Hazardous Areas Classification and Electrical Installations

Hazardous Areas Classification and Electrical Installations
• Hazardous areas are categorized into Zones based on risk level: Zone 0 (continuous explosive atmosphere), Zone 1 (likely to occur in normal operation), and Zone 2 (not likely to occur).
• Electrical installations in hazardous areas should be minimized, but a code of practice has been developed for specific equipment selection and protection.
• Methods to prevent electrical apparatus from igniting include Flameproof Enclosures, Increased Safety, Intrinsic Safety, Pressurized, Oil Immersion, Non-sparking and Restricted Breathing, and Special Protection.
