Report – Coarse Spodumene Concentrate Risk Asessment

21 February 2017 754-ENAUPERT04930AA – Fremantle Port Authority – Coarse Spodumene Concentrate Risk Assessment 1

EXECUTIVE SUMMARY

Coffey was engaged by Fremantle Port Authority to conduct a risk assessment of the receival, stockpiling

and out-loading coarse spodumene concentrate at Kwinana Bulk Terminal.

The level of risk to employee health from potential exposure has been determined to be low, considering the following factors:

The coarse spodumene concentrate product is wet sieved before delivery to KBT, removing the

vast majority of respirable dust.

The coarse spodumene concentrate has a high moisture concentration when delivered.

The concentration of respirable fibrous minerals observed in the coarse spodumene concentrates

by SEM/EDS analysis was low.

The quartz within the product is in large crystals and therefore poses a low risk to health. If this

material is ground in some way, it will generate respirable quartz and become a hazard.

The composition of the concentrate is unlikely to change significantly when different depths and

pits are mined because the concentrate is processed through a concentrator. It is important that

the mining company does not mine through the footwall or into the country rock of the pit face.

Fibres are hazardous if they are airborne and respirable in size. All fibre monitoring results were

well below the national exposure standard of 0.1 f/mL for respirable fibres.

Personal and static respirable dust monitoring results were below the national exposure standard

of 3.0 mg/m3.

Personal and static respirable silica monitoring results were below the national exposure

standard of 0.1 mg/m3.

The calculated exposure index for the additive atmospheric contaminants of fibres, respirable

dust and respirable silica was calculated to be less than one and therefore unlikely to cause harm.

The controls outlined in Section 5.4 should be continued or implemented to maintain a low risk of

exposure.



1 INTRODUCTION

Coffey was engaged by Mr Mark Pearce, Manager Bulk Business, Kwinana Bulk Terminal (KBT) of

Fremantle Port Authority, to conduct a risk assessment of coarse spodumene concentrate (spodumene).

Spodumene is a pyroxene mineral consisting of lithium aluminium inosilicate, LiAl(SiO3)2, and is a source

of lithium. The 15,000 tonnes of spodumene at KBT originated from the Mount Marion mine near

Kalgoorlie Boulder, WA and was stockpiled at Kwinana Bulk Terminal (KBT) and then loaded onto a ship

on 5 - 7 February 2017.

Mount Marion mine is located within the Greenstone mineralisation belt of WA. The Greenstone belt

contains amphibole minerals, which can be in asbestiform morphology/variety. The ore body being mined

could be variable, especially at the margins of the pegmatite intrusion. Dolerite and basalt are present on

the contact between the orebody and waste. Dolerite and basalt are minerals where amphibolite minerals

can occur. The area from which the spodumene was mined naturally contains actinolite and quartz,

amongst other identified minerals.

Sampling of bulk material detected actinolite and quartz in the spodumene stockpile. Airborne abestos

fibres and amphibole cleavage fragments, and respirable dust containing crystalline quartz, are potentially

hazardous to health if inhaled at harmful concentrations.

According to commentary on the Sampling Techniques and Data at Mount Marion during exploration

drilling, amphibole minerals were identified. Some bulk material sampling has been undertaken for fibres

at Mount Marion at various stockpiles in the past, however, the lack of sampling details has compromised

the accuracy of the data. Fibres were detected in routine sampling of the product by FPA.

The approximate number of employees working at Kwinana Bulk Terminal is 100 workers. Occupations

working in closest vicinity to coarse spodumene concentrate include the front end loader operators,

maintenance and ship loader operators.

1.1 Objectives

The risk assessment was undertaken to ascertain whether the coarse spodumene concentrate poses a

risk to the health of employees, contractors or visitors working at KBT while the spodumene is in the

workplace. It does not include an assessment of the fine spodumene float concentrate, which will require

an assessment of its own if it is exported through KBT.

1.2 Scope

The scope of work required Coffey to:

Mobilise a consultant and expert to and from the site.

Collect bulk material for SEM analysis.

Collect occupational air monitoring samples for respirable dust, respirable silica and fibres.

