What do passengers receive before boarding regarding hazardous materials?

Passengers receive notices and warnings before boarding concerning hazardous materials to ensure their safety during travel. This is an important safety protocol that aims to inform passengers about any potential dangers associated with certain materials that may be on board the aircraft. The notices typically outline restrictions on transporting hazardous items and provide essential information about what substances are deemed unsafe in the aircraft environment. By receiving these pre-boarding notifications, passengers are better equipped to understand safety regulations and avoid carrying prohibited items, thus contributing to a safer travel experience for everyone aboard.
