The table is not exhaustive and will be updated periodically. A. OSHA Standards The OSHA TWA-PELs (Time Weighted Average), given as workshift time weighted averages, are taken from the Federal Register as found in 29 CRF 1910.1000 as of 19 Januaiy 1989 and are summarized in the "NIOSH/OSHA Pocket Guide to Chemical Hazards." Also included in parentheses are the current ACGIH (American Conference of Governmental Industrial Hygienist) values in cases where they differ from OSHA TWAs. These values are subject to change, and appropriate publications should be consulted for the most current information. B. Monitor Samples Information Sampling Rate All sampling rates have an accuracy of 5%. The (*) compounds in the Sampling Guide tables have been subjected to an extensive amount of laboratory work to verify the sampling rate. The sampling rates given for the remaining compounds in this table were determined from empirical relationships as outlined in a publication on Sampling Rate Validation. The sampling rates are tabulated as cubic centimeters/minute and micrograms/ppm-hour. The publication on Sampling Rate Validation Protocol can be obtained upon request from 3M. The top section of the 3520 (containing the primary adsorbent) has the same geometric dimension as the 3M Organic Vapor Monitor 3500. Therefore, the sampling rate is the same, and also has an accuracy of 5%. Capacity The capacity of the monitor for each individual compound is a function of molecular structure, vapor pressure, environmental conditions, etc. The capacity values are tabulated in Section II Analysis Guide, and are used to determine the length of a recommended sampling period. Because of the backup section, the effective sampling capacity of the Organic Vapor Monitor 3520 is four times greater than the values listed for the Organic Vapor Monitor 3500/3510. When sampling environments containing contaminant mixtures or environments with high relative humidity, it is difficult to accurately define the diffusional sampling capacity. Therefore, under these conditions, the weight (Ws) collected by the secondary adsorbent of the backup section can be compared with the weight (Wp) collected by the primary adsorbent to determine sample validity. The ratio WsAA/p must be equal to or less than 0.50. C. Length of Sampling Period 1. General 3500/3510 When sampling for organic contaminants, full workshift sampling periods are recommended as the most comprehensive measures of worker exposure. When sampling some organic contaminants, sampling periods shorter than a full workshift are required in order to sample within the recommended capacity of the monitor. Under these circumstances, sequential sampling with several monitors can be performed. 3520 For those compounds where the recommended length of the sampling period for the Organic Vapor Monitor 3500/3510 is less than a full workshift, the length of the sampling period can be increased by a factor of up to four when using the 3520 Organic Vapor Monitor. 3M 005234 1 2. Effect of Humidity Recommended sampling periods have been tabulated for concentration ranges from 0.1 to 0.5 times the PEL and from 0.5 to 3 times the PEL for relative humidities less than or greater than 70%. These recommended sampling periods should not be exceeded when using OVM 3500/3510. 3. Minimum Sampling Time To confirm quantitatively the presence and concentration of a contaminant in the atmosphere, most analysts must have a minimum of 10 micrograms forG.C. analysis. A sampling period of at least 15 minutes is recommended even when 10 micrograms of the contaminant could be collected in a shorter period. For a contaminant at a low concentration level, the sampling rate of micrograms/ppm-hr. should be used to verify a sampling period during which at least 10 micrograms of the contaminant would be collected. D. Short Term Exposure Limit (STEL) The ACGIH has recommended a short-term exposure limit (STEL) as a maximum concentration to which workers can be exposed for a period up to 15 minutes continuously. No more than four (4) such excursions per day are permitted, with at least 60 minutes between exposure periods, provided that the recommended ACGIH daily TLV-TWA also is not exceeded. The STEL values summarized in the following tables can be found in the "Threshold Limit Values and Biological Exposure Indices Adopted by ACGIH for 1989-1990." The monitor Is recommended for STEL sampling if, during the 15 minute sampling period, the monitor collects a sufficient quantity of the contaminant for analysis. E. Unsuitable Compounds The OVM is not recommended for the compounds listed below because of adverse or inadequate interactions with the sorbent material. This list is representative of classes of compounds not suitable for use with the OVM. Compounds not on this list or the Compound Guide should be handled by consultation with OH&ESD Technical Service at 1-800-243-4630.

