To elucidate the subjective thermal strain of workers in kitchen working environments, we performed a cross-sectional study involving 991 workers in 126 kitchen facilities in Japan, using a self-reporting questionnaire survey and subjective judgment scales (SJS). The ambient temperature, mean radiant temperature (MRT), and wet-bulb globe temperature (WBGT) index were measured in 10 kitchen faci...
Natural gas station is an important part of the whole natural pipeline transmission system, in which vibration a hidden danger that cannot be ignored for safe operation station. In view severe enterprise, acceleration sensors are used to test each measuring point under different working conditions, and then three-dimensional finite element model established by using numerical simulation softwar...
Background and purpose: Vulnerability introduces the sensitivity of a system versus internal faults or external threats. A vulnerable system cannot recover itself after shocks and may disable to provide services. I in this study in order to achieve a resilient city gate station (CGS), vulnerability of the system identified via SVA procedure. Moreover, using the resilience engineering approach s...
There are similar algorithms and infrastructure for storing gas fuels at CNG (Compressed Natural Gas) and CHG (Compressed Hydrogen Gas) fuelling stations. In these stations, the fuels are usually stored in the cascade storage system to utilize the stations more efficiently. The cascade storage system generally divides into three reservoirs, commonly termed low, medium and high-pressure reservoi...
BACKGROUND A study was performed on the accidental chlorine gas leakage that occurred in a factory of printed circuit boards manufactured without chlorine. Health examination was performed for all 52 workers suspected of exposure to chlorine gas, and their evacuation-related behaviors were observed in addition to analyzing the factors that affected the duration of their acute respiratory sympto...
