3M Organic Vapor Monitor Sampling Guide May, 1981 ANOTHER STEP TOWARDS BETTER OCCUPATIONAL HEALTH AND SAFETY r-35sg<qii.)R Occupational Health and Safety Products Division/3M 220-7W 3M Center St. Paul, MN 55144 3M 005702 Lithe In U.S.A. 3M Organic Vapor Monitor Sampling Guide 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 #3500 Organic Vapor Monitor can be used to accurately determine the environmental exposures. 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 Rata 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 mlcrograms/ 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 mlcrograms 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 005703 1 D. Sh rt 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.
