“…Proper safe handling of the reactions is necessary for handling the chemicals and performing its operations according to OSHA (Yu et al, 2017). Electrostatic energy causes huge explosions in the chemical and pharmaceutical industries due to its accumulation of charged particles, which are not dissipated and discharged properly (Egan, 2017;Chen et al, 2021;Ebadat & Cartwright, 2023). To dissipate and discharge the electrostatic energy to the ground we can use double earthing, jumpers to the operation equipment, earth rite system, touch pads, wrist straps, personal tester, and electrostatic energy discharge (ESD) flooring (Yang et al, 2021;Zhang et al, 2023).…”

Implementation of the fourteen elements of process safety management (PSM) helps to build a good safety culture in the organization. The new three-dimensional approach, which consists of good safety practices, safety precautions, and frequent checking of the process equipment and its devices has been applied to the various elements of the process safety management. The elements of process safety management are six, four, and three are good safety practices, safety precautions, and frequent checking of process equipment and its devices but one of the elements is the combination of all the three-dimensional approach, which is a trade secret, which insists that all the people in the organization should follow all the documented procedures from two to thirteen elements of the process safety management, the controlled copy should only be used inside the company premises. We have taken secondary published data for assessing the deviations of the three-dimensional safety approach for the human failures in the pharmaceutical industry, which has led to various incidents/accidents from October 2017 to September 2021. The deviation, which we have observed for the good safety practices, safety precautions, and frequent checking of process equipment and its devices was ten, nine, and one numbers before implementation of the process safety management. After the implantation of the process safety management, the incidents were reduced to three numbers from January 2022 to August 2023, in which deviation has been found in the two and one for the good safety practices and safety precautions.

“…However, the existing research works have not paid enough attention to the explosion flame propagation characteristics under pressure accumulation, which makes it impossible to accurately and comprehensively describe the flame propagation mechanism(s) in the real explosion process. Various studies have shown that explosion pressure significantly affects the flame propagation behavior, such as flame thickness and propagation velocity, thereby affecting the flame propagation mechanism(s) [27][28][29][30]. In addition, due to the confinement of the closed space wall, the product of the high temperature and high pressure produced by the explosion process cannot be released in time.…”

In order to study the flame propagation characteristics of a ethylene/polyethylene hybrid explosion under pressure accumulation, a visual pressure-bearing gas/power hybrid-explosion experimental platform was built. The flame propagation characteristics of polyethylene and ethylene/polyethylene hybrid explosions in the closed vessel were analyzed. The results show that the flame brightness, flame front continuity and average flame propagation velocity of polyethylene dust explosion in the closed vessel increased first and then decreased when the polyethylene dust concentration increased. The curve of the flame propagation velocity with time had obvious pulsation characteristics. Adding 1% and 3% ethylene to different concentrations of polyethylene dust significantly improved its explosion flame brightness, flame front continuity and average flame propagation velocity. Moreover, it also improved the fluctuation amplitude of the explosion flame propagation velocity with time curve. The explosion flame of the polyethylene dust and ethylene/polyethylene hybrid mixture included four zones during the propagation process, which were denoted as the unburned zone, preheated zone, premixed flame zone and dust flame zone. The addition of ethylene to polyethylene dust can significantly increase its thickness of premixed flame zone and preheated zone, and the thickness increased when the ethylene concentration increased.
