1 Executive Summary

1.1 Purpose

This Asbestos Survey & Management Plan (ASMP) for Mount Stromlo Observatory, Cotter Road, Block 38, Weston Creek ACT was commissioned by ANU in order to ensure the occupants receive the highest standards of occupational health and safety in relation to asbestos. The implementation of this Management Plan will assist the client in protecting the occupational health and safety of the occupants and address the regulatory requirements of a person with Management or Control of the Workplace (PMCW) in relation to asbestos in the premises.

1.2 Scope

Hazardous materials assessed included ACM, SMF, PCBs, lead containing paint, ODS and A/UST. The survey commenced on 31 January 2019 to 12 March 2019.

The aim of the survey was to assess the extent, location and condition of Asbestos Containing Material (ACM) on the Mount Stromlo Observatory common areas, roads and bike trails only Materials in similar locations which were visually consistent with those which have been identified as being an ACM are to be considered as being identical.

1.3 Method

The survey involved a visual inspection and subsequent sampling and analysis of collected samples by Robson’s National Association of Testing Authorities (NATA) accredited laboratory using polarised light microscopy. Samples were a representative selection of materials suspected of containing asbestos. Materials were not sampled from all areas due to the uniformity of the materials used.

All site surveying, sampling, laboratory analysis and reporting is in accordance with Robson Environmental’s NATA, ISO9001, AS4801 and ISO14001 accreditations.

The information contained in this document will assist the PMCW to fulfil their obligations under the latest editions of the following codes, regulations/Acts:

How to Manage and Control Asbestos in the Workplace Code of Practice

How to Safely Remove Asbestos Code of Practice

Dangerous Substances (General) Regulation 2004

Refer to Section 1.4 - Table 1B for presumed ACMs and Section 2.2 for exclusions


Table 1B: Presumed ACM, concealed locations and required actions

Type ACM Locations Action to be taken

The materials listed below while not identified on site, should be presumed to be present until a destructive survey confirms otherwise

Presumed ACM

Asbestos cement sheet formwork and electrical cable duct / water pipe debris

Subterranean areas

Any excavation works in the areas or

adjacent areas where ACM has been

identified should be undertaken by

qualified Asbestos personnel under the

supervision of an Asbestos Assessor.

Prior to any planned demolition, refurbishment or maintenance, its effect upon any in situ asbestos must be established by reference to this document including amendments.


Recommendations

The GPS coordinates for all ACM finds were recorded. Please refer to Appendix B – Plans.

The majority of the observed ACM was located within the footprints of the building sites which had burned down in previous bush fires. The ACM consisted of small fragments which appear to be predominately on the soil surface and are likely to be remnant waste from previously demolished / degraded infrastructure or illegal dumping on site.

ACM was observed to the areas outside these footprints but at a reduced frequency. A significant dump (C1490) was discovered down slope and west of the visitor’s car park adjacent one of the dirt access tracks. Buried asbestos debris may be present beyond the perimeter of the above specified areas. Care must be taken when excavation works are carried out in the contaminated and adjacent areas because asbestos debris may be uncovered at depth.

In ground service pits identified as T15 – T18 in the plans were identified as containing asbestos. These pits are in poor condition and should be removed by a licensed asbestos removalist.

All other in ground service pits identified as T1-T14 in the plans were identified as containing non-asbestos cement sheet.

All ACM finds on site are categorized as non-friable ACM in poor condition.

The presence of the asbestos poses a low risk to site occupants (including the general public). However the areas of impact should either be cordoned off and appropriately sign posted to prevent access to unauthorized personnel or the asbestos removed by hand (‘chicken picked’) by an ACT licensed asbestos removalist.

Due to the extent of the sporadic finds across the site it has also been assessed that it is unlikely that all the ACM will be able to be removed successfully from the site. Therefore Robson recommends an asbestos management plan (AMP) with an unexpected finds protocol (UFP) be developed for the site to manage all ACM finds into the future.

ACM must not be drilled, cut, sanded, damaged or abraded and a good paint finish maintained. Asbestos work on non friable ACM may be undertaken by a licensed Class A or B Asbestos Removalist. Any works on, or in the vicinity of friable ACM must only be undertaken by a licensed Class A Asbestos Removalist.

