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.
Report – Coarse Spodumene Concentrate Risk Asessment

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.

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
Report – Coarse Spodumene Concentrate Risk Asessment
21 February 2017 754-ENAUPERT04930AA – Fremantle Port Authority – Coarse Spodumene Concentrate Risk Assessment 6
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.
Report – Coarse Spodumene Concentrate Risk Asessment
21 February 2017 754-ENAUPERT04930AA – Fremantle Port Authority – Coarse Spodumene Concentrate Risk Assessment 7
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 .
Report – Coarse Spodumene Concentrate Risk Asessment
21 February 2017 754-ENAUPERT04930AA – Fremantle Port Authority – Coarse Spodumene Concentrate Risk Assessment 8
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.
Report – Coarse Spodumene Concentrate Risk Asessment
21 February 2017 754-ENAUPERT04930AA – Fremantle Port Authority – Coarse Spodumene Concentrate Risk Assessment 9
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
standard of 3.0 mg/m3.
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
standard of 0.1 mg/m3.
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

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.
Report – Coarse Spodumene Concentrate Risk Asessment
21 February 2017 754-ENAUPERT04930AA – Fremantle Port Authority – Coarse Spodumene Concentrate Risk Assessment 13
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.

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
Suite 6642 Albany Hwy

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:

Method ID Methodology Summary
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.