The table is not exhaustive and will be updated periodically. A. OSHA Standards The OSHA TWA-PELs (Time Weighted Average), given as workshift time weighted averages, are taken from the Federal Register as found in 29 CRF 1910.1000 as of 1 January 1977 and are summarized in the "NIOSH/OSHA Pocket Guide to Chemical Hazards." Also included in parentheses are the current ACGIH (American Conference of Governmental Industrial Hygienist) values in cases where they differ from OSHA TWAs. These values are subject to change, and appropriate publications should be consulted for the most current information, B. Monitor Samples Information Sampling Rate All sampling rates have an accuracy of 5%. The (*) compounds in the Sampling Guide tables have been subjected to an extensive amount of laboratory work to verify the sampling rate. The sampling rates given for the remaining compounds in this table were determined from empirical relationships as outlined in a publication on Sampling Rate Validation. The sampling rates are tabulated as cubic centimeters/minute and micrograms/ppm-hour. The publication on Sampling Rate Validation Protocol can be obtained upon request from 3M. The top section of the 3520 (containing the primary adsorbent) has the same geometric dimension as the 3M Organic Vapor Monitor 3500. Therefore, the sampling rate is the same, and also has an accuracy of 5%. Capacity The capacity of the monitor for each individual compound is a function of molecular structure, vapor pressure, environmental conditions, etc. The capacity values are tabulated in Section II Analysis Guide, and are used to determine the length of a recommended sampling period. Because of the backup section, the effective sampling capacity of the Organic Vapor Monitor 3520 is four times greater than the values listed for the Organic Vapor Monitor 3500/3510. When sampling environments containing contaminant mixtures on environments with high relative humidity, it is difficult to accurately define the diffusional sampling capacity. Therefore, under these conditions, the weight (Ws) collected by the secondary adsorbent of the backup section can be compared with the weight (Wp) collected by the primary adsorbent to determine sample validity. The ratio Ws/Wp must be equal to or less than 0.50. C. Length of Sampling Period 1. General 3500/3510 When sampling for organic contaminants, full workshift sampling periods are recommended as the most comprehensive measures of worker exposure. When sampling some organic contaminants, sampling periods shorter than a full workshift are required in order to sample within the recommended capacity of the monitor. Under these circumstances, sequential sampling with several monitors can be performed. 3520 For those compounds where the recommended length of the sampling period for the Organic Vapor Monitor 3500/3510 is less than a full workshift, the length of the sampling period can be increased by a factor of four when using the 3520 Organic Vapor Monitor. 1 3H 005246 2. Effect of Humidity Recommended sampling periods have been tabulated for concentration ranges from 0.1 to 0.5 times the PEL and from 0.5 to 3 times the PEL for relative humidities less than or greater than 70%. These recommended sampling periods should not be exceeded when using OVM 3500/3510. 3. Minimum Sampling Time To confirm quantitatively the presence and concentration of a contaminant in the atmosphere, most analysts must have a minimum of 10 micrograms for G.C. analysis. A sampling period of at least 15 minutes is recommended even when 10 micrograms of the contaminant could be collected in a shorter period. For a contaminant at a low concentration level, the sampling rate of micrograms/ppm-hr. should be used to verify a sampling period during which at least 10 micrograms of the contaminant would be collected. D. Short Term Exposure Limit (STEL) The ACGIH has recommended a short-term exposure limit (STEL) as a maximum concentration to which workers can be exposed for a period up to 15 minutes continuously. No more than four (4) such excursions per day are permitted, with at least 60 minutes between exposure periods, provided that the recommended ACGIH daily TLV-TWA also is not exceeded. The STEL values summarized in the following tables can be found in the "Threshold Limit Values for Chemical Substances in Workroom Air Adopted by ACGIH for 1980." The monitor is recommended for STEL sampling if, during the 15 minute sampling period, the monitor will collect a minimum of 10 micrograms of the contaminant when sampling at the STEL concentrations. E. Unsuitable Compounds The OVM is not recommended for the compounds listed below because of adverse or inadequate interactions with the sorbent material. This list is representative of classes of compounds not suitable for use with the OVM. Compounds not on this list or the Compound Guide should be handled by consultation with OH&SP Technical Service.