The Asbestos Register including any risk assessments should be reviewed within the time period recommended by the Asbestos Assessor in 4.2 Asbestos Register Table 3A or earlier where:

- A risk assessment indicates the need for reassessment or - Any ACM has been disturbed or moved

ACM should be labelled with approved asbestos warning labels or signs. Due to the stigma associated with asbestos and to avoid malicious damage to ACM, labelling can be kept to discrete areas. Where labelling cannot be undertaken, the PMCW must adopt strict administrative controls to ensure ACM is not subject to accidental damage.


Asbestos Removal

Removal of ACM 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 an A or B Class 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 (where applicable) 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 either 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.


2 INTRODUCTION

This ASMP is designed to address the safe control of ACM identified by Robson Environmental Pty Ltd in the premises. It is also designed to address any future asbestos findings.

This ASMP contains sections covering the identification, evaluation and control of asbestos hazards which were identified during the survey.

2.1 Requirements for the Asbestos Survey & Management Plan

The PMCW must retain a copy of this ASMP and it must be distributed to tenants. Prior to any repair, maintenance or building works to the premises, all stakeholders must be provided with a copy of this ASMP.

Maintenance, trades and other personnel must be instructed not to remove or damage identified or suspected ACM. If ACM is identified in the area where work is to be undertaken the ACM must be removed prior to the work commencing.

Removal of ACM must be undertaken by an ACT licensed Asbestos Removalist in accordance with current legislation.

This ASMP includes the following:

A register of all known ACM Extent, form, condition and risks associated with the ACM Labelling requirements for ACM Safe work methods, removal methods and training requirements Responsibilities of all persons involved in ACM management Procedures to address incidents or spillage involving ACM A timetable for managing risks, including priorities for removal or control of ACM

according to risk and timetable for reviewing risk assessments A procedure for reviewing and updating the ASMP and register of ACM, including a

timetable

This ASMP addresses the current requirements for asbestos management and therefore must be updated as required to reflect legislative changes. The asbestos register and associated risk assessment within this ASMP is designed to be reviewed by a licensed Asbestos Assessor at the intervals shown in 4.2 Asbestos Register Table 3A.

Where ACM has been disturbed, removed, enclosed, encapsulated, sealed or its condition has deteriorated, the existing asbestos risk assessment will no longer be valid and the ASMP will need to be reviewed by the licensed Asbestos Assessor to reflect these changes. Each review should critically assess all the asbestos management procedures and their effectiveness in:

Preventing exposure to asbestos Controlling access to asbestos Highlighting the need for action to maintain or remove ACM Maintaining the accuracy of the ASMP

Details of any mitigating factors must be recorded in the Asbestos Register (refer 4.2 Table 3A).


2.2 Exclusions

The HMSMP commissioned by the client was to be non-destructive and non-intrusive in nature. This type of commission limits or restricts access to the building structure, some surfaces and materials. No determination can be made regarding the possibility of concealed or inaccessible ACM without gaining access to areas that are not readily accessible to allow for inspections.

Unless specifically noted, the survey did not cover exterior ground surfaces, sub-surfaces (e.g. infill/soil) or items such as materials in laboratories or special purpose facilities.

When any building works are undertaken, care should be taken to determine the existence or otherwise of ACM. As a precaution, all materials that may, or are likely to contain asbestos should be assumed to contain asbestos and be treated appropriately until laboratory analysis confirms otherwise. If, during building works, ACM is located, those works should cease in the areas of concern and a licensed Asbestos Removalist contacted immediately to remove the material. A licensed Asbestos Assessor must issue a clearance certificate before works may recommence in the affected area.

Robson Environmental Pty Ltd recommends that prior to any works, our office be contacted. Our Asbestos Assessors can attend the site to observe the works process, advise as necessary, and in the event of asbestos being located, assist with assessing the extent of ACM. Further, Robson Environmental Pty Ltd provides all occupational hygiene services in relation to asbestos removal.

2.3 Limitations

Although all reasonable care and attention is taken in compiling this report, no guarantee as to its accuracy or completeness can be given. This may be a result of:

normal construction practices of 'building in' some ACM (i.e. during previous renovations or additions)

the random application of asbestos materials other physical or applied constraints on our investigation

Our report is limited by the physical constraints of the structure under investigation. Prior to any refurbishment or hazardous material removal projects, the contractor(s) carrying out the work must fully acquaint themselves with the extent of the hazardous materials, particularly in those areas which may require full or partial demolition, in order to determine the exact extent and location of these materials.

Although extensive, this ASMP must not be used as a specification or method statement for any future asbestos removal project. In these circumstances, detailed plans and quantities would be required.

