According to the Centre for Suicide Prevention, a safety plan is a document that supports and guides someone when they are experiencing thoughts of suicide, to help them avoid a state of intense suicidal crisis. Anyone in a trusting relationship with the person considering suicide can help draft the plan; they do not need to be a professional.

A safety plan is written when a person is not experiencing intense suicidal thoughts. It may be written after a suicidal crisis, but not during, as at this time an individual can become overwhelmed with suicidal thoughts and confusion and may not be able to think clearly. A safety plan is written when a person has hope for life, or even can consider the possibility of life, so that they can identify their reasons for living, and positive actions they can take to prevent their thoughts from becoming intense and overwhelming.

A safety plan can be developed in one sitting by the person with thoughts of suicide together with you, their caregiver or friend, or over time. The plan can change as the circumstances for the individual change and can be revised accordingly.
