California Code, Education Code - EDC § 38005

The governing board of any school district may contract with a private licensed security agency to insure the safety of school district personnel and pupils and the security of the real and personal property of the school district when the personnel normally required to provide such service fail to do so because of an emergency including, but not limited to, war, epidemic, fire, flood, or work stoppage; or when such an emergency necessitates additional security services.

This section shall apply only if the governing board by a majority vote makes a specific finding that an emergency exists, and that this finding is included in the board minutes.
