Safeguard prisoner wellbeing
Tephra’s Behaviour and Life Signs Monitoring can help address custodial challenges by providing continuous insight into prisoner behaviour and alerts to sudden changes requiring intervention. This positively impacts prisoner health and wellbeing and can alleviate stressful environments. Latest figures show:
Every 4 days
On average, a prisoner in the UK dies by suicide
1 in 5
suicides occur within the person’s first 30 days in custody
1 in 7
suicide cases occur within the first week.
One in every 7
minutes a self harm incident occurs in prison

Background
Custodial settings are high risk environments where staff must balance safety, security and rehabilitation, while facing the growing challenge of rising self harm, suicide attempts and the urgent need to support vulnerable prisoners before incidents escalate.
Despite best efforts, traditional monitoring methods such as scheduled checks and CCTV, leave critical gaps where key moments of distress often go unnoticed. Vital sign alerts, while valuable, provide only a small window to react, when an incident is already unfolding, limiting the opportunity for preventative action.
With increasing pressures on staff and resources, the need for proactive real-time solution that identifies risk before it escalates has never been greater.
