Ala. Code § 12-16-191
It shall be the duty of the grand jury to determine at least once annually the condition of the county jail in regard to its sufficiency for the safekeeping of prisoners and their accommodation and health and to inquire into the manner in which the same has been kept since the last determination. The determination may include a personal inspection and a review of all inspection records of the jail. If it shall be found that such jail is not constructed in the manner prescribed by law and so strongly and securely built as to prevent the escape of prisoners confined therein and properly ventilated, the grand jury shall, as often as may be necessary, present its findings to the district attorney, sheriff and county commission for appropriate action.
