How can I measure workplace exposure to EnSolv?
We recommend using the ToxiRAE Plus PID meters manufactured by RAE Systems, preferably with data logging capability. We own 5 of these units and will lend them to any customer that requests one at no cost for safety and workplace exposure testing. These PID meters are the most accurate means of determining an 8-hour Time Weighted Average of Exposure and can help pinpoint where peak exposures occur, thereby allowing workers to determine how to reduce their exposure to EnSolv. Other acceptable, though less precise, means of measurement include badges such as the X541-1AT Organic Vapor Monitor badges by Assay Technology. These can be purchased in packages of 3 or more badges per box and include prepaid lab analysis by GC-FID. The downside of these types of monitoring devices is that they are not specific for nPB. TheToxiRAE Plus PID meters are calibrated for n-propyl bromide and are therefore far more accurate.
