### 11. TOXICOLOGICAL INFORMATION Principle Route of Exposure Eye or skin contact, inhalation. Inhalation May cause allergic respirator y reaction. 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 experim ental animals 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 lung damage may be occurring. Inhalation of dust may also have serious chronic health effects (See "Chr onic Effects/Carcinogenicity" subsection below).

Skin Contact None known. Eye Contact May cause mechanical irritation to eye. Ingestion None known Aggravated Medical Conditions Individuals with respiratory disease, including but not limited to asthma and bronchitis, or subject to eye irritation, should not be exposed to quartz dust. Chronic Effects/Carcinogenicity Silicosis: Excessive inhalation of resp irable crystalline silica dust may cause a progressive, disabling, and sometimes-fatal lung disease called silicosis. Symptoms include cough, shortness of breath, w heezing, non-specific chest illness, and reduced pulmonary function. This disease is exacerbated by smoking. Individuals with silicosis are predisposed to develop tuberculosis. Cancer Status: The International A gency for Research on Cancer (IARC) has determined that crystalline silica inhaled in the form of quartz or cristobalite from occupational sources can cause lung canc er in humans (Group 1 - carcinogenic to humans) and has determined that there is sufficient evidence in experimental animals for the carcinogenicity of trid ymite (Group 2A - possible carcinogen to humans). Refer to IARC Monograph 68, Silica, Some Silicates and Organic Fibres (June 1997) in conjunction with the use of these minerals. The National Toxicology Program classifies respirable crystalline silica as "Known to be a human carcinogen". Refer to the 9th Report on Carcinogens (2000). The American Conference of Governmental Industrial Hygienists (ACGIH) classifies crystalline silica, quartz, as a suspected human carcinogen (A2). There is some evidence that breathing re spirable crystalline silica or the disease silicosis is associated with an increased incidence of significant disease endpoints such as scleroderma (an immune system disorder manifested by scarring of the lungs, skin, and other internal organs) and kidney disease.

### 11. TOXICOLOGICAL INFORMATION Principle Route of Exposure Eye or skin contact, inhalation. Inhalation May cause allergic respirator y reaction. 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 experim ental animals 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 lung damage may be occurring. Inhalation of dust may also have serious chronic health effects (See "Chr onic Effects/Carcinogenicity" subsection below).

Skin Contact May cause skin irritation. May cause an allergic skin reaction. Eye Contact May cause eye irritation. Ingestion Causes burns of the mouth, throat and stomach. Aggravated Medical Conditions Individuals with respiratory disease, including but not limited to asthma and bronchitis, or subject to eye irritation, should not be exposed to quartz dust. Chronic Effects/Carcinogenicity Silicosis: Excessive inhalation of resp irable crystalline silica dust may cause a progressive, disabling, and sometimes-fatal lung disease called silicosis. Symptoms include cough, shortness of breath, w heezing, non-specific chest illness, and reduced pulmonary function. This disease is exacerbated by smoking. Individuals with silicosis are predisposed to develop tuberculosis. Cancer Status: The International A gency for Research on Cancer (IARC) has determined that crystalline silica inhaled in the form of quartz or cristobalite from occupational sources can cause lung canc er in humans (Group 1 - carcinogenic to humans) and has determined that there is sufficient evidence in experimental animals for the carcinogenicity of trid ymite (Group 2A - possible carcinogen to humans). Refer to IARC Monograph 68, Silica, Some Silicates and Organic Fibres (June 1997) in conjunction with the use of these minerals. The National Toxicology Program classifies respirable crystalline silica as "Known to be a human carcinogen". Refer to the 9th Report on Carcinogens (2000). The American Conference of Governmental Industrial Hygienists (ACGIH) classifies crystalline silica, quartz, as a suspected human carcinogen (A2). There is some evidence that breathing re spirable crystalline silica or the disease silicosis is associated with an increased incidence of significant disease endpoints such as scleroderma (an immune system disorder manifested by scarring of the lungs, skin, and other internal organs) and kidney disease.

### 3.2 Potential Health Effects Immediate Hazards

INGESTION: Not expected to be harmful under normal conditions of use. INHALATION: Not expected to be harmful unde r normal conditions of use. However, if allowed to become airborne, may cause irritation of nose, throat and lungs. SKIN: May cause irritation on prolonged or repeated contact. EYES: May cause irritation on prolonged or repeated contact. 

