to the facility by the end of the period of emergency detention, the

shall be discharged from the facility in which detained unless said

person has applied for voluntary treatment.

detention shall be asked to designate any person whom such person

wishes informed regarding the detention. If the person being held

custody, other than the person initiating the request for protective

custody, the attorney, parent, spouse, guardian, brother, sister, or
