All goods deemed dangerous belong to one of how many different classes of dangerous goods?

Goods classified as dangerous are categorized into nine distinct classes. Each class addresses specific types of hazardous materials and outlines the protocols for handling, storing, and transporting them safely in various environments, including air travel.

For instance, Class 1 encompasses explosives, while Class 2 involves gases that can be flammable, non-flammable, or toxic. The other classes continue to specify a range of substances, such as flammable liquids, solids, oxidizers, toxic materials, and infectious substances, through to Class 7, which includes radioactive materials. Each class has its own regulations aimed at ensuring safety for passengers, crew, and the aircraft itself.

The classification into nine classes allows regulatory bodies and companies like Air Canada to develop tailored safety measures and training programs for flight attendants and other personnel involved in the transportation of these materials. This comprehensive system is essential for managing the risks associated with dangerous goods effectively during air travel.