4 ASBESTOS RISK ASSESSMENT

4.1 Introduction

The purpose of the risk assessment is to enable informed decisions to be made concerning the control of ACM. The risk assessment should take into account the information in the Asbestos Register including:

the type of ACM (friable or non friable) the condition and location of ACM whether the ACM is likely to be disturbed due to its condition and location the likelihood of exposure

Types of ACM

Non friable ACM

Non friable asbestos (previously known as bonded asbestos) is any material that contains asbestos firmly bound into a matrix. It may consist of cement or various resins/binders and cannot be reduced to a dust by hand pressure. As such it does not present an exposure hazard unless cut, abraded, sanded or otherwise disturbed. Therefore, the exposure risk from non friable ACM is negligible during normal building occupation.

Note: if non friable ACM is damaged or otherwise deteriorated, the risk assessment must be reviewed to reflect a higher potential for exposure to asbestos fibres. Severely damaged, non friable ACM may be assessed as being friable. A licensed Asbestos Assessor must perform the risk assessment.

Friable ACM

Friable asbestos material can be crumbled or reduced to a dust by hand pressure when dry. It can represent a significant exposure hazard as a consequence of minor disturbance. Examples of friable asbestos are hot water pipe lagging, severely damaged asbestos cement sheet, limpet spray to structural beams and electrical duct heater millboard.


ACM CONDITION RATING

1 Severe Friable: Readily accessible, deteriorated surface in extremely poor condition

2 Poor Friable: Unstable material that is relatively accessible Non friable: Readily accessible, deteriorated surface

3 Normal Friable: Stable asbestos that is relatively inaccessible Non friable: Accessible surfaces in fair condition

4 Good Non friable: Well sealed stable surfaces in accessible locations

ACM RISK RATING

A Very High Friable: Exposure to airborne asbestos as a consequence of extremely minor disturbance

B High

Friable: Exposure to airborne asbestos occurs as a consequence of minor disturbance Non friable: Exposure to airborne asbestos likely as a consequence of significant disturbance

C Medium

Friable: Exposure to airborne asbestos unlikely during normal building use Non friable: Exposure to airborne asbestos highly unlikely during normal building use

D Low Non friable: No exposure to airborne asbestos during normal building use


4.2 Asbestos Register

The Asbestos Register details the type, location, risk rating and action required for all identified ACM. The register should be accessed to inform all decisions made concerning the control of ACM. Action taken to control ACM must be recorded in this register in order to comply with current legislation.

4.3 Risk Assessment

Control Measures General Requirements

Any ACM which is not scheduled for immediate removal should be fenced off to prevent disturbance and appropriate signage displayed..

The details of any deterioration or removal must be entered into the ACM register. All site personnel must be made aware of the location of ACM. The Asbestos Register must be distributed to all stakeholders. Unless holding a valid Asbestos Removal Licence, maintenance all site personnel shall not

remove or knowingly damage identified, presumed or suspected ACM. Prior to any earth works which are likely to disturb the contaminated or adjacent areas its

effect upon any in situ asbestos must be established by reference to this document, including amendments.

Recommended Control Measures for the Premises

Identified, presumed or suspected ACM should be fenced off and approved asbestos warning labels or signs displayed. Where labelling is not practicable, strict administrative controls must be in place to ensure ACM is not subject to accidental damage or misuse.

Prior to any planned demolition, refurbishment or maintenance, its effect upon any in situ asbestos must be established by reference to this document, including amendments.

The asbestos register and associated risk assessments within the ASMP are designed to be reviewed by a licensed Asbestos Assessor at intervals stated in 4.2 Asbestos Register Table 3A.

Where an ACM has been disturbed, removed, enclosed, encapsulated, sealed or its condition has deteriorated, the existing asbestos risk assessment will no longer be valid and the ASMP will need to be revised by a licensed Asbestos Assessor to reflect these changes. – refer section 2.1.

Demolition or any other works within areas where asbestos is located is not to take place until the asbestos removal works have been completed and a Clearance Certificate issued by a licensed Asbestos Assessor.

Note: Buried asbestos debris may be present beyond the perimeter of the above specified areas. Care must be taken when excavation works are carried out in the contaminated and adjacent areas because asbestos debris may be uncovered at depth.


5 ASBESTOS MANAGEMENT

7 ASBESTOS REMOVAL WORKS

7.1 PMCW Responsibilities

Where it has been determined that ACM is to be removed, the PMCW must ensure that a risk assessment is performed prior to the removal works, and that the removalist takes this risk assessment into account. This risk assessment must include the possibility of uncovering previously concealed ACM and ensuring concealed ACM is identified by a licensed Asbestos Assessor. The PMCW should provide a detailed scope of works for the Asbestos Removalist, including potential hazards, details about areas which may contain asbestos and arrangements for clearance inspections and air monitoring.

