Introduction to company’s aims and objectives
As the Health & Safety Manager for the crane company. I’m here by required to do a detailed
report for the Dutch Health and Safety authority listing all the sequential steps taken by
following the accident.
This document will provide a detailed Risk Assessment and Method Statement explaining how
our company is going to remove cranes from the water and buildings with minimum impact to
all local shops and residence. Main objective of this report is to analyse specific construction
related safety problems and identify the key issues to be addressed in the solution of such
problems.
Alphen aan den Rijn on the 3rd of August 2015
Accident summary report
20 people were injured in the town of Alphen aan den Rijn after two cranes lifting a bridge
section toppled on to three houses, clothing store and art and drawing supplies store. The cranes
that were working from barges, were renovating the Queen Juliana Bridge, the two tower
cranes on a barge began to shift and toppled over on to a row of houses, slamming through the
buildings and sending a cloud of dust. Following images will show technical drawings of the
barges and cranes before the accident.

8. C123 Alphen ann den rijn crane salvage 8
Scope of works
Site investigation - walk the site, check if qualifications of operatives are valid and
appropriate to the works to be carried out on site’ and obtain all necessary permits and
establish traffic management plan.
Divert pedestrian traffic via a temporary pedestrian crossing to the west, east and north.
Site setup – Erect traffic barriers, fencing, signage, get required plant and equipment
to site and establish welfare and storage facilities.
Establish Crane positions for the removal by means of anchors points, best structural
stability and ordering of the Main boom of 700 tons Terex AC700 lifted onto pontoon.
Barge will be hired to provide a working platform on the water for the duration of the
works for attaching the necessary cables for lifting the crane.
Two telescopic mobile cranes will arrive and be fixed to the fallen cranes first as they
lay on top of the bridge section and will be attached
In order to carry out this operation the existing barge will be used for lowering the
pieces of crane on stable position out of the water.
The crane will then begin the operation of lifting the cranes out by pieces. Starting with
the steam of the fallen cranes and then the vehicle.
Upon completion Structural Engineer will inspect lifting of the bridge section that is
associated with works;
Cranes will be dispatched off site
Bridge section will be lifted and positioned on the built barge structure as before the
accident that will be located where the fallen barges used to sit.
Houses supported by shoring / demolish dangerous buildings.
Make good road and footpath.
All materials and equipment will be removed from site.
Site clean-up and removal of site facilities and fencing and other associated equipment.
Client Inspection/snags.
Handover.
9. C123 Alphen ann den rijn crane salvage 9
Site specific Safety Plan
Site Security
It is proposed to fence off Site area with fencing with crash barriers facing the road this
measure is to provide protect site operatives and members of the public by segregating traffic
from site operations; Details of which will be in our traffic management plan for the project.
In addition, 24 hour site security will be provided for the duration of the project given the
location of the site and its proximity to the river and vehicular traffic in the area. The security
officer will ensure that no unauthorised personnel may enter the work area during the clean-
up and that all visitors to site sign in at the site office at that stage they will be accompanied
to the works area with authorised personnel.
A security hut will be positioned at the main entrance to the site. The security officer’s roles
will include:
Ensuring that only permitted personnel and deliveries are allowed access to the site.
Maintain detailed records of all people entering and leaving the site.
Communicate all site hazards with personnel entering the site and make them aware of
the risks associated with the works in progress.
Security of the site against theft and vandalism.
Ensure adequate lighting and appropriate safety signage is in place.
Ensure that plant and equipment is secured where applicable.
Site rules & emergency procedures
Designated Safe assembly areas will be provided for emergencies. All personnel will be
required to attend site specific induction training prior to working on site.
During the induction training they will be advised on any safety issues and site specific hazards.
10. C123 Alphen ann den rijn crane salvage 10
Welfare facilities & First aid
Welfare facilities will be provided on-site to meet the requirements of HAS authority
Specific items that will be included are:
Potable drinking water;
Porta-loos (given the lack of useable site space);
Canteen/meeting/induction room;
Changing facilities/Drying room.
A designated First Aiders will be appointed to deal with minor accidents on site. If the First
Aider is unable to deal with an injury, the emergency services will be contacted.
Operatives will be made aware of the Site First Aider on site and the location of first aid
equipment which will include a defibrillator in accordance with company policy.
Sit access
It is proposed to liaise with the local authorities when planning deliveries of heavy plant,
equipment or materials to site, this measure is to provide a safe passage for operatives and to
ensure the safety of pedestrians and other road users.
This will entail lane and footpath closures for the duration of the works, Warning signage on
approach to the site entrance, additional lighting after dark and road supervision when required,
during peak periods, to allow safe movement of traffic.
A designated set-down area for staff vehicles will be provided for off lading of tools and
equipment but parking will not be provided given the lack of useable site space.
11. C123 Alphen ann den rijn crane salvage 11
Transport
Hazards associated with traffic and transport will be controlled in the form of liaison with local
authorities.
Other issues that require attention in order to insure a safe passage to site include:
A route survey will be carried out to ensure the safe passage of oversized loads to the
site such as the delivery of the cranes;
To avoid any major disruption, experienced banks persons will be used. These
personnel will exercise proper signalling techniques during the deliveries of large loads
to Site.
Road preparation such as marking realignment will be carried out as required in
accordance with the traffic management plan.
Date & time of deliveries will be check against local events.
Consultation and notification of possible road closure/diversion strategies will be put
in place in advance for delivery of any large loads.
A temporary Pedestrian crossing will be set up to divert pedestrian traffic approaching the site.
Pedestrians will be diverted across the road safety at a temporary level crossing which will be
sign posted accordingly.
Crash barriers and fences will be erected around site to protect members of the public from site
operations and site personnel form vehicular traffic.

