Longwall Respirable Dust Simulator
ROBERT A. HANEY Mine Safety and Health Administration, Pittsburgh Health Technology Center The effectiveness of these dust control techniques has been evaluated primarily through the use of instantaneous dust measurements. These instantaneous dust measurements give a relative indication of whether dust control and -------------------~ employee exposure improve or deteriorate. Because the instan...
متن کاملRespirable Silica Dust Suppression During Artificial Stone Countertop Cutting
PURPOSE To assess the relative efficacy of three types of controls in reducing respirable silica exposure during artificial stone countertop cutting with a handheld circular saw. APPROACH A handheld worm drive circular saw equipped with a diamond segmented blade was fitted with water supply to wet the blade as is typical. The normal wetted-blade condition was compared to (i) wetted-blade plus...
متن کاملPhysicochemical properties of respirable-size lunar dust
We separated the respirable dust and other size fractions from Apollo 14 bulk sample 14003,96 in a dry nitrogen environment. While our toxicology team performed in vivo and in vitro experiments with the respirable fraction, we studied the size distribution and shape, chemistry, mineralogy, spectroscopy, iron content and magnetic resonance of various size fractions. These represent the finest-gr...
متن کاملEquivalency of a personal dust monitor to the current United States coal mine respirable dust sampler.
The United States National Institute for Occupational Safety and Health, through an informal partnership with industry, labor, and the United States Mine Safety and Health Administration, has developed and tested a new instrument known as the Personal Dust Monitor (PDM). The new dust monitor is an integral part of the cap lamp that coal miners normally carry to work and provides continuous info...
متن کاملDry separation of respirable lunar dust: Providing samples for the lunar airborne dust toxicity advisory group
In order to study the toxicity of lunar dust, the respirable size fraction of lunar soil needed to be separated with an apparatus that possesses the following capabilities: no use of liquid; fully recoverable sample; and use of only small sample quantities (o1 gm). We report the design of a simple apparatus that meets these requirements and implements an inertial-impaction mechanism established...
