Air exposures to many VOC varied widely, sometimes over three orders of magnitude, among students on the same campus who had been monitored over the same time period and day. The personal monitor and spirometer proved feasible for collecting abundant quantitative data on most of the 15 target organics. The equipment tested included a personal monitor employing Tenax GC® to collect organic vapors for later analysis by GC-MS, and a specially designed spirometer for collecting samples of expired human breath on duplicate Tenax cartridges. Read on to find out how an Industrial Hygienist introduced Real-Time Monitoring into his Company and view the video here.Methods for determining individual exposure to volatile organic compounds (VOC) during normal daily activities were field tested on university student volunteers in Texas and North Carolina. Using the AM520 in real-time mode to implement control changes on the fly and using sampling pumps to collect gravimetric samples to meet compliance (ensuring the worker exposure is below the Permissible Exposure Limit), both instruments complement each other to maximise efficiency for the company.
Real-time monitoring instruments can help the Industrial Hygienist determine if a worker should put on a respirator during the operation instantaneously. This eliminates the need to wait for the laboratory results from a sampling pump. This is especially important for Industrial Hygienists working in the hazardous environment known to contain flammable gasses, vapours, dust etc. It also allows corrective actions to be implemented real-time as compared to gravimetric sampling which needs a long wait for laboratory test results, typically a week later. This can be used for making decisions on the fly for workers over exposing to dust and other suspended particulates. The SidePak not only provides real-time data, it also enables users to analyse time history data. This is the first intrinsically safe real-time personal aerosol monitor introduced in the market. The introduction of real-time photometer with intrinsic safety rating, SidePak™ AM520i Personal Aerosol Monitor, allows for application in the hazardous environment. This monitor is the perfect solution for real-time personal aerosol sampling in a variety of workplace environments including but not limited to general industry, foundries, construction sites, chemical plants, refineries, petrochemical, power stations, automotive, aerospace, marine time, confined space works and mining.
The SidePak™ AM520 / AM520i Personal Aerosol Monitor is a small, portable, battery-operated, data-logging, light-scattering laser photometer that provides real-time aerosol mass concentration readings of dusts, fumes, mists, smoke and fog within a worker breathing zone. We will sum up all the valuable information on how SidePak™ AM520 / AM520i Personal Aerosol Monitor can help them quantify the dust level and effectively use it at the work place. The benefits are often overlooked as the real-time personal photometric PM measurement is not an official reference method. At times, an Industrial Hygienist may not be aware how they can effectively use a real-time Personal Aerosol Monitor at the workplace.
