One Gate, 1,800 People, and Rain
At 6:15 pm you are the lead controller at an outdoor festival with a licensed capacity of 1,800. Gates opened at 6 pm through a single 3.5-metre-wide entry corridor with one bag-check table. About 420 people are queued along a fenced path; a train has just arrived and the back of the queue is pressing forward. The ground is wet, the temperature is 14°C, and the event starts at 7 pm. At the front, people cannot move because bag checks have slowed; a woman stumbles and a child aged about eight is separated from an adult. You have two controllers at the gate, one at bag check, and no PA in the queue. The nearest first-aid post is 200 metres inside the site.
1. Identify the crowd-risk factors and early warning signs in this queue, and explain how they interact.

Risk factors: a single 3.5 m entry point with one bag-check table creates a bottleneck; 420 people arriving in a surge after a train; wet ground and cold, dark conditions; event-start pressure at 7 pm; no PA so people at the back cannot see or hear why they are stopped; only three controllers for the queue; vulnerable people (a child, a woman who stumbled); and a fenced path that limits escape. Early warning signs: the queue stops moving, people at the back push because they cannot see the front, bodies are in contact, someone stumbles, a child is separated, and lateral pressure builds. These interact: the bottleneck creates the stop, the train creates the surge, the lack of information makes people push, and the fence removes escape routes. That is how a queue becomes a crush. The aim is to reduce density, not to push people back.
2. What immediate actions would you take in the next five minutes, and why?

- Stop the rear pushing: send one controller to the back with a clear message and visible presence, and ask people to hold a gap. 2) Increase throughput: add a second bag-check position if safe, or move bag check to a wider point; do not pause checks without a plan. 3) Create space: if a second gate can be opened safely, open it and meter both lanes; if not, hold the queue in smaller batches behind a buffer. 4) Communicate: use a radio to get a PA or loud hailer to the queue; give a short script: 'We are managing entry safely. Please keep space and follow staff.' 5) Care: take the separated child to the first-aid post, make an announcement, and check the woman who stumbled. 6) Record times and decisions. Do not let staff push people back with hands or barriers; that increases pressure. Ask event control to delay the start if needed.
3. What should be recorded and passed to the event safety lead?
Read the worked answer
Record the time the queue surge began, approximate numbers, the train arrival, the gate and bag-check layout, staff numbers, the child separation and reunion, the woman's stumble and any injury, the PA request, any gate opened, and the decisions made by whom. Note the weather and ground conditions. Pass an incident report to the event safety lead the same night, with a sketch of the queue layout and the limited exits. Recommend a review of arrival profiling, a second entry lane, a queue PA, and a metering plan. Keep it factual: times, observations, actions, outcomes. Do not write opinions about individual patrons. If an injury occurred, complete the venue's accident form and preserve CCTV.
