Annex 18 deals with the "Safe Transport of Dangerous Goods by Air". In general it sets down broad principles but one of the Standards requires that dangerous goods are carried in accordance with the Technical Instructions for the Safe Transport of Dangerous Goods by Air (the “Technical Instructions”). States are required by Annex 18 to have inspection and enforcement procedures to ensure that dangerous goods are being carried in compliance with the requirements.
Dangerous goods are carried regularly and routinely by air all over the world. To ensure they do not put an aircraft and its occupants at risk there are international Standards which each State, under the provisions of the Chicago Convention, are required to introduce into national legislation. This system ensures governmental control over the carriage of dangerous goods by air and gives world-wide harmonization of safety standards.