### Delayed Hazards
14808-60-7 Quartz (SiO2) CANCER HAZARD. Can cause cancer. Use of this product may generate silica dust (which may be invisible). Inhaled silica has been cla ssified by IARC as a human carcinogen. Inhalation of silica dust may cause delayed lung inju ry or lung fibrosis (including silicosis and/or pneumoconiosis) and/or other diseases which may lead to permanent disability and/or death. Silicosis is a form of disabling pulmonary fibrosis which can be progressive. Prolonged exposure to respirable silica may cause diminished lung capacity with shortnes s of breath during physical exertion and may cause fatigue, breathlessness, wheezing, cough, and sputum production. Pre-existing respiratory disorders may be aggravated by exposure. Smoking may aggravate th e effects of exposure and may increase the risk of developing respiratory disease from exposure. Consult with your employer and your doctor for further information or if you believe you may be developing any breathing or lung problems. There is some evidence that breathing respirable crystalline silica or the disease silicosis is associated with an increased incidence of significant disease endpoints such as scleroderma (an immune system disorder manifested by fibrosis of the lungs, skin and other internal organs) and kidney disease. Silicosis is also reported to increase the risk of tuberculosis.


## 4. First Aid Measures INGESTION: If accidentally swallowed, dilute by drinking large quantities of water. Immediately contact poison control center or hospital emergency room for any other additional treatment directions. INHALATION: Remove to fresh air. SKIN: In case of irritation, flush with water. EYES: Immediately flush eyes with plenty of water. Call a physician if irritation persists. 

## 5. Fire Fighting Measures Flash point Non-flammable Lower explosion limit Not applicable Upper explosion limit Not applicable Autoignition temperature Not applicable Will not burn. In case of fire, water should be used to keep fire-exposed containers cool.

### 7.2 Storage Do not expose to direct sunlight for long periods of time. Keep away from moisture. Store below 80 F out of direct sunlight in dry location. Keep away from heat. Store in cool, dry place to avoid blocking. Use with adequate ventilation. 

## 8. Exposure Controls/Personal Protection 8.1 Exposure Controls Avoid creating dust. If airborne contaminants are generated when the material is heated, handled, or transported, appropriate administrative and engineering controls, including sufficient ventilation in volume and air flow patterns, should be provided to keep air contaminant concentration levels below acceptable criteria. Minimize the collection (build-up) of dust on walls, floors, sills, ledges, machinery, or equipment. Work clothes should be changed daily and washed to prevent dust contact. These techniques may not necessarily address all issues pertaining to your operation. We, therefore, recommend that you consult with experts of your choice to determine whether or not your programs are adequate. Consult OSHA, state/provincial and local laws, and regulations. Review ASTM E 1132-99, "Standard Practice for Health Requirements Relating to Occupational Exposure to Respirable Crystalline Silica," as well as other guidelines such as NIOSH publications. 

### 8.2 Personal Protection Where air contaminants can exceed acceptable criteria, use NIOSH/MSHA approved respiratory protection equipment. Respirators should be selected based on the form and concentration of contaminants in air in accordance with OSHA laws and regulations or other applicable standards or guidelines, including ANSI standards regarding respiratory protection. Wear impervious gloves as required to prevent skin contact. Wear safety glasses with sideshields at all times to prevent eye irritation.

SKIN: May cause irritation on prolonged or repeated contact. EYES: May cause irritation on prolonged or repeated contact.
Note: Product has potential to release formaldehyde vapor during core/mold making and from decomposition during metal pouring. The amount and level will depend on local conditions of use. Formaldehyde gas is irritating to the eyes and upper respiratory tract and may aggravate existing respiratory conditions or allergies. OSHA has listed formaldehyde as a potential human carcinogen. See the OSHA formaldehyde standard 29 CFR 1910.1048 for further details. Product contains traces of hexamethylenetetramine which may cause allergic skin and respiratory reactions. 

