2:  Introduction
Wairarapa District Health Board (WrDHB) as a person conducting a business or undertaking (PCBU) in
accordance with the Health and Safety at Work Act 2015  has a primary  duty of  care to ensure the
health  and safety  of  workers  as  far as reasonably practicable.  As  a PCBU,  WrDHB  is committed to
ensuring that  patients,  members of  the public,  employees and contractor workers do not become
inadvertently exposed to asbestos fibres.
This Asbestos Management Plan sets out how WrDHB's identified asbestos and asbestos containing
material (ACM) will be managed in accordance with legislative requirements under the Health and
Safety at Work Act 2015 (HSWA), Health and Safety at Work (Asbestos) Regulations 2016 and
approved codes of Practice
The following key areas will be covered in this plan:
Act
•
Identification of asbestos and ACM
•
Informing workers where they may find asbestos/ACM
• Decisions on how asbestos risks are managed and the reasoning behind these decisions
•
Information about the workers carrying out work involving asbestos
Information
- roles and responsibilities
- information and training that has or will be provided
- health monitoring that has or will be conducted
Official
•  Procedures for removal of asbestos in the workplace
the
•  Procedures for incidents or emergencies involving asbestos in the workplace
•  Processes for review of this Asbestos Management Plan
•  Procedures for selection and approval
under  of approved Asbestos Management Contractors
This plan should be read in conjunction with the Health and Safety at Work (Asbestos) Regulations
2016 and WrDHB's Asbestos Management Policy.
Released
3:  Regulatory Requirements
The Health and Safety at Work (Asbestos) Regulations 2016 requires PCBU's to ensure the following:
so far as is reasonably practicable, that all asbestos or ACM giving rise to a risk at the
workplace is identified;
the presence and location of asbestos or ACM identified at the workplace are clearly
indicated;
the Asbestos Management Plan for the workplace is prepared and that the information in
the Asbestos Management Plan is kept up to date;
that the plan is reviewed and revised
WrDHB Asbestos Management Plan August 2018

4: Asbestos Background
Asbestos is the name used to describe naturally occurring silicate minerals, which form in fibrous
strands. The natural strength, fire and chemical resistance properties of asbestos made it a highly
popular product for use in building materials from the 1940s until the late 1980s. Buildings built or
refurbished in this timeframe are likely to contain asbestos and/or ACM.
The potential health effects of asbestos include asbestosis, lung cancer and mesothelioma in the
worst cases.  The latency between exposure to ACM and development/diagnosis of diseases means
that it is imperative those workers in direct contact with asbestos are monitored on a regular and
ongoing basis.
It is important to understand that if asbestos or ACM is in good condition and left undisturbed, the
likelihood of fibres being released into the air is very low.  In these instances, it is often safer to
regularly review the condition of the asbestos/ ACM and leave the material in situ.
Asbestos is generally separated into two categories,  non-friable and friable. These terms are applied
to the condition of the asbestos or ACM prior to work being undertaken. The categories
Act are a
reflection of the level of risk associated with a given piece or area of asbestos/ ACM.  Friable is the
highest risk condition for asbestos/ACM, whilst non-friable is usually safer unless abraded or
disturbed.
Information
Friable asbestos/ACM
Friable asbestos/ ACM is able to be crumbled pulverised or crushed into powder by hand pressure
when it is dry. Asbestos/ACM in powder form also falls into this category.
Official
Non-friable asbestos/ACM
Non-friable asbestos/ACM is by definition, not friable. Asbestos fibres are generally bonded into the
the
product and those fibres will only be released should manipulation or machining occur.
under
5: Wairarapa DHB Asbestos Management Plan
This Asbestos Management Plan is to be read in conjunction with the WrDHB Asbestos Register. As
PCBU,  WrDHB will make this  Plan and the Asbestos  Register readily available via WrDHB's Intranet,

