Multiple Choice

Dangerous goods forbidden to be carried by passengers include which of the following groups?

In aviation safety, some dangerous goods are completely forbidden for passengers because they pose a high risk in the confined environment of a cabin. The group listed here includes items that are not allowed on passenger aircraft due to their inherent hazards. Liquid oxygen devices contain compressed oxygen, which is an oxidizer and can create dangerous fires or explosions in flight; they must be handled as cargo under strict rules instead of being carried by passengers. Electroshock weapons are weapons designed to deliver a harmful electric shock, so they’re not permitted on board for security reasons. Pepper spray is a pressurized irritant with hazardous contents that cannot be carried by passengers. Lithium ion batteries carry a real fire risk if damaged or short-circuited; while some batteries are allowed under specific conditions, many spare or certain larger batteries fall under prohibitions for passenger carriage. Other options can be allowed under particular regulations (with limits or documentation), which is why they aren’t universally forbidden.
