People Don’t Die Because They Panic: The Truth About Crowd Disasters with Dr G. Keith Still.

People Don’t Die Because They Panic: The Truth About Crowd Disasters with Dr G. Keith Still.

Send us an email [https://www.buzzsprout.com/2501851/fan_mail/new] When a crowd disaster makes the news, two words usually appear almost immediately: panic and stampede. Dr G. Keith Still argues that both terms are often wrong. They place the blame on the crowd, when the real failures may have happened months earlier through poor planning, misunderstood capacity limits, weak crowd-flow analysis and safety documents that were never properly tested. In this episode, David Franklin speaks with one of the world’s leading crowd science specialists about how crowds really move, what happens when density reaches dangerous levels, and why people do not simply behave irrationally in an emergency. Keith explains the relationship between crowd psychology and physical crowd dynamics, including the point at which a crowd begins to behave more like a physical system than a collection of individuals. They also discuss: * Why people often leave through the entrance they already know * The difference between crowd panic, crowd crush and progressive crowd collapse * What changes between five and six people per square metre * Why smooth computer simulations can create false confidence * How simulations should test failure, not simply demonstrate success * The DIM-ICE and RAMP crowd-safety models * Why simple site plans, tracing paper and coloured pencils can outperform expensive software * The difference between an experienced crowd manager and a competent one * Common warning signs in generic and copied risk assessments * How crowd risk should be addressed across ingress, circulation and egress * Why site-specific diagrams and flowcharts strengthen event safety documentation * The importance of live, current and venue-specific operational plans * What Martyn’s Law could mean for event documentation, training and crowd communication Keith also shares examples from his work on major international events and crowd-safety investigations, including the Hajj, the Olympic Games, the Love Parade disaster, Astroworld and Hillsborough. This is an essential conversation for event organisers, venue operators, safety professionals, security managers, licensing officers and anyone responsible for planning or managing places where crowds gather.

It Was Never a Stampede: The Deadly Physics of Human Crowds

Send us an email [https://www.buzzsprout.com/2501851/fan_mail/new] The difference between a safe exit and a tragedy is arithmetic. This episode walks through Introduction to Crowd Science by Prof G. Keith Still: why 'stampede' and 'panic' are words that blame the victims, why crowd disasters are system failures built in months before the gates open, and why the tools that actually save lives are a map, a clicker and a piece of string. We cover the body ellipse and the five people per square metre ceiling, shockwaves and compressive asphyxia, Hillsborough and the Love Parade, RAMP analysis and the DIM-ICE model, the CCTV illusion that fools control rooms, and the 80 per cent rule behind London's New Year fireworks. Plus the one variable no simulation on earth has a line of code for: a police horse. Correction: in the episode we describe simulation software allowing digital crowds to pack at 6.25 people per square metre, beyond the danger threshold. Prof Still's point is the reverse. Grid-based simulations cap packing at 6.25 people per square metre, while real crowds reach crushing pressure at 7 to 10. The software cannot reach the densities that kill, so it can never show you the risk. The conclusion stands, and is stronger for the fix: treat simulation outputs with expert care.

The Ratio Myth: How Many Medics Does Your Event Actually Need?

Send us an email [https://www.buzzsprout.com/2501851/fan_mail/new] Most event medical plans still start with a table. Attendance on one axis, first aiders and ambulances on the other. Trace your finger across the grid, write the number down, file the plan. That table is not evidence. It is a group of professionals sitting in a room decades ago making educated guesses, and those guesses ignored almost everything that actually drives injury and illness at an event. In this episode we take the attendance ratio apart and look at what replaces it. What we cover: * Why a low-participation, fully seated event can run a presentation rate as low as 0.01 per 1,000, and why moshing and crowd surfing drive a 10 to 20 fold increase on the same headcount * Temperature, which has one of the highest impacts of any variable factor: expect as much as a 10% rise in presentation rate for every 1°C above 20°C, and a doubling of the rate if free drinking water is not available * Bounded versus unbounded events, crowd density, and the critical density point at around 5 people per square metre, beyond which people cannot reach care and cannot help themselves * The 200 metre rule: a team walking freely covers around 432 metres in four minutes, but in a crowd that collapses to about 216 * Case mix, the five tiers of severity, and why a marathon needs volume while a racecourse needs a trauma-capable team * The transport to hospital rate, the industry's real measure of success, and why under-staffing on the front end drains the local NHS on the back end * Duty of care, the Caparo test and the Bolam test: why "we used the same table everyone else uses" is not a defence * The event to host population ratio, and how a 4,000 person event in a village of 500 can swallow every ambulance in the county The closing question is the one worth sitting with. If every degree above 20°C means as much as 10% more patients, and baseline temperatures keep rising, at what point does the traditional outdoor summer festival become mathematically too expensive to cover in its current form? A note on two figures in this episode. The 8 to 12 presentations per 1,000 figure, and the 15% concussion and 20% fracture rates, apply to horse jump racing and to jockeys, not to equestrian cross country. The manual puts equestrian eventing nearer a PPR of 15 and competitive cross country at 15 to 22. The manual also notes that the true workload in horse racing is closer to a PPR of 50 to 70, because there are 50 to 70 falls per 1,000 race starters and every faller needs assessment; the 8 to 12 figure counts only those actually injured. Separately, the transport to hospital gold standard is under 1%, achieved by the best providers. Under 2% is the target most events should aim for. Full detail is in the accompanying article.

Our discussion covers a wide array of fascinating logistical challenges, from the engineering behind rigging and electrical installations to the strict protocols surrounding medical treatments, adult entertainment, and the use of live animals or drones on the exhibition floor. Whether you are coordinating crowd management, building temporary demountable structures, or ensuring robust safeguarding and accessibility measures for all visitors, this episode breaks down the crucial rules every event professional needs to know to keep the show running safely

Navigating the 'Severe' National Threat Level

Send us an email [https://www.buzzsprout.com/2501851/fan_mail/new] On April 30, 2026, the Joint Terrorism Analysis Centre (JTAC) raised the UK National Threat Level from Substantial to SEVERE, indicating that a terrorist attack is highly likely. In this critical episode, we break down what this shift means for businesses, organizations, and the general public. We examine the recent statement from the Head of Counter Terrorism Policing, Laurence Taylor, who highlighted the growing risks driven by both Islamist and Extreme Right-Wing terrorism, alongside an elevated threat to Jewish and Israeli communities. We also guide you through actionable protective security measures, detailing the ProtectUK Risk Management Process—a five-stage approach to identifying, assessing, and treating security vulnerabilities. Listeners will learn about deploying enhanced, temporary security controls using the Menu of Tactical Options (MoTO) during periods of heightened risk and gain crucial insights into recognising five key terrorist attack methodologies, including Marauding Terrorist Attacks (MTA) and Vehicle As a Weapon (VAW). Join us as we discuss how to remain vigilant, implement robust security plans, and stay alert, but not alarmed.
