3. Introduction RCMA Australia Pty Ltd (RCMA) proposes to drill the Cervantes 1 exploration well, 11 km south of Dongara/Port Denison in Production Licence L14 (Figure 1). The proposed site is located within the vegetated Beekeepers Nature Reserve (BKNR) in the northern Perth Basin (Figure 2). The proposed well will be deviated to avoid environmental sensitivities and will be drilled to a planned depth of 2,562 mTVD (true vertical depth). The well pad will occupy an area of approximately 2.6 ha with 4.1 km of existing road and tracks utilised for access. Site preparation operations are planned to commence in early quarter 1 CY2022, with drilling operations commencing late quarter 1 CY2022. RCMA is an Australian upstream oil and gas company that own and operate the Jingemia Production Facility (JPF), an onshore Perth Basin oil production facility situated in Petroleum Production Licence L14, 3 km from the Cervantes 1 Conventional Oil Exploration Drill Site. A Cervantes 1 Development would utilise the existing JPF Facilities.

Page 8: Cervantes 1 Conventional Oil Exploration Well Environment ...

RCMA-02-EM-PLN-001SUMv5 PAGE | 8 of 17

4.2 Site Preparation Access will be provided via upgrades to existing tracks from the JPF along the railway easement track and existing railway crossing (Figure 2). The well pad will be located within the development envelope and will possibly be located in the southern end as per Figure 2. The well site will include the following elements: • Cellar for drilling rig • Flare pit • Residual drilling fluid and cuttings storage pond (sump) • Water holding pond (turkey nest) / water storage tanks • Shallow groundwater monitoring bore • Workshop area and office space • VSP pit • Smoko shack • Generator set and pump skid unit • Toilet block and sewage holding tank • Parking for light vehicles, trucks and trailers • Fuel and chemical storage areas.

The overall cleared area is approximately 2.6 ha. This includes the well site (2 ha) that will be compacted along with an external area to cater for soil stockpiling and a fire break around the perimeter. Measures will be in place to reduce impacts of the operation on native fauna: • Installing fauna egress matting within the ponds (mud sump and turkey’s nest) • Installing fencing to deter ground-dwelling native fauna accessing the mud sump, turkey’s

nest and VSP pit. Fencing will remain around the drilling sump and turkey nest and be erected around the wellhead following completion of drilling operations until the infrastructure is decommissioned.

4.3 Vehicle Movement The drilling rig, ancillary services, personnel and supplies will be mobilised by road to the project area. Access is via the JPF utilising the Brand Highway. Vehicle and equipment movement will be restricted to the designated access tracks. There will be approximately 70-80 trailer loads moved during mobilisation and demobilisation. A crew change bus will be used to move personnel between Perth and the project location for rotational crew changes and between the offsite accommodation and drill site for shift changes. Utilisation of shared vehicles and a crew change bus will minimise vehicle movement to and from the site as much as practicable, minimising local traffic and vehicle-related safety and environment risks.

4.4 Drilling Once the drill rig is assembled on location, all activities associated with drilling (e.g. refuelling, mixing of drilling muds and cement) occur on the well pad. The project involves the following key stages: • Drilling the well with a rotary drilling rig using recirculated WBM (primarily (>97%) water,

and non-toxic additives; barite, potassium chloride, calcium carbonate, sodium chloride and bentonite)

• Conducting wireline logging evaluation of the formations drilled • Cementing well steel casing strings in place

Page 9: Cervantes 1 Conventional Oil Exploration Well Environment ...

