In Bird's Accident Sequence model, which factor represents an immediate cause of an incident?

In Bird's Accident Sequence model, unsafe acts are identified as immediate causes of incidents. This model emphasizes that these unsafe actions carried out by individuals can trigger accidents directly. By focusing on unsafe behaviors, the model highlights the importance of recognizing and addressing these actions to prevent accidents from occurring in the first place.

The distinction is key because while basic causes, like systemic issues or environmental factors, are critical for understanding the root of safety problems, they do not directly result in an incident. Similarly, the concept of lack of control pertains to broader organizational or systemic failures that create conditions for unsafe acts to occur but are not the immediate trigger of the incident itself. Hence, unsafe acts stand out as the most direct and immediate causes of accidents within Bird’s framework, making them pivotal for accident prevention strategies.