7.2 Removalist Responsibilities

Prior to the commencement of removal works, the licensed asbestos removal contractor must:

provide a site-specific Asbestos Removal Control Plan (ARCP) ensure the removal is adequately supervised and carried out in a safe manner ensure all persons carrying out the removal are competent and trained for the type of work

being carried out demonstrate that they have a health surveillance program in accordance with current

legislation.

7.3 Approval to Begin Asbestos Removal Works

All removal methods and procedures are required to be undertaken in accordance with current legislation. The PMCW in conjunction with an Asbestos Assessor will inform the Asbestos Removalist of the Scope of Work. The Asbestos Assessor will be required to provide a clearance certificate on satisfactory completion of the works.

7.4 Work in Areas Containing Asbestos – Trades Personnel

Prior to commencement of works the following undertakings, procedures and awareness must be observed: Work must not proceed under any circumstance without first contacting the PMCW. Refer to this ASMP (including amendments) to determine if ACM are likely to be encountered in the general work area. If no ACM is located in the area of intended work, the area may be entered by all relevant personnel on an unrestricted basis. Work in areas where ACM will, or is likely to be disturbed will only be given to ACT licensed Asbestos Removalists and all access and works will be in accordance with current legislation.

7.5 Emergency Work in Areas Containing Asbestos

If emergency work is required, contact the PMCW. If the PMCW determines that asbestos is likely to be encountered a licensed Asbestos Removalists must undertake any asbestos removal or remediation works.


Telephone WorkSafe ACT for emergency approval of asbestos work. Advise WorkSafe ACT in writing within 24 hours.

A licensed Asbestos Assessor will be required to provide a clearance certificate on satisfactory completion of the works.

7.6 Monitoring Arrangements

To ensure control measures are effective, air monitoring should be performed whenever friable ACM is being removed from buildings. A Risk Assessment may also require that air monitoring is undertaken during or at the completion of the removal of non friable ACM.

All air monitoring must be performed by a competent person accredited to perform air sampling for asbestos. Sampling should be performed in accordance with the ‘Guidance Note on the Membrane Filter Method for Estimating Airborne Asbestos Fibres [NOHSC: 3003 (2005)].

It is the Asbestos Removalist’s responsibility to ensure that the maximum fibre levels throughout asbestos removal and associated works do not equal or exceed the minimum practical detection limit of 0.01 fibres per millilitre of air (f/mL). The consequences of airborne fibre levels observed at or exceeding those specified below will result in the Asbestos Assessor instructing the contractor to take the appropriate ‘Control /Action’ as listed below.

Control Level

(airborne asbestos fibres/mL) Control / Action

< 0.01 Continue with control measures

0.01 Review control measures

0.02 Stop removal work and find the cause

7.7 Clearance Inspections Prior To Re-Occupation

Following removal work, a clearance inspection must be undertaken prior to re-occupation of an asbestos work area. This shall be conducted by a licensed Asbestos Assessor.

All barriers and warning signs should remain in place until the area has been cleared.

7.8 ACM removal/maintenance record

The Asbestos Register, Section 4.2, Table 3A, is to be completed by the PMCW after receiving appropriate clearance certification from a licensed Asbestos Assessor.

1 Introduction

Lead (Pb) paint is defined by the Australian Standard AS 4361.2 – 2017 (Guide to hazardous paint management Part 2: Lead paint in residential, public 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 0.1% by weight of the dry film as determined by laboratory testing.

Analytical values of ≤ 0.1% Pb allow the sample to be categorised as being lead free paint.

It should be noted that this Standard relates only to the removal of lead paint. In the ACT and NSW, building waste which is painted with lead paint may be disposed of as general demolition waste regardless of the quantity or percentage of lead paint.

Lead in paint (as lead carbonate) is found extensively in homes and commercial and industrial buildings built pre-1970. Although Australian industry has generally phased out lead in paint, levels of below 1 percent are still permitted and industrial application of high-lead paint to residential/commercial dwellings may still continue (Standards Australia, 2017).

Lead-based paint may be a health issue if it becomes mobile in the environment or if ingested. For this reason, sealing or safe removal of paint is strongly recommended, particularly where it is flaking or exposed to the elements.

