"This evacuation guide is intended to assist the stadium's owner/operator with developing and implementing an Evacuation Plan by serving as a guide for stadium emergency managers charged with planning for the protection of stadium spectators and participants in the event of an incident. Many stadiums currently have Evacuation Plans containing procedures for evacuation, as well as relocation and sheltering in place during specific incidents. This guide will assist stadium owners/operators with preparing an Evacuation Plan, and determining when and how to evacuate, shelter in place or relocate stadium spectators and participants. The Evacuation Plan should be included as an appendix to the Stadium's Emergency Plan. The Evacuation Plan is only intended to supplement the Emergency Plan with regard to evacuation procedures. The Evacuation Plan should reference, but not include, any activities or processes that are inherently found within the stadium's Emergency Plan."
