When it comes to natural gas pump and pressure stations, safety is paramount. These facilities handle highly flammable gases, making them potentially hazardous environments where even a small spark could lead to catastrophic explosions. To mitigate these risks, explosion proof lighting is essential. Understanding Explosion Proof Lighting Explosion proof lighting is specifically designed to prevent the ignition of flammable gases and vapors in hazardous environments. This type of lighting is constructed to contain any sparks or arcs that may occur within the fixture, preventing them from igniting surrounding gases. The key features of explosion proof lighting include robust enclosures, seals to prevent gas entry, and materials that can withstand harsh conditions. Standards for Natural Gas Pump and Pressure Stations Natural gas pump and pressure stations must adhere to several standards to ensure safety and compliance. Here are some of the key standards: National Fire Protection Association (NFPA) Standards: NFPA 70: National Electrical Code (NEC): This code outlines requirements for electrical installations in hazardous locations, including natural gas facilities. It defines areas classified as Class I, Division 1 or Division 2, where flammable gases or vapors are or may be present. NFPA 30: Flammable and Combustible Liquids Code: Provides guidelines for the safe storage and handling of flammable liquids, which is relevant when dealing with natural gas. Occupational Safety and Health Administration (OSHA): 29 CFR 1910.307: Hazardous (Classified) Locations: OSHA’s standard for electrical installations in hazardous areas aligns with the NEC, specifying safety requirements for equipment used in locations where flammable gases or vapors are present. Pipeline and Hazardous Materials Safety Administration (PHMSA): 49 CFR Part 192: Covers the transportation of natural gas by pipeline, including safety standards for associated facilities, such as pump and pressure stations. Lighting Certifications for Explosion Proof Environments For lighting fixtures to be used in natural gas pump and pressure stations, they must be certified for explosion proof use in accordance with specific standards. Here are some of the key certifications: Underwriters Laboratories (UL) Certifications: UL 844: Standard for Luminaires for Use in Hazardous (Classified) Locations: This certification applies to lighting fixtures designed for use in hazardous environments. UL 844 ensures that the lighting fixture will not ignite flammable gases or vapors if an internal explosion occurs. International Electrotechnical Commission (IEC) and ATEX Certifications: IEC 60079 Series: These international standards apply to equipment for explosive atmospheres. Lighting fixtures that comply with IEC 60079 are suitable for use in areas where flammable gases or dust may be present. ATEX Directive: In Europe, the ATEX certification (derived from the French “ATmosphères EXplosibles”) is required for equipment used in explosive environments. While not required in the U.S., ATEX certification is often recognized globally and can indicate a high level of safety. CSA Group (Canadian Standards Association): CSA C22.2 No. 137: This Canadian standard specifies requirements for explosion-proof luminaires for use in hazardous locations, similar to UL 844 in the United States. GRINSAFE Certified explosion proof lighting is a critical safety feature for natural gas pump and pressure stations. Features of GRINSAFE explosion proof certified lighting fixtures are: Class I & II， Division 1 & 2 listed Up to 170lm/W, reducing energy costs High output up to 64,000lm IP66 / IP67 ingress protection UL1598A marine outside type and corrosion resistant LED rated life > 150,000 hours at 25°C ambient By adhering to the certifications and features, facilities can ensure that their lighting is both safe and compliant, reducing the risk of explosions and ensuring the safety of personnel and equipment. By investing in certified explosion proof lighting, operators of natural gas facilities can protect their assets and personnel, while also ensuring compliance with safety regulations.