RCMA-02-EM-PLN-001SUMv5 PAGE | 9 of 17

• Plug and abandonment of the well (in a dry hole case) Rotary drilling is the process of utilising a drill string and drill bit to break small pieces of rock and remove these pieces of rock from the hole by circulating a fluid (drilling mud) down the drill string and up the annulus between the drill string and drilled hole. A blow out preventer (BOP) is installed once drilling is at a depth where it is possible for hydrocarbons to be intersected. The BOP (secondary well control) provides a mechanical means by which the well can be closed and secure the contents of the well should the mud system fail to maintain a positive pressure on the drilled hole. If hydrocarbons are intersected, and flow to surface is not prevented by the drilling mud, the BOP will be closed allowing a controlled release of these hydrocarbons to the flare pit. The flare pit and any firebreaks are constructed in compliance with any specific DFES permit requirements. All drilling fluids will be contained within the mud system. This system is constantly monitored by personnel and pit level sensors for volume changes. The chemicals proposed for use in the Cervantes 1 program are disclosed within Appendix A. The disclosure tables have been prepared in accordance with the guideline and the Chemical Disclosure Reporting template provided for within the guideline. The chemical disclosure tables cover the following ‘down-hole’ activities: • Drilling (WBMs) • Cementing

The Safety Data Sheets (SDSs) for the chemicals associated with the Cervantes 1 activities are provided in Appendix B.

4.5 Chemicals and Materials Storage, Handling and Transfers All chemicals and hazardous materials required for the project will be appropriately packaged and delivered to the rig site in tanks, pails or drums, sealed bags and where appropriate stacked and secured on pallets. All chemicals and hazardous materials will be transported as required by regulation according to the material class and associated specific transportation advice. All transported materials shall be accompanied by a current SDS. Oil, fuel, and hazardous liquid chemicals will be stored in the bunded chemical storage area on the well pad. All chemicals will be stored in accordance with the requirements of their relevant SDS. SDSs for each chemical used and stored onsite are held in the site office. On site oil, fuel, and hazardous liquid chemicals will be bunded to contain not less than 110% of the volume of the largest vessel and at least 25% of the total substance stored (where more than one storage is connected to a common compound, drainage tank or similar storage vessel)). This includes waste hydrocarbon products. Dry chemicals will be stored off the ground on pallets and covered with tarpaulins to maintain product integrity during wet conditions. Empty hazardous liquid chemical containers or drums will be stored within the waste storage area.

4.6 Well Testing If the Cervantes 1 well proves successful and further evaluation through well testing is required, the additional evaluation phases of the Cervantes 1 well operations would commence as soon as reasonably possible. These would be expected to continue over a period of 1 month during Q3 2022 with actual duration determined based on the acquired evaluation data. This would include operations such as wellbore clean out, completion installation, well test operations, production logging evaluation, and other associated well intervention activities as specified in the well completion and testing programme to complete this evaluation phase of the project.

4.7 Waste Management Waste will be segregated and stored within designated areas and disposed via an approved waste disposal contractor in accordance with Table 3. Waste receptacles will be clearly labelled and have

Page 10: Cervantes 1 Conventional Oil Exploration Well Environment ...

RCMA-02-EM-PLN-001SUMv5 PAGE | 10 of 17

adequate covering (noting that the steel recycling skip bin does not need to be covered). Records will be retained for all waste disposal events.

Rehabilitation planning has been undertaken in accordance with the DMIRS Guidance Note – Decommissioning, rehabilitation, and closure of petroleum activities [DMIRSNOV19_6259] and a site-specific rehabilitation plan has been developed based on appropriate objectives, standards and methods to ensure that all disturbed areas are decommissioned and rehabilitated within a specified timeframe and in an ecologically sustainable manner such that the post disturbance environment is commensurate with the ecological and landscape values of BKNR, avoiding any significant long-term detrimental risks, impacts and liabilities. The rehabilitation plan outlines the following aspects:

o Current Conditions and Issues o Risk Assessment o Earthworks and Site Preparation to be undertaken o Propagule Introduction and Fertilising o Closure and Specific Completion Criteria consistent with specific, measurable,

attainable, relevant, time-bound (SMART) criteria o Thresholds and Triggers o Responsibility and Accountability o Supervision & Schedule o Monitoring and Maintenance o Reporting and Review

The completion criteria and performance indicators included in the rehabilitation plan have been agreed by DBCA to ensure that rehabilitation achieves a stable and functioning landform and ecological system consistent with pre-existing and surrounding landscape and environmental values. DBCA and EPA have approved the Cervantes 1 Rehabilitation Plan. Rehabilitation will be monitored annually with inspections of the rehabilitating site undertaken monthly until completion criteria are achieved. The projected timeline for decommissioning and rehabilitation is presented in Table 4. It is projected in an unsuccessful drilling case that Cervantes 1 will achieve its completion criteria in 2026.

