### 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.

National Premium Gold Page 4 of 7Chronic 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).

Provide exhaust ventilation or other engineering controls to keep the airborne concentrations of vapors or particles below their respective threshold limit value. Ensure that eyewash stations and safety showers are proximal to the work-station location. 

### Engineering Controls

Respirator use is not expected to be necessary under normal conditions of use. In poorly ventilated areas, emergency situations or if exposure levels are exceeded, use NIOSH approved full face respirator. Chemical safety goggles. Use full face shield if splashes could occur. Wear long sleeves and chemical resistant apron to prevent repeated or prolonged skin contact.

Chemical resistant gloves. Nitrile or Neoprene gloves. Chemical resistant boots or overshoes. 

### Personal Protection

Eyes Body Respiratory

Hands Feet Other information Nitrile or neoprene gloves. 

### Additional Exposure Control Remarks Not available. Personal Protective Equipment recommendations are based on anticipated known manufacturing and use conditions. These conditions are expected to result in only incidental exposure. A thorough review of the job tasks and conditions by a safety professional is recommended, however, to determine the level of personal protective equipment appropriate for these job tasks and conditions. While trimethylbenzene isomers do not have exposure limits, trimethylbenzene (mixed isomers) (CAS No. 25551-13-7) has TWA value of 25 ppm for both ACGIH and OSHA (revoked limit). The OSHA permissible exposure levels shown above are the OSHA 1989 levels or from subsequent OSHA regulatory actions. Although the 1989 levels have been vacated the 11th Circuit Court of Appeals, Baker Petrolite Corporation recommends that these lower exposure levels be observed as reasonable worker protection.

### Component Toxicological Information

1) Light aromatic naphtha Solvent naphtha (petroleum), light aromatic is a component of this product. Solvent naphtha (petroleum), light aromatic may cause damage to the peripheral nerves, resulting in numbness or tingling of the extremities with chronic (long term) exposure to high concentrations. (Micromedex) Rats exposed for 4 months to 1700 ppm of a solvent similar to this product showed evidence of mild damage to the liver, lungs and kidneys. These effects were not seen in rats exposed for one year to 350 ppm of another similar solvent. Rats exposed to vapors of a similar solvent during pregnancy showed embryo/fetotoxicity at concentrations producing maternal toxicity. In response to a TSCA test rule, several studies of a solvent similar to this product were completed. Mutagenicity studies and a rat inhalation neurotoxicity study were negative. In a mouse developmental effects study, reduced fetal body weight was seen but no teratogenicity. A rat reproductive effects study demonstrated toxicity but little effect on reproductive parameters. (Vendor MSDS) Ingestion has produced Central Nervous System effects in laboratory animals. (EPA/OTS 87-8214199 and 88-920000348) 2) 1,2,4-Trimethylbenzene 

## Continued on Next Page

## PAO72 ASPHALTENE DISPERSANT Page: 6/9 1,2,4-Trimethylbenzene, also know as pseudocumene, is a component of this product. Chronic pseudocumene exposure may provoke bronchospasm with cough and wheezing (Plunkett, 1976; ACGIH, 1991; Battig et al, 1956). Respiratory distress was noted in experimental animals following sub acute inhalation exposure (Gage, 1970). Nervousness and anxiety were noted with chronic occupational exposure (Battig et al, 1956; ACGIH, 1991). At the time of this review, no studies were found on the potential adverse reproductive effects of pseudocumene in humans, but trimethylbenzenes (including pseudocumene) can cross the placental barrier (Clayton & Clayton, 1994; Doroty et al, 1976). In an experimental animal study, offspring born to pregnant rats exposed to pseudocumene were healthy at birth and grew normally (Cameron et al, 1938). Blood effects such as anemia and delayed clotting time have been noticed in workers chronically exposed to a solvent containing trimethylbenzene. The blood effects, however, may have been due to a contaminant in the solvent such as benzene (a known blood toxin). 3) Alkyl benzenesulfonic acid Alkylbenzene sulfonic acid is a component of this product. Chronic inhalation causes swelling of the lungs, bronchial emphysema, and dental erosion ( MSDS). 4) 1,3,5-Trimethylbenzene 1,3,5-Trimethylbenzene (Mysitylene) is a component of this product. Chronic asthmatic-like bronchitis may be a delayed chronic hazard (EPA, 1985; Laham, 1987; HSDB, 1997). Nervousness, tension, and anxiety have been noted in chronically exposed workers with exposure to a mixture of solvents including mesitylene (HSDB, 1997). Elevated alkaline phosphates and SGOT(liver enzymes) levels have been noted in chronic animal inhalation studies (Clayton & Clayton, 1994). These effects have not been reported in exposed humans. (Reprotext) Thrombocytopenia (a lack of platelets in the blood) with bleeding from the gums and nose and mild anemia may occur with chronic exposure to mesitylene as a component of the commercial solvent mixture, "Fleet-X-DV-99" (Plunkett, 1976; Finkel, 1983; HSDB, 1997). Coagulation (clotting of the blood) times were delayed by about 40% in a group of workers chronically exposed to a mixture of solvents containing about 30% mesitylene (Laham, 1987). These hematological disorders may have been due to a contaminant, such as benzene (Hathaway et al, 1996). Thrombocytosis (an increase of platelets in the blood) and thrombocytopenia have been noted in rabbits (Clayton & Clayton, 1994). (Reprotext) 1,3,5-Trimethylbenzene has been positive in a mutagenicity assay (Lewis, 1992). (Reprotext) 5) 1,2,3-Trimethylbenzene Not available. 6) Xylene Xylene (mixed isomers) is a component of this product. Effects of chronic exposure to xylene are similar to those of acute exposure, but may be more severe. Chronic inhalation reportedly was associated with headache, tremors, apprehension, memory loss, weakness, dizziness, loss of appetite, nausea, ringing in the ears, irritability, thirst, anemia, mucosal bleeding, enlarged liver, and hyperplasia, but not destruction of the bone marrow (Clayton & Clayton, 1994; ILO, 1983). Some earlier reports of effects of chronic exposure to xylene have been questioned, as exposures were not limited to xylene alone. Effects on the blood have been reported from chronic exposure to as little as 50 mg/m3 (Pap & Varga, 1987). Repeated exposure can damage bone marrow, causing low blood cell count and can damage the liver and kidneys (NJ Department of Health, Hazardous Substance Fact Sheet). Chronic xylene exposure (usually mixed with other solvents) has produced irreversible damage to the CNS (ILO, 1983). CNS effects may be exacerbated by ethanol abuse (Savolainen, 1980). Xylene may damage hearing or enhance sensitivity to noise in chronic occupational exposures (Morata et al, 1994), probably from neurotoxic mechanism. Tolerance to xylene can occur over the work week and disappear over the weekend. (ACGIH, 1992). Inhalation exposure has produced fetotoxicity and postnatal developmental toxicity in laboratory animals. (API, 1978, Kensington, MD, EPA/OTS Document No. 878210350 and Hass, U., et al, 1995, Neurotoxicology and Teratology 17: 341- 349 and 1997, Neurotoxicology 18: 547-552)