asbestos .  Additional information such as the plan and the register is available on request.
Information
7: Asbestos/ ACM  Identification
Official
ACM has been identified since the 1980s as a potential health hazard. To establish the risk posed by
the
asbestos, possible uses, locations and condition of asbestos must be known. To gather this
information, annual inspections are undertaken across WrDHB sites.
under
For any new lease or purchase of buildings there will be surveys completed to identify the actual or
likely presence of asbestos.  Results of these surveys will be added to the Asbestos Register.
8: Asbestos Surveys
Released
Surveys undertaken on behalf of WrDHB will be carried out by a Licenced Asbestos Assessor and will
be undertaken in accordance with WorkSafe NZ's Good Practice Guidelines for Conducting Asbestos
Surveys {2016).  Any samples required as part of identification will be sealed and clearly labelled as
potential asbestos/ ACM and sent only to an IANZ accredited laboratory.
The purpose of the annual surveys is to locate as far as reasonably practicable, the presence and
location of any identified or assumed asbestos/ ACM in a building which could potentially give rise to
a risk of exposure to airborne asbestos fibres. An example of this is ACM that could be damaged or
disturbed during normal occupancy or foreseeable maintenance and installation work.  As part of the
survey, the risk assessment of the asbestos  (Appendix 2) identifies the best option for management
of the asbestos.
Asbestos surveys and due diligence are also undertaken on all leased buildings to ensure any
asbestos is identified and adequately managed.
WrDHB Asbestos Management Plan August 2018
7

These surveys are completed annually where required, or at the time of new lease or purchase of
buildings.
9: Wairarapa DHB Asbestos Register
WrDHB Asbestos Register contains records of asbestos surveys, including locations, sample analysis
results and identified and assumed asbestos or ACM. The Asbestos Register is intended to provide a
starting point for project managers, trades, maintenance workers and others to assist in the
identification and effective management of asbestos across all WrDHB sites.  Clearance inspections
and certifications are also held within the Asbestos  Register.
WrDHB requires project managers, maintenance workers and contractors to review the Asbestos
Register prior to commencement of work within any building where asbestos or ACM has been
identified or likely to be present. Where positive results are indicated via laboratory testing an
asbestos risk assessment is required to be undertaken for the proposed works prior to
commencement.
Act
Asbestos locations and assessments will be added to the WrDHB  Risk Register.
The Asbestos Register and other associated documentation have been assigned a traffic light colour
coding system based on the risk of asbestos present.
Information
Red indicates presence of asbestos, high risk
n0e indicates presence of asbestos, medium risk
Green indicates no asbestos identified

History
Released
WrDHB current building and infrastructure assets are a mixture of new hospital build {2006) and
retained buildings of the Masterton Hospital Campus following subdivision of the original land. The
older buildings reflect the standard of the time of construction and associated refurbishment.
In the decades preceding the development of this Asbestos Management Plan, several buildings
containing asbestos/ACM were reported to have been stripped of any asbestos/ACM that was
found.
Recent asbestos surveys identified scattered remnants of this asbestos/ ACM resulting in
contamination of building subfloor areas.
WrDHB Asbestos Management Plan August 2018
8

Condition monitoring of identified asbestos
An independent monitoring programme by external consultants ensures that identified
asbestos/ ACM is not at risk of deteriorating and releasing fibres.  Risk assessments are conducted
during surveys and monitoring of asbestos.
Removal of asbestos/ACM in sound and good condition may not be immediately necessary as the
risk to occupants and the community may be deemed negligible.  Risk assessments undertaken
during the surveying and monitoring process identify the best option for management of the
asbestos/ ACM.
Identifying the presence of asbestos/ ACM and documenting the ongoing condition of asbestos is a
continual process and recorded in the Asbestos Register. When asbestos/ ACM has been identified as
damaged or deteriorating, condition-monitoring frequency can be either increased or the current
management option will be reviewed based on a risk assessment.
Act
Asbestos Labelling
All work conducted on asbestos/ ACM will be undertaken in a manner to ensure that health risks are
minimised.
All asbestos/ACM that has not been removed will be progressively labelled where practicable. The
details regarding a location are recorded within the WrDHB Asbestos Register.
Information
Communication of the labelling and what labels mean will be included in induction material of all
Workers and will be available in accessible area for visitors to sites.
Official
Any labelled asbestos/ ACM will not be disturbed by any person until the proposed action has been
identified and risk assessed.
the
under
11: Asbestos Removal Works
All asbestos removal works undertaken on behalf of Wr0HB must be in accordance with Health and
Safety at Work Act (Asbestos)  Regulations 2016 and the Approved Code of Practice for the
Management and Removal of Asbestos 2016.
Released
Procedure for Asbestos Removal
1. Building &  Property Services will select a licensed asbestos removalist.  The selection must
follow the guidelines as set out under the regulations to ensure a trained, certified and
experienced company/person is engaged.
2. An Asbestos Removal Control Plan is a document that identifies the specific control
measures the licensed asbestos removalist will use to make sure workers and other people
are not put at risk when carrying out the work.
3. The licensed asbestos removal contractor must provide a copy of the Asbestos Removal
Control Plan as part of a Site Specific Safety Plan to the responsible person for review and
approval prior to the start of any asbestos removal works

