From the district's Board of Park Commissioners and Administrative Policy & Procedures Manual, Section 2.12: 

Proper medical treatment following a sustained head injury by a Park District patron is extremely important. An individual is often disoriented and not necessarily able to make sound decisions regarding their medical treatment after a head injury.  As such, and as encouraged by Section 8-24 of the Park District Code, the District will use reasonable efforts to make available to users of District facilities electronically or in written form, concussion and head injury educational materials which may include those produced or distributed by the Illinois High School Association, the U.S. Centers for Disease Control and Prevention or other comparable materials.
