The CBRN stands for chemical, biological, radiological, and the nuclear type of defense. This type of defense takes special measures for the safety in the situations where there are chances of having nuclear, chemical, radiological, and biological hazards. Such cases mainly occur during terrorist attacks. The CBRN defense inhabits avoidance of the contamination, CBRN passive protection, and CBRN mitigation. If a CBRN incident occurs then it is completely hazardous as it causes a situation of mass casualty. In most of the cases, the CRBN incidents are intentional and cause great loss of human lives and property.
