Explanation:

Acting on the request of the Ministry of Home Affairs, NIMHANS, an Institute of National Importance, issued a set of guidelines on the management of mental health issues of the prisoners and prison staff. 

• In the Gatekeeper Model for Identification of Mental Illness, selected inmates, trained to identify prisoners at risk of suicide, would refer them to treatment or supportive services.
• Prisoners with mental disorders had to be regularly assessed for severity of suicidal risk and also put on regular and supervised medication.

Buddy System for Social Intervention

• It is a type of social support through trained prisoners called “buddies” or “listeners".
• It was found to have a good impact on the well-being of suicidal prisoners. Periodic telephone conversations with friends and family would also foster support.

Hence only statement 1st is correct.