Conduct all air monitoring in accordance with the Methodology section.

Compare exposure results against relevant Australian exposure standards.

Record, collate and report the findings and providing appropriate recommendations for the control of

the risk of exposure, if necessary.



2 METHODOLOGY

In accordance with the Mines Safety and Inspection Regulations 1995, atmospheric contaminant monitoring was provided to determine the level of airborne contaminants in the workplace to which persons may be exposed.

Sampling was conducted in accordance with the following Regulations and Australian Standards (AS):

Adopted National Exposure Standards for Atmospheric Contaminants in the Occupational Environment [NOHSC: 1003(1995)]

Australian Standard AS 2985 – 2009 Workplace atmospheres - method for sampling and gravimetric determination of respirable dust.

Guidance Note on the Membrane Filter Method for Estimating Airborne Asbestos Fibres, 2nd Edition [NOHSC:3003 (2005)]

Analysis was conducted in accordance with the following methods:

Envirolab / MPL Asbestos ID – Qualitative indentification of asbestos in bulk samples using Polarised Light Microscopy and Dispersion Staining Techniques, including Synthetic Mineral Fibres and Organic Fibres as per Australian Standard 4964-2004

Greencap – X-ray Diffraction (XRD) for total quartz content of coarse spodumene concentrate

MicroAnalysis Australia analysed the respirable alpha-quartz concentration of the coarse spodumene concentrate (-6 +2 mm TBE Sinks) for NAGROM using x-ray diffraction (XRD) and scanning electron microscopy (SEM) using the modified SWeRF method.

Centre for Microscopy, Characterisation and Analysis (CMCA) used SEM/EDS analysis to determine respirable sized fibrous minerals in coarse spodumene concentrate and to speciate those fibres.

The below sections outline the air monitoring methods in more detail.

2.1 Asbestiform Fibres

Occupational airborne fibre monitoring was performed using asbestos cowls connected via Tygon tubing

to SKC AirChek or Gilian battery-powered pumps. The sampling trains were mounted in accordance with

Guidance Note on the Membrane Filter Method for Estimating Airborne Asbestos Fibres, 2nd Edition

[NOHSC:3003 (2005)]. The counting criteria was the WHO rather than the DMP criteria. The WHO criteria

are more conservative for protecting health than the DMP criteria.

2.2 Respirable dust

Occupational respirable dust air monitoring was performed using cyclone sampling heads connected via

Tygon tubing to SKC AirChek or Gillian battery-powered pumps. The cyclone sampling heads were

mounted in accordance with AS 2985-2009 Workplace atmospheres—Method for sampling and

gravimetric determination of respirable dust. Pump air flows were checked before and after sampling and

minimum sample volumes attained. Personal and static monitoring was conducted.

Analysis was carried out by a NATA accredited laboratory by gravimetric determination.

2.3 Crystalline silica

Once analysed by gravimetric determination, the filters from the respirable dust sampling underwent

further analysis at a NATA accredited laboratory whereby the presence of crystalline silica was

determined by Fourier Transform Infrared Spectrometry (FTIR) analysis.



It must be noted that whilst the assessment attempted to capture the conditions relating to work activities

at the time of sampling, environmental factors such as temperature, wind and humidity as well as natural

variation in workload, workflows and employee behaviour may have introduced some variability in the

results, if sampling were to be replicated.

3 LEGISLATION AND GUIDANCE

The Mines Safety and Inspection Regulations (MSIR) 1995, under the Mines Safety and Inspection Act,

are applicable to Western Australian Mines. Each responsible person at a mine must ensure that ‘a

suitable risk assessment is made of the consequences to the health of any person if exposed to

hazardous substances at the mine’.

Airborne concentrations of substances or mixtures have been compared to the exposure standards listed

in the Safe Work Australia on-line Hazardous Substances Information System at

http://hsis.safeworkaustralia.gov.au/ExposureStandards, if existing.

The exposure standards represent airborne concentrations of individual substances which, according to

current knowledge, should neither impair the health of, nor cause undue discomfort to, nearly all

employees. The exposure standards are not fine dividing lines between satisfactory and unsatisfactory

working conditions, but rather should be used to assess the quality of the working environment and

indicate where appropriate control measures are required.

