The overall objective of the technology evaluation described in this test/QA plan is to evaluate the performance of decontamination technologies using biological agents (including toxins) and surrogates under a range of realistic conditions. Testing may be conducted over ranges of temperature and relative humidity representing those that might be encountered in a decontamination situation in a building environment. The performance parameters on which the decontamination technologies will be evaluated under this plan include: log kill or efficacy (the logarithm (base 10) of the number of colony-forming units (CFUs) removed/destroyed by applying the decontamination technology) and surface damage caused by the decontamination technology. The evaluation to be conducted under this plan is limited to detection of biological warfare agents (or surrogates) or toxins in or on individual samples (test coupons) of indoor materials. Testing will be conducted in two phases. The initial phase will take place in a naive area (not a biological safety laboratory) and the second phase will take place in a biosafety level (BSL) 3 area. In the initial phase, the decontamination technology will be coupled with the test chamber, associated monitoring devices will be installed in the test chamber and the vendor staff will train the MREF staff regarding use of the decontamination technology. In addition, the MREF staff will verify that all sub-systems comprising the testing apparatus are in working order. The second phase of the testing entails evaluating the performance of the decontamination technology using live agent. This evaluation will be performed in a BSL-3 in the MREF.
