Sandia will provide technical assistance to Helpful Engineering to develop and test the Universal Citizen Protection Device (UCPD) which is a UV-based filter-less PPE concept that aims to keep the Sars-CoV-2 virus out of eyes, nose and mouth with a 99%+ reliability. The heart of the device would be a concealed UV Chamber that decontaminates all air going in and out of the PPE. Helpful Engineering’s goal is to build this device to be reusable and cost less than $100 to construct and can be worn for 8 hours. The UCPD is an open source project, and once developed, prototyped, tested and approved, it will be shared with interested manufacturers globally.

Sandia will provide technical assistance to New Mexico Department of Health to provide analysis of SafeGraph mobility data (for which Sandia already has the data and a Data Use Agreement in place with the data provider). Sandia will produce analysis to determine the contribution of travel to SARS-CoV-2 spread within New Mexico.

Sandia provided technical assistance to RingIR to test and evaluate of the RingIR molecular detector. The detector can identify gas phase species using molecular fingerprinting and has potential application for SARS-CoV-2 detection in near real time. As part of the development process Sandia will utilize the biological aerosol test bed deployed at the Aerosol Complex to evaluate the penetration of MS2 bacteriophage aerosol through the RingIR system. The objective of this project is to provide experimentally derived measurements of the RingIR molecular detector penetration efficiency, including external exhaust filter for mitigation of exhaust aerosol and operation using MS2 bacteriophage as a biological surrogate to the SARS-CoV-2 virus.

Sandia National Laboratories (SNL) conducted an independent assessment of three different certified N95 respirators for the State of New Mexico Department of Homeland Security and Emergency Management. The testing conducted under this effort mimicked traditional NIOSH certification testing methodologies, where possible (NIOSH 2019). This included the use of a commercially available off-the-shelf (COTS) instrument typically used in industry for N95 respirator certification (ATI 2018). The COTS system, an Air Techniques International 100Xs automated filter tester, was used for all the testing reported in this document. It is important to note that SNL is NOT a certification laboratory, and all quantitative results are for informational purposes only. Additional technical information of N95-related efforts conducted by this team may be found in: Omana et al. (2020a), Omana et al. (2020b), Celina et al. (2020)
