. Al Rayyan Al Messila Station4. Al Rayyan Al Qadeem Station5. Education City South East Station6. Qatar National Library Station

In addition to the stations, there will be other above and below ground structures, including, switchboxes, crossing boxes and emergency exits. There will also be construction of an MLPA and Labour Camp at the end of the Green Line where manufacturing and storage of materials including the concrete tunnel rings. As well as housing most of the labour used on the project, there will be areas within the MLPA West site that will be used for temporary storage and treatment of excavated spoil.

5.1 Access to SiteAccess to site will be kept clear at all times.

Emergency and assembly points will be clearly marked and signed and emergency lighting will be provided to emergency routes below ground in tunnels and other areas without natural light.

The site, has specific Site Layout Plans showing as a minimum:

Access routes into and around the sites

Location of crossing box (Evacuation Shaft-2)

Site facilities such as offices, storage areas, first aid rooms etc.

Emergency assembly points and parking areas for emergency services vehicles

Copies of the Site Layout Drawings are shown in Appendix A of this plan. In addition to copies being included within this plan copies will be displayed on each site.


6 Objectives of the EPRP

The objectives of the EPRP are to:

To maintain a high level of preparedness

To protect emergency responders, personnel and the community from harm

Prevent escalation of the emergency and minimise the consequences

Ensure assistance is provided as quickly as possible to those persons affected by any incident or emergency

Effectively manage and control any emergency

Support emergency services with information, knowledge, skills and equipment

Provide relevant emergency training so that a high level of emergency preparedness can be constantly maintained

Ensure that vital information is communicated to relevant stakeholders as soon as possible

Preservation of information and support any investigation

Facilitate the efficient restoration so that normal operations can be resumed


7 Planning

7.1 Levels of Emergencies The severity of emergencies will vary in scale and different categories and levels of incidents may occur; some may be managed directly by the site team with no attendance from the emergency services, whilst other more serious emergencies may need the full support of external services and other agencies.

To determine the level of response expected, the following tiered approach has been adopted across the Qatar Integrated Rail Project including Greenline.

7.1.1 Level 1 Minor incidents, that causes no serious physical threat to people, property or the environment.

May cause short term disruption (<1 hour) to operations but poses no regulatory or reputational threat.

Typical examples of incidents at this level include:

First aid cases

Minor Medical treatment

Minor property damage

Minor pollution

This level of incident will be dealt with by the immediate site team, generally without the need from other emergency responders within the organization or the emergency services

7.1.2 Level 2Significant incidents, that poses a dangerous threat to people, property or the environment.

May cause medium term disruption to operations (>1hour <24 hours) and may pose a regulatory or reputational threat.


Significant or major injuries as defined by QCS 2010/2014

Localised fire that can be extinguished by persons and equipment at the site

Localised collapse of excavations or structures within the boundary of construction sites

Medium pollution incidents

This level of incident can be dealt with by the immediate site team and emergency response teams and may need the support of the project management team and potentially the emergency services.

7.1.3 Level 3Serious incidents that poses a high likelihood of actual or significant harm to people, property or the environment and has the potential to escalate quickly.


Likely to cause long term disruption to operations (>24 hours) and is likely to pose a regulatory and/or reputational threat.


Fatalities or multiple fatalities either of site personnel and/or members of the public

Collapse of structures outside the boundary of the construction sites

Collapse, overturning or rescue from tower cranes

Fire and or explosions with the potential to spread quickly and will be difficulty to extinguish

Major disruptions to the infrastructure network or essential services such as damage to power, water, gas or communications

Major pollution incidents such as serious contamination of water sources

This level of incident cannot be fully dealt with by the immediate site team or emergency responders. It will need the support of the project management team and the emergency services and/or other external agencies.

7.2 Hazard Identification and Controls The achievement of good health and safety performance and the avoidance of any adverse events stem from effective hazard identification and control of risks.

The process is not a one-off exercise but is a continuous process that starts at the planning and design stage and continues through to the conclusion of the construction stage of the project.

A structured approach to hazard identification and control of risks is through a comprehensive risk assessment that includes the following:

Identify what can go wrong (potential emergencies)

Identify potential hazards (fire, explosion, pollution, etc.)

Identify and implement suitable controls (equipment, procedures, training, etc.).