### Delayed Hazards Quartz (SiO2) 14808-60-7 CANCER HAZARD. Can cause cancer. Use of this product may generate silica dust (which may be invisible). Inhaled silica has been classified by IARC as a human carcinogen. Inhalation of silica dust may cause delayed lung injury or lung fibrosis (including silicosis and/or pneumoconiosis) and/or other diseases which may lead to permanent disability and/or death. Silicosis is a form of disabling pulmonary fibrosis which can be progressive. Prolonged exposure to respirable silica may cause diminished lung capacity with shortness of breath during physical exertion and may cause fatigue, breathlessness, wheezing, cough, and sputum production. Pre-existing respiratory disorders may be aggravated by exposure. Smoking may aggravate the effects of exposure and may increase the risk of developing respiratory disease from exposure. Consult with your employer and your doctor for further information or if you believe you may be developing any breathing or lung problems. There is some evidence that breathing respirable crystalline silica or the disease silicosis is associated with an increased incidence of significant disease endpoints such as scleroderma (an immune system disorder manifested by fibrosis of the lungs, skin and other internal organs) and kidney disease.

### 7.2 Storage Do not expose to direct sunlight for long periods of time. Keep away from moisture. Store below 80 F out of direct sunlight in dry location. Keep away from heat. Store in cool, dry place to avoid blocking. Use with adequate ventilation. 

## 8. Exposure Controls/Personal Protection 8.1 Exposure Controls Avoid creating dust. If airborne contaminants are generated when the material is heated, handled, or transported, appropriate administrative and engineering controls, including sufficient ventilation in volume and air flow patterns, should be provided to keep air contaminant concentration levels below acceptable criteria. Minimize the collection (build-up) of dust on walls, floors, sills, ledges, machinery, or equipment. Work clothes should be changed daily and washed to prevent dust contact. These techniques may not necessarily address all issues pertaining to your operation. We, therefore, recommend that you consult with experts of your choice to determine whether or not your programs are adequate. Consult OSHA, state/provincial and local laws, and regulations. Review ASTM E 1132-99, "Standard Practice for Health Requirements Relating to Occupational Exposure to Respirable Crystalline Silica," as well as other guidelines such as NIOSH publications. 

### 8.2 Personal Protection Where air contaminants can exceed acceptable criteria, use NIOSH/MSHA approved respiratory protection equipment. Respirators should be selected based on the form and concentration of contaminants in air in accordance with OSHA laws and regulations or other applicable standards or guidelines, including ANSI standards regarding respiratory protection. Wear impervious gloves as required to prevent skin contact. Wear safety glasses with sideshields at all times to prevent eye irritation.

### 11. TOXICOLOGICAL INFORMATION Principle Route of Exposure Eye or skin contact, inhalation. Inhalation May cause allergic respirator y reaction. 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 experim ental animals 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 lung damage may be occurring. Inhalation of dust may also have serious chronic health effects (See "Chr onic Effects/Carcinogenicity" subsection below).

Skin Contact May cause skin irritation. May cause a rash and itching of the skin. Eye Contact May cause eye irritation. Ingestion None known Aggravated Medical Conditions Individuals with respiratory disease, including but not limited to asthma and bronchitis, or subject to eye irritation, should not be exposed to quartz dust. Chronic Effects/Carcinogenicity Silicosis: Excessive inhalation of resp irable crystalline silica dust may cause a progressive, disabling, and sometimes-fatal lung disease called silicosis. Symptoms include cough, shortness of breath, w heezing, non-specific chest illness, and reduced pulmonary function. This disease is exacerbated by smoking. Individuals with silicosis are predisposed to develop tuberculosis. Cancer Status: The International A gency for Research on Cancer (IARC) has determined that crystalline silica inhaled in the form of quartz or cristobalite from occupational sources can cause lung canc er in humans (Group 1 - carcinogenic to humans) and has determined that there is sufficient evidence in experimental animals for the carcinogenicity of trid ymite (Group 2A - possible carcinogen to humans). Refer to IARC Monograph 68, Silica, Some Silicates and Organic Fibres (June 1997) in conjunction with the use of these minerals. The National Toxicology Program classifies respirable crystalline silica as "Known to be a human carcinogen". Refer to the 9th Report on Carcinogens (2000). The American Conference of Governmental Industrial Hygienists (ACGIH) classifies crystalline silica, quartz, as a suspected human carcinogen (A2).

