Advanced Forensic Investigations for Hazardous Environments (PER-228)



This course addresses response in a hazardous environment, with emphasis on evidence collection and recovery, as well as the paradigm shifts that are required for crime scene investigators to safely conduct a crime scene investigation in these types of environments. The course is designed so that participants will develop the required knowledge, skills, and ability to investigate a chemical, biological, radiological, nuclear, and high-yield explosive (CBRNE), toxic industrial chemical (TIC), or hazardous environment crime scene for the identification, documentation, presumptive field testing, preservation, and collection for laboratory analysis of CBRNE/TIC and non-CBRNE/TIC forensic evidence. 

The course will address these areas by following the FBI 12-step crime scene management process as applied to a high consequence event. This will enable participants to properly collect evidence that may be used in a criminal prosecution. Finally, the course is intended to enhance the participants' skills needed to provide expert testimony for the successful prosecution of the perpetrators of a criminal hazardous environment.
