Risk-led scene strategy
Translate hazard information and investigative objectives into defensible entry, search and recovery priorities.
CBRN Forensics · Contaminated-scene investigation
Forensic work in chemical, biological, radiological and nuclear environments.
CBRN forensic work connects hazard characterisation, responder protection and contamination control with lawful recovery, scientific integrity and evidential continuity.
What is CBRN forensics?
CBRN forensics is the application of forensic strategy, documentation, sampling and evidence management where chemical, biological, radiological or nuclear hazards change how a scene can be entered, examined and transferred to laboratories. Safety controls and evidential decisions must be planned together rather than treated as separate phases.
Hazard controls and forensic requirements are interdependent.
Zoning, PPE, measurement, exposure limits, contamination control, sampling, packaging, decontamination and transport all affect what can be recovered and how findings can later be interpreted. The operational plan must connect investigators, scientists, CBRN advisers, incident command, laboratories and prosecutors.
Analytical dimensions
Four connected aspects of the field.
The categories below organise the principal operational, scientific and evidential questions without prescribing a single institutional model.
Contamination-aware recovery
Plan access, documentation, sampling, packaging and transfer to control both responder exposure and cross-contamination.
Forensic–laboratory interface
Define sample purpose, chain of custody, transport conditions and analytical questions before material leaves the scene.
Multi-agency exercise design
Test how police, CBRN, laboratory, medical and justice functions exchange authority and information.
Methodological perspective
Operational practice, published guidance and research are considered together.
The field is examined through observable decisions, inter-agency dependencies, evidential continuity and the limits of available methods. Practical experience provides questions and context; it does not replace discipline-specific standards, validation or competent authority.
ScopeDelivery is adapted to national law and local procedures. Regulated activities and formal certification remain with the competent or accredited authority.
Place within the wider TSM knowledge map.
This field is considered as one part of complex-scene management. Its terminology, methods and limits should be read together with the relevant legal framework, professional guidance and peer-reviewed evidence.