3.1 Time Weighted Average Exposure Standards

The bulk of exposure standards are stated as a Time Weighted Average (TWA) concentration of the

substance over the duration of an eight hour working day, for a five day working week, for an entire

working life. During this eight hour averaging period, excursions above the TWA are permitted provided

the excursions are offset by an equivalent excursion below the standard throughout the working day.

An adjustment is required if the work day extends an eight hour day. The majority of workers, including

BSOs and electricians, work a 4 x 4 days for 12 hours and a small group works a 5 x 2 day, 8 hour roster.

The Brief and Scala model has been used to adjust the exposure standards. The Brief and Scala is the

most conservative model.

Trigger levels are established to trigger an investigation and /or remedial actions at a fraction of the

respective exposure standard. It is generally considered good occupational health practice to apply an

action level at 50% of the relevant exposure standard.



3.2 Exposure Standards

The following exposure standards are relevant to the assessment.

Exposure standards listed in the Table 1 are based on the document Adopted National Exposure

Standards for Atmospheric Contaminants in the Occupational Environment [NOHSC: 1003(1995)] and

subsequent amendments.

4 POTENTIAL HEALTH IMPACTS

Health risks posed by inhaled dust particles are influenced by both the penetration and deposition of

particles in the various regions of the respiratory tract and the biological responses to these deposited

materials. Biosolubility is also a factor.

Particle size is the primary determinant of the depth to which particles can penetrate the human

respiratory tract. Since smaller particles are able to penetrate further into the lungs than larger particles,

they are generally of more concern from a health perspective. It is the respirable size particles that can

travel further, into the lung’s unciliated airways and become lodged in the alveolar region. The health

implications of this are more pronounced than is the case for particles lodged higher in the ciliated regions

of the respiratory tract.

Exposure to multiple air contaminants should also be considered as respirable dust, respirable silica, and

fibres are all chemical hazards with additive action that can adversely impact the respiratory tract, though

impacting in different ways.

The exposure index is a method recommended by Safe Work Australia for dealing with exposures to

mixtures of chemicals. The exposure index is calculated by adding the ratios of each exposure to the

exposure standard as follows:

Exposure index = C1 + C2 + C3 +…+ Cn ES1 ES2 ES3 ESn

Where C = measured concentration

ES = exposure standard

N = number of measurement

If the calculated exposure standard is less than one, then the exposure standard is deemed to be

acceptable. According to Safe Work Australia, this method is applicable when the components of the



mixture are acting on the same target organ and the effects are believed to be additive (i.e. not synergistic,

independent or antagonistic). Smoking and diesel particulates could be other potential contributing

hazardous factors affecting the lung, though they affect the lung in different ways.

For example, if the electrician has a measurement of fibres 0.01 f/mL, respirable dust of 0.3 mg/m3 and

respirable silica 0.04 mg/m3, the exposure index would be:

Exposure index = 0.01 + 0.25 + 0.04 0.1 3.0 0.10

Exposure Standard = 0.1 + 0.08 + 0.4 = 0.058, which is < 1.

The calculated exposure standard is less than one, therefore potential for adverse health impacts to occur

is unlikely.

4.1 Fibres

Fibrous materials can be a hazard if airborne fibres of respirable size are inhaled into the body. The harm from airborne asbestiform fibres is not immediately obvious because the fibres are not visible. There is often a very long period between exposure and the onset of disease (known as latency). The inhalation of asbestiform mineral fibres can be associated with three serious and often fatal diseases – mesothelioma, asbestosis and lung cancer. Specifically, asbestiform mineral fibres affect the pleural membranes. Persons are more likely to experience asbestiform mineral-related disease after exposures for a long period of time (chronic exposure).

4.2 Respirable Dust

Respirable dust can reach the deepest part of the lungs, the alveoli, thereby compromising functioning of

a healthy lung. It has been linked to bronchitis, chronic obstructive pulmonary disease and emphysema.

