What is the potential hazard in Class II locations?

In Class II locations, the primary potential hazard is the presence of combustible dust. This classification pertains to areas where dust may create a hazard due to accumulation or suspension in the air, which can ignite if exposed to an ignition source. Dust can come from various industrial processes and can settle on surfaces, leading to the risk of an explosion or fire if the dust is disturbed and enters a state where it can mix with air.

Understanding the nature of combustible dust is crucial for safety protocols in environments where such materials are handled or stored. In contrast, other materials such as flammable gases or combustible liquids are typically categorized under different classes, highlighting the specific risks associated with each type of hazardous material. The focus on combustible dust in Class II locations emphasizes the need for proper dust control measures, ventilation, and equipment designed to minimize ignition sources in areas where dust might accumulate.