The identification of hazards is a dynamic process in order to take into account fast changing environments and will be subject to a formal review. As a minimum a formal review will be undertaken:

After any emergency to include any lessons learnt

Every 6 months

Where deemed necessary due to change of circumstances

Risk assessments have been carried out for the construction phase of the works and have identified the types of potential emergencies along with the controls necessary to mitigate the risk of these occurring.

Copies of the risk assessments are shown at Appendix B.

7.3 Types of Emergencies The risk assessments identified the following types of potential emergencies that may be encountered during the construction phase of the works:

Structural collapse of imminent collapse of tunnels and/or adjacent structures/buildings


Fire or smoke in tunnel, stations, buildings, offices and accommodation units

Explosion (compressed gases, fuels etc)

Tunnel flooding from internal or external sources

Accidental or intentional release of hazardous substances or materials

Loss of power inside tunnels and station facilities immobilising trains, loss of lighting and other equipment

Collision or derailment involving construction or private vehicles

Collapse or overturning of lifting equipment

Rescue from tower cranes due to ill health

Rescue and entry into the hyperbaric atmosphere

Accidents and incidents resulting in fatalities or serious injuries (falls from height, struck by falling object, trapping or entanglement with plant or machinery)

Contamination of tunnels or enclosed spaces due to ingress of pollutants/gases

Major disruptions to the infrastructure network or essential services such as damage to power, water, gas or communications

Natural disasters such as flooding, high winds and extreme of temperatures

Major pollution incidents

Security issues including serious vandalism, civil unrest and criminal acts including terrorism

7.4 Emergency Response Procedures Emergencies by definition are often sudden, critical, and usually unexpected, events.

To engender a cohesive and consistent approach in responding to emergencies a set of Emergency Response Procedures covering the types of emergencies envisaged are included within this plan at Appendix C.

Raising the Alarm. Adequate arrangements will be made for raising the alarm and calling the emergency services in the event of an incident underground. It will be borne in mind that a fire at the surface level could endanger those working underground or on open surface. The nature and operation of the emergency alarm system will be related to the scale, layout and nature of the works, and to the nature and extent of known fire and other underground hazards. The fire alarm system will be extended and modified as the tunnelling work proceeds.

The alarm will be clearly perceptible to all persons in the workings, and to key personnel above ground and can include any or all of the following, as appropriate:

Voice warnings

Telephone communications

Hand-operated or electrically operated bells or sirens

Special flashing lights

Flashing of the main lighting circuits


The locations of the alarm devices will take into account the layout of the working area, the adverse nature of the working conditions (especially high noise levels) and the transient nature of the working locations.

All personnel will be given the following set of instructions to follow on the spot when there is an incident underground including a fire or suspicion of fire in the tunnels or underground workings.

Actions

Raise the alarm in the tunnel or on open surface and attack the fire only if it is safe to do so.

Report the incident, stating the following:

nature of the incident, e.g. fire, injury, illness, collapse, atmospheric contamination;

where the incident is;

what assistance is required;

whether evacuation is in progress;

any other relevant information e.g. surface evacuation required.

Action on receiving the alarm

The person on site receiving the alarm should immediately undertake the following actions.

Summon the relevant emergency service, giving a precise assembly point, and arrange for a responsible person to meet them on arrival.

Inform the senior site manager or emergency coordinator.

Evacuation of personnel

In the event of an emergency all personnel will be evacuated to the Emergency Assembly Points as marked on the plans at Appendix 1 using Managers, Fire Marshals and Safety staff.

Accounting for personnel

An access/egress Security card system is being introduced which will list all site personnel in an emergency. The system will accurately indicate the number and location of persons above or below ground at all times. This information will be supplied to the emergency services in the event of an underground fire or other emergency. The system will be supervised and monitored, and all persons using the system will be instructed in its correct use.In the interim period until the security card system is in place, a Tally hut will be set up at the excavation entrance / exit point at the East End. Each individual on site will have their own personal laminated photo id card – which they will hand in to the tally man upon entering the excavation. When received the Tally man will issue the employee with a number. The tally man will hang the id card on the board against where the number came. In the event of an incident, the Tally man will gather up all id cards / numbers and proceed to the assembly point, where he will give the cards and numbers to the engineer in charge – who can then perform an accurate head count of who was in the excavation and check if they got out. Any unaccounted for personnel can be quickly identified and the rescue authorities notified.