Product Bulletin


# G ENERAL 

# I NFORMATION Plexsurf WRS-A is a blend of conventional anionic and fluorocarbo n surfactants, which work synergistically to give very low surface tensions and negligible absorption to rock in well treating fluids. These features promote load recovery, particularly in gas well applications. Plexsurf WRS-A shows very low tendency to form emulsions at recommended loadings. 

# P HYSICAL 

# P ROPERTIES Density: 7.81 lb./gal Ionic Charge: Anionic Solubility in water: Soluble Solubility in diesel: Insoluble App earance: Pale yellow liquid Odor: Mild alcohol Flash point: 56 ° F 

# C HEMICAL 

# D ESCRIPTION Plexsurf WRS-A contains fluorosurfactants, and conventional anionic surfactants, in an aqueous alcohol base. 

# R ECOMMENDED 

# U SES Plexsurf WRS-A is recommended for use particularly in fracturing treatments on gas zones, especially in tighter formations that have a history of being slow to unload. The product is effective in either sandstone or carbonates. 

# T REATING 

# A PPLICATIONS The typical loading of Plexsurf WRS-A in fracturing fluids is 0.5 to 1 gallon per thousand gallons throughout the job. Plexsurf WRS-A is not known to interfere with crosslinkers, breakers, or other fracturing additives at this loading; it is, however, incompatible with polymeric clay stabilizers. If run in acid treatment loadings of up to 2 gallons/1000 may be required for optimal surface tension reduction. Use of nonionic non-emulsifiers with Plexsurf WRS-A , though perfectly acceptable, is often not required due to the NE properties of the product. 

# P ACKAGING Plexsurf WRS-A is obtainable in 55-gallon poly drums, 330-gallon poly totes and Bulk storage DOT information: Flammable liquid, n.o.s., 3, U N 1993, PG II 

# A VAILABILITY Plexsurf WRS-A is available from Chemplex, Ltd. at any of our stocking locations. Updated 4-24-07

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

SAND - PREMIUM 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.

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

SAND - BRADY

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-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).

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 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.

### 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. 

## 6. Accidental Release MeasuresPage

XRT TM AcFrac ® Gold, all sizes Version: 2 Printed: 01/15/2004 3/6 Sweep (scoop) up and remove to a chemical disposal area. Prevent entry into natural bodies of water. 

## 7. Handling and Storage 7.1 Handling Handle in accordance with good industrial hygi ene and safety practices. These practices include avoiding unnecessary exposure and removal of the material from eyes, skin and clothing. Wash thoroughly after handling. Always use appropriate Personal Protective Equipment (PPE). INHALATION: Avoid prolonged or repeated breathing of dust or vapor. SKIN: Avoid prolonged or repeated contact with skin and clothing. EYES: Avoid prolonged or repeat ed contact with eyes. 

### 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 Cont rols/Personal Protection 8.1 Exposure Controls If airborne contaminants are generated when the material is heated or handled, sufficient ventilation in volume and air flow patterns should be provided to keep air contaminant concentration levels below acceptable criteria.



### 8.2 Personal Protection Where air contaminants can exceed acceptable cr iteria, use NIOSH (42 CFR Part 84) 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.