13. C123 Alphen ann den rijn crane salvage 13
Required plant and equipment
Mobile welding unit
This will be used when the fallen cranes stem will have to be removed from the main vehicle.
Also if necessary welded on supports will be placed on cranes for to lift them safely. This is
the preferred choice for this site.
Only qualified, competent personnel will operate this machine. A check will be carried out to
determine when it was last tested/serviced and a visual inspection will be caries out to check
for damage or wear on any cabling and to safety devices are working.
Grinder
Electric grinder will be selected as to remove the steam from the fallen crane vehicle. Also if
found necessary the cables that have been stranded under the bridge section will have to be
removed.
Some of the safety devices the grinder must provide are:
Anti kick back;
Restart protection - Prevents the grinder restarting after a power cut;
Anti rotation guard - Prevents the guard moving should a disc shatter;
Vibration control;
Start current limitation or soft start.
14. C123 Alphen ann den rijn crane salvage 14
Life jackets & Harness
These will be worn by all other operatives and visitors on site due to the sites proximity to the
water.
Certification will be checked on all life jackets and on each harness. In addition, the harness
will be checked for grease on the linings and will be inspected routinely for damage and wear
along with the other life jackets.
Barge HEBO P12
Will be hired so that the cranes can be transported off site and for the duration of the works. It
will access the cranes from the north as seen in figure 3. It will allow to have a safe platform
for workers to grind and weld off the crane stem from a stable and adjustable platform when
installing the fixing points, to the fallen crane.
15. C123 Alphen ann den rijn crane salvage 15
Floating buck
The Crane will be hired for the duration of the project. This crane is an excellent choice for this
project as it has slewing capabilities and can travel with a load. This feature offers a lot more
mobility as it will be located on the river which take up a lot of the limited, available site space
that is not being used. Its long span over the barge and the fallen cranes will allow extra reach
and can lift heavy loads of up to 300 tones

16. C123 Alphen ann den rijn crane salvage 16
Telescopic Crane MAMMOET
The Crane three cranes will be a for the duration of works on site that will be located on land.
Their main purphose will be to assist the Barge crane and for the banksman to direct the cranes.
Telescopic craneoffers a lot more mobilityaround the site and has sufficient ground to stand on
thee crane, requires a solid base to operate safely. This is provided by the existing roadway
that, as part of the contract, will be re-surfaced upon completion of the works.
18. C123 Alphen ann den rijn crane salvage 18
What is a Risk assessment?
Risk assessments are an essential tool for the implementation of good health and safety
management. Risk Assessment is where the severity of the Hazard and its potential outcomes
are considered in conjunction with other factors including the level of exposure and the
numbers of persons exposed and the risk of that hazard being realised.
Additionally, all employers regardless of the size of the business are required to carry out a risk
assessment at their place of work and to keep a written record of the risk assessment for each
job for the purpose of possible inspection by the Health and Safety Authority.
Risk Assessment aims
The Aim of a Risk Assessment is to demonstrate the company’s ability to identify hazards in
the workplace or those that are associated with a particular task and in turn assess the risk and
outline the recommended control measures to be adopted. These findings are presented in a
written format, in simple language, in order for them to be fully understood by those who are
going to carry out the task.
‘Risk’ is defined as the likelihood that a person may be harmed or suffers adverse health effects
if exposed to a hazard
What are control Measures
19. C123 Alphen ann den rijn crane salvage 19
The process of risk assessment
In carrying out risk assessments employers must look closely at what or what activities could
cause harm to their employees, visitors and members of the public and in determine the
appropriate control measures to be implemented to reduce or minimise the risk.
Risk Assessment classification
The following table indicates the classification of a ‘Hazard’ and a ‘Risk’.

