Crime Scene Investigations for Hazardous Environments (PER-228)

This course addresses response in a hazardous environment, with emphasis on forensic evidence collection and recovery. The purpose of the course is to provide participants with the knowledge, skills, and abilities to investigate a hazardous environment crime scene, as defined by the International Association for Identification’s Crime Scene Certification Board. 

The modules are designed to fit together and progress in such a way that, by the end of the course, participants will have developed 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 or TIC and non-CBRNE or TIC forensic evidence.
