Abstract Introduction Blast overpressure health hazard assessment is required prior to fielding of weapon systems that produce blast overpressures that pose risk of auditory and nonauditory blast lung injuries. The anthropomorphic blast test device (ABTD) offers a single device solution for collection of both auditory and nonauditory data from a single blast at anthropometrically correct locations for injury risk assessment. It also allows for better replication of personnel positioning during weapons firings. The ABTD is an update of the blast test device (BTD), the current Army standard for collection of thoracic blast loading data. Validation testing of the ABTD is required to ensure that lung injury model validated using BTD collected test data and sheep subjects is still applicable when the ABTD is used. Methods Open field validation blast tests were conducted with BTD and ABTD placed at matching locations. Tests at seven blast strength levels were completed spanning the range of overpressures for occupational testing. Results The two devices produced very similar values for lung injury dose over all blast levels and orientations. Conclusion The ABTD was validated successfully for open field tests. For occupational blast injury assessments, ABTD can be used in place of the BTD and provide enhanced capabilities.

This paper evaluates the reliability of the currently used climate-based indices in selecting a moisture reference year (MRY) for the freeze-thaw (FT) damage risk assessment of internally insulated solid brick walls. The evaluation methodology compares the ranking of the years determined by the climate-based indices and response-based indices from simulations, regarded as actual performance. The hygrothermal response of an old brick masonry wall assembly, before and after retrofit, was investigated in two Canadian cities under historical and projected future climates. Results indicated that climate-based indices failed to represent the actual performance. However, among the response-based indices, the freeze-thaw damage risk index (FTDR) showed a better correlation with the climate-based indices. Additionally, results indicated a better correlation between the climatic index (CI), the moisture index (MI), and FTDR in Ottawa; however, in Vancouver, a better fit was found between MI and FTDR. Moreover, the risk of freeze-thaw increased considerably after interior insulation was added under both historical and projected future climates. The risk of FT damage would increase for Ottawa but decrease for Vancouver under a warming climate projected in the future, based on the climate scenario used in this study. Further research is needed to develop a more reliable method for the ranking and the selection of MRYs on the basis of climate-based indices that is suitable for freeze-thaw damage risk assessment.

Предложена математическая модель и рассчитаны значения риска причинения вреда (ущерба) в результате пожаров в субъекте Российской Федерации. Субъекты Российской Федерации распределены по категориям уровня обеспечения пожарной безопасности в зависимости от расчетного значения риска причинения вреда (ущерба) в результате пожаров в субъекте Российской Федерации. Предложены оценки результатов деятельности ГУ МЧС России в зависимости от риска причинения вреда (ущерба) и категории уровня обеспечения пожарной безопасности, к которому отнесены субъекты Российской Федерации. The regulatory legal acts of the Russian Federation establish that the criteria for assigning objects of control to the categories of damage risk should be formed based on the results of the damage risk assessment. In the developed countries of the world, as a rule, the distribution of objects of control by risk categories is used to justify the frequency of their inspections and is carried out depending either on the point risk assessment or on the number and seriousness of violations of mandatory fire safety requirements identified during the inspection of the object of control. In the literature sources there are no mathematical models for determining the damage risk as a result of a fire in buildings for evaluating the activity results of fire authorities (Main offices of EMERCOM of Russia). The purpose of this work was to develop and test a mathematical model for evaluating the activity and rating of the Main offices of EMERCOM of Russia for the subjects of the Russian Federation based on the category of fire safety level. As a criterion for assigning the subjects of the Russian Federation to different categories of fire safety level it is proposed to use the damage risk as a result of a fire in buildings located on the territory of the corresponding subject of the Russian Federation. The mathematical model has been developed to determine the damage risk of causing harm (damage) as a result of a fire in a building and there is given its assessment for buildings on the territory of each subject of the Russian Federation. There was carried out the distribution of the subjects of the Russian Federation according to the categories of fire safety based on the calculated value of damage risk. It is shown that such distribution significantly depends on the objectivity of statistical information on fires and the number of buildings on the territory of each subject of the Russian Federation. The assessment of the activity results for each of 86 EMERCOM of Russia Main offices was made and they were rated based on the category of fire safety level of the corresponding subject of the Russian Federation.