### 11. TOXICOLOGICAL INFORMATION Principle Route of Exposure Eye or skin contact, inhalation. Inhalation May cause allergic respirator y reaction. 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 experim ental animals 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 lung damage may be occurring. Inhalation of dust may also have serious chronic health effects (See "Chr onic Effects/Carcinogenicity" subsection below).

Skin Contact May cause mechanical skin irritation. May cause an allergic skin reaction. Eye Contact May cause eye irritation. Ingestion None known Aggravated Medical Conditions Individuals with respiratory disease, including but not limited to asthma and bronchitis, or subject to eye irritation, should not be exposed to quartz dust. Chronic Effects/Carcinogenicity Silicosis: Excessive inhalation of resp irable crystalline silica dust may cause a progressive, disabling, and sometimes-fatal lung disease called silicosis. Symptoms include cough, shortness of breath, w heezing, non-specific chest illness, and reduced pulmonary function. This disease is exacerbated by smoking. Individuals with silicosis are predisposed to develop tuberculosis. Cancer Status: The International A gency for Research on Cancer (IARC) has determined that crystalline silica inhaled in the form of quartz or cristobalite from occupational sources can cause lung canc er in humans (Group 1 - carcinogenic to humans) and has determined that there is sufficient evidence in experimental animals for the carcinogenicity of trid ymite (Group 2A - possible carcinogen to humans). Refer to IARC Monograph 68, Silica, Some Silicates and Organic Fibres (June 1997) in conjunction with the use of these minerals. The National Toxicology Program classifies respirable crystalline silica as "Known to be a human carcinogen". Refer to the 9th Report on Carcinogens (2000). The American Conference of Governmental Industrial Hygienists (ACGIH) classifies crystalline silica, quartz, as a suspected human carcinogen (A2). There is some evidence that breathing re spirable crystalline silica or the disease silicosis is associated with an increased incidence of significant disease endpoints such as scleroderma (an immune system disorder manifested by scarring of the lungs, skin, and other internal organs) and kidney disease.

### Delayed Hazards
7631-86-9 Silica Can cause lung fibrosis. Pre-existing respiratory disorders may be aggravated by exposure. -- See Footnote 14464-46-1 Cristobalite CANCER HAZARD. Can cause cancer. Use of this product may generate silica dust (which may be invisible). Inhaled silica has been cla ssified by IARC as a human carcinogen. Inhalation of silica dust may cause delayed lung inju ry or lung fibrosis (including silicosis and/or pneumoconiosis) and/or other diseases which may lead to permanent disability and/or death. Silicosis is a form of disabling pulmonary fibrosis which can be progressive. Prolonged exposure to respirable silica may cause diminished lung capacity with shortnes s of breath during physical exertion and may cause fatigue, breathlessness, wheezing, cough, and sputum production. Pre-existing respiratory disorders may be aggravated by exposure. Smoking may aggravate th e effects of exposure and may increase the risk of developing respiratory disease from exposure. Consult with your employer and your doctor for further information or if you believe you may be developing any breathing or lung problems. There is some evidence that breathing respirable crystalline silica or the disease silicosis is associated with an increased incidence of significant disease endpoints such as scleroderma (an immune system disorder manifested by fibrosis of the lungs, skin and other internal organs) and kidney disease. Silicosis is also reported to increase the risk of tuberculosis. Footnote: As of the date of issuance of this do cument, this material has not been listed by NTP, classified by IARC nor regulate d by OSHA as a carcinogen. 

## 4. First Aid Measures INGESTION: If accidentally swallowed, dilute by drinking large quantities of water. Immediately contact poison control center or hospital emergency room for any other additional treatment directions. INHALATION: Remove to fresh air. SKIN: In case of irritation, flush with water.

### 3.2 Potential Health Effects Immediate Hazards

INGESTION: No hazards known to company. INHALATION: Not expected to be harmful unde r normal conditions of use. However, if allowed to become airborne, may cause irritation of nose, throat and lungs. SKIN: May cause irritation on prolonged or repeated contact. EYES: May cause irritation on prolonged or repeated contact.



