A prisoner can be segregated from other prisoners if it is necessary:

• in order to prevent the prisoner from seriously endangering the life or health of another person;
• to prevent an evident attempt at escape or release;
• to prevent the continuous use of an intoxicating substance or to prevent a narcotics offence; or
• to prevent another act seriously endangering prison order.Segregation is not a disciplinary punishment but a precautionary measure. It cannot be continued longer than necessary.

A prisoner can also be segregated from other prisoners on his or her own request if there is a justifiable reason for it.

The rights of a segregated prisoner cannot be restricted more than is necessary.

In 2009, an average of 166 prisoners were segregated on their own request daily. The year before, the amount was higher, i.e. 201.
