What is an explosive atmosphere?
An explosive atmosphere is defined as a mixture of dangerous substances with air, under atmospheric conditions, in the form of gases, vapours, mist or dust in which, after ignition has occurred, combustion spreads to the entire unburned mixture. Many workplaces may contain, or have activities that produce, explosive or potentially explosive atmospheres.
Examples include places where work activities create or release flammable gases or vapours, such as vehicle paint spraying, or in workplaces handling fine organic dusts such as grain flour or wood. Safe, reliable communication is a critical tool in such dangerous environments. That’s where the power and performance of MOTOTRBO ATEX intrinsically safe digital radios stand out.