Acute Toxicity: LD50 (Ingestion): 1500 mg/kg (mouse) LD50 (Intraperitoneal): 620 mg/kg (mouse) LD50 (Intravenous): 117 mg/kg (mouse) LDLo(Ingestion): 20 mg/kg (man) LDLo (Intraperitoneal):900 mg/kg (guinea pig) LDLo (Intravenous): 77 mg/kg (guinea pig) LDLo (Subcutaneous): 2120 mg/kg (frog) TDLo(Ingestion): 60 mg/kg/days (woman) Ecotoxicty Data: In short-term acute toxicity tests with fish, daphnia and algae the following results were found (lowest test result values): Ictalurus punctulus 48h-LC50 = 720 mg/l; Daphnia magna: 48h-LC50 = 177 mg/l; Nitzschia linearis: 120 h-EC50 = 1337 mg/l. A chronic reproductive test with the invertebrate Daphnia magna gave a LOEC of 101 mg/l. All the studies compiled on the acute and chronic aquatic toxicity were > 100 mg/L. Thus it is concluded that KCl is not hazardous to freshwater organisms. Taking into considerations the background concentrations of KCl in seawater (380 mg/l K+ and 19,000 mg/l Cl-), it is concluded that there is no reason for further investigations of KCl on marine species. The low concern for the environment is supported by the absence of a bioaccumulation potential for the substance. Biodegradation/Bioaccumulation: Biodegradability does not pertain to inorganic substances. Does not bioaccumulate. Mobile in Soil: No impact if small amount is released to the soil.

Chronic Toxicity: Silicosis: Excessive inhalation of respirable crystalline silica dust may cause a progressive, disabling, and sometimes- fatal lung disease called silicosis. Symptoms include cough, shortness of breath, wheezing, non-specific chest illness, and reduced pulmonary function. Individuals with silicosis are predisposed to develop tuberculosis. Cancer Status: The International Agency for Research on Cancer (IARC) has determined that crystalline Yes silica inhaled in the form of quartz or cristobalite from occupational sources can cause lung cancer in humans (Group 1 - carcinogenic to humans) and has determined that there is sufficient evidence in experimental animals for the carcinogenicity of tridymite (Group 2A - possible carcinogen to humans). Biodegradation/bioaccumulation: Silica is a naturally occurring, insoluble component of soil. Biodegradation is "not applicable" for crystalline silica since it is inorganic. Concentration-based toxicity values were not available.

16. OTHER INFORMATION

RESPIRATORS: In general the use of respirators should be limited and engineering controlsemployed to avoid exposure. If respiratory equipment must be worn ensure correct respiratorselection and training is undertaken. Remember that some respirators may be extremelyuncomfortable when used for long periods. The use of air powered or air supplied respirators shouldbe considered where prolonged or repeated use is necessary.

EXPOSURE CONTROL: If utilised in a closed system the potential for over exposure is reduced. Ifnot used in a closed system, local exhaust ventilation is recommended to control exposure. Provideeye wash and safety shower in close proximity to points of potential exposure. Where the potentialfor an inhalation risk exists, an approved respirator may be required. Do not eat, store, consumefood, tobacco or drink in areas where product is used.

PERSONAL PROTECTIVE EQUIPMENT GUIDELINES:The recommendation for protective equipment contained within this report is provided as a guideonly. Factors such as form of product, method of application, working environment, quantity used,product concentration and the availability of engineering controls should be considered before finalselection of personal protective equipment is made.