Mathew Zachariah Site Engineer Site Controller 3387 1089

The main site controller should:-

a. Ensure that the emergency services and key personnel have been summoned and the emergency plan is activated.

b. Direct the shutting down and evacuation of any areas likely to be affected, in consultation with the incident controller and other key personnel, and control traffic movements within the works.

c. Ensure that personnel are accounted for and that casualties receive medical attention.d. Continually review and assess developments to predict the likely course of events, including the effects

on areas outside the works.e. Liaise with emergency services and with HSE Department.f. Arrange for a log of the emergency to be kept.

2. The incident controller should:-

a. If necessary, carry out duties (a) and (b) above until the main site controller arrivesb. Direct operations at the scene of the incident, i.e.

(i) Rescue and firefighting, until the fire brigade arrives(ii) Searching for casualties(iii) Evacuation of employees to assembly areas

c. Set up communications with the emergency control centred. Advise and inform the emergency servicese. Brief the main site controller.


9 Communications In the event of an emergency situation arising, in the first instance, the individual discovering the emergency should call the appropriate emergency service giving the following details:

a. Their name, title and employer.b. The nature of the emergency.c. The location of the emergency.d. What type of emergency services are required.e. Any other information that may assist the emergency service.

The employee reporting the emergency should ask for confirmation that the emergency services are en route before notifying the internal command chain as detailed in individual site plans.

9.1.1 Equipment

The following communication equipment is being provided:

DECT Telephony and Personal Safety System

The DECT (Digital Enhanced Cordless Telecommunications) System enables through the mobile devices it´s carriers to:

Communicate via Voice (Dialing possible on certain handsets, Messenger will have a pre- defined number saved)

Give Alarm with the integrated Alarm Button Give Alarm with the man- down alerting system (if the device remains in horizontal position for some

time an automatic alert will be triggered)

Furthermore the system will be used for tracking purposes, as all devices will be logged in to the nearest base station and therefore the whereabouts of the device and it´s carrier can be located. As the base stations will be deployed in a distance of maximum 250m the location can be narrowed down to this range.

The advantages of the system are the following:

The communication device is always with the carrier. Automatic text messages can be sent to single persons and groups. In case of any emergency the carrier can immediately press the alarm button without searching for the

nearest emergency call station. An automatic alert function due to the man down functionality of the handsets is given.


Emergency Call Stations

Every 250m additional emergency call stations will be deployed. This stations are hardwired and connected to the IP telephony system. The call stations have 2 buttons, wherein each button will be pre- programmed with a number which will be automatically dialed after pressing the call button.

CCTV System

At each entrance of a tunnel a CCTV camera will be installed. The camera will be high resolution (1080P) with integrated IR illumination to provide pictures even in complete darkness. The cameras will be recorded and permanently shown in the site security managers office. Workers allowed to enter the tunnel will have a different color of their helmets, so that it is easy for the operator to identify any violation (unpermitted access). Furthermore this can be checked in necessary cases together with the

DECT system as well (someone entering, but no DECT device can be tracked). The CCTV system will help to deter unauthorized staff from entering the tunnel. At the entrances signs will be deployed

making everyone aware of the fact that the entrances are monitored and the CCTV streams are recorded. The recording will give the possibility to have footage of any violation and will be used as a supporting document (e.g. print out) in case a violation occurs and a report or withdraw of the site permit (access card) needs to be done.

10.2 Emergency EquipmentThe following emergency equipment will be used on the project:

Personal protective equipment. Good health and safety performance is achieved by the effective identification and control of hazards and risks, but risk elimination can only go so far, and residual risks should be controlled. Reliance on personal protective equipment will be regarded as a last resort. However, in tunnel construction works, some personal protective equipment will be used. Compatibility between items and user acceptance should also be considered.

Head protection and High Visibility Tops. All persons on site will normally wear protective headgear conforming to BS EN 397 at all times. High Visibility Tops to be worn at all times.

Foot protection. Boots, with steel sole plates, toe protection and providing ankle support, conforming to BS EN ISO 20344 and BS EN ISO 20345 will be worn at all times.

