Imminent means: likely to occur at any moment, or near at hand. Not distant or remote.
Likelihood of serious harm means: a substantial risk that a person will cause physical harm to themselves or another person, or substantial loss or damage to another person’s property. Evidence that there is a likelihood of serious harm might include:
- threats or attempts to commit suicide or harm themselves;
- behavior that has physically harmed someone in the past, or makes a person reasonably fear they will be physically harmed;
- behavior that has caused substantial damage in the past; or
- a threat to someone else’s physical safety, if the person making the threat has a history of one or more violent acts.
