What is the primary safety equipment required on commercial flights?

The primary safety equipment required on commercial flights includes life vests, oxygen masks, and emergency exit slides, which are crucial for ensuring passenger safety in various emergency scenarios. Life vests are essential for over-water flights, as they provide flotation assistance in the event of a water landing. Oxygen masks are vital for maintaining oxygen supply in case of cabin depressurization, allowing passengers and crew to breathe until the aircraft descends to a safer altitude. Emergency exit slides facilitate a rapid escape from the aircraft, especially in emergencies involving fire or smoke on board, allowing for a swift evacuation. This combination of equipment is regulated by aviation authorities globally and is integral to the safety protocols within the aviation industry.