4. All contractors must have completed an induction prior to undertaking any work.
5. Notification of asbestos removal
•
Notification to WorkSafe
Before undertaking any asbestos removal work at WrDHB sites the asbestos removal
contractor must notify WorkSafe NZ in writing at least 5 days before licensed removal
work. The contractor is to inform WorkSafe via their website, using the Notification of
Licensed Asbestos Removal form in accordance with regulation 34.
In the case where  immediate removal  is required, the licensed asbestos removalist must
give notice to WorkSafe immediately by telephone and in writing within  24  hours of
notice given by telephone.
•
Notification to workers and other occupants
WrDHB will ensure that the following person(s) are informed, where appropriate,  that
asbestos removal work is to be carried out at the workplace and when the work is to
commence,  prior to the work commencing:
Act
•
Executive Leader Operations

under
WrDHB will refuse entry to anyone who does not comply with a control measure
implemented for the workplace regarding asbestos or who does not comply with the
direction of a licensed asbestos removalist.
Released
7. Clearance inspections and certificates
WrDHB will engage an independent licensed asbestos assessor to undertake clearance
inspections upon the completion of asbestos removal works. The clearance inspection,  for
Class A removal works is a four stage process:
•
Stage 1- Preliminary check of site condition and job completion
•
Stage 2 - Thorough visual inspection of work area
•
Stage 3 - Air monitoring and swab samples (where applicable)
•
Stage 4 - Final assessment post work in area of  asbestos removal
Class B removal works comprise of Stage 1 and 4.  Upon successful completion of the
clearance inspection, the independent assessor will issue a clearance certificate verifying
that the area is safe to re-occupy. This document also certifies that the safe removal of
asbestos within the area  specified and in  accordance  with the Asbestos  Removal Control
Plan, has been completed.
WrDHB  Asbestos  Management Plan August 2018
10

Should any staff have concerns about reoccupying an area where asbestos removal works
has been undertaken, a copy of this document is provided for their reassurance.  Clearance
Certificates will be available on request from Building & Property Services.
8. Background air monitoring
WrDHB will engage an independent licensed assessor to undertake integrity testing of
containment areas where required under Asbestos Regulations, prior to works beginning.
The independent assesor will also be engaged where required under Asbestos Regulations,
to undertake background air monitoring during the removal and provide results as necessary
to assure the health and safety of individuals within the vicinity of the removal works.
9. Updating the Asbestos Register
Upon the completion of asbestos removal works the Building & Property Services Manager
will update the Asbestos Register with the relevant documentation and actions taken.
Asbestos that was not removed will be labelled.  This information will also be shared with
the Health and Safety Manager to update the Risk Register if required.Act
12:  Incidents,  Emergencies and Health  Monitoring
Discovery of Unknown Suspected Asbestos
WrDHB has developed a standalone document, which is provided to contractors and maintenance
staff outlining the procedure should unknown asbestos be discovered or suspected.
Information
The procedure is
included as part of this document as Appendix 1 and forms part of tender documentation and/or as
part of contract/work scoping.
Official
Incident Response
the
In the event of a high-risk incident, such as ceiling tile collapse, earthquake or storm damage extra
precautions will be taken to minimise the spread of asbestos fibres from the damaged ACM. The
under
potential release of asbestos fibres within a building or building exterior may necessitate the
isolation and/or evacuation of an area.
Where ACMs have been damaged or damaged materials/suspected deterioration are identified
during inspection or following an event, the emergency procedure below is to be followed:
Released
•
No person(s) should attempt to clean up potential asbestos containing materials
•
Isolate the area where possible by closing doors, windows and turning off extraction fans
etc. and contact Building & Property Services

test(s) and arranging and managing any remedial works required
•
Maintain controlled access to the area until such time as formal clearance has been
confirmed;  and
maintain frequent communication with staff and all other relevant parties, providing
updates as necessary to ensure the access arrangements are not breached
Health  Monitoring
WrDHB has a requirement to monitor the health of workers who are known to have been exposed
to asbestos.
Workers exposed to asbestos will be reported to the Occupational Health Service to arrange
monitoring.
Act
Periodic follow-up to detect any changes in the function of the workers lungs will occur.  Asbestos
related disease takes many years to develop so records must be kept for at least 40 years.
Workers who leave the employment of WrDHB will have their records and details added to the
Worksafe  National  Asbestos register.  It needs to be noted that the register is not used to prompt
