Yes. The code basically states, That any law enforcement officer, based on their own observations or the reliable reports of others, feels as though the person needs to be evaluated for emergency hospitalization, they may be taken into custody and held for not more than four hours. This is known as an Emergency Custody Order, even though a paper order hasn't been issued.
Within the four hours, the person must be evaluated and if the person is going to be TDO'd to a hospital, it must be done within the four hours.
