What does the term "barrier management" refer to in aviation safety?

The term "barrier management" in aviation safety refers to identifying and establishing defenses against potential hazards. This approach recognizes that in any complex system, such as aviation, there are inherent risks that can lead to accidents or incidents. By focusing on barriers, safety management aims to create layers of protection that can prevent errors or mitigate their consequences.

Specifically, barrier management involves understanding various safety measures, procedures, and protocols that are in place to protect against failures. These barriers can include training programs, standard operating procedures, safety equipment, and communication protocols that enhance situational awareness and decision-making among crew members. The goal is to ensure that even if an error occurs, the existing barriers will either prevent an accident or reduce its severity.

In aviation, where safety is paramount, this proactive identification and enhancement of barriers is essential in cultivating a culture of safety and reliability. It underscores the importance of a systematic approach to risk management, where potential hazards are consistently monitored and managed through established defenses.
