Chemical, Biological, Radiological & Nuclear (CBRN) terrorism: warning and informing the public around a new type of threat

Over the past year we’ve worked with teams across the globe to rehearse a range of interesting and important crisis scenarios. From product recalls to corporate malpractice, and campaign failures to extreme weather responses, we’ve put hundreds of teams through their paces to assess how they manage a crisis. Notably, the most common simulation scenario of 2018 involved a form of cyber threat. However this year, and looking into 2019, we’re working more and more with agencies practicing their response to security incidents, such as terrorism – but not the cases involving guns and loud explosions.

During the past twelve months we’ve helped various agencies rehearse how they would coordinate and communicate a public response to a Chemical, Biological, Radiological and Nuclear (CBRN) attack – as seen tragically for the first time in the UK in Salisbury, England in March this year.  Increasingly we’re working with clients to practice managing their response to these types of attacks – events that are complex, often invisible, and far reaching in impact. Equally as serious as devices that explode with force, CBRN devices pose a great risk to public safety.

The challenge of a new type of terror threat

The commonly known public messaging concerning counter-terrorism in the UK revolves around the concept of the public seeing it, saying it, to allow it to be sorted. The challenge for agencies responding to CBRN attacks is altering this messaging to communicate how the public should react to a terror event that may be unseen – such as a chemical, or a strain of virus being released into the air. How many people need to fall ill before someone registers it and believes reporting the event is necessary? By that point in time has the substance or virus spread? Can it be contained? What is it? How can do we contain something we don’t know?

It’s a challenge for communicators to co-ordinate not just bluelight responders but also the scientific, government and public health advice. It has to happen while the facts are still being established, and at a speed that’s alarming to those more used to providing advice to ministers or as part of planned campaigns.

Working with the unknown is challenging at the best of times, but social media amps up the pressure to provide instantaneous answers. Worse, it accelerates the discussion of responsibility and acceptance of blame, which heighten the pressure during a crisis.

How to communicate effectively around a CBRN incident

  1. Don’t wait for certainty, but have material ready to talk about the CBRN threat: we’ve seen teams deploy infographics and memorable public safety advice in a visual form, alongside clear written holding statements that establish the channel as an authoritative source of information to follow
  2. Keep up the cadence of communication, and explain what seems alarming: we’re sadly familiar with the sight of armed police on British streets especially in big cities but the emergency of cordons for extended periods, HAZMAT suits and decontamination tents is a new challenge for communicators. Don’t underestimate the value of linking to ‘process’ material explaining what the equipment is for, while reiterating what the public should do to keep themselves safe. And not just once, but on a regular basis, to ensure the message bubbles to the top of social feeds as and when people check in.
  3. Tackle misinformation: CBRN is alarming, but there are malicious agents keen to speculate and spread rumours about the nature of the substances involved and the perpetrators behind the incident, to sow community tension. Official voices need to acknowledge what is known and what is still to be confirmed, but shouldn’t be afraid to call out those trying to use the panic and confusion for their own divisive ends
