Final answer:
Transportation of irritant or incapacitating substances such as mace and pepper spray is typically not permitted on one's person or as carry-on luggage on commercial flights; they may be permitted in checked baggage under specific conditions. Regulations can vary, so it's important to check with airlines and authorities.
Step-by-step explanation:
The question pertains to the transportation of disabling devices such as mace and pepper spray in the context of air travel. Typically, there are strict regulations regarding the carriage of such substances on commercial flights due to safety and security concerns. Disabling devices containing irritant or incapacitating substances are generally prohibited on one's person or as carry-on baggage due to the potential risks they pose within the enclosed environment of an airplane. However, they may be allowed in checked baggage under specific conditions such as a safety mechanism and volume restrictions. It's crucial to check with the airline and relevant authorities as regulations can vary.
Military police and security personnel are often required to undergo exposure to pepper spray during their training. This experience aims to foster a sense of empathy and restraint when they might have to use such substances in the line of duty. Similarly, individuals who have undergone certain medical treatments may be advised that they could set off radiation detectors at airports, as noted by the LibreTexts™ system, and would need to obtain special permission to travel.
