Direct warnings are references to suicide or to being dead.  These usually come at the end of the Crisis stage, just before a suicide. Common warnings include:

• comments or jokes about suicide
• talking about committing suicide
• making plans to commit suicide like carrying a rope, collecting Tylenol, etc.
• poems, stories, plays, essays, or drawings about suicide or being dead
• mention of a suicidal fantasy

Warning behaviours

• A previous suicide attempt, especially if it is recent, indicates that the person is at high risk for suicide (an attempt is any time that a person's suicidal intent and a method come together)
• self-mutilation (ie. slashing, cutting, burning) may be an warning sign
• the more frequent thinking of suicide the greater the risk; for example, a person who thinks about suicide for hours, every day for a wekk is more at risk.