Hand protection. Gloves conforming to BS EN 388 will be worn where a person is at risk from cuts, abrasions, burns or contact with corrosive or irritant substances. Elbow-length gloves will be worn when grouting or handling corrosive or irritant substances. Barrier creams will be made available and used by site personnel.

Eye protection. Light eye protection conforming to BS EN 166 will be considered as a minimum level of protection. Personnel engaged on sandblasting, shot blasting, pressurized air and water cleaning, spraying concrete, grinding or chipping, metal cutting, burning and welding, grout mixing and placing. They will also be worn where there is a foreseeable risk of injury while breaking, cutting or drilling concrete or stone or similar material, and by persons handling or injecting hazardous liquids under pressure.

Whole-body protection. Everyone underground will wear flame retardant clothing with integral high-visibility strips or panels.

Additional protective clothing. This will be provided and used where appropriate to the risk, for example in excessively wet conditions, when burning or welding, when handling hazardous substances or working in contaminated ground.

Respiratory protection. Where there is a risk of respiratory damage from dusts, ventilation will be employed to extract or dilute any hazardous materials. The use of respiratory protective equipment, for example dust masks or airstream helmets, will be employed as a last resort. For work in high levels of contamination, for example where chemical protection is required, expert advice will be obtained and followed.

Rescue facilities. Rescue equipment, including full breathing apparatus, will be provided and maintained so that it is readily available in an emergency. All rescue equipment will be stored in containers designed to provide protection from adverse conditions likely to be encountered in the workings.

Self-rescuers. All persons underground will have immediate access to a self-rescuer which provides the user with a supply of oxygen for at least 20 min while walking. Where such oxygen supplies are likely to be needed for longer periods, stockpiles of additional rescuers will be provided at intervals, e.g. in long tunnels. Self-rescuers will normally be worn by persons underground on a belt, but may be stored in racks that are immediately accessible for use in an emergency. Where alternative escape routes are available, racks of self-rescuers will be provided for each escape route. If self-rescuers are


stored on racks, there will be a maintenance and inspection system to check that a sufficient number are always available and that they are always in full working order. Smoke hoods incorporating a built-in oxygen supply, such as from a chemical oxygen-generating cartridge, are quick to don and might be provided as self-rescuers. They can be too large to wear on the belt but will be made immediately available for use in an emergency. As they can be of less than 20 min duration, they will be supplemented by stockpiles of additional self-rescuers as necessary. Oxygen self-rescuers are designed to be used in normobaric conditions only but can be used at up to 1 bar pressure provided the risks from hyperbaric oxygen breathing are addressed. A prototype hyperbaric self-rescuer has been developed for use up to 3.5 bar. Open circuit air-breathing apparatus can be used in hyperbaric conditions but its duration will be significantly reduced. The highest standard of cleanliness will be maintained in situations where oxygen is used. Specialist advice will be sought on how this is best achieved.

First aid provision and procedures. Persons trained in first aid and capable of responding rapidly to any incident will be available at all times on each shift and at all working locations. Advance planning and coordination with CDD will be required if the tunnel is in a particularly inaccessible location. All persons will be informed of the first aid arrangements. All employers will train their on-site supervisory personnel in managing emergencies involving first aid. All personnel will be told that, in the event of serious injury, a casualty will be moved only by a trained first-aider, unless there is the immediate risk of further injury.

Good communications will be put in place between the working areas and the surface facilities. A clear plan of action will be formulated to speed up the transfer of any injured persons from working areas and to ensure that ambulances can reach shaft tops or other access points quickly. Lifting arrangements in shafts will take this into account. Clear instructions will be given to all persons on the for evacuating tunnels in an emergency and for ensuring that injured persons are not left behind or unaccounted for.

First aid facilities. First aid boxes will be provided. They will be made of suitable material (e.g. metal or plastic), and will be designed to protect the contents as far as possible from damp and dirt. They will be clearly identified: the recommended marking is a white cross on a green background. Boxes will be readily accessible to working areas and will be in the charge of designated first-aiders on each shift. Appropriate eye wash facilities will also be provided.

First aid training. First-aiders will be specifically trained to deal with the range and location of incidents likely to occur in tunnelling operations including maintenance and fit-out.

Stretchers. Stretchers (complete with blankets) suitable for the confined space of a tunnel will be provided and maintained. They will be readily accessible for use in working areas in an emergency, and will be protected against dirt and damp. In particular, where access to a tunnel is by a shaft, stretchers should, where practicable, be stored at tunnel level. Appropriate means of safely transporting an injured person to the surface will be provided.

