Hazardous location classifications are essential for identifying environments where flammable gases, vapors, or combustible dusts may be present. These areas are classified into different zones to ensure proper safety measures and equipment are used, preventing potential hazards like explosions or fires. Classifications help guide the selection of electrical systems and devices designed to operate safely in these environments. Understanding hazardous location classifications is crucial for industries such as oil, gas, chemicals, and manufacturing to maintain safety standards and protect personnel and property.
