![]() ![]() Safety professionals know that there can be a great difference in gas concentrations between the waist and the nose/mouth area of the workers face. The sampler is designed to collect the agent ofinterest and may have activated charcoal or gel-covered. Personal sampling is a method of sample collection whereby the dust sample collected is in the breathing zone of a mine worker while performing occupational duties during a work shift. near the workers breathing zone around the face. Recommended applications for personal air sampling in NRC licensee radiation protection programs are presented. That’s why workers should always wear their portable gas detectors in what’s known as the breathing zone, such as the lapel, shirt collar, or chest pocket. Personal sample area sample breathing zone portable# The recommendations are based on performance tests of currently available samplers, a review of research and regulatory literature, and a survey of current licensee air-sampling programs. The performance tests show that personal air samplers are available which can provide a reliable, convenient means for breathing-zone sampling of workers in practically any work environment which might be encountered in the licensee industries. The research literature emphasized that estimates of an individual's exposure may be greatly underestimated if based on general area air samples, as is common practice in current licensee programs, due to the unpredictable variability of airborne-activity concentrations in the worksite. Personal sampling tubes, driven by a belt-mounted sampling pump, can also sample within the breathing zone, but are less cost-effective and less convenient. Seven personal breathing zone (PBZ) air samples, and one area air sample were collected from approximately 7:30 to 11:30 on the morning of August 4, 1992. Research concerning the applicability of air-sampling measurements for estimating intake, uptake, and internal dose was also reviewed. Sample collection and analysis was performed using a modification of NIOSH Method 1500. These studies indicate that although breathing-zone activity measurements might provide the best (although not always accurate) means to estimate intake, estimates of uptake and internal dose usually should be made with bioassay or whole body counting. Other information on practical aspects of personal air sampling and related exposure control efforts are presented in the report. Personal sample area sample breathing zone portable#.Munro offers a full range of accessories to complement the instrument, including filter holders, filters cyclones, asbestos heads, IOM heads and Arnold bubblers as well as specialised devices to fractionate the particulate. We offer single- and five-channel battery chargers. To reduce weight and improve battery life, we have incorporated nickel metal hydride batteries, which are more environmentally friendly than other types. The ABS enclosure ensures that the internal components are well protected against moisture, dust and chemical ingress. The AS200 incorporates an accurate elapsed time module with a LCD display. ![]() It has automatic electronic flow compensation to overcome the effects of back pressure and to ensure that flow is maintained within ±5% of the desired set point. The AS200 uses a diaphragm vacuum pump to ensure a smooth and reliable air flow. The AS200 Personal Air Sampler is small, lightweight and quiet. The sample should be collected during normal working activity. These air samplers are designed to be worn by the operator, with the sample head located in the breathing zone. The AS200 Personal Air Sampler can be used to assess occupational exposure to gases, vapours and dusts. ![]()
