Introduction
Further to an invitation from Mr. Grant Hood
(WDHB – Whanganui District Health Board.)
AISL - Asbestos Inspection Services Limited was requested to carry out a
Management Survey at -
Taihape Hospital, Ambulance Bay.
There are 2 designated categories of Asbestos surveys currently available.
These are listed below:
Management Survey
Standard sampling, identification and assessment survey (Sampling Survey),
the purpose of which is to locate as far as reasonably Practicable the presence
and extent of any suspect asbestos containing materials in the building and
their condition. This is done by the collection and analysis of samples of
suspect asbestos containing materials.
Refurbishment / Demolition Survey
Full access sampling and identification survey (Pre-demolition/Major
Refurbishment Survey). This type of survey is used to locate and describe as far
as reasonably practicable, all asbestos containing materials in the building and
may involve destructive inspection as necessary to gain access to all areas,
including those that may be difficult to reach. A full sampling programme is
undertaken to identify possible asbestos containing materials and estimates of
the volume and surface areas of asbestos containing materials made.
Access arrangements were made with aid of Mr. Grant Hood (Whanganui District
Health Board) to ensure all accessible areas were surveyed during the project.
The survey was carried out on 16/03/2018 and completed 10 days thereafter.
The survey was to include for visual inspection within the above premises.
The survey was undertaken and completed by members of the AISL – Asbestos
Inspection Services Limited survey team.
During the survey the building remained un-occupied.
5
Disclaimer
Every effort has been made to identify all asbestos materials so far as was
reasonably practicable to do so within the scope of the survey and
the attached report. Methods used to carry out the survey were agreed with the
client prior to any works being commenced.
Survey techniques used involves trained and experienced surveyors using the
combined approach about visual examination. and bulk sample collections
where required.
It is always possible after a survey that asbestos based materials may remain
in the property or area covered by that survey, this could be due to several
reasons:
•
Asbestos materials existing outside the scope of the survey.
•
Materials may be concealed or hidden by other items or covered surfaces
i.e. paint, over boarding, concealing etc. Where this is the case then
its discovery will be limited.
•
Asbestos may well be hidden as part of the structure to a building and
not visible until the structure is demolished later.
•
Fragments from previous asbestos removal projects may well be
present in various areas; general asbestos fragments do not form
part of this survey however all good intentions are made for its
discovery.
Where an area has been formerly stripped of asbestos i.e. plant rooms,
ducts etc. and new coverings added, it must be pointed out that
asbestos removal techniques have improved steadily over the years since its
initial introduction. Most particularly would be the Health and Safety at Work
(Asbestos) Regulations 2016, that outline enforceable strategies. Asbestos
removal prior to this regulation would not be of today’s standard and
therefore fragments may be present beneath new coverings.
This survey will detail areas accessed and all samples taken, where an area is not
covered by this survey it will be due to No Access for one reason or other i.e.
working technicians, delicate location or just simply no admittance. It may have
been necessary for the restrictions of the surveyor’s specialist to
be confirmed prior to the survey.
Admittance for the survey may be restricted for many reasons outside our
control such as height, deadlines to others, steady complications
or confined space. Where electrical equipment is present and presumed in the
way of the survey no access will be attempted until proof of its safe state is
given. Our operatives have a duty of care under the Health and Safety at Work
Act (2016) for both themselves and others.
6
Disclaimer
In the structure where asbestos has been located and not all zones have been
examined, any material that is found to be suspicious and not detailed as part of
the survey should be treated with caution and sampled accordingly.
Certain materials contain asbestos to variable grades and some may be
less densely contaminated at certain locations (Artex for example). Where this is
the case the sample taken may not be representative of the whole
product throughout, therefore composite sampling is therefore encouraged.
Where a survey is carried out under the guidance of the owner of the property or
his representative, then the survey will be as per his/her instructions and
supervision at that time.
Asbestos Inspection Services Limited cannot accept any liability for loss,
injury, damage or penalty issues due to errors or oversights contained within
this report.
Asbestos Inspection Services Limited cannot be held responsible for any
damage caused as part of this survey carried out on your behalf. Due to the
landscape and stipulation of sampling for asbestos some danger is inevitable
and will be limited to just that necessary for the taking of the sample.

