A CBRN specialist response is a coordinated response to a chemical, biological, radiological or nuclear incident. CBRN is the umbrella term that brings those four different hazard categories into one response context. The shared term allows the response to be described as a whole while retaining the category named for the incident.
JESIP describes one continuous multi-agency response. It begins with the initial operational response and develops as CBRN-protected resources arrive. Protected resources join work already under way and add capability as the response develops. Initial and protected activity belong to the same continuing multi-agency effort.
Shared work before the cause is known
Emergency services work together to save life, investigate, resolve the emergency and support recovery. Those functions can begin before responders know whether the cause is deliberate or accidental. The four functions describe the public work of the response, while the cause may still be a question for investigation.
That timing gives investigation a place alongside the other functions from the outset. Saving life, resolving the emergency and supporting recovery do not require a settled answer about whether the incident arose deliberately or accidentally. The response can continue to develop as protected resources arrive while the participating services carry out the functions appropriate to the same incident.
Specialist capabilities and scalable coordination
England’s National Co-ordination and Advisory Framework lists detection, identification and monitoring, together with mass decontamination, as specialist CBRN capabilities. Detection, identification and monitoring are grouped together in the framework, while mass decontamination is named alongside them. These are the high-level capabilities attached to the specialist part of the response.
The shared emergency functions and the specialist capabilities answer different questions. Saving life, investigation, emergency resolution and recovery describe what the services work together to achieve. Detection, identification, monitoring and mass decontamination describe capabilities available within the developing CBRN response as specialist resources contribute to it. Protected resources bring those capabilities into the same public functions already under way. Capability and coordination remain separate: one concerns the specialist work available, while the other concerns support around local capacity.
The framework also provides scalable coordination when local capacity needs support. Scalable coordination brings support around that local capacity within the continuous response. Its shared functions are already under way, protected resources contribute the named capabilities, and the level of coordination can adjust to the support needed locally.
