What is the HFACS level that refers to unsafe supervision?

The correct choice regarding the HFACS (Human Factors Analysis and Classification System) level that refers to unsafe supervision is indeed the one associated with Level 3. This level specifically addresses the failures in the supervisory role that can lead to unsafe practices or conditions within a team or organization.

Unsafe supervision encapsulates several aspects, including inadequate supervision, failure to provide proper guidance, or neglecting to ensure that individuals are adhering to established policies and procedures. These failures can directly impact the safety of operations, as supervisors are instrumental in establishing and enforcing safety standards and expectations.

In HFACS, this classification is crucial because it helps to pinpoint where the breakdowns occur in the hierarchy of safety management, especially in environments like firefighting, where oversight is essential for operational safety. The focus on level three integrates the recognition that while individual actions are important, the role of supervision is equally vital for fostering a culture of safety and accountability.