The table is not exhaustive and will be updated periodically. To obtain periodic updates, return the registration card contained in every box of monitors to 3M Company. A. OSHA Standards The OSHA TWA-PEL's (Time Weighted Average) given as workshift time weighted averages are taken from the Federal Register as found in 29 CRF 1910.1000 as of 1 January 1977 and are summarized in the "NIOSH/OSHA Pocket Guide to Chemical Hazards." Also included in parentheses are the current ACGIH (American Conference of Governmental Industrial Hygienist) values in cases where they differ from OSHA TWA's. These values are subject to change and appropriate publications should be consulted for the most current information. B. Monitor Samples Information * Sampling Rate All sampling rates have an accuracy of + 5%. The (*) compounds in the Sampling Guide tables have been subjected to an extensive amount of laboratory work to verify the sampling rate. The sampling rates given for the remaining compounds in this table were determined from empirical relationships as outlines in a publication on Sampling Rate Validation. The sampling rates are tabulated as cubic centimeters/minute and micrograms/ppm-hour. The publication on Sampling Rate Validation Protocol can be obtained upon request from 3M Company. The top section of the #3520 (containing the primary absorbent) has the same geometric dimension as the 3M Organic Vapor Monitor #3500. Therefore, the sampling rates are the same, and also have an accuracy of 5%. * Capacity The capacity of the monitor for each individual compound is a function of molecular structure, vapor pressure, environmental conditions, etc. The capacity values are tabulated in Section II - Analysis Guide, and are used to determine the length of a recommended sampling period. Because of the backup section, the effective sampling capacity of the Organic Vapor Monitor #3520 is four times greater than the values listed for the Organic Vapor Monitor #3500/3510. When sampling environments containing contaminant mixtures on environments with high relative humidity, it is difficult to accurately define the diffusional sampling capacity. Therefore, under these conditions, the weight (Ws) collected by the secondary absorbent of the backup section can be compared with the weight (Wp) collected by the primary absorbent to determine sample validity. The ration Ws/Wp must be equal to or less than 0.50. C. Length of Sampling Period 1. General 3500/3510 When sampling for organic contaminants, full workshift sampling periods are recommended as the most comprehensive measures of worker exposure. When sampling some organic contaminants, sampling periods shorter than a full workshift are required in order to sample within the recommended capacity of the monitor. Under these circumstances, sequential sampling with several monitors can be performed. 3520 For those compounds where the recommended length of the sampling period for the Organic Vapor Monitor 3500/3510 is less than a full workshift, the length of the sampling period can be increased by a factor of four when using the Organic Vapor Monitor #3520. Because of the increased effective capacity of the Organic Vapor Monitor #3520, sampling periods longer than a full workshift are possible. The preferred recommendation is for full workshift sampling periods. 1 3M 005253 2. Effect on Humidity Recommended sampling periods have been tabulated for concentration ranges from .1 to .5 times the PEL and from .5 to 3 times the PEL for relative humidities less than or greater than 70%. These recommended sampling periods should not be exceeded when using OVM #3500/3510. 3. Minimum Sampling Time To confirm quantitatively the presence and concentration of a contaminant in the atmosphere, most analysts must have a minimum of 10 micrograms for G.C. analysis. A sampling period of at least 15 minutes is recommended even when 10 micrograms of the contaminant could be collected in a shorter period. For a contaminant at a low concentration level, the sampling rate of micrograms/ppm-hr. should be used to verify a sampling period during which at least 10 micrograms of the contaminant would be collected. D. Short Term Exposure Limit (STEL) The ACGIH has recommended a short-term exposure limit (STEL) as a maximum concentration to which workers can be exposed for a period up to 15 minutes continuously. No more than four (4) such excursions per day are permitted, with at least 60 minutes between exposure periods, provided that the recommended ACGIH daily TLV-TWA also is not exceeded. The STEL values summarized in the following tables can be found in the "Threshold Limit Values for Chemical Substances in Workroom Air Adopted by ACGIH for 1980." The monitor is recommended for STEL sampling if, during the 15 minute sampling period, the monitor will collect a minimum of 10 micorgrams of the contaminant when sampling at the STEL concentrations. E Unsuitable Compounds The OVM is not recommended for the compounds listed below because of adverse or inadequate interactions with the sorbent material. This list is representative of classes of.compounds not suitable for use with the OVM. Compounds not on this list or the Compound Guide should be handled by consultation with OH&SP Technical Service.

