I'll take a go at this.
IATA publishes a very comprehensive manual relative to the transportation of dangerous goods. It's about two and a half inches thick, and gives a very detailed description of what is permitted on board a passenger aircraft, what is permitted on an all-cargo aircraft, and how it's to be packaged. It provides all of the technical and scientific details specific to the product that's permitted to be transported based on the rules of transportation.
That publication is used as a training program for our employees. Some of our employees are in the field of accepting the dangerous good. Others are in the field of handling that dangerous good, in terms of boarding the dangerous good on board an aircraft, and others, in terms of responding, should there be an event associated with that good.... Depending on the role of the employee, they are provided comprehensive training that is reviewed by Transport Canada. They not only review the program, but they will often sit in and actually observe the training sessions. That manual is used to describe.... I'll give you an example.
Radioactive isotopes that are used in the medical industry are routinely shipped to various research centres and hospitals across the country and across the world. Sometimes radioactive items can only be placed in some very specific areas of an aircraft cargo compartment. Our loading instructions detail to the employees where they're placed, how far away from the passenger, and how they're handled. They are labelled. They are documented. The flight crew know they're being carried on board. Further, flight crew have on board the aircraft a very detailed protocol on how to respond should there be an incident involving that dangerous good. It's a checklist that the flight crew use.
Across the spectrum, depending on the role and responsibility of the employee, there's exhaustive training that is conducted.
