Every event begins with the same goal: to create an experience that people will remember for all the right reasons. Planners attend to myriad details to create positive experiences. But it's equally important to consider the things that could go wrong.
Case studies about event emergencies help us learn from real-world experience. They help us examine the decisions and conditions that shaped an event, identify factors that contributed to the emergency, and ask the question that matters most: What could prevent this from happening in the future?
For event safety professionals, these lessons are invaluable. In this post, the first in an occasional series, we'll explore event disaster case studies and the practical safety lessons they can teach us, with a focus on turning past failures into better planning and safer events.
2026 Shooting at Bite of Seattle
Seattle Center is a 74-acre arts and entertainment campus in downtown Seattle. On July 26, 2026, the site was hosting a food festival called The Bite of Seattle when shooting erupted. Three people were killed and four others were wounded, including a toddler.
Key learnings:
- The Bite of Seattle festival was open-air, and allowed participants to roam freely. Consider ways to cordon off festival space to limit access to those who have gone through security screening. Adding metal detectors can act as a deterrent for those with weapons as well as a screening feature.
- Police responded immediately to reports of shots fired. Advanced coordination with local police and EMS can improve response time, leading to more timely apprehension of suspects and administration of first aid.
- Seattle PD was criticized for its delay in communicating about the shooting. Communicating with attendees and the public can reduce anxiety. Developing holding statements in advance allows you to quickly communicate, even in periods of uncertainty and high stress.
2015 Circus Tent Collapse in New Hampshire
In Lancaster, New Hampshire, an extreme storm caused a circus tent to collapse during a performance by Walker International Events. Two people were killed and dozens were injured when 60 mph winds, hail, and lightning bombarded the tent.
Key learnings:
- The National Weather Service issued a severe storm warning 23 minutes before the collapse. All events should designate a person to check the weather leading up to and during events. Making it a specific person's responsibility creates a safety routine. Venue managers or event organizers should set specific thresholds (i.e., wind over X mph, any lightning, etc.) that will trigger cancellation.
- There were no permanent structures to shelter circus attendees. Tents do not provide adequate protection during lightning events or high winds. Consider the distance to each shelter, the capacity of the enclosure, and time needed to evacuate participants.
- Attendees helped to evacuate the injured, effectively becoming emergency personnel themselves because emergency roles for staff members were not clearly defined. Assigning and communicating specific emergency roles to staff in advance can prevent response from defaulting to untrained bystanders during a crisis.
2010 Love Parade
The Love Parade electronic music festival was notorious for attracting large crowds. In 2010, the festival was held in the German town of Duisburg in an area that had limited access points. As festival-goers tried to enter the site through a narrow tunnel, the crowd surged, causing 21 deaths from suffocation and injuring 658 participants.
- The event site had a maximum capacity of 250,000, but it's estimated that more than 1 million people showed up to the free festival. Ensure that the site matches the expected attendance or limit attendance to keep guests safe.
- The layout of the Love Parade site had numerous bottlenecks that inhibited crowd flow. Design event spaces with the complete system in mind. Minimize obstacles that could lead to crowd-crush events, and include evacuation routes as part of the planning.
- During testimony about the disaster, the chief advisor to the police deployment cited many small failures among his team, but noted that the overarching failure had been an inability to understand the extent of the problem. Training staff to recognize the signs of erratic crowd behavior can help them prevent a crisis or detect one early enough to mitigate harm. Staff members should also be empowered to escalate and to ask for assistance. Communicating broadly among the team can help team members put the pieces of the picture together.
While not every crisis can be predicted, these disasters demonstrate the importance of building systems that are flexible enough to respond to the unexpected. By studying what went wrong at past events, planners can turn hard lessons into proactive measures that protect attendees, staff, and communities. The best event is one where safety planning works so well that no one ever notices it, but everyone benefits from it.
