Explosion Proof Extension Cord (Class I, Div 1)

The Explosion Proof Extension Cord (Class I, Div 1) is a purpose-built solution for hazardous work environments where standard extension cords pose a significant risk of triggering explosions. This specialized power cord is designed to safely deliver temporary power in areas with flammable gases, vapors, or dust (Class I Div 1 or Class II). With factory-sealed explosion-proof connectors, both the plug and receptacle are engineered to contain and extinguish sparks, preventing any chance of ignition in volatile surroundings.

For procurement managers in industries such as oil & gas, petrochemical, or mining, this cord offers a safe, compliant way to provide power to lighting, pumps, or tools in confined hazardous zones. Its durable construction and certified safety ratings make it a reliable choice in high-risk areas.

This extension cord features a rugged 12/3 or 10/3 SOOW flexible cable with a temperature-resistant jacket that can withstand extreme conditions, from -40°F in frigid outdoor rigs to 105°C (221°F) in high-temperature processing plants. The connectors, made from copper-free aluminum or brass, have a threaded design that ensures a flameproof seal when screwed together, preventing internal arcing or heat from igniting the surrounding atmosphere. A locking screw ring secures the connection, adding extra stability in vibration-prone environments.

Explosion-proof extension cords are a game-changer for refineries, grain processing plants, and other hazardous locations. They allow workers to safely operate portable lights, ventilation fans, and sensors inside tanks and reactors, all while adhering to OSHA and NEC regulations that require explosion-proof or low voltage equipment. The cord’s black oil-resistant jacket and heavy-duty strain reliefs add to its durability and long-lasting performance in industrial settings.

Each cord undergoes rigorous testing and typically carries UL Standard 1203 or CSA C22.2 certification, ensuring it meets the highest safety standards for hazardous locations. In summary, the Class I Div 1 Explosion Proof Extension Cord provides safe, reliable power in explosive environments, enabling maintenance and operations teams to work confidently and efficiently, no matter how dangerous the conditions.
