Unruly passengers who exhibit disruptive or aggressive behavior can jeopardize the safety and security of the flight. Crew members are trained to de-escalate conflicts and, if necessary, restrain passengers who pose a threat. Cabin fires, while rare, can spread rapidly and pose a serious hazard. Fire extinguishers and emergency procedures are in place to combat cabin fires effectively. Rapid decompression, the sudden loss of cabin pressure, can occur due to structural damage or other factors. Oxygen masks are deployed automatically to provide supplemental oxygen to passengers and crew. Passenger briefings before takeoff cover emergency procedures, including the use of oxygen masks and evacuation procedures. Cabin emergencies highlight the importance of crew training and passenger awareness in maintaining a safe and secure flight environment.