4.3 Immediate medical attention and special treatment neededCORROSIVE POISONING TREATMENT: Immediate treatment preferably in a hospital is mandatory. In treating corrosive poisoning,DO NOT INDUCE VOMITING; DO NOT ATTEMPT GASTRIC LAVAGE; and DO NOT ATTEMPT TO NEUTRALISE THE CORROSIVESUBSTANCE. Vomiting will increase the severity of damage to the oesophagus as the corrosive substance will again come incontact with it. Attempting gastric lavage may result in perforating either the oesophagus or stomach. Immediately dilute the corrosivesubstance by having the patient drink milk or water. If the trachea has been damaged tracheostamy may be required. Foroesophageal burns begin broad-spectrum antibiotics and corticosteroid therapy. Intravenous fluids will be required if oesophageal orgastric damage prevents ingestion of liquids. Long-range therapy will be directed toward preventing or treating oesophageal scarsand strictures.

Over exposure may result in irritation of the nose and throat, with coughing. High level exposure may resultin breathing difficulties.

STOT - singleexposure

This product does not present an aspiration hazard.Aspiration

Not classified as causing organ damage from repeated exposure.STOT - repeatedexposure

Not classified as a reproductive toxin. Insufficient data available to classify as a reproductive toxin. Thesubstance is not expected to be systemically available in the body under normal handling and use conditionsand for this reason it can be stated that the substance will not reach the foetus nor reach male and femalereproductive organs. The substance is not expected to be systemically available in the body under normalhandling and use conditions and for this reason additional testing is considered unnecessary.

Reproductive

Not classified as a carcinogen. Insufficient data available to classify as a carcinogen. Systemiccarcinogenicity is not expected to occur because the substance is not expected to be systemically availablein the body under normal handling and use conditions.

Carcinogenicity

Insufficient data available to classify as a mutagen. Both the in vitro and the in vivo genetic toxicity testsindicated no evidence of mutagenic activity. Furthermore the substance is not expected to be systemicallyavailable in the body under normal handling and use conditions and for this reason additional testing isconsidered unnecessary (EU RAR, 2007).

11.1 Information on toxicological effects

12. ECOLOGICAL INFORMATION

12.1 Toxicity

EC50 Ceriodaphnia: 40 mg/L.

No other valid studies available. The hazard of NaOH for the environment is caused by the hydroxyl ion (pH effect). For this reason theeffect of NaOH on the organisms depends on the buffer capacity of the aquatic or terrestrial ecosystem (see also 3.1.2). Also thevariation in acute toxicity for aquatic organisms can be explained for a significant extent by the variation in buffer capacity of the testmedium. LC50 values ranged between 33 and 189 mg/L.

12.2 Persistence and degradabilityReadily biodegradable. NaOH is a strong alkaline substance that dissociates completely in water to Na+ and OH-. High watersolubility and low vapour pressure indicate that NaOH will be found predominantly in aquatic environment. This implies that it will notadsorb on particulate matter or surfaces. Atmospheric emissions as aerosols are rapidly neutralized by carbon dioxide and the saltswill be washed out by rain.

Revision No: 2.5ofPage 5 7

Page 106: Cervantes 1 Conventional Oil Exploration Well Environment ...

CAUSTIC SODAPRODUCT NAME

12.4 Mobility in soil

High water solubility and mobility

WATER: If released to waterways, alkaline products may change the pH of the waterway. Fish will die if the pH reaches 10-11(goldfish 10.9, bluegill 10.5). SOIL: May leach to groundwater with toxic effects on aquatic life as above. ATMOSPHERE: Notexpected to reside in the atmosphere. Drops or particles released to atmosphere should be removed by gravity and/or be rained out.

12.5 Other adverse effects

12.3 Bioaccumulative potentialDoes not bioaccumulate. Considering its high water solubility, NaOH is not expected to bioconcentrate in organisms. In addition,sodium is a naturally-occurring element that is prevalent in the environment and to which organisms are exposed regularly, for whichthey have some capacity to regulate the concentration in the organism.

13. DISPOSAL CONSIDERATIONS

Collect without generating dust. Place in clean, sealed containers and dispose of to an approved landfill site.Contact the manufacturer/supplier for additional information (if required). The product can be neutralisedusing highly diluted hydrochloric acid, which should be added very slowly by specialised personnel wearingproper protection. Never neutralise the solid product.

