TSI's Kevin Chase has written a new feature article on confined spaces safety for Australian Mining magazine. The article, Personal exposure monitoring in confined spaces, was published in their December 17, 2019 issue. In it, Chase explains respirable particles and the dangers they pose to workers in confined spaces.
"Airborne dust and particulates are often made up of hazardous materials such as hexavalent chromium, lead, manganese, iron oxides, nickel, cadmium, silica, diesel particulate matter and other materials," he writes. These particles are identified by size (in microns), and are referred to as 'particulate matter,' as in PM10, PM4, PM2.5, and PM1.
Mining poses a special danger to workers because of "potentially volatile or explosive environments where gases, fuels or other potentially combustible materials are likely to be present," a problem exacerbated by the challenges of adequately ventilating confined spaces like underground mines.
TSI's intrinsically safe SidePak AM520i personal exposure monitor
In 2017 Queensland invited TSI to participate in an initiative that led to the development of a new intrinsically safe personal exposure monitor, created especially for confined spaces and/or explosive environments. TSI holds intrinsic safety certifications for the SidePak AM520i from the U.S., Canada, Europe, and Australia.
