TDG Training by Air


ICAO has released their newest version of the Technical Instructions.  As Air Training expires every 2 years it is important for companies to update their training as a number of changes have been made by the Air Industry relating to dangerous goods and their transportation.


ICAO – The International Civil Aviation Organization, is a collaborative effort of 193 countries to develop standards in aviation to ensure safe and sustainable air operations around the globe.  While they are not a regulatory agency, they provide International guidelines to transportation concerning dangerous goods in their Technical Instructions.  These instructions can then be used to provide regulatory training to those businesses shipping, handling or packaging dangerous goods using Air transport.  


Remember, your business cannot ship any regulated dangerous goods by Air without the proper training and certification.