12. ECOLOGICAL INFORMATION

12.1 Toxicity

The high pH when undiluted or unneutralized is acutely harmful to aquatic life. The following data is reported for chemically similarSodium Silicates on a 100% solids basis: A 96 hour median tolerance for fish (Gambusia affnis) of 2320 ppm; a 96 hour mediantolerance for water fleas (Daphnia magna) of 247 ppm; a 96 hour median tolerance for snail eggs (Lymnea) of 632 ppm; and a 96 hourmedian tolerance for Amphipoda of 160 ppm.

12.2 Persistence and degradabilityThis material is not persistent in aquatic systems.

12.4 Mobility in soil

Expected to be mobile in soil. Diluted material rapidly depolymerizes to yield dissolved silica in a form that is indistinguishable fromnatural dissolved silica.

16. OTHER INFORMATION

EXPOSURE STANDARDS - TIME WEIGHTED AVERAGES: Exposure standards are established onthe premise of an 8 hour work period of normal intensity, under normal climatic conditions and wherea 16 hour break between shifts exists to enable the body to eliminate absorbed contaminants. In thefollowing circumstances, exposure standards must be reduced: Strenuous work conditions; hot,humid climates; high altitude conditions; extended shifts (which increase the exposure period andshorten the period of recuperation).

RESPIRATORS: In general the use of respirators should be limited and engineering controlsemployed to avoid exposure. If respiratory equipment must be worn ensure correct respiratorselection and training is undertaken. Remember that some respirators may be extremelyuncomfortable when used for long periods. The use of air powered or air supplied respirators shouldbe considered where prolonged or repeated use is necessary.

PERSONAL PROTECTIVE EQUIPMENT GUIDELINES:The recommendation for protective equipment contained within this report is provided as a guideonly. Factors such as form of product, method of application, working environment, quantity used,product concentration and the availability of engineering controls should be considered before finalselection of personal protective equipment is made.

HEALTH EFFECTS FROM EXPOSURE:It should be noted that the effects from exposure to this product will depend on several factorsincluding: form of product; frequency and duration of use; quantity used; effectiveness of controlmeasures; protective equipment used and method of application. Given that it is impractical toprepare a report which would encompass all possible scenarios, it is anticipated that users willassess the risks and apply control methods where appropriate.

16. OTHER INFORMATION

EXPOSURE STANDARDS - TIME WEIGHTED AVERAGES: Exposure standards are established onthe premise of an 8 hour work period of normal intensity, under normal climatic conditions and wherea 16 hour break between shifts exists to enable the body to eliminate absorbed contaminants. In thefollowing circumstances, exposure standards must be reduced: Strenuous work conditions; hot,humid climates; high altitude conditions; extended shifts (which increase the exposure period andshorten the period of recuperation).

COMBUSTIBLE - EXPLOSIVE CARBONACEOUS DUST: Carbonaceous/organic dusts have thepotential, with dispersion, to present an explosion hazard if an ignition source exists. All equipmentused to handle, transfer or store this product MUST BE cleaned thoroughly prior to cutting, welding,drilling or exposure to any other form of heat or ignition sources. If bulk stored, containers should beventilated on a routine basis to avoid vapour accumulation (where applicable, eg for flocculants).

PERSONAL PROTECTIVE EQUIPMENT GUIDELINES:The recommendation for protective equipment contained within this report is provided as a guideonly. Factors such as form of product, method of application, working environment, quantity used,product concentration and the availability of engineering controls should be considered before finalselection of personal protective equipment is made.

HEALTH EFFECTS FROM EXPOSURE:It should be noted that the effects from exposure to this product will depend on several factorsincluding: form of product; frequency and duration of use; quantity used; effectiveness of controlmeasures; protective equipment used and method of application. Given that it is impractical toprepare a report which would encompass all possible scenarios, it is anticipated that users willassess the risks and apply control methods where appropriate.

