This technology evaluation report included use of low-tech decontamination methods on surfaces common to outdoor residential environments and included evaluating the decontamination efficacy, method constraints, safety concerns, feasibility, waste generation, potential exposure, ...

The overall goal of this project is to provide the general public, emergency responders, and healthcare workers with initial information on the effectiveness of selected disinfection/cleaning technologies and commercial off-the-shelf (COTS) products for the disinfection/cleaning ...

Following a bioterrorism event, an incident or unified command would be established, the impacted area would be characterized, and response work zones set up based on the extent of indoor/outdoor contamination. The personnel decontamination (decon) line, established in the contam...

The primary objectives of this project research effort were to analyze the potential for application of an aggressive air sampling (AAS) technique for measurement of spores resulting from a dissemination of a biological agent, Bacillus anthracis (Ba), in an indoor environment and...

An urban subway system is a logical target for the release of a biological agent. A typical subway platform at rush hour offers numerous confined targets, a train-driven mechanism for extended and rapid dissemination, and minimal security. Results from the UTR program suggest tha...

Bacillus anthracis, the causative agent for anthrax, is a dangerous pathogen to humans and has a history as a bioterrorism agent. While sampling methods have been developed and evaluated for characterizing and clearing contaminated indoor sites, the performance of these sampling ...

The main objective of this study was to compare the re suspension of an inert sugar-based surrogate, known as DNA Tagged Reagents for Aerosol Experiments (DNATrax) developed by Lawrence Livermore National Laboratory (LLNL) under variable humidity conditions for an underground sub...

The Underground Transport Restoration (UTR) Operational Technology Demonstration (OTD) was a full-scale study focused on remediation of a subway system after contamination with a Bacillus anthracis (Ba) surrogate (Bacillus atrophaeus, subspecies globigii [Bg]). The study involved...

Combined slides from all CESER/HSMMD PIs that conduct research under AnCOR for the APril 27/28 Quarterly meeting with DHS and USCG

Responding to an accident, fire, or deliberate chemical release can potentially expose first responders to harmful levels of toxic or corrosive chemicals. Additionally, following a contaminant release indoors, it is essential to protect the public health and provide a clearance ...

Brief overview presentation for the quarterly UTD meeting with DHS, LANL, LLNL, MIT LL, ANL, and EPA. This presentation will provide a status update on the EPA's DNATrax and Btk resuspension testing (REBOUNDS).

This Presentation Aims: To obtain quantitative efficacy data of two ultraviolet light (UVC) technologies for surface inactivation of Bacillus anthracis Ames and Bacillus atrophaeus spores.

During personnel decontamination, conventional backpack sprayers are often used to distribute liquid decontaminant over PPE surfaces, and this process generally produces significant volumes of liquid waste and may lead to migration of biological agents..Following a bioterrorism e...

This research assessed in silico the feasibility of a bioaerosol sampling network to monitor Bacillus anthracis spore concentrations during the remediation phase following a large-scale biological contamination incident. We modeled the performance and cost of four air sampling st...

In the event of a release of a biological agent in an urban area, a wide range of surfaces may be contaminated, including indoor surfaces in homes and businesses. This research was conducted to identify and evaluate low-technology (low-tech) remediation methods that could be used...

Personnel decontamination is an integral part of any emergency response. This report discusses a decontamination project that evaluated the decontamination efficacy and physical migration (transport) of Bacillus spores and operational efficiency of two types of sprayer technologi...
