Fire Entrapment occurs when an individual such as a firefighter places themselves in the direct line of a wildfire, often with fatal consequences. This can occur, for example, when firefighters misjudge crosswinds or fail to leave themselves alternate escape routes should the fire suddenly shift. The S-185 Fire Entrapment Avoidance course teaches trainees strategies to help avoid these situations.
The focus of the S-185 course is personal safety, and it is usually offered as a partial-day course added onto S-100 training. Trainees learn about the hazards that can lead to entrapment situations (i.e. limited escape routes, fuel hazards) and how to evaluate these hazards before it is too late. They also learn when and how to remove themselves from risky situations and other strategies to help prevent a loss of life.