### Delayed Hazards
Silica 7631-86-9 Can cause lung fibrosis. Pre-existing respiratory disorders may be aggravated by exposure. -- See Footnote Cristobalite 14464-46-1 CANCER HAZARD. Can cause cancer. Use of this product may generate silica dust (which may be invisible). Inhaled silica has been cla ssified by IARC as a human carcinogen. Inhalation of silica dust may cause delayed lung inju ry or lung fibrosis (including silicosis and/or pneumoconiosis) and/or other diseases which may lead to permanent disability and/or death. Silicosis is a form of disabling pulmonary fibrosis which can be progressive. Prolonged exposure to respirable silica may cause diminished lung capacity with shortnes s of breath during physical exertion and may cause fatigue, breathlessness, wheezing, cough, and sputum production. Pre-existing respiratory disorders may be aggravated by exposure. Smoking may aggravate th e effects of exposure and may increase the risk of developing respiratory disease from exposure. Consult with your employer and your doctor for further information or if you believe you may be developing any breathing or lung problems. There is some evidence that breathing respirable crystalline silica or th e disease silicosis is associated with an increased incidence of significant disease endpoints such as scleroderma (an immune system disorder manifested by fibrosis of the lungs, skin and other internal organs) and kidney disease. Silicosis is also reported to increase the risk of tuberculosis. Hexamethylenetetramine 100-97-0 May cause allergic skin and respiratory reactions. -- See Footnote Footnote: As of the date of issuance of this do cument, this material has not been listed by NTP, classified by IARC nor regulate d by OSHA as a carcinogen. 

## 4. First Aid Measures INGESTION: If accidentally swallowed, dilute by drinking large quantities of water. Immediately contact poison control center or hospital emergency room for any other additional treatment directions. INHALATION: Remove to fresh air. SKIN: In case of irritation, flush with water.

### 11. TOXICOLOGICAL INFORMATION Principle Route of Exposure Eye or skin contact, inhalation.

SAND - COMMON BROWN Page 3 of 6Inhalation 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 experimental animals for the carcinogeni city 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 lung damage may be occurring. Inhalation of dust may also have serious chronic health effects (See "Chr onic Effects/Carcinogenicity" subsection below).

Skin Contact None known. Eye Contact May cause mechanical irritation to eye. Ingestion None known Aggravated Medical Conditions Individuals with respiratory disease, including but not limited to asthma and bronchitis, or subject to eye irritation, should not be exposed to quartz dust. Chronic Effects/Carcinogenicity Silicosis: Excessive inhalation of resp irable crystalline silica dust may cause a progressive, disabling, and sometimes-fatal lung disease called silicosis. Symptoms include cough, shortness of breath, w heezing, non-specific chest illness, and reduced pulmonary function. This disease is exacerbated by smoking. Individuals with silicosis are predisposed to develop tuberculosis. Cancer Status: The International A gency for Research on Cancer (IARC) has determined that crystalline silica inhaled in the form of quartz or cristobalite from occupational sources can cause lung canc er in humans (Group 1 - carcinogenic to humans) and has determined that there is sufficient evidence in experimental animals for the carcinogenicity of trid ymite (Group 2A - possible carcinogen to humans). Refer to IARC Monograph 68, Silica, Some Silicates and Organic Fibres (June 1997) in conjunction with the use of these minerals. The National Toxicology Program classifies respirable crystalline silica as "Known to be a human carcinogen". Refer to the 9th Report on Carcinogens (2000). The American Conference of Governmental Industrial Hygienists (ACGIH) classifies crystalline silica, quartz, as a suspected human carcinogen (A2). There is some evidence that breathing re spirable crystalline silica or the disease silicosis is associated with an increased incidence of significant disease endpoints such as scleroderma (an immune system disorder manifested by scarring of the lungs, skin, and other internal organs) and kidney disease.

Other Information For further information consult "Adverse Effects of Crystalline Silica Exposure" published by the American Thoracic Societ y Medical Section of the American Lung Association, American Journal of Respir atory and Critical Care Medicine, Volume 155, pages 761-768 (1997).

### 11. TOXICOLOGICAL INFORMATION Principle Route of Exposure Eye or skin contact, inhalation.

SAND - RESIEVED Page 3 of 6Inhalation 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 experimental animals for the carcinogeni city 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 lung damage may be occurring. Inhalation of dust may also have serious chronic health effects (See "Chr onic Effects/Carcinogenicity" subsection below).

