Why airlines are prohibited from transporting devices and devices containing mercury.

For security reasons. Airlines weigh all the risks when transporting dangerous goods. Having free mercury on an airplane is dangerous for several reasons. First, it is the health of employees and passengers. Mercury actively evaporates from the surface of the drop, polluting the air around it. At an altitude of 12,000 km, in a confined space, exceeding the MPC for mercury can seriously damage human health. Secondly, mercury is capable of interacting with other metals to form alloys – amalgams. In turn, amalgam has completely different mechanical characteristics than the starting material. Therefore, mercury can serve as a source of premature fatigue of materials and, as a result, their incapacitation.
