There are some factors you need to take into account when you pack your bags. Items in your baggage can be affected by things like temperature, pressure and vibration.
Temperature can affect the contents of a package filled at low temperature. When the temperature increases, the package can expand in volume causing any liquid contents to leak, or burst packages with gaseous contents.
Pressure varies from normal at sea level, to a lesser pressure of about only 2/3 of that at sea level. Reduction in pressure can result in liquid and gaseous contents bursting out of their containers. This can be very messy and very dangerous.
Vibration experienced, not only by baggage, but the contents of the baggage, can result in a potentially dangerous situation. For example book matches and cigarette lighters subject to vibrations have been known to ignite while in suitcases, brief cases and even in pockets.
