Like many of us working in event safety, I followed the coverage of the Astroworld tragedy closely when it happened in 2021. I studied the initial reports, read through expert analysis as it became available, and paid attention to the growing litigation. But during our weeklong course at AVSS, something shifted. Hearing the incident unpacked in person by seasoned crowd management and event safety professionals was different. Watching real-time videos with a room full of colleagues and engaging in discussion about what went wrong and what could have been done, gave the tragedy a new weight. It wasn’t just a case study anymore, but felt more like a call to action.
That lecture didn’t just add information to what I already knew – it gave it magnitude. It made me confront the reality of managing thousands of people in a confined space and the heavy responsibility that comes with it. It also made me think more critically about the stories behind other major incidents. How many have I skimmed over or archived in my brain as “just another tragedy” without letting the lessons fully sink in?
We often think we understand these stories because we’ve heard about them before, but sometimes it takes a deeper look or the right moment for the gravity of the incident to truly land. That’s why it’s worth revisiting the cases that have shaped our field. Below are five that every safety professional working with crowds should know inside and out. I challenge you to not just read the names and nod, but to really sit with them.
1. Hillsborough Disaster (1989) – Sheffield, England
Ninety-seven soccer fans lost their lives when overcrowding in the standing terraces led to a catastrophic crush. Police failed to manage the flow of fans entering the stadium, and poor crowd monitoring only made it worse.
Key Takeaways:
2. Love Parade Disaster (2010) – Duisburg, Germany
A techno music festival held in a space too small for the expected crowd led to a bottleneck in a tunnel. Panic and pressure built up until 21 people were crushed to death and over 500 were injured.
Key Takeaways:
3. Station Nightclub Fire (2003) – West Warwick, Rhode Island
Pyrotechnics ignited flammable soundproofing during a rock concert, resulting in a fire that killed 100 people. Many victims were trapped trying to exit through the same front door they entered.
Key Takeaways:
4. Mecca Hajj Stampede (2015) – Mina, Saudi Arabia
During the pilgrimage, over 2,000 people died in one of the deadliest crowd crushes in history. Complex rituals and massive crowds, combined with intense heat and unclear instructions, contributed to the scale of the tragedy.
Key Takeaways:
5. Astroworld Festival (2021) – Houston, Texas
A surge toward the stage led to a crowd crush that killed 10 people and injured hundreds. Despite visible distress signals, the concert continued for nearly 40 minutes.
Key Takeaways:
The show must not go on when lives are at risk.
Crowd management is part science, part art, and all responsibility. What happened at Astroworld, and all of the other events highlighted here, are reminders of what’s at stake when large numbers of people gather. But they’re also reminders of what’s possible when we do things right.
Whether you’re planning your next event, running safety operations at a venue, or just beginning your journey in this field, commit to continuous learning. Don’t wait for a tragedy to force reflection. Learn from history, study the patterns, and plan like lives depend on it – because they do.
