Joint Biological Point Detection System

BAWS The bio-aerosol warning sensor (BAWS) is an ultraviolet (UV) fluorescence detector using laser illumination. BAWS units are planned to be integrated into the joint biological point detection system (JBPDS) as a trigger for the presence of a 1- to 10-micron-sized biological particle. 

JBPDS The Joint Biological Point Detection System (JBPDS) is in development to replace and outperform the Army BIDS and Navy IBAD systems. It is planned to enter development of Block II in FY 2004. JBPDS comprises trigger, sampler, detection, and identification subsystems to meet Joint Operational Requirements Document (JORD) specifications. It is designed to be able to identify multiple BW agents in less than 15 minutes, at 1 ACPLA sensitivity, and have less than 2 percent error in identification." Generic UV laser-induced fluorescence detection capability (BAWS) improves system performance while reducing operations and support costs. 

The biosensor and response system used a tiered approach. Samples of airborne biological material were taken continuously by the Joint Biological Point Detection System (JBPDS) equipment, which was not commercially available. Operation of these systems was monitored continuously at a separate control facility. Initial detection by the JBPDS equipment was followed by a second-tier assay analysis that, if positive, would result in physical collection of sampled material for additional analysis off-site. The confirmed second-tier analysis would result in notification of JBPDS leadership and shipment of a sample to the Utah Department of Health for further laboratory analysis. Because the confirmatory test would take 12-24 hours to complete, the primary function of the higher-tiered detection was to define treatment and decontamination responses (LP-3 options). Change in building or HVAC operation on the fifth and sixth floors would not be initiated until the Utah Department of Health analysis confirmed detection of a biological threat agent.

The sensors proposed and used for contamination avoidance should have utility in decontamination. The committee is not aware, however, of any assessment aimed at finding out how well the sensors developed for contamination avoidance can support decontamination and resumption of operations. There are also opportunities to leverage sensor investments with water and food safety. The DOD development of a sensor for water safety (joint chemical/biological agent water monitor) is at an early stage, with planned entry into development in FY 2005. Several references provide descriptions and status reports of biological point detection systems within the DOD.1 Table C.2 offers a summary.