2 Survey Methodology

Robson Environmental Pty Ltd conducted an assessment for lead-based paint for the Australian National University at Mount Stromlo Observatory on 15/04/2019. The assessment was targeted to the General Site and included information from a previous site visit on 07/02/2019.

The paint samples were qualitatively tested using 3M™ LeadCheck™ Swabs. These are USA EPA-recognised for the determination of lead-based paint with a 600ppm lower detection limit. This is equivalent to 0.06% and is therefore appropriate for the categorisation of tested surfaces as being lead free paint.

If the 3M™ LeadCheck™ Swabs detected the presence of lead, the paint sample was categorically deemed to be lead paint regardless of the number of lead and/or non-lead paint layers present within the sample tested. At the client’s request, additional samples of the paints tested with the 3M™ LeadCheck™ Swabs were not sent for further laboratory analysis to determine the exact percentage of lead present in the paint for all but one of the paint systems.

One sample was sent for quantitative analysis for lead concentration following the method stated in Appendix A of AS/NZS 4361.2. The sample was individually sealed and double bagged, and couriered under Chain of Custody (COC) documentation to Envirolab in Sydney NSW.


During the lead paint survey, the following criteria were considered by a Licensed Asbestos Assessor

(or competent person) when assessing the risk associated with lead paint systems. This qualitative

assessment determines the Risk Rating. These are shown in Table 1.

Location of the lead paint system

Surface area of the lead paint system

Condition of the lead paint system

Accessibility of the lead paint system

Likelihood of ingesting and/or inhaling lead paint particles

Table 1: Risk Rating Levels and Action Plan

Risk Rating Level Action Plan

High

(H)

Lead is present in paint that is in very poor condition (i.e. bad cracking, flaking, chalking and peeling observed). It covers a large surface area and/or is on a surface that is easily accessible to children.

It may present a health hazard with minor disturbance.

Action should be taken immediately to reduce exposure risk.

Medium

(M)

Lead is present in paint that is in average condition (i.e. some cracking, flaking, chalking and peeling observed). It covers a small surface area and/or is on a surface that is not easily accessible to children.

It may present a health hazard with moderate disturbance.

Action should be taken as soon as practicable to reduce exposure risk.

Low

(L)

Lead is present in paint that is still in good condition (i.e. no cracking, flaking, chalking or peeling observed) and is not a friction or impact surface.

It is not likely to present a health hazard unless significantly disturbed.

Ongoing actions to maintain the lead paint system in good condition and to check it periodically to ensure a low exposure risk.

Nil

(N)

Lead was not detected in paint system being assessed.

No action required.


3 Results and Recommendations

The quantitative laboratory results analysed from the sample collected on 07 February 2019 show that one lead paint system contained lead concentrations in excess of the 0.1% by weight threshold. These paints are required to be managed as lead paint so risk can be minimised. Please note that AS/NZS 4361.2 states that if ‘one or more tests from a building or portion of a building indicate that lead is present, the paint should be treated as lead paint’.

The qualitative swab results collected on 15 March 2019 show that four lead paint systems contain lead concentrations in excess of the 0.1% by weight threshold. These paints are required to be managed as lead paint so risk can be minimised. Please note that AS/NZS 4361.2 states that if ‘one or more tests from a building or portion of a building indicate that lead is present, the paint should be treated as lead paint’.

The results also show that one lead paint system may be considered lead-free because no lead was detected in the paint samples as tested with the 3M™ LeadCheck™ Swabs. This shows that the concentration is below the definition for lead paint and the paint system poses no risk.

Table 1 presents lead composition in paints, with results shown as a ‘yes’ or ‘no’ for the presence of lead within the paint samples tested as well as the exact percentage of lead determined through laboratory analysis. Recommendations suitable for the relevant lead paint system risk rating are also explained here. Photographs of samples are included in Appendix 1, the full laboratory report is in Appendix 2 and the plans are in Appendix 3.

4 Remediating Surfaces Containing Lead Paint

The main exposure risk associated with lead paint is when it becomes an airborne dust or fume.

When paint deteriorates through chipping, cracking, bubbling and flaking, it is not becoming an

airborne dust and cannot be easily inhaled.

The key to safely remediating surfaces containing lead paint is to prevent the generation of dust and

fume. As a result, sanding, buffing, grinding, burning and wet/dry abrasive blasting is not

appropriate. Abrasive blasting is defined as propelling a stream of abrasive material at high speed

against a surface using compressed air, liquid, steam, centrifugal wheels or paddles to clean, abrade,

etch or otherwise change the original appearance or condition of the surface.

