It can be implemented following a (usually brief) assessment by the RC or his deputy, which, in effect, means any hospital doctor, including psychiatrists but also those based on medical or surgical wards. It lasts up to 72 hours, during which time a further assessment may result in either discharge from the section or detention under section 2 for assessment or section 3 for treatment. Section 5(4) is a nurse's holding power. It can be applied to the same group of patients as those that may be detained under section 5(2) as outlined above. It is implemented by a first or second level Mental Health or Learning Disability Nurse.

This only applies to a person found in a public place. Once a person subject to a Section 135 magistrates' order or Section 136 police officers' order is at a place of safety, they are