Skin Contact None known. Eye Contact May cause mechanical irritation to eye. Ingestion None known Aggravated Medical Conditions Individuals with respiratory disease, including but not limited to asthma and bronchitis, or subject to eye irritation, should not be exposed to quartz dust. Chronic Effects/Carcinogenicity Silicosis: Excessive inhalation of resp irable crystalline silica dust may cause a progressive, disabling, and sometimes-fatal lung disease called silicosis. Symptoms include cough, shortness of breath, w heezing, non-specific chest illness, and reduced pulmonary function. This disease is exacerbated by smoking. Individuals with silicosis are predisposed to develop tuberculosis. Cancer Status: The International A gency for Research on Cancer (IARC) has determined that crystalline silica inhaled in the form of quartz or cristobalite from occupational sources can cause lung canc er in humans (Group 1 - carcinogenic to humans) and has determined that there is sufficient evidence in experimental animals for the carcinogenicity of trid ymite (Group 2A - possible carcinogen to humans). Refer to IARC Monograph 68, Silica, Some Silicates and Organic Fibres (June 1997) in conjunction with the use of these minerals. The National Toxicology Program classifies respirable crystalline silica as "Known to be a human carcinogen". Refer to the 9th Report on Carcinogens (2000). The American Conference of Governmental Industrial Hygienists (ACGIH) classifies crystalline silica, quartz, as a suspected human carcinogen (A2). There is some evidence that breathing re spirable crystalline silica or the disease silicosis is associated with an increased incidence of significant disease endpoints such as scleroderma (an immune system disorder manifested by scarring of the lungs, skin, and other internal organs) and kidney disease.

Other Information For further information consult "Adverse Effects of Crystalline Silica Exposure" published by the American Thoracic Societ y Medical Section of the American Lung Association, American Journal of Respir atory and Critical Care Medicine, Volume 155, pages 761-768 (1997).

SKIN: May cause irritation on prolonged or repeated contact. EYES: May cause irritation on prolonged or repeated contact. 

### Delayed Hazards
14808-60-7 Quartz (SiO2) CANCER HAZARD. Can cause cancer. Use of this product may generate silica dust (which may be invisible). Inhaled silica has been cla ssified by IARC as a human carcinogen. Inhalation of silica dust may cause delayed lung inju ry or lung fibrosis (including silicosis and/or pneumoconiosis) and/or other diseases which may lead to permanent disability and/or death. Silicosis is a form of disabling pulmonary fibrosis which can be progressive. Prolonged exposure to respirable silica may cause diminished lung capacity with shortnes s of breath during physical exertion and may cause fatigue, breathlessness, wheezing, cough, and sputum production. Pre-existing respiratory disorders may be aggravated by exposure. Smoking may aggravate th e effects of exposure and may increase the risk of developing respiratory disease from exposure. Consult with your employer and your doctor for further information or if you believe you may be developing any breathing or lung problems. There is some evidence that breathing respirable crystalline silica or the disease silicosis is associated with an increased incidence of significant disease endpoints such as scleroderma (an immune system disorder manifested by fibrosis of the lungs, skin and other internal organs) and kidney disease. Silicosis is also reported to increase the risk of tuberculosis.


## 4. First Aid Measures INGESTION: If accidentally swallowed, dilute by drinking large quantities of water. Immediately contact poison control center or hospital emergency room for any other additional treatment directions. INHALATION: Remove to fresh air. SKIN: In case of irritation, flush with water.

### 11. TOXICOLOGICAL INFORMATION Principle Route of Exposure Eye or skin contact, inhalation.

SILICA FLOUR - SSA-1 Page 3 of 6Inhalation 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 experimental animals for the carcinogeni city 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 lung damage may be occurring. Inhalation of dust may also have serious chronic health effects (See "Chr onic Effects/Carcinogenicity" subsection below).