General Recommendations for Asbestos Cement Products.
Work with cement products containing asbestos is covered by the Management and
Removal of Asbestos (November 2016) Approved Code of Practice.
An assessment of all proposed works which may disturb any asbestos should be
carried out to launch the risk existing, the appropriate precautions must be adopted
to control any exposure. This should combine the succeeding over-all principles:
•
Where work on asbestos cement is inevitable, keep the materials wet
during work and avoid breakage wherever possible. Acceptable PPE
must be worn always.
•
Avoid using power tools. If deemed necessary to use power tools set at the
lowest possible speed, exhaust ventilation such as cowls must be fitted to
power tool and utilising the “investigation technique” with high efficiency H
type vacuum units.
•
Organise the work in a single controlled location where practicable, to
streamline control and supervision. Isolate working areas using warning
signs and tape barriers, or in case of significant fibre levels by means of a
sealed polythene work enclosure and negative pressure equipment. Air
tests must also be carried out by an independent asbestos assessor.
•
Signify respirator zones where the Control Limit is likely to be exceeded
and ensure that all persons entering the zones wear appropriate RPE/PPE
are trained in its use.
•
Ensure that those persons employed in working on asbestos cement are
suitably trained in the correct working practices, control methods and
anticipation of risks.
•
Keep the work area clean during the work and use methods that abate dust
creation, avoid sweeping and brushing, which will make dust airborne.
•
Dispose of asbestos cement waste safely as Asbestos Waste under the
statutory consignment note procedures in accordance with the Health
and Safety at Work (Asbestos) Regulations 2016.
•
Avoid further disturbance of asbestos cement products wherever possible
by relocating or re-routing facilities.
•
Clearly identify and label any asbestos cement products.

General Recommendations for Asbestos Insulation,
Coatings or Insulating Board (AIB)
Where the materials are in safe condition and the risk of disturbance is small, they
can be maintained on site. They should be identified with adequate warning signs
and routinely inspected for damages. All asbestos materials should not be drilled,
abraded or disturbed in any way.
All asbestos containing materials should be removed prior to any planned
refurbishment or demolition works, where damage is likely to be sustained during
the occupant’s activities or where future decline is likely.
Work on any of these items may only be carried out by a specialist contractor
licensed under the Health & Safety at Work Act 2016. The selected contractor is
required to notify the WSNZ at least 5 days prior to commencement of the works,
and to provide a written Method Statement as follows:
•
Full explanation of the works to be carried out and its duration.
•
Type, quantity and location of asbestos to be removed.
•
Anticipated exposure levels and persons affected.
•
Enclosure construction details, layout and location, signage and
ventilation.
•
Protections to be adopted to minimize exposure to lowest possible level
and to control release of asbestos fibre beyond the work area.
•
Validation for any withdrawal from preferred methods, e.g. where wet
stripping cannot be used.
•
Type, use and decontamination of RPE/PPE
•
Waste removal and disposal procedures
•
Training and instruction of employees
•
Emergency procedures on site

Material Assessment Methods
total risk score of between 0 and 12 is calculated using four categories
that are evaluated by the surveyor against given values. The criteria
and the respective values are as follows:
Product Type
1
Asbestos reinforced composites such as plastics, resins, mastic,
roofing felt, vinyl tiles, paints and decorative finishes, asbestos
cement products.
2
Asbestos insulation board, mill boards, other low-density insulation
boards, asbestos textiles, gaskets, ropes and woven textiles,
asbestos paper and felt.
3
Thermal insulation (e.g. pipe and boiler lagging), sprayed asbestos,
loose asbestos, asbestos mattresses and packing.
Condition/Extent of Damage
0
Good condition, no visible damage.
1
Low damage, a few scratches or surface marks, broken edges on
boards, tiles etc.
2
Medium damage, significant breakage of materials or several small
areas where material has been damaged, revealing loose asbestos
fibres.
3
High damage or delamination of materials, sprays and thermal
insulation. Visible asbestos debris.
Surface Treatment
0
Composite materials containing asbestos, such as reinforced
plastics, resins, vinyl tiles.
1
Enclosed sprays and lagging, asbestos insulation board with exposed
surface painted or encapsulated, asbestos cement products.
2
Unsealed asbestos insulation board or encapsulated lagging and
sprays.
3
Unsealed lagging and sprays.
11
Material Assessment Methods
Asbestos Type
1
Chrysotile (white) asbestos.
2
Amosite (brown) asbestos.
3
Crocidolite (blue) asbestos.
The algorithms shown against each situation are added together to give a total material
risk score, for conciseness, the register we have prepared contains only the total risk
score rather than the component scores.
The total score for each situation can be broadly classified using the following bands:
Material Risk Score
0 - 3 Very Low Risk
4 - 6 Low Risk
7 – 9 Medium Risk
10 – 12 High Risk
It is likely that high risk items will be highlighted in the report text and that some
immediate action will be required.
Other items may also be measured for consideration where the decision of the
surveyor recommends this would be beneficial.
12
Priority Assessment Formula
A priority risk score of between 0 and 12 is calculated using four categories that
are evaluated by the duty holder.
Although a surveyor may have some of the information which will contribute to
the risk assessment and may be part of an assessment team, the duty holder is
required to make a risk assessment based on the survey findings and their
detailed knowledge of the activities carried out within the premises. The criteria
and the respective values are as follows:
