Ben Williams – ACR Environmental Consultants Work Orders 1723-5812 & 1723-7643.

High lead in soil found from sampling around Buggy Shed. Due to the findings in the inspection & sampling conducted ACR recommends that the following actions be undertaken;


• Restrict access to the area surrounding the building, to ensure that none of the settled paint flakes on the ground can be transmitted to other areas or buildings. • Advise the surrounding buildings & tenants of the issues & the planned works to remediate the issues. • Dust sampling is to be undertaken from the surfaces inside the building to check for contamination from the works completed. • All walls & areas 2m (or to boundary fence) from the walls are to be sprayed with a PVA based sealant (or similar) using a low-pressure airless sprayer. • Removal of soils that have been found to have a high volume of contaminated materials should be removed to a depth of 200mm minimum.

C100710-28-R01 Bld 28 - Hazardous Materials Survey Register Report 1

1 INTRODUCTION Safe Work and Environments Pty Ltd (SWE) was commissioned by the Australian National University (ANU) Facilities & Services Division to undertake a Hazardous Materials Survey of Building 28 located at the ANU Acton Campus, Acton, ACT. The survey was undertaken by Mr. Kieran Shields (ACT Licenced Asbestos Assessor No. 2014149) on the 5th of December, 2014. The purpose of the survey was to identify hazardous materials within the building, document findings and produce a current hazardous materials register for the site which can be incorporated into the site asbestos materials management plan in compliance with the ACT

Dangerous Substances (General) Regulation (2004).

1.1 Scope of Works

The scope of works involved the following:

Development of a task specific Safe Work Method Statement (SWMS); Walkthrough inspection of the site building/s; Identification of all visible and accessible hazardous materials including asbestos, lead, SMF, PCBs &

ODSs; Sampling of suspect materials where necessary/possible; Laboratory analysis of selected samples where the assessor suspected the presence of asbestos or

lead containing materials; and Preparation of a Hazardous Materials Register with photographs of identified hazardous items and

site plans marked up to show the location of asbestos items.

1.2 Objectives

The objectives of the Hazardous Materials Survey are to:

Identify hazardous materials within the building(s); Detail the survey methodology; Provide a qualitative risk assessment of the identified hazardous materials and provide information

regarding health risks; Provide recommendations for control measures and management strategies; Prepare a document containing including the Hazardous Materials Register for the site to ensure

compliance with regulation and the existing site management plan.

1.3 Background

The site has not been previously assessed by Safe Work and Environments. The purpose of the survey was to comply with current regulations and to identify asbestos containing materials within the building to enable the asbestos containing materials to be managed.

It is a requirement of the ACT Dangerous Substances (General) Regulation (2004) that all non-domestic premises built before December 2003 have in place an Asbestos Management Plan including an Asbestos Materials Register. These plans must be compiled by an ACT appropriately licensed Asbestos Assessor.



1.4 Legislative Requirements

The survey works and production of this report have been undertaken in accordance with the requirements of:

Work Health and Safety Act 2011.

ACT Dangerous Substances Act 2004.

Dangerous Substances (General) Regulation 2004.

Dangerous Substances (General) Amendment Regulation 2007.

2 SURVEY METHODOLOGY Hazardous materials surveys (including asbestos (AS), synthetic mineral fibre (SMF [in friable and exposed condition]), lead based paint systems (Pb), Ozone Depleting Substances (ODS) and Polychlorinated Biphenyls (PCB)) are carried out applying a risk management approach to identify, assess and ultimately control the risk associated with the identified materials. Furthermore semi-quantitative asbestos risk assessment methodology was applied to assess the risk of all identified asbestos situations. This assessment methodology is presented in the below section 3.0 Asbestos Risk Assessment.

The survey comprises a walk through survey of the accessible areas of the premises and may also include the gathering of anecdotal information available from the public space, building occupants, owners and property management where available. Based upon the aforementioned information sources and physical inaccessibility on the day of the assessment, building fabric and fittings suspected of containing any of the above referenced hazardous materials are identified by means of visual observation and representative sampling. Sampling for asbestos and lead based paint systems will be confirmed by laboratory analysis. These findings will then be included in the hazardous materials register (Section 4.0) with all notated items risk assessed as per the above mentioned methodology.

The surveys are typically limited to the experience and training of the surveyor(s) and the information and access made available at the time of the survey by the client. All SWE surveyors are trained in accordance with our in house hazardous materials consulting manual and work instructions for asbestos and hazardous materials surveys, which amongst other parameters requires that all surveyors are trained by and ‘shadowed’ on numerous diverse sites by a competent and experienced surveyor prior to carrying out independent surveys. There is, however, still a possibility that some hazardous (asbestos) materials may not be identified as any surveying is subject to human error.

Where necessary the surveyor will sample suspected hazardous material situations to confirm or refute the presence asbestos fibres or other hazardous item within the sampled materials. All sampling is undertaken by use of representative sampling which caters for numerous similar situations when appropriate. This means that a close inspection of all similar situations within the site is carried out, however, sampling may not be undertaken to reduce the risk of disturbance of materials, exposure to occupants and surveyor and analytical costs for client. Some sampling is also conducted as what is referred to as presumptive sampling. Presumptive samples may be included in the hazardous materials register where no actual sample is collected but there is reason to presume that a hazardous material may be present; however, no access and/or safe access for sampling and/or no visual access can be obtained. Examples of typical presumptive samples are millboard insulation to electrical duct heaters, electrical backing boards, lift brake linings and similar. Sample collection is conducted in a non-destructive and non-invasive manner.

A standard hazardous materials survey does not include access and inspection of any areas that will require special access permits or other means of access to restricted areas such as confined spaces, work at height, isolation of energy services, live equipment and mechanical building services, partial demolition of structures and similar access limitations.

All properties will have concealed materials in its current state that cannot be accessed or revealed prior to demolition or refurbishment of the structure(s). Ongoing assessment of building materials is recommended and required during any such structural work and should be carried out by hazardous materials awareness trained personnel. Where any suspected material is uncovered an experienced hazardous materials consultant should be contacted to sample, risk assess and document the finding(s).



3 HAZARDOUS MATERIALS RISK ASSESMENT 3.1 Asbestos

Asbestos is considered a health risk whenever a potential asbestos fibre release is likely to occur. The health risk posed by asbestos containing materials and products in premises are due to a number of risk factors including:

Condition of the material; Friability of the material; Airborne potential of the material; Accessibility of the material; and Location of the material.

A risk level for asbestos products or materials can be determined by multiplying the hazard level for the given asbestos type* by the 5 variants (above) which have also been assigned hazard levels (Table 1). The risk assessment methodology used in our assessment is based on the Australian Standard AS4360-1999, “Risk Management”.

A qualitative Asbestos materials risk assessment is undertaken each time an asbestos survey or re-survey of the site/property or structures is conducted and detailed in an Asbestos Report Register (ARR). The risk assessments are performed by competent persons only. Each asbestos situation is allocated either a ‘High’, ‘Moderate’, ‘Low’ or ‘Nil’ risk rating (Table 2). These ratings are defined as follows:

High Risk: There is an immediate exposure risk to anyone entering the area due to friable material which has already been disturbed or there is a short term exposure risk to anyone entering the area (usually a friable or poorly bonded material in an average or poor condition). Immediate action is required to restrict access and stop the spread of fibres or dust as well as plan for decontamination and remedial works.

Moderate risk: Due to the material status and/or activity in the area. Usually applies to bonded materials in a state of minor deterioration and in moderate to high activity levels, or accessible friable materials in good condition.

Low Risk: Poses a negligible or low risk to occupants of the area due to the material being in sound condition unless seriously disturbed. Usually applies to bonded or sealed products in at least average condition, or materials with no or low accessibility.

The risk assessment of the asbestos containing material is to be reviewed when:

The Asbestos Management Plan is reviewed; Further asbestos or ACM is identified at the workplace; Asbestos is removed from or disturbed, sealed, enclosed or undergoes any other change in condition; There is evidence that the risk assessment is no longer valid; There is evidence that control methods are not effective; or A significant change is proposed for the workplace or for work practices or procedures relevant to the

risk assessment.

Alternatively an asbestos risk assessment review is to be conducted every 5 years if not effected by one or more of the aforementioned variables. This is to be performed by a competent person.



Table 1: Asbestos risk assessment factors.

0 1 2

No Asbestos Detected (NAD) Non-friable Friable

1 2 3

No sign of damage/deterioration, non-friable Mild damage/deterioration, friable by force Severe damage/deterioration, very friable

Accessibility – Hazard Level 1 to 3

1 2 3

Fully concealed behind a false wall or ceiling, sealed/painted. Inaccessible due to height. Partial encapsulation, low activity area, low exposure to weathering and/or physical impact. No encapsulation, high activity area; exposed to weathering, people and maintenance.

Airborne Potential – Hazard Level 1 to 3 Exposure potential – Hazard Level 1 to 3

1 2 3

Material not present in common air space. Material exposed to natural ventilation Material exposed to forced ventilation (A/C, fans)

1 2 3

Accessed only by maintenance personnel. Accessible to small numbers of personnel. Readily accessible to the majority of persons

By multiplying the hazard level from each risk factor the total can then be used to determine the recommended Health Risk/Action Priority Levels as presented in Table 2.

Table 2: Asbestos risk score, status and action priority categories.

Risk Level Risk Status Action Priority

50+ High (H) Immediate action should be taken (Materials that pose an immediate or elevated health risk to employees and/or general public – assessed as in poor condition / very friable).

20 - 49 Moderate (M) Removal or encapsulation and regular monitoring of the material is recommended (likely potential for further deterioration, instability and an increased risk of exposure).

1 - 19 Low (L) Label, maintain and review (Products or materials that pose little health risk to employees and/or general public – assessed as stable, non-friable, low access)

0 Nil (N) No action necessary

Note: Where any planned maintenance, refurbishment or demolition works will disturb ACM, licensed removal is recommended.

3.2 Synthetic Mineral Fibres

The risk assessment factors for SMF are similar to those of asbestos including:

Evidence of physical damage; Accessibility to material; Likelihood of disturbance; Accessibility to exposed areas; and Environmental and occupational conditions.

High Risk: Friable synthetic mineral fibre exposed and readily accessible.

Moderate Risk: Friable synthetic mineral fibre or damaged bonded material which due to its present condition and/or location is likely to be further damaged resulting in fibre release.

Low Risk: Non-friable or seated stable friable material that is unlikely to present a risk to health unless damaged, tooled, cut, sanded or machined.



3.3 Lead

Lead when inhaled or ingested is toxic to humans. The lead containing paint risk assessment factors are assessed based on these two exposure routes on human receptors (infants, children, adults or contractors). These factors include:

Likelihood of inhalation or ingestion; Likelihood of disturbance; Condition of the paint system; and Environmental and occupational conditions.

High Risk: Damaged or deteriorated paint membrane, which due to its present condition and location, presents a significant health risk.

Moderate Risk: Paint membrane showing signs of deterioration and weathering which if left will continue to deteriorate and require abatement that is more extensive.

Low Risk: Stable paint membrane that is in good condition and/or covered by a lead-free paint membrane, which is also in a good condition.

Lead paint is defined by the Australian Standard (AS 4361.2 – 1998 Guide to lead paint management Part 2:

Residential and Commercial buildings) as a paint or component coat of a paint system containing lead or lead compounds, in which the lead content (calculated as lead metal) is in excess of 1.0% by weight of the dry film as determined by laboratory testing.

3.3.1 Lead-containing dusts

Settled dust containing lead in ceilings spaces, voids and cavities is in fine particles and has a potential for greater bioavailability causing serious long-term health problems on the brain, kidneys and reproductive organs. Human exposure is through inhalation or ingestion. Routes of exposure and risk assessment factors include:

Areas of exposed soil adjacent to the building; Type of materials and age of the building; Refurbishment works conducted on the building; Distance from roads, commercial garages and mining/smelting operations; Dust fall rates and carpet wear; and Nature of paint work.

In the absence of a legislative standard, SWE (in consultation with the Department of Health and WorkCover) has adopted a threshold of 300 mg/kg which is considered appropriate for residential roof / ceiling cavities).

The below lead dust guidelines are extracted from Australian Standards AS 4361.2-1998, Section 5.6.4.2 (Surface Dust Lead Loadings) after lead paint management activities. The permissible amount of leaded dust remaining on each of the following surfaces following lead hazard work is:

1 mg/m2 on floors (carpeted or uncarpeted) 5 mg/m2 on interior window sills (or stools). 8 mg/m2 on window troughs (the area where the sash sits when closed). 8 mg/m2 on exterior concrete.



3.4 Polychlorinated Biphenyls

Polychlorinated biphenyls (PCBs) are a set of persistent organic chemicals that are known or suspected to cause a wide range of health effects. There is clear evidence that PCBs cause cancer in animals, and they are considered probable human carcinogens [U.S. Environmental Protection Agency (EPA) 1996]. Human and animal data provide evidence that PCBs have significant toxic effects, including effects on the immune system, the reproductive system, the nervous system, and the endocrine system.

High Risk: PCB oil leaking from the component item under consideration.

Low Risk: Component item is in good condition. Unlikely to present a risk to health unless capacitor is damaged or deteriorates.

3.5 Ozone Depleting Substances (ODS)

The risk assessment factors for Ozone Depleting Substances (ODS) are similar to those of asbestos including:

Evidence of physical damage; Accessibility to material; Likelihood of disturbance; Leakage; Accessibility to exposed areas; and Environmental and occupational conditions.



4 STATEMENT OF LIMITATIONS This report and the associated services performed by SWE are in accordance with the scope of services set out in the contract between SWE and the Client. The scope of services was defined by the requests of the Client, by the time and budgetary constraints imposed by the Client, and by the availability of access to the Subject Site.

SWE derived the data in this report primarily from research, visual inspections, examination of available records, interviews with individuals with information about the site, and if requested, limited sample collection and analysis made on the dates indicated. In preparing this report, SWE has relied upon, and presumed accurate, certain information provided by government authorities, the Client and others identified herein. Except as otherwise stated in the report, SWE has not attempted to verify the accuracy or completeness of any such information.

Limitations also apply to analytical methods used in the identification of substances [refer to examples a), b) and c) below]. These limitations may be due to non-homogenous material being sampled (i.e. the sample to be analysed may not be representative), low concentrations, the presence of ‘masking’ agents and the restrictions of the approved analytical technique. As such, non-statistically significant sampling results can only be interpreted as ‘indicative’ and not used for quantitative assessments.

a). Due to the very low concentration of asbestos fibres and the non-homogenous matrix of vinyl floor tiles, false negative results may be obtained. Therefore the accuracy of all results cannot be guaranteed.

b). Notably, with some asbestos containing bulk material it can be very difficult, or impossible to detect the presence of asbestos using the polarised light microscopy analytical method, even after ashing or disintegration of samples. This is due to the low grade or small length or diameter of asbestos fibres present in the material, or attributed to the fact that, very fine fibres have been distributed individually throughout the materials.

c). The analysis of many asbestos products used as a component of insulation materials, may be compromised in instances where the material has been heat affected, as heat may alter the morphology of the fibrous material.

No warranty, undertaking, or guarantee, whether expressed or implied, is made with respect to the data reported or to the findings, observation, conclusions and recommendations expressed in this report. Furthermore, such data, findings, observations, conclusions and recommendations are based solely upon the existence at the time of the investigation. The passage of time, manifestation of latent conditions or impacts of future events (e.g. changes in legislation, scientific knowledge, land uses, etc) may require further investigation at the site with subsequent data analysis and re-evaluation of the findings, observation, conclusions and recommendations expressed in this report.

This report has been prepared on behalf of and for the exclusive use of the Client, and is subject to and issued in connection with the provisions of the agreement between SWE and the Client. SWE accepts no liability or responsibility whatsoever and expressly disclaims any responsibility for or in respect of any use of or reliance upon this report by any third party or parties.

Quality Control Definitions

Blank: This is the component of the analytical signal which is not derived from the sample but from reagents, glassware etc, can be determined by processing solvents and reagents in exactly the same manner as for samples. Duplicate : This is the complete duplicate analysis of a sample from the process batch. If possible, the sample selected should be one where the analyte concentration is easily measurable. Matrix Spike : A portion of the sample is spiked with a known concentration of target analyte. The purpose of the matrix spike is to monitor the performance of the analytical method used and to determine whether matrix interferences exist. LCS (Laboratory Control Sample) : This comprises either a standard reference material or a control matrix (such as a blank sand or water) fortified with analytes representative of the analyte class. It is simply a check sample. Surrogate Spike: Surrogates are known additions to each sample, blank, matrix spike and LCS in a batch, of compounds which are similar to the analyte of interest, however are not expected to be found in real samples.

Laboratory Acceptance Criteria

Duplicate sample and matrix spike recoveries may not be reported on smaller jobs, however, were analysed at a frequency to meet or exceed NEPM requirements. All samples are tested in batches of 20. The duplicate sample RPD and matrix spike recoveries for the batch were within the laboratory acceptance criteria. Filters, swabs, wipes, tubes and badges will not have duplicate data as the whole sample is generally extracted during sample extraction. Spikes for Physical and Aggregate Tests are not applicable. For VOCs in water samples, three vials are required for duplicate or spike analysis.

Duplicates: <5xPQL - any RPD is acceptable; >5xPQL - 0-50% RPD is acceptable. Matrix Spikes, LCS and Surrogate recoveries: Generally 70-130% for inorganics/metals; 60-140% for organics and 10-140% for SVOC and speciated phenols is acceptable. In circumstances where no duplicate and/or sample spike has been reported at 1 in 10 and/or 1 in 20 samples respectively, the sample volume submitted was insufficient in order to satisfy laboratory QA/QC protocols. When samples are received where certain analytes are outside of recommended technical holding times (THTs), the analysis has proceeded. Where analytes are on the verge of breaching THTs, every effort will be made to analyse within the THT or as soon as practicable.

Re: RFQ ANU17-004 – ANU Building 28 - Immediate Action Reinspection

Dear Shaun,

Colin Chapman, an ACT Licensed Asbestos Assessor of Robson Environmental Pty Ltd (Robson), conducted a reinspection of Building 28 to confirm the status of the “immediate” action items detailed in Section 3.1.2(b) in Annexure A of the Australian National University (ANU) Request for Quotation (RFQ) ANU17-044 as shown in Figure 1 below.

APPENDIX A: Additional Materials Analysis Report ............................................................ 12

Purpose

The purpose of this reinspection was to satisfy requirements of Section 3.1.2(b) in Annexure A of the ANU Request for Quotation (RFQ) ANU17-044. This was achieved through a building visit and focused examination of the applicable action item(s). If remediation was found to have not yet been completed, recommendations are provided within this report.

Where required, interim measures were put in place during the reinspection by Robson’s ACT Licensed Asbestos Assessor. This was undertaken to mitigate any increased risk to building occupants due to changed condition, accessibility, airborne potential and/or exposure potential of the associated hazardous materials since the last reinspection.

Limitations

While Robson has taken all care and attention to ensure that this report includes the most accurate information available, the reinspection was focused on the immediate action items provided in the ANU Request for Quotation (RFQ) ANU17-044.

Additionally, the reinspection was dependent upon information provided in the applicable electronic reports and registers accessible through the ANU Hazardous Materials Register link (https://services.anu.edu.au/campus-environment/building-management). Access to these electronic references was provided to Robson by Facilities and Services at ANU.

If either of these electronic references contained inaccuracies, it may not have been possible to examine a specific action item. If this was revealed during the reinspection, it is detailed in the Findings & Recommendations section of this report.

https://services.anu.edu.au/campus-environment/building-management


Additional hazardous substances were only identified if they were obvious to the Assessor at the time of the reinspection. As such, this report compliments, but does not supersede, the applicable electronic reports and registers accessible through the ANU Hazardous Materials Register link.

Reinspection Process

Notifications were distributed to relevant personnel by ANU Facilities and Services and the immediate action items reinspection for Building 28 was undertaken on 19 September 2017. Personnel involved included:

Mr. Shaun Oostryck, NSW State Manager, NS Projects. Mr. Benjamin Hooper, Assistant Project Manager, NS Projects. Mr. Brett Morrison, Asset Planning Officer, ANU. Mr. Colin Chapman, Senior HazMat Consultant, Robson.

The published report and associated register accessible through the ANU Hazardous Materials Register link were used to identify the items requiring immediate action. These were authored by Safe Work & Environments Pty Ltd (SWE) and contained information related to the identification, evaluation and determination of actions appropriate to control exposure to hazardous materials including Asbestos, Synthetic Mineral Fibres (SMF), Lead, Lead-Containing Dusts, Polychlorinated Biphenyls (PCBs), Ozone Depleting Substances (ODS) and Fuel Storage Facilities. It was the items identified as requiring immediate action within these documents that Robson examined.

Reinspection Findings and Recommendations

The associated Hazardous Materials Register is accessible through the ANU Hazardous Materials Register link (https://services.anu.edu.au/campus-environment/building-management) and the ANU Request for Quotation (RFQ) ANU17-044 notes that Building 28 has the following:

Has 2 contaminants.

Findings and observations for the immediate action items specific to this building are detailed below and summarised in Table 1.

1. The asbestos cement debris on the ground outside the northeast side of the building was identified as Asbestos Containing Materials (ACM) in the last SWE reinspection. An action to remove the asbestos cement debris ASAP was recommended. Findings during the September 2017 reinspection include:




a. A visual check of the ground around the building found a single piece of fibro cement sheet debris to the northeast. It is not possible to determine if this is the same piece described in the SWE reinspection report from December 2014.

The entire piece was taken as a sample by Robson’s ACT Licensed Asbestos Assessor during the reinspection. Subsequent analysis determined this material to be ACM. The analysis report is included as Appendix A. Recommendations include:

i. Remove this ACM entry from the ANU Building 28 Hazardous Material Register as no other pieces of ACM sheet debris were observed.

ii. Generate and communicate a response plan so future ACM occurrences can be reported and disposed of as they are discovered because it is possible for more ACM sheet debris to be uncovered/unearthed in the future. The exposure risk associated with these potential and random occurrences of future ACM sheet debris do not warrant a thorough environmental site cleanup and can be disposed of as additional ACM sheet debris, if discovered.

2. This finding from the September 2017 reinspection is in addition to the findings of the

SWE reinspection report from December 2014:

a. A visual check of the crawl space beneath the building found fibro cement sheet packers on top of the stumps.


A representative sample was taken by Robson’s ACT Licensed Asbestos Assessor during the reinspection. Subsequent analysis determined this material to be ACM. The analysis report is included as Appendix A. Since the ACM sheet packers are in good condition and as this area is relatively inaccessible, it is anticipated that works within this crawl space should not disturb the ACM sheet packers. Therefore the packers may remain in situ. Recommendations include:

i. Update the current ANU Building 28 Hazardous Materials Register to include ACM sheet packers in the crawl space. This will allow them to be checked during the next scheduled hazardous material reinspection (<5 years).

ii. Label all entry points to the crawl space to identify the presence of asbestos.

iii. Restrict access to the crawl space through the use of padlocks and nominate authorised staff to be the key holders.

iv. Remove the ACM sheet packers prior to any refurbishment or demolition that may disturb them.

3. This finding from the September 2017 reinspection is in addition to the findings of the SWE reinspection report from December 2014.

a. A visual check of existing building materials found fibro cement sheet infills above the east doorway/windows of Porch 1.12, the west doorway/windows of Deck 1.01 and above the east and west doorway/windows of Room 1.11..


A representative sample was taken by Robson’s ACT Licensed Asbestos Assessor during the reinspection. Subsequent analysis determined this material to be ACM. The analysis report is included as Appendix A.

Since the upper ACM sheet infills are in good condition, are fully encapsulated with paint and will not be disturbed during normal building occupancy, they may remain in situ. Recommendations include:

i. Update the current ANU Building 28 Hazardous Materials Register to include ACM sheet infills in Porch 1.12, Deck 1.01 and Room 1.11. This will allow them to be checked during the next scheduled hazardous material reinspection (<5 years).

ii. Label the ACM sheet infills to identify the presence of asbestos.

iii. Remove the ACM sheet infills prior to any refurbishment or demolition that may disturb them.

4. This finding from the September 2017 reinspection is in addition to the findings of the SWE reinspection report from December 2014:

a. The dark cream paint on the lower wall, door and door frame in Room 1.04 (kitchen) was determined to contain 8.3% by concentration weight per weight (w/w) lead. This is lead paint as defined by Australian Standard (AS 4361.2 – 1998 Guide to lead paint management Part 2: Residential and Commercial

buildings) and must be maintained as described in the SWE reinspection report from December 2014. No further action recommendations are required.


5. This finding from the September 2017 reinspection is in addition to the findings of the SWE reinspection report from December 2014:

a. All other paints tested in the last reinspection were deemed to be lead free because they were below the threshold criteria of 1.0% w/w lead.

Lead paint is defined by the Australian Standard (AS 4361.2 – 1998 Guide to lead paint management Part 2: Residential and Commercial buildings) as a paint or component coat of a paint system containing lead or lead compounds, in which the lead content (calculated as lead metal) is in excess of 1.0% by weight of the dry film as determined by laboratory testing.

Samples of the green paint on external window frames, door frames and handrails and the cream paint on external windows and doors were determined to contain 0.40% and 0.59% w/w lead respectively. Robson follow the recommendations of the Standard for the Uniform Scheduling of Drugs and Poisons (National Drugs and Poisons Schedule Committee July 2000) that classifies paints having more than 0.25% lead as First Schedule Paint and prohibits their manufacture, supply or use. It has been shown that the dust generated from dry sanding or abrasive blast cleaning of paints with a lead concentration of > 0.25% can have sufficient content to produce exposure levels that exceed those that define a ‘lead task’ in NOHSC 1012.

Therefore, paints with a lead concentration greater than 0.25% (if they are to be removed) must be treated as a lead paint (i.e. subject to the regulations in NOHSC 1012). Analytical values of <0.25% Pb allow the sample to be categorised as being lead free paint.

Recommendations include:

i. These two paint occurrences be changed from lead free paint to lead paint in the ANU Building 28 Hazardous Materials Register. This will allow them to be checked during the next scheduled hazardous material reinspection (<5 years).

Additional Learnings

1. There are no additional learnings from the reinspection of Building 28.

Removal of Asbestos as a Control Option

If removal of ACM is the preferred control option, it must be undertaken by a licensed Asbestos Removalist in accordance with current legislation. The removal/remediation of friable ACM must be undertaken by a licensed Class A Asbestos Removalist. Removal or remediation of non friable asbestos may be undertaken by either a Class A or Class B Asbestos Removalist.

Prior to the commencement of any removal or remediation works associated with any amount of friable or non friable asbestos a building certifier must be engaged and building approval granted. An application must be submitted to WorkSafe ACT and Comcare (if required) at least 5 days prior to removal works commencing. An asbestos removal contractor must supply an Asbestos Removal Control Plan (ARCP) and a Safe Work Method Statement (SWMS). An independent licensed Asbestos Assessor should be engaged to ensure that the ARCP addresses all safety issues relating to the planned asbestos works.

