Applications
1. Petroleum and Chemical Industry
Locations: Refineries, chemical plants, drilling platforms, gas stations, and oil depots.
Hazardous Materials: Flammable and explosive gases and vapors such as crude oil, natural gas, gasoline, benzene, and alcohols.
2. Coal Mining Industry
Locations: Underground tunnels, mining faces, and transfer stations.
Hazardous Materials: Gas (primarily methane) and coal dust.
3. Dust Explosion Atmospheres
Locations: Flour mills, sugar refineries, feed processing plants, metalworking plants (aluminum and magnesium powders), wood processing plants, and plastics plants.
Hazardous Materials: Combustible dust suspended in the air.
4. Pharmaceutical and Food Industry
Locations: Some raw material workshops, ethanol extraction plants, and starch or sugar powder processing areas.
Hazardous Materials: Alcohol vapors and combustible dust.
5. Other Industrial Sites
Locations: Paint spraying plants (solvent vapors), solvent warehouses, gas boiler rooms, and sewage treatment plants (may generate methane).
Hazardous materials: Various flammable and explosive chemicals.
Simply put, if a location is classified as an "explosive atmosphere" and has been clearly divided into explosion-hazardous zones (e.g., Zone 0, Zone 1, Zone 2; Zone 20, Zone 21, Zone 22) according to national standards (such as China's GB3836), then all electrical equipment within that area, including lighting, must use explosion-proof products of the corresponding explosion-proof grade and type.
Key keywords: flammable gases, flammable vapors, combustible dusts, and flammable fibers. Whenever these substances may be present in the work environment, the use of explosion-proof electrical equipment must be prioritized to ensure the safety of life and property.
The Importance of Using Explosion-Proof Products
1. Complying with International Regulations and Avoiding Legal Risks
Strict Global Regulation:
EU: The ATEX Directive (2014/34/EU) mandates the use of explosion-proof equipment in high-risk areas. USA: NEC (National Electrical Code) 500-506 Zone Divisions, OSHA regulated.
China: GB 3836-2010 Explosion-Proof Standards, Coal Mine Safety Regulations (AQ Standards).
Violation Penalties: Companies that fail to use compliant explosion-proof products may face heavy fines, production suspensions, and even criminal prosecution.
2. Improve Production Efficiency and Reduce Maintenance Costs
Explosion-proof LED Luminaires: Save 60% more energy than traditional explosion-proof metal halide lamps, with a lifespan of up to 50,000 hours, reducing replacement frequency.
Intelligent Explosion-Proof Systems: Integrated sensors and remote monitoring improve safety management efficiency.
Reduced Maintenance Downtime: Explosion-proof products are corrosion-resistant and vibration-resistant, suitable for harsh environments and reducing failure rates.
3. Adapt to Extreme Environments, Ensure Reliable Operation
Explosion-proof products are designed for harsh operating conditions and feature:
High/Low Temperature Resistance (-60°C to +80°C, suitable for Arctic oil fields or desert refineries).
Waterproof and Dustproof (IP66/IP68, suitable for offshore platforms or wet mines). Corrosion-resistant (316 stainless steel or special coating to resist chemical corrosive gases).