The table is not exhaustive and will be updated periodically. To obtain periodic updates, return the registration card contained in every box of monitors to 3M Company. A. OSHA Standards The OSHA TWA-PEL's (Time Weighted Average) given as workshift time weighted averages are taken from the Federal Register as found in 29 CFR 1910.1000 as of 1 January 1977 and are summarized in the "NIOSH/OSHA Pocket Guide to Chemical Hazards." Also included in parentheses are the current ACGIH (American Conference of Governmental Industrial Hygienist) values in cases where they differ from OSHA TWA's. These values are subject to change and appropriate publications should be consulted for the most current information. B. Monitor Sampling Information Sampling Rate All sampling rates have an accuracy of 5%. The (*) compounds in the Sampling Guide tables have been subjected to an extensive amount of laboratory work to verify the sampling rate. The sampling rates given for the remaining compounds in this table were determined from empirical relationships as outlined in a publication on Sampling Rate Validation. The sampling rates are tabulated as cubic centimeters/minute and micrograms/ ppm-hour. The publication on Sampling Rate Validation Protocol can be obtained upon request from 3M Company. Capacity The capacity of the monitor for each individual compound is a function of molecular structure, vapor pressure, environmental conditions, etc. The capacity values are tabulated in Section II -- Analysis Guide, and are used to determine the length of a recommended sampling period. C. Length of Sampling Period When sampling for organic contaminants, full workshift sampling periods are recommended as the most comprehensive measure of worker exposure. When sampling some organic contaminants, sampling periods shorter than a full workshift are required in order to sample within the recommended capacity of the monitor. Under these circumstances, sequential sampling with several monitors is recommended. Recommended sampling periods have been tabulated for concentration ranges from .1 to .5 times the PEL and from .5 to 3 times the PEL for relative humidities less than or greater than 70%. These recommended sampling periods should not be exceeded. To confirm quantitatively the presence and concentration of a contaminant in the atmosphere, most analysts must have a minimum of 10 micrograms for G.C. analysis. A sampling period of at least 15 minutes is recommended even when 10 micrograms of the contaminant could be collected in a shorter period. For a contaminant at a low concentra tion level, the sampling rate of micrograms/ppm-hr. should be used to verify a sampling period during which at least 10 micrograms of the contaminant would be collected. 3M 005259 1 D. Short Term Exposure Limit (STEL) The ACGIH has recommended a short-term exposure limit (STEL) as a maximum concentra tion to which workers can be exposed for a period up to 15 minutes continuously. No more than four (4) such excursions per day are permitted, with at least 60 minutes between exposure periods, provided that the recommended ACGIH daily TLV-TWA also is not exceeded. The STEL values summarized in the following tables can be found in the "Threshold Limit Values for Chemical Substances in Workroom Air Adopted by ACGIH for 1980." The monitor is recommended for STEL sampling if, during the 15 minute sampling period, the monitor will collect a minimum of 10 micrograms of the contaminant when sampling at the STEL concentrations. E. Unsuitable Compounds The OVM is not recommended for the compounds listed below because of adverse or inadequate interactions with the sorbent material. This list is representative of classes of compounds not suitable for use with the OVM. Compounds not on this list or the Compound Guide should be handled by consultation with OH&SP Technical Service. Compounds Ammonia Carbon Monoxide Ethylene Oxide Formaldehyde Hydrogen Sulfide Isocyanates Methane, Ethane, Propane Methyl Alcohol (Methanol) Methyl Chloride Methyl, Dimethyl, Trimethyl Amines Organic Solids Sulfur Dioxide * All Compounds listed in bold type in the 3500 Sampling Guide will be analyzed by the 3M Specialty Analysis Service.
