Aircraft hangars and aviation MRO facilities demand more than high-output industrial lighting. Aircraft maintenance can involve fuel, lubricants, solvents, paint, welding, hot work, and other operations that may create challenging or potentially hazardous environments. In these areas, lighting must provide reliable illumination while also meeting the electrical, environmental, and hazardous-location requirements of the specific installation. GRINSAFE provides a range of hazardous location and heavy-duty industrial LED lighting solutions designed for demanding applications, from aircraft hangars and maintenance facilities to fueling areas, paint operations, and service pits. Where Is Hazardous Location Lighting Needed in Aviation? Not every area of an airport or aircraft hangar requires explosion-proof lighting. The correct fixture depends on the specific operation, hazardous-area classification, ventilation, fuel or chemical exposure, and applicable local codes. Typical aviation areas where hazardous-location or enclosed industrial lighting may be considered include: Aircraft hangars and servicing areas Aircraft fueling and fuel-handling areas Aircraft maintenance and MRO facilities Landing gear pits, ducts, and tunnels Aircraft paint and coating areas Engine and fuel-system maintenance areas Maintenance workshops and support areas Outdoor aircraft service and equipment areas For example, NFPA 409 addresses electrical systems in aircraft hangars and specifically identifies areas such as landing gear pits and tunnels as environments where flammable liquids and vapors may be present. Paint hangars also require appropriately enclosed lighting fixtures. Key Lighting Requirements for Aircraft Hangars & MRO Hazardous Location Protection Where flammable vapors or combustible materials may be present, lighting equipment must be suitable for the applicable hazardous location classification. Depending on the project, this can include Class I Division 1, Class I Division 2, or Zone-rated equipment. The classification should always be determined by the project engineer or authority having jurisdiction. GRINSAFE offers UL844 hazardous-location LED fixtures for applications requiring certified protection against ignition hazards. High-Efficiency Illumination Aircraft hangars can have significant ceiling heights and large floor areas. High-efficiency LED lighting helps deliver the required illumination while reducing energy consumption and maintenance requirements. GRINSAFE products such as the GHRL, GHSM, GHLW, and GHLV families provide high-output LED solutions for different mounting heights and application requirements. Uniform Lighting With Reduced Glare Aircraft maintenance requires technicians to inspect surfaces, components, wiring, engines, and aircraft structures. Poorly distributed light can create shadows beneath wings, fuselage sections, and equipment. FAA research on human factors in aviation maintenance has highlighted the importance of controlling glare and designing lighting to provide a uniform visual environment, particularly around aircraft surfaces where shadows can occur. For this reason, aircraft maintenance lighting should consider not only lumen output, but also fixture distribution, mounting position, beam pattern, color quality, and glare control. Resistance to Impact, Vibration, and Harsh Environments Aircraft hangars are active industrial environments. Lighting fixtures may be exposed to vibration, accidental impact, dust, moisture, oils, cleaning chemicals, and temperature changes. Durable housings, impact-resistant lenses, high IP ratings, and corrosion-resistant construction can help extend fixture life and reduce maintenance requirements. Emergency Lighting Maintenance facilities and aircraft hangars may also require emergency illumination for safe evacuation and continued visibility during power interruptions. GRINSAFE offers emergency lighting options across selected hazardous-location product families, including UL924-certified configurations and 90-minute battery backup options. GRINSAFE Lighting Solutions for Aviation Applications GRINSAFE offers a range of hazardous location and heavy-duty LED lighting solutions for different areas of aircraft hangars and aviation MRO facilities. GHSL & GHRL: High-output lighting for large hangars, maintenance bays, and service areas. GHLW & GHLV: Linear lighting for maintenance areas, workshops, and spaces requiring continuous illumination. GHE: Hazardous-location emergency exit and combination lighting for emergency egress. GHW: Compact lighting for walls, entrances, equipment areas, and other lower-mounting applications. Depending on the application, GRINSAFE fixtures are available with hazardous-location certifications, high-efficiency LED performance, durable construction, and emergency lighting options.

Aviation maintenance environments combine demanding lighting requirements with strict safety considerations. A suitable lighting system needs to balance hazardous-location protection, illumination performance, durability, energy efficiency, installation flexibility, and emergency requirements. GRINSAFE’s hazardous-location lighting portfolio allows different fixture types to be matched to different areas within the same aviation facility—from high-ceiling hangars and maintenance bays to service areas, pits, workshops, and emergency exits. Instead of selecting one fixture for the entire facility, project designers can build a more application-specific lighting system using different GRINSAFE product families according to the area’s classification, mounting height, illumination requirements, and environmental conditions.