Skin Contact None known. Eye Contact May cause mechanical irritation to eye. Ingestion None known Aggravated Medical Conditions Individuals with respiratory disease, including but not limited to asthma and bronchitis, or subject to eye irritation, should not be exposed to quartz dust. Chronic Effects/Carcinogenicity Silicosis: Excessive inhalation of resp irable crystalline silica dust may cause a progressive, disabling, and sometimes-fatal lung disease called silicosis. Symptoms include cough, shortness of breath, w heezing, non-specific chest illness, and reduced pulmonary function. This disease is exacerbated by smoking. Individuals with silicosis are predisposed to develop tuberculosis. Cancer Status: The International A gency for Research on Cancer (IARC) has determined that crystalline silica inhaled in the form of quartz or cristobalite from occupational sources can cause lung canc er in humans (Group 1 - carcinogenic to humans) and has determined that there is sufficient evidence in experimental animals for the carcinogenicity of trid ymite (Group 2A - possible carcinogen to humans). Refer to IARC Monograph 68, Silica, Some Silicates and Organic Fibres (June 1997) in conjunction with the use of these minerals. The National Toxicology Program classifies respirable crystalline silica as "Known to be a human carcinogen". Refer to the 9th Report on Carcinogens (2000). The American Conference of Governmental Industrial Hygienists (ACGIH) classifies crystalline silica, quartz, as a suspected human carcinogen (A2). There is some evidence that breathing re spirable crystalline silica or the disease silicosis is associated with an increased incidence of significant disease endpoints such as scleroderma (an immune system disorder manifested by scarring of the lungs, skin, and other internal organs) and kidney disease.

Other Information For further information consult "Adverse Effects of Crystalline Silica Exposure" published by the American Thoracic Societ y Medical Section of the American Lung Association, American Journal of Respir atory and Critical Care Medicine, Volume 155, pages 761-768 (1997). Toxicity Tests Oral Toxicity: Not determined Dermal Toxicity: Not determined Inhalation Toxicity: Not determined Primary Irritation Effect: Not determined Carcinogenicity Refer to IARC Monograph 68, Silica, Some Silicates and Organic Fibres (June 1997).

### 11. TOXICOLOGICAL INFORMATION Principle Route of Exposure Eye or skin contact, inhalation.

SSA-2 Page 3 of 6Inhalation 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 experimental animals for the carcinogeni city 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 lung damage may be occurring. Inhalation of dust may also have serious chronic health effects (See "Chr onic Effects/Carcinogenicity" subsection below).

Skin Contact None known. Eye Contact May cause mechanical irritation to eye. Ingestion None known Aggravated Medical Conditions Individuals with respiratory disease, including but not limited to asthma and bronchitis, or subject to eye irritation, should not be exposed to quartz dust. Chronic Effects/Carcinogenicity Silicosis: Excessive inhalation of resp irable crystalline silica dust may cause a progressive, disabling, and sometimes-fatal lung disease called silicosis. Symptoms include cough, shortness of breath, w heezing, non-specific chest illness, and reduced pulmonary function. This disease is exacerbated by smoking. Individuals with silicosis are predisposed to develop tuberculosis. Cancer Status: The International A gency for Research on Cancer (IARC) has determined that crystalline silica inhaled in the form of quartz or cristobalite from occupational sources can cause lung canc er in humans (Group 1 - carcinogenic to humans) and has determined that there is sufficient evidence in experimental animals for the carcinogenicity of trid ymite (Group 2A - possible carcinogen to humans). Refer to IARC Monograph 68, Silica, Some Silicates and Organic Fibres (June 1997) in conjunction with the use of these minerals. The National Toxicology Program classifies respirable crystalline silica as "Known to be a human carcinogen". Refer to the 9th Report on Carcinogens (2000). The American Conference of Governmental Industrial Hygienists (ACGIH) classifies crystalline silica, quartz, as a suspected human carcinogen (A2). There is some evidence that breathing re spirable crystalline silica or the disease silicosis is associated with an increased incidence of significant disease endpoints such as scleroderma (an immune system disorder manifested by scarring of the lungs, skin, and other internal organs) and kidney disease.

Other Information For further information consult "Adverse Effects of Crystalline Silica Exposure" published by the American Thoracic Societ y Medical Section of the American Lung Association, American Journal of Respir atory and Critical Care Medicine, Volume 155, pages 761-768 (1997). Toxicity Tests Oral Toxicity: Not determined Dermal Toxicity: Not determined Inhalation Toxicity: Not determined Primary Irritation Effect: Not determined Carcinogenicity Refer to IARC Monograph 68, Silica, Some Silicates and Organic Fibres (June 1997).