4.3 Respirable Silica

All forms of respirable silica have the potential to cause silicosis, an irreversible and progressive condition

in which a healthy lung becomes replaced with areas of fibrosis. It may also be a contributor to lung

cancer. It has also been associated with chronic obstructive pulmonary disease.

5 RISK ASSESSMENT

Risk assessment is the overall process of risk identification, risk analysis and risk evaluation.

5.1 Risk Identification

The source of potential risk to employee health is limited to the coarse spodumene concentrate product. The spodumene was delivered to the Kwinana Bulk Terminal (KBT) by trucks (Photograph 1) and stockpiled (Photograph 2) adjacent to the workshop at the Kwinana Bulk Terminal, before being loaded onto the ship commencing 5 February 2017 (Photograph 3). The coarse spodumene concentrate was the first of its kind to be stockpiled and loaded at Kwinana Bulk Terminal (KBT) in December 2016 and further product is expected on site in the future. Dust has the potential to accumulate on surrounding infrastructure and mobile plant.



The prevailing wind direction was a southerly with an approximate speed of 20 km/hr. The weather was fair during the days that the air surrounding the stockpile was monitored. No dust suppression system was operating during loading, other than pre-conditioning with water. The primary areas of impact at KBT of spodumene are for persons working in the vicinity of the stockpiles, conveyors and shiploader. Generally, movement or handling of the spodumene will grind the material creating finer particles, thereby increasing the risk of materials to become of respirable size and airborne. The mica is visible across site and it is possible that mica may be blown into the sea and wash up at Rockingham or Naval Base. Analytical results are provided in Appendix A.

5.1.1 Bulk Coarse Spodumene Concentrate Sampling

The total silica and quartz contents of coarse spodumene concentrate was analysed.

Silica (as total silica SiO2, not quartz) was identified as the predominant minerals within the ore sample

at 66% by weight and consisted of the following minerals:

Spodumene (Li Al Si2O6) Quartz (SiO2)

K-Feldspar (KAlSi3O8)

Clinochlore Mg5 Al( Si, Al)4 O10 (OH)8

Albite, ordered (Na Al Si3O8)

Muscovite ((K ,Na ) (Al, Mg, Fe)2 ( Si3.1 Al0.9 ) O10 (OH)2)

Actinolite Ca2 (Mg, Fe+2)5 Si8 O22(OH)2

Microcline (K0.964 Na0.036 Al Si3 O8)

The quartz content was found to be about 12% by weight. This was the total quartz content i.e. not respirable size composition. Respirable Quartz was determined by combining the information in the Microanalysis report Size Fraction and Mineral Phase Tables. The concentration of Quartz in the Mineral Phase was identified at approximately 10% by weight and the percentage of respirable material (PM4) was provided as 0.51% by volume, which equates to approximately 0.05% by volume respirable quartz.

Depending on the origin and blending of the coarse spodumene concentrate, there can be variable quartz.

The quartz is likely to be between 5-15% by weight. The quartz within the product is in large crystals and

therefore poses a low risk to health. However, if this material is ground in some way, it will generate

respirable quartz and become a hazard.

MicroAnalysis Australia analysed a sample (15_1489_2) of the coarse spodumene concentrate (-6+2 mm

TBE Sinks) for NAGROM for the respirable alpha-quartz concentration. The concentration of muscovite

was about 18% (weight) and quartz 10% (weight). The respirable crystalline silica concentrations for

alpha quartz was 0.004% of bulk material; and cristobalite and tridymite were both <0.001% of bulk

material.

Coarse spodumene concentrate samples were taken from the stockpile to determine the amphibole

fibrous minerals and quartz content in the respirable size. This was analysed by SEM/EDS by the CMCA.

Spodumene, quartz, chlorite, feldspars, actinolite and hornblende were detected in the respirable size.

(Hornblende is a precursor to amphiboles). Amphiboles are a group of minerals that are normally from

an ultramafic or mafic source and can form asbestiform minerals (excluding chrysotile) if the right

geological conditions apply .



The concentration of respirable fibrous minerals observed in the coarse spodumene concentrates was

low.

5.1.2 Airborne Fibre Monitoring

Control airborne fibre monitoring was undertaken surrounding the coarse spodumene concentrate, in the

tunnel during shiploading and in the cabins of the front end loader and shiploader.

