Effectiveness of Safety Interventions in Fire Engines to Reduce Potential Airborne Transmission of SARS-CoV-2
Physical distancing and wearing a face mask are key interventions to prevent COVID-19. While this remains difficult to practice for millions of firefighters in fire engines responding to emergencies, the delayed forthcoming of evidence on the effectiveness of such safety interventions in this setting presents a major problem. In this field experimental study, we provided initial evidence to close this gap. We examined total aerosol burden in the cabin of a fire engine whilst manipulating crew size, use of FFP2 respirators and use of SCBA full-face masks during 15-min driving periods. At the same time, we controlled for crew activity and speaking, vehicle speed, cabin ventilation, cabin air temperature, pressure and humidity. Limiting the crew size, using FFP2 respirators and not donning SCBA full-face masks was associated with a reduction of the arithmetic mean of total aerosol burden of up to 49%. This study provided initial evidence on the effectiveness of safety interventions in fire engines to reduce potential airborne transmission of SARS-CoV-2 through aerosols. More research about the physical and the clinical effectiveness of such safety interventions is needed.

Comparative Analysis of Post-Earthquake Fires in Japan from 1995 to 2017
Post-earthquakes fires are high-consequence events, which may cause extensive damage once occurred. However, their nature has not been fully investigated as they are low-frequency events at the same time. A questionnaire survey was conducted for the fire services that corresponded to post-earthquake fires in their areas of jurisdiction in recent years, and outline data on fires following nine earthquakes was collected. A database containing information on 665 fires following 11 earthquakes in Japan from 1995 to 2017 was constructed by integrating survey data into an existing database of fires following the 1995 Kobe and 2011 Tohoku earthquakes. Through this database, the features of post-earthquake fires were comparatively analyzed from the viewpoint of types and causes of fire, ignition, fire spread in urban areas, firefighting activity, fatalities, and damage to fire safety equipment systems. The result shows that electrical is increasing in proportion in comparison with the earlier earthquakes among several causes of ignition; about 70% of all ignitions following major earthquakes occurred within a day from the shaking; and the average time required for fire engines to discharge water after ignition increased by 8–25 times in comparison with the ordinary cases. Quantitative correlations for the rate of ignition, \\[ r \\], cumulative relative frequency of ignition, \\[ f \\], and virtual travel speed of fire engines, \\[ v_{FF} \\], that can be used for the risk assessment of post-earthquake fires were also developed. This comparative analysis provides a comprehensive perspective on the issues of post-earthquake fires that have formerly been analyzed fragmentally and construct a technical basis for the future studies.

Measuring Spatial Accessibility of Urban Fire Services Using Historical Fire Incidents in Nanjing, China
The measurement of spatial accessibility of fire services is a key task in enhancing fire response efficiency and minimizing property losses and deaths. Recently, the two-step floating catchment area method and its modified versions have been widely applied. However, the circle catchment areas used in these methods are not suitable for measuring the accessibility of fire services because each fire station is often responsible for the fire incidents within its coverage. Meanwhile, most existing methods take the demographic data and their centroids of residential areas as the demands and locations, respectively, which makes it difficult to reflect the actual demands and locations of fire services. Thus, this paper proposes a fixed-coverage-based two-step floating catchment area (FC2SFCA) method that takes the fixed service coverage of fire stations as the catchment area and the locations and dispatched fire engines of historical fire incidents as the demand location and size, respectively, to measure the spatial accessibility of fire services. Using a case study area in Nanjing, China, the proposed FC2SFCA and enhanced two-step floating catchment area (E2SFCA) are employed to measure and compare the spatial accessibility of fire incidents and fire stations. The results show that (1) the spatial accessibility across Nanjing, China is unbalanced, with relatively high spatial accessibility in the areas around fire stations and the southwest and northeast at the city center area and relatively low spatial accessibility in the periphery and boundary of the service coverage areas and the core of the city center; (2) compared with E2SFCA, FC2SFCA is less influenced by other fire stations and provides greater actual fire service accessibility; (3) the spatial accessibility of fire services is more strongly affected by the number of fire incidents than firefighting capabilities, the area of service coverage, or the average number of crossroads (per kilometer). Suggestions are then made to improve the overall spatial access to fire services.

Prediction model for the water jet falling point in fire extinguishing based on a GA-BP neural network
Past research on the process of extinguishing a fire typically used a traditional linear water jet falling point model and the results ignored external factors, such as environmental conditions and the status of the fire engine, even though the water jet falling point location prediction was often associated with these parameters and showed a nonlinear relationship. This paper constructed a BP (Back Propagation) neural network model. The fire gun nozzle characteristics were included as model inputs, and the water discharge point coordinates were the model outputs; thus, the model could precisely predict the water discharge point with small error and high precision to determine an accurate firing position and allow for the timely adjustment of the spray gun. To improve the slow convergence and local optimality problems of the BP neural network (BPNN), this paper further used a genetic algorithm to optimize the BPNN (GA-BPNN). The BPNN can be used to optimize the weights in the network to train them for global optimization. A genetic algorithm was introduced into the neural network approach, and the water jet landing prediction model was further improved. The simulation results showed that the prediction accuracy of the GA-BP model was better than that of the BPNN alone. The established model can accurately predict the location of the water jet, making the prediction results more useful for firefighters.
