An "Explosive Atmosphere" refers to a mixture of air and flammable substances, such as gases, vapors, or dust, that can ignite and cause an explosion. This condition can occur in various environments, including industrial settings, where materials like gasoline or coal dust are present. Proper safety measures are essential to prevent ignition sources, such as sparks or open flames, from coming into contact with these mixtures. To manage the risks associated with explosive atmospheres, regulations and standards, such as those set by OSHA and ATEX, are implemented. These guidelines help ensure that workplaces are designed and maintained to minimize the likelihood of an explosion, protecting both workers and equipment from potential hazards.
