Why is safety training crucial for onboard service staff?

Safety training is essential for onboard service staff because it equips them with the necessary skills and knowledge to effectively handle emergencies that may arise during a flight. This training is not only about personal safety but also focuses on the safety of passengers, ensuring that all onboard can be protected in critical situations. Furthermore, it helps staff understand and comply with industry regulations, which are designed to safeguard both the crew and passengers. Maintaining a high standard of safety is central to the operations of any airline, as it fosters a safe travel environment and helps to build trust with passengers.

The other options neglect the broader importance of ongoing safety training regardless of staff tenure, aircraft condition, or job role, highlighting the comprehensive nature of safety protocols required in the aviation industry.
