ABSTRACT
CSIs will have to make some dramatic changes in the ways they conduct crime scene investigations involving environments contaminated by CBRNE/TIC agents. ¨is chapter discusses the many paradigm shi´s to which CSIs must adapt when they move into a hazardous environment to process a crime scene. Most notably is the fact that they have been trained not to introduce any contamination into the scene, but now they must realize that the scene has already been contaminated, and it is up to them to reduce the possibility of cross-contamination as well as make it a priority to keep themselves and others safe from the harmful e«ects of CBRNE/TIC agents.
