The short answer
Professional event security should coordinate with the venue and event leadership, and it should have clear procedures for contacting police, fire, or emergency medical services. However, Arrow’s current public service pages do not describe the exact coordination process for every event, so that capability and scope should be confirmed in the proposal.
What to know
Effective coordination begins with a named event decision-maker and security supervisor. The plan should identify radio or phone channels, emergency contacts, command location, responder access route, ambulance and fire lanes, evacuation authority, lost-person procedures, evidence preservation, and who communicates with guests or media. Venue security, ushers, bartenders, medical staff, parking teams, and private guards need distinct duties to avoid duplication or dangerous gaps.
For higher-risk or larger events, organizers should contact local agencies early enough to determine permit, staffing, traffic, fire-code, or emergency-planning requirements. Private security officers support the plan but do not direct public responders or assume police authority. A pre-event briefing and post-event review make the arrangement accountable. Ask Arrow to state which meetings, site walks, plans, and agency contacts are included in its quoted service.
