Outdoor Event Severe Weather Response A regional wind-warning threshold does not tell you whether a stage or tent can stay in use. Agree operating limits with those responsible for the installation and name who monitors, reports, stops and restarts the event.

Responsible roles / intended readers: Overall operations, safety and structural teams Record / next task: Structure-specific weather response, stop, evacuation and restart checklist Basis of information: Practical decision guide Editorial review: 2026-10-20 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. Practical workflow · Role handover Communicate a stop under site conditions Roles: Weather monitoring / reporting · Stop decision-maker · Stage / visitor information 1. [Weather monitoring / reporting] Monitor and measure Use approved criteria, locations and responsibilities 2. [Weather monitoring / reporting] Report findings Compare forecasts and readings with installation limits 3. [Stop decision-maker] Decide the stop The preassigned decision-maker issues the instruction 4. [Stage / visitor information] Act on site Stop performance or admission and inform visitors Note: Confirm actual actions and thresholds with competent personnel who reviewed the installation. 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. Practical workflow · Parallel work Check before restarting after evacuation Start: Check shelter and weather Compare capacity, routes, support and weather with the site plan Parallel items: - Inspect systems and routes Relevant owners check structures, electrics and passages - Confirm staffing and return readiness Check staffing, radio and operational readiness for return after approval Check the parallel items together before continuing After the join: Decide and announce restart Combine findings and apply the site approval procedure Note: Improved weather alone does not authorise restart. Size alone does not make a lightning shelter safe. US NWS guidance recommends a substantial building with electrical wiring and plumbing; open rain shelters are not safe. Confirm designated refuges against local requirements with qualified personnel. Operational workflow Practical workflow · Decision From weather risk reports to restart approval and return 1. Agree structure-specific limits and contacts in advance Qualified personnel define operating limits, measurements, observers, reporters and stop authority; rehearse the response. 2. Monitor conditions and report risks The observer compares readings, including average and gust wind speeds, with the agreed site-specific criteria and reports to the event lead. 3. Authorized lead orders the stop Apply the consolidated response table and communicate the show stop to every team by radio and emergency announcement. 4. Direct evacuation and control access Guide performers and spectators to a sturdy indoor shelter assessed in advance. Do not use tents as shelters. 5. Technical team reinspects after weather improves Check structural deformation, detached fixings and water ingress into electrical equipment; report the safety inspection results to the event lead. Decision question: Are the safety check and final restart approval both confirmed? [Incomplete or unapproved] Keep the show stopped and access controlled No early return by spectators or staff. Address remaining hazards, then confirm technical checks and final approval before reassessment. [Check and approval confirmed] 6. Confirm all staff back in position Only after approval, field operations confirms each team's return, radio response and readiness to direct people. 7. Guide spectators back and resume operations Begin spectator return guidance and restart the event only after confirming that all responsible staff are in position. Note: Do not use weather-warning thresholds as structural operating limits. This diagram provides neither numerical limits nor a safety assessment. Improving weather alone does not authorize restart. **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. Application conditions Agree thresholds and actions with competent contractors or specialists familiar with design, ground, anchoring, ballast and exposed area, plus venue and local requirements. Size alone does not make a lightning shelter safe. US NWS guidance recommends a substantial building with electrical wiring and plumbing; open rain shelters and small outdoor buildings are not safe. Confirm designated refuges against local requirements with qualified personnel. Unconfirmed information Overseas HSE and NWS references do not replace Korean statutory standards. Installation safety and site operating limits need separate confirmation. Sources Korea Meteorological Administration — Strong-wind safety actions and warning thresholds.
