What is 3M Organic Vapor Monitor?
The 3M Organic Vapor Monitor is a sampling device designed to measure average concentrations of certain contaminants over a measured time interval. It can be used for either personal or area monitoring. As a personal monitor, it is worn near the breathing zone of individuals exposed to potentially hazardous environment. When used as an area monitor, hang it away from walls, corners, table tops, or other regions where the air movement in the room may be limited.
3M Organic Vapor Monitor comes with single and double charcoal adsorbent pad. This monitor is designed to be analyzed by the user or by an independent laboratory. It is also available as a prepaid analysis for up to three compounds per monitor.
Why it is Needed?
Most countries have occupational exposure limits (OEL) for chemical substances in the workplace. In the United States the ACGIH Threshold Limit Values (TLV) and the OSHA Permissible Exposure Limit (PEL) standards are the most cited contaminant airborne standards.
TLVs are guidelines and are not legal standards in the U.S. but are legally enforceable in some countries. They are reviewed on a periodic basis and changed or reviewed if sufficient data warrants. There are three categories of TLVS: Threshold Limit Value-Time Weighted Average (TLV-TWA); Threshold Limit Value-Short Term Exposure Limit (TLV-STEL) and Threshold Limit Value-Ceiling (TLV-C).
The OSHA standards (PELs) can be found in Federal Register 29 CFR 1910 and are legally enforceable standards in the U.S. OSHA PELs have the same three categories as TLVS.
The 3M organic vapor monitors can be used to sample 8 hour TLV-TWAs and PELs. The organic vapor monitors can also be used to sample TLV-STELs and PEL-STELs if during the 15 minutes sampling period, the monitor is able to collect a sufficient quantity of contaminant for analysis. The organic vapor monitor is generally not recommended for sampling periods less than 15 minutes.
