The aviation sector refers encompasses all activities related to the design, development, manufacturing, operation, and maintenance of aircraft, as well as the management of air transportation and aviation services.


  • Aircraft Manufacturers: companies like Boeing, Airbus, Bombardier, and Embraer design, manufacture, and assemble various types of aircraft, including commercial airliners, business jets, regional planes, and military aircraft
  • Airlines: operate scheduled and charter flights to transport passengers and cargo. Airlines own and maintain a fleet of aircraft and provide various services related to air travel
  • Airports: serve as the infrastructure where aircraft take off, land, and are serviced. They offer facilities for passengers, cargo, maintenance, and air traffic control
  • Air Traffic Control (ATC): ATC involves managing the movement of aircraft to ensure safe and efficient air travel. Air traffic controllers guide aircraft during takeoff, landing, and en-route, helping to prevent collisions and ensuring smooth operations
  • Aircraft Maintenance and Repair:  the maintenance, repair, and overhaul (MRO) of aircraft to ensure their safety and reliability. MRO companies provide services to airlines, aircraft owners, and other operators
  • Aviation Services: a wide range of services such as aircraft leasing, flight training, aviation consulting, aviation insurance, and ground handling services at airports
  • General Aviation: all non-commercial aviation activities, including private flying, recreational flying, flight schools, and small aircraft manufacturing
  • Military Aviation: governments and armed forces utilise aircraft for defence and national security purposes, including combat, reconnaissance, transportation, and search and rescue
  • Space Aviation: while distinct from traditional aviation, the space aviation sector focuses on the design, launch, and operation of spacecraft for various purposes, including satellite deployment, space exploration, and scientific research


The aviation sector plays a vital role in global transportation, trade, tourism, and national security. It has a significant economic impact and requires collaboration between various stakeholders, including regulatory bodies, industry associations, and technology providers, to ensure safe and efficient operations


In the aviation sector, there are several areas where potentially explosive atmospheres can be present due to the presence of flammable gases, vapours, or dust. These areas are classified as hazardous zones, and they require special precautions and equipment to ensure safety. The classification of hazardous zones is typically based on international standards such as the ATEX (ATmosphères EXplosibles) directives in Europe and similar regulations in other regions.


  • Aircraft Fuelling and Maintenance Areas: aircraft maintenance hangars, fueling stations, and areas where aircraft are fueled and defueled are potential hazardous zones. Flammable jet fuel and other chemicals used in aviation maintenance can create explosive atmospheres
  • Fuel Storage Facilities: storage areas for aviation fuels and other flammable liquids can generate potentially explosive atmospheres if proper ventilation and safety measures are not in place
  • Aviation Paint Shops: paint fumes and solvent vapors in aviation paint shops can create hazardous zones if they are not properly managed. Spray booths and other safety measures are employed to minimize the risk of explosions
  • Engine Test Stands: areas where aircraft engines are tested can contain flammable gases and exhaust fumes, which can lead to potentially explosive atmospheres if not controlled properly
  • Battery Charging Areas: charging areas for batteries can generate explosive atmospheres if there are hydrogen emissions during the charging process
  • Hangar Ventilation Systems: poorly designed or maintained ventilation systems in hangars can allow the buildup of flammable vapours, potentially leading to hazardous conditions.
  • Aircraft Cargo Holds: if hazardous materials or flammable cargo are not properly handled and stored, they could create potentially explosive atmospheres in aircraft cargo holds

It's important to note that regulations and safety standards vary from country to country, and aviation organizations must adhere to the appropriate regulations and guidelines to ensure the safety of personnel, equipment, and facilities. Preventive measures such as proper ventilation, grounding equipment, using intrinsically safe equipment, and conducting regular safety assessments are essential to mitigate the risks associated with potentially explosive atmospheres in the aviation sector
