“…Since the flame propagated in subsonic velocity, it can be judged that deflagration occurred in the process of explosion . Soloviova‐Sokolova et al calculated the laminar burning velocity of the benzene‐air mixture was 0.15 m/s at 298 K, 0.1 MPa and lower explosion limit, which clearly illustrated that the peak propagation velocity of the benzene vapor in a confined space would be several times higher. Meanwhile, the explosion pressure in a confined space is usually greater than that in an open area due to lack of heat loss and volume expansion.…”

On May 12, 2018, six workers from Shanghai AIJINKE Engineering Construction Services Co. died on the spot of an explosion when they were maintaining a benzene tank at Shanghai SECCO Petrochemical Co. The incident was characterized as a disastrous incident caused by hot work in a confined space. This article aimed to analyze the incident in a chronological order by using the event sequence diagram. The FLACS software was used to simulate the variation of pressure and temperature over time when benzene vapor was ignited in the tank. Multilayer bow‐tie analysis was adopted to explore the causes of the explosion, along with the corresponding consequences, and preventive measures. The analyses show that the primary causes were the unsafe behaviors of on‐site workers, hazardous conditions of in‐tank substances, risky factors in the construction environment, and deficiencies in process safety management. Based on the qualitative and quantitative analyses, we emphasize three considerable reasons, which include inappropriate flammable gas detection before the operation, failing to test for flammable gases during the hot work, and deficiency of the Management of Change. Finally, the article concludes with a summary of lessons learned as well as suggestions for incident prevention and safety improvement.

The purpose of this paper is to conduct experimental research of hazardous substance emissions at the simulated combustion chamber output. The experiment was carried in a simulated combustion chamber. The combustion chamber included a burner device; a liquid fuel feed system; and a flame tube with two rows of mixing holes and one row of cooling holes. The combustion chamber operation mode was = 0.435, preheat = 423 K, and the atmospheric pressure. The liquid fuel burn rate was 0.77 g/s. The pressure ratio in the combustion chamber remained constant at Δ = 3%. Two types of fuel were used: aviation kerosene of Russia's TS-1 brand and the fuel surrogate was n-decane mixture (C10H22) with benzene additions (C6H6). The benzene additions were 5% through 30% (n-decane/benzene: 95/5, 90/10, 85/15, 80/20, 75/25, and 70/30).