There is sufficient evidence in experim ental animals 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 lung damage may be occurring. Inhalation of dust may also have serious chronic health effects (See "Chr onic Effects/Carcinogenicity" subsection below).

Skin Contact May cause skin irritation. May cause a rash and itching of the skin. Eye Contact May cause eye irritation. Ingestion None known Aggravated Medical Conditions Individuals with respiratory disease, including but not limited to asthma and bronchitis, or subject to eye irritation, should not be exposed to quartz dust. Chronic Effects/Carcinogenicity Silicosis: Excessive inhalation of resp irable crystalline silica dust may cause a progressive, disabling, and sometimes-fatal lung disease called silicosis. Symptoms include cough, shortness of breath, w heezing, non-specific chest illness, and reduced pulmonary function. This disease is exacerbated by smoking. Individuals with silicosis are predisposed to develop tuberculosis. Cancer Status: The International A gency for Research on Cancer (IARC) has determined that crystalline silica inhaled in the form of quartz or cristobalite from occupational sources can cause lung canc er in humans (Group 1 - carcinogenic to humans) and has determined that there is sufficient evidence in experimental animals for the carcinogenicity of trid ymite (Group 2A - possible carcinogen to humans). Refer to IARC Monograph 68, Silica, Some Silicates and Organic Fibres (June 1997) in conjunction with the use of these minerals. The National Toxicology Program classifies respirable crystalline silica as "Known to be a human carcinogen". Refer to the 9th Report on Carcinogens (2000). The American Conference of Governmental Industrial Hygienists (ACGIH) classifies crystalline silica, quartz, as a suspected human carcinogen (A2). There is some evidence that breathing re spirable crystalline silica or the disease silicosis is associated with an increased incidence of significant disease endpoints such as scleroderma (an immune system disorder manifested by scarring of the lungs, skin, and other internal organs) and kidney disease.

Other Information For further information consult "Adverse Effects of Crystalline Silica Exposure" published by the American Thoracic Societ y Medical Section of the American Lung Association, American Journal of Respir atory and Critical Care Medicine, Volume 155, pages 761-768 (1997).

### 11. TOXICOLOGICAL INFORMATION Principle Route of Exposure Eye or skin contact, inhalation. 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 experimental animals for the carcinogeni city 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 lung damage may be occurring. Inhalation of dust may also have serious chronic health effects (See "Chr onic Effects/Carcinogenicity" subsection below).

Skin Contact May cause mechanical skin irritation. Eye Contact May cause eye irritation. Ingestion None known Aggravated Medical Conditions Individuals with respiratory disease, including but not limited to asthma and bronchitis, or subject to eye irritation, should not be exposed to quartz dust. Chronic Effects/Carcinogenicity Silicosis: Excessive inhalation of resp irable crystalline silica dust may cause a progressive, disabling, and sometimes-fatal lung disease called silicosis. Symptoms include cough, shortness of breath, w heezing, non-specific chest illness, and reduced pulmonary function. This disease is exacerbated by smoking. Individuals with silicosis are predisposed to develop tuberculosis. Cancer Status: The International A gency for Research on Cancer (IARC) has determined that crystalline silica inhaled in the form of quartz or cristobalite from occupational sources can cause lung canc er in humans (Group 1 - carcinogenic to humans) and has determined that there is sufficient evidence in experimental animals for the carcinogenicity of trid ymite (Group 2A - possible carcinogen to humans). Refer to IARC Monograph 68, Silica, Some Silicates and Organic Fibres (June 1997) in conjunction with the use of these minerals. The National Toxicology Program classifies respirable crystalline silica as "Known to be a human carcinogen". Refer to the 9th Report on Carcinogens (2000). The American Conference of Governmental Industrial Hygienists (ACGIH) classifies crystalline silica, quartz, as a suspected human carcinogen (A2). There is some evidence that breathing re spirable crystalline silica or the disease silicosis is associated with an increased incidence of significant disease endpoints such as scleroderma (an immune system disorder manifested by scarring of the lungs, skin, and other internal organs) and kidney disease.

Other Information For further information consult "Adverse Effects of Crystalline Silica Exposure" published by the American Thoracic Societ y Medical Section of the American Lung Association, American Journal of Respir atory and Critical Care Medicine, Volume 155, pages 761-768 (1997).
