The work of crime scene investigators (CSIs) is made more complicated when the scene is contaminated by either chemical, biological, radiological, nuclear, explosives (CBRNE) or toxic industrial chemicals (TICs). Special considerations must be observed when working at such scenes, whether they are the result of acts of terrorism, accidents, or natural disasters. This volume is a comprehensive reference containing guidelines and best practices for keeping CSIs safe and conducting a thorough crime scene investigation in these deadly environments. Protocols are provided for how to best identify, document, collect, and preserve physical evidence.
