Refrigerating machines are essential in various industries, from food preservation to medical storage. However, regarding air transportation, these machines are subject to specific regulations to ensure safety. Under the United Nations (UN) classification, refrigerating machines containing non-flammable, non-toxic liquefied gases or ammonia solutions are categorized under UN2857. These machines are typically governed by Packing Instruction 211, which outlines the requirements for safe air transport. Special Provisions (IATA A26 / ICAO 119)
Refrigerating machines may qualify for exemptions under IATA Special Provision A26 (ICAO Special Provision 119) under specific conditions. These provisions apply when the machines meet the same requirements outlined in packing instruction 211 in the IATA DGR, such as cylinder capacity limits, safety device standards, and proper shut-off valve installation. This exemption permits the transport of refrigerating machines on both passenger and cargo aircraft, as well as cargo-only aircraft, as long as all safety measures are strictly followed.
Additionally, refrigerating machines and refrigerating machine components are not subject to these regulations if they contain less than 12 kg of a Division 2.2 gas or less than 12 liters of ammonia solution (UN 2672). This exemption simplifies the transportation process for smaller units, reducing regulatory burdens while maintaining safety standards.
FAQ Section
1. Is refrigerant considered hazardous?
Yes, refrigerants are classified as hazardous materials (hazmat) under UN2857 when they contain non-flammable, non-toxic liquefied gases or ammonia solutions.
2. Is a refrigerator hazmat?
Refrigerators themselves are not inherently hazardous to material. However, if they contain refrigerants classified as hazardous materials, they are subject to hazmat regulations during transport.
3. What type of hazard is a refrigerator?
Refrigerators containing refrigerants under UN2857 are classified as Division 2.2 hazards, which are non-flammable, non-toxic gases.
4. What hazard class is refrigerant?
Refrigerants under hazard classes 2.1 flammable gas, 2.2 non-flammable gas, 2.3 toxic gas, 8 corrosive
5. What shipping class is a refrigerator?
Refrigerators are typically classified under Freight Class 92.5 for shipping purposes. This classification is based on the type of commodity and its characteristics.
