“…For instance, the toluene detection limit required in the indoor air quality standard of China (IAQS, GB/T 18883-2002) is under 47 ppb [13]. Meanwhile, the diffusion of toluene in the air has the potential to form explosive mixtures, posing the risk of fire and explosion accidents when exposed to open flames or large amounts of heat [14][15][16]. Therefore, timely leak detection and emission monitoring of toluene are extremely crucial, which facilitates treatment and control in early time so as to minimize risks and dangers.…”

Rapid detection of low concentration toluene is highly desirable in environment monitoring, industrial processes, medical diagnosis, etc. In this study, we prepared the Pt-loaded monodispersed nanoparticles through hydrothermal synthesis and assembled a toluene sensor with fast response and low detection limits based on Micro-Electro-Mechanical System (MEMS). Compared with the pure SnO2, the 3 wt% Pt-loaded SnO2 sensor exhibits a 2.75 times higher gas sensitivity to toluene gas at about 330 °C. Meanwhile, the 3 wt% Pt-loaded SnO2 sensor also has a stable and good response to 100 ppb of toluene. Its theoretical detection limit was calculated as low as 12.6 ppb. Also, the sensor has a short response time of ~10 s at different gas concentrations (even down to 5.4 s at 20 ppm), as well as the excellent dynamic response-recover characteristic, selectivity, and stability. The improved performance of Pt-loaded SnO2 sensor can be explained by the increase of oxygen vacancies and chemisorbed oxygen. In our MEMS sensors, three gas sensing elements could be packaged in one ceramic shell for parallel testing and made it easier for real application by embedding in a printed circuit board. This provides new ideas and decent prospect for developing miniaturized, low-power-comsumption, and portable application of gas sensing devices.

“…Between 2008 and 2018, flammable liquids were the most common cause of chemical accidents in South Korea (52.1%) [1]. In addition, in China between 2000 and 2020, 74% of industrial accidents were due to explosions and fires [2].…”

Heat-Induced Increase in LPG Pressure: Experimental and CFD Prediction Study

et al. 2023

Computational fluid dynamics (CFD) has become a widely used tool for predicting hazardous scenarios. The present study aimed to assess CFD prediction applied to LPG containers under heating. Thus, two cylinders, each filled with propane or butane, were experimentally exposed to fire, and the pressure increment was recorded. The results were compared with those provided by a CFD method (Ansys Fluent). The limitations of the method are discussed, and a trend in the error increment and its relation to the reduced temperature increment are presented. The results obtained show that the computational method had a good agreement, with a relative error of 19% at a reduced temperature equal to 2. Furthermore, the method had a better fit with heavier alkanes, as the butane was less influenced by temperature overestimation compared with propane.

“…The main risks in manufacturing are injuries owing to contact with objects or machinery, falls, and repetitive motion. The main causes that trigger an accident at work are design failure, pipe or valve faults, equipment failure or damage, electrical damage, improper maneuvering or operation, inadequate safety management, insufficient safety protection measures, and fortuitous events [15]. Human talent is still a critical factor in accidents; most accidents (between 70 and 90%) are due to human error [10].…”

Ecuador is a country in South America, where, in 2021, there were 849,874 companies that had total sales of USD 105.23 billion, which had 2,698,650 workers. This study was carried out with the aim of analyzing occupational accidents by industry type in Ecuador, focusing mainly on the construction and manufacturing industries. The data were provided upon express request to the National Directorate of General Occupational Risk Insurance of the Ecuadorian Social Security Institute. The data used in this study concerned accidents involving qualified workers affiliated with the Ecuadorian Social Security System. The data obtained were used to calculate the general accident rate, accident rate by sector, permanent disability rate, and mortality rate. Between 2016 and 2019, 6960 qualifying accidents occurred in Ecuador. Approximately 89.71 ± 0.36% of the accidents investigated involved men, and 50.28 ± 2.49% of these accidents caused permanent disability. The mortality rate was, on average, 10.60 ± 1.83%, 2018 being the year with the most deaths due to accidents at work. The Ecuadorian sector with the highest accident rate was the manufacturing industry with 26.15 ± 2.50%, followed by the construction industry with a rate of 17.47 ± 3.59%. The manufacturing industry had the highest rate, with a significant difference of accidents that resulted in permanent disability, with an average of 31.79 ± 2.85%, while the construction sector had the highest rate of fatal accidents, with an average of 25.82 ± 5.05%. This is the first study to report the number of qualified occupational accidents in Ecuador. With this study, a starting point is established for future analyses of the evolution of occupational accidents by type of industry in Ecuador. Future studies could determine the increase or decrease in the number of accidents, evaluate rates of permanent disability and death, and establish risk factors and preventive measures for each task or activity in all productive sectors.
