Outdoor Event Severe Weather Response

Part 1. Planning and Procurement Lead

"Combine fragmented manuals and document the decision-maker and timeline."

• Do not misinterpret weather warnings: The absence of a Korea Meteorological Administration strong-wind advisory does not mean an event can safely continue. The wind limits for truss, LED supports, outdoor tents and other structures at the venue may be much lower.
• Prepare a combined response plan for each structure: Gather the safety criteria held by suppliers for stages, speaker towers, tents and other systems into one integrated weather response and evacuation checklist.
• Establish the decision-making chain: To prevent confusion, specify who monitors conditions, who receives the report, and the designated decision-maker who ultimately declares a show stop when a specified weather condition is reached.

Part 2. Facilities and Technical Director

"Do not guess at the design limits of structures. Check the qualified contractor's calculations."

• Set operating limits for each structure: Stage safety depends not only on the frame but also on ground conditions, ballast and the area exposed to wind; conditions can change in real time. Set precise wind limits that reflect each structure's characteristics.
• Measure and report weather in real time: Do not rely solely on a forecast app. Install wind meters at major structures within the venue, monitor changing readings in real time, and report immediately to the control room when readings approach the established limits.
• Inspect infrastructure before reopening: Do not restart merely because the weather has improved. After strong wind or heavy rain, the technical team must first inspect for structural deformation, displaced anchoring pins, flooded electrical cables and other electric shock hazards, and determine whether it is safe to resume.

Part 3. Floor Operations and Stage Manager

"A rain tent is not a shelter. Secure a safe refuge and evacuation routes."

• Simulate evacuation for lightning and sudden weather: Small outdoor rain tents are not safe shelters during lightning. Mark evacuation routes on the venue plan that can guide visitors and staff to a preassigned refuge in a substantial indoor building or large structure.
• Rehearse a shutdown: During cue-sheet rehearsals, simulate an event stop caused by worsening weather and practice the announcements, performer evacuation, audience control and staff radio reporting as they would occur on site.
• Control staff return and event restart: When the weather improves, prevent visitors from entering the stage and staff from returning early until safety checks are complete. Once the operations lead gives final approval to restart, confirm that all staff are back in position before beginning visitor announcements.

Final check before use: Small variables at outdoor events can lead to major accidents. Before the venue opens, check that all operations staff have completed a severe-weather simulation exercise.