12. ECOLOGICAL INFORMATION

12.1 Toxicity

In short-term acute toxicity tests with fish, daphnia and algae the following results were found (lowest test result values): Ictaluruspunctulus 48h-LC50 = 720 mg/l; Daphnia magna: 48h-LC50 = 177 mg/l; Nitzschia linearis: 120 h-EC50 = 1337 mg/l. A chronicreproductive test with the invertebrate Daphnia magna gave a LOEC of 101 mg/l. All the studies compiled on the acute and chronicaquatic toxicity were > 100 mg/L. Thus it is concluded that KCl is not hazardous to freshwater organisms. Taking into considerationsthe background concentrations of KCl in seawater (380 mg/l K+ and 19,000 mg/l Cl-), it is concluded that there is no reason for furtherinvestigations of KCl on marine species. The low concern for the environment is supported by the absence of a bioaccumulationpotential for the substance.

12.2 Persistence and degradabilityBiodegradability does not pertain to inorganic substances.

12.4 Mobility in soil

No impact if small amount is released to the soil.

16. OTHER INFORMATION

RESPIRATORS: In general the use of respirators should be limited and engineering controlsemployed to avoid exposure. If respiratory equipment must be worn ensure correct respiratorselection and training is undertaken. Remember that some respirators may be extremelyuncomfortable when used for long periods. The use of air powered or air supplied respirators shouldbe considered where prolonged or repeated use is necessary.

WORKPLACE CONTROLS AND PRACTICES: Unless a less toxic chemical can be substituted for ahazardous substance, ENGINEERING CONTROLS are the most effective way of reducing exposure.The best protection is to enclose operations and/or provide local exhaust ventilation at the site ofchemical release. Isolating operations can also reduce exposure. Using respirators or protectiveequipment is less effective than the controls mentioned above, but is sometimes necessary.

PERSONAL PROTECTIVE EQUIPMENT GUIDELINES:The recommendation for protective equipment contained within this report is provided as a guideonly. Factors such as form of product, method of application, working environment, quantity used,product concentration and the availability of engineering controls should be considered before finalselection of personal protective equipment is made.

11. Toxicological Information

Information on routes of exposure Principle Route of Exposure Eye or skin contact, inhalation.

Symptoms related to exposure Most Important Symptoms/EffectsCauses severe eye irritation which may damage tissue. Causes skin irritation. May cause allergic skin reaction. Maycause respiratory irritation. Breathing crystalline silica can cause lung disease, including silicosis and lung cancer.Crystalline silica has also been associated with scleroderma and kidney disease.

Toxicology data for the components

Substances CAS Number LD50 Oral LD50 Dermal LC50 Inhalation

Portland cement 65997-15-1 > 2000 mg/kg (Rat) > 2000 mg/kg > 1 mg/L (Rat) 4h

Crystalline silica, quartz 14808-60-7 > 15000 mg/kg (human) No data available No data available

Immediate, delayed and chronic health effects from exposure Inhalation Causes moderate respiratory irritation. Inhaled crystalline silica in the form of quartz or

cristobalite from occupational sources is carcinogenic to humans (IARC, Group 1). There issufficient evidence in experimental animals for the carcinogenicity of tridymite (IARC, Group2A).

Breathing silica dust may cause irritation of the nose, throat, and respiratory passages.Breathing silica dust may not cause noticeable injury or illness even though permanent lungdamage may be occurring. Inhalation of dust may also have serious chronic health effects(See "Chronic Effects/Carcinogenicity" subsection below).

Eye Contact Causes severe eye irritation which may damage tissue.Skin Contact Causes skin irritation. May cause alkali burns with confined contact. May cause an allergic

skin reaction. Can dry skin.Ingestion Causes burns of the mouth, throat and stomach.

_____________________________________________________________________________________________CEMENT - CLASS G Revision Date: 02-Aug-2018

Chronic Effects/Carcinogenicity Silicosis: Excessive inhalation of respirable crystalline silica dust may cause aprogressive, disabling, and sometimes-fatal lung disease called silicosis.Symptoms include cough, shortness of breath, wheezing, non-specific chestillness, and reduced pulmonary function. This disease is exacerbated by smoking.Individuals with silicosis are predisposed to develop tuberculosis.