Ambulances. The local ambulance service will be notified of the location of the site and the nature of the work to be carried out. All employees will be made aware of the procedure for calling an ambulance.

Fire-fighting equipment. Water is the principal resource for controlling a fire in compressed-air workings. It will be noted that a fire apparently extinguished can brighten and re-ignite in compressed air. The site of any fire will therefore be cooled and wetted with water and, where it is safe to do so, kept under continuous observation until it is determined that the emergency is over. Normally pressurized fire extinguishers cannot be relied upon to function effectively in elevated ambient air pressure, unless they have been specifically proved to be adequate for the actual conditions. It will be checked with the supplier that the extinguisher is suitable for use in a hyperbaric atmosphere.


Breathing apparatus. Breathing apparatus for use in smoke and fumes will be employed only by those trained in its use. Only self-contained compressed-air breathing apparatus (of a type that does not have an air cushion seal to the mask) will be used. Manufacturers will be consulted concerning the duration of sets at the working pressure in the chamber. The suitability of self-rescuers for working at enhanced pressures and their duration will be verified. Pure oxygen will not be breathed at a partial pressure greater than 2 bar.

Special training. Contingency planning on site will include an analysis of the types of fire possible in the workings and the person’s best placed to tackle the fire. Training (both theoretical and practical) will be given to selected fire-fighters who will then have periodic rehearsals. These persons have a key role in fire incidents and will be trained to issue instructions and to clear non-essential personnel from the workings. The fire service, HSE and local accident-and-emergency hospitals will be informed of the use of compressed air and will be invited to participate in contingency planning. As a general rule, the fire service will not undertake operations in compressed air. A clear understanding of the services that can and will be provided in the event of a fire will be reached.

Safety and Rescue Plan For each project Herrenknecht develops a safety and rescue plan (during project phase), showing escape routes, warning, safety, monitoring, and communication systems. Upon customer request, additional components can be added to this safety and rescue concept. (Herrenknecht Document - EPB SHIELD TBM and Back-Up Concept Datasheet DS4049b00 dated 24/10/2013.


Schematic of an escape and rescue plan

The TBM’s safety installation comprises several components:

o Hand held extinguisher at suitable location

o Smoke / fire detectors at suitable location

o Emergency plunger buttons at suitable location

o Water curtain at the end of the back-up

o Emergency stop switches on TBM and TBM back-up

o Manually operated fire suppression system comprising low density foam or powder sprinklers over high risk areas such as hydraulic power packs and reservoirs.

o Inert gas suppression system to electrical cabinets

o TBM communication system

o Emergency generator

o Refuge container (optional)

o Gas detection systems

Fire Fighting System Different types of fire need to be considered when selecting and arranging the extinguishers. CO2 extinguishers are installed near electrical switchboards, generators, and similar, in order to fight electrical fires. Dry powder fire extinguishers are installed around the control cabin, the air lock, as well as at the beginning and end of every trailer, in order to safeguard emergency exit from the TBM. This will be provided by Herrenknecht as per EPB SHIELD TBM and Back-Up Concept Datasheet DS4049b00 dated 24/10/2013 .

11 Training, Exercises and Drills

11.1 Training

It is a requirement for all persons at work to be given appropriate information on and training in health and safety related to the risks they might encounter at work. Special training requirements apply in certain circumstances, for example first-aid, plant operation, and, for work in compressed air. In addition to basic site inductions, specific induction training will always be given before any person starts work underground, whether as a new employee or as a person new to the project. Persons who are new to the industry are particularly vulnerable, and their induction training and the degree of supervision of their work will reflect this. Specific induction training will cover:

information on possible hazards, risks and health effects; the devised safe methods of working to address the hazards and risks; site rules imposed by the principal contractor and prohibited activities; the provision, use and care of protective equipment; site communications and procedures; those with particular responsibilities for health and safety; actions in the event of any emergency, particularly raising the alarm, places of safety

underground and egress from underground workplaces.