Air monitoring is mandatory during the removal or remediation of friable asbestos and should be considered during the removal or remediation of non friable asbestos. Air sampling is to be undertaken in accordance with the Guidance Note on the Membrane Filter Method for

Estimating Airborne Asbestos Fibres, 2nd Edition and test certificates should be NATA endorsed.

An independent Asbestos Assessor must also be employed to undertake a Clearance Inspection of both friable and non friable asbestos removal or remediation works. A satisfactory clearance certificate for the remediated areas must ensure that no visible asbestos or presumed asbestos remains. Additionally no asbestos fibres should be detected by laboratory analysis if any validation samples are taken. All surfaces within the remediated area must be free of general dust and debris.

STANDARD LIMITATIONS OF CLEARANCE INSPECTIONS (ACT) A visual clearance inspection is an inspection of a hazardous material removal area after lead paint removal work has been completed to verify that the area is safe for normal use, that: (a) includes a visual inspection, and (b) may include air monitoring”. The surface area and immediate vicinity has been visually determined to be clear of visible lead paint debris and or residue as specified for remediation. This clearance certificate is valid for areas which were visually accessible at the time of inspection as detailed in the scope of works.

Inspections are only carried out to the areas detailed to be removed and are conducted where access is available. Specifically, no inspection has been carried out to areas that may require further remediation to verify the presence of other hazardous materials. Please note that the visual clearance is limited to the surface of material(s) and/or soil(s) which were safely accessible at the time of inspection.

It should be noted that no inspection can be regarded as absolute and that additional hazardous materials may be encountered or uncovered upon further inspection, building works, or in particular excavations. The inspection was carried out at the time of the completion of the remediation works and was dependent upon site conditions at that time. WSP Australia accepts no responsibility or liability for the completeness of the hazardous material removal. Comments above regarding the aspects of the inspection also form limitations. The contractor’s responsibilities included:

— Ensuring that work methods and procedures comply with the relevant legislation, codes of practice and industry standards, and undertake work in accordance with technical specifications.

— Employing suitably trained, skilled and competent staff.

— Ensuring that contractors are inducted in safe work procedures for hazardous materials/products.

— Obtaining the necessary approvals from regulatory authorities prior to starting any hazardous materials removal or maintenance activities.

— Ensuring that all work is conducted in a safe and competent manner.

LIMITATIONS This report has been prepared for the benefit of the client and no other party. WSP assumes no responsibility and will not be liable to any other person or organisation for or in relation to any matter dealt with or conclusions expressed in the report, or for any loss or damage suffered by any other person or organisation arising from matters dealt with or conclusions expressed in the report (including without limitation matters arising from any negligent act or omission of WSP or for any loss or damage suffered by any other party relying upon the matters dealt with or conclusions expressed in the report). Other parties should not rely upon the report or the accuracy or completeness of any conclusions and should make their own enquiries and obtain independent advice in relation to such matters.

In accordance with the scope of services, WSP has relied upon the data and has conducted field monitoring and/or testing in the preparation of the report. The nature and extent of monitoring and/or testing conducted is described in the report. On all sites, varying degrees of non-uniformity of conditions are encountered. Hence no monitoring, common testing or sampling technique can eliminate the possibility that monitoring or testing results/samples are not totally representative of actual situations. The conclusions are based upon the data and the field monitoring and/or testing and are therefore merely indicative of the conditions of the site at the time of preparing the report.

It should also be recognised that site conditions, including the extent and concentration of contaminants, can change with time.

— Within the limitations imposed by the scope of services, the monitoring, testing, sampling and preparation of this report have been undertaken and performed in a professional manner, in accordance with generally accepted practices and using a degree of skill and care ordinarily exercised by reputable Occupational Hygiene consultants under similar circumstances. No other warranty, expressed or implied, is made.
