Cal. Health & Safety Code § 1257.7

(a) After July 1, 2010, all hospitals licensed pursuant to subdivisions (a), (b), and (f) of Section 1250 shall conduct, not less than annually, a security and safety assessment and, using the assessment, develop, and annually update based on the assessment, a security plan with measures to protect personnel, patients, and visitors from aggressive or violent behavior. The security and safety assessment shall examine trends of aggressive or violent behavior at the facility. These hospitals shall track incidents of aggressive or violent behavior as part of the quality assessment and improvement program and for the purposes of developing a security plan to deter and manage further aggressive or violent acts of a similar nature. The plan may include, but shall not be limited to, security considerations relating to all of the following:
1. (1) Physical layout.
2. (2) Staffing.
3. (3) Security personnel availability.
4. (4) Policy and training related to appropriate responses to violent acts.
5. (5) Efforts to cooperate with local law enforcement regarding violent acts in the facility.
  In developing this plan, the hospital shall consider guidelines or standards on violence in health care facilities issued by the department, the Division of Occupational Safety and Health, and the federal Occupational Safety and Health Administration. As part of the security plan, a hospital shall adopt security policies including, but not limited to, personnel training policies designed to protect personnel, patients, and visitors from aggressive or violent behavior. In developing the plan and the assessment, the hospital shall consult with affected employees, including the recognized collective bargaining agent or agents, if any, and members of the hospital medical staff organized pursuant to Section 2282 of the Business and Professions Code. This consultation may occur through hospital committees.
(b) The individual or members of a hospital committee responsible for developing the security plan shall be familiar with all of the following:
1. (1) The role of security in hospital operations.
2. (2) Hospital organization.
3. (3) Protective measures, including alarms and access control.
4. (4) The handling of disturbed patients, visitors, and employees.
5. (5) Identification of aggressive and violent predicting factors.
6. (6) Hospital safety and emergency preparedness.
7. (7) The rudiments of documenting and reporting crimes, including, by way of example, not disturbing a crime scene.
(c) The hospital shall have sufficient personnel to provide security pursuant to the security plan developed pursuant to subdivision (a). Persons regularly assigned to provide security in a hospital setting shall be trained regarding the role of security in hospital operations, including the identification of aggressive and violent predicting factors and management of violent disturbances.
(d) Any act of assault, as defined in Section 240 of the Penal Code, or battery, as defined in Section 242 of the Penal Code, that results in injury or involves the use of a firearm or other dangerous weapon, against any on-duty hospital personnel shall be reported to the local law enforcement agency within 72 hours of the incident. Any other act of assault, as defined in Section 240 of the Penal Code, or battery, as defined in Section 242 of the Penal Code, against any on-duty hospital personnel may be reported to the local law enforcement agency within 72 hours of the incident. No health facility or employee of a health facility who reports a known or suspected instance of assault or battery pursuant to this section shall be civilly or criminally liable for any report required by this section. No health facility or employee of a health facility who reports a known or suspected instance of assault or battery that is authorized, but not required, by this section, shall be civilly or criminally liable for the report authorized by this section unless it can be proven that a false report was made and the health facility or its employee knew that the report was false or was made with reckless disregard of the truth or falsity of the report, and any health facility or employee of a health facility who makes a report known to be false or with reckless disregard of the truth or falsity of the report shall be liable for any damages caused. Any individual knowingly interfering with or obstructing the lawful reporting process shall be guilty of a misdemeanor. “Dangerous weapon,” as used in this section, means any weapon the possession or concealed carrying of which is prohibited by any provision listed in Section 16590 of the Penal Code.