In fact, Safe Work Australia prohibits abrasive blasting of lead materials and lead paint systems above a concentration of 0.1% by weight. Refer to https://www.safeworkaustralia.gov.au/chemicals.

To safely remediate surfaces containing lead paint, the following method is acceptable:

1. If indoors, shut all windows and doors to enclose the work area and place heavy duty plastic

sheets on the floor to ease clean up.

2. If outdoors, plan your work for a day that is not windy and when rain is not predicted. Cover

the ground below the painted surface with heavy duty plastic sheeting. For example, strips

that are two metres wide would be suitable for the external wall of a house.

3. Workers are to:

a. Be clean shaven.

b. Wear appropriate respiratory protection. A minimum of P1 is essential but P2

respirators (i.e. disposable masks) are preferred.

c. Wear gloves.

d. Wear a hat to prevent lead paint chips from getting stuck in hair and being

accidentally removed from the area.

e. Wear disposable coveralls to prevent lead paint chips from getting into pockets,

stuck to sweaty skin or getting inside work shirts, etc. and being accidentally

removed from the area. Note: Workers need to be aware of and prevent heat-

related illness, maintain good hydration, take rest breaks in the shade, have cool

drinking water available and avoid working during the hottest parts of the day if

wearing disposable coveralls.

f. Wash hands and face before eating, drinking and smoking to prevent hand-to-month

cross contamination.

4. Manually scrape all loose paint off the surface so the flakes fall on the plastic sheets. Note:

no grinding, buffing, sanding, abrasive blasting, burning, etc.

5. When complete, fold up the plastic sheets to collect all the paint scrapings and dispose of

them appropriately.

6. The surface can be repainted to bind the remaining lead paint to the structure. Several coats

may be required to adhere all old paint to the structure again.

7. Next, the paint flakes that are already on the ground can be addressed:

a. Regarding sealed surfaces, such as concrete, bitumen, timber or tiles:

i. Paint chips can be vacuumed up.

https://www.safeworkaustralia.gov.au/chemicals


ii. The vacuum bag contents should then be carefully transferred to a heavy

duty plastic bag to prevent dust from being released. Note: do not overfill

the bags as they will become a manual handling risk and could tear open

under the weight.

iii. Dispose of the waste appropriately.

b. Regarding unsealed surfaces, such as dirt, rocks or grass:

i. Wet the ground around the surface with a fine mist (not a heavy spray) or a

diluted PVA glue solution to prevent dust from being generated in the next

steps.

ii. Use a shovel to manually scrape approximately 10mm to 15mm of loose dirt

and rocks from the top surface of the ground and collect it in heavy duty

plastic bags. Note: do not overfill the bags as they will become a manual

handling risk and could tear open under the weight.


8. Continue to inspect the condition of the paint every 5 years to assess whether further

deterioration has occurred.

9. Repeat this process whenever the paint system deteriorates to a point where remediation is

required.

10. In the event that a structure containing a lead paint system is nominated for demolition:

a. Refer to the additional recommendations shown in the next section of this report.

b. Plastic sheets are unnecessary as they will get easily ripped up and damaged.

c. Workers need to be clean shaven and wear respiratory protection, gloves and

exercise proper personal hygiene during the period they are handling lead painted

materials.

d. Personal Protective Equipment (PPE) requirements can be reassessed once all the

components containing a lead paint system are gone and only non-lead paint

systems remain.

e. After the entire structure is gone, the ground will need to be scraped back to collect

all residual paint flakes as described above.


5 Additional Recommendations for the Demolition and Disposal of

Building Waste Containing Lead Paint

In the ACT & NSW, building waste painted with lead paint is classified as general building waste and may be disposed of without removing the lead paint. As a result, it is recommended that all materials that tested positive for the presence of lead paint be disposed of as general building waste.

The mechanical demolition of structures and objects painted with lead paint do not fall under the category of a ‘lead process’ as defined by the ACT Work Health and Safety Regulations 2011 (Section 392) so the requirements of Part 7.2 in the Regulations do not apply. Refer to https://www.legislation.act.gov.au/View/sl/2011-36/current/PDF/2011-36.PDF.

Only if you are intending to remove the paint from the structures/objects so they may be reused, recycled or refurbished, should the lead paint be removed in strict accordance with the methods specified in AS/NZS 4361.1 and AS/NZS 4361.2.