All airborne fibre monitoring results were less than or equal to 0.01 f/mL (Limit of Detection), therefore

well below the occupational exposure standard of 0.1 f/mL.

The membrane filter method used does not distinguish between different types of fibres, including

synthetic mineral fibres and organic fibres. To confirm the speciation of the fibres, SEM / EDS analysis is

required.

5.1.3 Respirable Dust and Silica Monitoring Results

Respirable dust and respirable silica were monitored personally on the loader operator, Bulk Services

Officer (BSO), fitter and electrician.

The highest respirable dust result was 0.3 mg/m3 (electrician) and the rest were below 0.1 mg/m3, which

is well below the national exposure standard of 3.0 mg/m3.

The highest respirable quartz result was 0.04 mg/m3 (electrician) and the rest were below

0.01 mg/m3 which is well below the national exposure standard of 0.1 mg/m3.

Respirable dust and respirable quartz were monitored statically surrounding the stockpile, north, south,

east and west and in the cabins of the front end loader and shiploader.

The highest static respirable dust result was 0.2 mg/m3 (outside Front End Loader) and the rest were

≤0.1 mg/m3.

The static respirable quartz sample results were below 0.005 mg/m3.

5.2 Risk Analysis

The following factors were considered to determine the level of risk:

The coarse spodumene product is wet sieved before delivery to KBT. This practice should

remove the vast majority of respirable dust.

Some fugitive dust was observed during gusts of wind. The results from the air monitoring during

this time indicate fibres, respirable dust and respirable silica levels were all well below the

applicable exposure standards.

The concentration of respirable fibrous minerals observed in the coarse spodumene concentrates

by SEM/EDS analysis was low.

The quartz within the product is in large crystals and therefore poses a low risk to health. If this

material is ground in some way, it will generate respirable quartz and become a hazard.

The composition of the concentrate is unlikely to change when different depths and pits are mined

because the concentrate is processed through a concentrator.



Fibres are hazardous if they are airborne and respirable in size. All fibre monitoring results were

well below the national exposure standard of 0.1 f/mL.

Personal respirable dust monitoring results were below the trigger level and national exposure


Static respirable dust monitoring results were below the trigger level and national exposure

standard of 3.0 mg/m3..

Personal respirable quartz monitoring results were below national exposure standard of

0.1 mg/m3.

Static respirable quartz monitoring results were below the trigger level and national exposure


The calculated exposure index for the additive atmospheric contaminants of fibres, respirable

dust and respirable quartz was calculated to be less than one and therefore are unlikely to cause

harm.

The ARL lab report provided by FPA, tested whether it is environmentally hazardous material

and the results show that essentially all the minerals are highly insoluble in water. Therefor there

is no hazard from toxic metals.

If the controls outlined in this Section are continued / implemented, then airborne contaminant

concentrations are likely to be low and the risk of exposure low.

Controls should be reviewed for their effectiveness.

The risk of exposure to respirable size asbestiform fibres and respirable quartz could increase over time,

however, if dust from the coarse spodumene concentrate accumulates with future product handling on

site this may increase, especially in regards to people doing maintenance on conveyors etc. . The fibres

and quartz in settled dust will be ground into smaller particles and may increase in concentration if not

removed. It is therefore recommended that the dust is eliminated or minimised as much as possible to

minimise exposure to employees.

Occupations with the highest risk of exposure are those working in close vicinity and handling the coarse

spodumene concentrate. The tunnel is likely to be the dustiest area.

5.3 Risk Evaluation

It is considered that monitoring is necessary to determine whether there is a risk to health. To achieve

this, groups of workers having the same general exposure profile (similar exposure groups) should be

monitored, which will result in expected exposure profiles. A representative number (eg 6-8 samples)

should be monitored quarterly to establish a quantitative baseline. Generally, the greater the number of

samples taken, the greater the confidence there will be in the average result for an air contaminant. Each

worker is recommended to be classed into similar exposure groups based on work activities and work

shift lengths. Each SEG can then be statistically analysed to determine whether air contaminant levels

are acceptable, unacceptable or uncertain.

