Assessment of Law Enforcement Chemical, Biological, Radiological, and Nuclear Personal Protective Equipment Audible Signature.

摘要

Tactical law enforcement (LE) officers need to wear commercial chemical, biological, radiological, and nuclear (CBRN) personal protective equipment (PPE) during operations such as clandestine laboratory responses, barricaded CBRN terrorist responses, or downed-officer evacuations under hazardous atmospheric conditions. Audible signature refers to the noise a tactical officer or his or her equipment may make that could lead to detection by a threat. Some characteristics of CBRN PPE may increase an officer s audible signature and make stealth operations more challenging or impossible. The goal of this effort was to investigate the audible signature characteristics of multiple LE CBRN PPE ensembles when worn with tactical LE equipment. Multiple statistically significant audible signature differences were found among the CBRN PPE ensembles evaluated.