Due to similarities between environmental cleaning methods for lead paint and asbestos containing materials, it is recommended that a Class B licensed Asbestos Removalists be used to remove lead paint from materials being reused, recycled or refurbished.

Please note that it is not recommended to weld, cut or clean lead painted metal structures/objects using flame (i.e. electric arc, oxy gas, oxyacetylene, plasma arc, etc.) or abrasive cutting equipment that creates heat from friction (i.e. grinders, etc.) because it will burn the paint and generate fume containing lead. This falls under the definition of a ‘lead process’ as defined by the ACT Work Health and Safety Regulations 2011 (Section 392(i)) and the requirements of Part 7.2 of the Regulations apply.

It is recommended that only mechanical cutting methods that do not burn the paint be used (i.e. demolition shears) to avoid the requirements of Section 7.2 of the Regulations. Manually unbolting the pieces can also be done but this would be fairly time-consuming and heat should not be applied to stuck nuts/bolts as it will burn the lead paint.

1 Introduction

Lead (Pb) paint is defined by the Australian Standard AS 4361.2 – 2017 (Guide to hazardous paint management Part 2: Lead paint in residential, public 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 0.1% by weight of the dry film as determined by laboratory testing.

Analytical values of ≤ 0.1% Pb allow the sample to be categorised as being lead free paint.

It should be noted that this Standard relates only to the removal of lead paint. In the ACT and NSW, building waste which is painted with lead paint may be disposed of as general demolition waste regardless of the quantity or percentage of lead paint.

Lead in paint (as lead carbonate) is found extensively in homes and commercial and industrial buildings built pre-1970. Although Australian industry has generally phased out lead in paint, levels of below 1 percent are still permitted and industrial application of high-lead paint to residential/commercial dwellings may still continue (Standards Australia, 2017).

Lead-based paint may be a health issue if it becomes mobile in the environment or if ingested. For this reason, sealing or safe removal of paint is strongly recommended, particularly where it is flaking or exposed to the elements.

2 Survey Methodology

Robson Environmental Pty Ltd conducted an assessment for lead-based paint for the Australian National University at the Mount Stromlo Observatory Oddie Telescope on 15/04/2019.

At the client’s request, paint samples were not qualitatively tested using 3M™ LeadCheck™ Swabs because identifying the exact percentage of lead present in the paint was requested. Qualitative testing can only give a ‘yes’ or ‘no’ for the presence of lead.

A paint sample of the relevant paint system was collected. The sample was sent for quantitative

analysis for lead concentration following the method stated in Appendix A of AS/NZS 4361.2.

All samples were individually sealed and double bagged, and couriered under Chain of Custody (COC) documentation to Envirolab in Sydney NSW.


During the lead paint survey, the following criteria were considered by a Licensed Asbestos Assessor (or competent person) when assessing the risk associated with lead paint systems. This qualitative assessment determines the Risk Rating. These are shown in Table 1.

Location of the lead paint system

Surface area of the lead paint system

Condition of the lead paint system

Accessibility of the lead paint system

Likelihood of ingesting and/or inhaling lead paint particles

Table 1: Risk Rating Levels and Action Plan

Risk Rating Level Action Plan

High

(H)

Lead is present in paint that is in very poor condition (i.e. bad cracking, flaking, chalking and peeling observed). It covers a large surface area and/or is on a surface that is easily accessible to children.

It may present a health hazard with minor disturbance.

Action should be taken immediately to reduce exposure risk.

Medium

(M)

Lead is present in paint that is in average condition (i.e. some cracking, flaking, chalking and peeling observed). It covers a small surface area and/or is on a surface that is not easily accessible to children.

It may present a health hazard with moderate disturbance.

Action should be taken as soon as practicable to reduce exposure risk.

Low

(L)

Lead is present in paint that is still in good condition (i.e. no cracking, flaking, chalking or peeling observed) and is not a friction or impact surface.

It is not likely to present a health hazard unless significantly disturbed.

Ongoing actions to maintain the lead paint system in good condition and to check it periodically to ensure a low exposure risk.

Nil

(N)

Lead was not detected in paint system being assessed.

No action required.


3 Results and Recommendations

The quantitative laboratory results analysed from the sample collected on 15 April 2019 show that one lead paint system contains lead concentrations in excess of the 0.1% by weight threshold. This paint is required to be managed as lead paint so risk can be minimised. Please note that AS/NZS 4361.2 states that if ‘one or more tests from a building or portion of a building indicate that lead is present, the paint should be treated as lead paint’.

