Introduction

This presentation provides some of the safety aspects duringthe Decommissioning and Disposal (D&D) of Long TermStorage Facility in Mukim Belanja, Perak, Malaysia

With a great support from subcontractors, project personnel,vendors, suppliers, regulatory agencies, and others, theproject has achieved a significant safety record without anymajor incident or accident


3/29

Background

Decommissioning and Disposal (D&D) of the Long TermStorage Facility (LTSF) project in Perak, Malaysia.

The LTSF-D&D project commenced in early 2010 and expectedto complete by end 2014


4/29

LTSF

The LTSF contained over 87,000 drums of low level NaturallyOccurring Radioactive Materials (NORM) waste residues thatwere generated from the processing of monazite andxenotime ores


5/29

Main Activity

The LTSF-D&D project involved: the removal and processing of the LTSF contents, demolition of the LTSF structure, and

dispose of these materials into a disposal facility,Engineered Cell 2 (EC 2).


6/29

Early Stage

During 2010 and the first half of 2011, work at the Siteconsisted of general construction activities included;

earthworks,

building construction, electrical construction, and installation of plant and equipment.


7/29

Actual D&D Work

The actual D&D work wascommenced in the middle of 2011and was completed end of 2013

Involved drums retrieval, processingand waste placement activities

Semi-automated mechanical androbotic equipment were employedto ease the D&D activity


8/29

Workforce

The workforce in Malaysia is multi-ethnic and the first majorchallenge on the project was to manage communication toworkers originating from multi-national backgroundsincluding;

the United States, the United Kingdom, Australia,

Indonesia, India, Bangladesh, Pakistan, and Nepal


9/29

Strategy

Developed a safety culture on theproject

Promoted a behavior-based safetyprogram

Sharing safety and health information Management support necessary to

make safe decisions

Training program Safety promotion such as quizzes and

best safety award Established Work Permit system


10/29

Enforcement Agency

Conventional construction safety under the jurisdiction of theMalaysian Department of Occupational Safety and Health(DOSH); and

Radiation protection under the jurisdiction of the MalaysianAtomic Energy Licensing Board (AELB).


11/29


12/29

Collaboration with Agency

Review of Safety Plan and Radiation Protection Plan Safety training, site briefing and regular safety updates Site inspection and monitoring

Emergency drill exercise


13/29

Monitoring

Plant and equipment inspected andendorsed by DOSH

Monitoring and supervision by AELB

Regular safety site walk by projectsafety and health, and radiation

protection personnel


14/29

Safety Committee

A Project Occupational Health and Safety Committee (POSHC)was established

Met every month chaired by Project Manager Member of POSCH consisted:

Safety and Health Officer (Secretary) Radiation Protection Officer (RPO) Management Representatives Worker Representatives Supervisors

Radiation Protection Action Group (RPAG) was anothercommittee that was established to manage radiation issues

chaired by the RPO


15/29

Safety Committee (continue)

POSHC and RPAG discussed issuesassociated with occupational safetyand radiation protection included:

safety performance andstatistics,

monitoring data and dosereporting,

training program, housekeeping and personal

hygiene, ALARA observation and safety promotion and campaign.


16/29

Registration

The construction site and theinstalled plant were registered withDOSH under OSHA 1994 and FMA1967

All workers were trained andregistered as a Construction Workerunder CIDB Act 520

Workers handling radioactive wastematerials were trained andregistered as a Radiation Workerunder Act 304

Workerbriefing


23/29

Radiation Work Permit

An administrative tool used to control work occurring insidethe radiation work zones

Specify knownradioactivity

levels in workplace

If supplemental

dosimeterrequired

What minimum

PPE is needed

Whatmonitoring

required

Workers awareof specific

hazards


24/29

Radiation Work Zones


25/29

Personal Protective Equipment

PPE provided to all workers onproject

Critical for protection fromradioactive contamination

Workers were trained for the correctuse and maintain of their PPE

Respiratory protection implemented


26/29

Safety Achievement

The project achieved over 3 million man-hours without a lost-time-injury (LTI)


27/29

Safety Achievement

The same team on the Plant D&D and LTSF-D&D projectsachieved over 4.5 million man-hours without an LTI


28/29

Safety Achievement

The Project was successfully completed without any significantradiation exposure to workers (the dose results below theregulatory limit of 20 mSv/year)
