Which tier is the venue in
Standard tier (200–800) requires published procedures, staff training, and public awareness. Enhanced tier (800+) adds risk assessment, protective measures and a documented plan.
The three responses
Evacuate (get out), invacuate (get in and shelter), lockdown (deny access). Staff must know which applies in each scenario and rehearse it.
Where guards fit
Frontline sensors, first responders on evacuation, communications relay, marshalling of the public. Guard-level training is non-optional in enhanced-tier venues.
