3M Organic Vapor Monitor Sampling Guide For Organic Vapor Monitor #3500/3510 Organic Vapor Monitor With Back-Up Section #3520/3530 January 1992 70-0701-1274-6 (121 5) R2 CFO 260A. 282A 3M Occupational Health and Environmental Safety Division 3M Center Bldg. 275-6W-01 St. Paul, Minnesota 55144-1000 3H 105594 LithO in U.S.A. Use of the Sampling Guide Tables: The following table summarizes OSHA standards, 3M monitor sampling information, and recommended sampling procedures for a variety of organic compounds for which the 3M Organic Vapor Monitors can be used to accurately determine the environmental exposures. The table is not exhaustive and will be updated periodically. A. OSHA Standards The OSHA TWA-PELs given as workshift time weighted averages, are taken from the code of Federal Regulations as found in 29 CFR 1910.1000 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 PEL 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 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. 3520/3530 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 3520/3530 Organic Vapor Monitor. 1 3M 105595 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 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. Compounds Ammonia Carbon Monixide Ethylene Oxide (1) Formaldehyde (2) Hydrogen Sulfide Isocyanates Methane, Ethane, Propane Methyl Alcohol (Methanol) Methyl Chloride Methyl, Dimethyl, Trimethyl Amines Organic Solids Sulfur Dioxide (1) Ethylene Oxide can be monitored using 3M 3550/3551 Ethylene Oxide Monitor (2) Formaldehyde can be monitored using 3M 3720/3721 Formaldehyde Monitor. F. 3M Analytical Service Selected compounds listed in the OVM Sampling Guide will be analyzed by 3M using the 3M 3510 or 3530 Monitor sold with a prepaid analysis.
