− Expanding phase, where the incident is likely to expand beyond accepted limits. The incident is uncontrolled and requires rapid actions to control risks to lives and property. Some level of risk may be acceptable.

− Contained phase, where there are sufficient resources to contain the incident within a defined area. There is no life at risk, or lives and property are already lost. Risk must be minimised as much as practicable.
