This NRIFD report is an investigation into the fire defense response to the 2011 earthquake. Efficiency of the response was decreased due to widespread damage, loss of infrastructure, and preparedness for a following tsunami. The investigation reviews activities that worked…
As photovoltaic systems are becoming more common, so is the probability of electric shock to firefighters from the systems. This report confirms and quantifies how flame light from a fire can generate power in a photovoltaic system and thereby lead…
One of the dangers to firefighters in a photovoltaic power system fire is an electric shock. In this study, NRIFD investigated the attenuation effect on power generation of photovoltaic modules with various shieldings.
While photovoltaic systems are become widely used in applications from houses to mega solar power plants, we have insufficient knowledge about fire behavior, firefighting, and safety for firefighters in photovoltaic system fires. In this publication, NRIFD carried out experiments covering…
On January 13, 2010, a fire occurred in downtown Beppu-City, Japan, that burned one city block, including 22 residential houses. The fire spread was attributed to high winds and the close proximity of the wooden houses. Many residents did not…
This report is NRIFD’s investigation of a significant fire in Beppo-City, Oita prefecture, in 2010. The fire spread quickly due to strong winds and a delay in reporting the fire to the fire department. The report looks at the firefighting…
Lessons were learned from comparing an environmental emergency prediction system simulation with the actual events of the 2011 Great Higashi-Nihon Earthquake. This report focuses on how these lessons will be implemented into a large building fire simulator and the issues…
This paper presents a new approach for visualizing disaster prevention information during a disaster response or drill using augmented reality. The system uilizes a smartphones’ powerful CPU, camera, accelerometers, GPS, and solid state compass along with a map consisting of…
In order to properly design sprinkler systems, techniques are necessary to evaluate their performance. NRIFD proposes a technique for evaluating the performance of a sprinkler system by using data of water distribution on the ground from one sprinkler head, and…
In order to advance the firefighting tactics for oil tank fires, the influences of oxygen-reduced nitrogen-enriched air on the behavior of a small scale n-heptane tank fire was experimentally investigated. The results support the use of high-power water spray systems…
