**Technique and Execution**: The way the hang is performed (e.g., the type of knot, position of the noose, method of suspension) can significantly impact the effectiveness of the method.

**Mental State**: Individuals seeking to end their lives may be under significant emotional distress or may not be in a clear state of mind to properly execute the method.

**Circumstances**: Environmental factors such as the surface beneath the person, available support structures, and other situational elements can affect both the success and method of hanging.

**Misunderstanding of Mechanism**: Some accounts may not fully understand how suffocation works in hanging, which can lead to failures in achieving the intended outcome.

**Access to Immediate Help**: In some cases, individuals may be rescued before the method can take full effect, especially if they are not fully suspended or if there is quick intervention.