Once the expected exposure profiles have been determined, the data will enable control strategies to be

implemented where necessary. This data will help establish the level of control required which will be

based on the hierarchy of controls, including elimination, substitution, isolation, engineering,

administration and PPE, to help reduce exposure to air contaminants to as low as reasonably practical.

The data also assists in prioritising the risks.

Occupational air monitoring was conducted to determine airborne concentrations of fibres, respirable dust

and respirable silica in the workplace. This monitoring data together with observations, analytical data

and communications was used to assess the risk to health.

The risk from the spodumene is deemed to be low and acceptable mainly because the air monitoring

results indicate atmospheric contamiant levels are below the exposure standard and trigger level. If future

air monitoring of respirable quartz and fibres indicated exposure levels above the trigger levels provided

in Table 1, then action should be taken. Action may include reviewing the effectiveness of current

controls and implementing further controls if necessary to reduce exposure to below trigger levels.

All atmospheric contaminants measured (fibres and respirable dust/quartz) were below the exposure

standards and trigger levels.

Table 4. Level of Risk

Atmospheric Contaminant Level Level of Risk

Above the exposure standard Unacceptable (High)

Below the exposure standard but above the trigger level Medium (Action recommended)

Below the exposure standard and the trigger level Acceptable (Low)

The occupation with the highest risk was the electrician (Maintenance SEG). Areas with less natural or

mechanical ventilation, such as the tunnel, are likely to be the dustiest. Air monitoring is advised during

handling of the product to ensure the effectiveness of controls.



5.4 Risk Control

Controls for consideration that may eliminate and/or minimise air contaminant levels in the workplace

include:

5.4.1 Engineering Controls

Stockpiles to be kept moist such as sprinkler system. This is also to reduce visible mica and to

reduce the risk of mica reaching the sea.

The concentrate to be conditioned by water before loading commences (if not wet from a

sprinkler)

Positive pressure and HEPA filters installed into heavy vehicles

Keep cabin windows and doors closed

5.4.2 Administrative Controls

Implement and maintain a schedule for HEPA filter replacement and positive pressure checks

for heavy vehicles

Decontamination of the spodumene transport pathways - conveyors, transfer stations and ship

loader cabin. This is also to reduce visible mica and reduce the risk of mica reaching the sea.

Decontamination of dust from Front End Loader and Ship Loader cabins

Air monitoring for fibres and respirable quartz when spodumene concentrate is handled/moved

It is recommended that any fibre count above 10 fibres/100 fields be confirmed by SEM/EDS

analysis to determine if the fibre is asbestiform

Receiving analytical results for fibres and quartz content from Mount Marion mine products

coming to KBT if available

Another risk assessment is required for different products, such as fine spodumene concentrates.

A Fibrous Management Plan is recommended.

Even though the coarse spodumene concentrate has not been deemed to be a hazardous

substance, that a Safety Data Sheet of each lithium ore product is readily accessible to all

employees potentially affected

Record a reference to this risk assessment into the Ventilation Log Book by the appointed

Ventilation Officer as per Regulation 9.7.

5.4.3 Personal Protective Eqipment (PPE)

The tunnel has less ventilation and typically has higher dust concentrations. Therefore a higher

concentration of respirable fibres may occur in this area. P2 dust masks are currently worn and

this practice should continue.



Mica (muscovite) is a shiny mineral that can be used as an indicator of the spread of spodumene

dust. Mica is considered to be a low health hazard, however, eye protection, such as goggles, is

recommended as it is abrasive. The mica contamination may increase over time. The

aerodynamics of the platy mica means it can travel significant distances.

SAMPLED BY: As-received REPORT DATE: 16 December 2016

PROCEDURE The samples were lightly pulverized, then analyzed by X-ray diffraction to determine the minerals present. Quartz was detected and its content determined by XRD measurements of the sample and of a pure quartz standard. No correction was applied for the X-ray absorbency of the samples, which were considered to be similar to that of quartz.