Toolbox talks are established as a valuable method of on-the-job-training at the workplace and for imparting and updating health and safety knowledge. Such talks will be held frequently. They will cover method statements for new or major work activity, reinforce knowledge about ongoing activities and draw attention to near misses or incidents which have occurred. They will be fairly brief and restricted to essentials, but allow for feedback and questions from those present. The talks will also take place whenever circumstances in the workplace change significantly or when new hazards are anticipated or become evident. Visitors to underground projects will be given appropriate induction training. They will be accompanied by an experienced member of the project staff. All underground personnel will be trained in the care and use of fire-fighting equipment. All site personnel will be made familiar with the site emergency procedures prescribed. Emergency drills including evacuation will be held at regular intervals to familiarize all personnel with the practical working of the systems. Site Induction. All CDD staff will have a Group HSSE Induction centrally and individual

site specific inductions.

H&S Tunnel Training. All tunnel staff will have the following H&S training:

H₂S / BA 1 day Confined Space Awareness 1 day Emergency First Aid at Work 1 day (to include stretchers) all staff Advanced First Aid 3 days - 1:4 ratio Basic Fire Fighting

TBM Familiarization and training.


Air Lock Attendant. Compressed Air Works.

11.2 Exercises and DrillsExercises and drills are to be held in order to practice for emergencies and to assess the effectiveness of this Plan and to identify lessons learnt.

Examples of outlined emergency scenarios for both below and above ground are as follows (these will be expanded and used for emergency exercises and drills):

A fire has occurred on a vehicle which was being used to transport visitors to the tunnel face. The visitors were being shown the TBM at the tunnel face and the vehicle was left between the tunnel face and the entrance when a fire started in the vehicle. It is unlikely that all personnel will be able to evacuate from the tunnel in a safe manner due to the reduced visibility and the smoke in the tunnel.

During a tunnelling operation, water ingress through a lining joint has released Hydrogen Sulphide (H2S) due to the reduced ambient air pressure within the tunnel. This has caused the H2S detectors worn on 2 of the crew’s ankles to alarm however, the H2S detector on the TBM is not registering any alarm.

An underground worker has been trapped and seriously injured by an inadvertent operation of the machine erector arm. The individual is unconscious but is breathing, however he is losing blood from injuries to both his legs.

An electrical circuit has malfunctioned within the Tunnel Boring Machine and as a result a fire has caught hold within the length of the machine. The fire alarm system has detected the fire in the TBM.

An underground worker has witnessed an inundation of water from one of the cross passage sites. It appears that the water flow is increasing at steady rate and is already starting to flow into the tunnel.

An individual underground worker has become trapped in a shaft when the gears on a hoist have failed, the individual has called for assistance and the TC has been notified.

A number of workers are working within the TBM when a power failure occurs. The power appears to be off throughout the tunnel system.

An underground worker assigned to check a disused shaft, finds what appears to be a member of the public unconscious at the bottom of the shaft. He also hears voices of other individuals somewhere in the tunnel who do not reply when he calls them.

Emergency exercises and drills will be held as a minimum:

At least every 6 months for offices

At least every 3 months for sites

At least monthly for underground works

Emergency drills and exercises will be held with the emergency services to ensure a coordinated approach and engender mutual cooperation and ensure there is effective control of all emergencies.


A record of all exercises and drills will be maintained.

11.3 Emergency Escalation Chart


12 Records

12.1 Log of EventsA Log of Events will be maintained by the Incident Commander to record all actions taken and communications received or issued. The Log of Events will be utilised during the Post Event Review.

12.2 Post Event ReviewThe organisation shall undertake a full review after an emergency incident occurs or after any exercise or drill and produce a Post Event Report.

The main aim of this review and report is to identify any lesson learnt such as what went well or not so well and where improvements can be made to improve the overall effectiveness and management of the emergency arrangements.

Any improvements/lessons learnt will be incorporate into this EPRP and shared amongst all responders.

A copy of the Post Event Report will be issued to Qatar Rail within 7 days of the emergency.


13 Audit and Review

13.1 AuditTo ensure that suitable management arrangements are being implemented and maintained formal audits of this EPRP and the emergency arrangements will be undertaken.

Audits will occur at least:

Annually

As otherwise directed by Qatar Rail

13.2 ReviewThe organisation shall ensure that this EPRP is reviewed regularly and updated as necessary to ensure it remains relevant and effective.

The following instances will trigger a review:

After every monthly emergency evacuation drill
