This guide sets forth minimum standard requirements for use in local codes and ordinances relating to ballfield containments.

This guide does not have the effect of law, nor is it intended to supersede local codes and ordinances of a more restrictive nature.

Studies, as listed in Annex A1, have been referenced as the basis for certain recommendations in this guide and will assist those who intend to provide protection against injuries or fatalities associated with anticipated thrown or hit balls and bats as well as passage to or from a ballfield or other sports environment, thus restricting and deterring passage. This would include, but not be limited to, state and local governments, model code organizations, building code groups, and consumers. It is understood that the format will vary depending upon the specific use and local conditions.

Articles and studies have noted that fencing for baseball or softball sports, or both, should exist for baseball and softball sports outfields, player seating, and sidelines.
