PER-228 Advanced Forensic Investigations for Hazardous Environments

Monday, September 28, 2020 - Thursday, October 1, 2020

8:00 AM - 5:00 PM Daily


Course Description


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.


Course Objectives


  • Name three crime scene considerations for CBRNEITIC-contaminated environments
  • Analyze and present case studies involving CBRNE/TIC agents or materials
  • Differentiate the functions and responsibilities of the CBRNE crime scene investigation unit (CSIU) Group members
  • Examine the FBI's 12-step process for crime scene management as it relates to the operations of a CBRNE CSIU Group
  • Explain why effective monitoring and detection is essential at a hazardous environment crime scene, contaminated with CBRNE/TIC agents or materials
  • Relate knowledge of chemical and physical properties of materials to effective monitoring and detection
  • Locate, document, collect, and preserve physical evidence from a mock CBRNE/TIC-contaminated crime scene
  • Field-screen evidence using pH paper, radiation detectors, photoionization detectors, and a combustible gas indicator
  • Select appropriate PPE based on hazard and risk assessment, types of harm, hazard physical state, concern level, and amount
  • Recognize limitations of using PPE in a CBRNE/TIC agent or material hazardous environment
  • Inspect, don, function in, and doff PPE following proper procedures in a simulated CBRNE/TIC hazardous environment
  • Describe the principles for decontaminating evidence, equipment, and personnel
  • Collect and package all types of evidence at least once as the evidence facilitator and once as the evidence collector
  • Document, process, collect, and package latent fingerprints, hair and fiber evidence, serological and DNA evidence, trace and transfer evidence, and impression evidence according to prescribed procedures and using the appropriate collection and packaging equipment
  • Describe various methods of crime scene documentation
  • Discuss the use of crime scene mapping technologies in a CBRNE/TIC-contaminated environment
  • Collect data using a laser scanner and global positioning system (GPS)
  • Identify three CBRNE/TIC agent or material clandestine laboratories by recognizing and distinguishing lab equipment, processes, notes, and precursor materials and identifying evidence recovery sites
  • Use supplied reference materials and the Participant Guide to establish evidence types, CBRNE/TIC forensic evidence recovery locations, conventional forensics evidence types and locations, safety and evidence recovery priorities, and evidence recovery plan for two labs
  • Describe indicators of CBRNE/TIC agents or materials at a crime scene
  • Recover physical forensic evidence (CBRNE/TIC and conventional) at a CBRNE/TIC-contaminated crime scene, following proper procedures
  • Distinguish the role of the CSI at a CBRNE/TIC-contaminated crime scene versus the non-CBRNE/TIC­ contaminated crime scene
  • Select appropriate evidence collection protocols, procedures, documentation equipment, screening equipment, packaging equipment, and protective equipment for entering a hazardous environment crime scene contaminated by CBRNE/TIC agents or materials
  • Document, screen, classify, process, collect, package, and preserve multiple items of contaminated conventional and CBNRE/TIC forensic evidence at a hazardous environment crime scene contaminated by CBRNE/TIC agents or materials
  • Describe the after-action report (AAR), post-incident debriefing, and critical stress impacts