Cancer Status: The International Agency for Research on Cancer (IARC) hasdetermined that crystalline silica inhaled in the form of quartz or cristobalite fromoccupational sources can cause lung cancer in humans (Group 1 - carcinogenic tohumans) and has determined that there is sufficient evidence in experimentalanimals for the carcinogenicity of tridymite (Group 2A - possible carcinogen tohumans). Refer to IARC Monograph 68, Silica, Some Silicates and Organic Fibres(June 1997) in conjunction with the use of these minerals. The National ToxicologyProgram classifies respirable crystalline silica as "Known to be a humancarcinogen". Refer to the 9th Report on Carcinogens (2000). The AmericanConference of Governmental Industrial Hygienists (ACGIH) classifies crystallinesilica, quartz, as a suspected human carcinogen (A2). There is some evidencethat breathing respirable crystalline silica or the disease silicosis is associated withan increased incidence of significant disease endpoints such as scleroderma (animmune system disorder manifested by scarring of the lungs, skin, and otherinternal organs) and kidney disease.

11. Toxicological Information

Information on routes of exposure Principle Route of Exposure Eye or skin contact, inhalation.

Symptoms related to exposure Most Important Symptoms/EffectsBreathing crystalline silica can cause lung disease, including silicosis and lung cancer. Crystalline silica has alsobeen associated with scleroderma and kidney disease.

Toxicology data for the components

Substances CAS Number LD50 Oral LD50 Dermal LC50 Inhalation

Crystalline silica, quartz 14808-60-7 > 15000 mg/kg (human) No data available No data available

Immediate, delayed and chronic health effects from exposure Inhalation Inhaled crystalline silica in the form of quartz or cristobalite from occupational sources is

carcinogenic to humans (IARC, Group 1). There is sufficient evidence in experimentalanimals for the carcinogenicity of tridymite (IARC, Group 2A).

Breathing silica dust may cause irritation of the nose, throat, and respiratory passages.Breathing silica dust may not cause noticeable injury or illness even though permanent lungdamage may be occurring. Inhalation of dust may also have serious chronic health effects(See "Chronic Effects/Carcinogenicity" subsection below).

Eye Contact May cause mechanical irritation to eye.Skin Contact None known.Ingestion None known.

Chronic Effects/Carcinogenicity Silicosis: Excessive inhalation of respirable crystalline silica dust may cause aprogressive, disabling, and sometimes-fatal lung disease called silicosis.Symptoms include cough, shortness of breath, wheezing, non-specific chestillness, and reduced pulmonary function. This disease is exacerbated by smoking.Individuals with silicosis are predisposed to develop tuberculosis.

Cancer Status: The International Agency for Research on Cancer (IARC) hasdetermined that crystalline silica inhaled in the form of quartz or cristobalite fromoccupational sources can cause lung cancer in humans (Group 1 - carcinogenic tohumans) and has determined that there is sufficient evidence in experimentalanimals for the carcinogenicity of tridymite (Group 2A - possible carcinogen tohumans). Refer to IARC Monograph 68, Silica, Some Silicates and Organic Fibres(June 1997) in conjunction with the use of these minerals. The National ToxicologyProgram classifies respirable crystalline silica as "Known to be a humancarcinogen". Refer to the 9th Report on Carcinogens (2000). The AmericanConference of Governmental Industrial Hygienists (ACGIH) classifies crystallinesilica, quartz, as a suspected human carcinogen (A2). There is some evidencethat breathing respirable crystalline silica or the disease silicosis is associated withan increased incidence of significant disease endpoints such as scleroderma (animmune system disorder manifested by scarring of the lungs, skin, and otherinternal organs) and kidney disease.

Exposure LevelsNo data available

Interactive effects Individuals with respiratory disease, including but not limited to asthma and bronchitis, or subject to eye irritation, should not beexposed to quartz dust.