Table 1 presents lead composition in paints, with results shown as the exact percentage of lead determined through laboratory analysis. Recommendations suitable for the relevant lead paint system risk rating are also explained here. Photographs of samples are included in Appendix 1 and the full laboratory report is in Appendix 2.

4 Remediating Surfaces Containing Lead Paint

The main exposure risk associated with lead paint is when it becomes an airborne dust or fume.

When paint deteriorates through chipping, cracking, bubbling and flaking, it is not becoming an

airborne dust and cannot be easily inhaled.

The key to safely remediating surfaces containing lead paint is to prevent the generation of dust and

fume. As a result, sanding, buffing, grinding, burning and wet/dry abrasive blasting is not

appropriate. Abrasive blasting is defined as propelling a stream of abrasive material at high speed

against a surface using compressed air, liquid, steam, centrifugal wheels or paddles to clean, abrade,

etch or otherwise change the original appearance or condition of the surface.

In fact, Safe Work Australia prohibits abrasive blasting of lead materials and lead paint systems above a concentration of 0.1% by weight. Refer to https://www.safeworkaustralia.gov.au/chemicals.

To safely remediate surfaces containing lead paint, the following method is acceptable:

1. If indoors, shut all windows and doors to enclose the work area and place heavy duty plastic

sheets on the floor to ease clean up.

2. If outdoors, plan your work for a day that is not windy and when rain is not predicted. Cover

the ground below the painted surface with heavy duty plastic sheeting. For example, strips

that are two metres wide would be suitable for the external wall of a house.

3. Workers are to:

a. Be clean shaven.

b. Wear appropriate respiratory protection. A minimum of P1 is essential but P2

respirators (i.e. disposable masks) are preferred.

c. Wear gloves.

d. Wear a hat to prevent lead paint chips from getting stuck in hair and being

accidentally removed from the area.

e. Wear disposable coveralls to prevent lead paint chips from getting into pockets,

stuck to sweaty skin or getting inside work shirts, etc. and being accidentally

removed from the area. Note: Workers need to be aware of and prevent heat-

related illness, maintain good hydration, take rest breaks in the shade, have cool

drinking water available and avoid working during the hottest parts of the day if

wearing disposable coveralls.

f. Wash hands and face before eating, drinking and smoking to prevent hand-to-month

cross contamination.

4. Manually scrape all loose paint off the surface so the flakes fall on the plastic sheets. Note:

no grinding, buffing, sanding, abrasive blasting, burning, etc.

5. When complete, fold up the plastic sheets to collect all the paint scrapings and dispose of

them appropriately.

6. The surface can be repainted to bind the remaining lead paint to the structure. Several coats

may be required to adhere all old paint to the structure again.

7. Next, the paint flakes that are already on the ground can be addressed:

a. Regarding sealed surfaces, such as concrete, bitumen, timber or tiles:

i. Paint chips can be vacuumed up.

https://www.safeworkaustralia.gov.au/chemicals


ii. The vacuum bag contents should then be carefully transferred to a heavy

duty plastic bag to prevent dust from being released. Note: do not overfill

the bags as they will become a manual handling risk and could tear open

under the weight.


b. Regarding unsealed surfaces, such as dirt, rocks or grass:

i. Wet the ground around the surface with a fine mist (not a heavy spray) or a

diluted PVA glue solution to prevent dust from being generated in the next

steps.

ii. Use a shovel to manually scrape approximately 10mm to 15mm of loose dirt

and rocks from the top surface of the ground and collect it in heavy duty

plastic bags. Note: do not overfill the bags as they will become a manual

handling risk and could tear open under the weight.


8. Continue to inspect the condition of the paint every 5 years to assess whether further

deterioration has occurred.

9. Repeat this process whenever the paint system deteriorates to a point where remediation is

required.

10. In the event that a structure containing a lead paint system is nominated for demolition:

a. Refer to the additional recommendations shown in the next section of this report.

b. Plastic sheets are unnecessary as they will get easily ripped up and damaged.

c. Workers need to be clean shaven and wear respiratory protection, gloves and

exercise proper personal hygiene during the period they are handling lead painted

materials.

d. Personal Protective Equipment (PPE) requirements can be reassessed once all the

components containing a lead paint system are gone and only non-lead paint

systems remain.

e. After the entire structure is gone, the ground will need to be scraped back to collect

all residual paint flakes as described above.


5 Additional Recommendations for the Demolition and Disposal of
