Figure 1

This image is a graph showing the conceptual risk model for determining containment level.

• The vertical axis of the graph shows the risk of escape and establishment.
• The horizontal axis of the graph shows the risk of impact.
• When both the risk of escape and establishment and the risk of impact are very low, no containment is required.
• When the risk of escape and establishment is very low and the risk of impact is low, the containment level is basic.
• When the risk of escape and establishment is very low and the risk of impact is medium, the containment level is PPC-1.
• When the risk of escape and establishment is very low and the risk of impact is high, the containment level is PPC-1.
• When the risk of escape and establishment is low and the risk of impact is very low, the containment level is basic.
• When both the risk of escapement and establishment and the risk of impact are low, the containment level is basic.
• When the risk of escape and establishment is low and the risk of impact is medium, the containment level is PPC-1.
• When the risk of escape and establishment is low and the risk of impact is high, the containment level is PPC-2.
• When the risk of escape and establishment is medium and the risk of impact is very low, the containment level is PPC-1.
• When the risk of escape and establishment is medium and the risk of impact is low, the containment level is PPC-1.
• When both the risk of escape and establishment and the risk of impact are medium, the containment level is PPC-2.
• When the risk of escape and establishment is medium and the risk of impact is high, the containment level is PPC-3.
• When the risk of escape and establishment is high and the risk of impact is very low, the containment level is PPC-1.
• When the risk of escape and establishment is high and the risk of impact is low, the containment level is PPC-2.
• When the risk of escape and establishment is high and the risk of impact is medium, the containment level is PPC-3.
• When both the risk of escape and establishment and the risk of impact is high, the containment level is PPC