Introduction
A method statement is a way of documenting the hazards involved in carrying out specific
tasks and in turn communicating the risk and precautions required to all personnel involved.
The statement should not be complicated or longer than necessary to achieve these objectives.
Method Statements are for the benefit of those carrying out the work and their immediate
supervisors therefore they should be clear and written in simple language suited to those
carrying out the operations and should not be over complicated.
Equipment needed for safe working should be identified and made available before work starts.
The Method Statement should be updated as the work proceeds and personnel should be
informed and trained if their required work methods need to be changed.
Permit to work systems (PTWS)
PTW systems set out systematically the works to be carried out, the hazards involved and the
precautionary measures to be employed.
Situations where PTWS are necessary include:
1. Hot works such as Welding and the use of a grinder.
2. Working in confined spaces. Such as Excavations.
3. Crane Operations.
4. Working at heights.
The employer should document in the safety statement what work activities require a permit to
work system and details of which will be noted on the site specific Method Statement.
Employers must also need to consider the associated regulations and codes of practice related
to the task.
The Method Statement for the Salvage crane and bridge section are details of the following:
• The Project (location, duration etc.).
• Personnel Involved.
• The required Key Plant, Tools and Equipment.
• Specific Identified Residual Hazard.
• Specific staff training and details of permits to work.
• Sequence of operations.
• Access, Egress and Traffic management.
• Fall protection procedures.
• Hazardous substances and storage of same.
• PPE First Aid & Hospital Information.

Traffic
Management
As seen in the traffic management plan it is proposed to fence off with crash barriers
employed for the duration of works. Signage will be erected on and around site for the
information of personnel and members of the public. A temporary pedestrian crossing
will divert pedestrians across the road. A construction vehicle staging area will be
located to the east at site vehicle entrance. Vehicles, after being security cleared will
reverse into site and upon completion of delivery/collection will exit via same entrance.
Pedestrian entrance will be to the west beside accommodation area.
Crane Operations of lifting plan
The project supervisor will ensure that all members of the appointed crane team employed to
salvage the section on site are fully aware of their roles and duties, and that each person has
sufficient knowledge, training and experience to carry out their work safely. Records of
training and experience will be verified and their details will be retained in the site safety file.
Lift supervisor will supervise and co-ordinate all lifting activities in accordance with the Lift
Plan. This person will brief all lifting team members i.e., crane operators, slingers and
appointed banks person on each lift. Project supervisor will be responsible for the planning,
risk control measure and safe lifting procedure before they commence the lifting operation.
The Lift supervisor will ensure that a permit is issued by the project manager before he instructs
his team to carry out any lifting operation on site. The Lift supervisor will brief the lift team
members on the Lift Plan before commencement of any lifting operation and can stop the lifting
operation.

Conclusion
The crane and bridge section should go smoothly as all risks have been identified and the
likelihood that a person may be harmed or suffers adverse health effects being eliminated in
this statement.
All employers are required to carry out a risk assessment at the site and to keep a written record
of that risk assessment for each job. The main reasons why risk assessments are carried out are
to prevent financial costs associated, moral/ ethical and the legal reasons.
Carrying out a risk assessment, preparing a method statement and their implementation are
required by law under the Safety, Health and Welfare at Work Act 2005.Risk assessments are
an essential tool for the implementation of good health and safety management. In carrying out
Risk assessments the severity of the Hazard and its potential outcomes are considered in
conjunction with other factors, these include, the level of exposure and the numbers of persons
exposed and the risk of that hazard being realised.
Risk Assessments are to demonstrate the company’s ability to identify hazards in the workplace
or such that are associated with a particular task and, in turn outline the recommended control
measures to be adopted. These findings are presented in a written format, in simple language
appropriate to the persons who are to carry out the task.
After identifying the risk or hazards, employers must adopt control measures to reduce or
remove the potential of an operative’s exposure to a particular Hazard or reduce the likelihood
of the risk of the exposure to that hazard being realised.
28. C123 Alphen ann den rijn crane salvage 28
A method statement is a way of documenting the hazards involved in carrying out specific
tasks and in turn communicating the risks and precautions required to all personnel involved
in the work. The statement should again, not be complicated and be written in simple language
appropriate to the personnel whom are carrying out the tasks.
In line with the Method statement, Equipment needed for safe working should be identified
and made available before work starts. The Method Statement should be updated if necessary,
as the work proceeds and Personnel should be informed if their work methods need.
Permit to work systems are written systems to protect workers in dangerous areas. They set out
systematically the works to be carried out, the hazards involved and the precautionary measures
to be employed.