RESULTS Although the abundances of the other minerals (spodumene, albite, K-feldspar, muscovite, amphibole and chlorite) appear to vary from sample to sample, the quartz contents are very similar

Client: NAGROMJob number: 15_1489Date: 11/01/2016Analysis: Respirable alpha-quartz concentration analysis by x-ray diffraction (XRD) and scanning

electron microscopy (SEM) using the modified SWeRF method

Sample PreparationThe sample was supplied to Microanalysis Australia as a particulates in a plastic bag.

A representative sub-sample was wet sieved at 2 mm, 1 mm and 500 µm, and the < 500 µm fraction(suspension) was thoroughly homogenized and sized by laser diffraction reporting size between 500 µm and20 nm.

The respirable fraction was abstracted from the < 500 µm suspension by settling and decantation, and theabstracted particle size, composition and morphology was verified by scanning electron microscope (SEM) forequivalent aerodynamic diameter (EAD).

Once the equivalent aerodynamic size was verified, the abstracted fraction was analysed qualitatively andquantitatively by x-ray diffraction to assess the alpha-quartz concentration.

AnalysisThe wet sieving was conducted using a light-flow (approximately 1 L /min) water spray jet on a nested stack ofstainless steel Endecotts sieves at 2 mm, 1 mm and 500 µm. The < 500 µm fraction was collected in a 25L

bucket. Each size fraction was oven dried at 105 °C. The dried weights of each of the fractions were noted andthe fraction percentage calculated based on the original dried starting weight.

The laser diffraction size distribution analyses were conducted using a Malvern Mastersizer MS2000 calibratedusing QAS3002 certified reference material and certified within specification. The analyses were conductedfollowing ISO13320-1:1999.

For the sedimentation, the time for a specific fall height for PM4 (EAD) particles was calculated using StokesLaw. The samples were then homogenised and allowed to settle for the calculated time before the

supernatant was decanted off, down to the limit of the fall height. The density and viscosity of water at 21 °C,and an assumed particle density were used.

The electron microscope used was a Carl Zeiss EVO50 equipped with an Oxford Instruments INCA energydispersive spectrometer (EDS). All images were acquired using backscatter electrons, unless otherwisespecified to highlight particle composition. The contrast in backscatter electron images is proportional toaverage elemental composition i.e. the brighter the particle the higher the atomic number. Some images withcontrasting brightness particles were examined by EDS for elemental composition.

The extracted fraction was deposited on a filter membrane for XRD analysis. A calibration suite of knownalpha-quartz content, PM4 sized alpha-quartz particulate, loaded membranes were used as a calibration seriesagainst which the abstracted respirable fines on the filter membranes from the processed sample werecompared. Additional scan time was undertaken to achieve better signal to noise ratios in the spectrum.Quantification was by the peak area integration method. Only crystalline material present in the sample willgive peaks in the XRD scan. Amorphous (non crystalline) material will add to the background. The search

match software used was EVA (Bruker). The ICDD card set was ICDD PDF4/Minerals 2014. The x-ray source wascobalt radiation. ICCD match probabilities are reported as an indication of how well the diffraction peaks ofthis sample compare with currently published literature on the quoted mineral. No Rietveld refinement wasconducted on the acquired spectrum unless otherwise stated.

The respirable quartz concentration of the bulk was calculated by multiplying the volume percent of therespirable-only fraction by the alpha-quartz concentration of the respirable only fraction.

SummaryThe size distribution of the sample by wet sieving and laser diffraction is shown below:

DUST-004 Airborne samples analysed according to AS 2985 for Respirable Dust or AS 3640 for Inhalable Dust . Sample

results based on volume data supplied by client. Samples tested as received, *accreditation does not cover

sampling.

DUST-004 Respirable Quartz determined after ashing, redeposition and FTIR determination.

The Quartz exposure standard is 100µg/m3, therefore where sampling follows MDHS 101 guidelines and at

least 500L of air is sampled, this is equivalent to a dust weight of 50µg/filter. The estimated measurement

uncertainty for the laboratory analysis of Quartz is 40% at 50µg at 95% confidence limit (i.e. statistically the

true value lies between 30-70µg / filter (60 – 140µg/m3) at 95% confidence). The estimated measurement

uncertainty was determined during method validation.
